                           The Library of Congress,
                           Washington, DC, January 2, 2001.
Hon. Jesse Helms,
Chairman, Committee on Foreign Relations,
U.S. Senate, Washington, DC.
    Dear Mr. Chairman: In accordance with your request, we have 
revised and updated the study ``Treaties and Other 
International Agreements: The Role of the United States 
Senate,'' last published in 1993. This new edition covers the 
subject matter through the 106th Congress.
    This study summarizes the history of the treatymaking 
provisions of the Constitution and international and domestic 
law on treaties and other international agreements. It traces 
the process of making treaties from their negotiation to their 
entry into force, implementation, and termination. It examines 
differences between treaties and executive agreements as well 
as procedures for congressional oversight. The report was 
edited by Richard F. Grimmett, Specialist in National Defense. 
Individual chapters were prepared by policy specialists and 
attorneys of the Congressional Research Service identified at 
the beginning of each chapter.
    The Congressional Research Service would like to thank 
Richard Douglas, Chief Counsel of the Committee, Edwin K. Hall, 
Minority Staff Director of the Committee, Brian P. McKeon, 
Minority Counsel of the Committee, and Robert Dove, 
Parliamentarian of the Senate, for their comments on Senate 
procedures for consideration of treaties. We would also like to 
thank Robert E. Dalton, Assistant Legal Adviser for Treaty 
Affairs, Department of State, and other staff members of the 
Treaty Office for their assistance with various factual 
questions regarding treaties and executive agreements.
            Sincerely,
                                       Daniel P. Mulhollan,
                                                          Director.

                           INTRODUCTORY NOTE

                              ----------                              

    This study revises a report bearing the same title 
published in 1993. It is intended to provide a reference volume 
for use by the U.S. Senate in its work of advising and 
consenting to treaties. It summarizes international and U.S. 
law on treaties and other international agreements. It traces 
the process of making treaties through the various stages from 
their initiation and negotiation to ratification, entry into 
force, implementation and oversight, modification or 
termination--describing the respective senatorial and 
Presidential roles at each stage. The study also provides 
background information on issues concerning the Senate role in 
treaties and other international agreements through specialized 
discussions in individual chapters. The appendix contains, 
among other things, a glossary of frequently used terms, 
important documents related to treaties: the Vienna Convention 
on the Law of Treaties (unratified by the United States); State 
Department Circular 175 describing treaty procedures in the 
executive branch; the State Department regulation, 
``Coordination and Reporting of International Agreements,'' and 
material related to the Case-Zablocki Act on the reporting of 
international agreements to Congress. Also included are a list 
of treaties approved by the Senate from January 1993 through 
October 2000, examples of treaty documents, and an annotated 
bibliography.


                 I. OVERVIEW OF THE TREATY PROCESS \1\
---------------------------------------------------------------------------

    \1\ Prepared by Richard F. Grimmett, Specialist in National 
Defense.
---------------------------------------------------------------------------
                              ----------                              

    Treaties are a serious legal undertaking both in 
international and domestic law. Internationally, once in force, 
treaties are binding on the parties and become part of 
international law. Domestically, treaties to which the United 
States is a party are equivalent in status to Federal 
legislation, forming part of what the Constitution calls ``the 
supreme Law of the Land.''
    However, the word treaty does not have the same meaning in 
the United States and in international law. Under international 
law, a ``treaty'' is any legally binding agreement between 
nations. In the United States, the word treaty is reserved for 
an agreement that is made ``by and with the Advice and Consent 
of the Senate'' (Article II, Section 2, Clause 2 of the 
Constitution). International agreements not submitted to the 
Senate are known as ``executive agreements'' in the United 
States, but they are considered treaties and therefore binding 
under international law.
    For various reasons, Presidents have increasingly concluded 
executive agreements. Many agreements are previously authorized 
or specifically approved by legislation, and such 
``congressional-executive'' or statutory agreements have been 
treated almost interchangeably with treaties in several 
important court cases. Others, often referred to as ``sole 
executive agreements,'' are made pursuant to inherent powers 
claimed by the President under Article II of the Constitution. 
Neither the Senate nor the Congress as a whole is involved in 
concluding sole executive agreements, and their status in 
domestic law is not fully resolved.
    Questions on the use of treaties, congressional-executive 
agreements, and sole executive agreements underlie many issues. 
Therefore, any study of the Senate role in treaties must also 
deal with executive agreements. Moreover, the President, the 
Senate, and the House of Representatives have different 
institutional interests at stake, a fact which periodically 
creates controversy. Nonetheless, the President, Senate, and 
House share a common interest in making international 
agreements that are in the national interest in the most 
effective and efficient manner possible.
    The requirement for the Senate's advice and consent gives 
the Senate a check over all international agreements submitted 
to it as treaties. The Senate may refuse to give its approval 
to a treaty or do so only with specified conditions, 
reservations, or understandings. In addition, the knowledge 
that a treaty must be approved by a two-thirds majority in the 
Senate may influence the content of the document before it is 
submitted. Even so, the Senate has found it must be vigilant if 
it wishes to maintain a meaningful role in treaties that are 
submitted.
    The main threat of erosion of the Senate treaty power comes 
not from the international agreements that are submitted as 
treaties, however, but from the many international agreements 
that are not submitted for its consent. In addition to 
concluding hundreds of executive agreements, Presidents have 
made important commitments that they considered politically 
binding but not legally binding. Maintaining the Senate role in 
treaties requires overseeing all international agreements to 
assure that agreements that should be treaties are submitted to 
the Senate.

                             A. Background

                  the evolution of the senate role \2\
---------------------------------------------------------------------------

    \2\ See Chapters II and VI for references and additional 
discussion.
---------------------------------------------------------------------------
    The Constitution states that the President ``shall have 
Power, by and with the Advice and Consent of the Senate, to 
make Treaties, provided two-thirds of the Senators present 
concur.'' The Convention that drafted the Constitution did not 
spell out more precisely what role it intended for the Senate 
in the treatymaking process. Most evidence suggests that it 
intended the sharing of the treaty power to begin early, with 
the Senate helping to formulate instructions to negotiators and 
acting as a council of advisers to the President during the 
negotiations, as well as approving each treaty entered into by 
the United States. The function of the Senate was both to 
protect the rights of the states and to serve as a check 
against the President's taking excessive or undesirable actions 
through treaties. The Presidential function in turn was to 
provide unity and efficiency in treatymaking and to represent 
the national interest as a whole.
    The treaty clause of the Constitution does not contain the 
word ratification, which refers to the formal act by which a 
nation affirms its willingness to be bound by a specific 
treaty. From the beginning, the formal act of ratification has 
been performed by the President acting ``by and with the advice 
and consent of the Senate.'' The President ratifies the treaty, 
but, only after receiving the advice and consent of the Senate.
    When the Constitution was drafted, the ratification of a 
treaty was generally considered obligatory by the nations 
entering into it if the negotiators stayed within their 
instructions. Therefore Senate participation during the 
negotiations stage seemed essential if the Senate was to play a 
meaningful constitutional role. At the time, such direct 
participation by the Senate also seemed feasible, since the 
number of treaties was not expected to be large and the 
original Senate contained only 26 Members.
    Within several years, however, problems were encountered in 
treatymaking and Presidents abandoned the practice of regularly 
getting the Senate's advice and consent on detailed questions 
prior to negotiations. Instead, Presidents began to submit the 
completed treaty after its conclusion. Since the Senate had to 
be able to advise changes or deny consent altogether if its 
role was to be meaningful, the doctrine of obligatory 
ratification was for all practical purposes abandoned.
    Although Senators sometimes play a part in the initiation 
or development of a treaty, the Senate role now is primarily to 
pass judgment on whether completed treaties should be ratified 
by the United States. The Senate's advice and consent is asked 
on the question of Presidential ratification. When the Senate 
considers a treaty it may approve it as written, approve it 
with conditions, reject and return it, or prevent its entry 
into force by withholding approval. In practice the Senate 
historically has given its advice and consent unconditionally 
to the vast majority of treaties submitted to it.
    In numerous cases, the Senate has approved treaties subject 
to conditions. The President has usually accepted the Senate 
conditions and completed the ratification process. In some 
cases, treaties have been approved with reservations that were 
unacceptable either to the President or the other party, and 
the treaties never entered into force.\3\
---------------------------------------------------------------------------
    \3\ These include treaties on income taxation with Thailand, signed 
March 1965, and Brazil, signed March 13, 1967.
---------------------------------------------------------------------------
    Only on rare occasions has the Senate formally rejected a 
treaty. The most famous example is the Versailles Treaty, which 
was defeated on March 19, 1920, although 49 Senators voted in 
favor and 35 against. This was a majority but not the required 
two-thirds majority so the treaty failed. Since then, the 
Senate has definitively rejected only three treaties.\4\ In 
addition, the Senate sometimes formally rejects treaties but 
keeps them technically alive by adopting or entering a motion 
to reconsider. This has happened, for instance, with the 
Optional Protocol Concerning the Compulsory Settlement of 
Disputes in 1960, the Montreal Aviation Protocols Nos. 3 and 4 
in 1983, and the Comprehensive Test Ban Treaty in 1999.
---------------------------------------------------------------------------
    \4\ Treaty on General Relations with Turkey, January 18, 1927; St. 
Lawrence Waterway Treaty with Canada, July 18, 1932 (the St. Lawrence 
Seaway was subsequently approved by legislation); and adherence to the 
Permanent Court of International Justice, January 29, 1935.
---------------------------------------------------------------------------
    More often the Senate has simply not voted on treaties that 
did not have enough support for approval, and the treaties 
remained pending in the Foreign Relations Committee for long 
periods. Eventually, unapproved treaties have been replaced by 
other treaties, amended by protocols and then approved, or 
withdrawn by or returned to the President. Thus the Senate has 
used its veto sparingly, but still demonstrated the necessity 
of its advice and consent and its power to block a treaty from 
entering into force.

                  treaties under international law \5\
---------------------------------------------------------------------------

    \5\ See Chapter III for references and additional discussion.
---------------------------------------------------------------------------
    Under international law an international agreement is 
generally considered to be a treaty and binding on the parties 
if it meets four criteria:
    (1) The parties intend the agreement to be legally binding 
and the agreement is subject to international law;
    (2) The agreement deals with significant matters;
    (3) The agreement clearly and specifically describes the 
legal obligations of the parties; and
    (4) The form indicates an intention to conclude a treaty, 
although the substance of the agreement rather than the form is 
the governing factor.
    International law makes no distinction between treaties and 
executive agreements. Executive agreements, especially if 
significant enough to be reported to Congress under the Case-
Zablocki Act, are to all intents and purposes binding treaties 
under international law.\6\
---------------------------------------------------------------------------
    \6\ The Case-Zablocki Act (Public Law 92-403, as amended), is also 
examined in Chapter X. See Appendix 2 for text of the law.
---------------------------------------------------------------------------
    On the other hand, many international undertakings and 
foreign policy statements, such as unilateral statements of 
intent, joint communiques, and final acts of conferences, are 
not intended to be legally binding and are not considered 
treaties.

                      treaties under u.s. law \7\
---------------------------------------------------------------------------

    \7\ See Chapter IV for references and additional discussion. See 
also Chapter X.
---------------------------------------------------------------------------
    Under the Constitution, a treaty, like a Federal statute, 
is part of the ``supreme Law of the Land.'' Self-executing 
treaties, those that do not require implementing legislation, 
automatically become effective as domestic law immediately upon 
entry into force. Other treaties do not become effective as 
domestic law until implementing legislation is enacted, and 
then technically it is the legislation, not the treaty unless 
incorporated into the legislation, that is the law of the land.
    Sometimes it is not clear on the face of a treaty whether 
it is self-executing or requires implementing legislation. Some 
treaties expressly call for implementing legislation or deal 
with subjects clearly requiring congressional action, such as 
the appropriation of funds or enactment of domestic penal 
provisions. The question of whether or not a treaty requires 
implementing legislation or is self-executing is a matter of 
interpretation largely by the executive branch or, less 
frequently, by the courts. On occasion, the Senate includes an 
understanding in the resolution of ratification that certain 
provisions are not self-executing or that the President is to 
exchange or deposit the instrument of ratification only after 
implementation legislation has been enacted.
    When a treaty is deemed self-executing, it overrides any 
conflicting provision of the law of an individual signatory 
state. If a treaty is in irreconcilable conflict with a Federal 
law, the one executed later in time prevails, although courts 
generally try to harmonize domestic and international 
obligations whenever possible.

                executive agreements under u.s. law \8\
---------------------------------------------------------------------------

    \8\ See Chapter IV for references and additional discussion. See 
also Chapter X.
---------------------------------------------------------------------------
    The status in domestic law of executive agreements, that 
is, international agreements made by the executive branch but 
not submitted to the Senate for its advice and consent, is less 
clear. Three types of executive agreements and their domestic 
legal status are discussed below.
(1) Congressional-executive agreements
    Most executive agreements are either explicitly or 
implicitly authorized in advance by Congress or submitted to 
Congress for approval. Some areas in which Congress has 
authorized the conclusion of international agreements are 
postal conventions, foreign trade, foreign military assistance, 
foreign economic assistance, atomic energy cooperation, and 
international fishery rights. Sometimes Congress has authorized 
conclusion of agreements but required the executive branch to 
submit the agreements to Congress for approval by legislation 
or for a specified waiting period before taking effect. 
Congress has also sometimes approved by joint resolution 
international agreements involving matters that are frequently 
handled by treaty, including such subjects as participation in 
international organizations, arms control measures, and 
acquisition of territory. The constitutionality of this type of 
agreement seems well established and Congress has authorized or 
approved them frequently,
(2) Agreements pursuant to treaties
    Some executive agreements are expressly authorized by 
treaty or an authorization for them may be reasonably inferred 
from the provisions of a prior treaty. Examples include 
arrangements and understandings under the North Atlantic Treaty 
and other security treaties. The President's authority to 
conclude agreements pursuant to treaties seems well 
established, although controversy occasionally arises over 
whether particular agreements are within the purview of an 
existing treaty.
(3) Presidential or sole executive agreements
    Some executive agreements are concluded solely on the basis 
of the President's independent constitutional authority and do 
not have an underlying explicit or implied authorization by 
treaty or statute. Authorities from the Constitution that 
Presidents claim as a basis for such agreements include:
  --The President's general executive authority in Article II, 
        Section 1, of the Constitution;
  --His power as Commander in Chief of the Army and Navy in 
        Article II, Section 2, Clause 1;
  --The treaty clause itself for agreements, which might be 
        part of the process of negotiating a treaty in Article 
        II, Section 2, Clause 2;
  --His authority to receive Ambassadors and other public 
        Ministers in Article II, Section 3; and
  --His duty to ``take care that the laws be faithfully 
        executed'' in Article II, Section 3.
    Courts have indicated that executive agreements based 
solely on the President's independent constitutional authority 
can supersede conflicting provisions of state law, but opinions 
differ regarding the extent to which they can supersede a prior 
act of Congress. What judicial authority exists seems to 
indicate that they cannot.

 steps in the u.s. process of making treaties and executive agreements

    Phases in the life of a treaty include negotiation and 
conclusion, consideration by the Senate, Presidential 
ratification, implementation, modification, and termination. 
Following is a discussion of the major steps and the roles of 
the President and the Senate in each phase.
    Executive agreements are negotiated and concluded in the 
same way as treaties, but they do not go through the procedure 
for advice and consent of the Senate. Some executive agreements 
are submitted to the Congress for approval and most are to be 
transmitted to Congress after their conclusion. (See charts 1 
and 2.)
Negotiation and conclusion \9\
---------------------------------------------------------------------------
    \9\ See Chapter V for references and additional discussion.
---------------------------------------------------------------------------
    The first phase of treatymaking, negotiation and 
conclusion, is widely considered an exclusive prerogative of 
the President except for making appointments which require the 
advice and consent of the Senate. The President chooses and 
instructs the negotiators and decides whether to sign an 
agreement after its terms have been negotiated. Nevertheless, 
the Senate or Congress sometimes proposes negotiations and 
influences them through advice and consultation. In addition, 
the executive branch is supposed to advise appropriate 
congressional leaders and committees of the intention to 
negotiate significant new agreements and consult them as to the 
form of the agreement.
    Steps in the negotiating phase follow.
    (1) Initiation.--The executive branch formally initiates 
the negotiations. The original concept or proposal for a treaty 
on a particular subject, however, may come from Congress.
    (2) Appointment of negotiators.--The President selects the 
negotiators of international agreements, but appointments may 
be subject to the advice and consent of the Senate. 
Negotiations are often conducted by ambassadors or foreign 
service officers in a relevant post who have already been 
confirmed by the Senate.
    (3) Issuance of full powers and instructions.--The 
President issues full power documents to the negotiators, 
authorizing them officially to represent the United States. 
Similarly, he issues instructions as to the objectives to be 
sought and positions to be taken. On occasion the Senate 
participates in setting the objectives during the confirmation 
process, or Congress contributes to defining the objectives 
through hearings or resolutions.
    (4) Negotiation.--Negotiation is the process by which 
representatives of the President and other governments 
concerned agree on the substance, terms, wording, and form of 
an international agreement. Members of Congress sometimes 
provide advice through consultations arranged either by 
Congress or the executive branch, and through their statements 
and writings. Members of Congress or their staff have served as 
members or advisers of delegations and as observers at 
international negotiations.
    (5) Conclusion.--The conclusion or signing marks the end of 
the negotiating process and indicates that the negotiators have 
reached agreement. In the case of a treaty the term 
``conclusion'' is a misnomer in that the agreement does not 
enter into force until the exchange or deposit of 
ratifications. In the case of executive agreements, however, 
the signing and entry into force are frequently simultaneous.
Consideration by the Senate \10\
---------------------------------------------------------------------------
    \10\ See Chapter VI for references and additional discussion. 
Chapter VI also contains the text of Senate Rule XXX.
---------------------------------------------------------------------------
    A second phase begins when the President transmits a 
concluded treaty to the Senate and the responsibility moves to 
the Senate. Following are the main steps during the Senate 
phase.
    (1) Presidential submission.--The Secretary of State 
formally submits treaties to the President for transmittal to 
the Senate. A considerable time may elapse between signature 
and submission to the Senate, and on rare occasions a treaty 
signed on behalf of the United States may never be submitted to 
the Senate at all and thus never enter into force for the 
United States. When transmitted to the Senate, treaties are 
accompanied by a Presidential message consisting of the text of 
the treaty, a letter of transmittal requesting the advice and 
consent of the Senate, and the earlier letter of submittal of 
the Secretary of State which usually contains a detailed 
description and analysis of the treaty.
    (2) Senate receipt and referral.--The Parliamentarian 
transmits the treaty to the Executive Clerk, who assigns it a 
document number. The Majority Leader then, as in executive 
session, asks the unanimous consent of the Senate that the 
injunction of secrecy be removed, that the treaty be considered 
as having been read the first time, and that it be referred to 
the Foreign Relations Committee and ordered to be printed. The 
Presiding Officer then refers the treaty, regardless of its 
subject matter, to the Foreign Relations Committee in 
accordance with Rule XXV of the Senate Rules. (Rule XXV makes 
an exception only for reciprocal trade agreements.) At this 
point the treaty text is printed and made available to the 
public.
    (3) Senate Foreign Relations Committee action.--The treaty 
is placed on the committee calendar and remains there until the 
committee reports it to the full Senate. While it is committee 
practice to allow a treaty to remain pending long enough to 
receive study and comments from the public, the committee 
usually considers a treaty within a year or two, holding a 
hearing and preparing a written report.
    The committee recommends Senate advice and consent by 
reporting a treaty with a proposed resolution of ratification. 
While most treaties have historically been reported without 
conditions, the committee may recommend that the Senate approve 
a treaty subject to conditions incorporated in the resolution 
of ratification.
    (4) Conditional approval.--The conditions traditionally 
have been grouped into categories described in the following 
way.
  --Amendments to a treaty change the text of the treaty and 
        require the consent of the other party or parties. 
        (Note that in Senate debate the term may refer to an 
        amendment of the resolution of ratification, not the 
        treaty itself, and therefore be comprised of some other 
        type of condition.)

        [GRAPHIC] [TIFF OMITTED] T6922.002
        
        [GRAPHIC] [TIFF OMITTED] T6922.003
        
  --Reservations change U.S. obligations without necessarily 
        changing the text, and they require the acceptance of 
        the other party.
  --Understandings are interpretive statements that clarify or 
        elaborate provisions but do not alter them.
  --Declarations are statements expressing the Senate's 
        position or opinion on matters relating to issues 
        raised by the treaty rather than to specific 
        provisions.
  --Provisos relate to issues of U.S. law or procedure and are 
        not intended to be included in the instruments of 
        ratification to be deposited or exchanged with other 
        countries.
    Whatever name a condition is given by the Senate, if a 
condition alters an international obligation under the treaty, 
the President is expected to transmit it to the other party. In 
recent years, the Senate on occasion has explicitly designated 
that some conditions were to be transmitted to the other party 
or parties and, in some cases, formally agreed to by them. It 
has also designated that some conditions need not be formally 
communicated to the other party, that some conditions were 
binding on the President, and that some conditions expressed 
the intent of the Senate.
    (5) Action by the full Senate.--After a treaty is reported 
by the Foreign Relations Committee, it is placed on the 
Senate's Executive Calendar and the Majority Leader arranges 
for the Senate to consider it. In 1986 the Senate amended Rule 
XXX of the Senate Rules, which governs its consideration of 
treaties, to simplify the procedure in this step. Still, under 
the full procedures of the revised Rule XXX, in the first stage 
of consideration the treaty would be read a second time and any 
proposed amendments to the treaty itself would be considered 
and voted upon by a simple majority. Usually the Majority 
Leader obtains unanimous consent to abbreviate the procedures, 
and the Senate proceeds directly to the consideration of the 
resolution of ratification as recommended by the Foreign 
Relations Committee.
    The Senate then considers amendments to the resolution of 
ratification, which would incorporate any amendments to the 
treaty itself that the Senate had agreed to in the first stage, 
as well as conditions recommended by the Foreign Relations 
Committee. Senators may then offer reservations, 
understandings, and other conditions to be placed in the 
resolution of ratification. Votes on these conditions, as well 
as other motions, are determined by a simple majority. Finally, 
the Senate votes on the resolution of ratification, as it has 
been amended. The final vote on the resolution of ratification 
requires, for approval, a two-thirds majority of the Senators 
present. Although the number of Senators who must be present is 
not specified, the Senate's practice with respect to major 
treaties is to conduct the final treaty vote at a time when 
most Senators are available. After approval of a controversial 
treaty, a Senator may offer a motion to reconsider which is 
usually laid on the table (defeated). In the case of a treaty 
that has failed to receive a two-thirds majority, if the motion 
to reconsider is not taken up, the treaty is returned to the 
Foreign Relations Committee. Prior to the final vote on the 
resolution of ratification, a Senator may offer a substitute 
amendment, proposing that the Senate withhold its advice and 
consent, or offer a motion to recommit the resolution to the 
Foreign Relations Committee.
    (6) Return to committee.--Treaties reported by the 
committee but neither approved nor formally returned to the 
President by the Senate are automatically returned to the 
committee calendar at the end of a Congress; the committee must 
report them out again in order for the Senate to consider them.
    (7) Return to President or withdrawal.--The President may 
request the return of a treaty, or the Foreign Relations 
Committee may report and the Senate adopt a simple resolution 
directing the Secretary of the Senate to return a treaty to the 
President. Otherwise, treaties that do not receive the advice 
and consent of the Senate remain pending on the committee 
calendar indefinitely.
Presidential action after Senate action \11\
---------------------------------------------------------------------------
    \11\ See Chapter VII for references and additional discussion.
---------------------------------------------------------------------------
    After the Senate gives its advice and consent to a treaty, 
the Senate sends it to the President. He resumes control and 
decides whether to take further action to complete the treaty.
    (1) Ratification.--The President ratifies a treaty by 
signing an instrument of ratification, thus declaring the 
consent of the United States to be bound. If the Senate has 
consented with reservations or conditions that the President 
deems unacceptable, he may at a later date resubmit the 
original treaty to the Senate for further consideration, or he 
may renegotiate it with the other parties prior to 
resubmission. Or the President may decide not to ratify the 
treaty because of the conditions or for any other reason.
    (2) Exchange or deposit of instruments of ratification and 
entry into force.--If he ratifies the treaty, the President 
then directs the Secretary of State to take any action 
necessary for the treaty to enter into force. A bilateral 
treaty usually enters into force when the parties exchange 
instruments of ratification. A multilateral treaty enters into 
force when the number of parties specified in the treaty 
deposit the instruments of ratification at a specified 
location. Once a treaty enters into force, it is binding in 
international law on the parties who have ratified it.
    (3) Proclamation.--When the instruments of ratification 
have been exchanged or the necessary number deposited, the 
President issues a proclamation that the treaty has entered 
into force. Proclamation serves as legal notice for domestic 
purposes and publicizes the text.
Implementation \12\
---------------------------------------------------------------------------
    \12\ See Chapter VIII for references and additional discussion.
---------------------------------------------------------------------------
    The executive branch has the primary responsibility for 
carrying out treaties and ascertaining that other parties 
fulfill their obligations after treaties and other 
international agreements enter into force, but the Senate or 
the entire Congress share in the following phases.
    (1) Implementing legislation.\13\--When implementing 
legislation or appropriations are needed to carry out the terms 
of a treaty, it must go through the full legislative process 
including passage by both Houses and presentment to the 
President.
---------------------------------------------------------------------------
    \13\ In addition to Chapter VIII, see Chapter X.
---------------------------------------------------------------------------
    (2) Interpretation.\14\--The executive branch interprets 
the requirements of an agreement as it carries out its 
provisions. U.S. courts may also interpret a treaty's effect as 
domestic law in appropriate cases. The Senate has made clear 
that the United States is to interpret the treaty in accordance 
with the common understanding of the treaty shared by the 
President and the Senate at the time the Senate gave its advice 
and consent. This common understanding is based on the text of 
the treaty, the provisions of the resolution of ratification, 
and the authoritative representations provided by the executive 
branch to the Senate during its consideration. The Senate has 
further specified that the United States is not to agree to or 
adopt an interpretation different from the common understanding 
except pursuant to Senate advice and consent or enactment of a 
statute.
---------------------------------------------------------------------------
    \14\ In addition to Chapter VIII, see Chapter VI, and discussion of 
INF Treaty in Chapter XI.
---------------------------------------------------------------------------
    (3) Settlement of international disputes.--When disputes 
arise between parties on the interpretation of a treaty or on 
the facts relating to compliance with the obligations of a 
treaty, the executive branch usually conducts negotiations 
aimed at resolving differences in interpretation. Treaties 
sometimes provide for formal procedures or mechanisms for 
dispute settlement. Members of Congress have sometimes played 
an important role by overseeing implementation of a treaty, 
bringing about public discussion of compliance issues, and 
urging procedures to resolve international disputes.
Modification, extension, suspension, or termination \15\
---------------------------------------------------------------------------
    \15\ See Chapter IX for references and additional discussion.
---------------------------------------------------------------------------
    Modifying and extending an international agreement amount 
to the making of a new agreement that should be done by the 
same method as the original agreement. For treaties, this means 
with the advice and consent of the Senate. Practice on 
termination, however, has not been consistent.
    (1) Modification.--At the international level, treaties are 
amended by agreement of the parties or in accordance with their 
terms. In the United States, amendments to treaties are 
ordinarily submitted to the Senate for its advice and consent, 
unless the treaty provides for modification in some other way. 
Less formal modifications have been made by executive 
agreements or decisions.
    (2) Extension.--An agreement to extend an existing 
international agreement is considered a new agreement, and 
ordinarily would be accomplished in the same fashion as the 
original, with an extension of a treaty submitted to the 
Senate.
    (3) Suspension.--The President conveys notice of suspension 
of a treaty and makes the determination that would justify 
suspension, such as a fundamental change in circumstances or 
material breach of a treaty by another party.
    (4) Termination.--At the international level, treaties 
often contain provisions regarding duration and the method of 
termination, or nations may terminate treaties by mutual 
consent. Grounds for termination include violation of the 
agreement, but violation does not automatically terminate a 
treaty.
    Domestically, the Constitution does not prescribe the 
process for the United States to terminate a treaty, and the 
process continues to be controversial. Treaties have been 
terminated in a variety of ways, including by the President 
following a joint resolution of Congress, by the President 
following action by the Senate, by the President and with 
subsequent congressional or Senate approval, and by the 
President alone.
Congressional oversight \16\
---------------------------------------------------------------------------
    \16\ See Chapter X for references and additional discussion.
---------------------------------------------------------------------------
    Congress has responsibility for overseeing the negotiation 
and conclusion of international agreements by the executive 
branch and the manner in which the executive branch interprets 
and carries out the agreements. It shares with the executive 
branch the responsibility for assessing the general 
effectiveness of international agreements at the international 
level and determining the course of action when agreements are 
not effective.
    (1) Hearings and reports.--Congress reviews actions under 
treaties and other international agreements as part of its 
responsibilities for overseeing executive branch activities. 
Senate and House rules direct committees to review the 
application of those laws within their jurisdiction, so the 
oversight function is distributed widely among the various 
committees of Congress. Methods for oversight include hearings, 
investigations, consultations, and requiring and reviewing 
reports.
    (2) Review of executive agreements.--Under the Case-
Zablocki Act, all executive agreements are to be transmitted to 
Congress within 60 days of their entry into force, including 
those that are classified for security reasons. The receipt is 
noted in the Congressional Record, and unclassified agreements 
are listed in committee publications. Members of Congress may 
read the agreements in the Senate Foreign Relations and House 
Foreign Affairs Committee offices.

                trends in senate action on treaties \17\
---------------------------------------------------------------------------

    \17\ See Chapter VI and Chapter XI for references and additional 
discussion.
---------------------------------------------------------------------------
    In recent years the Senate has endeavored both to improve 
its efficiency in handling treaties and to assure a meaningful 
role. Among steps to streamline procedures, in 1986 it amended 
Senate Rule XXX to eliminate the requirement for consideration 
by the Senate as in Committee of the Whole. It has frequently 
approved groups of treaties with a single roll call vote, or 
approved treaties by a division vote. The Senate Legis computer 
system has made it easier for Senators to obtain current 
information on action on treaties before the Senate.
    Among steps to assure a meaningful role, the Senate has 
appointed observer groups to negotiations on important 
treaties, especially in the arms control and environmental 
areas. In 1987 and 1988 the Senate reviewed the constitutional 
principles of treaty interpretation and affirmed that the 
United States should not agree to or adopt an interpretation 
different from the common understanding shared by the President 
and the Senate at the time the Senate gave its advice and 
consent to ratification, except pursuant to Senate advice and 
consent or enactment of a statute. The Senate also provided a 
system to review the negotiating record of the Intermediate 
Range Nuclear Forces (INF) Treaty. However, the Foreign 
Relations Committee said that Senate review of negotiating 
records should not become an institutionalized procedure, but 
that reference to the record on a case-by-case basis might 
sometimes be useful.
    Treaties and Senate action on them have begun to reflect 
new policy concerns since the end of the Cold War. Increased 
recognition has been given to the importance of economic 
treaties, including consular, investment, and tax agreements. 
The use of friendship, commerce, and navigation (FCN) treaties 
decreased after 1948 when the United States entered the General 
Agreement on Tariffs and Trade (GATT). Since investment matters 
were outside the scope of GATT at that time, in 1981 the United 
States began to negotiate a series of bilateral investment 
treaties (BITs). Subsequently, the Senate has given its advice 
and consent to BITs with several countries.
    Treaties providing for cooperation in bringing suspected 
criminals to trial have become increasingly important with the 
growth of transnational criminal activity, including narcotics 
trafficking, terrorism, money laundering, and export control 
violations. The two chief types are extradition treaties and a 
new series called mutual legal assistance treaties (MLATs). The 
Senate Foreign Relations Committee has supported recent 
supplementary extradition treaties and new MLATs, although 
sometimes with conditions.
    Treaties for conservation of certain species of wildlife 
and regulation of fisheries have been supplemented with broad 
treaties for environmental cooperation. Although supportive of 
environmental cooperation treaties, the Senate Foreign 
Relations Committee has expressed concern about articles 
prohibiting reservations and has cautioned that consent to 
three multilateral environmental treaties containing such 
articles should not be construed as a precedent.

         B. Issues in Treaties Submitted for Advice and Consent

    Although it can prevent a treaty from being ratified or 
attach conditions for ratification, the Senate frequently finds 
it difficult to advise on treaties effectively. Several 
obstacles to a meaningful Senate role have developed.

           request for consent without opportunity for advice

    A major problem derives from the executive branch practice 
of not submitting a treaty to the Senate until it is completed. 
Seeing the terms of the treaty only after it has been signed, 
the Senate frequently has little choice in practice except to 
consent to a treaty exactly as it has been negotiated, or to 
block it entirely. The President may present a treaty as vital 
to good relations with a nation, relations that would be set 
back immeasurably if the treaty were defeated. Or he may 
present it as a package that has been so delicately negotiated 
that the slightest change in understanding by the Senate would 
unbalance the package and kill the treaty. Or he may present it 
so late in the congressional session, or so near some type of 
international deadline, that Senate consideration in depth is 
pictured as impeding the beginning of a new beneficial regime.
    Administrations almost always discourage significant 
changes that might require renegotiation of a treaty, and the 
Senate usually defeats attempted reservations that would 
actually alter treaty obligations. Rather than adding 
reservations or attempting to amend the treaty itself, the 
Senate often addresses its concerns through understandings that 
do not alter the obligations under the treaty and therefore do 
not require renegotiation.
    The Senate has the choice of rejecting a treaty by a public 
vote, or by quietly not bringing the treaty to a vote. In 
recent years it has almost always chosen not to conduct a vote 
that might embarrass the U.S. negotiators, make the United 
States appear divided, and impair relations with other 
countries. In either event, Senate defeat of a treaty entails a 
loss of the time, energy, and in some cases U.S. international 
prestige invested in the negotiations.
    An option for avoiding defeats is legislative-executive 
consultation prior to or during negotiations. The President can 
initiate consultation through meetings or by inviting 
congressional observers to negotiations. The Senate can 
initiate consultation through hearings and other meetings or 
through resolutions or legislative directives. In the past, 
some Senators have been concerned that participating in the 
formulation of a treaty could pose a conflict of interest since 
Senators are subsequently asked to pass judgment on the 
completed treaty. With the increase in multilateral treaties 
and other developments, this concern appears to have 
diminished.

                         multilateral treaties

    The Senate's problem of not receiving a treaty until it is 
completed is particularly acute in multilateral treaties. These 
treaties are often negotiated by many nations in large 
international conferences, sometimes over a period of years. 
States make concessions in one area to obtain concessions from 
other states in other areas. The result is often an interwoven 
package that the Senate is called upon to take or leave in its 
entirety, without amendments or reservations, because 
renegotiation may not be feasible.
    Some multilateral treaties have contained an article 
prohibiting reservations. The Senate Foreign Relations 
Committee has taken the position that the executive branch 
negotiators should not agree to this prohibition. The Senate 
has given its advice and consent to a few treaties containing 
the prohibition, but the committee has stated that approval of 
these treaties should not be construed as a precedent for such 
clauses in future treaties. It has further stated that the 
President's agreement to such a clause could not constrain the 
Senate's right and obligation to attach reservations to its 
advice and consent.\18\
---------------------------------------------------------------------------
    \18\ See section on Environmental Treaties in Chapter XI.
---------------------------------------------------------------------------
    A related problem arises from reservations made by other 
nations to a multilateral treaty. Although the reservations may 
modify international obligations, the Department of State has 
not been sending the reservations to the Senate for its advice 
and consent. It has been assumed that the Senate, aware of this 
practice, tacitly consents to the U.S. acceptance of the 
reservations.\19\ Without information on the reservations, 
however, the Senate cannot estimate the size or significance of 
the problem.
---------------------------------------------------------------------------
    \19\ See section on Amendment in Chapter IX.
---------------------------------------------------------------------------
    The trend toward more multilateral agreements seems 
inevitable. The United States entered virtually no multilateral 
agreements until the late 1800s, but after 1900 multilateral 
treaties steadily increased and their subject coverage 
expanded. From 1980 through 1991 the United States entered 259 
multilateral agreements of which 79 were treaties. For the 
future, with the number of sovereign nations still growing, 
multilateral agreements on a subject offer an efficient 
alternative to bilateral agreements with 100 or 200 countries.
    The great increase in multilateral diplomacy and 
multilateral agreements is introducing another new phenomenon. 
The United States now has bilateral international agreements 
with approximately 50 international organizations. It might 
appear that the Senate would encounter the same difficulty in 
proposing modifications it does in the case of multilateral 
agreements. Renegotiation of bilateral treaties with 
multilateral organizations should be more feasible, however, 
because the United States is one of only two negotiating 
partners. Moreover, the United States is in most instances also 
a major player in the international organization, the other 
negotiating partner.

    diminishing use of treaties for major political commitments \20\
---------------------------------------------------------------------------

    \20\ See Chapter XI for references and additional discussion.
---------------------------------------------------------------------------
    At the end of World War II, treaties played an important 
part in shaping post-war U.S. foreign policy. Formal peace 
treaties were concluded with all belligerents except Germany. 
The Charters of the United Nations and the Organization of 
American States established a framework for international 
cooperation. The North Atlantic Treaty and other regional 
security treaties built a network of mutual security that 
endured throughout the Cold War.
    After 1955 the building of commitments through treaties 
appeared to halt, and many in Congress expressed concern with 
commitments made through executive action. In 1969 the Senate 
adopted the National Commitments Resolution expressing the 
sense that a national commitment ``results only from 
affirmative action taken by the executive and legislative 
branches of the U.S. Government by means of a treaty, statute, 
or concurrent resolution of both Houses of Congress 
specifically providing for such commitment.'' Yet for the rest 
of the Cold War, military and security commitments were not 
made as treaties but as executive agreements, non-binding 
political agreements, or unilateral executive branch statements 
and actions.
    Arms control treaties became the only type of agreement in 
the political-military field that have been concluded primarily 
in treaty form. In this area legislation specified that 
agreements be concluded as treaties or authorized by 
legislation, and the Senate insisted that most agreements be 
submitted as treaties. As a result, arms control treaties have 
been the main vehicle in recent years for special Senate 
influence on foreign policy.
    The end of the Cold War offers a new era in foreign policy 
comparable to that which existed at the end of World War II. As 
the agreements to provide the framework for the new era are 
concluded, the significance of the Senate's treaty power is 
again being tested. Some agreements to shape the new foreign 
policy already have been undertaken by executive agreement, 
non-binding political agreement, or unilateral executive branch 
statements or actions. In other cases, the Senate has insisted 
that agreements be concluded as treaties. Such insistence 
appears to have become necessary to ensure that significant 
political agreements are submitted as treaties.

    unilateral executive branch action to reinterpret, modify, and 
                           terminate treaties

    The Constitution is silent on procedures for modifying or 
terminating treaties, and agreement has not been reached 
between the branches on a single proper mode.\21\ The general 
rule is that international agreements are to be amended in the 
same way that they were made, thus for treaties requiring the 
advice and consent of the Senate. With the increase in numbers 
and complexity of treaties, more frequent changes and 
adjustments have become necessary. The Senate has again been 
challenged to be vigilant for unilateral executive branch 
action that might change a basic obligation agreed to in its 
advice and consent to a treaty.
---------------------------------------------------------------------------
    \21\ See Chapter IX for references and additional discussion.
---------------------------------------------------------------------------
    What portion of treaty modifications have been submitted to 
the Senate is unknown. Although certain changes have been 
routinely submitted to the Senate, such as amendments to tax 
treaties, others have been made solely by executive agreement 
or action. The most controversial unilateral action of the 
executive branch in recent years involved reinterpretation of 
the Anti-Ballistic Missile (ABM) Treaty of 1972. In 1985, the 
Reagan Administration sought to reinterpret the ABM Treaty to 
permit development of mobile space-based anti-ballistic systems 
for the Strategic Defense Initiative. The Senate became 
concerned about both the future of the ABM Treaty and the 
failure to obtain its advice and consent for a major change in 
treaty obligations. It attached a condition to the INF Treaty 
restating the principle that the President may not adopt a 
treaty interpretation different from the common understanding 
shared by the Senate at the time it gave its advice and 
consent, without the advice and consent of the Senate or the 
enactment of a statute. In action on subsequent arms control 
treaties, the Senate affirmed the applicability of these 
principles to all treaties. In 1993 the Clinton Administration 
made clear it had returned to the ``narrow'' or ``traditional'' 
interpretation of the ABM Treaty.\22\
---------------------------------------------------------------------------
    \22\ See Chapters VI, VIII, and IX for references and additional 
discussion.
---------------------------------------------------------------------------
    Twice in recent years the method of terminating a treaty 
has raised serious controversy within the United States. In 
1978, President Carter terminated the defense treaty with the 
Republic of China without the concurrence of either the Senate 
or Congress when he established diplomatic relations with the 
People's Republic of China. In 1977, the new Panama Canal 
Treaty terminated the 1903, 1936, and 1955 treaties with 
Panama. Although a new treaty was approved by the Senate, some 
contended that the termination of the earlier treaties required 
an act of Congress, thus including approval by the House of 
Representatives as well as the Senate.

                 difficulty in overseeing treaties \23\
---------------------------------------------------------------------------

    \23\ See Chapter X for references and additional discussion.
---------------------------------------------------------------------------
    Once it has given its advice and consent to a treaty, the 
Senate often lacks the information necessary to oversee further 
action under the treaty. It does not receive a copy of the 
resolution of ratification signed by the President, or the 
proclamation, to enable comparison with the resolution of 
ratification adopted by the Senate. It does not receive copies 
of reservations or conditions established by other parties, to 
enable a determination of whether the advice and consent of the 
Senate should have been required. It is not always informed 
when a treaty has entered into force or been modified in some 
way. Completion by the Department of State of a computerized 
information system on treaties, with Senate access, might 
enable the Senate to oversee some aspects of the implementation 
of treaties more effectively.
    Compliance with treaties has also become an issue on some 
occasions, especially in the arms control field. Oversight of 
compliance has been done with traditional congressional tools 
such as hearings, investigations, and required reports.

                             minority power

    Questions are sometimes raised because of the power of a 
minority to block a treaty. Since a two-thirds majority of the 
Senators present is required to advise and consent to a treaty, 
a minority of one-third plus one of the Senate may reject a 
treaty. In some cases Senators in the minority seem to have 
more influence on a treaty or the substance of future policy 
than other Senators because those in the minority can win 
concessions. The President may be certain of the support of a 
simple majority; he must make special concessions to win the 
extra votes necessary for a two-thirds majority. Nevertheless, 
a two-thirds majority was clearly the intention of the Framers 
of the Constitution, and any formal change would require a 
constitutional amendment.

                       the house role in treaties

    Because treaties become part of the law of the land, 
concern is sometimes expressed that the House of 
Representatives does not share in the treaty power. The Framers 
confined the treatymaking power to the President and the Senate 
in the belief that the latter's smaller size would enable it to 
be a confidential partner in the negotiations. The need for 
maintaining secrecy during negotiations and acting with speed 
were also cited as justifications for not including the House. 
In addition, by making the treaty power a national power and 
requiring the advice and consent of the Senate, the Framers 
gave expression to their desire to form a strong central 
government while affording the states ample safeguards.
    The Supreme Court, in INS v. Chadha, cited the Senate's 
power to advise and consent to treaties negotiated by the 
President ``as one of only four provisions in the Constitution, 
explicit and unambiguous, by which one House may act alone with 
the unreviewable force of law, not subject to the President's 
veto.'' \24\ In 1945 the House adopted a resolution to amend 
the Constitution to require the advice and consent of both 
Houses for treaties, but the Senate did not act on the 
measure.\25\

    The House from the beginning has played a role in treaties 
that require implementing legislation. On occasion, as in 1796 
with the Jay Treaty, problems have arisen when Presidents have 
completed ratification of treaties and then called upon 
Congress to pass implementing legislation to prevent the United 
States from defaulting on its international obligations. 
Treaties approved by the Senate have sometimes remained 
unfulfilled for long periods because implementing legislation 
was not passed.
    The increasing use of congressional-executive agreements 
has also equalized to some extent the role of the House vis-a-
vis the Senate in the making of international agreements. 
Executive agreements authorized or approved by legislation give 
a majority in the House and Senate the power analogous to the 
Senate's advice and consent by a two-thirds majority.

                vienna convention on the law of treaties

    A pending issue for the Senate is what action to take on 
the Vienna Convention on the Law of Treaties, a codification of 
the international law of treaties which is increasingly cited 
as a source of international law, even though the United States 
has not yet ratified it. The United States played a leading 
role in negotiating the Vienna Convention at a conference of 
more than 100 nations and signed it with almost 50 other 
countries on May 23, 1969. As in the case of many treaties, 
however, the executive branch conducted the negotiations 
without congressional observers or consultations, although the 
subject matter was of clear concern to the Senate.
    The convention was signed by the United States on May 23, 
1969, and submitted to the Senate on November 7, 1971. The 
Senate Foreign Relations Committee ordered reported a 
resolution of advice and consent to ratification, subject to an 
understanding and an interpretation, on September 7, 1972, but 
the Department of State and the Senate Foreign Relations 
Committee could not agree on acceptable conditions and the 
convention remains pending on the Foreign Relations Committee 
calendar.\26\
---------------------------------------------------------------------------
    \26\ See section on the Vienna Convention on the Law of Treaties in 
Chapter III. The text of the Vienna Convention is contained in Appendix 
5.
---------------------------------------------------------------------------
    The main dilemma is that simple ratification would leave 
unresolved important constitutional issues relating to 
executive agreements. The Vienna Convention codifies an 
international law definition of treaties that makes no 
distinction between different forms of international 
agreements. Article 46 permits a state to invalidate a treaty 
if a violation of domestic law in concluding the treaty was 
``manifest and concerned a rule of its internal law of 
fundamental importance.'' In 1972, however, the Department of 
State objected to the interpretation proposed by the Senate 
Foreign Relations Committee that it was ``a rule of internal 
law of the United States of fundamental importance'' that no 
treaty as defined by the convention would be valid unless it 
had received the advice and consent of the Senate or its terms 
had been approved by law.
    The second problem is that, although the United States has 
traditionally supported the progressive codification of 
international law, in a few instances the Vienna Convention 
formally codifies rules of international law that may not have 
been fully accepted as customary law by the United States. In 
particular, the Vienna Convention provides that an 
international agreement is void if it conflicts with a 
fundamental norm of general international law ``accepted and 
recognized by the international community of States as a whole 
as a norm from which no derogation is permitted * * *.'' The 
United States in principle does not object to this concept 
known as jus cogens, but the convention does not state by whom 
or how such norms are established.
    Furthermore, the Vienna Convention provides that if a 
treaty dispute relating to jus cogens is not resolved within 12 
months, any party may invoke the jurisdiction of the 
International Court of Justice unless the parties agree to 
submit it to arbitration. While the United States has entered a 
number of treaties providing for submission of disputes to the 
International Court of Justice, unqualified Senate approval of 
the Vienna Convention would appear to broaden significantly 
U.S. acceptance of the court's jurisdiction, a matter which has 
long been controversial. The United States withdrew its 
declaration accepting the court's compulsory jurisdiction on 
October 7, 1985. Moreover, in approving some treaties with 
provisions for submission of disputes to the International 
Court of Justice, the Senate has added conditions. In giving 
its advice and consent to the Genocide Convention, the Senate 
added a reservation that before any dispute to which the United 
States was a party could be submitted to the jurisdiction of 
the International Court of Justice, the specific consent of the 
United States was required in each case.

          C. Issues in Agreements Not Submitted to the Senate

    Any problems the Senate has in influencing treaties pale in 
comparison with problems in influencing many other 
international agreements entered into by the United States. For 
sole executive agreements, many executive agreements entered 
into under the authority of a treaty, and non-legally binding 
or political agreements, the Senate (and Congress as a whole) 
often have little timely knowledge and no opportunity to change 
them or prevent them from taking effect. An exception is the 
category of congressional-executive agreements that are 
authorized by Congress in legislation with procedures for 
congressional review and approval. The problem is one of both 
quantity and quality. The number of agreements not submitted to 
the Senate as treaties has risen sharply while the number of 
treaties has remained steady. At the same time, the subject 
matter coverage of executive agreements has expanded and their 
significance increased.

              increasing use of executive agreements \27\
---------------------------------------------------------------------------

    \27\ See Chapter II for references and additional discussion.
---------------------------------------------------------------------------
    As the United States became more involved in world affairs, 
international agreements multiplied. Most of the growth was in 
executive agreements. The executive branch found it was much 
easier to conclude an executive agreement than a treaty because 
it was not submitted to the Senate. (Compare charts 1 and 2 
above.) The Senate, too, accepted executive agreements as an 
alternate method of making many international agreements, since 
submitting all agreements to the Senate as treaties would 
either overwhelm the Senate with work or force approval to 
become perfunctory.
    Of most concern to the Senate were executive agreements 
concluded solely on the President's own authority, without any 
influence from Congress. In other executive agreements, the 
Senate played a role anyway. In the case of executive 
agreements concluded under the authority of a treaty, the 
Senate consented to the original treaty. In the case of 
congressional-executive agreements, both Houses passed the 
legislation that authorized, required scrutiny of, or approved 
the agreements.

     oversight of executive agreements--the case-zablocki act \28\
---------------------------------------------------------------------------

    \28\ See Chapter X for references and additional discussion. The 
text of the Case-Zablocki Act is contained in Appendix 2.
---------------------------------------------------------------------------
    To help in oversight of executive agreements, in 1972 the 
Case-Zablocki Act was enacted. This Act (1 U.S.C. 112b), 
usually referred to as the Case Act, requires the Secretary of 
State to transmit to Congress all executive agreements, 
including oral agreements which are to be reduced to written 
form, within 60 days after their entry into force. If the 
President deems that the immediate disclosure of an agreement 
would be prejudicial to national security, the agreement is to 
be transmitted to the Senate Foreign Relations and House 
International Relations Committees with a security 
classification.
    The Case Act has proved helpful in informing Congress of 
executive agreements and has provided machinery for additional 
oversight. If fully complied with by the executive branch and 
utilized by Members of Congress, a system exists for Congress 
to learn of executive agreements and to determine the adequacy 
of their authorization.

                    learning of executive agreements

    The first problem dealt with by the Case Act was 
determining when executive agreements have been concluded. In 
the past, Presidents have entered into agreements secretly, as 
evidenced by the Yalta Agreement of 1945 and the Cuban missile 
crisis of 1962. The Case Act requires the State Department to 
send Congress copies of executive agreements. In most cases the 
agreements are submitted within the required 60 days after 
their entry into force, but some are submitted late. While the 
fact that the agreements have already entered into force means 
that Congress cannot prevent them from taking effect, timely 
knowledge does permit Congress an opportunity to consider the 
policy represented by the agreement and to use legislative 
means to modify the policy if it wishes.
    The Case Act has also helped the Department of State, as 
well as Congress, learn of and have some supervision over 
agreements made by agencies of the Government other than the 
State Department. The Case Act requires any department or 
agency that enters an international agreement to transmit the 
agreement to the Department of State within 20 days. In 
addition, it prohibits any international agreement from being 
signed or otherwise concluded on behalf of the United States 
without prior consultation with the Secretary of State. Such 
consultation may cover a class of agreements rather than each 
individual agreement.
    U.S. agencies frequently make contracts and arrangements 
with agencies in other countries. The Secretary of State 
determines for the executive branch whether an arrangement 
constitutes an international agreement required to be 
transmitted to Congress under the Case Act. Members and 
committees of Congress do not want to be deluged with trivia, 
yet they want to be sure to receive important agreements. One 
decision taken to this end by the Secretary of State with 
congressional concurrence was to exclude agreements made by the 
Agency for International Development to provide funds of less 
than $25 million for a foreign project, unless the agreement 
was otherwise significant.

             determining authority for executive agreements

    A basic concern of the Senate has been whether an executive 
agreement is properly within the authority of a treaty or 
statute. In 1973, in implementing the Case Act, the Department 
of State agreed to send with each executive agreement 
transmitted to Congress a background statement on the agreement 
that would include a precise citation of legal authority. 
Checking these citations could help the Senate distinguish 
between those agreements that are within the authority of a 
treaty or statute and those it would consider sole executive 
agreements. In recent years, however, a majority of agreements 
have been transmitted without such background statements.

               non-binding international agreements \29\
---------------------------------------------------------------------------

    \29\ See Chapters III and X for references and additional 
discussion.
---------------------------------------------------------------------------
    Some international agreements are not intended to be 
legally binding, and these non-binding agreements may escape 
regular congressional oversight procedures. Sometimes called 
political agreements, these agreements are not considered 
treaties under international law. They are not enforceable in 
courts, and rules concerning compliance, modification, and 
withdrawal from treaties do not apply. Nevertheless, these 
agreements may be considered morally binding by the parties, 
and the President may be making a type of national commitment 
when he enters one. Moreover such agreements are occasionally 
later converted into legally binding agreements.
    Non-binding agreements are not new. Presidents have often 
made mutual declarations and agreed on final acts and 
communiques after international meetings. Recently some non-
binding agreements appear to have become quite formal, however, 
assuming all the characteristics of a treaty except for a 
statement that they are politically, not legally, binding. 
Agreements under the Conference on Security and Cooperation in 
Europe (CSCE) are an example.
    Since non-binding agreements are not submitted to the 
Senate as treaties and are not transmitted to Congress as 
executive agreements under the Case-Zablocki Act, Congress may 
need to learn of the agreements and oversee them through other 
methods. In the case of the CSCE agreements, Congress has 
carried out vigorous oversight through the Commission on 
Security and Cooperation in Europe.

         D. Deciding Between Treaties and Executive Agreements

    The crux of the problem is determining when international 
agreements should be concluded as treaties and when they should 
be executive agreements. For what subjects is it essential to 
use the treaty process? For what subjects are executive 
agreements appropriate?

   scope of the treaty power; proper subject matter for treaties \30\
---------------------------------------------------------------------------

    \30\ See Chapters III and IV for references and additional 
discussion.
---------------------------------------------------------------------------
    The treaty power is recognized by the courts as extending 
to any matter properly the subject of international 
negotiations. In practice the subject matter dealt with by 
international negotiations has steadily expanded, particularly 
in the last half century, with new forms of international 
cooperation in political, military, economic, and social 
fields.
    From time to time concern has been expressed that treaties 
could have adverse implications for, or the effect of changing, 
domestic law. For example, the negotiation of human rights 
treaties under the auspices of the United Nations raised 
concern in the 1950s that some clauses, if ratified by the 
United States, might be in conflict with constitutional 
provisions safeguarding human rights, or that matters clearly 
in the domestic jurisdiction of the United States could be 
changed into matters of international concern. Other concerns 
were that some national powers might be transferred to an 
international organization, or that powers traditionally 
reserved to the states could be invaded by transferring them to 
the Federal Government or international bodies.
    Despite its breadth, the treaty power has certain 
limitations in addition to the procedural safeguard of the 
requirement for the Senate's advice and consent. Chief among 
these is that treaties, like laws, are subject to the 
requirements of the Constitution. Controversial constitutional 
issues involving treaties include:
    (1) Rights reserved to the states.--While it seems settled 
that the unspecified reserved powers of the 10th amendment are 
not a bar to exercise of the treaty power, specific powers 
conferred on states arguably might provide restrictions.
    (2) Subjects in which the Constitution gave participation 
to the House of Representatives.--Powers delegated to Congress 
are not a limitation on subject matter which can be embraced by 
a treaty, but for many treaties, domestic effectiveness may 
depend on implementing legislation.
    (3) Authorizations of U.S. participation in proceedings 
before certain types of international judicial tribunals.--The 
Constitution's vesting of the judicial power in one Supreme 
Court and such inferior courts as Congress might establish 
provides a safeguard against infringement by treaty on the 
domestic judicial power.
    (4) Matters of domestic jurisdiction, not of international 
concern.--While there is no clear test of what matters are of 
international concern, the existence of such limitations 
appears to be generally accepted.
    (5) Separation of powers and rights under the Bill of 
Rights.--As a general matter, an agreement cannot alter the 
constitutional distribution of powers or impair 
constitutionally protected rights.

  scope of executive agreements; proper subject matter for executive 
                            agreements \31\
---------------------------------------------------------------------------

    \31\ See Chapter IV for references and additional discussion.
---------------------------------------------------------------------------
    The extent to which executive agreements can be utilized 
instead of treaties is perhaps the fundamental question in 
studying the Senate role in treaties, and is by no means wholly 
resolved.
    Congressional-executive or statutory agreements, authorized 
or approved by legislation, would appear to have the broadest 
constitutional basis. They have been used for such important 
subjects as joining international organizations, and the Senate 
in legislation has endorsed their possible use for arms control 
agreements and the making of national commitments.
    Many legal scholars consider statutory agreements 
interchangeable with treaties as a method of making 
international agreements. Some might even argue that because 
they require approval of both Houses of Congress, statutory 
agreements might be more appropriate for those questions which 
affect domestic law than treaties, which are considered only by 
the Senate. When implementing legislation is required, they are 
an efficient device because the approval of the agreement and 
the necessary legislation may be accomplished in a single step.
    Others might argue that to use congressional-executive 
agreements instead of treaties, while preserving the 
congressional role, could lead to erosion of the treaty power. 
Not only would it circumvent the method set out in the 
Constitution that deliberately made entering treaties more 
difficult than passing legislation, but it would indirectly 
reduce the influence of states whose interests were seen to be 
protected by requiring a two-thirds majority of the Senators 
voting. Some may object to the use of statutory agreements 
instead of treaties, when initiated by the executive branch, on 
the grounds that it allows the executive branch to pick and 
choose between the two methods of making international 
agreements according to the better prospects for approval; they 
may not object if Congress specifically authorizes such an 
agreement.
    The other two types of international agreements have 
narrower limits but pose other problems. Executive agreements 
pursuant to treaties are supposed to be within the purview of 
the treaty, that is, carry out the purposes of the treaty. Sole 
executive agreements are supposed to be within the President's 
independent executive powers under Article II of the 
Constitution. However, the extent of the ``purview of the 
treaty'' and the President's independent powers raise 
judgmental matters subject to varying interpretations.

                     criteria for treaty form \32\
---------------------------------------------------------------------------

    \32\ See Chapter X.
---------------------------------------------------------------------------
    A perennial concern of Senators has been to insure that the 
most important international commitments are made as treaties 
rather than executive agreements. There have been recurrent 
complaints that some agreements of major significance, such as 
agreements to establish military bases, were not submitted to 
the Senate as treaties.
    Procedures for consultation between the executive branch 
and Congress on the form of prospective international 
agreements, primarily whether they should be treaties submitted 
to the Senate, were developed in 1978 after the Senate passed 
the International Agreements Consultation Resolution suggesting 
that such consultation should occur. These procedures include 
State Department consultation with appropriate congressional 
committees in advance of negotiations. In addition, the 
Department is periodically to send the Senate Foreign Relations 
and House International Relations Committees a list of 
significant international agreements that it has authorized for 
negotiation. Congress can use the information provided as the 
basis for discussions with the Department of State, or possibly 
take more action, on the form an agreement should ultimately 
take.
    The State Department has developed the following criteria 
for determining whether an agreement should be a treaty:
    (1) The degree of commitment or risk for the entire Nation;
    (2) Whether the agreement is intended to affect state laws;
    (3) Whether the agreement requires enabling legislation;
    (4) Past U.S. practice;
    (5) The preference of Congress;
    (6) The degree of formality desired;
    (7) The proposed duration and the need for prompt 
conclusion; and
    (8) General international practice on similar agreements.
    When there is a question as to whether an agreement should 
be concluded as a treaty or executive agreement, State 
Department procedures call for consultation with congressional 
leaders and committees as may be appropriate. Fuller use of 
these and other consultation procedures appear to offer the 
most opportunity for assuring appropriate decisions, from the 
Senate's perspective, on whether particular international 
agreements should be concluded as executive agreements, 
congressional-executive agreements, or treaties.


  II. HISTORICAL BACKGROUND AND GROWTH OF INTERNATIONAL AGREEMENTS \1\

Powers.

                              ----------                              

    The Framers of the Constitution expected the Senate to 
serve as a council of advice to the President on treaty 
matters, participating during the negotiation stage through the 
end of the treatymaking process. The experience of President 
George Washington in 1789, in meeting with Senators to discuss 
the terms of a treaty to be negotiated with the Southern 
Indians, proved discouraging to both branches. Although no 
President again met with Senators in the Senate Chamber to 
discuss a proposed treaty, other methods were used to include 
Senators in the treaty-drafting process. The Senate's role 
evolved into a more formal pattern of passing judgment on 
completed treaties, approving or not approving them, or 
approving them with conditions that the President must accept 
if he ratifies them.
    Senate action on treaties has changed dramatically, 
particularly since World War II. While the number of treaties 
concluded each year has remained fairly constant, the number of 
international agreements other than treaties has skyrocketed. 
Moreover, a growing proportion of treaties are now multilateral 
rather than bilateral, and the subject matter of treaties and 
other international agreements continues to diversify. All of 
these changes challenged the Senate in maintaining its 
constitutional role.

         A. Historical Background of Constitutional Provisions

    Four provisions of the Constitution expressly relate to 
treaties and form the basis of U.S. law on treaties. By making 
treaties the supreme law of the land and dividing the 
treatymaking power between the President and the Senate, the 
Constitution makes treaties uniquely important and difficult 
for the United States.
    Article I, Section 10, expressly prohibits states from 
entering into ``any Treaty, Alliance, or Confederation,'' nor 
may any state, without the consent of Congress, enter into any 
agreement or compact or agreement with another state or with a 
foreign nation.
    Article II, Section 2, Clause 2, states that the President 
``shall have Power, by and with the Advice and Consent of the 
Senate, to make Treaties, provided two-thirds of the Senators 
present concur.''
    Article III, Section 2, Clause 1, provides: ``The judicial 
Power shall extend to all Cases, in Law and Equity, arising 
under this Constitution, the Laws of the United States, and 
Treaties made, or which shall be made, under their Authority; * 
* *''
    Article VI, Section 2, includes treaties among the supreme 
law of the land: ``This Constitution, and the Laws of the 
United States which shall be made in Pursuance thereof; and all 
Treaties made, or which shall be made, under the Authority of 
the United States, shall be the supreme Law of the Land; and 
the Judges in every State shall be bound thereby, any Thing in 
the Constitution or Laws of any State to the Contrary 
notwithstanding.''
    The background and records of the Constitutional Convention 
of 1787 and early writings and practice help reveal the 
intentions, concerns, and assumptions of the Drafters of the 
Constitution.

                     the constitutional convention

    The Articles of Confederation, completed in 1777 but not 
ratified until 1781, formed the basis of the relationship among 
the 13 colonies until superseded by the Constitution in 1789. 
The Continental Congress was the only central organ of the 
Confederation. The Articles vested in ``the united states in 
congress assembled'' the power to enter into treaties and 
alliances, ``provided that no treaty of commerce shall be made 
whereby the legislative power of the respective states shall be 
restrained from imposing such imposts and duties on foreigners, 
as their own people are subjected to, or from prohibiting the 
exportation or importation of any species of goods or 
commodities whatsoever * * *.'' Congress, a single body 
composed of delegates from each state, required the assent of 
nine states for a treaty.The main problem concerning treaties 
under the Articles was in securing agreement to make treaty 
provisions binding on all the states.
    At the Philadelphia Convention in 1787, a number of 
proposals were put forth to replace the Articles of 
Confederation. It was generally agreed that the single branch 
of the Continental Congress would be replaced by three 
branches: legislative, executive, and judicial. Well into 
August, the delegates agreed to give the Senate the exclusive 
power to make treaties and appoint ambassadors.\2\ Opposition 
developed, however. On August 15, John Mercer of Maryland 
objected to lodging the treatymaking power in the Senate, 
contending that it belonged to the executive department, adding 
that treaties ``would not be final so as to alter the laws of 
the land, till ratified by legislative authority.'' \3\ On 
August 23, James Madison pointed out that the Senate 
represented the states alone and that for ``this as well as 
other obvious reasons it was proper that the President should 
be an agent in Treaties.'' \4\

    By September 4 delegates had agreed that the President ``by 
and with the advice and consent of the Senate, shall have power 
to make treaties,'' and that no treaty shall be made without 
the consent of two-thirds of the Senators present.\5\ This 
portion of the report was brought up for discussion on 
September 7. James Wilson of Pennsylvania moved to add the 
words ``and House of Representatives'' after the word Senate 
because, he said, since treaties ``are to have the operation of 
laws, they ought to have the sanction of laws also.'' As to the 
objection that secrecy was needed for treatymaking, he said 
that factor was outweighed by the necessity for the sanction of 
both chambers. Roger Sherman of Connecticut argued that the 
requirement of secrecy for treaties ``forbade a reference of 
them to the whole Legislature.'' Wilson's motion was 
defeated.\6\

---------------------------------------------------------------------------
    Considerable attention was given to the size of the Senate 
majority that should be required. Wilson objected to requiring 
a two-thirds majority on the grounds that it ``puts it in the 
power of a minority to control the will of a majority.'' He was 
supported by Rufus King of Massachusetts, who pointed out that 
there was already a check by joining the President in the 
treatymaking process.\7\ Several amendments were defeated: (1) 
to allow two-thirds of the Senate to make treaties of peace 
without the President's concurrence; (2) to strike out 
altogether the clause requiring approval by two-thirds of the 
Senate; (3) to require the consent of two-thirds of all the 
members of the Senate; (4) to require a majority of the whole 
number of the Senate; (5) to establish that a quorum of the 
Senate consist of two-thirds of all the members; and (6) to 
provide that ``no Treaty shd. be made with[ou]t previous notice 
to the members, & a reasonable time for their attending.'' \8\

---------------------------------------------------------------------------
    A committee was then appointed to revise the style and 
arrangement of the articles that had been adopted, and the text 
reported back was finally approved by the convention as Section 
2 of Article II in its current form. Thus, the power to make 
treaties, at first given to the Senate by the Committee of 
Detail, was transferred to the President by and with the advice 
and consent of the Senate.

                           debate on adoption

    Further indications of the intended meaning of the 
constitutional provisions are found in ``The Federalist,'' a 
group of papers written by Alexander Hamilton, John Jay, and 
James Madison to explain and win support for the Constitution, 
and in debates in the State Constitutional Conventions called 
to decide on its adoption. These sources sustain the conclusion 
that the original intention was that the Senate and the 
President share the treatymaking power, with the sharing to 
begin early and continue throughout the treatymaking process.
    Federalist No. 75 by Hamilton ascribes a ``peculiar 
propriety'' to the union of the President and the Senate in the 
treatymaking process:
          Though several writers on the subject of government 
        place that power in the class of executive authorities, 
        yet this is evidently an arbitrary disposition; for if 
        we attend carefully to its operation, it will be found 
        to partake more of the legislative than of the 
        executive character, though it does not seem strictly 
        to fall within the definition of either of them. The 
        essence of the legislative authority is to enact laws, 
        or, in other words, to prescribe rules for the 
        regulation of the society; while the execution of the 
        laws, and the employment of the common strength, either 
        for this purpose or for the common defense, seem to 
        comprise all the functions of the executive magistrate. 
        The power of making treaties is, plainly neither the 
        one nor the other. * * * Its objects are CONTRACTS with 
        foreign nations, which have the force of law, but 
        derive it from the obligations of good faith. They are 
        not rules prescribed by the sovereign to the subject, 
        but agreements between sovereign and sovereign. The 
        power in question seems therefore to form a distinct 
        department, and to belong, properly, neither to the 
        legislative nor to the executive. The qualities 
        elsewhere detailed as indispensable in the management 
        of foreign negotiations, point out the Executive as the 
        most fit agent in those transactions; while the vast 
        importance of the trust, and the operation of treaties 
        as laws, plead strongly for the participation of the 
        whole or a portion of the legislative body in the 
        office of making them.\9\

Mass., Harvard University Press (1961), pp. 476-477.

    Federalist No. 64 by Jay foresees that on some occasions 
the President would undertake preparatory work on treaties 
alone but nevertheless would call upon the Senate in important 
matters:
          It seldom happens in the negotiation of treaties, of 
        whatever nature, but that perfect secrecy and immediate 
        despatch are sometimes requisite. There are cases where 
        the most useful intelligence may be obtained, if the 
        persons possessing it can be relieved from 
        apprehensions of discovery. Those apprehensions will 
        operate on those persons whether they are actuated by 
        mercenary or friendly motives; and there doubtless are 
        many of both descriptions, who would rely on the 
        secrecy of the President, but who would not confide in 
        that of the Senate, and still less in that of a large 
        popular Assembly. The convention have done well, 
        therefore, in so disposing of the power of making 
        treaties, that although the President must, in forming 
        them, act by the advice and consent of the Senate, yet 
        he will be able to manage the business of intelligence 
        in such a manner as prudence may suggest.
          * * * Those matters which in negotiations usually 
        require the most secrecy and the most despatch, are 
        those preparatory and auxiliary measures which are not 
        otherwise important in a national view, than as they 
        tend to facilitate the attainment of the objects of the 
        negotiation. For these, the President will find no 
        difficulty to provide; and should any circumstance 
        occur which requires the advice and consent of the 
        Senate, he may at any time convene them. * * *
          Some are displeased with it, not on account of any 
        errors or defects in it, but because, as the treaties, 
        when made, are to have the force of laws, they should 
        be made only by men vested with legislative authority. 
        * * *
          Others, though content that treaties should be made 
        in the mode proposed, are averse to their being the 
        supreme law of the land. They insist, and profess to 
        believe, that treaties like acts of assembly, should be 
        repealable at pleasure. This idea seems to be new and 
        peculiar to this country, but new errors, as well as 
        new truths, often appear. These gentlemen would do well 
        to reflect that a treaty is only another name for a 
        bargain, and that it would be impossible to find a 
        Nation who would make any bargain with us, which should 
        be binding on them absolutely, but on us only so long 
        and so far as we may think proper to be bound by 
        it.\10\
---------------------------------------------------------------------------
    \10\ Ibid., pp. 422-424.

    Pierce Butler, one of the delegates of the Federal 
Convention and a member of the committee that drafted the 
treaty clause, explained to the members of the South Carolina 
ratifying convention the reasons that lay behind the 
constitutional language:
          It was at first proposed to vest the sole power of 
        making peace or war in the Senate; but this was 
        objected to as inimical to the genius of a republic, by 
        destroying the necessary balance they were anxious to 
        preserve. Some gentlemen were inclined to give this 
        power to the President, but it was objected to, as 
        throwing into his hands the influence of a monarch, 
        having an opportunity of involving his country in a war 
        whenever he wished to promote her destruction. The 
        House of Representatives was then named; but an 
        insurmountable objection was made to this proposition--
        which was, that negotiations always required the 
        greatest secrecy, which could not be expected in a 
        large body.\11\
---------------------------------------------------------------------------
    \11\ The Debates in the Several State Conventions on the Adoption 
of the Federal Convention (Jonathan Elliot ed.), v. 4, p. 263.

    Charles Cotesworth Pinckney, who had originally proposed in 
the convention that the treatymaking power be given to the 
Senate alone, explained to the South Carolina Legislature that 
the Senate would approve or disapprove the terms of treaties 
proposed by the President.
          At last it was agreed to give the President a power 
        of proposing treaties, as he was the ostensible head of 
        the Union, and to vest the Senate (where each state had 
        an equal voice) with the power of agreeing or 
        disagreeing to the terms proposed. * * * On the whole, 
        a large majority of the Convention thought this power 
        would be more safely lodged where they had finally 
        vested it, than any where else. It was a power that 
        must necessarily be lodged somewhere: political caution 
        and republican jealousy rendered it improper for us to 
        vest in the President alone; the nature of negotiation, 
        and the frequent recess of the House of 
        Representatives, rendered that body an improper 
        depository of this prerogative. The President and 
        Senate joined were, therefore, after much deliberation, 
        deemed the most eligible corps in whom we could with 
        safety vest the diplomatic authority of the Union.\12\

                   B. Evolution into Current Practice

    Early practice in treatymaking lends further insight into 
the intentions of the Framers of the Constitution, as well as 
into factors bringing about current practice. The first 
President of the United States had also presided at the 
Constitutional Convention, and most of the Members of the 
Senate during his administrations either had been members of 
the Continental or Confederation Congresses or attended the 
Constitutional Convention or the state conventions called to 
adopt the Constitution.\13\
---------------------------------------------------------------------------
    \13\ ``Of the sixty-six men who served in the Senate during 
Washington's administrations, thirty-one had been members of the 
Constitutional Congress or of the Congress of the Confederation, twelve 
had helped draft the Constitution in the convention at Philadelphia, 
and ten had been members of state conventions which had ratified the 
Federal instrument.'' Hayden, Ralston. The Senate and Treaties, 1789-
1817. New York, Macmillan, 1920, p. 3.
---------------------------------------------------------------------------

                      washington's administrations

    On August 6, 1789, the Senate appointed a committee to 
confer with the President on the manner in which communications 
between them concerning treaties and nominations should be 
handled. In a message to the committee on August 8, 1789, 
President Washington stated that in all matters respecting 
treaties ``oral communications seem indispensably necessary; 
because in these a variety of matters are contained, all of 
which not only require consideration, but some of them may 
undergo much discussion; to do which by written communications 
would be tedious without being satisfactory.'' \14\ In a second 
message on August 10, he distinguished between appointments--in 
which ``the agency of the Senate is purely executive''--and 
treaties, where ``the agency is perhaps as much of a 
legislative nature and the business may possibly be referred to 
their deliberations in their legislative chamber.'' In this 
same message, he explained that the Senate was to be consulted 
in advance of making a treaty. Treaties would be presented to 
the Senate in an interim form (``propositions''), not as a 
completed product:

v. 30, p. 373.
---------------------------------------------------------------------------
          On some occasions it may be most convenient that the 
        President should attend the deliberations and decisions 
        on his propositions; on others that he should not; or 
        that he should not attend the whole of the time. In 
        other cases, again, as in Treaties of a complicated 
        nature, it may happen, that he will send his 
        propositions in writing and consult the Senate in 
        person after time shall have been allowed for 
        consideration.\15\
---------------------------------------------------------------------------
    \15\ Ibid., p. 378.

    President Washington recommended that the Senate should 
accommodate its rules to the uncertainty of the particular mode 
and place, provide for either oral or written propositions, and 
for giving consent and advice in either the presence or absence 
of the President, leaving the President free to establish the 
mode and place.
    Accordingly, on August 21, 1789, the Senate adopted a rule 
on the procedure to be followed when the President met with the 
Senate. The rule covered both appointments and treaties:
          Resolved, That when nominations shall be made in 
        writing by the President of the United States to the 
        Senate, a future day shall be assigned, unless the 
        Senate unanimously direct otherwise, for taking them 
        into consideration; that when the President of the 
        United States shall meet the Senate in the Senate 
        Chamber, the President of the Senate shall have a chair 
        on the floor, be considered as at the head of the 
        Senate, and his chair shall be assigned to the 
        President of the United States; that when the Senate 
        shall be convened by the President of the United States 
        to any other place, the President of the Senate and 
        Senators shall attend at the place appointed. The 
        Secretary of the Senate shall also attend to take the 
        minutes of the Senate.
          That all questions shall be put by the President of 
        the Senate, either in the presence or absence of the 
        President of the United States; and the Senators shall 
        signify their assent or dissent by answering viva voce, 
        aye or no.\16\

    The same day President Washington gave notice of his 
intention to meet with the Senate to consider the terms of a 
treaty to be negotiated with the Southern Indians. The next 
day, Saturday, President Washington came into the Senate 
Chamber, accompanied by Secretary of War Henry Knox, and 
presented a paper giving an explanation of the proposed treaty. 
He then asked the Senate for its advice and consent on seven 
questions to guide the commissioners who were negotiating the 
treaty. At his request, the Senate postponed voting on the 
first question. On the second question, regarding instructions 
to the commissioners to pursue other measures respecting the 
Chickasaws and Choctaws, the Senate voted in the negative.\17\ 
On Monday, August 24, the President again returned to the 
Senate Chamber and votes were taken on the rest of the 
questions.\18\

    These meetings between the Senate and the President are 
famous as the first and last times that a President personally 
appeared before the Senate to seek its advice and consent. The 
meetings apparently were not satisfactory to either side. While 
the Executive Journal of the Senate does not record the debate, 
William Maclay, a Senator from Pennsylvania, recorded in his 
journal the difficulty of hearing the discussion and the 
seeming haste for decisions. Because of the noise created by 
carriages driving past, Maclay ``could tell it was something 
about Indians, but was not master of one sentence of it.'' When 
it was proposed that the questions be referred to a committee, 
Washington ``started up in a violent fret'' and stated that 
``This defeats every purpose of my coming here.'' Maclay also 
wrote:
          I had, at an early stage of the business, whispered 
        to Mr. Morris that, I thought, the best way to conduct 
        the business was to have all the papers committed. My 
        reasons were that I saw no chance of a fair 
        investigation of subjects while the President of the 
        United States sat there, with his Secretary of War to 
        support his opinions, and overawe the timid and neutral 
        part of the Senate.\19\

    The dissatisfaction on the President's side is often 
illustrated with the following quotation from the memoirs of 
John Quincy Adams:
          Mr. Crawford told twice over the story of President 
        Washington's having at an early period of his 
        Administration gone to the Senate with a project of a 
        treaty to be negotiated, and been present at their 
        deliberations upon it. They debated it and proposed 
        alterations, so that when Washington left the Senate-
        chamber he said he would be damned if he ever went 
        there again. And ever since that time treaties have 
        been negotiated by the Executive before submitting them 
        to the consideration of the Senate.\20\

    It is error to conclude from this unhappy incident that 
Washington and future Presidents thereafter excluded the Senate 
from the treaty negotiation process. Washington continued to 
seek the advice of Senators, but he did so through written 
communications rather than personal appearances. For example, 
on February 9, 1790, he wrote to the Senate about a boundary 
line between U.S. and British territories. He thought ``it 
advisable to postpone any negotiations on the subject until I 
shall be informed of the result of your deliberations and 
receive your advice as to the propositions most proper to be 
offered on the part of the United States.'' \21\ On May 8, 
1792, he asked the Senate these questions:

          If the President of the United States should conclude 
        a convention or treaty with the Government of Algiers 
        for the ransom of the thirteen Americans in captivity 
        there for a sum not exceeding $40,000, all expenses 
        included, will the Senate approve the same? Or is there 
        any, and what, greater or lesser sum which they would 
        fix on as the limit beyond which they would not approve 
        the ransom?

        a treaty with the Government of Algiers for the 
        establishment of peace with them, at an expense not 
        exceeding $25,000, paid at the signature, and a like 
        sum to be paid annually afterwards during the 
        continuance of the treaty, would the Senate approve the 
        same? Or are there any greater or lesser sums which 
        they would fix on as the limits beyond which they would 
        not approve of such treaty? \22\

    On some occasions, however, President Washington did not 
consult the Senate in advance of negotiations. Four treaties 
with Indian tribes negotiated during Washington's 
administrations without prior consultation with the Senate were 
approved. In regard to one of these, the Treaty of Greenville 
with the Indians northwest of the Ohio, Washington consulted 
his Cabinet on whether consultations with the Senate should be 
undertaken prior to negotiation and the Cabinet unanimously 
expressed the opinion it would be better not to. Thomas 
Jefferson wrote that all thought that if the Senate were 
consulted and told of plans, it would become known to the 
British minister and ``we would lose all chance of saving 
anything more than our ultimatum.'' \23\

     In the case of the Jay Treaty with Great Britain of 
November 19, 1794, a few Senators helped initiate the treaty 
and were prominent in its negotiation, but the President did 
not obtain the advice and consent of the entire Senate on the 
instructions to the negotiation. Just before approving the 
appointment of John Jay as special envoy to Britain, the Senate 
rejected a motion asking the President to supply it with 
complete information on the business to be charged to Jay. 
However, it was recognized that the treaty would have to be 
negotiated subject to obtaining the consent of the Senate to 
ratification. When the final treaty was put before the Senate, 
the Senate made its consent conditional upon alteration of the 
treaty. After the revisions requested by the Senate were made 
and accepted by Britain, the President ratified the revised 
treaty without further submission to the Senate.
    The Senate on one occasion was called upon to assist in the 
interpretation of a treaty. In 1791, France contended that 
certain acts of Congress imposing requirements on ships without 
excepting those of France were in contravention of the Treaty 
of 1778. After considering various alternatives presented by 
the Secretary of State, the Senate expressed the opinion that 
the American interpretation of the treaty was correct and 
advised that this answer be given to France in the most 
friendly manner. This course was adopted.\24\
---------------------------------------------------------------------------
    \24\ Hayden, op. cit., p. 101.
---------------------------------------------------------------------------
    The conclusions of one student of the subject on the 
evolution of the treatymaking procedures during Washington's 
administrations have been stated as follows:
          One very important decision reached by the logic of 
        events during these eight years, however, was that the 
        Senate could not really be a ``council of advice'' to 
        the President in treaty-making. Yet evidently both 
        Washington and the Senate originally expected that it 
        would be such a council. The personal element in their 
        relations was emphasized by the presence of the 
        Secretary of State or the Secretary of War, or, in the 
        one instance, of the President himself, at their 
        deliberations.
          As the Senate ceased to be consulted as a real 
        ``council of advice,'' its activities in that part of 
        treaty-making known as the negotiation became less 
        important. At first in making treaties both with the 
        Indian tribes and with foreign nations the President 
        usually secured the advice and consent of the Senate to 
        the details of the proposed treaty before opening the 
        negotiation. In the end it became his custom merely to 
        inform the Senate of the proposed negotiation upon 
        securing its consent to the nomination of the agent, 
        and to submit the latter's instructions only with the 
        completed treaty. * * * The effect of the change in 
        procedure was to leave the President free to negotiate 
        the sort of treaty which the necessities of the 
        situation demanded and allowed, while the Senate 
        retained a like freedom to accept, to amend, or to 
        reject the result of his efforts.\25\

                    presidencies from adams to polk

    During subsequent administrations, the respective roles of 
the Senate and the President were further refined. Through its 
action on the Treaty of 1797 with Tunis, the Senate established 
its right to make its approval of a treaty conditional upon 
changes in the text or terms that might require renegotiation. 
In the European monarchies prior to that time, it had been 
considered obligatory for the monarchies to ratify a treaty if 
his emissary had stayed within his instructions, and no 
practice existed of reservations to parts of treaties. After 
considering the treaty with Tunis, the Senate adopted a 
resolution advising and consenting to its ratification on 
condition that a certain article be suspended and recommending 
renegotiation of the article. Renegotiation was undertaken and 
the Senate subsequently gave its advice and consent to the 
ratification of the article in question and two other articles 
that were renegotiated.\26\ The King-Hawksbury Convention of 
May 12, 1803, became the first treaty not to enter into force 
because the other party, Great Britain, would not accept an 
amendment advised by the Senate. Lord Harrowby, the head of the 
British Foreign Office at that time, criticized the practice of 
ratifying treaties with exceptions to parts of them, a practice 
which he called ``new, unauthorized and not to be sanctioned.'' 
\27\ Gradually, however, other countries became used to the 
American procedure.

    President Andrew Jackson appreciated the value of seeking 
the advice of Senators on how best to pursue treaty 
negotiations. On May 6, 1830, he submitted to the Senate 
``propositions'' for a treaty with the Chocktaw Indians. He 
indicated the amendments he thought necessary, but elicited the 
Senate's views: ``Not being tenacious though, on the subject, I 
will most cheerfully adopt any modifications which, on a frank 
interchange of opinions my Constitutional advisors may suggest 
and which I shall be satisfied are reconcilable with my 
official duties.'' \28\ He explained that the Indians 
recommended that their propositions be submitted to the Senate, 
and that the Senate's opinion ``will have a salutary effect in 
a future negotiation, if one should be deemed proper.'' \29\ 
Instead of acting unilaterally, Jackson thought it would be 
more satisfactory to the American people and to the Indians to 
have ``the united counsel of the treatymaking power.'' \30\

    President James K. Polk also invited the Senate's advice on 
negotiating a treaty. He regarded the Senate as ``a branch of 
the treatymaking power, and by consulting them in advance of 
his own action upon important measures of foreign policy which 
may ultimately come before them for their consideration the 
President secures harmony of action between that body and 
himself.'' \31\

                            indian treaties

    Conclusion of treaties with Indian tribes ended in 1871. 
For almost a century, Indian tribes were treated as independent 
nations and subjected to the treatymaking power of the 
President and the Senate. However, the Constitution also 
empowers Congress to ``regulate Commerce with foreign Nations, 
and among the several States, and with the Indian Tribes.'' 
Partly because of corruption and mismanagement in the Office of 
Indian Affairs, the House of Representatives began to object to 
its exclusion from Indian affairs. In 1869, the Senate added 
funds to an appropriations bill to fulfill Indian treaties it 
had approved, but the House refused to grant the funds.\32\ In 
1871, the House completed its reassertion by enacting this 
language: ``Provided, That hereafter no Indian Nation or tribe 
within the territory of the United States shall be acknowledged 
or recognized as an independent nation, tribe, or power with 
whom the United States may contract by treaty.'' \33\ That 
language was later incorporated into permanent law as 25 U.S.C. 
Sec. 71 (1994).

                       conflicts and cooperation

    Presidents have varied in their attitude toward Senate 
participation in the treaty process. Some have included 
Senators; others have kept the negotiation of treaties an 
executive monopoly. President Woodrow Wilson believed that the 
President should not consult with the Senate and treat it as an 
equal partner. He applied this theory to the Versailles Treaty, 
which the Senate twice rejected.\34\ On the other hand, 
Presidents such as William McKinley, Warren Harding, and 
Herbert Hoover included Senators and Representatives as members 
of U.S. delegations that negotiated treaties. The details of 
the U.N. Charter were hammered out at a conference in San 
Francisco in 1945. Half of the eight members of the U.S. 
delegation came from Congress: Senators Tom Connally (D-Tex.) 
and Arthur H. Vandenberg (R-Mich.) and Representatives Sol 
Bloom (D-N.Y.) and Charles A. Eaton (R-N.J.).

    The notion that the President is the exclusive negotiator 
of treaties and international agreements has been undercut by 
recent trade legislation, which gives Congress a direct role in 
the negotiation process. It has become the practice of Congress 
to offer the President a ``fast-track'' legislative procedure 
for implementing trade agreements with other nations. Fast-
track means that the President's implementing bill is 
automatically introduced in Congress, committees must act 
within a specified number of days, Congress must complete floor 
action within a limited time, and amendments to the bill are 
prohibited either in committee or on the floor. Through this 
procedure, leaders of foreign governments (often with 
parliamentary systems that vest strong powers in the Executive) 
are assured that the trade pact will be given expedited 
consideration by Congress.
    In obtaining these procedural benefits, the President 
recognizes that Members of Congress must be closely involved in 
the negotiations that produce the implementing bill. In 1991, 
after President George Bush asked Congress to extend the fast 
track for a trade pact with Mexico, U.S. Trade Representative 
Carla A. Hills told the Senate Finance Committee that the fast 
track ``is a genuine partnership between the two branches.'' 
Because Congress retained the power to defeat the implementing 
bill, Hills emphasized that Congress ``has a full role 
throughout the entire process in formulating the negotiating 
objectives in close consultation as the negotiations proceed.'' 
\38\ President Bush gave Congress his ``personal commitment to 
close bipartisan cooperation in the negotiations and beyond.''

            executive agreements and multilateral agreements

    Early practice ushered in the use of ``executive 
agreements'': international agreements that are not submitted 
to the Senate as treaties.\40\ Legislation in 1792 authorized 
the Postmaster General to make arrangements with foreign 
postmasters for the receipt and delivery of letters and 
packets.\41\ Executive officials also entered into reciprocal 
trade agreements on the basis of statutory authority. Although 
such agreements lacked what the Supreme Court in 1912 called 
the ``dignity'' of a treaty, since they do not require Senate 
approval, they are nonetheless valid international 
compacts.\42\

agreements, see Chapter IV.

United States v. Pink, 315 U.S. 203, 230 (1942), Justice Douglas 
regarded executive agreements as having a ``similar dignity'' with 
treaties.
---------------------------------------------------------------------------
    After the Second World War, the United States entered into 
a dramatically increasing number of international agreements, 
and most of these were concluded as executive agreements. Table 
II-1 depicts the tremendous growth in the number of U.S. 
treaties and other international agreements in 50-year periods 
from 1789 through 1989 and Table II-2 depicts the annual growth 
since 1930. These statistics on treaties and agreements 
``concluded'' means agreements that completed the negotiation 
stage and have been signed but may not yet have entered into 
force. In this data ``concluded'' does not mean agreements and 
treaties that have all entered into force.
    As apparent from the charts, after 1945 the number of 
international agreements concluded annually escalated rapidly. 
One factor was the continuing increase in the number of newly

ent nations with which the United States interacts. Treaties in 
the early days of the Nation were limited to Indian tribes and 
a comparatively few foreign powers, including France, Great 
Britain, Algiers, Spain, and Russia. By January 1, 1999, the 
United States had bilateral treaties or other international 
agreements with more than 200 countries.\43\

---------------------------------------------------------------------------
    Another factor was the growing international cooperation of 
the United States, and the continuing emergence of new fields 
of international cooperation, such as atomic energy, space 
research, and satellites. Agreements with a single country 
often cover a whole range of subjects ranging from aviation, 
commerce, and defense to environmental cooperation, patents, 
and taxation. The United States had more than 200 international 
agreements with the United Kingdom in force in 1999, for 
example, listed under almost 60 different subjects.\44\

    Cumulatively, in 1989 the United States was a party to 890 
treaties and 5,117 executive agreements.\45\ The total number 
of treaties and other international agreements in force 
increases with time because, once entered into, agreements 
remain in force until they expire by their own terms or are 
denounced, replaced, or superceded. While some international 
agreements are by their terms temporary or limited to a 
specific time period, others are intended to be more or less 
permanent. To illustrate, still listed among treaties in force 
with the United Kingdom are the Paris Peace Treaty of 1783, the 
Jay Treaty of 1794, and the Treaty of Peace and Amity signed at 
Ghent in 1814.

---------------------------------------------------------------------------

      increasing proportion of executive and statutory agreements

    Accompanying the increase in international agreements was 
the increase of international agreements other than treaties, 
that is, agreements not submitted to the Senate. As the 
preceding table shows, in the first 50 years of U.S. history, 
twice as many treaties were concluded as executive agreements. 
In the 50-year period from 1839 to 1889 a few more executive 
agreements than treaties were concluded. In the 50-year period 
from 1889 to 1939 almost twice as many executive agreements as 
treaties were concluded. In the period since 1939 executive 
agreements have comprised more than 90 percent of the 
international agreements concluded.
    The growth in executive agreements may be accounted for by 
a number of factors.\46\ A primary factor is the sheer increase 
in volume of the amount of business and contacts between the 
United States and other countries. Many observers believe it 
would be impractical to submit every international agreement 
the United States enters to the Senate as a treaty. An 
executive agreement is usually much simpler to conclude or 
amend than a treaty. The Senate, with an already heavy 
workload, would quickly find itself overburdened if all 
international agreements, no matter how minor in importance, 
were submitted to it for advice and consent.
---------------------------------------------------------------------------
    \46\ Some of the increase since 1973 may be attributed to the 
counting of agency level agreements that may not have been counted 
prior to the passage of the Case-Zablocki Act in 1973, just as the 
decrease in 1991 may be accounted for partly by the cessation of the 
reporting under the Case-Zablocki Act of agricultural commodity 
agreements. See Chapter X.
---------------------------------------------------------------------------
    Most executive agreements are concluded under the authority 
of a statute or prior treaty.\47\ In a wide variety of laws 
Congress has authorized the executive branch to conclude 
international agreements in fields including foreign aid, 
agriculture, and mutual security. Similarly, the Senate has 
approved numerous treaties that implicitly or explicitly 
authorized further agreement among the parties. As an example, 
the executive branch has concluded numerous defense and base 
agreements on the basis of the North Atlantic Treaty and other 
security treaties. One study found that 88.3 percent of 
international agreements reached between 1946 and 1972 were 
based at least partly on statutory authority; 6.2 percent on 
treaties, and 5.5 percent solely on executive authority.\48\

Practices. Prepared by the Congressional Research Service, Library of

See further discussion in Chapters IV and X.
---------------------------------------------------------------------------
    An increasing number of international agreements require 
the specific approval of Congress before entry into force 
rather than being submitted as treaties to the Senate. On 
occasion, this has been done at the initiative of the executive 
branch with the knowledge that an international agreement was 
unlikely to receive the approval of two-thirds of the Senate, 
or to assure that funds for implementation would be approved by 
the House of Representatives. One historian knowledgeable about 
executive agreements wrote, ``On certain occasions, when the 
treatymaking method has failed or seemed likely to fail, he 
[the President] has accomplished his purpose by substituting 
the more facile type of instrument.'' \49\
---------------------------------------------------------------------------
    \49\ McClure, Wallace Mitchell. International Executive Agreements. 
New York, Columbia University Press, 1941, p. 4.
---------------------------------------------------------------------------
    More often, legislation has required that executive 
agreements in some categories be submitted to Congress for 
specific approval or for tacit approval (through no negative 
action in a specified time period) before they enter into 
force. In trade legislation, Congress has authorized the 
President to negotiate certain agreements but has required that 
Congress approve the agreements, as well as requiring the 
executive branch to notify and consult with Congress during the 
negotiations. Nuclear, fisheries, and social security 
agreements are among those required by law to lie before 
Congress for specified time periods before they can enter into 
force. During this period, Congress can pass legislation 
disapproving the agreements, often with expedited procedures.
    The increasing use of international agreements other than 
treaties challenged the Senate to oversee that the executive 
agreement process was not used when agreements should properly 
be submitted to the Senate as treaties. Similarly, the 
increasing rise of agreements requiring approval by Congress, 
while assuring a congressional role, challenged the Senate to 
distinguish which types of agreements required submission to 
the Senate under the traditional treaty procedure.\50\
---------------------------------------------------------------------------
    \50\ See Chapter X.
---------------------------------------------------------------------------

                   growth in multilateral agreements

    The third main change in the field of international 
agreements is the growth of multilateral agreements, agreements 
among three or more parties as opposed to bilateral treaties 
between two parties. Multilateral agreements for the United 
States were rare prior to the 20th century. After the end of 
the Second World War, their numbers grew as nations found a 
multilateral treaty could render unnecessary dozens of 
bilateral treaties and establish an agreed international 
standard. From 1980 through 1999, the United States concluded 
or acceded to 450 multilateral agreements.\51\
---------------------------------------------------------------------------
    \51\ Information from Office of the Assistant Legal Adviser for 
Treaty Affairs, September 29, 2000.
---------------------------------------------------------------------------
    Multilateral agreements vary widely in number of parties, 
subject matter, and significance. Some have only three parties, 
but others have more than 150. As of October 2000, for example, 
the United Nations had 189 members.\52\ Multilateral agreements 
cover more than 200 different subject areas ranging from Africa 
to World War II and agriculture to women's political 
rights.\53\ Many multilateral agreements establish 
international organizations, which in turn conclude bilateral 
agreements with the United States. The United States has 
concluded bilateral agreements with approximately 50 
international organizations.\54\ Some of these concern routine 
matters such as reimbursement of taxes of employees of these 
organizations, but others concern subjects of broader 
significance, such as the application of international atomic 
energy safeguards in the United States.
---------------------------------------------------------------------------
    \52\ The 189th member was Tuvalu.
    \53\ See Treaties in Force, 1999, pp. v-vii, 331-478.
    \54\ Compiled from Treaties in Force, 1999, pp. iii-v.
---------------------------------------------------------------------------
    Although multilateral executive agreements being concluded 
outnumber multilateral treaties, multilateral agreements form a 
far larger proportion of treaties than of executive agreements. 
Of 415 treaties that the United States concluded from 1980 
through 1999, 155 (37 percent) were multilateral; of 6,381 
executive agreements, 294 (4.6 percent) were multilateral.\55\
---------------------------------------------------------------------------
    \55\ Information from Office of the Assistant Legal Adviser for 
Treaty Affairs, September 29, 2000.
---------------------------------------------------------------------------
    Like executive agreements, the growing number of 
multilateral agreements brought new challenges to the role of 
the Senate in the treatymaking process. A major challenge was 
the pressure to approve a multilateral treaty without 
reservation because of the large number of nations that had 
been involved and the difficulty of renegotiation. Some 
multilateral treaties have contained an article prohibiting 
conditions. The Senate Foreign Relations Committee has said 
that its approval of these treaties should not be construed as 
a precedent for such clauses in future treaties. In the 
committee's view, ``The President's agreement to such a 
prohibition can not constrain the Senate's constitutional right 
and obligation to give its advice and consent to a treaty 
subject to any reservation it might determine is required by 
the national interest.'' \56\

    Treaties are governed by international law and are a 
primary source of international law. They play a central role 
in the orderly conduct of relations among states. In order for 
treaties to perform this role, internationally recognized rules 
governing treaties have developed. Traditionally, treaty rules 
were established by custom and practice, and as a result they 
were not precisely defined.
    Under international law, the term ``treaty'' is applied to 
all binding international agreements between states or between 
states and international organizations. The term 
``international agreement,'' however, includes both binding and 
non-binding agreements. The term ``executive agreement'' is a 
creature of U.S. domestic law, not international law; 
``executive agreements'' that are binding international 
agreements are considered to be ``treaties'' in international 
law terminology.
    This chapter examines the definition of a treaty under 
international law and utilizes the 1969 Vienna Convention on 
the Law of Treaties and the Restatement (Third) of the Foreign 
Relations Law of the United States, as primary sources for such 
law. Because the United States has not ratified the convention, 
its international law status for non-parties is discussed. The 
chapter also reviews the criteria, under international law, 
which make an agreement binding; the principles which can 
render a binding agreement invalid; and the status of ``non-
binding'' agreements and statements under international law.

            A. The Vienna Convention on the Law of Treaties

                        international law status

    The Vienna Convention is in force internationally and has 
been ratified by or acceded to by 91 countries.\2\ The United 
States has signed but has not ratified the Vienna Convention 
and thus is not legally bound by its provisions.\3\ 
Nevertheless, the convention retains its status as a primary 
source of international law concerning treaties, even for non-
parties. The convention is partly a codification of customary 
international law, but also partly a development of 
international law and a reconciliation of different theories 
and practices; provisions in the latter category are binding 
only on the parties.\4\ Furthermore, the convention was not 
intended to be a complete codification of treaty law, and 
issues not covered by the convention continue to be covered by 
principles of customary international law.\5\ The Department of 
State describes the convention as a widely regarded ``major 
achievement in the development and codification of 
international law.'' \6\
---------------------------------------------------------------------------
    \2\ The Vienna Convention on the Law of Treaties, concluded at 
Vienna on May 23, 1969, entered into force for the countries that had 
ratified it on January 27, 1980, upon its ratification or accession by 
35 foreign countries. As of January 19, 2001, it had 46 signatories and 
91 parties. For the text of the Vienna Convention on the Law of 
Treaties and a list of parties thereto, see Appendix 5.

F. Salans, Acting Legal Adviser, Department of State, before the Senate 
Committee on Foreign Relations, August 3, 1972.
---------------------------------------------------------------------------
    In his letter transmitting the Vienna Convention to the 
President, Secretary of State William P. Rogers referred to it 
as ``* * * a generally agreed body of rules to govern all 
aspects of treaty making and treaty observance.'' He called the 
convention ``* * * an expertly designed formulation of 
contemporary treaty law * * * [that] * * * should contribute 
importantly to the stability of treaty relationships. * * * 
Although not in force, [for the United States] the Convention 
is already recognized as the authoritative guide to current 
treaty law and practice.'' (emphasis added.) \7\
---------------------------------------------------------------------------
    \7\ S. Exec. Doc. L, at 1.
---------------------------------------------------------------------------
    President Richard Nixon attributed similar status to the 
convention when, upon sending it to the Senate, he stated that:
        The growing importance of treaties in the orderly 
        conduct of international relations has made 
        increasingly evident the need for clear, well-defined, 
        and readily ascertainable rules of international law 
        applicable to treaties. I believe that the codification 
        of treaty law formulated by representatives of the 
        international community and embodied in the Vienna 
        Convention meets this need.\8\
---------------------------------------------------------------------------
    \8\ S. Exec. Doc. L, Letter of Transmittal. Despite the 
authoritative status of the convention under international law, in a 
few instances it appears to differ from customary international law and 
U.S. practice. For example, the convention definition of a treaty does 
not include oral agreements (Article 2) although according to the 
convention, its definition shall not affect the legal force of such 
agreements (Article 3(a)). Also, the convention permits a treaty to 
prohibit reservations (Article 19), which is contrary to the strong 
position taken by the Senate Foreign Relations Committee against the 
inclusion of provisions in agreements that would inhibit the power of 
the Senate to attach reservations. However, it has recommended advice 
and consent to some treaties containing such provisions, while 
affirming opposition to such provisions and declaring that approval of 
a treaty containing such a provision is not to be considered a 
precedent for acceptance of such provisions. See S. Exec. Rept. 105-25, 
at 18-19 (1998) (the World Intellectual Property Organization Copyright 
Treaty and Performances and Phonograms Treaty); S. Exec. Rept. 102-55, 
at 15 (1992) (the United Nations Framework Convention on Climate 
Changes); S. Exec. Rept. 102-54 (1992) (the Protocol on Environmental 
Protection to the Antarctic Treaty); S. Exec. Rept. 85-3, at 17 (1957) 
(Statute of International Atomic Energy Agency). Regarding differences 
between customary and conventional treaty law, see American Law 
Institute, Restatement (Third) of the Foreign Relations Law of the 
United States (1987) (hereafter cited as Rest. 3d). The Restatement 
accepts the Vienna Convention as, in general, constituting a 
codification of the customary international law governing international 
agreements, and therefore as foreign relations law of the United States 
even though the United States has not adhered to the convention. In a 
few instances, the convention moves beyond or deviates from accepted 
customary international law, and the Restatement therefore departs from 
the convention pending U.S. adherence to it. In a few other instances, 
the difference between the convention and customary law is a matter of 
emphasis and degree and can be accommodated within the text of the 
convention. Since the United States may become a party to the 
convention, the Restatement uses the text of the convention as a guide, 
with deviations indicated as appropriate in Comment and Reporters' 
notes. Rest. 3d, Vol. I, Part III, Introductory Note, at 145.

    The State Department's position on the status of the Vienna 
Convention largely accords with the positions of most members 
of the international community.\9\ This status stems in part 
from the concept that international treaties constitute one of 
the most significant sources of international law. For example, 
the Statute of the International Court of Justice directs the 
Court, when deciding disputes, to apply international law 
gleaned from a variety of sources beginning with international 
conventions.\10\
---------------------------------------------------------------------------
    \9\ The convention is the final product of a U.N. Conference on the 
Law of Treaties. The International Law Commission, which initially 
drafted the convention, was established to implement Article 13 of the 
U.N. Charter, which called for the General Assembly to initiate studies 
and make recommendations for purposes that include the ``progressive 
development of international law and its codification.'' Article 1 of 
the International Law Commission's statute charged it with this task. 
See G.A. Res. 174 (II), U.N. GAOR, 2d Sess., November 21, 1947. Members 
of the U.S. Senate were apparently not participants in, and not 
consulted on, the Commission's drafting or adoption of its final draft 
text of the Vienna Convention. However, as the Commission's membership 
consists of individual members and not government delegations, no 
requirement for either formal or informal Senate involvement existed at 
this stage of the convention's formulation.
    \10\ Article 38 of the Statute of the International Court of 
Justice, June 26, 1945. Other sources of international law cited by 
this Article include international custom and general principles of law 
recognized by civilized nations. Domestic judicial decisions and the 
teachings of judicial scholars are named as subsidiary means for the 
determination of rules of international law.
---------------------------------------------------------------------------
    Multilateral agreements, of which the Vienna Convention is 
a prime example, are not only an evidentiary source of 
recognized customary international law. They may also 
contribute to the progressive development of international law 
by expressing rules which may not yet be fully recognized by 
the international community. The International Court of Justice 
has on occasion noted that provisions contained in such 
agreements may be binding on a state as customary law even if a 
state is not a party to the agreement.\11\ A determination of 
whether a given provision of such an agreement expresses 
customary law may entail a consideration of (1) whether the 
provision was intended to codify settled law at the time of 
drafting, (2) whether an evolving rule of settled law expressed 
by the provision had become settled customary law by the time 
the agreement was concluded or entered into force, and finally, 
(3) whether a rule, which was experimental or evolving when the 
agreement expressing it in a provision was concluded or entered 
into force, has become customary international law with the 
passage of time since the agreement's conclusion or entry into 
force.\12\ So the Vienna Convention contains rules governing 
treaty relationships that are recognized as general principles 
of international law by the executive and judicial branches of 
the United States, as well as by the international community, 
even though the United States has not ratified it.\13\ Senate 
advice and consent to future treaties will, as a result, be 
influenced by the Vienna Convention, even if the United States 
does not become a party to it.

                    senate action on the convention

    The Vienna Convention on the Law of Treaties was sent to 
the Senate on November 22, 1971, and remains in committee. The 
Senate Committee on Foreign Relations ordered reported a 
Resolution of Advice and Consent to the Ratification of the 
Convention on September 7, 1972, subject to an understanding 
and interpretation. The Department of State opposed the wording 
of the understanding, and the convention was reconsidered in 
executive session by the committee, but not reported out.\14\
---------------------------------------------------------------------------
    \14\ See U.S. Department of State, Digest of United States Practice 
in International Law, 1974, 195-198 (1975) (hereafter cited as Digest, 
1974).
---------------------------------------------------------------------------
    The wording proposed by the committee read:
        subject to the interpretation and understanding, * * * 
        that, in accordance with Article 46 of the Convention 
        [relating to a state's right to invalidate a treaty if 
        its consent was obtained by a manifest violation of an 
        internal law of fundamental importance], since Article 
        2, Section 2, of the United States Constitution states 
        that the President ``shall have power, by and with the 
        advice and consent of the Senate, to make treaties, 
        provided two-thirds of the Senators present concur,'' 
        it is a rule of internal law of the United States of 
        fundamental importance that no treaty (as defined by 
        paragraph 1(a) of Article 2 of the Convention) is valid 
        with respect to the United States, and the consent of 
        the United States may not be given regarding any such 
        treaty, unless the Senate of the United States has 
        given its advice and consent to such treaty, or the 
        terms of such treaty have been approved by law, as the 
        case may be.\15\
---------------------------------------------------------------------------
    \15\ Ibid., at 195 (comments and emphasis added).

    Acceptance of this wording would have achieved two 
objectives desired by the Senate committee. First, it would 
have made clear that the Vienna Convention does not establish 
an international law rule which could hold the United States 
bound to a treaty which a President had signed, but which the 
Senate had not accepted.\16\ Furthermore, it would have made 
clear that an international instrument is voidable if concluded 
by a President in the form of an executive agreement that 
should have been treated either as a treaty under Article II, 
Section 2, to which the Senate should have consented, or 
presumably a congressional-executive agreement to which both 
Houses of Congress should have agreed. The wording of the 
proposed Senate interpretation would seem to make agreements 
concluded by a President, on his own independent constitutional 
authority, subject to Senate advice and consent. The wording, 
therefore, could be seen as severely limiting a President's 
independent authority to make binding and firm international 
commitments.
---------------------------------------------------------------------------
    \16\ The convention does not definitively resolve this issue. See 
later discussion in this chapter entitled: ``Invalidation by Violation 
of Domestic Law Governing Treaties.''
---------------------------------------------------------------------------
    The wording of the Senate's interpretation was not 
acceptable to the executive branch because the term ``treaty'' 
under the Vienna Convention includes agreements which are not 
``treaties'' under Article II, Section 2, of the 
Constitution.\17\ In response to the Senate's proposed 
interpretation and understanding, the Department of State 
suggested that the Senate's intent could be expressed along the 
following lines: ``with the understanding and interpretation 
that ratification of the Convention by the United States does 
not give any international agreement of the United States any 
internal standing under the Constitution of the United States 
that it would not have in the absence of the Convention.'' \18\
---------------------------------------------------------------------------
    \17\ This is the part of the U.S. Constitution which requires 
Senate advice and consent to treaties.
    \18\ See Digest, 1974, supra note 14, at 197.
---------------------------------------------------------------------------
    The Department of State, in comments on a subsequently 
proposed Senate interpretation suggested by the Chief of Staff 
of the Foreign Relations Committee, highlighted the issue as 
follows:
        * * * there is a very considerable difference between 
        the use of the term ``treaty'' in the Vienna Convention 
        and the generally accepted use of that term in the 
        internal law of the United States.
        * * * the term ``treaty'' under the internal law of the 
        United States is restricted to the term as used in 
        Article II, Section 2, of the Constitution.
        * * * the term treaty as used in our internal law does 
        not include international agreements made pursuant to a 
        treaty, international agreements authorized by 
        Congress, or international agreements made pursuant to 
        the President's constitutional authority [emphasis 
        added].\19\
---------------------------------------------------------------------------
    \19\ Letter dated January 31, 1974, Digest, 1974, supra note 14, at 
196. The text of the alternative interpretation and understanding, 
proposed on November 8, 1973, by Carl Marcy, the Chief of Staff of the 
Foreign Relations Committee at the time, would make any resolution of 
ratification ``subject to the interpretation and understanding, which 
understanding and interpretation are made a part and condition of the 
resolution of ratification, that within the meaning of Article 46 of 
the Convention, Article 2, Section 2, of the United States 
Constitution, stating that the President `shall have power, by and with 
the advice and consent of the Senate, to make treaties, provided two-
thirds of the Senators present concur,' is a rule of the internal law 
of the United States of fundamental importance'' [emphasis added].

    In 1984, Robert Dalton, Assistant Legal Adviser for Treaty 
Affairs, explained the department's objection to the 
interpretation and understanding proposed by the committee in 
1973 in the following way:
        * * * The Department was concerned that other countries 
        might conclude that, by making the interpretation and 
        understanding, the United States was intending to 
        abandon the practice of making executive agreements * * 
        *, or was attempting to avoid application of the 
        principle of pacta sunt servanda to those agreements by 
        reserving the possibility of invoking article 46 of the 
        Vienna Convention if it found the provisions of any 
        such agreement to be unduly onerous.\20\
---------------------------------------------------------------------------
    \20\ Robert E. Dalton, The Vienna Convention on the Law of 
Treaties: Consequences for the United States, in Proceedings of the 
American Society of International Law at its 78th Annual Meeting 277 
(1984).

    He stressed that the Vienna Convention had already 
influenced U.S. treaty practice in a number of ways, and that 
not being a party sometimes made it difficult to invoke the 
convention's rules in treaty relations with states that were 
parties.
    In the same forum, two former chief counsels of the Foreign 
Relations Committee supported becoming party to the convention, 
although both appeared to favor some kind of understanding to 
deal with the executive agreement issue. Frederick Tipson 
stressed the importance for the United States to follow through 
on negotiations after they had been concluded and treaties 
signed. But he also cited the need to clarify a number of 
important domestic constitutional procedures. In his view ``the 
United States could not afford to leave in limbo a series of 
important issues which remained outstanding between the 
Congress and the executive branch in the area of international 
agreements. Some effort should be made to remedy the situation 
by attempting to arrive at a consensus on several of these 
issues.'' \21\ Michael Glennon said the benefits of 
ratification outweighed the costs, and favored a ``stand-still 
provision'' that nothing in the convention should be construed 
as conferring any authority upon the President under U.S. law 
that he would not have had in its absence, along the lines of 
the earlier State Department proposal.\22\

    In 1986 the Foreign Relations Committee again held a 
hearing on the Vienna Convention on the Law of Treaties as well 
as several other treaties. Mary V. Mochary, Deputy Legal 
Adviser of the Department of State, spoke of the advantages of 
becoming a party to the treaty. She stressed the wide support 
for the convention in the academic and legal community, and the 
advantages of having a precise statement of customary law. She 
added, ``Moreover, the Convention includes procedural 
mechanisms for settlement of disputes that do not reflect 
customary law and cannot be invoked by the United States until 
it becomes a party to the convention.'' \23\

Senate Comm. on Foreign Relations, 99th Cong. (1986) (stenographic 
transcript of Hearing, June 11, 1986) (hereafter cited as Vienna

---------------------------------------------------------------------------
    On the issue of executive agreements, Arthur Rovine, a 
former Assistant Legal Adviser on Treaty Affairs for the 
Department of State and representing the American Bar 
Association, expressed the view that the Vienna Convention had 
fallen ``victim in the post-Vietnam and post-Watergate period 
to an attempt to limit the President's constitutional and 
statutory power to enter into international executive 
agreements.'' But in his view these were old issues having no 
bearing on the convention, and had been resolved by the Case-
Zablocki Act of 1972 on the reporting of all international 
executive agreements to Congress and related procedures on 
consultation on the form of an agreement.\24\

Zablocki Act, see Chapter X.
---------------------------------------------------------------------------
    At the hearing, Assistant Legal Adviser for Treaty Affairs 
Robert Dalton specified that the administration favored Senate 
advice and consent to the convention without reservation or 
understanding. In answer to supplementary written questions 
from the Foreign Relations Committee, the State Department 
reiterated its objections to the interpretation and 
understanding that had been proposed in 1972 by Senator Case. 
It argued that the proposed understanding would hamper the 
ability of the President to resolve international differences 
or undertake international cooperation by concluding agreements 
quickly, and that it would put the United States at a 
disadvantage in international negotiations by depriving it of 
the ability to make agreements with immediate binding effect to 
obtain and formalize concessions from other governments.\25\
---------------------------------------------------------------------------
    \25\ Vienna Convention, 1986 hearings. Answers to questions 
submitted by J. Edward Fox, Assistant Secretary, Legislative and 
Intergovernmental Affairs, July 24, 1986.
---------------------------------------------------------------------------
    The committee also submitted the question of whether the 
administration believed the U.S. constitutional requirement for 
advice and consent to be ``a rule of internal law of 
fundamental importance.'' The department replied the 
administration believed it was ``a rule of internal law of 
fundamental importance,'' enshrined in the Constitution. But, 
the department said, other relevant rules enshrined in the 
Constitution were also rules of fundamental importance, 
including the President's power as Commander-in-Chief, the 
executive power clause, and clauses relating to the reception 
of ambassadors and taking care that laws be faithfully 
executed. The department continued:
        If the resolution of advice and consent is to refer to 
        one rule of internal law of fundamental importance 
        relating to the conclusion of treaties as that term is 
        used in the Vienna Convention on the Law of Treaties, 
        it should also refer to the other relevant rules of 
        internal law. To draft such an understanding and 
        interpretation would require the preparation of a gloss 
        on the Constitution on which history shows it would be 
        exceedingly difficult for the executive branch and the 
        Congress as a whole promptly to agree. To fail to 
        include all the relevant rules would confuse foreign 
        countries and make it more difficult for the President 
        to exercise the full range of powers relating to 
        foreign affairs accorded to him under the 
        Constitution.\26\
---------------------------------------------------------------------------
    \26\ Ibid.

    Thus the Vienna Convention has become caught up in a long-
term controversy on the roles of the legislative and executive 
branches in the making of international agreements.

                          B. Treaty Definition

    The Vienna Convention establishes a comprehensive 
definition of a treaty in international law without prejudice 
to differing uses of the term ``treaty'' in the domestic laws 
of various states.\27\
---------------------------------------------------------------------------
    \27\ Vienna Convention, Art. 2, Sec. 2.
---------------------------------------------------------------------------
    Under the definition of a treaty provided by the Vienna 
Convention,
        treaty means an international agreement concluded 
        between states in written form and governed by 
        international law, whether embodied in a single 
        instrument or in two or more related instruments and 
        whatever its particular designation.\28\
---------------------------------------------------------------------------
    \28\ Vienna Convention, Art. 2, Sec. 1(a). Note also that the U.N. 
Charter employs the term ``treaty'' but does not define it. The 
charter, in Article 102, provides ``Every treaty and every 
international agreement entered into by any Member of the United 
Nations * * * shall * * * be registered with the Secretariat and 
published by it.'' Note further that the U.N. Secretariat ``follows the 
principle that it acts in accordance with the position of the Member 
States submitting an instrument for registration that so far as that 
party is concerned the instrument is a treaty or an international 
agreement within the meaning of Art. 2. Registration of an instrument 
submitted by a Member State, therefore, does not imply a judgment by 
the Secretariat on the nature of the instrument, the status of a party, 
or any similar question.'' See Leland Goodrich, Edvard Hambro, and Anne 
Patricia Simons, Charter of the United Nations 612 (3d ed. 1969).

    The Vienna Convention applies the term ``treaty'' to formal 
agreements designated as treaties and also to other agreements 
in simplified form, such as exchanges of notes. While the 
convention does not encompass unwritten agreements or 
agreements concluded with or by international organizations, it 
does not affect the validity of such agreements under 
international law.\29\
---------------------------------------------------------------------------
    \29\ Vienna Convention, Art. 3.
---------------------------------------------------------------------------

           C. Criteria for a Binding International Agreement

    A paramount principle of international law is pacta sunt 
servanda--that treaties must be kept. Treaties, therefore, are 
binding under international law. However, in the conduct of 
international relations, nations conclude business contracts or 
enter into understandings that fall short of being binding 
agreements with the status of international treaties.\30\ It 
is, therefore, vital to understand the elements that are 
necessary for an agreement to be considered a treaty under 
international law. Important criteria in determining this 
include: (1) the intention of the parties to be bound under 
international law, (2) the significance of the agreement, (3) 
the specificity of the agreement, and (4) the form of the 
agreement.
---------------------------------------------------------------------------
    \30\ The Department of State has compiled guidelines for internal 
purposes for determining the elements of a legally binding 
international agreement. The gist of these guidelines is: (1) The 
parties to an agreement must intend to be bound under international 
law. (2) The agreement must be of international significance and not 
deal with trivial matters. (3) The obligations undertaken must be 
clearly specified and be objectively enforceable. (4) The agreement 
must have two or more parties. (5) The agreement will preferably use a 
customary form. If not, content and context must reveal a legally 
binding intent. See Memorandum of March 12, 1976, from Monroe Leigh, 
Legal Adviser, Department of State, to all key Department personnel, 
reprinted in U.S. Department of State, Digest of United States Practice 
in International Law, 1976, 263-267 (1977) (hereafter cited as 
Department of State Memo of March 12, 1976). The memo stated that for 
``purposes of implementing legal requirements with respect to 
publication of international agreements and transmittal of 
international agreements to Congress, the Legal Adviser applies the * * 
* [above] criteria in deciding what constitutes an international 
agreement.'' These guidelines were subsequently incorporated in 
regulations designed to assist agencies in determining if agreements 
constitute international agreements within the meaning of the Case-
Zablocki Act. See 22 CFR part 181. The text of the regulations are 
contained in Appendix 3 of this volume.
---------------------------------------------------------------------------

      intention of the parties to be bound under international law

    So far as the U.S. State Department is concerned, treaties 
cannot be concluded unless the parties involved intend their 
acts to be legally binding.\31\ Documents that are intended to 
invoke purely political or moral obligations are not, 
therefore, treaties under international law. The Final Act of 
the Conference on Security and Cooperation in Europe (CSCE) or 
``Helsinki Accords'' adopted August 2, 1975, and most of the 
subsequent agreements concluded by the CSCE fall into this 
category.\32\ For example, the Vienna Document of March 4, 
1992, states in paragraph 156: ``The measures adopted in this 
document are politically binding and will come into force on 1 
May 1992.'' \33\

---------------------------------------------------------------------------
    Furthermore, a binding international agreement must be 
subject to international law and not the law of another legal 
system. For example, if an agreement specifies that it is to be 
governed by the law of a particular nation, the mention of 
governing domestic law would probably be construed as negating 
an intent to be bound by international law. To illustrate this 
point, the State Department notes that a (hypothetical) foreign 
military sales contract, specifying that it is governed by the 
law of the District of Columbia, is not a binding international 
agreement.\34\ Although many international agreements are 
silent as to which law governs them, the intent of the makers 
normally is that international law apply.\35\

    This element--that the parties must intend an agreement to 
be legally binding under international law--is incorporated 
into the definition of an international agreement in the 
Restatement (Third) of the Foreign Relations Law of the United 
States. The Restatement, while lacking the force of formally 
enacted law, has been cited as evidence of the law in the 
decisions of U.S. courts.\36\ The Restatement defines an 
international agreement in the following manner:
---------------------------------------------------------------------------
    \36\ See, for example, Dames & Moore v. Regan, 453 U.S. 654, 680 
(1981). Rest. 3d, Sec. 301(1) (1987). The Restatement (Third) was 
adopted and promulgated by the American Law Institute (a private 
organization) on May 14, 1986. The ``Restatement represents the opinion 
of the American Law Institute as to the rules that an impartial 
tribunal would apply if charged with deciding a controversy in 
accordance with international law.'' Ibid., at 3.
---------------------------------------------------------------------------
        ``International agreement'' means an agreement between 
        two or more states or international organizations that 
        is intended to be legally binding and is governed by 
        international law; * * *.\37\
---------------------------------------------------------------------------

---------------------------------------------------------------------------

                              significance

    To have the status of a treaty under international law, an 
agreement should concern itself with significant matters. It 
cannot deal with trivial matters alone, even if they are 
couched in legal language and form.\38\ The significance of an 
agreement is frequently characterized as a matter of degree. 
For example, ``a promise to sell one map to a foreign nation is 
not an international agreement; a promise to sell one million 
maps probably is * * *.'' \39\ The exact point, however, 
between 1 and 1 million maps at which the transaction becomes 
an international agreement is difficult to determine. Since 
there are no detailed guidelines to assist in deciding the 
level of significance needed, the answer is largely a matter of 
judgment within the context of a particular transaction.\40\

    \40\ See Arthur Rovine, Separation of Powers and International 
Agreements, 52 Ind. L. J. 402-403 (1950). Note also that the Department 
of State provides some guidance in a letter of September 6, 1973, from 
Acting Secretary of State Kenneth Rush to Secretary of Defense James R. 
Schlesinger. This letter requires transmittal to the State Department 
[for possible transmittal to the Congress] of ``* * * any agreements of 
political significance, any that involve a substantial grant of funds, 
any involving loans by the United States or credits payable to the 
United States, any that constitute a commitment of funds that extends 
beyond a fiscal year or would be a basis for requesting new 
appropriations, and any that involve continuing or substantial 
cooperation in the conduct of a particular program or activity, such as 
scientific, technical, or other cooperation, including the exchange or 
receipt of information and its treatment.'' For the full text of the 
letter, see Congressional Oversight of Executive Agreements: Hearing 
Before the Subcommittee on Separation of Powers, Senate Committee on 
the Judiciary, 94th Cong. 101 (1975). As noted above, the meaning of 
the term ``treaty'' under the U.S. Constitution and domestic laws is 
narrower than its meaning under international law. A number of 
``executive agreements'' under domestic laws would qualify as treaties 
under international law, but not all agreements concluded by the 
executive branch have the significance sufficient to be considered 
treaties under international law. The guidelines in the Department of 
State letter are meant to enable executive branch agencies to determine 
which executive agreements qualify as treaties under international law 
and therefore must be reported to Congress.
---------------------------------------------------------------------------

                              specificity

    A treaty should clearly and specifically describe the 
obligations legally assumed by the parties.\41\ This requires 
that the terms setting out the obligations assumed by parties 
be worded specifically, so that an observer can determine 
fairly objectively whether a party is legally bound. Thus, 
international diplomatic undertakings which do not specifically 
describe precise legal obligations, are not legally binding. An 
example would be a promise ``to help develop a more viable 
economic system.'' In contrast, a promise to deliver 1,000 
tractors of a specified type, for a specified amount of money, 
to be delivered at a specified place, on a specific date, sets 
forth the definable obligations necessary to make such a 
promise legally binding.
---------------------------------------------------------------------------
    \41\ Department of State Memo of March 12, 1976, supra note 30, at 
266.
---------------------------------------------------------------------------
    This does not mean, however, that every provision of a 
treaty must meet this criterion of specificity in order for the 
treaty to be legally binding. In fact, treaties often contain 
individual clauses which describe in non-specific terms 
obligations assumed by the parties.

                         form of the agreement

    Form is not central to the validity of a binding 
international agreement, but it may reflect the intention of 
the parties to conclude an agreement, or something less than an 
agreement.\42\ Thus, in all probability a formal document 
entitled ``agreement''--one with final clauses, signature 
blocks, entry into force dates, and dispute settlement 
provisions--would reflect a general intent to conclude an 
international agreement.
---------------------------------------------------------------------------
    \42\ Ibid. Also, the International Court of Justice has 
consistently stated that form ``* * * is not a domain in which 
international law imposes any special or strict requirements.'' Nuclear 
Tests case (Austl. v. Fr.), 1974 I.C.J. 253, 267-268 (Dec. 20).
---------------------------------------------------------------------------
    It is emphasized that the substance, and not the form, of 
the agreement determines whether it is a treaty. Occasionally, 
however, the failure to follow a customary form to conclude an 
agreement may constitute evidence of an intent not to be 
legally bound. In such cases, it is important to determine 
whether the general content of the agreement and the context of 
its making reveal an intent to be legally bound; if so, the 
lack of a customary or proper form will not be decisive. 
Moreover, if an agreement is the product of formal 
international negotiations by diplomats, this may be construed 
as supporting evidence of an intent to be legally bound.\43\
---------------------------------------------------------------------------
    \43\ Department of State Memo of March 12, 1976, supra note 30 at

---------------------------------------------------------------------------
    Inasmuch as the substance, not the form, governs the 
validity of an international agreement, it is possible to have 
binding agreements that are not in writing, although in 
practice this rarely occurs. Hence, ``whether a statement is 
made orally or in writing makes no essential difference * * 
*.\44\ The Vienna Convention does not apply to binding oral 
agreements, but as a matter of practice, international 
agreements are usually in written form.\45\
---------------------------------------------------------------------------
    \44\ Nuclear Tests cases at 267. Although the Vienna Convention 
applies only to instruments in written form (Art. 2(1)(a)), it does not 
affect the validity of unwritten agreements (Art 3). Under customary 
international law, oral agreements are just as binding as written ones.

    A wide variety of descriptive terms may be used to describe 
international agreements, but these terms do not in themselves 
determine whether an agreement has the status of a treaty. They 
may, nevertheless, be considered a factor among others in 
determining whether the parties intend to create an 
internationally legally binding agreement. Relevant terms 
include treaty, convention, protocol, declaration, agreement, 
act, covenant, statute, concordat, exchange of notes, 
memorandum of agreement, memorandum of understanding, modus 
vivendi or charter.\46\ Often there is no apparent reason for 
the use of one title as opposed to another, and the choice is 
frequently the result of non-legal considerations.

  D. Limitations on Binding International Agreements and Grounds for 
                              Invalidation

    International law does not limit the subject matter of 
international agreements. However, many theorists of 
international law argue that certain principles of 
international law cannot be violated by a treaty without 
rendering a treaty void. Thus, it would be widely agreed that a 
pact of aggression between two states against a third state 
could not have the force of international law as it would 
violate norms in the U.N. Charter prohibiting the use of force 
except in self defense.\47\ Other circumstances enable a 
signatory to invalidate a treaty if it chooses to do so. For 
example, an error made by a state concluding a treaty, which 
formed an essential basis of its consent to be bound, would 
permit that state to invoke the error to invalidate the treaty.
---------------------------------------------------------------------------
    \47\ U.N. Charter, Art. 2, Sec. 4, and Art. 51. See Georg 
Schwarzenberger and E.D. Brown, A Manual of International Law 24 (6th 
ed. 1976).
---------------------------------------------------------------------------
    If principles are violated which make a treaty void, the 
treaty cannot be in effect--or ever have been in effect--and 
there can be no question of seeking redress for violating it. 
However, some grounds for invalidity are voidable, that is, the 
aggrieved state has the option of maintaining the treaty in 
force or declaring it invalid.

          invalidation by fraud, corruption, coercion or error

    Consent is necessary for a state to be bound by a treaty 
\48\ and it may be expressed in many ways.\49\ Since consent 
implies a voluntary decision, it can be negated by coercion, 
fraud, and corruption of agents who are giving authorized 
consent for their state. Consent of a state to be bound by a 
treaty may also be negated by error.\50\

    \50\ Vienna Convention, Art. 48, and Rest. 3d, Sec. 331(1)(a).
---------------------------------------------------------------------------
    Current international rules relating to coercion, fraud and 
corruption as a basis for invalidating consent to a treaty have 
been summarized in the Restatement (Third) as follows:
        (1) A state may invoke only the following grounds to 
        invalidate its consent to be bound by an agreement:
                (a) an error as to a fact or situation which 
                was assumed by that state to exist at the time 
                of the agreement and which formed the basis of 
                its consent to be bound.\51\
---------------------------------------------------------------------------
    \51\ Rest. 3d, Sec. 331. The wording of this section essentially 
follows that of the Vienna Convention which lists ``error'' as a ground 
that may be invoked to invalidate consent to be bound (Art. 48). Such 
error must relate ``to a fact or situation which was assumed by that 
State to exist at the time when the treaty was concluded and formed an 
essential basis of its consent to be bound.'' However, under the Vienna 
Convention, a state may not invoke error if it contributed to the error 
by its own conduct or if circumstances were such as to put the state on 
notice of a possible error (Art. 48(2)). Also, error in the wording of 
an agreement, such as a typographical error, is not a ground for 
invalidating it; special procedures are established for the correction 
of such errors. Vienna Convention, Articles 48(3) and 79. See Rest. 3d, 
Sec. 331, Comment b.
---------------------------------------------------------------------------
                (b) the fraudulent conduct of another 
                negotiating state that induced its consent; or
                (c) the corruption of the state's 
                representative by another negotiating state.
        (2) An international agreement is void
                (a) if a state's consent to the agreement was 
                procured by the coercion of the state's 
                representative, or by the threat or use of 
                force against the state in violation of the 
                principles of international law embodied in the 
                Charter of the United Nations; * * *.\52\
---------------------------------------------------------------------------
    \52\ Rest. 3d, Sec. 331. This section combines and follows the rule 
stated in the Vienna Convention in Arts. 49-53.
---------------------------------------------------------------------------

      invalidation by conflict with a peremptory norm of general 
                     international law (jus cogens)

    Traditionally, many theorists of general international law 
have argued that there exists a jus cogens or superior law 
which holds a special status internationally and which cannot 
be violated by a treaty.\53\ Although legal theorists differ as 
to which international rules currently have the status of jus 
cogens, they tend to agree that attainment of this status is 
largely the result of an evolutionary process. Notwithstanding 
uncertainty as to what rules are, and what rules may become, 
jus cogens, the Vienna Convention accords recognition to the 
concept of such rules.
---------------------------------------------------------------------------
    \53\ See Georg Schwarzenberger and E.D. Brown, A Manual of 
International Law 24 (6th ed. 1976).
---------------------------------------------------------------------------
    The principle of jus cogens \54\ holds that an 
international agreement is void if at its inception it 
conflicts with a peremptory norm of general international 
law.\55\ The Vienna Convention in Article 53 defines a 
``peremptory norm of general international law'' as:
---------------------------------------------------------------------------
    \54\ Compelling law which is binding on parties regardless of their 
will and will not yield to other laws.
    \55\ Vienna Convention, Art. 53, Rest. 3d, Sec. 331(2)(b) and 
Comment e.
---------------------------------------------------------------------------
        * * * a norm from which no derogation is permitted and 
        which can be modified only by a subsequent norm of 
        general international law having the same character.

    These norms are rules commonly accepted as holding a 
superior status and which therefore cannot be affected by a 
treaty. Thus, a norm cannot be jus cogens unless the 
international community accepts both the norm and its 
peremptory character. Under the convention, the emergence of a 
new peremptory norm voids any treaty provision violating the 
new norm.\56\
---------------------------------------------------------------------------
    \56\ However, the emergence of a new rule of jus cogens will not 
have retroactive effect on the validity of a treaty. Accordingly, the 
invalidity will only attach from the time the new rule is established. 
See Vienna Convention, Art. 64; International Law Commission Report, 61 
Am. J. Int'l L. 412 (1967).
---------------------------------------------------------------------------
    It is accepted that certain obligations of member states 
under the U.N. Charter constitute jus cogens.\57\ Thus, the 
example provided earlier, of an aggression pact between two 
states against a third which provides that their two armies 
will jointly invade the third state, subjugate it, and jointly 
rule it, is generally accepted as violating a jus cogens rule 
against the use of aggressive force.\58\ There is, however, 
substantial uncertainty as to what other norms are peremptory 
and therefore constitute jus cogens. Some interpretations of 
peremptory norms might include ``rules prohibiting genocide, 
slave trade and slavery, apartheid and other gross violations 
of human rights, and perhaps attacks on diplomats.'' \59\
---------------------------------------------------------------------------
    \57\ Rest. 3d, Sec. 331, Reporters' Note 5. Art. 103 of the U.N. 
Charter provides that if there is a conflict between member obligations 
under the Charter and their obligations under another international 
agreement, the Charter shall prevail.
    \58\ See Rest. 3d, Sec. 102, Comment k and Reporters' Note 6.
    \59\ See Rest. 3d, Sec. 702(a)-(f), Comment n and Reporters' Note 
6.
---------------------------------------------------------------------------
    When a treaty at its inception is void because it conflicts 
with a peremptory norm (Article 53), the parties are expected 
to comply with the norm (Article 71). If a treaty becomes void 
because a new overriding norm has emerged (Article 62), the 
parties are released from any further obligation to 
perform.\60\
---------------------------------------------------------------------------
    \60\ Vienna Convention, Art. 71, Comment a.
---------------------------------------------------------------------------
    Because uncertainty may exist as to whether a particular 
norm constitutes a rule of jus cogens, the issue of who decides 
such claims when nations invoke Article 53 in an attempt to 
invalidate agreements becomes of paramount importance. Thus, 
the U.S. Government, in its comments on an earlier Draft 
Article 37 of the International Law Commission, similar to 
Article 53, relating to the emergence of new norms, noted that 
such an article ``could not be accepted unless agreement is 
reached as to who is to define a new peremptory norm and to 
determine how it is to be established.'' \61\ The text of the 
article was amended by the conference in such a way as to give 
the United States, in the view of State Department officials, a 
veto over creation of a new peremptory norm. The final text 
defined such a norm as one ``accepted and recognized by the 
international community of States as a whole.''

the Law of Treaties, U.N. Doc. A/CN.4/183 and Add.1-4, reprinted in

---------------------------------------------------------------------------
     In addition, under another article, any party to a dispute 
arising under the jus cogens article may invoke the 
jurisdiction of the International Court of Justice unless the 
parties agree to submit to arbitration.\62\ This International 
Court dispute settlement provision, it is argued, protects the 
United States against arbitrary jus cogens claims which other 
states might attempt to use as a basis for invalidating 
treaties with the United States. The Senate on occasion has 
expressed concern about treaty provisions requiring submission 
of disputes to arbitration or the International Court, but on 
numerous occasions has given unqualified approval to such 
treaties.\63\

      invalidation by violation of domestic law governing treaties

     In the world community, constitutional limitations 
affecting the exercise of the treatymaking power differ from 
nation to nation.\64\ International law generally provides that 
a state may not invalidate a treaty because of claims that its 
consent to be bound has been expressed in violation of domestic 
law governing its competence to conclude a treaty. Article 
46(1) of the Vienna Convention, permits a state to invalidate a 
treaty if a violation of domestic law was ``manifest and 
concerned a rule of its internal law of fundamental 
importance'' [emphasis added]. Article 46(2) further provides 
that a violation is manifest ``if it would be objectively 
evident to any State conducting itself in the matter in 
accordance with normal practice and in good faith.''
---------------------------------------------------------------------------
    \64\ For example, the British system has been described in the 
following way: ``It is a truism that in the United Kingdom it is the 
Crown alone, that is to say the executive and without reference to 
Parliament, which has the exclusive responsibility for the negotiation, 
conclusion, and termination of treaties. In other words, treaty making 
forms part of what we call the royal prerogative. If the implementation 
of a treaty requires a change in domestic law or the conferment of new 
powers upon the executive, the government of the day will of course 
have to secure the passage through Parliament of the necessary enabling 
legislation. This will normally be done during the period between 
signature and ratification of the treaty, since otherwise there would 
be the risk that the United Kingdom's domestic law would not permit 
full effect to be given to the treaty as and when it entered into 
force.'' Sir Ian Sinclair (Legal Adviser, Foreign and Commonwealth 
Office, United Kingdom, 1976-1984), Vienna Convention on the Law of

     These provisions have been of interest to the U.S. Senate 
primarily because of the question whether they could prevent 
the United States from being internationally bound by an 
instrument which the President signed as an executive 
agreement, but which arguably should have been sent for Senate 
advice and consent.\65\ In the words of one constitutional 
authority:
---------------------------------------------------------------------------
    \65\ See discussion under section, Senate Action on the Convention, 
earlier in this chapter, which includes the texts of Senate 
interpretations and understandings to the Vienna Convention proposed in 
1972 and 1973.
---------------------------------------------------------------------------
        A(n) * * * issue is whether under international law the 
        United States could ever claim it was not bound by an 
        agreement because it was made without Senate consent. 
        Whether a state can escape obligation on the ground 
        that those who incurred it in her behalf acted ultra 
        vires under the national constitution is not wholly 
        agreed. * * * Art. 46(1) of the Vienna Convention on 
        the Law of Treaties * * * provides that a state cannot 
        invoke failure to comply with its internal law as a 
        defense ``unless that violation was manifest and 
        concerned a rule of its internal law of fundamental 
        importance.'' Senate consent has been cited as an 
        example of a fundamental requirement. * * * But the 
        power of the President to make many agreements without 
        the Senate casts some doubt on the ``fundamental 
        importance'' of Senate consent; in any event, failure 
        to obtain such consent cannot be a ``manifest'' 
        violation of the Constitution since no one can say with 
        certainty when it is required. [Citations omitted] \66\

     The potential ramifications of this problem were not 
addressed by Secretary of State William P. Rogers, when in his 
letter submitting the Vienna Convention to the President [for 
transmittal to the Senate], he referred to Article 46 and the 
effect of a limitation of domestic law upon a state's 
competence to conclude treaties. The Secretary noted generally 
that the U.S. delegation supported Article 46 on the basis 
that:
        * * * it deals solely with the conditions under which a 
        state may invoke internal law on the international 
        plane to invalidate its consent to be bound and that in 
        no way impinges on internal law regarding competence to 
        conclude treaties insofar as domestic consequences are 
        concerned.\67\

     This issue was, however, addressed by the Restatement 
(Third) which commented that:
        Presumably, a manifest violation might involve either 
        procedural irregularities or a contravention of 
        substantive prohibitions or requirements of domestic 
        law. As to the United States, all states may be 
        presumed to know that the President of the United 
        States cannot make a treaty without the consent of the 
        Senate. * * * The President has authority, however, to 
        make many international agreements pursuant to treaty 
        or congressional authorization * * *, or on his own 
        authority * * *, and since the circumstances in which 
        Senate consent is essential are uncertain, improper use 
        of an executive agreement in lieu of a treaty would 
        ordinarily not be a ``manifest'' violation. * * * Some 
        agreements, such as the United Nations Charter or the 
        North Atlantic Treaty, are of sufficient formality, 
        dignity, and importance that, in the unlikely event 
        that the President attempted to make such agreement on 
        his own authority, his lack of authority might be 
        regarded as ``manifest.'' \68\
---------------------------------------------------------------------------
    \68\ Rest. 3d, Sec. 311, Comment c.

     A somewhat similar position on what constitutes a 
``manifest'' violation of a nation's domestic law governing 
competence to conclude treaties was taken by the International 
Law Commission (a body of 25 legal scholars elected by the U.N. 
General Assembly) in its Commentary on its Final Draft of the 
Vienna Convention. The commission noted that differing 
viewpoints exist on the issue of whether or not an agent who is 
competent under international law to commit a state--but 
perhaps not authorized to do so under domestic law--and who 
expresses state consent to a treaty by an established 
international procedure in fact binds the state to the treaty 
under international law. In response to this issue, the 
commission noted that decisions of international tribunals, 
together with state practice, appear to support a position 
holding that failure of an agent to comply with domestic 
requirements does not affect the validity of the treaty under 
international law.\69\
---------------------------------------------------------------------------
    \69\ Such failure, however, may limit that state's power to enforce 
a treaty and may also render the agent liable to legal consequences 
under domestic law. For supporting citations, see Travaux 
Preparatoires, pp. 336-338 (1978). See also United Nations, Reports of 
the International Law Commission on the Second Part of its Seventeenth 
Session, January 3-28, 1966, and on Its Eighteenth Session, May 4-July 
19, 1966, 61 American Journal of International Law 394-400 (1967).
---------------------------------------------------------------------------
     A different position was taken in 1975 by the Office of 
the Legislative Counsel of the Senate. The office suggested 
that if a state should reasonably have known of a 
constitutional defect in an agreement with the United States, 
that is, that certain agreements are ``beyond the power of the 
President to enter into without the advice and consent of the 
Senate,'' then such an agreement would be without force and 
effect under international law. Its memorandum noted that under 
international law, as evidenced in many sources including the 
Vienna Convention:
        (1) a State may be bound, under international law, by 
        an agreement made in violation of its constitutional 
        process;
        (2) a State is not bound if (A) such violation is 
        fundamental; and (B) the other party to such agreement 
        should reasonably have known of the constitutional 
        defect;
        (3) such State is bound, however, if its subsequent 
        conduct indicates acquiescence in the validity of the 
        agreement.\70\

    \70\ Memorandum of September 24, 1975, from Michael J. Glennon, 
Assistant Counsel, Office of the Legislative Counsel, U.S. Senate, 
regarding a memorandum of agreement between the United States and 
Israel, dated September 1, 1975. The agreements and assurances in 
question were made by the United States in connection with the Egypt-
Israel disengagement agreement of September 4, 1975. See Early Warning 
System in Sinai: Hearings before the Senate Committee on Foreign 
Relations, 94th Cong. 79 (1975). Excerpts from the Senate Legislative 
Counsel's memo are reproduced in U.S. Department of State, Digest of 
United States Practice in International Law, 1975, 320 (1976) 
(hereafter cited as Digest, 1975). See also section, ``Senate Action on 
the Convention,'' earlier in this chapter for views on the Vienna 
Convention expressed by Mr. Glennon in 1984.

     This memorandum asserts a Senate viewpoint that other 
nations should ``reasonably know'' of constitutional defects 
such as the lack of Senate advice and consent to certain 
agreements, and that in some instances the Senate might 
maintain the agreement is invalid under international law.\71\
---------------------------------------------------------------------------
    \71\ Note that whereas Art. 46 of the Vienna Convention describes a 
``manifest'' violation in terms of ``being objectively evident to any 
state,'' the memorandum above employs the standard when states ``should 
reasonably have known'' of a constitutional defect [emphasis added]. 
Nevertheless, it is the President who voids an executive agreement, and 
not the Senate.
---------------------------------------------------------------------------
     The issues discussed above resulted from the Vienna 
Convention's lack of clarification of the circumstances which 
permit a state to invalidate a treaty (under the rare and 
exceptional circumstances when a manifest violation of a 
state's internal law regarding competence to conclude treaties 
might occur).\72\ Thus Article 46 has been an issue in the 
consideration of the convention by the Senate Foreign Relations 
Committee, discussed above.
---------------------------------------------------------------------------
    \72\ See Section A above, The Vienna Convention on the Law of 
Treaties. However, because the internal laws of states vary in their 
requirements for invalidation of a treaty, it would be difficult for 
the Vienna Convention to provide more specificity in this area. 
Furthermore, the internal laws of a country may not even been clear on 
this issue. In the United States, for example, ``[t]he Supreme Court 
has not held any executive agreement to be ultra vires the President 
and * * * has upheld several agreements of particular character, but it 
has not laid down principles or given general guidance to define the 
President's power to act alone.'' See Louis Henkin, Foreign Affairs and 
the United States Constitution, supra note 66, note at 222.

          E. Non-Binding Agreements and Functional Equivalents

     A non-binding international agreement is one that does not 
meet the previously stated criteria for a binding international 
agreement.\73\ Non-binding agreements do not convey an 
intention of the parties to create legally committing 
relationships under international law. Often such documents 
convey merely a present intention to perform an act or a 
commitment of a purely personal, political, or moral 
nature.\74\ The Helsinki Agreement mentioned above, for 
example,\75\ avoids words of legal commitment and states that 
it is not eligible for registration as a treaty in force under 
Article 102 of the U.N. Charter.\76\
---------------------------------------------------------------------------

International Agreement.

---------------------------------------------------------------------------
     Non-binding agreements may take many forms, including 
unilateral commitments and declarations of intent, joint 
communiques and joint statements (including final acts of 
conferences), and informal agreements. Even when agreements are 
legally non-binding, the parties affected may to some degree 
expect adherence.
     The Department of State described the difference between a 
legally binding obligation and a political obligation in 
describing certain declarations, intended to be politically 
rather than legally binding, exchanged in connection with the 
START Treaty:
        An undertaking or commitment that is understood to be 
        legally binding carries with it both the obligation of 
        each Party to comply with the undertaking and the right 
        of each Party to enforce the obligation under 
        international law. A ``political'' undertaking is not 
        governed by international law and there are no 
        applicable rules pertaining to compliance, 
        modification, or withdrawal. Until and unless a Party 
        extricates itself from its ``political'' undertaking, 
        which it may do without legal penalty, it has given a 
        promise to honor that commitment, and the other Party 
        has every reason to be concerned about compliance with 
        such undertakings. If a Party contravenes a political 
        commitment, it will be subject to an appropriate 
        political response.\77\

            unilateral commitments and declarations of intent

     Unilateral commitments and related instruments such as 
unilateral declarations of intent cannot constitute 
international agreements in the strict sense because an 
agreement, by definition, requires at least two parties.\78\ 
For example, a unilateral commitment or declaration in the form 
of a promise to send money to a country to help earthquake 
victims, but without reciprocal commitments on the part of the 
other country, would be a promise of a gift and not an 
international agreement.
---------------------------------------------------------------------------
    \78\ Department of State Memo of March 12, 1976, supra note 30, at 
266.
---------------------------------------------------------------------------
     Situations do exist, however, under which unilateral 
commitments or declarations of intent may become binding 
international agreements. Such instances involve parallel 
unilateral undertakings by two or more states that are 
unilateral in form but which in content constitute bilateral or 
multilateral agreements. Such reciprocal unilateral 
declarations occur regularly in international relations.\79\
---------------------------------------------------------------------------
    \79\ Rest. 3d, Sec. 301, Reporters' Note 3, which supports the 
premise that ``reciprocal'' unilateral declarations that accept the 
compulsory jurisdiction of the International Court of Justice under 
Article 26 of the Court's Statute have been held by that court to 
constitute an international agreement among the declaring states. See 
Anglo-Iranian Oil cases (U.K. v. Iran), 1952 I.C.J. 93 (July 22).
---------------------------------------------------------------------------
     It should be noted that in one important set of cases a 
unilateral commitment was held legally binding upon the party 
making it, even though it was not made in a multilateral 
context. Such a finding was reached by the International Court 
of Justice in the Nuclear Tests cases.\80\ In these cases, the 
International Courts ruled that a series of unilateral 
declarations by France concerning its intention to refrain from 
future atmospheric nuclear testing in the South Pacific was 
legally binding upon France. The sense of the Court's holding 
was that publicity and an intent to be bound are sufficient in 
such an instance to give rise to a legal obligation. In the 
words of the Court:
---------------------------------------------------------------------------
    \80\ Nuclear Tests case (Austl. v. Fr.), 1974 I.C.J. 253, 267-268 
(Dec. 20), and Nuclear Tests case (N.Z. v. Fr., 1974 I.C.J. 457 (Dec. 
20).
---------------------------------------------------------------------------
          It is well recognized that declarations made by way 
        of unilateral acts * * * may have the effect of 
        creating legal obligations. Declarations of this kind 
        may be, and very often are, very specific. When it is 
        the intention of the State making the declaration that 
        it should become bound * * * that intention confers on 
        the declaration the character of a legal undertaking * 
        * *. An undertaking of this kind, if given publicly, 
        and with an intent to be bound, even though not made 
        within the context of international negotiations, is 
        binding * * *. Just as the very rule of pacta sunt 
        servanda in the law of treaties is based on good faith, 
        so also is the binding character of an international 
        obligation assumed by unilateral declaration. Thus, 
        States may take cognizance of unilateral declarations 
        and place confidence in them, and are entitled to 
        require that the obligations thus created be 
        respected.\81\

and 49 (N.Z. v. Fr.). See also S. Rubin, The International Legal 
Effects of Unilateral Declarations, 71 Am. J. Int'l. L. 1-30 (1977).

     The International Court's decision in this matter, 
although binding only on the parties in these particular 
cases,\82\ is problematic to legal analysts because it runs 
contrary to the legal principles that have traditionally 
governed such unilateral pronouncements or statements of 
intent.\83\ Moreover, the analysts argue, among other things, 
that governments are unlikely to accept the view that their 
policy pronouncements are binding. If such pronouncements are 
subject to interpretation as legal commitments by the 
International Court, some observers point out that few states 
would submit to its jurisdiction.\84\

                 joint communiques and joint statements

     Joint statements of intent are not binding agreements 
unless they meet the requirements of legally binding 
agreements, that is, that the parties intend to be legally 
bound. As in the case with all agreements, the substance and 
not the title is dispositive. Thus, whether or not a joint 
statement is titled a ``joint statement'' or ``joint 
communique'' or ``declaration'' has no effect on whatever legal 
standing it may hold independent of its title.\85\
---------------------------------------------------------------------------
    \85\ The way an instrument is dealt with after its conclusion may 
be an indication of whether it is intended to have legal effect. For 
example, it may be published in a national treaty collection, or it may 
be registered under Art. 102 of the U.N. Charter, or it may be 
described as a treaty during submission to a national parliament.
---------------------------------------------------------------------------
     An important non-binding agreement was the communique and 
joint statement issued by the United States and the U.S.S.R. 
reaffirming their intention not to take action inconsistent 
with the interim strategic arms limitation agreement that 
expired in 1977. The Department of State and the counsel to the 
Senate Foreign Relations Committee both found that this 
communique and statement did not constitute an international 
agreement. In the words of then-committee counsel, Michael J. 
Glennon: ``It [the statement] is nonbinding, it is not governed 
by international law, no exchange of promises has been 
bargained, other such actions have not been so construed, and 
the parties do not intend for an agreement to exist--indeed, 
there are no `parties' as such.'' \86\ Another example is the 
Bonn Declaration of July 17, 1978. This declaration was issued 
after an economic summit which was held at Bonn, West Germany, 
July 16 and 17, 1978, and was subscribed to by the leaders of 
seven nations including the United States.\87\ The declaration, 
which summarized the problems discussed in the summit meeting 
and stated the commitments agreed to be necessary for their 
resolution, prompted a request from the Chairman of the Senate 
Foreign Relations Committee to the Department of State 
regarding its legal significance. The reply from the State 
Department read in part:
---------------------------------------------------------------------------
    \86\ See U.S. Department of State, Digest of United States Practice 
in International Law, 1977, 429 (1978) (hereafter cited as Digest, 
1977).
    \87\ The nations were Canada, France, West Germany, Italy, Japan, 
the United Kingdom, and the United States. See Digest, 1977, supra note 
86, at 799-800.
---------------------------------------------------------------------------
        While the Declaration issued in Bonn is an important 
        political commitment, it is not an international 
        agreement within the meaning of United States law or 
        international law since the parties did not evidence an 
        intent to depart from the established international 
        practice of concluding non-binding communiques at the 
        conclusion of a summit meeting. Accordingly, while we 
        expect that the Bonn summit participants will comply 
        with the accord, it is not a legally binding 
        commitment.\88\

---------------------------------------------------------------------------

                           informal agreements

     In contrast to the calculated ambiguity of many non-
binding declarations and agreements, governments may enter into 
precise and definite understandings that are clearly intended 
to affect their relations with each other, but with a clear 
understanding that agreements are not legally binding. Such 
informal agreements were formerly called ``gentlemen's 
agreements.'' \89\
---------------------------------------------------------------------------
    \89\ Rest. 3d, Sec. 301, Comment e.
---------------------------------------------------------------------------
     Informal agreements may be made by heads of state or 
government, by foreign ministers, or by other authorized 
officials. In these cases, the parties generally assume a 
commitment to perform or refrain from certain acts. Although 
the commitments are regarded as non-legal, there is 
nevertheless an expectation of performance by the parties.\90\
---------------------------------------------------------------------------
    \90\ See Oscar Schachter, The Twilight Existence of Nonbinding 
International Agreements, 71 Am. J. Int'l. L., 296, 299 (1977).
---------------------------------------------------------------------------
     An example is a 1908 agreement between the U.S. and 
Japanese foreign ministers whereby the Japanese Government 
agreed to take administrative measures to limit the emigration 
of Japanese laborers to the United States. This was done with 
the understanding that the United States, in return, would not 
adopt discriminatory exclusionary legislation against Japanese 
citizens. The agreement terminated when the Congress enacted 
the 1924 immigration law that discriminated against 
Japanese.\91\ More recent examples would include voluntary 
restraints agreed to by governments in the trade field.

---------------------------------------------------------------------------
     Even though states do not accept legal responsibility for 
non-binding commitments such as informal agreements, a state 
may choose to regard a non-binding undertaking as a controlling 
one. It may do so even though the affected parties generally 
have no legal remedy or sanctions for breaches of such 
commitments. The failure to abide by an informal agreement may 
have political consequences, however, possibly including 
countermeasures.

                    status of non-binding agreements

     Although legally not enforceable, non-binding agreements 
and unilateral commitments are useful to states in meeting 
certain needs. The need for flexibility--for keeping options 
open--is common to most governments and help to make non-
binding agreements attractive to them. Non-binding agreements 
provide a recognized procedural means for a state to exercise 
this flexibility.
     Often, non-binding agreements or commitments are used by 
states to signal broad policy guidelines which may be subject 
to change. Or, they may amount to nothing more than a 
propaganda ploy enabling a state to declare support for a 
policy it has no intention of following.
     Another reason for a state entering into non-binding 
agreements may be a desire to avoid legal remedies in the event 
of non-compliance, even though it intends to comply. Non-
binding agreements are well suited to such a role because that 
may relate to a very specific matter and may involve clear 
promises of intent and goodwill with expectations of reliance 
on them by all involved parties. And, if for some reason it is 
not possible to honor such an agreement, the aggrieved party 
may well have to pursue political rather than legal remedies.
     Non-binding agreements also permit a head of state or his 
agent to make commitments with the intention of honoring them, 
but without the need of going through what may be perceived as 
a cumbersome constitutional approval or reporting process 
reserved for binding agreements.\92\ Government officials may 
go on the record as expressing their intent to honor non-
binding commitments. For example, Secretary of State Kissinger, 
while testifying before the Senate Foreign Relations Committee 
regarding U.S. undertakings in connection with the Sinai 
Disengagement Agreements of 1975, noted that some of the 
undertakings were ``not binding commitments of the United 
States * * * [but that] does not mean, of course, that the 
United States is morally or politically free to act as if they 
did not exist. On the contrary, they are important statements 
of diplomatic policy and engage the good faith of the United 
States as long as the circumstances that gave rise to them 
continue.'' \93\ Supplemental statements of this type, however, 
do not affect the non-binding character of the commitment to 
which they relate.

    \92\ Rest. 3d, Sec. 301, Reporters' note 2.
    \93\ See 73 Dep't St. Bull. 613 (1975).
---------------------------------------------------------------------------
     As nations use non-binding agreements for different 
reasons, it is important to examine the motive for making a 
particular agreement non-binding, the context within which it 
is made, the wording and intent of the commitment as expressed 
by the language used, and the reputation and history of the 
state or representative for honoring such statements. Only by 
evaluating such criteria can a government arrive at realistic 
expectations as to whether or not the parties will comply with 
such commitments.
     In conclusion, international agreements having the status 
of treaties clearly show an intent by the parties to be bound 
under international law. They describe specific legal 
obligations which the parties assume and deal generally with 
matters of consequence. Treaties are governed internationally 
by international law. The Vienna Convention on the Law of 
Treaties, which the United States has signed but not ratified, 
is the most widely recognized international law source on 
current treaty law practice.
     Non-binding international understandings do not show an 
intent to create legal relationships. Frequently, such 
understandings convey only an intent to perform an act or a 
commitment of a purely personal, political, or moral nature. 
They may be important, however, as they are often used and 
often evoke expectations of compliance from affected states.

                              ----------                              

    The purpose of this chapter is to identify the sources of 
constitutional authority underlying the conclusion of 
international agreements and the status of such agreements in 
the domestic law of the United States. To facilitate an 
understanding of the constitutional principles that are 
relevant to this area of the law, the succeeding discussion 
treats separately international agreements that are concluded 
in the form of ``treaties'' and those that are made in non-
treaty form by ``executive agreements.'' The distinction 
between these two modes of agreement-making is, of course, 
``purely a constitutional one and has no international 
significance.'' \2\ Even for purposes of domestic law, 
differentiation between treaties and executive agreements, at 
least on the basis of the nature or importance of the subject 
matter encompassed by these instruments, seems problematic in 
view of the actual practice of the nation under the 
Constitution. On the other hand, these two modes may be 
distinguished procedurally in that treaties, unlike executive 
agreements, are concluded exclusively pursuant to the joint 
action of the President and two-thirds of the Senate. Moreover, 
the domestic legal effect of treaties and executive agreements 
as law of the land may be identical in all circumstances.

                              A. Treaties

                        scope of the treaty power

     In providing that the President ``shall have Power, by and 
with the Advice and Consent of the Senate, to make Treaties, 
provided two-thirds of the Senators present concur,'' the 
treaty clause of the Constitution (Article II, Section 2, 
Clause 2) furnishes little textual guidance concerning the 
proper extent of the power so granted. Perhaps the most 
familiar judicial statement regarding the scope of this clause 
is that opined by the Supreme Court in Geofroy v. Riggs:
          * * * The treaty power, as expressed in the 
        Constitution, is in terms unlimited except by those 
        restraints which are found in that instrument against 
        the action of the government or of its departments, and 
        those arising from the nature of the government itself 
        and of the States. It would not be contended that it 
        extends so far as to authorize what the Constitution 
        forbids, or a change in the character of the government 
        or in that of one of the States, or a cession of any 
        portion of the territory of the latter, without its 
        consent * * * But with these exceptions, it is not 
        perceived that there is any limit to the questions 
        which can be adjusted touching any matter which is 
        properly the subject of negotiation with a foreign 
        country.\3\

used Senate treaty condition regarding constitutional supremacy, see 
``Condition Regarding Supremacy of the Constitution'' in Chapter V, 
Section C, infra.

    It seems clear from the Court's pronouncement in Geofroy v. 
Riggs that the treaty power is indeed a broad one, extending to 
``any matter which is properly the subject of negotiation with 
a foreign country.'' However, it is equally apparent that 
treaties, like Federal statutes, are subject to the overriding 
requirements of the Constitution. Although the Supreme Court 
has apparently never expressly held a treaty to be 
unconstitutional, the validity of the general principle has 
been repeated often and most unequivocally by the court in Reid 
v. Covert where Justice Black declared that ``[n]o agreement 
with a foreign nation can confer power on the Congress, or on 
any other branch of Government, which is free from the 
restraints of the Constitution.'' \4\

Wong Kim Ark, 169 U.S. 649, 700 (1898).
---------------------------------------------------------------------------
    While there is little difficulty in light of the case law 
in establishing the theoretical supremacy of the Constitution 
over treaties,\5\ the identification of specific constitutional 
limitations that may affect the treaty power is attended by 
some complexity. Various limitations have been suggested over 
the years and are reviewed in the following discussion.
---------------------------------------------------------------------------
    \5\ With the exception of Justice Holmes' dictum in Missouri v. 
Holland, 252 U.S. 416 (1920), there appears to have been little legal 
basis for questioning the validity of the general principle that 
treaties are subordinate to the Constitution. In Missouri v. Holland, 
Justice Holmes stated that-- * * * Acts of Congress are the supreme law 
of the land only when made in pursuance of the Constitution, while 
treaties are declared to be so when made under the authority of the 
United States [Art. VI, cl. 2]. It is open to question whether the 
authority of the United States means more than the formal acts 
prescribed to make the convention. 252 U.S. at 433.
    Any intimations from Justice Holmes' language that treaties might 
not be subject to constitutional requirements were, however, 
subsequently laid to rest in Reid v. Covert, 354 at 16-18, where 
Justice Black, in expressly refusing to read Missouri v. Holland as 
support for such a proposition, indicated that ``[n]o agreement with a 
foreign national can confer power on the Congress, or on any other 
branch of Government, which is free from the restraints of the 
Constitution.''
---------------------------------------------------------------------------
    It was asserted early by Jefferson in his Manual of 
Parliamentary Practice that the treaty power does not extend to 
``the rights reserved to the States; for surely the President 
and Senate can not do by treaty what the whole Government 
interdicted from doing in any way.'' \6\ Notwithstanding 
Jefferson's view, it seems well-settled since Missouri v. 
Holland \7\ that the powers reserved to the States under the 
10th amendment constitute no bar to the exercise of the treaty 
power. In Missouri v. Holland the Supreme Court sustained a 
treaty and implementing legislation concerning the protection 
of migratory birds, a subject that previously had been held 
within the reserved powers of the States and beyond the 
legislative competence of Congress. According to Justice 
Holmes:

          The treaty in question does not contravene any 
        prohibitory words to be found in the Constitution. The 
        only question is whether it is forbidden by some 
        invisible radiation from the general terms of the Tenth 
        Amendment.

                                 * * *

        Here a national interest of very nearly the first 
        magnitude is involved. It can be protected only by 
        national action in concert with that of another power. 
        The subject matter is only transitorily within the 
        State and has no permanent habitat therein. But for the 
        treaty and the statute there soon might be no birds for 
        any powers to deal with. We see nothing in the 
        Constitution that compels the Government to sit by 
        while a food supply is cut off and the protectors of 
        our forests and our crops are destroyed.\8\

    Although the unspecified reserved powers of the States 
under the 10th amendment seem inoperative as a limitation upon 
the treaty power, there may be rights conferred upon the States 
by other provisions of the Constitution that, at least in 
theory, could restrict treatymaking. It has been suggested that 
a treaty could not undermine the guaranty of the States to a 
``Republican Form of Government'' (Article IV, Section 4), or 
infringe the authority of a State concerning its militia 
(Article 1, Section 8, Clause 16, and Amendment 2) as in a 
treaty mandating abolition of State militias pursuant to a 
scheme of general disarmament.\9\ While the Court in Geofroy v. 
Riggs further indicated that a treaty may not cede a portion of 
the territory of a State without the latter's consent, such a 
restriction upon the treaty power is not specifically mentioned 
in the Constitution and the validity of this alleged limitation 
seems questionable.\10\

U.S. Army Corps of Engineers, No. 99-1178 (U.S. Jan. 9, 2001) have 
raised questions as to whether the treaty power may be similarly 
vulnerable to limitations grounded in federalism. Agreements that have 
been suggested as possibly raising such concerns are ``a disarmament 
agreement with inspection provisions that permits intrusion upon the 
statehouse, or a treaty that commands state legislatures to adopt laws 
or that coopts state officials.'' Henkin 1996, p. 194. For discussion

    A second major limitation upon treatymaking urged by 
Jefferson pertains to ``those subjects of legislation in which 
[the Constitution] gave a participation to the House [of 
Representatives].'' \11\ Concerning this limitation, Jefferson 
added that ``[t]his * * * exception is denied by some on the 
ground that it would leave very little matter for the treaty 
power to work on. The less the better, say others.'' \12\ 
Although there is judicial dicta that perhaps indirectly 
suggest such a restriction,\13\ Jefferson's assertion seems to 
have been refuted by the actual practice under the 
Constitution. Thus, instances are readily found of treaties 
containing subject matter that lies within Congress' delegated 
powers, as in treaties pertaining to foreign commerce, the 
payment of money, war, the organization of judicial tribunals, 
and rules of maritime blockage and capture.\14\ Moreover, it 
recently has been held that Congress' power to dispose of 
property belonging to the United States (Article IV, Section 3, 
Clause 2) presents no constitutional bar to disposition by 
treaty of American property interests in the Panama Canal.\15\

    While there appears to be general agreement that subject 
matter falling within the scope of Congress' delegated powers 
may be dealt with by treaty,\16\ a separate question, which is 
considered infra, concerns the extent to which a treaty 
touching such subjects can become effective as domestic law 
without the aid of an implementing statute. The distinction 
between these two issues is noted in the following commentary 
which, with reference to the argument that the treaty power is 
limited by Congress' delegated authority, states that:
---------------------------------------------------------------------------
    \16\ See Wright, Treaties and Separation of Powers, pp. 65-85;

---------------------------------------------------------------------------
          [I]t is not clear what the limitation means. If it is 
        meant that no international agreement could be 
        constitutionally entered into by the United States 
        within the sphere of such powers the practice from the 
        beginning has been to the contrary; if it is meant that 
        treaty provisions dealing with matters delegated to 
        Congress must, in order to become the law of the land, 
        receive the assent of Congress through implementing 
        legislation, it states not a limitation on the power of 
        making treaties as international conventions but rather 
        a necessary procedure before certain conventions are 
        cognizable by the courts in the enforcement of rights 
        under them.\17\

Interpretation, S. Doc. 6, 103d Cong., 1st Sess. 1996, pp. 485-486 
(hereafter cited as Constitution--Analysis and Interpretation).

    A third limitation upon the treaty power has been raised in 
connection with treaties authorizing participation by the 
United States in proceedings before certain types of 
international judicial tribunals. The basic constitutional 
issue concerning such participation seems whether the 
authorizing treaty improperly delegates the ``Judicial Power of 
the United States'' which the Constitution otherwise vests in 
``one Supreme Court, and in such inferior Courts as the 
Congress may from time to time ordain and establish'' (Article 
III, Section 1). It has been argued that where an international 
judicial tribunal adjudicates claims between nation-states, the 
type of judicial power being exercised is international, and, 
hence, there is no improper usurpation by treaty of the 
domestic ``Judicial Power of the United States'' for 
constitutional purposes.\18\ The International Court of Justice 
would be an example of this type of international tribunal.
---------------------------------------------------------------------------
    \18\ Henkin 1996, p. 267.
---------------------------------------------------------------------------
    On the other hand, a more serious constitutional objection 
might be raised against a treaty authorizing an international 
tribunal to exercise appellate jurisdiction over cases from 
U.S. courts. An arrangement of this nature was envisioned in 
The Hague Prize Court Convention of 1907 \19\ which established 
an international court with appellate jurisdiction from 
national courts in prize cases. Concerned that this procedure 
would be inconsistent with the final appellate jurisdiction of 
the Supreme Court, American negotiators proposed a 
supplementary protocol \20\ authorizing de novo actions against 
the United States before the International Prize Court in lieu 
of appeals from domestic courts.\21\

---------------------------------------------------------------------------
    A fourth limitation which has been alleged to circumscribe 
the treaty power is that treaties must relate to ``proper 
subjects of negotiation'' with a foreign nation. Such a 
limitation is suggested by judicial dicta \22\ and may also be 
present in Jefferson's statement that ``[b]y the general power 
to make treaties, the Constitution must have intended to 
comprehend only those subjects which are usually regulated by 
treaty * * *.'' \23\ This restriction is also associated with 
remarks made by Charles Evans Hughes before the annual meeting 
of the American Society of International Law in 1929 where he 
asserted that ``[t]he power [of treaty-making], is to deal with 
foreign nations with regard to matters of international 
concern. It is not a power intended to be exercised, it may be 
assumed, with respect to matters that have no relation to 
international concerns.'' \24\ While the ``international 
concern'' limitation upon treatymaking had been generally 
accepted,\25\ the American Law Institute rejected this view in 
1987 in its Restatement (Third) of the Foreign Relations Law of 
the United States.\26\ There has been no clear test for 
determining the circumstances in which the doctrine should 
apply and it has been observed, moreover, that ``[m]atters of 
international concern are not confined to matters exclusively 
concerned with foreign relations. Usually, matters of 
international concern have both international and domestic 
effects, and the existence of the latter does not remove a 
matter from international concern.'' \27\ The limitation 
appears to have rarely been an issue in reported decisions. In 
Power Authority of New York v. Federal Power Commission,\28\ a 
Federal Circuit Court of Appeals, in order to avoid declaring 
an entire treaty void for want of international concern, 
invoked the restriction against a ``reservation'' which the 
Senate had attached to the treaty but which the court viewed as 
merely an expression of the ``Senate's desires'' and of 
``domestic policy.'' \29\
---------------------------------------------------------------------------
    \22\ In Holden v. Joy, 17 Wall. (84 U.S.) at 243, the Court stated 
that the treaty power ``should extend to all those objects which in the 
intercourse of nations had usually been regarded as the proper subjects 
of negotiation and treaty.'' See also Geofroy v. Riggs, 133 U.S. at 
267, quoted in the text accompanying note 3 supra, and Akasura v. 
Seattle, 265 U.S. 332, 341 (treaty power ``extend[s] to all proper 
subjects of negotiation between out government and other nations'').

Relations Law of the United States (1965), Sec. 117, Comment b. In this 
regard, the current Foreign Relations Restatement observes--There is no 
principle either in international law or in U.S. constitutional law 
that some subjects are intrinsically ``domestic'' and hence 
impermissible subjects for an international agreement. As to 
international law, it has been authoritatively stated that even a 
subject that is strictly of domestic concern ``ceases to be one solely 
within the domestic jurisdiction of the State [and] enters the domain 
governed by international law,'' if states conclude an international 
agreement about it. Nationality Decrees in Tunis and Morocco (Great 
Britain v. France), P.C.I.J. ser. B, No. 4, p. 26 (1923). Under U.S. 
laws, the Supreme Court has upheld agreements on matters that, apart 
from the agreement, were strictly domestic and indeed assumed to be 
within state rather than Federal authority. For example, De Geofroy v. 
Riggs [133 U.S. 258] * * * (rights of inheritance in land); Missouri v. 
Holland [252 U.S. 416] * * * (protection of migratory birds). Early

concern were later abandoned. * * *'' Rest. 3d, Sec. 302, Reporters'

    \29\ The reservation at issue, which had been attached by the 
Senate to the Treaty Concerning Uses of the Waters of the Niagara 
River, Feb. 27, 1950, United States-Canada, 1 U.S.T. 694, specified 
that the United States reserved the right to develop its share of the 
Niagara River by an act of Congress and that redevelopment projects in 
such waters were prohibited until authorized by congressional 
enactment. The decision has been criticized for its failure to 
recognize the existence of genuine international concern regarding the 
Senate's reservation. See Henkin, Louis, The Treaty Makers and the Law 
Makers: The Niagara Reservation. Columbia Law Review, v. 56, 1956, p. 
1151. See also text at notes 36-38 infra. In United States v. Lue, 134 
F. 3d 79 (2d Cir. 1998), the Federal Circuit Court of Appeals rejected 
appellant's argument that the International Convention Against the 
Taking of Hostages was beyond the power of the Executive to sign under 
Article II because it regulated matters of domestic concern not 
involving relations with other nations. The court took note of the 
breadth of the treaty power, though admitting a possible constitutional 
``outer limit.'' It concluded that the convention did not in any event 
``transgress'' any such limit, as it addressed two issues of central 
international concern: the treatment of foreign nationals while they 
are on local soil and hostage taking as a vehicle for terrorism. 134 F. 
3d at 83.
---------------------------------------------------------------------------
    A fifth and widely recognized limitation upon the treaty 
power is that provided by the Bill of Rights.\30\ This 
restriction upon treatymaking seems implicit from the context 
of Justice Black's reminder in Reid v. Covert that ``[n]o 
agreement with a foreign national can confer power on the 
Congress, or on any other branch of Government, which is free 
from the restraints of the Constitution,'' and that ``[t]he 
prohibitions of the Constitution were designed to apply to all 
branches of the National government, and they cannot be 
nullified by the Executive or by the Executive and the Senate 
combined.'' \31\ The necessity for Justice Black's statement 
originated in the contention, which the court rejected, that 
Article 2(11) of the Uniform Code of Military Justice,\32\ 
which effectively denied trial by jury and other Bill of Rights 
protections to civilian dependents accompanying American armed 
forces abroad, could nevertheless be sustained as legislation 
necessary and proper to implement U.S. jurisdictional rights 
under specified bilateral agreements with foreign host 
governments.

    Whatever specific constitutional limitations may be deemed 
applicable to the treaty power in a given case, the courts, in 
lieu of express declarations of unconstitutionality, evidence a 
proclivity merely to refuse full effectuation of specific 
treaty provisions that might offend constitutional 
requirements. Thus, in City of New Orleans v. United 
States,\33\ a treaty provision conferring ``full sovereignty'' 
upon the United States over ceded public lands was held 
ineffective by the Supreme Court to prohibit the sale of the 
land by city authorities where recognition of Federal title 
under the treaty would have deprived just compensation to 
vested private property interests in derogation of the fifth 
amendment. An additional example is afforded by Rocca v. 
Thompson,\34\ where the Court, after noting ``there is, of 
course no Federal law of probate or the administration of 
estates,'' refused to preempt the local administration of an 
alien decedent's estate notwithstanding a treaty provision 
which permitted resident foreign consuls to ``intervene'' in 
estate liquidation proceedings of foreign nationals dying 
intestate in the United States. In a similar vein is United 
States ex rel. Martinez Angusto v. Mason,\35\ where a Federal 
Circuit Court of Appeals, in the absence of an authorizing 
statute or Presidential directive, refused to deem Navy and 
Immigration and Naturalization Service agents as ``competent 
national or local authorities'' under an applicable treaty for 
purposes of sanctioning the warrantless arrest and subsequent 
imprisonment of a deserting Spanish seaman. In Colello v. U.S. 
Securities and Exchange Commission, however, a case challenging 
a freeze of plaintiffs' assets in Switzerland, a Federal 
District Court held that the failure of the U.S.-Switzerland 
Treaty on Mutual Assistance in Criminal Matters to require U.S. 
officials to notify U.S. citizens of a governmental request for 
assistance from Switzerland and to provide a prompt post-
deprivation hearing violated their fifth amendment right to due 
process and to this extent the treaty was unconstitutional.\36\ 
It further held that the treaty's ``reasonable suspicion'' 
standard for freezing U.S. citizens' assets in Switzerland 
violated the fourth amendment, stating that ``[t]he executive 
cannot eliminate plaintiffs' fourth amendment right to be free 
of unreasonable searches by treaty.'' \37\

    Questions regarding fourth and fifth amendment protections for U.S. 
firms arose during Senate consideration of the Convention on the 
Prohibition of the Development, Production, Stockpiling and Use of 
Chemical Weapons. Done at Paris, January 13, 1993, entered into force 
April 29, 1997, International Legal Materials, v. 32, 1993, p. 800. The 
convention was approved by the Senate April 24, 1997. Congressional 
Record, April 24, 1997, p. S3651 (daily ed.). Fourth amendment 
protections against unreasonable search and seizure were implicated by 
treaty obligations regarding routine and challenge inspections of 
chemical facilities in party countries. Fifth amendment protections 
against governmental takings were implicated by the inspections 
themselves, since they could possibly result in property loss, 
particularly that of confidential business information. See U.S. 
Congress. Senate. Committee on the Judiciary. Constitutional 
Implications of the Chemical Weapons Convention. S. Hrg. 104-859, Sept. 
10, 1996; U.S. Congress. Senate. Committee on Foreign Relations. 
Chemical Weapons Convention. S. Hrg. 105-183, April 8-17, 1997.
    The Senate's advice and consent was made subject to numerous 
conditions, including (1) a direction to the President to withhold a 
portion of the U.S. contribution to the Organization of the Prohibition 
of Chemical Weapons created under the convention in the event certain 
disclosures of U.S. business information occurred or there were certain 
breaches of confidentiality, and (2) a requirement that the President, 
before depositing the U.S. instruments of ratification, certify to the 
Congress that in the event a firm withholds its consent to a search, 
the United States will first obtain a criminal search warrant supported 
by probable cause for challenge inspections and administrative warrant 
from a U.S. magistrate judge for routine inspections. Congressional 
Record, April 27, 1997, pp. S3655, S3657. Implementing legislation set 
forth further domestic legal requirements involving convention 
activities by, among other things, providing for civil actions against 
the United States for claims for taking of property and setting forth 
warrant requirements for routine and challenge inspections. Chemical

    Judicial concern for constitutional requirements is also 
evident in Power Authority of New York v. Federal Power 
Commission, supra, where, as previously noted, the court 
declined to view a Senate ``reservation'' as part of the treaty 
to which it was attached, preferring instead to view the 
reservation as merely an expression of ``the Senate's desires'' 
and of ``domestic policy.'' \38\ The Senate's reservation, 
which was appended to a bilateral treaty with Canada allocating 
the waters of the Niagara River for power development, 
specified that the United States reserved the right to 
redevelop its share of the river waters by an act of Congress 
and that redevelopment projects in such waters were prohibited 
until authorized by congressional enactment. In characterizing 
the reservation as purely domestic and hence not part of the 
treaty, the Circuit Court avoided possible holdings that the 
entire treaty was void for want of ``international concern'' 
and that the Senate was unconstitutionally ``legislating'' 
through ``reservation'' without the concurrence of the House of 
Representatives inasmuch as the reservation would have 
temporarily suspended the operation of existing law.\39\

(Article VI, Clause 2), a treaty which is concluded compatibly 
with applicable constitutional requirements of the type 
previously discussed may have status as the ``Supreme Law of 
the Land'' along with Federal statutes and the Constitution 
itself. However, a treaty's effectiveness as domestic law of 
the United States does not result automatically upon its entry 
into force on the international level, but occurs only where 
the instrument is ``self-executing,'' that is, where it 
operates without any necessity for implementing legislation. 
The classic exposition of this principle is provided by Chief 
Justice Marshall in Foster v. Neilson:
          * * * Our constitution declares a treaty to be the 
        law of the land. It is, consequently, to be regarded in 
        courts of justice as equivalent to an act of the 
        legislature, whenever it operates of itself, without 
        the aid of any legislative provision. But when the 
        terms of the stipulation import a contract, when either 
        of the parties engages to perform a particular act, the 
        treaty addresses itself to the political, not the 
        judicial department; and the legislature must execute 
        the contract, before it can become a rule for the 
        Court.\40\

    Application of this general rule seems relatively simple 
where the text of a treaty expressly recognizes the necessity 
for implementing legislation or where the subject matter of the 
treaty falls within an area traditionally regarded as requiring 
congressional effectuation by statute. Concerning the latter 
situation there appears to be general agreement that in view of 
Congress' exclusive power of appropriations (Article 1, Section 
9, Clause 7) a treaty provision authorizing the payment of 
money is not self-executing.\41\ Similarly, an implementing 
statute also seems required in connection with treaties which 
specify international crimes or criminal sanctions for 
particular activities.\42\ In this connection, it has been 
noted that ``[c]riminal law to implement the foreign relations 
of the United States is wholly statutory.'' \43\ Moreover, in 
light of Congress' power under Article I, Section 8, Clause 11, 
``to declare War,'' it seems to be generally assumed that a 
treaty would not be sufficient of itself to place the United 
States in a state of war.\44\ Concerning the general rule that 
treaties which pertain to the aforementioned matters require 
congressional implementation, it has been observed that:

House of Representatives early asserted its prerogatives by reserving a 
right of independent judgment regarding monies required to be paid 
under the Jay Treaty of 1796. Jefferson's Manual, p. 297; 
Constitution--Analysis and Interpretation, p. 480. In Turner v. 
American Baptist Missionary Union, 24 F. Cas. 344 (No. 14,251) 347 
(C.C. Mich. 1852), the Circuit court stated: A treaty under the Federal 
Constitution is declared to be the supreme law of the land. This, 
unquestionably, applies to all treaties, where the treatymaking power, 
without the aid of Congress, can carry it into effect. It is not, 
however, and cannot be the supreme law of the land, where the 
concurrence of Congress is necessary to give it effect. Until this 
power is exercised, as where the appropriation of money is required, 
the treaty is not perfect. It is not operative, in the sense of the 
Constitution, as money cannot be appropriated by the treatymaking 
power. This results from the limitations of our government. The action 
of no department of the government, can be regarded as law, until it 
shall have all the sanctions required by the Constitution to make it 
such. As well might be contended, that an ordinary act of Congress, 
without the signature of the President, was a law, as that a treaty 
which engages to pay a sum of money is in itself law. And in such a 
case, the representatives of the people and the States, exercise their 
own judgments in granting or withholding the money. They act upon their 
own responsibility, and not upon the responsibility of the treatymaking 
power.

Over the Top, 5 F. 2d 838, 845 (D. Conn. 1925), a district court stated 
that-- * * * It is not the function of treaties to enact the fiscal or 
criminal law of a nation. For this purpose no treaty is self-executing. 
Congress may be under a duty to enact that which has been agreed upon 
treaty, but duty and its performance are two separate and distinct 
things. Nor is there any doubt that the treatymaking power has its 
limitations. What these are has never been defined, perhaps never need 
be defined. Certain it is that no part of the criminal law of this 
country has ever been enacted by treaty.

          * * * There is no definitive authority for the rule * 
        * * that agreements on some subjects cannot be self-
        executing. That a subject is within the legislative 
        power of Congress does not preclude a treaty on the 
        same subject. * * * No particular clause of the 
        Constitution conferring power on Congress states or 
        clearly implies that the power can be exercised only by 
        Congress, not by the treaty-makers. (Contrast the 
        provision that Congress shall have the power to 
        `exercise exclusive legislation in all Cases 
        whatsoever' over the District of Columbia and other 
        places acquired for `needful buildings.' U.S. 
        Constitution, Article 1, Section 8, clause 17.) * * * 
        The power of Congress to declare war is not 
        characterized or designated in any way that would 
        distinguish it from, say, the power to regulate 
        commerce with foreign nations, yet regulation of such 
        commerce is surely a proper subject for a treaty. The 
        provision that ``No money shall be drawn from the 
        Treasury, but in Consequence of Appropriations made by 
        Law'' lends itself better to the suggestion that an 
        international agreement cannot itself ``appropriate 
        money.'' Even here, it might have been possible to 
        conclude that since treaties are declared to be ``law'' 
        (Art. VI) and are treated as equal to an act of 
        Congress for other purposes, an appropriation of funds 
        through an international agreement is an appropriation 
        ``made by law.''
          * * * The principle declared * * * is nevertheless 
        generally assumed for the cases given.\45\

    \45\ Rest. 3d, Sec. 111, Reporters' Note 6.

    Apart from instances where the terms of a treaty expressly 
contemplate implementing legislation or where such legislation 
is traditionally required owing to the nature of a particular 
treaty provision, whether a treaty is self-executing or not is 
a matter of interpretation, initially for the Executive and 
ultimately for the courts in the event of litigation.\46\ 
Decisional criteria for resolving this issue have been 
variously and broadly phrased. Thus, it has been stated that 
``[i]n determining whether a treaty is self-executing courts 
look to the intent of the signatory parties as manifested by 
the language of the instrument, and, if the instrument is 
uncertain, recourse must be had to the circumstances 
surrounding its execution.'' \47\ Elsewhere it is maintained 
that where the self-executing nature of an international 
agreement is unclear, ``account must be taken of any statement 
by the President in concluding the agreement or in submitting 
it to the Senate for consent * * * and of any expression by the 
Senate * * * in dealing with the agreement.'' \48\ 
Alternatively, it is urged that reference should be made to 
``the purposes of the treaty and the objectives of its 
creators, the existence of domestic procedures and institutions 
appropriate for direct implementation, the availability and 
feasibility of alternate enforcement methods, and the immediate 
and long-range social consequences of self- or non-self-
execution.'' \49\

of International Law, v. 14, 1970, pp. 312-313. Henkin notes that 
sometimes ``federal legislation adopted prior to the treaty (ane even 
for other purposes) may be available to implement a treaty obligation; 
sometimes the President may have authority to carry out those 
obligations without Congressional authorization. State law may also 
serve to implement non-self-executing obligations.'' Henkin 1996, p. 
200.
    The Senate included an express declaration in the resolutions of 
ratification for various human rights treaties stating that the treaty 
is not self-executing; the declaration was later included in the U.S. 
instrument of ratification for the treaty. See Congressional Record, v.

Frolova v. Union of Soviet Socialist Republics, 761 F. 2d 370, 373 (7th

consider in discerning the intent of the treaty parties as to whether a 
treaty is self-executing: ``(1) the language and purposes of the 
agreement as a whole; (2) the circumstances surrounding its execution; 
(3) the nature of the obligations imposed by the agreement; (4) the 
availability and feasibility of alternative enforcement mechanisms; (5) 
the implications of permitting a private right of action; and (6) the 
capability of the judiciary to resolve the dispute.''
---------------------------------------------------------------------------
    Where a treaty is deemed to be self-executing, any 
conflicting provisions of State law must yield. This principle, 
which is expressly enshrined in the supremacy clause of the 
Constitution, was early affirmed by the Supreme Court in Ware 
v. Hylton.\50\ According to Justice Chase:
---------------------------------------------------------------------------
    \50\ 3 Dall. (3 U.S.) 199 (1796).
---------------------------------------------------------------------------
          A treaty cannot be the supreme law of the land, that 
        is, of all the United States, if any act of a State 
        Legislature can stand in its way. If the Constitution 
        of a State * * * must give way to a treaty, and fall 
        before it; can it be questioned, whether the less 
        power, an act of the State Legislature, must not be 
        prostrate? It is the declared will of the people of the 
        United States, that every treaty made by the authority 
        of the United States, shall be superior to the 
        Constitution and laws of any individual State; and 
        their will alone is to decide. If a law of a State, 
        contrary to a treaty, is not void, but voidable only, 
        by a repeal, or nullification by a State Legislature, 
        this certain consequence follows, that the will of a 
        small part of the United States may control or defeat 
        the will of the whole.\51\
---------------------------------------------------------------------------
    \51\ Ibid. at 236-237. The principle has been reaffirmed by the 
Court in numerous cases. For additional case authority, see 
Constitution--Analysis and Interpretation, pp. 472-474.

    In the event of a conflict between a self-executing treaty 
and a Federal statute, it is well-settled that legal primacy 
will be accorded the measure which is later in time, albeit the 
courts will endeavor to harmonize the respective international 
and domestic obligations if possible. As indicated by the 
Supreme Court in Whitney v. Robertson:
          By the Constitution a treaty is placed on the same 
        footing, and made of like obligation, with an act of 
        legislation. Both are declared by that instrument to be 
        the supreme law of the land, and no superior efficacy 
        is given to either over the other. When the two relate 
        to the same subject, the courts will always endeavor to 
        construe them so as to give effect to both, if that can 
        be done without violating the language of either; but 
        if the two are inconsistent, the one last in date will 
        control the other, provided always the stipulation of 
        the treaty on the subject is self-executing. If the 
        country with which the treaty is made is dissatisfied 
        with the action of the legislative department, it may 
        present its complaint to the executive head of the 
        government and take such other measures as it may deem 
        essential for the protection of its interests. The 
        courts can afford no redress. Whether the complaining 
        nation has just cause or our country was justified in 
        its legislation, are not matters for judicial 
        cognizance.\52\
---------------------------------------------------------------------------
    \52\ 124 U.S. 581, 594 (1888). The Court has repeated the rule in 
many cases. See discussion in Constitution--Analysis and 
Interpretation, pp. 478-479, and Breard v. Greene, 523 U.S. 371, 376-77 
(1998).

    If a particular treaty is not self-executing, and, 
accordingly, requires legislative implementation to become law 
of the land, Congress may enact such legislation 
notwithstanding that the subject matter of the treaty would 
normally be beyond congressional competence. This result arises 
by virtue of the necessary and proper clause of the 
Constitution (Article I, Section 8, Clause 18) which authorizes 
Congress to make all laws necessary and proper to effectuate 
not only its expressly delegated powers, but also ``all other 
Powers vested by this Constitution in the government of the 
United States or in any Department or Officer thereof.'' 
Application of this principle seems most evident in Missouri v. 
Holland \53\ where Justice Holmes sustained both a treaty and 
an implementing act even though comparable legislation, when 
unaided by a treaty, had previously been declared invalid by 
the courts. Concerning this bootstrapping effect on the treaty 
power it has been observed that:

(1901), indicating that the necessary and proper clause of the 
Constitution is sufficient authority for Congress ``to enact such 
legislation as is appropriate to give efficacy to any stipulations 
which it is competent for the President by and with the advice and 
consent of the Senate to insert in a treaty with a foreign power.'' See 
generally Constitution--Analysis and Interpretation, pp. 480-482; Rest. 
3d, Sec. 111, Comment j.
---------------------------------------------------------------------------
          * * * [T]he treaty power cannot purport to amend the 
        Constitution by adding to the list of Congress' 
        enumerated powers, but having acted, the consequence 
        will often be that it has provided Congress with an 
        opportunity to enact measures which independently of a 
        treaty Congress could not pass; the only question that 
        can be raised as to such measures will be whether they 
        are necessary and proper measures for carrying of the 
        treaty in question into operation.\54\
---------------------------------------------------------------------------
    \54\ Constitution--Analysis and Interpretation, pp. 481-482.

    To the foregoing, it may be added that where a treaty 
requires implementing legislation for its effectuation, 
strictly speaking it is the statute and not the treaty which is 
the law of the land for the courts.\55\ A caveat to this 
proposition exists, however, when the treaty itself is 
incorporated as part of the statute.\56\

States. That is true even when a non-self-executing agreement is 
`enacted' by, or incorporated in, implementing legislation.''
---------------------------------------------------------------------------

                      B. Executive Agreements \57\
---------------------------------------------------------------------------

    \57\ Executive agreements are also discussed in Chapters II, III, 
IX, and X.
---------------------------------------------------------------------------
    Reference to the text of the Constitution suggests the 
preeminent legal status of the treaty mode of agreement-making. 
Treaties, for example, are made only by the President and two-
thirds of the Senate (Article II, Section 2, Clause 2), form 
part of the ``Supreme Law of the Land'' (Article VI, Clause 2), 
and create a basis for invoking the jurisdiction of the Federal 
courts (Article III, Section 2, Clause 1). Moreover, the States 
are absolutely prohibited from entering into any treaty 
(Article I, Section 10, Clause 1). While the Constitution thus 
expressly references the treaty mode four times, only once does 
the text of the Nation's fundamental law appear to recognize 
the existence of other types of international instruments, as 
in the prohibition against the States from concluding any 
``Agreement or Compact'' with a foreign power in the absence of 
congressional approbation (Article I Section 10, Clause 3).
    On the other hand, the actual practice of the Nation under 
the Constitution confirms a numerical primacy of agreements 
which have not been concluded in the form of treaties.\58\ Such 
agreements are typically denominated as ``executive 
agreements'' and may be further categorized as follows: (1) 
congressional-executive agreements sanctioned by the joint 
authority of the President and both Houses of Congress; (2) 
agreements concluded pursuant to existing treaties; and (3) 
Presidential or ``sole'' executive agreements made by the 
President on his independent constitutional authority.
---------------------------------------------------------------------------
    \58\ The editors of the Constitution--Analysis and Interpretation, 
pp. 494-495, observe that-Once a stepchild in the family in which 
treaties were the preferred offspring, the executive agreement has 
surpassed in number and perhaps in international influence the treaty 
formally signed, submitted for ratification to the Senate, and 
proclaimed upon ratification.
    During the first half-century of its independence, the United 
States was party to 60 treaties but to only 27 published executive 
agreements. By the beginning of World War II, there had been concluded 
approximately 800 treaties and 1,200 executive agreements * * *. In the 
period since 1939, executive agreements have comprised more than 90 
percent of the international agreements concluded.
---------------------------------------------------------------------------
    In view of the numerical superiority of executive 
agreements in actual practice as contrasted with the textual 
primacy accorded the treaty mode by the Constitution, and owing 
as well to the controversial nature of particular executive 
agreements, it is perhaps not surprising that questions have 
been raised concerning the exclusive scope vel non of the 
treaty clause and the possible existence of a substantive 
distinction between treaties and executive agreements. 
Notwithstanding substantial scholarship devoted to ascertain 
the Framers' intentions concerning these matters, the 
understanding of the Drafters remains largely obscure.\59\ By 
virtue of actual practice and judicial edification, however, it 
is now well-settled that the treaty mode is not an exclusive 
means of agreement-making for the United States and that 
executive agreements may validly co-exist with treaties under 
the Constitution. Somewhat less clear, it seems, is whether any 
subject that is dealt with by treaty may also be effected by an 
executive agreement, particularly by an agreement concluded by 
the President on his sole constitutional authority.\60\ The 
succeeding discussion further develops these points by 
presenting a review of the practice and case law associated 
with each of the three types of executive agreements.

                   congressional-executive agreements

     Congressional authorization for the conclusion of 
international agreements dates from the earliest days of the 
Nation's constitutional history. Thus, in 1790 Congress 
empowered the President to pay off the Revolutionary War debt 
by borrowing money from foreign countries ``upon terms 
advantageous to the United States'' and to conclude ``such 
other contracts respecting the said debt as shall be found for 
the interest of the said States.'' \61\ Two years later the 
Postmaster General was authorized to ``make arrangements with 
the postmasters in any foreign country for the reciprocal 
receipt and delivery of letters and packets, through the post-
offices.'' \62\ The authority for the conclusion of postal 
agreements was continued in later enactments and formed the 
basis of numerous postal ``conventions'' which were never 
submitted to the Senate.\63\ Over the years, Congress has 
authorized or sanctioned additional agreements concerning a 
wide variety of subjects including, inter alia, the protection 
of intellectual property rights,\64\ acquisition of 
territory,\65\ national participation in various international 
organizations,\66\ foreign trade,\67\ foreign military 
assistance,\68\ foreign economic assistance,\69\ atomic energy 
cooperation,\70\ and international fishery rights.\71\

    The subject matter diversity of congressional-executive 
agreements is matched by the varying means by which Congress 
has authorized the conclusion of such agreements. Thus, 
Congress has enacted statutes providing authority in advance 
for the President to negotiate with other nations on a 
particular matter. This authority may be explicit,\72\ or, in 
the case of agreements concluded in conformity with a generally 
enunciated congressional policy, implied from the terms of the 
enactment.\73\ Legislative authorization for congressional-
executive agreements may also be effected by passage of a 
statute following the negotiation of a concluded agreement. 
Again, congressional approval may be explicit,\74\ or, implied, 
as in the case of legislation appropriating funds to carry out 
participation by the United States in an international 
organization.\75\

exporting [specified articles] imposes duties or other exactions upon

    In regulating the use of congressional-executive 
agreements, Congress has specified in advance the general terms 
of negotiation \76\ and conditioned the effectiveness of 
particular agreements alternatively upon the enactment of 
implementing legislation,\77\ upon the legislative adoption of 
an approving concurrent resolution within a specified time 
following transmittal of the agreement to Congress,\78\ or upon 
the failure of Congress to adopt a disapproving concurrent \79\ 
or joint \80\ resolution within designated time periods. 
Furthermore, congressional approval of some agreements has been 
accompanied by conditions.\81\ The President is presently 
required by at least one statute to select Members of Congress 
from specified committees to serve as accredited advisers to 
American delegations attending international conferences, 
meeting, and negotiating sessions relating to trade 
agreements.\82\ Other legislation has required the President to 
consult with specified committees before entering into trade 
agreements.\83\

of executive branch exercises of statutorily delegated authority. INS 
v. Chadha, 462 U.S. 919 (1983) and United States Senate and United 
States House of Representatives v. Federal Trade Commission, 463 U.S. 
1216 (1983). Accordingly, Congress in 1990 amended section 405(c) to

    The constitutionality of congressional-executive agreements 
appears to have been first raised before the Supreme Court in 
Field v. Clark.\84\ In Field it was alleged that section 3 of 
the Tariff Act of 1890,\85\ which authorized the President to 
suspend exemptions from import duties on specified articles 
unless reciprocity could be obtained with other nations, 
unconstitutionally delegated both the legislative and 
treatymaking power. Although no specific agreement was in 
issue, a number of reciprocal trade agreements had already been 
concluded pursuant to section 3.\86\ In meeting the objection 
that the Act unlawfully delegated Congress' legislative powers, 
the Court cited numerous statutory precedents dating from the 
early days of the Nation's constitutional history. The 
existence of these precedents permitted the Court summarily to 
dispose of the additional argument--that the treaty power had 
been unlawfully delegated--with the reply that ``[w]hat has 
been said [regarding the delegation of legislative authority] 
is equally applicable to the objection that the third section 
of the Act invests the President with treaty-making power * * * 
[T]he Court is of opinion that the third section of the Act of 
October 1, 1890, is not liable to the objection that it 
transfers legislative and treaty-making power to the 
President.'' \87\
---------------------------------------------------------------------------
    \84\ 143 U.S. 649 (1892). Although the issue was not squarely 
presented, the Supreme Court, in Texas v. White, 7 Wall. (74 U.S.) 700 
(1868), and in Hawaii v. Mankichi, 190 U.S. 197 (1903), seemed 
implicitly to approve the bypassing of the treaty mode in the 
acquisition of Texas and Hawaii by the United States.

    \86\ Crandall lists ten commercial agreements which were concluded 
under section 3 of the Tariff Act of 1890. See Crandall, p. 122. The 
decision in Field v. Clark, 143 U.S. 649 (1892), was rendered after six 
agreements had already become effective by proclamation.
    \87\ 143 U.S. at 694.
---------------------------------------------------------------------------
    Twenty years later, in B. Altman & Co. v. United 
States,\88\ the Court held that a reciprocal trade agreement 
between the United States and France,\89\ concluded pursuant to 
section 3 of the Tariff Act of 1897,\90\ was a ``treaty'' for 
purposes of section 5 of the Circuit Court of Appeals Act of 
1891 \91\ permitting direct appeals to the Supreme Court in any 
case involving the validity or construction of a ``treaty.'' 
Although the Court acknowledged that the trade agreement was 
not a treaty in the technical sense of Article II, Section 2, 
of the Constitution, it did not inquire into the 
constitutionality of the authorizing legislation, preferring 
simply to characterize the issue as one of ascertaining 
Congress' intent under the Circuit Court of Appeals Act. 
According to the Court:
---------------------------------------------------------------------------
    \88\ 224 U.S. 583 (1912).
    \89\ Commercial Agreement of May 30, 1898, United States-France, 30 
Stat. 1774.
    \90\ 30 Stat. 203.
    \91\ 26 Stat. 827-828.
---------------------------------------------------------------------------
          [The Circuit Court of Appeals Act] was intended to 
        cut down and limit the jurisdiction of this court and 
        many cases were made final in the Circuit Court of 
        Appeals which theretofore came to this court, but it 
        was thought best to preserve the right to a review by 
        direct appeal or writ of error from a Circuit Court in 
        certain matters of importance, and, among others, those 
        involving the construction of treaties. We think that 
        the purpose of Congress was manifestly to permit rights 
        and obligations of that character to be passed upon in 
        the Federal Court of final resort, and that matters of 
        such vital importance, arising out of opposing 
        constructions of international compacts, sometimes 
        involving the peace of nations, should be subject to 
        direct and prompt review by the highest court of the 
        Nation. While it may be true that this commercial 
        agreement, made under authority of the Tariff Act of 
        1897, Sec. 3, was not a treaty possessing the dignity 
        of one requiring ratification by the Senate of the 
        United States, it was an international compact, 
        negotiated between the representatives of two sovereign 
        nations made in the name and on behalf of the 
        contracting countries, and dealing with important 
        commercial relations between the two countries, and was 
        proclaimed by the President. If not technically a 
        treaty requiring ratification, nevertheless it was a 
        compact authorized by the Congress of the United 
        States, negotiated and proclaimed under the authority 
        of its President. We think such a compact is a treaty 
        under the Circuit Court of Appeals Act, and, where its 
        construction is directly involved, as it is here, there 
        is a right of review by direct appeal to this 
        court.\92\
---------------------------------------------------------------------------
    \92\ 224 U.S. at 601.

    Evidencing a similar lack of interpretative rigidity is 
Louis Wolf & Co. v. United States \93\ wherein the U.S. Court 
of Customs and Patent Appeals held that a United States-Cuba 
Trade Agreement of 1934,\94\ which had been effected under 
section 350(a) of the Tariff Act of 1930,\95\ was a 
``commercial convention'' within the meaning of treaties 
concluded by the United States with Norway \96\ and 
Austria.\97\ The latter two treaties exempted from 
unconditional most-favored-nation treatment goods accorded 
preferential treatment by the United States under a United 
States-Cuban Commercial Convention of 1902 or any other 
``commercial convention'' which might subsequently be concluded 
between the United States and Cuba. In holding that the 1934 
United States-Cuba Trade Agreement was a ``commercial 
convention'' within the meaning of the Austrian and Norwegian 
treaties, the court declared that:
---------------------------------------------------------------------------
    \93\ 107 F. 2d 819 (C.C.P.A. 1939)
    \94\ Agreement Respecting Reciprocal Trade, United States-Cuba, 
Aug. 24, 1934, 49 Stat. 3559.
    \95\ Sec. 350(a) of the Tariff Act of 1930, 46 Stat. 708, as added 
by the Reciprocal Trade Agreements Act of 1934, 48 Stat. 943.

States-Norway, June 5, 1928, 47 Stat. 2135.
    \97\ Treaty of Friendship, Commerce, and Consular Rights, United 
States-Austria, June 19, 1928, 47 Stat. 1876.
---------------------------------------------------------------------------
          * * * We think that by the use of the term 
        ``commercial convention'' such a trade agreement as the 
        Cuban Trade Agreement of 1934 was intended to be 
        included, and it is our opinion that that agreement is 
        a commercial convention although it was not ratified by 
        the Senate. It is true that the treaties with Norway 
        and Austria refer to the Cuban treaty of 1902 as a 
        ``Commercial Convention'' and that it was ratified by 
        the Senate. The treaty of 1902 refers to itself as a 
        ``convention.'' We think it well settled that the term 
        ``commercial convention'' is broad enough to include 
        commercial conventions which are ratified by the Senate 
        when negotiated by the executive department of the 
        Government, but that it also includes certain 
        commercial agreements which may be authorized by 
        Congress, if such conventions are within the powers so 
        delegated.
          On this phase of the case we think it proper to say 
        that the President, pursuant to acts of Congress, 
        frequently has entered into agreements with foreign 
        States.\98\

    \98\ 107 F. 2d at 826.

    While the issue concerning the constitutionality of 
congressional-executive agreements was either summarily 
resolved or substantially avoided in Field v. Clark, Altman, 
and Louis Wolf, a more detailed resolution of this question was 
evidenced by the U.S. Customs Court in Star-Kist Foods, Inc. v. 
United States.\99\ In Star-Kist, the court held that a trade 
agreement between the United States and Iceland,\100\ which was 
authorized by section 350(a) of the Tariff Act of 1930,\101\ 
was not an unconstitutional delegation of the treaty power. In 
determining that the Icelandic agreement was ``not a treaty 
requiring concurrence by the United States Senate within the 
meaning of the term, as used in the Constitution,'' the court 
relied heavily upon Field v. Clark, Altman, and Louis 
Wolf.\102\ Specifically noteworthy, however, is the concurring 
opinion of Judge Mollison which not only assessed the 
precedential significance of Field v. Clark, but also 
articulated a theoretical basis for congressional-executive 
agreements in the area of foreign trade. According to Judge 
Mollison:

    \99\ 169 F. Supp. 268 (Cust. Ct. 1958), aff'd, 257 F. 2d 472

by the Reciprocal Trade Agreements Act of 1934, 48 Stat. 943.
    \102\ 169 F. Supp. at 278-280.
---------------------------------------------------------------------------
          The decision in Field v. Clark * * * is supporting 
        authority for the view of Congress, when it enacted the 
        Reciprocal Trade Agreements Act of 1934 [adding section 
        350(a) to the Tariff Act of 1930], that it had the 
        authority to authorize and empower the President, under 
        prescribed standards and upon specified limitations 
        upon his discretion, to negotiate and conclude 
        reciprocal trade agreements and to make them effective 
        by proclamation. The effect of the decision in Field v. 
        Clark, coming after six of the ten reciprocal trade 
        agreements had been concluded and made effective by 
        proclamation, was an approval of such trade agreements 
        and the exercise of such Executive authority and 
        practice.
          * * * It can hardly be doubted that the Congress has 
        the authority, in regulating foreign trade and 
        commerce, to authorize the President, under prescribed 
        standards and limitations, to negotiate, conclude, and 
        make effective by proclamation reciprocal trade 
        agreements lowering customs duties in return for 
        concessions granted the United States.\103\

    \103\ Ibid. at 287-288

    On appeal the U.S. Court of Customs and Patent Appeals 
affirmed the holding of the U.S. Customs Court and further 
amplified the constitutional doctrine supporting congressional-
executive agreements in the area of foreign trade:
          * * * From reading the act, it is apparent that 
        Congress concluded that the promotion of foreign trade 
        required that the tariff barriers in this and other 
        countries be modified on a negotiated basis. Since the 
        President has the responsibility of conducting the 
        foreign affairs of this country generally, it gave to 
        him the added responsibility of negotiating the 
        agreements in pursuance of the spirit of the act. Such 
        a procedure is not without precedent nor judicial 
        approval [citing, inter alia, the Altman and Louis Wolf 
        cases, supra] \104\
---------------------------------------------------------------------------
    \104\ 275 F. 2d at 483. The court also relied on United States v. 
Curtis-Wright Export Corp., 299 U.S. 304 (1936); United States v. 
Belmont, 301 U.S. 324 (1937), and United States v. Pink, 315 U.S. 203 
(1942). For a discussion of these cases, see text accompanying notes 
135-144 and 151-152, infra.

    The question whether trade agreements can constitutionally 
be entered into as congressional-executive agreements rather 
than treaties has arisen in a judicial challenge to the North 
American Free Trade Agreement (NAFTA), in which it was alleged 
that the failure to use the treaty process rendered the 
agreement and its implementing legislation unconstitutional. In 
Made in the USA Foundation v. United States, a Federal District 
Court held in July 1999 that ``the President had the authority 
to negotiate and conclude NAFTA pursuant to his executive 
authority and pursuant to the authority granted to him by 
Congress in accordance with the terms of the Omnibus Trade and 
Competitiveness Act of 1988 * * * and section 151 of the Trade 
Act of 1974 * * * and as further approved by the [NAFTA] 
Implementation Act.'' \105\ The court concluded that the 
foreign commerce clause, combined with the necessary and proper 
clause and the President's Article II foreign relations power, 
was a constitutionally sufficient basis for the NAFTA:
---------------------------------------------------------------------------
    \105\ Made in the USA Foundation et al. v. United States, 56 F. 
Supp. 2d 1226 (N.D. Ala 1999). The decision has been appealed to the 
U.S. Court of Appeals for the Eleventh Circuit.
    The issue had earlier emerged during Congress' consideration in 
1994 of implementing legislation for trade agreements concluded during 
the GATT Uruguay Round of Multilateral Trade Negotiations. The question 
originally was posed because of the perceived effect of the agreements 
on states. The agreements were negotiated and submitted to Congress for 
expedited approval and implementation pursuant to the statutes cited in 
the Made in the USA Foundation case, that is, the Omnibus Trade and 
Competitiveness Act of 1988, Public Law 100-418, as amended, and 
section 151 of the Trade Act of 1974, which together required an 
``implementing bill'' containing a provision expressly approving the 
agreements as well as any statutory provisions ``necessary or 
appropriate'' to implement them. The agreements were ultimately 
approved by both Houses of Congress in the Uruguay Round Agreements 
Act, Public Law 103-465. Legal arguments and discussion may be found in

        debatable, the plenary scope of the Commerce Clause is 
        clear. There exists no reason to apply a limiting 
        construction upon the Foreign Commerce Clause or to 
        assume that the Clause was not meant to give Congress 
        the power to approve those agreements that are 
        `necessary and proper' in regulating foreign commerce. 
        It is impossible to definitively conclude that the 
        Framers intended the regulation of foreign commerce to 
        be subject to the rigors of the Treaty clause procedure 
        when commercial agreements with foreign nations are 
        involved. Given the [Supreme] Court's language in 
        Gibbons v. Ogden, the power of Congress to regulate 
        foreign commerce with foreign nations is so extensive 
        that it is reasonably arguable * * * that no `treaty' 
        affecting commerce with foreign nations is valid unless 
        adopted by Congress as a whole. In the absence of 
        specific limiting language in or relating to the Treaty 
        Clause, I am led to conclude that the foreign commerce 
        power of Congress is at least concurrent with the 
        Treaty Clause power when an agreement, as is the case 
        here, is dominated by provisions specifically related 
        to foreign commerce and has other provisions which are 
        reasonably `necessary and proper' for `carrying all 
        others into execution.' * * * Further, I note that the 
        President, in negotiating the Agreement in connection 
        with the fast track legislation, is acting pursuant to 
        his constitutional responsibility for conducting the 
        Nation's foreign affairs and pursuant to a grant of 
        authority from Congress.\106\

    \106\ Ibid. at 1319-22 (citations omitted). Gibbons v. Ogden, 22 
U.S. 1 (1824) recognized the plenary nature of Congress' power under 
the commerce clause. The court also stated that it had been persuaded 
by language in Edwards v. Carter, 580 F. 2d 1055, 1057-58 (D.C. Cir.), 
cert. denied, 436 U.S. 907 (1978), addressing concurrent power under 
the property clause (U.S. Constitution, Article IV, Section 3, Clause 
2). Edwards considered whether the clause, which authorizes Congress 
``to dispose of and make all needful Rules and Regulations respecting 
the Territory or other Property belonging to the United States,'' 
prevented the President and the Senate from transferring ownership of 
the Panama Canal pursuant to a treaty. The Edwards court stated in part 
that ``on its face, the Property Cause is intended not to restrict the 
scope of the Treaty Clause, but, rather is intended to permit Congress 
to accomplish through legislation what may concurrently be accomplished 
through other means provided in the Constitution.'' 580 F. 2d at 1058, 
as quoted in 56 F. Supp. 2d 1309.

    The Supreme Court earlier addressed the question of 
congressional-executive agreements in Weinberger v. Rossi,\107\ 
where it held that the term ``treaty,'' as used in a statute 
prohibiting employment discrimination against U.S. citizens on 
American military bases abroad unless permitted by ``treaty,'' 
embraced a base labor agreement between the United States and 
the Philippines authorizing the preferential hiring of Filipino 
nationals.\108\ The Court deemed the issue as ``solely one of 
statutory interpretation'' and noted, inter alia, the 
imprecision of Congress' use of the term ``treaty'' in various 
legislative enactments and the rule of construction favoring 
the harmonization of statutory requirements with the Nation's 
international obligations.\109\

    \108\ At issue in the case was the scope of section 106 of Public 
Law 92-129, 85 Stat. 355, 5 U.S.C. Sec. 7201 note, prohibiting 
employment discrimination of the type described. Earlier, in 1944, 
Congress had authorized the President, ``by such means as he finds 
appropriate,'' to acquire by negotiations with the President of the 
Philippines, military bases ``he may deem necessary for the protection 
of the Philippine Islands and of the United States.'' 22 U.S.C. 
Sec. 1392. Pursuant to this authority, the President concluded the 
Military Bases Agreement of March 14, 1947, 62 Stat. 4019, as well as 
the Base Labor Agreement of May 27, 1968, 19 U.S.T. 5892, the latter 
providing for the preferential hiring of Filipino citizens at American 
military facilities in the Philippines.

12 agreements in addition to the [Philippine base labor agreement] 
providing for preferential hiring of local national on United States 
military [bases] over seas. Since the time of the enactment of 
Sec. 106, four more such agreements have been concluded, and none of 
these were submitted to the Senate for its advice and consent * * * We 
think that some affirmative expression of congressional intent to 
abrogate the United States' international obligations is required in 
order to construe the word `treaty' in Sec. 106 as meaning only Article 
II treaties.'' Ibid. at 32.

    The use of congressional-executive agreements in the 
extradition area was recently affirmed in Ntakirutimana v. 
Reno, which challenged the constitutionality of the 1995 
extradition agreement between the United States and the 
International Criminal Tribunal for Rwanda.\110\ The agreement 
had been entered into as an executive agreement and implemented 
pursuant to Section 1342 of Public Law 104-106.\111\ Petitioner 
argued that a treaty was constitutionally required for an 
extradition, but the Federal Circuit Court of Appeals 
disagreed, finding that neither the text of the Constitution, 
constitutional history, nor historical practice supported such 
a requirement. Addressing the Supreme Court's ruling in 
Valentine v. United States \112\ that executive power to 
extradite must be based in a statute or a treaty, the court 
concluded that the required authorization could be found in 
Public Law 104-106, which, along with the agreement, created 
the constitutionally valid ``congressional-executive 
agreement'' used in this situation.

    From the foregoing review of the practice and case law 
associated with congressional-executive agreements, it would 
seem that the constitutionality of this mode of agreement-
making is well established. Notwithstanding that the text of 
the Constitution confers no explicit authority for the making 
of congressional-executive agreements, such agreements have 
been authorized frequently by Congress over the years on a wide 
variety of subjects. Similarly, courts have been little 
troubled by theoretical considerations and have sustained such 
agreements largely on the basis of the actual practice of the 
political branches of the government and the cumulative weight 
of prior judicial decisions. Where the constitutionality of a 
congressional-executive agreement was directly challenged, the 
commerce clause coupled with the necessary and proper clause 
and the President's foreign affairs power was held to provide 
an adequate constitutional basis for a trade agreement that 
took this form.\113\ Moreover, it appears to be the majority 
view of legal scholars that congressional-executive agreements 
and treaties are wholly interchangeable modes of agreement-
making for the United States, although this proposition has 
been periodically questioned where the ``interchange'' is 
initiated by the President in his discretion rather than by 
prior congressional authorization.\114\
---------------------------------------------------------------------------
    \113\ For a cogent argument that the combined foreign affairs 
powers of the Congress and the President would prove sufficient to 
sustain congressional-executive agreements, see McDougal and Lans, pp.

involving the United States, Egypt, and Israel, as ``executive 
agreements.'' Congressional Record, v. 121, 1975, pp. 36718-36731 and

---------------------------------------------------------------------------

                     agreements pursuant to treaties

     Agreements in this category comprise those which are 
expressly authorized by the text of an existing treaty or whose 
making may be reasonably inferred from the provisions of a 
prior treaty. Numerous agreements pursuant to treaties have 
been concluded by the Executive, particularly of an 
administrative nature, to implement in detail generally worded 
treaty obligations. Early agreements of this type consist of 
instruments accepting the results of boundary surveys mandated 
by a pre-existing treaty, accepting the accession of additional 
parties to a previously concluded treaty, or implementing 
transit rights across foreign territory as envisioned by a 
treaty of earlier date.\115\ Modern examples of agreements 
pursuant to treaties may be found in the many arrangements and 
understandings implementing the North Atlantic Treaty 
Organization (NATO) Treaty.\116\

    \115\ See Crandall, pp. 117-119.

    Agreements concluded pursuant to existing treaties have 
occasionally provoked controversy when it has been alleged that 
particular agreements either required Senate approval in treaty 
form or were otherwise not within the purview of an existing 
treaty.\117\ While the President's authority to conclude such 
agreements seems well-established, the constitutional doctrine 
underlying his power is seldom detailed by legal commentators 
or by the courts. It has been suggested that sufficient 
authority may be found in the President's duty under Article 
II, Section 3, of the Constitution to ``take care that the laws 
[i.e., treaty law] be faithfully executed.'' \118\ If the 
making of such agreements is indeed sustainable on this ground, 
then the instruments technically would seem more properly 
characterized as Presidential or sole executive agreements in 
view of the reliance upon one of the Executive's independent 
powers under Article II of the Constitution.

    On the other hand, an alternate legal basis is suggested by 
Wilson v. Girard,\119\ where the Supreme Court seemed to find 
sufficient authorization in the Senate's consent to the 
underlying treaty. The Court's decision was predicated on the 
following factual chronology. Pursuant to a 1951 bilateral 
security treaty,\120\ Japan and the United States signed an 
administrative agreement \121\ which became effective on the 
same date as the security treaty and which was considered by 
the Senate before consenting to the treaty. The administrative 
agreement provided that once a NATO Status of Forces Agreement 
concerning criminal jurisdiction came into effect, the United 
States and Japan would conclude an agreement with provisions 
corresponding to those of the NATO Arrangements. Accordingly, 
subsequent to the entry into force of the NATO Agreement,\122\ 
the United States and Japan effected a protocol agreement \123\ 
containing provisions at issue in the case at bar. In 
sustaining both the administrative agreement and the protocol 
agreement, the Court stated that:

                presidential or sole executive agreements

    Agreements concluded exclusively pursuant to the 
President's independent authority under Article II of the 
Constitution may be denominated Presidential or sole executive 
agreements. Unlike congressional-executive agreements or 
agreements pursuant to treaties, Presidential agreements lack 
an underlying legal basis in the form of a statute or treaty.
    Numerous Presidential agreements have been concluded over 
the years on the basis of the President's independent 
constitutional authority. Agreements of this type deal with a 
variety of subjects and reflect varying degrees of formality. 
Many Presidential agreements, of course, pertain to relatively 
minor matters and are the subject of little concern. Other 
agreements, however, have provoked substantial interbranch 
controversy, notably between the Executive and the Senate.
    Some idea of both the modern scope and contentious nature 
of Presidential agreements may be gained by noting that such 
agreements were responsible for the open door policy toward 
China at the beginning of the 20th century,\125\ the effective 
acknowledgment of Japan's political hegemony in the Far East 
pursuant to the Taft-Katsura Agreement of 1905 and the Lansing-
Ishii Agreement of 1917,\126\ American recognition of the 
Soviet Union in the Litvinov Agreement of 1933,\127\ the 
Destroyers-for-Bases Exchange with Great Britain prior to 
American entry into World War II,\128\ the Yalta Agreement of 
1945, a secret portion of which made far-reaching concessions 
to the Soviet Union to gain Russia's entry into the war against 
Japan,\129\ the 1973 Vietnam Peace Agreement,\130\ and, more 
recently, the Iranian Hostage Agreement of 1981.\131\

---------------------------------------------------------------------------
    As previously indicated, legal authority supporting the 
conclusion of Presidential agreements may be found in the 
various foreign affairs powers of the President under Article 
II of the Constitution. In a given instance, a specific 
agreement may be supportable on the basis of one or more of 
these independent executive powers.
    One possible basis for sole executive agreements seem to 
lie in the President's general ``executive power'' under 
Article II, Section 1, of the Constitution. Early judicial 
recognition of this power in the context of Presidential 
agreements, and perhaps the earliest judicial enforcement of 
this mode of agreement-making as well, was accorded by the 
Supreme Court of the Territory of Washington in Watts v. United 
States.\132\ The agreement at issue was concluded between the 
United States and Great Britain in 1859 and provided for the 
joint occupation of San Juan Island pending a final adjustment 
of the international boundary by the parties.\133\ The court 
stated that ``[t]he power to make and enforce such a temporary 
convention respecting its own territory is a necessary incident 
to every national government, and adheres where the executive 
power is vested.'' \134\

establishing the agreement for the joint occupation of the island was

Section 2 Clause 1). The Watts case is further discussed in the text 
accompanying note 160 infra.
---------------------------------------------------------------------------
    The President's executive power was later acknowledged in 
broad terms in United States v. Curtiss-Wright Export 
Corporation \135\ where the U.S. Supreme Court referred to the 
``very delicate, plenary, and exclusive power of the President 
as the sole organ of the federal government in the field of 
international relations.'' \136\ Although no agreement was at 
issue in Curtiss-Wright, the quoted language was subsequently 
applied by the Court in United States v. Belmont \137\ to 
validate the Litvinov Agreement of 1993, supra, wherein the 
parties settled mutually outstanding claims incident to formal 
American recognition of the Soviet Union. Concerning this 
agreement, the Court declared that:
---------------------------------------------------------------------------
    \135\ 299 U.S. 304 (1936).
    \136\ Ibid. at 320.
    \137\ 301 U.S. 324 (1937).
---------------------------------------------------------------------------
          * * * [I]n respect of what was done here, the 
        Executive had authority to speak as the sole organ of 
        the government. The assignment and the agreements in 
        connection therewith did not as in the case of 
        treaties, as that term is used in the treaty-making 
        clause of the Constitution (Art. II, Sec. 2), require 
        the advice and consent of the Senate.\138\
---------------------------------------------------------------------------
    \138\ Ibid. at 330.

    Similarly, in United States v. Pink,\139\ the Court again 
approved the Litvinov Agreement on the ground that ``[p]ower to 
remove such obstacles to full recognition as settlement of 
claims * * * certainly is a modest implied power of the 
President who is the `sole organ of the federal government in 
the field of international relations.' '' \140\ More recently, 
in Dames & Moore v. Regan,\141\ the Court relied upon, inter 
alia, the Pink case to sustain President Carter's suspension of 
claims pending in American courts against Iran as required by 
the Hostage Release Agreement of 1981, supra, and, more 
directly, by Executive order.\142\ In light of Pink, the Court 
indicated that ``prior cases * * * have recognized that the 
President does have some measure of power to enter into 
executive agreements without obtaining the advice and consent 
of the Senate.'' \143\ Moreover, the Court's decision was 
heavily influenced by a finding the general tenor of existing 
statutes reflected Congress' acceptance of a broad scope for 
independent executive action in the area of international 
claims settlement agreements.\144\

    \144\ The Court found that related statutes, though not authorizing 
the President's action, might be viewed as inviting independent 
Presidential measures in a situation such as the one at issue ``at 
least * * * where there is no contrary indication of legislative intent 
and when, as here, there is a history of congressional acquiescence of 
the sort engaged in by the President,'' namely, claims settlement by 
executive agreement. Ibid. at 677-682. In Barquero v. United States, 18 
F. 3d 1311 (5th Cir. 1994), Dames & Moore criteria were used by a 
Federal Circuit Court of Appeals to find an alternative constitutional 
basis for the President's entry into tax information exchange 
agreements with countries that were not ``beneficiary countries'' under 
the Caribbean Basin Economic Recovery Act. The court primarily held, 
however, that the agreements were authorized under the 1986 Tax Reform 
Act.
---------------------------------------------------------------------------
    A second Article II power potentially available to the 
President for purposes for concluding sole executive agreements 
appears to lie in Article II, Section 2, Clause 1, of the 
Constitution which provides that the President shall be 
``Commander-in-Chief of the Army and Navy.'' Cautious 
acceptance of the President's power to conclude agreements 
pursuant to this power is reflected in dictum of the Supreme 
Court in Tucker v. Alexandroff \145\ where the Court, after 
noting previous instances in which the Executive unilaterally 
had granted permission for foreign troops to enter the United 
States, declared that ``[w]hile no act of Congress authorized 
the Executive Department to permit the introduction of foreign 
troops, the power to give such permission without legislative 
assent was probably assumed to exist from the authority of the 
President as commander in chief of the military and naval 
forces of the United States.'' \146\

---------------------------------------------------------------------------
    The treaty clause of the Constitution (Article II, Section 
2, Clause 2), in empowering the President to make treaties with 
the consent of the Senate, may itself be viewed as supporting 
authority for some types of sole executive agreements. The 
President's power under this clause, together with his 
constitutional role as sole international negotiator for the 
United States \147\ suggest the existence of ancillary 
authority to make agreements necessary for the conclusion of 
treaties. Intermediate stages of negotiations or temporary 
measures pending conclusion of a treaty may, for example, be 
reflected in protocols or modus vivendi.\148\ Although there 
appear to be no cases explicitly recognizing the treaty clause 
as authority for sole executive agreements, the Court's opinion 
in Belmont seems suggestive in acknowledging that there are 
many international compacts not always requiring Senate consent 
``of which a protocol [and] a modus vivendi are 
illustrations.'' \149\
---------------------------------------------------------------------------
    \147\ The Supreme Court indicated in the Curtiss-Wright case that 
the ``[President] alone negotiates. Into the field of negotiations the 
Senate cannot intrude; and Congress itself is powerless to invade 
it.'': 299 U.S. at 319.

---------------------------------------------------------------------------
    A fourth power of the President under Article II which is 
relevant to the conclusion of sole executive agreements lies in 
his authority to ``receive Ambassadors and other public 
Ministers'' (Article II, Section 3). To the extent that the 
receive clause is viewed as supporting the President's 
authority to ``recognize'' foreign governments,\150\ it is 
arguable that sole executive agreements may be concluded 
incident to such recognition. Although the Belmont and Pink 
cases appear to sustain the Litvinov Agreement principally on 
the basis of the President's general foreign affairs powers as 
Chief Executive or ``sole organ'' of the government in the 
field of international relations, the Court also seemed to 
emphasize that the agreement accorded American ``recognition'' 
to the Soviet Union. Thus, in Belmont the Court stated that:
---------------------------------------------------------------------------
    \150\ See Goldwater v. Carter, 617 F. 2d 697, 707-708 (D.C. Cir. 
1979), jud. vac. and rem. with directions to dismiss complaint, 444 
U.S. 996 (1979). Professor Henkin observes that ``[r]ecognition is 
indisputably the President's sole responsibility, and for many it is an 
`enumerated' power implied in the President's express authority to 
appoint and receive ambassadors.'' Henkin 1996, p. 220. See also 
Wright, Control of Foreign Relations, p. 133; Mathews, pp. 365-366; and 
McDougal and Lans, pp. 247-248.
---------------------------------------------------------------------------
          We take judicial notice of the fact that coincident 
        with the assignment [of Soviet claims against American 
        nationals to the United States government], the 
        President recognized the Soviet Government, and normal 
        diplomatic relations were established between that 
        government and the government of the United States, 
        followed by an exchange of ambassadors * * * The 
        recognition, establishment of diplomatic relations, the 
        assignment, and agreements with respect thereto, were 
        all parts of one transaction, resulting in an 
        international compact between the two governments. That 
        the negotiations, acceptance of the assignment and 
        agreements and understandings in respect thereof were 
        within the competence of the President may not be 
        doubted * * * [I]n respect of what was done here, the 
        Executive had authority to speak as the sole organ of 
        [the] government.\151\
---------------------------------------------------------------------------
    \151\ 301 U.S. at 330.

    Similarly, in Pink the Court declared that:
          ``What government is to be regarded here as 
        representative of a foreign sovereign state is a 
        political rather than a judicial question, and is to be 
        determined by the political department of the 
        government'' * * * That authority is not limited to a 
        determination of the government to be recognized. It 
        includes the power to determine the policy which is to 
        govern the question of recognition * * * Recognition is 
        not always absolute; it is sometimes conditional * * * 
        Power to remove such obstacles to full recognition as 
        settlement of claims of our nationals * * * Unless such 
        a power exists, the power of recognition might be 
        thwarted or seriously impaired. No such obstacles can 
        be placed in the way of rehabilitation of relations 
        between this country and another nation, unless the 
        historic conception of the powers and responsibilities 
        of the president in the conduct of foreign affairs * * 
        * is to be drastically revised.\152\
---------------------------------------------------------------------------
    \152\ 315 U.S. at 229-230. See also Dole v. Carter, 444 F. Supp. 
1065 (D. Kan. 1977), motion for injunction pending appeal denied, 569 
F. 2d 1108 (10th Cir. 1977), where the district court relied on the 
President's recognition power and his general ``sole organ'' executive 
authority to validate a Presidential agreement transferring Hungarian 
coronation regalia to the Republic of Hungary. On appeal, however, the 
Court of Appeals ``decline[d] to enter into any controversy relating to 
distinctions which may be drawn between executive agreements and 
treaties'' and adjudged the issue a nonjusticiable political question.

    A fifth source of Presidential power under Article II 
possibly supporting the conclusion of sole executive agreements 
is the President's duty to ``take care that the laws be 
faithfully executed'' (Article II, Section 3). Although there 
appear to be no cases holding that the take care clause is 
specific authority for such agreements, legal commentators have 
asserted that the clause sanctions the conclusion of agreements 
in implementation of treaties.\153\ Moreover, it was early 
opined by Attorney General Wirt in 1822 that the President's 
duty under this constitutional provision extends not only to 
the Constitution, statutes, and treaties of the United States 
but also to ``those general laws of nations which govern the 
intercourse between the United States and foreign nations.'' 
\154\ This view appears to have been accepted subsequently by 
the Supreme Court in In re Neagle,\155\ where it was suggested 
in dictum that the President's responsibility under the clause 
includes the enforcement of ``rights, duties, and obligations 
growing out of * * * our international relations * * *'' \156\ 
Accordingly, it has been argued that the clause ``sanctions 
agreements which are necessary to fulfill [non-treaty] 
international obligations of the United States.'' \157\

be found in Malloy, Treaties, v. 2, p. 2006. Concerning the use of the 
``take care'' clause as authority for executive implementation of 
international law, Professor Henkin notes that-- * * * Writers have not 
distinguished between (a) authority to carry out the obligations of the 
United States under treaty or customary law (which can plausibly be 
found in the `take care' clause); (b) authority to exercise rights 
reserved to the United States by international law or given it by 
treaty; and (c) authority to compel other states to carry out their 
international obligations to the United States. Henkin 1996, p. 347, n. 
54.
---------------------------------------------------------------------------
    Sole executive agreements validly concluded pursuant to one 
or more of the President's independent powers under Article II 
of the Constitution may be accorded status as Supreme Law of 
the Land for purposes of superseding any conflicting provisions 
of state law. As explained by the Supreme Court in Belmont:
          Plainly, the external powers of the United States are 
        to be exercised without regard to the state laws or 
        policies. The supremacy of a treaty in this respect has 
        been recognized from the beginning * * * And while this 
        rule in respect of treaties is established by the 
        express language of cl. 2, Art. VI, of the 
        Constitution, the same rule would result in the case of 
        all international compacts and agreements from the very 
        fact that complete power over international affairs is 
        in the national government and is not and cannot be 
        subject to any curtailment or interference on the part 
        of the several states.\158\

    However, notwithstanding that treaties and Federal statutes 
are treated equally by the Constitution with legal primacy 
accorded the measure which is later in time,\159\ the courts 
have been reluctant to enforce Presidential agreements in the 
face of prior congressional enactments. Judicial uncertainty 
was early evidenced in Watts v. United States, supra, where the 
Supreme Court of the Territory of Washington, after affirming 
on the basis of the President's ``executive power'' the 
validity of an agreement with Great Britain providing for the 
joint occupation of San Juan Island, tentatively enforced the 
agreement against a prior Federal law defining the government 
of the territory. According to the court:
---------------------------------------------------------------------------
    \159\ Whitney v. Robertson, 124 U.S. 190 (1888).
---------------------------------------------------------------------------
          Such conventions are not treaties within the meaning 
        of the Constitution, and, as treaties supreme law of 
        the land, conclusive on the court, but they are 
        provisional arrangements, rendered necessary by 
        national differences involving the faith of the nation 
        and entitled to the respect of the courts. They are not 
        a casting of the national will into the firm and 
        permanent condition of law, and yet in some sort they 
        are for the occasion an expression of the will of the 
        people through their political organ, touching the 
        matters affected; and to avoid unhappy collision 
        between the political and judicial branches of the 
        government, both which are in theory inseparably all 
        one, such an expression to a reasonable limit should be 
        followed by the courts and not opposed, though 
        extending to the temporary restraint or modification of 
        the operation of existing statutes. Just as here, we 
        think, this particular convention respecting San Juan 
        should be allowed to modify for the time being the 
        operation of the organic act of this Territory 
        (Washington) so far forth as to exclude to the extent 
        demanded by the political branch of the government of 
        the United States, in the interest of peace, all 
        territorial interference for the government of that 
        island.\160\
---------------------------------------------------------------------------

Congress had been ``fully apprised'' of the situation by the President 
and noted tacit congressional acquiescence for a long term of years. 
Ibid., p. 293.

    Decisions by lower Federal courts of more recent date, 
however, have voided sole executive agreements which were 
incompatible with pre-existing Federal laws. Thus, in United 
States v. Guy W. Capps, Inc.,\161\ a U.S. Circuit Court of 
Appeals refused to enforce a Presidential agreement concerning 
the importation of Canadian potatoes into the United States 
inasmuch as the agreement contravened the requirements of the 
Agricultural Act of 1948.\162\ According to the court, ``* * * 
whatever the power of the executive with respect to making 
executive trade agreements regulating foreign commerce in the 
absence of action by Congress, it is clear that the executive 
may not through entering into such an agreement avoid complying 
with a regulation prescribed by Congress.'' \163\ The court's 
rationale for this conclusion was grounded upon Congress' 
expressly delegated authority under Article I, Section 8, 
Clause 3, of the Constitution to regulate foreign commerce (as 
reflected in the statute in the present case) and upon the 
following statement from Justice Jackson's frequently quoted 
concurring opinion in Youngstown Sheet & Tube Co. v. Sawyer:

          When the President takes measures incompatible with 
        the expressed or implied will of Congress, his power is 
        at its ebb, for then he can rely only upon his own 
        constitutional powers minus any constitutional powers 
        of Congress over the matter. Courts can sustain 
        exclusive Presidential control in such a case only by 
        disabling the Congress from acting upon the subject. 
        Presidential claim to a power at once so conclusive and 
        preclusive must be scrutinized with caution, for what 
        is at stake is the equilibrium established by our 
        constitutional system.\165\

    Similar holdings have occurred in subsequent cases on the 
authority of Guy Capps. In Seery v. United States,\166\ for 
example, the U.S. Court of Claims denied enforcement of a 
Presidential agreement settling post-World War II claims with 
Austria \167\ in the face of prior Federal law authorizing suit 
against the United States on constitutional claims.\168\ The 
court declared that:

          * * * It would indeed be incongruous if the Executive 
        Department alone, without even the limited 
        participation by Congress which is present when a 
        treaty is ratified, could not only nullify the Act of 
        Congress consenting to suit on Constitutional claims, 
        but, by nullifying that Act of Congress, destroy the 
        constitutional right of a citizen. In United States v. 
        Guy W. Capps * * * the court held that an executive 
        agreement which conflicted with an Act of Congress was 
        invalid.\169\

    Reference may also be made to Swearingen v. United States 
\170\ where a Federal District Court treated the Agreement in 
Implementation of Article III of the Panama Canal Treaty of 
1977 \171\ as a sole executive agreement, and, as such, void 
for purposes of conferring an income tax exemption on American 
employees of the Panama Canal Commission in derogation of 
Section 61(a) of the Internal Revenue Code.\172\ The rule of 
the Guy Capps case is also reflected in the Department of 
State's Circular 175 procedure governing the making of 
international agreements,\173\ as well as in the American Law 
Institute's current Restatement (Third) of the Foreign

    Notwithstanding that the rule of the Guy Capps case appears 
to enjoy general acceptance, contrary arguments have been 
advanced by other authorities, including the just cited 
Restatement (Third).\175\ The latter thus states that:
---------------------------------------------------------------------------
    \175\ Ibid.
---------------------------------------------------------------------------
          * * * it has been argued that a sole executive 
        agreement within the President's constitutional 
        authority is federal law, and United States 
        jurisprudence has not known federal law of different 
        constitutional status. ``All Constitutional acts of 
        power, whether in the executive or in the judicial 
        department, have as much legal validity and obligation 
        as if they proceeded from the legislature.'' The 
        Federalist No. 64 (Jay), cited in United States v. 
        Pink, supra, 315 U.S. at 230 * * * See Henkin, Foreign 
        Affairs and the Constitution 186, 432-33 (1972). Of 
        course, even if a sole executive agreement were held to 
        supersede a statute, Congress could reenact the statute 
        and thereby supersede the intervening executive 
        agreement as domestic law.\176\
---------------------------------------------------------------------------
    \176\ Ibid.

    The precedential effect of the Guy Capps rule may also be 
somewhat eroded by judicial dicta suggesting that the circuit 
court's opinion in the case was ``neutralized'' by the Supreme 
Court's affirmance on other grounds \177\ and that the question 
as to the effect of a Presidential agreement upon a prior 
conflicting act of Congress has ``apparently not yet been 
completely settled.'' \178\ Moreover, in the two cases which 
have specifically adhered to the Guy Capps rule--Seery and 
Swearingen--the courts, respectively, were either strongly 
influenced by Bill of Rights considerations or failed to 
consider the possibility that the agreement in issue may have 
effectively received the sanction of the Senate as an agreement 
pursuant to an existing treaty. It appears, therefore, that the 
law on this point may yet be in the course of further 
development.

     V. NEGOTIATION AND CONCLUSION OF INTERNATIONAL AGREEMENTS \1\

                              ----------                              

    Treatymaking begins with the negotiation and conclusion or 
signing of an agreement and ends with its ratification or 
acceptance as binding by the parties and its entry into force. 
This chapter examines the first stage, negotiation and 
conclusion.

                             A. Negotiation

    The negotiation of a treaty is the process by which the 
representatives of governments agree on the substance, terms, 
and wording of an international agreement. The word 
``negotiation'' has been defined as ``the exchange and 
discussion of proposals by the representatives of the parties 
concerned with a view to reaching a mutually acceptable 
agreement.'' \2\

---------------------------------------------------------------------------
    Nations negotiate and conclude treaties through individuals 
who have been issued ``full powers'' to represent their states 
for that purpose or are otherwise clearly intended to represent 
their states. Under international law, heads of state, heads of 
government, or foreign ministers are accepted as representing 
their states without a ``full powers'' document. Similarly, 
chiefs of diplomatic missions are considered representatives 
for purposes of negotiating a treaty with the state to which 
they are assigned, as are accredited representatives to 
international organizations and conferences for purposes of 
adopting a treaty text within those groups.\3\ U.S. practice is 
that a ``full power'' is not usually issued for conclusion of 
an international agreement other than a treaty.\4\

    In the United States, the actual negotiation of treaties 
and other international agreements is widely recognized as 
being within the power of the President. One authority calls 
negotiation ``a Presidential monopoly.'' \5\ Others argue that 
the Senate's advice and consent function applies before and 
during the negotiations as well as prior to ratification.\6\

---------------------------------------------------------------------------
    Article II, Section 2 of the Constitution provides that the 
President ``shall have Power, by and with the Advice and 
Consent of the Senate, to make Treaties, provided two-thirds of 
the Senators present concur.'' The President's control of 
negotiations also springs from three other provisions of the 
Constitution which result in his being the official channel of 
communications with other nations. Article II, Section 2 states 
that the President ``shall nominate, and by and with the advice 
and consent of the Senate, shall appoint ambassadors, other 
public ministers and consuls * * *.'' Section 3 of Article II 
provides that the President ``shall receive ambassadors and 
other public ministers.'' This power has made the President 
``the sole mouthpiece of the nation in its dealings with other 
nations.'' \7\ Finally, Article II, Section 1, provides: ``The 
executive power shall be vested in a President * * *.''
---------------------------------------------------------------------------
    \7\ Annotated Constitution, p. 541.
---------------------------------------------------------------------------
    The President or his representative begins the process of 
negotiations by inviting representatives of another nation, or 
responding to another country's invitation, to discuss 
proposals for an agreement. The President nominates and, with 
Senate advice and consent, appoints a person, usually an 
ambassador, minister, or foreign service officer, or delegation 
to represent the United States. He issues the negotiator ``full 
powers'' (a document certifying that the individual represents 
the United States) and provides instructions on the objectives 
and scope of the negotiations. He determines whether and when 
the text is signed by the United States.
    Nonetheless, during the negotiation phase Congress 
frequently plays a part. The Department of State procedures for 
negotiating treaties include timely and appropriate 
consultation with congressional leaders and committees as an 
objective. The procedures provide for consultations on the 
intention to negotiate significant new agreements, the form of 
the agreement, legislation that might be necessary, and other 
developments concerning treaties.\8\

text of Circular 175 procedures is contained in Appendix 4 of this 
volume. See also discussion in Chapter X.
---------------------------------------------------------------------------
    If the terms ``negotiation and conclusion'' of a treaty are 
used in a broader sense to include all the aspects of 
``making'' a treaty prior to the decision on ratification, 
clearly there are other aspects of this process in which the 
Senate or the entire Congress may participate. These include 
proposing a subject for a treaty to the President, advising and 
consenting on the appointment of an ambassador or minister to 
conduct the negotiations, and participating in the negotiations 
as observers or advisers to U.S. delegations. Some contend 
Senate attachment of conditions to its advice and consent 
constitutes an additional stage in the negotiating process.

                               logan act

    One statute passed by Congress in 1799, the Logan Act, 
appears to have strengthened executive branch control over 
negotiations by prohibiting unauthorized citizens from 
initiating or carrying out correspondence or intercourse with 
foreign governments on disputes with the United States. The 
Logan Act was enacted into positive law in the U.S. Code on 
June 25, 1948, and states:
    Private correspondence with foreign governments

    The law was enacted after a private citizen, Dr. George 
Logan, traveled to France and attempted to end the plundering 
of American merchant ships authorized by the French director of 
the revolutionary government. Although there have been no known 
prosecutions under the Act and only one indictment, there have 
been several judicial and congressional references to it, 
indicating, in the words of one analyst, that the Act ``has not 
been forgotten and that it is at least a political weapon 
against any one who without authority interferes in the foreign 
relations of the United States.'' \10\

the Senate passed an amendment supporting ``the enforcement of 
any applicable statutes not excluding the Logan Act or any 
other Act that may be violated in the course of private

---------------------------------------------------------------------------
    One issue is whether Members of Congress fit in the 
category of private citizens, and whether their communication 
with foreign governments would be ``unauthorized by the United 
States.'' These were addressed by the Department of State in 
1975. Assistant Secretary of State for Congressional Relations 
Robert J. McCloskey wrote that certain contacts of Senators 
John Sparkman and George McGovern with Cuban officials were not 
inconsistent with the Logan Act. The opinion stated:
          The clear intent of [the Logan Act] is to prohibit 
        unauthorized persons from intervening in disputes 
        between the United States and foreign governments. 
        Nothing in Section 953, however, would appear to 
        restrict members of the Congress from engaging in 
        discussions with foreign officials in pursuance of 
        their legislative duties under the Constitution. In the 
        case of Senators McGovern and Sparkman the executive 
        branch, although it did not in any way encourage the 
        Senators to go to Cuba, was fully informed of the 
        nature and purpose of their visit, and had validated 
        their passports for travel to that country.
          Senator McGovern's report of his discussions with 
        Cuban officials stated: ``I made it clear that I had no 
        authority to negotiate on behalf of the United States--
        that I had come to listen and learn * * *'' Senator 
        Sparkman's contacts with Cuban officials were conducted 
        on a similar basis. The specific issues raised by the 
        Senators (e.g., the Southern Airways case; Luis Tiant's 
        desire to have his parents visit the United States) 
        would, in any event, appear to fall within the second 
        paragraph of Section 953.
          Accordingly, the Department does not consider the 
        activities of Senators Sparkman and McGovern to be 
        inconsistent with the stipulations of Section 953.\13\

    Some Members of Congress have made efforts to repeal the 
Logan Act. Senator Edward Kennedy attempted to delete the 
measure from the 1978 bill to amend the U.S. criminal code (S. 
1437, 95th Cong.) but agreed to leave it in to prevent 
prolonged debate.\15\ Representative Anthony Beilenson 
introduced H.R. 7269 to repeal the Act on May 6, 1980, stating 
that there were fundamental constitutional problems with the 
Act and that its main use had been to ``allow periodic calls 
for prosecution motivated by opposition to the cause being 
expressed instead of actual concern about treason.'' \16\

           B. Initiative for an Agreement; Setting Objectives

    Within the United States, the proposal that the United 
States enter negotiations for an international agreement 
usually springs from the executive branch in the course of its 
diplomatic activities with other nations or in its 
administration of U.S. foreign policy. On occasion, however, 
Congress or its committees, subcommittees, or individual 
Members have formally or informally proposed that the President 
undertake negotiations or diplomatic actions aimed at achieving 
international agreement on a certain course of action. 
Proposals have been embodied both in sense of the Congress 
resolutions and in binding legislation.
    One of the best known examples of a congressional proposal 
is the Vandenberg Resolution that ultimately led to 
negotiations culminating in the North Atlantic Treaty. Adopted 
by the Senate on June 11, 1948, it expressed the sense of the 
Senate ``that this Government, by Constitutional processes, 
should particularly pursue'' certain objectives including:
          * * * Progressive development of regional and other 
        collective arrangements for individual and collective 
        self-defense in accordance with the purposes, 
        principles, and provisions of the Charter.
          * * * Association of the United States, by 
        constitutional process, with such regional and other 
        collective arrangements as are based on continuous and 
        effective self-help and mutual aid, and as affect its 
        national security.\18\
---------------------------------------------------------------------------
    \18\ S. Res. 239, 80th Cong., 2d Sess.

    The Senate Foreign Relations Committee which had, in close 
cooperation with the Department of State, worked out the 
resolution, later reported: ``Pursuant to this advice the 
President in July authorized the Secretary of State to enter 
into exploratory conversations on the security of the North 
Atlantic area. * * *'' \19\ The North Atlantic Treaty was 
signed on April 4, 1949, and received the advice and consent of 
the Senate.

    The Monroney Resolution suggesting the International 
Development Association is also often cited as a congressional 
initiative. On July 23, 1958, the Senate adopted a resolution 
introduced by Senator A.S. Mike Monroney suggesting that the 
administration study the possibility of proposing to other 
governments the establishment of an international development 
association as a soft-loan affiliate of the World Bank.\20\ The 
articles of agreement for this international financial 
institution were negotiated and submitted to Congress with a 
request for legislation to authorize U.S. participation. 
Congress authorized the participation on June 30, 1960.\21\

    The Seabed Arms Control Treaty, prohibiting the emplacement 
of nuclear weapons on the seabed and ocean floor, was in part a 
congressional initiative. Senator Claiborne Pell introduced 
resolutions in 1967 expressing the Senate's concern for 
reasonable rules governing the extraterritorial marine 
environment, and the need to negotiate a treaty to prohibit 
stationing nuclear weapons on the seabed.\22\ The treaty was 
signed in 1971, and the Senate approved it, by a vote of 83-0 
on February 15, 1972.

    Similarly, Congress helped initiate the Environmental 
Modification Convention. In July 1972, the U.S. Government 
renounced the use of climate modification techniques for 
hostile purposes, and beginning in 1972 both the House and 
Senate held hearings on a resolution to prohibit the use of any 
environmental or geophysical modification activity as a weapon 
of war. Senate Resolution 71, introduced by Senator Pell and 
passed July 11, 1973, stated the sense of the Senate that the 
U.S. Government ``should seek'' the agreement of other 
governments to a treaty along the following lines'' and 
suggested wording of a treaty. A Convention on the Prohibition 
of Military or Other Hostile Use of Environmental Modification 
Techniques was concluded on May 18, 1977, and entered into 
force for the United States January 17, 1980.
    Other congressional resolutions have also proposed 
negotiations. For example, on August 3, 1977, Congress stated 
the sense of the Congress ``that the President should initiate 
a major diplomatic initiative toward the creation of an 
international system of nationally held grain reserves which 
provides for supply assurance to consumers and income security 
to producers.'' \23\ On May 25, 1983, S. Res. 95 expressed the 
sense of the Senate that the President should initiate 
negotiations on a new long-term agreement on agricultural trade 
with the Soviet Union.

    \23\ Sec. 510, Public Law 95-105.
---------------------------------------------------------------------------
    On occasion the resolutions proposing negotiations have 
contained a reporting request or requirement. S. Res. 95 
mentioned above stated the sense of the Senate that the 
President should report to Congress as soon as practicable on 
the potential impact of the agreement on the U.S. economy. S. 
Res. 133, adopted April 18, 1975, called for the President to 
report within 30 days on efforts to promote a settlement in 
Vietnam.\24\

    \24\ S. Rept. 94-39.
---------------------------------------------------------------------------
    Congress also utilized binding legislation to authorize, 
call for, or suggest negotiations for international agreements. 
In the Trade Agreements Act of 1974, Congress urged the 
President to utilize the authority granted in order to 
negotiate trade agreements with other countries that would 
reduce and eliminate nontariff barriers. The Act specified 
negotiating objectives for the United States.\25\

    Section 36 of the Foreign Assistance Act of 1973 called for 
the President or his delegate to seek, as soon as possible, a 
revision of the Social Progress Trust Fund Agreement, between 
the United States and the Inter-American Development Bank, 
specifying revisions to be made. Section 36(e) stated, ``Not 
later than January 1, the President shall report to Congress on 
his action taken pursuant to this section.\26\ Section 39 of 
the same Act stated the sense of Congress that the United 
States should participate in efforts to alleviate world food 
shortages and that ``To this end, the President shall--'' among 
other things request member nations of the General Agreement on 
Tariffs and Trade to explore certain questions, consult and 
cooperate with appropriate international agencies in certain 
purposes, and report his findings and recommendations on the 
implementation of the section by December 31, 1974.

President within 180 days describing efforts to negotiate 
multilateral measures.\28\ The measure also provided that

    President Bush objected to some directives concerning 
negotiation of agreements in signing both Foreign Relations 
Authorization Acts enacted during his administration.\29\ As an 
example, section 102 of Public Law 101-246 prohibited the use 
of funds for any U.S. delegation to any meeting within the 
framework of the Conference on Security and Cooperation in 
Europe (CSCE), unless the U.S. delegation included individuals 
representing the Commission on Security and Cooperation in 
Europe. The commission was a legislative-executive body which 
had been established earlier by Congress. President Bush said 
the section ``impermissibly intrudes upon my constitutional 
authority to conduct our foreign relations and to appoint our 
Nation's envoys.'' \30\ Although President Bush stated that he 
would construe the measure as expressing the sense of the 
Congress but not imposing a binding legal obligation, 
representatives of the commission have been regularly included 
in delegations to meetings of what is now the Organization on 
Security and Cooperation in Europe.

                 C. Advice and Consent on Appointments

    Most treaties and international agreements are negotiated 
by ambassadors or foreign service officers already assigned to 
particular countries or functions.\31\
---------------------------------------------------------------------------
    \31\ This section is based in part on The Senate Role in Foreign

    Nevertheless, the Senate sometimes has an exclusive 
opportunity to advise on treaty negotiations at the outset, 
through the constitutional requirement that it advise and 
consent to appointments of ``ambassadors, other public 
ministers and consuls.'' \32\
---------------------------------------------------------------------------
    \32\ Constitution, Article II, Section 2, Clause 2.
---------------------------------------------------------------------------
    The requirement for Senate confirmation appears to have 
been a basic part of the plan to divide the foreign relations 
powers between Congress and the President, with a special role 
for the Senate in the making of treaties. The Constitution 
divides the power relating to making treaties and appointing 
ambassadors in essentially the same manner, although it 
requires a two-thirds majority only for treaties.
    At the time of the writing of the Constitution, there was 
reason to distribute the power to appoint ambassadors and 
ministers in the same fashion as the power to make treaties. 
Treaties were made by ambassadors with full powers from the 
sovereign, usually a king, who issued instructions relating to 
the treaty. If the ambassador stayed within his instructions, 
it was considered obligatory for the sovereign to ratify the 
treaty his emissary concluded.
    Under the doctrine of obligatory ratification, the only way 
the Senate could have a meaningful role in treatymaking was to 
participate during the negotiating stage or during the 
proposing stage when the instructions to the plenipotentiaries 
were being drawn up. Gradually, the Senate practice of 
approving treaties with reservations, the French Revolution, 
and moves toward democratic control in other countries, brought 
about a change in concept and ratification of a treaty came to 
be recognized as discretionary rather than obligatory.\33\

Development of Treaty-Making Procedure. Cambridge University Press,

---------------------------------------------------------------------------
    The Framers of the Constitution took into account the link 
between appointments and treaties. In discussing a proposal 
that ``no treaty shall be binding on the United States which is 
not ratified by a law'' and thus would have required the 
consent of the entire Congress, one delegate to the 
Constitutional Convention, according to Madison's notes, 
``thought there was something of solecism in saying that the 
acts of a Minister with plenipotentiary powers from one body 
should depend for ratification on another body.'' \34\ Another 
delegate, according to McHenry's notes for August 23, 1787, 
objected to requiring ratification by a law because ``a 
minister could not then be instructed by the Senate who were to 
appoint him, or if instructed there could be no certainty that 
the House of Representatives would agree to confirm what he 
might agree to under these instructions.\35\

---------------------------------------------------------------------------
    Early practice under the Constitution also indicates that 
the Framers expected that the Senate's confirmation of 
appointments of ambassadors and ministers would give the Senate 
a significant role in making treaties. Often nominations were 
submitted along with a description of the treaty the nominee 
was to seek. To illustrate, on January 11, 1792, President 
Washington nominated William Carmichael, the charge d'affaires 
at Madrid, and William Short, then charge d'affaires at Paris, 
to be commissioners plenipotentiary for negotiating a treaty 
with Spain concerning the navigation of the Mississippi, and 
they were confirmed by the Senate on January 24, 1792. In 
March, the President sent a memo to the Senate proposing to 
extend the negotiations to the subject of commerce, setting 
forth the instructions that would be given to the 
commissioners, and asking if the Senate would ``advise and 
consent to the extension of the powers of the commissioners, as 
proposed, and to the ratification of a treaty which shall 
conform to those instructions, should they enter into such a 
one.'' On March 16, 1792, the Senate passed a resolution giving 
its advice and consent to the extension of powers and stating 
that ``they will advise and consent to the ratification of such 
treaty as the said commissioners shall enter into with the 
Court of Spain in conformity to those instructions.'' \36\

    The practice of submitting the instructions for 
negotiations along with the nominations did not continue long. 
In the case of the nomination of John Jay to conclude a treaty 
with Great Britain in 1794, the Senate rejected a motion that 
the President be requested to inform the Senate of ``the whole 
business with which the provided envoy is to be charged.'' \37\ 
Nevertheless, the debate on the nomination indicated that the 
Senate ``passed not only upon the choice of the envoy but also 
upon the expediency of the mission itself.'' \38\

    In recent years the Senate or the Senate Foreign Relations 
Committee has on occasion used nominations as a vehicle for 
discussion of treaty negotiations. When Paul H. Nitze was 
nominated as ambassador while serving as the head of the U.S. 
Delegation to the Intermediate Range Nuclear Forces 
Negotiations, the committee held both a closed and open session 
with him. Ambassador Nitze had been in the post for 6 months 
with the personal rank of ambassador.\39\ Chairman of the 
Senate Foreign Relations Committee Charles Percy noted that the 
open hearing provided an opportunity to review the issues that 
involve arms control. In the nomination of Sol M. Linowitz for 
the rank of ambassador as personal representative of the 
President to the West Bank and Gaza Strip Autonomy 
Negotiations, the committee hearing covered problems relating 
to the Middle East and Mr. Linowitz's status as a ``special 
Government employee'' receiving no compensation.\40\

                    unconfirmed presidential agents

    A continuing problem has been the appointment or use of 
persons not confirmed by the Senate to negotiate international 
agreements. In such cases, the Senate does not have an 
opportunity to vote on the appointment or to advise on the 
mission for which he is appointed. The negotiator remains a 
personal agent of the President. Similarly, the Assistant to 
the President for National Security Affairs, also called the 
National Security Adviser, is not confirmed by the Senate, but 
on occasion conducts negotiations.
    The subject has been controversial through most of American 
history. For example, in 1888, a fisheries treaty with Great 
Britain was criticized in the Senate Foreign Relations 
Committee report and in Senate debate on the grounds that the 
negotiators had not been appointed by and with the consent of 
the Senate. Proponents of the treaty countered with a list 
showing that of the persons conducting negotiations for the 
United States since 1789, 438 had been appointed without Senate 
confirmation and only 35 had been confirmed.\41\

    One authority has attributed the initiation of the practice 
of appointing special, unconfirmed agents for negotiation of 
specific treaties to the President's embarrassment over the 
Senate refusal in 1813 to approve the nomination of Albert 
Gallatin, Secretary of the Treasury, as a member of the mission 
to negotiate the Treaty of Ghent until he had resigned his 
position as Secretary of the Treasury.\42\

---------------------------------------------------------------------------
    Recent Presidents have also decided not to submit some 
appointments of negotiators to the Senate, although in the 20th 
century such nominations were rarely rejected by the Senate, 
and none have been since World War II. Nevertheless the 
possibility remains that a nomination might not be approved. 
Several nominations have raised a controversy or not been acted 
upon, and two were unfavorably reported by the Foreign 
Relations Committee.\43\
---------------------------------------------------------------------------
    \43\ In 1981, the Senate Foreign Relations Committee reported 
unfavorably the nomination of Ernest W. Lefever as Assistant Secretary 
for Human Rights and Humanitarian Affairs; the President, at the 
nominee's request, then withdrew the nomination. In 1983, the committee 
reported unfavorably the nomination of Kenneth L. Adelman as Director 
of the Arms Control and Disarmament Agency, but the nomination was 
approved by the full Senate.
---------------------------------------------------------------------------
    Presidents have sometimes conferred the ``personal rank'' 
of ambassador on persons appointed without Senate approval in 
order for the person to have equal diplomatic standing with 
representatives of other nations. The first person to receive 
the personal rank of ambassador was Whitelaw Reid, sent by 
President McKinley in 1897 for the ceremonial occasion of the 
60th anniversary of Queen Victoria's accession to the throne. 
Later the practice was extended to negotiating occasions. After 
the First World War, for example, the Secretary of the American 
commission to negotiate peace was given the rank of minister 
plenipotentiary.\44\

    Congress has taken action to curb the practice of according 
persons the title of ambassador without the advice and consent 
of the Senate.\45\ In 1972, Congress incorporated into law a 
limitation that the President could confer the personal rank of 
ambassador or minister on an individual only in connection with 
a special mission for the President of a temporary nature and 
for a period not exceeding 6 months.\46\ The Foreign Service 
Act of 1980 also requires the President, except in urgent 
circumstances, 30 days prior to the conferral of the personal 
rank to submit a written report to the Foreign Relations 
Committee justifying the appointment.\47\

                D. Consultations During the Negotiations

    The earliest practice under the Constitution indicates that 
originally the Framers planned for the Senate to give advice to 
the President during the treatymaking process as well as to 
give or withhold consent to the final treaty,\48\ but this 
procedure soon ended. By the time President Polk referred the 
proposal to divide the Oregon Territory at the 49th parallel to 
the Senate for its advice prior to the signing of the Oregon 
Treaty of 1846, as well as for its consent afterward, it was a 
rare practice.\49\

Policy and the Separation of Powers. Cambridge, Harvard University 
Press, 1952. p. 49.
---------------------------------------------------------------------------
    As the process has evolved, the Senate as a whole does not 
give, and the President does not seek, its advice on a treaty 
until the end of the process when it is asked to give its 
advice and consent to ratification.
    Nevertheless, Presidents or their Secretaries of State have 
often consulted with individual Senators or committees prior to 
or during the negotiating process in order to enhance the 
prospects of the final treaty. Secretary of State Webster 
consulted frequently with important Senators about the Webster-
Ashburton Treaty of 1842 settling the Canadian-Maine 
boundary.\50\ With President Taylor a Whig and the Senate in 
control of the Democrats, Secretary of State Clayton consulted 
Senators of both parties over the Clayton-Bulwer Treaty of 1850 
concerning a canal in Central America. The practice has been 
continued intermittently throughout the 20th century.
---------------------------------------------------------------------------
    \50\ Cheever and Haviland, p. 48.
---------------------------------------------------------------------------
    The consultations can take many forms and can be initiated 
either by the Senate or the executive branch. The Senate 
Foreign Relations Committee or other committees may hold 
consultative meetings with executive branch officials on 
objectives and problems in treaties. Executive branch officials 
frequently discuss prospective treaties with individual 
Senators or committees, particularly the Senate Foreign 
Relations Committee because of its jurisdiction over treaties. 
Other methods of consultation include public oversight 
hearings, telephone discussions, letters, and contacts through 
staff members to exchange information and views on progress and 
problems in the negotiations.
    Sometimes the consultation is effective in the sense that 
congressional views help shape the final product. One of the 
best examples is the drafting of the U.N. Charter. On May 27, 
1942, the chairman of the Foreign Relations Committee Senator 
Tom Connally, and Senator Warren R. Austin, the minority member 
of the committee designated after consultation with Republican 
leaders, and later other Members of both houses of Congress, 
were invited to participate in an Advisory Committee on Postwar 
Foreign Policy that did much of the initial planning for the 
United Nations. By 1944 a bipartisan committee of eight Members 
was meeting weekly for this purpose. In the case of the North 
Atlantic Treaty the Senate Foreign Relations Committee was 
consulted frequently during the negotiations and suggested 
specific language in the text.\51\

    On occasion Congress has passed legislation requesting or 
requiring provision of information about negotiations. The 
International Development and Food Assistance Act of 1978 
required the Secretary of State to keep the Senate Foreign 
Relations and House Foreign Affairs and the Appropriations 
Committees ``fully and currently informed of any negotiations 
with any foreign government with respect to any cancellation, 
renegotiations, rescheduling, compromise, or other form of debt 
relief * * * with regard to any debt owed to the United States 
by any such foreign government,'' and to submit the texts of 
any agreement that would result in debt relief no less than 30 
days prior to its entry into force.\52\
---------------------------------------------------------------------------
    \52\ Sec. 603, Public Law 95-424, approved October 6, 1978.
---------------------------------------------------------------------------
    At other times legislation has required consultations on 
the negotiations. Since 1981, the International Financial 
Institutions Act has required the administration to consult 
with 16 specified Members of Congress (the chairmen and ranking 
minority members of the authorizing and appropriations 
committees and subcommittees having appropriate jurisdiction) 
prior to, during, and at the close of any international 
negotiations that might involve new U.S. contributions to the 
multilateral development banks.\53\
---------------------------------------------------------------------------
    \53\ Sec. 1201 of International Financial Institutions Act, Public 
Law 95-118, approved October 3, 1977.
---------------------------------------------------------------------------
    The Trade Act of 1974 provided that before the President 
enters into any trade agreement relating to nontariff barriers, 
he ``shall consult'' with the Committee on Ways and Means of 
the House, the Finance Committee of the Senate, and each 
committee or joint committee of Congress having jurisdiction 
over legislation involving subject matters affected by the 
agreement.\54\ The legislation made consultation mandatory by 
providing that any agreement could enter into force only if the 
President gave Congress 90 days prior notification and 
presented an implementing bill which was enacted into law.\55\ 
The Omnibus Trade and Competitiveness Act of 1988 revised 
``fast-track'' or expedited procedures for implementing trade 
legislation and required increased consultation with 
Congress.\56\

---------------------------------------------------------------------------
    Another category of Senate or congressional action might be 
considered ``consultation'': action critical of executive 
branch positions taken during or just after negotiations, with 
clear notice or the implication that the Senate will not 
favorably consider any treaty adopted with the offending 
provisions or effect remaining in the adopted treaty text. At 
least four recent examples can be identified. First, during the 
protracted negotiations that led to adoption of the 1982 United 
Nations Convention on the Law of the Sea, Congress considered 
legislation setting up a U.S. domestic regime for deep seabed 
hard mineral resource development. During Senate floor debate 
on these legislative proposals on December 14, 1979, several 
Senators identified the problems they found with the treaty 
provisions being negotiated and specifically characterized 
their statements as ``instructions'' to the executive branch, 
to be considered as ``advice'' under the Constitution's 
``advice and consent'' clause relating to treaties. Thereafter, 
Congress passed the Deep Seabed Hard Mineral Resources Act, 
which was signed by President Carter in June 1980 (Public Law 
96-283). President Reagan, in 1982, after reviewing the treaty 
texts, decided not to support its adoption. Later, in 1994, an 
agreement was adopted changing many of the objectionable 
convention provisions, and President Clinton transmitted the 
convention and agreement to the Senate (Treaty Doc. 103-39) 
where they remain, pending since 1994.\57\ The Senate thus 
expressed its views, and some in Congress, even many years 
afterward and with treaty amendments adopted, viewed the treaty 
as flawed.

---------------------------------------------------------------------------
    Senate and congressional actions after negotiation and 
adoption, in 1988, of the Convention on the Regulation of 
Antarctic Mineral Resource Activities show the way 
congressional expressions of disapproval of a just adopted and 
signed treaty led to the negotiation and adoption of a 
completely new treaty. Congress, by joint resolution, stated 
that the signed convention did not ``guarantee the protection'' 
of the Antarctic marine environment and ``could actually 
stimulate * * * commercial exploitation.'' Congress urged the 
executive branch to negotiate protocols or agreements that 
would provide ``comprehensive environmental protection of 
Antarctica'' and close the region to ``commercial minerals 
development * * * for an indefinite period.'' The resolution 
also stated that the President should not send the convention 
to the Senate before the environmental agreements were in 
force.\58\ On October 7, 1992, the Senate approved the Protocol 
on Environmental Protection to the Antarctic Treaty which had 
been signed a year earlier and sent to the Senate.\59\

    Another example of the Senate's expression of its views on 
the content of a treaty, both during negotiations and after its 
adoption and U.S. signature, is the Kyoto Protocol to the 
United Nations Framework Convention on Climate Change. Detailed 
information on this protocol, adopted in December 1997 and 
signed by the United States on November 12, 1998, is found in 
Chapter X, infra. In July 1997, before the protocol was 
adopted, the Senate had expressed its views on the treaty text 
in S. Res. 98. The protocol text did not meet the requirements 
set by the Senate resolution.
    A fourth example is the Statute of the International 
Criminal Court (ICC), adopted in Rome in July 1998 and signed 
on behalf of the United States on December 31, 2000. While some 
Senators expressed support for an ICC, others expressed 
concerns over the content of the statute while it was under 
negotiation and afterward. They worried that ICC actions could 
infringe on or diminish the rights of American citizens under 
the first and fourth amendments of the U.S. Constitution. 
During the 106th Congress, the Senate Foreign Relations 
Committee, in response to these concerns, added understandings 
to resolutions of advice and consent to ratification of U.S. 
treaties on mutual legal assistance in criminal matters and to 
extradition treaties. See Chapter X, infra, for further 
discussion.

            inclusion of members of congress on delegations

    On occasion Senators or Representatives have served as 
members of or advisers to the U.S. delegation negotiating a 
treaty. The practice has occurred throughout American history. 
In September 1898, President William McKinley appointed three 
Senators to a commission to negotiate a treaty with Spain. 
President Warren G. Harding appointed Senators Henry Cabot 
Lodge and Oscar Underwood as delegates to the Conference on the 
Limitation of Armaments in 1921 and 1922 which resulted in four 
treaties, and President Hoover appointed two Senators to the 
London Naval Arms Limitation Conference in 1930.
    The practice has increased since the end of the Second 
World War, in part because President Wilson's lack of inclusion 
of any Senators in the American delegation to the Paris Peace 
Conference was considered one of the reasons for the failure of 
the Versailles Treaty. Four of the eight members of the 
official U.S. delegation to the San Francisco Conference 
establishing the United Nations were Members of Congress: 
Senators Tom Connally and Arthur Vandenberg and Representatives 
Sol Bloom and Charles A. Eaton.
    There has been some controversy over active Members of 
Congress serving on such delegations. When President James 
Madison appointed Senator James A. Bayard and Speaker of the 
House Henry Clay to the commission that negotiated the Treaty 
of Ghent in 1814, both resigned from Congress to undertake the 
task. More recently, as in the annual appointment of Senators 
or Members of Congress to be among the U.S. representatives to 
the United Nations General Assembly, Members have participated 
in delegations without resigning, and many observers consider 
it ``now common practice and no longer challenged.'' \60\

    \60\ Henkin, Louis. Foreign Affairs and the Constitution. Mineola, 
N.Y. Foundation Press, 1972, p. 132.
---------------------------------------------------------------------------
    One issue has been whether service by a Member of Congress 
on a delegation violated Article I, Section 6 of the 
Constitution. This section prohibits Senators or 
Representatives during their terms from being appointed to a 
civil office if it has been created or its emoluments increased 
during their terms, and prohibits a person holding office to be 
a Member of the Senate or House. Some contend that membership 
on a negotiating delegation constitutes holding an office while 
others contend that because of its temporary nature it is not.
    Another issue concerns the separation of powers. One view 
is that as a member of a negotiating delegation a Senator would 
be subject to the instructions of the President and would face 
a conflict of interest when later required to vote on the 
treaty in the Senate. Others contend that congressional members 
of delegations may insist on their independence of action and 
that in any event upon resuming their legislative duties have a 
right and duty to act independently of the executive branch on 
matters concerning the treaty.
    A compromise solution has been to appoint Members of 
Congress as advisers or observers, rather than as members of 
the delegation. The administration has on numerous occasions 
invited one or more Senators and Members of Congress or 
congressional staff to serve as advisers to negotiations of 
multilateral treaties.\61\ In 1991 and 1992, for example, 
Members of Congress and congressional staff were included as 
advisers and observers in the U.S. delegations to the United 
Nations Conference on Environment and Development and its 
preparatory meetings. In 1992, congressional staff advisers 
were included in the delegations to the World Administrative 
Radio Conference (WARC) of the International Radio Consultative 
Committee (CCIR) of the International Telecommunications Union.
---------------------------------------------------------------------------
    \61\ The names of congressional advisers to international 
conferences before December 15, 1995 may be found in an annual list of 
U.S. accredited delegations that includes private sector 
representatives, published in the Federal Register in accordance with 
Article III(c)(5) of the guidelines (March 23, 1987). The last list was 
published in Federal Register, December 2, 1996, vol. 61, no. 232, pp. 
63892-63916. Publication of this list was discontinued after the 
preparing Office of International Conferences, Department of State, 
ceased receiving funding that enabled the Office to compile and file 
the report with the Federal Register.
---------------------------------------------------------------------------
    In the early 1990s, Congress took initiatives to assure 
congressional observers. The Senate and House each designated 
an observer group for strategic arms reductions talks with the 
Soviet Union that began in 1985 and culminated with the 
Strategic Arms Reduction Treaty (START) approved by the Senate 
on October 1, 1992. In 1991, the Senate established a Senate 
World Climate Convention Observer Group. As of late 2000, at 
least two ongoing groups of Senate observers existed:
          1. Senate National Security Working Group.--This is a 
        bipartisan group of Senators who ``act as official 
        observers to negotiations * * * on the reduction or 
        limitation of nuclear weapons, conventional weapons or 
        weapons of mass destruction; the reduction, limitation, 
        or control of missile defenses; or related export 
        controls.''
          2. Senate Observer Group on U.N. Climate Change 
        Negotiations.--This is a ``bipartisan group of 
        Senators, appointed by the Majority and Minority 
        Leaders'' to monitor ``the status of negotiations on 
        global climate change and report[ing] periodically to 
        the Senate * * *.'' \62\

                        E. Conclusion or Signing

    The conclusion of an international agreement, usually 
indicated by signing or initialing a document or by an exchange 
of notes, is the end of the negotiations process and indicates 
that the negotiators have agreed on the terms of the agreement. 
Like the negotiation, the conclusion or signing is done by the 
President or his representatives and is considered a function 
of the executive branch.
    On occasion, Members of Congress have been among the 
signatories of treaties. Among those signing the U.N. Charter 
for the United States were Senators Tom Connally and Arthur H. 
Vandenberg and Representatives Sol Bloom and Charles A. Eaton. 
Senators Alexander Wiley and John Sparkman signed the Peace 
Treaty with Japan on September 8, 1951, and Senators Arthur 
Vandenberg and Tom Connally and Representative Sol Bloom signed 
the Inter-American Treaty of Reciprocal Assistance on September 
2, 1947.
    Signing an international agreement may indicate a nation's 
consent to be bound if this is its intention. Under U.S. 
practice this would be the case only with executive agreements; 
treaties are required to go through the ratification process to 
be binding. Occasionally, one government may intend signing of 
an international agreement to indicate consent to be bound 
while another signs subject to ratification. This was the case 
with the Agreement on Friendship, Defense, and Cooperation 
between the United States and the Kingdom of Spain, signed July 
2, 1982. The Spanish representative signed the agreement 
subject to ratification by the Cortes Generale, the Spanish 
Parliament, while the U.S. representative signed the document 
as an executive agreement that did not require ratification.

          F. Renegotiation of a Treaty Following Senate Action

    One view is that the Senate, in effect, participates in the 
negotiation of a treaty when the Senate's consideration of a 
treaty leads to a renegotiation of articles in the treaty. At 
the turn of the century, Senator Henry Cabot Lodge took the 
position that the Senate's consideration of a treaty should be 
viewed as a stage in the negotiation, and that a Senate 
amendment to a treaty is a proposition ``offered at a later 
stage of the negotiation by the other part of the American 
treaty-making power in the only manner in which they could then 
be offered. * * *'' He continued:
          The treaty, so called, is therefore still inchoate, a 
        mere project for a treaty, until the consent of the 
        Senate has been given to it * * * the Senate can only 
        present its views to a foreign government by 
        formulating them in the shape of amendments, which the 
        foreign government may reject, or accept, or meet, with 
        counter propositions, but of which it has no more right 
        to complain, than it has to complain of the offer of 
        any germane proposition at any other stage of the 
        negotiation.\63\

A Fighting Frigate and Other Essays and Addresses. New York, Scribner's 
1902, pp. 222-224.

    Renegotiation of a treaty after Senate consideration is not 
frequent, and in the case of multilateral treaties is usually 
considered infeasible because of the number of countries 
involved and the problems in arriving at the original 
agreement. Nevertheless, on occasion treaties, particularly 
bilateral treaties, are renegotiated or negotiated further and 
amended by protocol as a result of Senate consideration.\64\
---------------------------------------------------------------------------
    \64\ See also discussion in Chapter VII, Resubmission of the Treaty 
or Submission of Protocol.
---------------------------------------------------------------------------
    To illustrate, after hearings by various congressional 
committees on the Panama Canal treaties signed by President 
Carter and General Torrijos on September 7, 1977, President 
Carter and General Torrijos met on October 14, 1977, and issued 
a statement of understanding clarifying U.S. rights under the 
Neutrality Treaty. A number of congressional delegations, 
including separate ones headed by Senators Robert Byrd, the 
Majority Leader of the Senate, Howard Baker, the Minority 
Leader, and John Sparkman, chairman of the Foreign Relations 
Committee, visited Panama and discussed possible modifications 
with United States and Panamanian officials. The Senate gave 
its advice and consent to ratification of the Neutrality Treaty 
subject to two amendments that incorporated the Carter-Torrijos 
statement of understanding into Articles IV and VI.\65\

reservation before approving a tax convention with the United

be negotiated to take care of the issue.\66\ In 1979 a protocol

reservations was submitted to and approved by the Senate.\67\

     G. Interim Between Signing and Entry Into Force; Provisional 
                              Application

    Although it has been signed, a bilateral treaty does not 
enter into force until the parties ratify it and exchange 
ratifications. A multilateral treaty does not enter into force 
until a specified number of parties deposit their 
ratifications. Between the signing and entry into force, there 
is an interim period in which governments are not yet legally 
bound, but they have tentatively agreed to a future course of 
action. In the United States, this includes those periods (1) 
from signing to submission to the Senate, (2) during Senate 
consideration, (3) from Senate approval to Presidential signing 
of the ratification, and (4) from the ratification to the 
exchange or deposit of ratifications and entry into force.
    During this interim period the treaty is not yet in effect, 
but under international law nations have an obligation not to 
do anything that would defeat the purpose of the treaty. The 
Vienna Convention states in Article 18:
          A state is obliged to refrain from acts which would 
        defeat the object and purpose of an international 
        agreement when: (a) it has signed the agreement or has 
        exchanged instruments constituting the agreement 
        subject to ratification, acceptance or approval, until 
        it shall have made its intention clear not to become a 
        party to the agreement; or (b) it has expressed its 
        consent to be bound by the agreement, pending the entry 
        into force of the agreement and provided that such 
        entry into force is not unduly delayed.

    Beyond this there is the question of taking measures during 
the interim period to begin to carry out the treaty, such as 
establishing a preparatory commission. Sometimes treaties 
themselves provide for their provisional application. The 
Vienna Convention states in Article 25:
          1. A treaty or a part of a treaty is applied 
        provisionally pending its entry into force if:
                  (a) the treaty itself so provides; or
                  (b) the negotiating States have in some other 
                manner so agreed.
          2. Unless the treaty otherwise provides or the 
        negotiating States have otherwise agreed, the 
        provisional application of a treaty or a part of a 
        treaty with respect to a State shall be terminated if 
        that State notifies the other States between which the 
        treaty is being applied provisionally of its intention 
        not to become a party to the treaty.

    In the United States, provisional application of a treaty 
may be subject to question especially if it gives temporary 
effect to a treaty prior to its receiving the advice and 
consent of the Senate. An agreement to apply a treaty 
provisionally is in essence an executive agreement to undertake 
temporarily what the treaty may call for permanently. It ``must 
normally rest on the President's own constitutional 
authority.'' \68\ According to the Department of State, the 
President may also make a unilateral policy decision, without 
reaching agreement with the other parties to apply the treaty 
provisionally, ``so long as the obligations undertaken are all 
within the competence of the President under U.S. law.'' \69\ 
The primary factor for determining the appropriateness of 
provisional application, in the State Department view, 
``relates to the immediate need to settle quickly matters in 
the interest of the United States which are within the 
President's domestic law competence.'' \70\

    An example of a treaty pending in the Senate that has been 
provisionally applied by executive agreement is the maritime 
boundary agreement between the United States and Cuba, signed 
December 16, 1977. Originally, an executive agreement, by 
exchange of notes on April 27, 1977, had established a modus 
vivendi on a provisional maritime boundary to serve during that 
year while negotiations were underway. The treaty signed on 
December 16, 1977, contained a provision that the parties agree 
to apply the terms of the agreement ``provisionally'' for a 
period of 2 years from January 1, 1978. According to the 
Department of State, ``this agreement constituted an executive 
agreement contained within the text of the treaty.'' \71\ The 
treaty was transmitted to the Senate on January 23, 1979, and 
debated in the Senate, but final action was not taken. The 
treaty is still pending in the committee. The provisional 
application was subsequently extended for additional periods, 
most recently by an exchange of notes of December 30, 1997 and 
March 30, 1998.\72\
---------------------------------------------------------------------------

further extension was not transmitted to Congress.
---------------------------------------------------------------------------
    The Senate Foreign Relations Committee raised questions 
concerning the provisional application in its hearings on the 
treaty. The Department of State said that in its judgment the 
President had authority to enter into provisional maritime 
boundary agreements, and cited as precedents a provisional 
boundary line between Alaska and Canada on October 20, 1899, 
and on the Stacking River on February 20, 1878.\73\

    If a treaty has been approved by the Senate but not yet 
ratified by the President, or if there has been consultation 
with the Senate, the provisional application of a treaty may 
not raise objections. In one instance the United States 
submitted a declaration of provisional application of the 1962 
International Coffee Agreement after the Senate gave its advice 
and consent but before the implementing legislation had been 
passed by Congress. The declaration indicated that the United 
States would not assume any obligations for which such 
legislation was necessary.\74\

---------------------------------------------------------------------------
    In another case the executive branch submitted a 
declaration of provisional application of the 1971 
International Wheat Agreement after consultation and consent by 
the Senate Foreign Relations Committee, and for the 1975 and 
1976 protocols before the Foreign Relations Committee completed 
action.
    The observance in practice of two agreements between the 
United States and the Soviet Union on strategic arms limitation 
that had either not been ratified or had expired has also 
raised the question of application of a treaty that was not in 
force. The SALT I Interim Agreement on Certain Measures with 
Respect to the Limitation of Strategic Offensive Arms, was 
authorized by Congress and entered into force on October 3, 
1973, for 5 years.
    The SALT II Treaty on the Limitation of Strategic Offensive 
Arms was signed by the United States on June 18, 1979, but 
Senate action on it was indefinitely postponed after the Soviet 
invasion of Afghanistan. The administration adopted the policy, 
as expressed by President Reagan on May 31, 1982, that ``As for 
existing strategic arms agreements, we will refrain from 
actions which undercut them so long as the Soviet Union shows 
equal restraint.'' The Senate Foreign Relations Committee 
reported a resolution (S.J. Res. 212) on July 12, 1982, which 
resolved that to provide a basis for progress during new 
negotiations, ``the United States shall continue to refrain 
from actions which would undercut the SALT I and SALT II 
agreements, provided the Soviet Union shows equal restraint.'' 
The committee reported that its purpose was to give the 
President's statement the full force and effect of law. The 
Subcommittee on Separation of Powers of the Senate Judiciary 
Committee held hearings on the resolution and urged its 
rejection on grounds, among others, that,
          In attempting to bind the United States to treaty 
        obligations without securing the approval of two-thirds 
        of the Senate, the resolution improperly limits the 
        President's negotiating powers in the area or foreign 
        affairs; it improperly attempts to transform a treaty 
        into some other form of international obligation; and 
        it improperly ignores the exclusive advice and consent 
        function of the Senate by making the obligation 
        dependent upon approval by the House of 
        Representatives.\75\

On October 12, 2000, the Senate, in passing S. Res. 267, 
returned the SALT II Treaty (Treaty Doc. 96-25) to the 
President, as part of a package of 17 treaties. This action had 
been recommended by the Senate Foreign Relations Committee.
    Another recent example of the use of provisional 
application is in the 1994 Agreement Relating to Implementation 
of Part XI of the 1982 United Nations Convention on the Law of 
the Sea. The agreement was adopted between the time the 1982 
convention was adopted and the time it entered into force 
(November 16, 1994). The agreement was applied provisionally 
between November 16, 1994, and July 28, 1996, when it entered 
into force. Thereafter, States that had not ratified the 
convention/agreement package by July 28, 1996, could continue 
membership in the International Seabed Authority, the 
international organization set up by the convention/agreement 
package until November 16, 1998. Negotiators, in 1994, 
considered this 4-year interval to be a time period sufficient 
to allow non-states parties to adhere to the package. On 
November 16, 1998, however, the United States and seven other 
countries that enjoyed provisional membership in the 
International Seabed Authority but had not yet ratified or 
adhered to the convention/agreement package lost that 
membership, becoming observer states.
    If the provisional application of a treaty became 
contentious, it would be up to the President or the Senate, 
depending on where the treaty resided at the time, to make 
clear either the intention to proceed with the ratification 
process and become a party, or the intention not to become a 
party.


                VI. SENATE CONSIDERATION OF TREATIES \1\
---------------------------------------------------------------------------

    \1\ Prepared by Stanley Bach, Senior Specialist in the Legislative 
Process and David M. Ackerman, Legislative Attorney. For additional 
information see: Riddick, Floyd M. and Alan S. Frumin, Riddick's Senate 
Procedure, Sen. Doc. 101-28, 1992, especially pp. 832-843 (``Executive 
Business and Executive Sessions'') and 1294-1310 (``Treaties'').
---------------------------------------------------------------------------
                              ----------                              

    The Constitution, in Article II, Section 2, Clause 2, 
provides that the President ``shall have Power, by and with the 
Advice and Consent of the Senate, to make Treaties, provided 
two-thirds of the Senators present concur.'' It is the 
President who negotiates and ultimately ratifies treaties for 
the United States, but only if the Senate in the intervening 
period gives its advice and consent. This chapter concerns the 
practices and procedures that the Senate follows after the 
President formally submits a treaty for the Senate's advice and 
consent.
    Whatever the authors of the Constitution may have meant by 
the phrase ``advice and consent'' with regard to treaties, it 
is generally used today to describe the process of Senate 
approval following Presidential transmission to the Senate of a 
fully negotiated and signed document. The ``Founding Fathers'' 
undoubtedly envisioned in their original conception of 
``treaty-making'' that the Senate would fulfill the role of 
collective advisor to the President in the initiation and 
conduct of negotiations. For reasons outlined earlier in this 
study, however, that type of advice now is rarely sought from 
the Senate. Consultations are not uncommon with respect to 
treaties on matters of major national importance, such as 
nuclear arms control, and Members of the Senate (and the House 
as well) frequently are appointed as advisors or observers to 
U.S. delegations. In addition, pursuant to the Case-Zablocki 
Act \2\ and the consultation procedures to which the State 
Department agreed in 1978,\3\ the Senate and the executive 
branch have taken steps toward increased notification to and 
consultation with the Senate with respect to executive branch 
negotiation and execution of international agreements and 
treaties.\4\ What Presidents generally seek from Senators, 
however, is not advice in advance but consent after the fact--
after negotiations have been completed. Most treaties engage 
the Senate only after their formal transmission by the 
President for approval. Nevertheless, the Senate often provides 
a measure of after-the-fact ``advice'' along with its 
``consent.''

---------------------------------------------------------------------------
    Contrary to past characterizations of the Senate as the 
``graveyard of treaties,'' the overwhelming majority of 
treaties receive favorable Senate action within a reasonable 
period of time. Few treaties languish indefinitely or are 
returned to the President without approval, and even fewer are 
defeated outright by vote of the Senate. Likewise, most 
treaties survive the process of advice and consent without 
material change, although the Senate in recent years has 
expanded its use of conditions that are attached to its 
resolutions of ratification. In most cases, the process of 
Senate consideration is expedited, without using the full 
procedures available under Senate rules, and Senate approval 
frequently is unanimous. However, the most controversial and 
important treaties can receive extended consideration, in 
committee and on the Senate floor, during which numerous 
amendments and conditions may be proposed.

                     A. Senate Receipt and Referral

    All treaties are transmitted to the Senate in the 
President's name, a procedure that typically first involves 
formal submission of the agreement to the President by the 
Secretary of State and may include a separate review of the 
agreement by the White House staff. Therefore, the time period 
between signature of a treaty and its actual transmission to 
the Senate for advice and consent may be considerable, as much 
for bureaucratic as for substantive or political reasons. But 
the President controls the timing of a treaty's submission. 
Occasionally an administration may decide not to submit a 
treaty that it or a previous administration had signed.
    The Senate receives a Presidential message consisting of 
the official title and text of the treaty (the original in the 
case of a bilateral treaty, a certified copy in the case of a 
multilateral one) and a letter of transmittal, signed by the 
President, requesting Senate advice and consent and 
incorporating the earlier Letter of Submittal from the 
Secretary of State to the President. The Secretary's letter 
usually contains a detailed description and analysis of the 
treaty. The Presidential message also may contain protocols, 
annexes, or other documents that the President submits to the 
Senate to be considered as integral parts of the proposed 
treaty (as distinguished from documents submitted for 
information purposes only). They are referred to collectively 
as the treaty and its official papers. These documents, which 
have been submitted to the Senate for advice and consent to 
ratification as integral parts of a treaty, are subject to a 
single vote of advice and consent. For the same reason, only a 
treaty and its official papers, when formally before the 
Senate, are subject to amendment.
    If the executive branch concludes a protocol amending a 
treaty that is pending in the Senate, the protocol is submitted 
to the Senate as a new treaty. The Senate may decide, however, 
to consider the treaty and protocol together and approve them 
by means of a single resolution of ratification.\5\

Amending Protocols: Selected Precedents.

                            senate rule xxx

    Senate Rule XXX governs the process of treaty consideration 
in the Senate. As revised on February 27, 1986, Rule XXX states 
\6\:
---------------------------------------------------------------------------
    \6\ The Senate's standing rules were revised and renumbered in 
1980, which can lead to difficulties when references are made to 
earlier publications. In addition, S. Res. 28, adopted on February 27, 
1986, made a significant change in Rule XXX. Previously, the rule 
provided for a first stage of floor consideration, during which the 
Senate would meet ``as in Committee of the Whole'' and act on any 
proposed amendments to each article of the treaty in sequence. Although 
the full procedures of Rule XXX rarely were invoked, they were followed 
during Senate consideration of the Versailles Peace Treaty following 
World War I, the Panama Canal Treaties in 1978, and the Genocide 
Convention in 1986. Citations to Senate rules are to the publication

Document 106-15.
---------------------------------------------------------------------------

               executive session--proceedings on treaties

          1. (a) When a treaty shall be laid before the Senate 
        for ratification, it shall be read a first time; and no 
        motion in respect to it shall be in order, except to 
        refer it to a committee, to print it in confidence for 
        the use of the Senate, or to remove the injunction of 
        secrecy.
          (b) When a treaty is reported from a committee with 
        or without amendment, it shall, unless the Senate 
        unanimously otherwise directs, lie over one day for 
        consideration; after which it may be read a second 
        time, after which amendments may be proposed. At any 
        stage of such proceedings the Senate may remove the 
        injunction of secrecy from the treaty.
          (c) The decisions thus made shall be reduced to the 
        form of a resolution of ratification, with or without 
        amendments, as the case may be, which shall be proposed 
        on a subsequent day, unless, by unanimous consent, the 
        Senate determines otherwise, at which stage no 
        amendment to the treaty shall be received unless by 
        unanimous consent; but the resolution of ratification 
        when pending shall be open to amendment in the form of 
        reservations, declarations, statements, or 
        understandings.
          (d) On the final question to advise and consent to 
        the ratification in the form agreed to, the concurrence 
        of two-thirds of the Senators present shall be 
        necessary to determine it in the affirmative; but all 
        other motions and questions upon a treaty shall be 
        decided by a majority vote, except a motion to postpone 
        indefinitely, which shall be decided by a vote of two-
        thirds.
          2. Treaties transmitted by the President to the 
        Senate for ratification shall be resumed at the second 
        or any subsequent session of the same Congress at the 
        stage in which they were left at the final adjournment 
        of the session at which they were transmitted; but all 
        proceedings on treaties shall terminate with the 
        Congress, and they shall be resumed at the commencement 
        of the next Congress as if no proceedings had 
        previously been had thereon.

             action on receipt of treaty from the president

    When a treaty message is received from the President, it is 
transmitted by the Senate Parliamentarian to the Executive 
Clerk, who is responsible for treaties and nominations. The 
Executive Clerk assigns it a message number and prepares a 
procedural request for unanimous consent to remove the 
injunction of secrecy referred to in Senate Rules XXIX and 
XXX.\7\ (This injunction originated during the days when Senate 
executive sessions were conducted in secret. Treaties today are 
normally made public when signed or even earlier.) Ordinarily, 
the Senate routinely agrees to the Majority Leader's request to 
remove the injunction of secrecy. If any Senator should object 
to the request, the full Senate can agree to a resolution 
removing the injunction of secrecy, as provided in Senate Rule 
XXIX. On at least one recent occasion, such an objection was 
used to throw a temporary procedural roadblock in the way of 
Senate consideration of a tax treaty.\8\
---------------------------------------------------------------------------
    \7\ Paragraph 3 of Rule XXIX provides that ``All confidential 
communications made by the President of the United States to the Senate 
shall be by the Senators and the officers of the Senate kept secret; 
and all treaties which may be laid before the Senate, and all remarks, 
votes, and proceedings thereon shall also be kept secret, until the 
Senate shall, by their resolution, take off the injunction of 
secrecy.''
    \8\ On July 21, 1980, Senator Mike Gravel of Alaska objected to a 
unanimous consent request to remove the injunction of secrecy from a 
revised income tax convention with Israel.
---------------------------------------------------------------------------
    Since Senate consideration of treaties is a matter of 
executive business, the Senate must be in executive session \9\ 
in order to remove the injunction of secrecy or take any other 
floor action with respect to a treaty. The motion to go into 
executive session is non-amendable and non-debatable but is 
subject to a request for a roll call vote. Normally, however, 
the Senate moves between executive and legislative session by 
unanimous consent.
---------------------------------------------------------------------------
    \9\ The Senate meets in legislative session to transact its 
legislative business. The consideration of treaties and nominations, on 
the other hand, constitutes the Senate's executive business and takes 
place in executive session. By unanimous consent, the Senate sometimes 
transacts some executive business without first resolving into 
executive session. On January 3, 2001, the first day of the 107th 
Congress, for example, the Senate agreed to a unanimous consent request 
that, ``for the duration of the 107th Congress, it shall be in order to 
refer [to committee] treaties and nominations on the day when they are 
received from the President, even when the Senate has no executive 
session that day.'' Congressional Record, January 3, 2001, p. S8 (daily 
ed.).
---------------------------------------------------------------------------
    The request of the Majority Leader is typically in the 
following form:
          I ask unanimous consent that the injunction of 
        secrecy be removed from the Third Protocol to the 1975 
        Tax Convention with the United Kingdom of Great Britain 
        and Northern Ireland, as amended, signed at London on 
        March 15, 1979 (Executive Q, 96th Cong., 1st Sess.), 
        transmitted to the Senate by the President of the 
        United States on April 12, 1979.
          I ask that the treaty be considered as having been 
        read the first time, that it be referred to the 
        Committee on Foreign Relations and ordered to be 
        printed, and that the President's message be printed in 
        the Record.
          The PRESIDING OFFICER. Without objection, it is so 
        ordered.\10\

Procedure. Sen. Doc. 101-28, 1992, p. 1300.

    Following the first reading and removal of the injunction 
of secrecy at the initiative of the Majority Leader, the 
Presiding Officer refers the treaty to the Committee on Foreign 
Relations, in accordance with Senate Rule XXV on the 
jurisdiction of standing committees. At this stage, the text of 
the President's message, the treaty, all documents submitted as 
integral parts of the treaty, and any other documents submitted 
for the information of the Senate, are printed by the U.S. 
Government Printing Office and made available online to the 
public.\11\
---------------------------------------------------------------------------
    \11\ Information may be found online at http://www.access.gpo.gov/
congress/doccat.html.
---------------------------------------------------------------------------
    Treaties are referred to committee after being read once, 
whereas bills and joint resolutions must, in principle, go 
through a second reading (a subsequent procedural step) before 
they are eligible for referral.
    Thereafter, each treaty is referred to by its Treaty 
Document Number, which consists of the number of the Congress 
in which it was transmitted, followed by a number representing 
the order in which treaties were submitted in that Congress, 
for example, Treaty Doc. 97-1 or 106-13. Before the 97th 
Congress in 1981, a letter designation was used rather than 
consecutive numbering (for example, Executive Q in the example 
quoted above). Treaties that were transmitted before that time 
and that, for one reason or another, have not been acted upon 
by the Senate retain their original designation. The 
International Labor Organization Convention No. 87 Concerning 
Freedom of Association and Protection of the Right to Organize, 
for example, which was originally transmitted by President 
Truman in 1949, is designated Ex. S, 81-1, for Eighty-first 
Congress, First Session.
    Since its creation in 1816, the Foreign Relations Committee 
has had exclusive jurisdiction over treaties, as presently 
recognized in Rule XXV.\12\ From time to time other Senate 
committees have sought referral of particular treaties, but 
without success. There have been various occasions, however, on 
which other committees have conducted hearings on the issues 
raised by particular treaties even though those committees did 
not have authority to make formal recommendations to the Senate 
regarding the treaties.
---------------------------------------------------------------------------
    \12\ Senate Rule XXV(l)(j)(1)17 states the Committee on Foreign 
Relations has jurisdiction over ``Treaties and executive agreements, 
except reciprocal trade agreements.'' Rule XXV(l)(i)7 states the 
Committee on Finance has jurisdiction over ``Reciprocal trade 
agreements.''
---------------------------------------------------------------------------
    In the case of the Treaty Between the United States of 
America and the Union of Soviet Socialist Republics on the 
Limitation of Strategic Offensive Arms and the Protocol 
Thereto,\13\ commonly known as SALT II, for example, the 
Committee on Armed Services held extensive hearings on the 
military implications of the treaty,\14\ similar to the 
parallel hearings it held in 1963 on the Nuclear Test Ban 
Treaty, in 1969 on the Nuclear Non-Proliferation Treaty, and in 
1978 on the Panama Canal Treaties. The Armed Services Committee 
even took a vote on the SALT II Treaty and prepared an 
extensive report in opposition to Senate approval.\15\ In the 
cases of the Treaty on the Elimination of Intermediate-Range 
and Shorter-Range Missiles (INF), the Conventional Armed Forces 
in Europe Treaty (CFE), the Treaty on the Reduction and 
Limitation of Strategic Offensive Arms (START), and the Open 
Skies Treaty, the Armed Services and Intelligence Committees 
reported their findings to the Senate Foreign Relations 
Committee during that committee's consideration of the 
treaties, and the other committees' recommendations were 
included in the reports of the Committee on Foreign 
Relations.\16\ More recently, the Armed Services Committee 
received testimony in 1995 on the national security 
implications of U.S. ratification of the START II Treaty before 
the Foreign Relations Committee reported that treaty to the 
Senate. Similarly, the Armed Services Committee received 
testimony on several occasions in 1997 and 1998 on North 
Atlantic Treaty Organization (NATO) expansion, both before and 
after the Foreign Relations Committee completed action on a 
treaty on that subject.\17\

    Other Senate and House committees have occasionally 
prepared reports on treaties of particular concern to them. 
Sometimes the Foreign Relations Committee has invited members 
of other committees to participate in its hearings relating to 
treaties, such as the SALT II Treaty, of obvious interest to 
such committees.

              B. Foreign Relations Committee Consideration

    Once referred to the Foreign Relations Committee, each 
treaty is placed on the committee calendar, in a separate 
treaty section and arranged chronologically in order of 
referral date. Committee Rule 9 governs the committee's 
consideration of treaties. It states:
          (a) The Committee is the only committee of the Senate 
        with jurisdiction to review and report to the Senate on 
        treaties submitted by the President for Senate advice 
        and consent. Because the House of Representatives has 
        no role in the approval of treaties, the Committee is 
        therefore the only congressional committee with 
        responsibility for treaties.
          (b) Once submitted by the President for advice and 
        consent, each treaty is referred to the Committee and 
        remains on its calendar from Congress to Congress until 
        the Committee takes action to report it to the Senate 
        or recommend its return to the President, or until the 
        Committee is discharged of the treaty by the Senate.
          (c) In accordance with Senate Rule XXX.2, treaties 
        which have been reported to the Senate but not acted on 
        before the end of a Congress ``shall be resumed at the 
        commencement of the next Congress as if no proceedings 
        had previously been had thereon.''
          (d) Insofar as possible, the Committee should conduct 
        a public hearing on each treaty as soon as possible 
        after its submission by the President. Except in 
        extraordinary circumstances, treaties reported to the 
        Senate shall be accompanied by a written report.\18\

    The decision to hold hearings or take other action on 
particular treaties ordinarily is made by the committee 
chairman, in consultation with the ranking minority member. The 
chairman's decisions in this regard are influenced to an 
important degree by the preferences of the executive branch. At 
the beginning of each Congress, the committee routinely 
requests from the Department of State a written ranking of its 
treaty priorities, which is normally conveyed in several 
general groupings. Although such requests have no formal status 
or procedural consequences, the committee usually gives great 
weight to them in planning its schedule. Such decisions also 
are affected by the overall priorities and time constraints of 
the chairman and other committee members.
    Committee hearings on treaties principally involve 
executive branch, usually State Department, witnesses. Since 
most treaties are noncontroversial, the objective is to develop 
a record explaining the purposes, provisions, and significance 
of the agreement. When a treaty is controversial or 
complicated, however, the hearing process can be extensive, 
involving many witnesses and days of questioning and 
deliberations. Extensive hearings in recent years have included 
those in 1977-1978 on the Panama Canal Treaties, in 1979 on the 
SALT II Treaty, in 1988 on the INF Treaty, and in 1991-1992 on 
the START Treaty. More recently, the committee held hearings on 
the Chemical Weapons Convention on a total of 14 days.
    The chairman of the Foreign Relations Committee generally 
decides on the timing for committee markup of treaties, which 
normally comes soon after the completion of hearings. The 
predominant tendency is for the committee to recommend Senate 
advice and consent without numerous conditions, and the 
committee usually votes on treaties without extended debate or 
discussion. In the case of a controversial treaty, however, or 
when it is clear that particular problems must be resolved to 
assure Senate approval, the chairman may initiate proposals for 
conditions or other specific language to address those 
problems. The types of conditions available are discussed in 
the following section. Whether or not the committee does decide 
to recommend Senate conditions, when it reports out the treaty 
the committee also proposes a ``resolution of ratification,'' 
usually in the following form:
          Resolved, (two-thirds of the Senators present 
        concurring, therein), That the Senate advise and 
        consent to the ratification of [or accession to] the 
        [official treaty title].

    Generally, treaties are considered within a year of their 
transmission, after allowing sufficient time for public notice 
and comment. From time to time, however, the press of other 
business has resulted in backlogs of unreported treaties. 
Particular treaties may languish on the committee's calendar, 
not necessarily because of serious opposition but for want of 
interested advocates with the time to do justice to them. In 
other cases, treaties have been shepherded through with 
dispatch, owing to their importance and timeliness or to the 
interest of the chairman or particular members of the 
committee. Groups of similar treaties frequently have been 
considered en bloc, both in committee and on the Senate floor, 
thereby facilitating comparison and reducing the demands on 
Senators' time.
    If the chairman does expect opposition or difficulty in 
gaining Senate approval of a particular treaty, his decision on 
the nature and timing of committee action becomes more 
problematic. Furthermore, unless the President is clearly in 
support of ratification (and a successor President may not 
always support all treaties submitted prior to his taking 
office), Senate action may be pointless, since the President 
can simply decline to ratify a treaty even after Senate 
approval.
    All treaties remain on the committee's calendar until the 
committee takes action on them. In accordance with Senate Rule 
XXX, paragraph 2, all treaties reported by the committee that 
are not thereafter disposed of by the Senate (either by 
favorable advice and consent or by formal return to the 
President) rest on the Executive Calendar and then, at the end 
of the Congress, automatically are returned, or re-referred, to 
the committee. The committee must then report those treaties 
again during a subsequent Congress if they are to be considered 
on the Senate floor.
    As a consequence, the calendar of the Foreign Relations 
Committee contains some treaties that were transmitted years 
earlier and never finally disposed of by the Senate. The 
Genocide Convention, for instance, remained on the committee 
calendar from 1949 until 1986, when the Senate finally gave its 
advice and consent to ratification; by that time the committee 
had reported the convention favorably five times. In 1996 the 
committee reported the Chemical Weapons Convention that had 
been referred to it in 1993. The Senate debated but did not 
take final action on the convention in 1996, so it was re-
referred to the committee at the end of the 104th Congress. 
During the following year, the committee held additional 
hearings on the convention. The Senate then considered it 
again, after discharging the committee from its further 
consideration, and ultimately consented to its ratification.
    The workload of the committee and the Senate regarding 
treaties varies from Congress to Congress. In the past four 
Congresses, for example, the number of treaties to which the 
Senate gave its advice and consent grew from 27 in the 103d 
Congress (1993-1994) to 37 in the 104th (1995-1996) to 52 in 
each of the 105th (1997-1998) and 106th (1999-2000) 
Congresses.\19\
---------------------------------------------------------------------------
    \19\ See Appendix 8 for a list of all treaties to which the Senate 
gave its advice and consent to ratification during the 100th-106th 
Congresses. During this period, the chairmen of the committee have been 
Claiborne Pell of Rhode Island (100th-103d Congresses) and Jesse Helms 
of North Carolina (104th-106th Congresses).
---------------------------------------------------------------------------

                        C. Conditional Approval

    The Foreign Relations Committee may recommend that the 
Senate approve treaties conditionally, granting its advice and 
consent only subject to certain stipulations that the President 
must accept before proceeding to ratification.\20\ The 
President, of course, also may propose, at the time of a 
treaty's transmission to the Senate or during the Senate's 
consideration of it, that the Senate attach certain conditions 
or stipulations in the course of giving its advice and consent.

Relations Law of the United States. American Law Institute Publishers,

SALT II, the Foreign Relations Committee gave considerable attention to 
the nature and legal effect of Senate conditions and discussed the 
matter extensively in its report on the treaty. See S. Exec. Rept. 96-
14, 96th Cong., 1st Sess. (Nov. 19, 1979). An earlier discussion of

---------------------------------------------------------------------------

                          types of conditions

    Conditions traditionally have been categorized as 
amendments, reservations, understandings, declarations, and 
provisos. Whatever they are called, however, conditions 
generally are binding on the President, and the President 
cannot proceed to ratify a treaty without giving them effect. 
Because not all conditions necessarily affect the substance of 
a treaty, not all are necessarily communicated to the other 
party or parties to an agreement. But whatever name the Senate 
gives to a condition, if the President considers that it alters 
an international obligation under a treaty, he is expected to 
transmit it to the other party or parties. The result may be 
further negotiations or even abandonment of the treaty.
    Both amendments and reservations are proposed revisions in 
the obligations undertaken by the United States pursuant to a 
treaty. Amendments are proposed changes in the actual text of 
the treaty; reservations are specific qualifications or 
stipulations that modify U.S. obligations without necessarily 
changing treaty language.\21\ Both types of revisions amount, 
therefore, to Senate counter offers that alter the original 
deal agreed to by the United States and the other country or 
countries involved. In the case of treaties that represent 
significant trade-offs and compromises, such conditions 
normally require the re-opening of negotiations, assuming the 
other parties are willing to do so. In less delicate 
circumstances, or on secondary issues, such conditions may be 
accepted without extended delay, although that prospect is not 
always easy to evaluate during Senate committee or floor 
deliberations.
---------------------------------------------------------------------------
    \21\ The Vienna Convention on the Law of Treaties, which the U.S. 
has not ratified but which is viewed as codifying customary 
international law in most respects, defines ``reservation'' as follows:
    ``[R]eservation'' means a unilateral statement, however phrased or 
named, made by a State, when signing, ratifying, accepting, approving, 
or acceding to a treaty, whereby it purports to exclude or to modify 
the legal effect of certain provisions of the treaty in their 
application to that State. Vienna Convention, Article 2.
---------------------------------------------------------------------------
    In the case of large, multilateral agreements, amendments 
seldom are realistic; the difficulties in reconvening 
negotiations mean that significant amendments are normally 
taken by the other parties as tantamount to rejection of the 
treaty itself. Reservations on important provisions of the 
treaty can have the same result.
    The Foreign Relations Committee has repeatedly expressed 
concern with the inclusion of a provision in some multilateral 
treaties stating that no reservations may be made. In the 
committee's view, such a provision has the effect of preventing 
the Senate from exercising its constitutional duty to give 
advice and consent to a treaty, and the committee has asserted 
that its approval of a treaty containing such a provision 
should not be construed as a precedent.\22\
---------------------------------------------------------------------------
    \22\ See, for example, the United Nations Framework Convention on 
Climate Change, Exec. Rept. 102-55 to accompany Treaty Doc. 102-38. 
October 1, 1992, p. 15; and the Protocol on Environmental Protection to 
the Antarctic Treaty, Exec. Rept. 102-54, to accompany Treaty Doc. 102-
22. September 22, 1992. More recently, the Senate has begun to 
incorporate such statements in its resolutions of ratification as well 
as in its reports on treaties containing ``no-reservations'' clauses. 
See, for example, the Convention on Protection of Children and 
Cooperation in Respect of Intercountry Adoption, Exec. Rept. 106-14 to 
accompany Treaty Doc. 105-51. April 27, 2000, p. 11; and 146 
Congressional Record, September 20, 2000, p. S8867 (daily ed.). For 
further discussion of this point, see infra Chapter IX.
---------------------------------------------------------------------------
    In the case of bilateral treaties, there is little 
substantive difference between amendments and reservations, 
although there may be a significant diplomatic difference. (As 
discussed below, there also is a procedural difference in the 
Senate's consideration of amendments and reservations under 
Senate Rule XXX.) While it may be politically easier for the 
other country involved to accept a reservation rather than a 
change in the actual language of the treaty text, the legal 
effect is substantively the same: either form of condition 
amounts to a counter offer.
    Understandings, by contrast, are interpretive statements 
that clarify or elaborate, rather than change, the provisions 
of an agreement and that are deemed to be consistent with the 
obligations imposed by the agreement. The actual effect of any 
particular proposed understanding may, of course, be debatable. 
What may seem to the Senate to be a reasonable interpretation, 
and therefore an understanding, might appear to the other 
country or countries involved to be an important modification, 
and therefore a reservation, particularly if it concerns an 
aspect of the agreement that is considered fundamental. If that 
is the conclusion of another party to a treaty, the mere 
characterization of a condition as an understanding rather than 
a reservation will do little to change that conclusion. True 
understandings are commonly used in the ratification of both 
multilateral and bilateral treaties as a means of clarification 
and reassurance rather than revision.
    Declarations are statements of purpose, policy, or position 
related to matters raised by the treaty in question but not 
altering or limiting any of its provisions. The President has 
on occasion interpreted such declarations as falling outside of 
the formal provisions to be incorporated in the instruments 
used in the ratification process,\23\ and the Senate itself has 
at times so directed.\24\ As a consequence, such statements are 
often placed in a separate section of the Senate's resolution 
of ratification. The term ``declaration'' sometimes is used 
interchangeably with the term ``proviso.''
---------------------------------------------------------------------------
    \23\ In the case of the 1976 Treaty of Friendship and Cooperation 
with Spain, the State Department decided that it was inappropriate to 
include the text of a lengthy Senate declaration in the instruments of 
ratification, because the declaration related in part to the 
encouragement of ``free institutions'' in a ``democratic Spain'' and 
was certain to be offensive to Spain. The Department defended its 
position on this point in a memorandum that appears in the 1976 Digest 
of United States Practice in International Law. Eleanor C. McDowell 
ed., State Department pub. 8908, November 1977, pp. 215-217. A number 
of Senators protested however; and ultimately the declaration was 
included as a separate ``annex'' to the U.S. instrument of 
ratification.

``Inter-American Convention on Serving Criminal Sentences Abroad,'' 146 
Congressional Record, October 18, 2000, p. S10658 (daily ed.).
---------------------------------------------------------------------------
    Provisos often include conditions relating to the process 
of implementing a treaty within the United States. Among the 
conditions attached to the Senate's resolution of ratification 
of the Convention Against Torture and Other Cruel, Inhuman or 
Degrading Treatment or Punishment, for example, was a proviso, 
specifically not to be included in the instrument of 
ratification, that the President of the United States would not 
deposit the instrument of ratification until such time as he 
had notified all parties that nothing in the convention 
required or authorized legislation, or other action, by the 
United States prohibited by the Constitution as interpreted by 
the United States.\25\

    The Senate Committee on Foreign Relations gave considerable 
attention to the types of conditions added to treaties and to 
their legal effect during its consideration of the SALT II 
Treaty in 1979.\26\ The committee included a number of 
declarations, understandings, and reservations in the 
resolution of ratification it recommended to the Senate. But, 
concerned that the traditional labels left some ambiguity 
regarding the legal effect of the proposed conditions, it 
grouped them into the following three categories:
---------------------------------------------------------------------------
    \26\ The committee's concern had been stimulated in part by the 
administration's refusal in 1976 to include a Senate declaration in the 
instruments of ratification of a Treaty of Friendship and Cooperation 
with Spain. See n. 22. In addition, during hearings on the SALT II 
Treaty, former Yale Law School Dean Eugene V. Rostow had expressed the 
view that reservations did not have the same legal effect as amendments 
to the treaty itself. A reservation, he argued, ``has the same effect 
as a letter from my mother.'' Testimony of Eugene Rostow, chairman,

Foreign Relations Committee, July 19, 1979, in the SALT II Treaty,

Cong., 1st Sess., Part 2, p. 393, and subsequently repeated on 
September 6, 1979, Part 4, p. 13.
---------------------------------------------------------------------------
          (I) conditions that did not need to be formally 
        communicated to, or accepted by, the Soviet Union;
          (II) conditions that did need to be formally 
        communicated to, but not necessarily accepted by, the 
        Soviet Union; and
          (III) conditions that required the explicit agreement 
        of the Soviet Union.\27\

    In addition, the committee obtained the prior agreement of 
the administration to this format. Secretary of State Cyrus 
Vance gave assurances to the committee that
          (1) all conditions would be deemed equally binding on 
        the President regardless of the category in which they 
        were placed;
          (2) category II conditions would be conveyed to the 
        Soviet Union by formal diplomatic note prior to the 
        exchange of the instruments of ratification, thus 
        assuring that the Soviet Union understood the U.S. 
        position in advance of the treaty's entry into force, 
        yet not requiring explicit Soviet approval as in the 
        case of a condition conveyed in the instrument of 
        ratification; and
          (3) the executive branch would follow a procedure for 
        securing Soviet agreement to the provisions in category 
        III that would leave no doubt as to the explicit 
        agreement of the Soviet Union. This would probably be 
        done, the Secretary said, by securing explicit Soviet 
        agreement in the ``Protocol of Exchange of Instruments 
        of Ratification'' that is signed by both parties.\28\
---------------------------------------------------------------------------
    \28\ Id., at 29-32 (exchange of letters between the committee and 
the Secretary of State).

    Because of the Soviet Union's intervention in Afghanistan, 
the Senate never voted on the SALT II Resolution of 
Ratification. But it subsequently used these categories in its 
Resolution of Ratification on the INF Treaty. As noted, these 
categories, when used, have supplemented, not replaced, the 
traditional typology.
    The Committee on Foreign Relations re-emphasized its view 
regarding conditions in its 1985 report on the Genocide 
Convention, asserting that all conditions placed by the Senate 
on its advice and consent were to be included in the instrument 
of ratification unless the Senate expressly stated otherwise. 
The report said:
          Unless there is an express statement by the Senate to 
        the contrary, it is the Committee's firm view that all 
        conditions adopted by the Senate are to be included in 
        the instrument of ratification and therefore furnished 
        to all other parties to the treaty. Not only does the 
        Committee believe this to be the law, but it believes 
        it to be essential for practical reasons as well. The 
        Senate's conditions, together with the treaty and its 
        accompanying documents, describe in full the obligation 
        undertaken by the United States in ratifying the 
        treaty. To insure an identity of expectations by all 
        parties concerning the rights and obligations imposed 
        by the treaty, each party should be accorded formal 
        notice of the Senate's conditions. Notification by any 
        method other than inclusion in the instrument of 
        ratification simply increases the possibility of 
        misunderstanding.\29\

    More recently, the committee has adopted the practice of 
specifying which conditions are to be included in the 
instrument of ratification and which should not be included. It 
also has specified that particular declarations in its 
resolutions of ratification are binding on the President.\30\

               condition regarding treaty interpretation

    In the mid-1980s a controversy erupted that has resulted in 
the inclusion of a condition regarding treaty interpretation in 
every resolution of ratification adopted by the Senate. In the 
early 1980s the Reagan Administration initiated a ``Strategic 
Defense Initiative'' (SDI) to develop new means, including 
mobile- and space-based means, of protecting the United States 
against missile attack. Critics immediately charged that SDI 
would violate the 1972 Anti-Ballistic Missile (ABM) Treaty, 
which barred the United States and the Soviet Union from 
deploying ABM systems (except for one fixed site to protect 
either the nation's capital or an offensive missile complex) 
and from developing, testing, or deploying ``ABM systems which 
are sea-based, air-based, space-based, or mobile land-based.'' 
The administration responded that a broader interpretation of 
the treaty allowed the development and testing of ABM systems 
based on different physical principles than those that existed 
in 1972. It said that the text of the treaty was ``ambiguous'' 
in this respect, that the negotiating record of the treaty 
supported the broader interpretation, that the subsequent 
practice of the parties was consistent with the broader 
interpretation, and that as a consequence the President was 
justified in reinterpreting the treaty to more accurately 
reflect what the negotiating record said it meant.\31\
---------------------------------------------------------------------------
    \31\ For exposition of the administration's legal justifications, 
see Sofaer, Abraham, ``The ABM Treaty and the Strategic Defense 
Initiative,'' 99 Harvard Law Review 1972 (1986) and the testimonies of 
Abraham Sofaer, Legal Adviser to the State Department, and Richard 
Perle, Assistant Secretary of Defense for International Security 
Policy, Joint Hearings on the ABM Treaty and the Constitution Before 
the Senate Committee on Foreign Relations and the Senate Committee on 
the Judiciary (1987), at 119-170 and 351-375.
---------------------------------------------------------------------------
    Usually when the Foreign Relations Committee and the Senate 
consider a treaty, they do not have access to the full 
negotiating record, including all the instructions, 
transcripts, correspondence, and other often voluminous 
material relating to it. Instead, they rely on the testimony 
and other formal communications from the executive branch to 
ascertain a treaty's meaning. But in response to the 
administration's claims regarding the ABM Treaty, the Senate, 
at the initiative of Senators Nunn and Levin, sought and gained 
access to the negotiating record of the ABM Treaty.\32\ The 
Foreign Relations Committee and the Judiciary Committee held 
extensive hearings \33\; and Senator Biden submitted, and the 
Foreign Relations Committee reported, a resolution to constrain 
the administration's ability to reinterpret the ABM Treaty.\34\
---------------------------------------------------------------------------
    \32\ Under an access agreement concluded in February, 1988, the 
State Department supplied the documents, and the Senate created an Arms 
Control Treaty Review Support Office to house and provide a system for 
using the documents. After extended study, Senator Nunn, in detailed 
commentaries on the Senate floor, asserted that this record as well as 
the Senate's ratification hearings and debates and the subsequent 
practices of the parties belied the administration's claim. See 133 
Congressional Record 5296-5302 (March 11, 1987), 5582-5587 (March 12, 
1987), 5688-5690 (March 13, 1987), and 13143-13163 (May 20, 1987).

Interpretation Resolution,'' and S. Rept. 100-164, 100th Cong., 1st 
Sess. (1987).
---------------------------------------------------------------------------
    These actions served as precursors to a condition regarding 
treaty interpretation that was added in 1988 to the resolution 
of ratification on the INF Treaty.\35\ That condition 
articulated what it said were the constitutional principles 
that would govern the future interpretation of the treaty. The 
Foreign Relations Committee explained:
---------------------------------------------------------------------------
    \35\ Because of the administration's claims that the negotiating 
record of the ABM Treaty gave a more accurate indication of its meaning 
than administration testimony to the Senate, the Senate also sought and 
gained access to the negotiating record of the INF Treaty. But in its 
report on the INF Treaty, the Foreign Relations Committee took the 
position that Senate review of negotiating records should not become an 
institutionalized procedure, although reference to the record on a 
case-by-case basis sometimes might be useful. In the committee's view, 
``a systematic expectation of Senate perusal of every key treaty's 
negotiating record'' might inhibit candor during future negotiations 
and im
