            Congressional Research Service,
                           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\
