This class will focus on treaties and other international agreements to which the U.S. is a party. We will also look at some resources for treaties to which the U.S. is not necessarily a party.
U.S treaty research involves both U.S. domestic law and international law.
Definition: in international law "an international agreement concluded between States in written form and governed by international law...whatever its particular designation." (Vienna Convention of the Law of Treaties (1969), 1155 U.N.T. S. 331.). On the international plane, doesn't matter whether called agreement, convention, pact, charter, protocol, treaty, or exchange of notes. United Nations Treaty Reference Guide provides an overview of treaty terminology. But in U.S. usage "treaty" has special meaning, see below, Treaties vs. "Executive Agreements."
Treaty-making process (international level): basic terminology
Bilateral treaties are between two parties; multilateral treaties are between more than two parties.
A multilateral treaty is negotiated and drafted, sometimes at a diplomatic conference. Once the text has been concluded (done), it is signed by representatives of the countries (States) involved in the negotiation. The treaty will come into force (enter into force) once the specified number of States -- having first completed the necessary treaty approval process at the domestic level -- have deposited their instrument of ratification (or acceptance or approval) with the necessary depositary. This is the step by which a State becomes a party to a treaty. States that were not among the original signatories can later accede to the treaty. A State's ratification may be conditioned by reservations.
Bilateral treaties are negotiated and drafted by representatives of the two parties and enter into force as specified in the treaty.
United States Treaty Practice
Treaties vs. "Executive Agreements"
- "Treaty": by executive branch, with "advice and consent" of Senate. President has the "[p]ower, by and with the Advice and Consent of the Senate, to make Treaties, provided two-thirds of the Senators present concur." (Const., Art.II, Sec. 2, cl. 2). As domestic law, on a par with statutes ("Supreme law of the Land") (Const., Art. VI, cl. 2), as long as "self-executing."
- "Executive agreements" don't go through the Senate, but are internationally binding. Negotiated by a governmental agency with authorization of the State Department. There are many more executive agreements than treaties. On international level, U.S. is bound. As domestic law, there might be question as to whether they are on a par with statutes.
- U.S. Department of State Foreign Affairs Manual, on the negotiation and conclusion of treaties and other international agreements sets out criteria for determining type of agreement. See 11 FAM 723.
Treaty-Making Process (at U.S. level):
- Negotiation is authorized by Secretary of State, treaty is negotiated by the executive branch, signed by representatives of the countries ("done" or "concluded"); President sends to Senate, with letter of transmittal, letter of submittal from Secretary of State, along with a report from the Secretary of State that outlines the negotiating background and describes the agreement's provisions in detail. Usually includes the full English text of the treaty. The "transmittal package" is published as a Senate Treaty Document (the first citable form) once the injunction of secrecy has been removed. This is the best available working text of a treaty ("draft treaty"). Senate Treaty Documents, from the 104th Congress (1995-1996) on, are available at the FDsys website and in HeinOnline .
- Sent to the Senate Foreign Relations Committee; hearings; if approved, a Senate Executive Report is sent to the full Senate recommending advice and consent; it includes explanatory material, reservations, understandings, declarations (see the "Resolution of Ratification"). This report is the most important "legislative history" material at the domestic level. Senate Executive Reports, from the 104th Congress (1995-1996) on, are available at the FDsys website. Reservations, etc., are also later printed in the Congressional Record in connection with the Senate vote on advice and consent to ratification. (For negotiating history at international level, see the "travaux prÉparatoires".)
- If approved by full Senate (requires 2/3 vote), goes back to President along with a resolution of advice and consent; president sends it to Secretary of State, who prepares instrument of ratification; President signs instrument of ratification and proclaims the treaty. Treaty is deposited with the designated depositary. The U.S. is now a party. The treaty is in force for the United States on the international plane (assuming requisite number of states have ratified). As domestic law, usually date of proclamation.
- By judicial doctrine, a treaty may be found to be self-executing or non-self-executing, i.e., requiring implementing legislation to become effective domestically. The implementing legislation becomes the rule of decision for U.S. courts.
Agreement-Making Process (at U.S. level):
- Secretary of State authorizes negotiations
- U.S. representatives negotiate
- Secretary of State authorizes signing
- Agreement enters into force
- President transmits to Congress (Case-Zablocki Act)
- Exception: Trade Promotion Authority, formerly "Fast-Track," process for trade agreements (expired in 2007). Majority vote of both houses, no amendments. A type of 'congressional â€“ executive" agreement.
Publication of U.S. treaties and other international agreements
Unofficial sources for recent treaties and international agreements:

- LexisNexis U.S. Treaties on Lexis (USTRTY file). From 1776 through current. "Full-text ratified and unratified treaties and international agreements, where the United States is a party or signatory."
- Westlaw U.S. Treaties and Other International Agreements (USTREATIES database). From 1778 to present, and Senate Treaty Documents from 103d Congress, 1993. Full text of international and American Indian treaties to which the U.S. government is a party. Includes proprietary "KAV" numbers.

Treaty Research: 3 aspects
- Finding an authoritative text (or finding whether a treaty on a certain subject exists, and then finding the text);
- Determining status: whether it is in force, for what parties, and with what reservations;
- Interpreting the treaty. This can involve legislative history (possibly both international level and domestic level) and how construed in the courts (can be both international and domestic);
1. Finding the text of a U.S. treaty:
Finding a Citation:
2. Status: Is it in force, for what parties, and with what reservations?
Treaties in Force as updated by the Treaty Actions section of U.S. Dept. of State web site. For the most recent information call Dept. of State Office of Treaty Affairs. Note: the texts of a country's reservations are printed in Multilateral Treaties Deposited with the Secretary-General, published annually by the United Nations and updated on the United Nations Treaty Collection website. For U.S. reservations, see also Senate Executive Report. Treaties in Force includes URLs for the depository organization and the depository's status chart for the treaty.
- For status of draft treaties:
- Website of U.S. Senate -- Legislation and records -- treaties
- Thomas -- Treaties page
3. Interpreting the treaty
(a) "Legislative History" of United States treaties
- Legislative history (negotiating history) at international level is not the same as legislative history at U.S. level. (At international level, "travaux prÉparatoires," conference proceedings, etc.)
- Legislative history of the implementing legislation, for non-self-executing treaties
- Senate Executive Report (from the Senate Foreign Relations Committee) is the most authoritative legislative source
- ProQuest Congressional Search in â€œCongressional Materialsâ€ (not â€œLegislative Historiesâ€) for citations to Senate Treaty Documents and Senate Executive Reports; some available in full text.
- CIS Index. Use the index volumes (not the legislative history volumes) to find citations to Senate Treaty Documents, Senate Executive Reports, hearings, etc.
D,REF Z 1223 .Z7C56 (Library no longer subscribes to hard copy)
- Wiktor, Christian L., Treaties Submitted to the United States Senate: Legislative History, 1989-2004 (Martinus Nijhoff Publishers, 2006)
I,MON KF 4989 .W55 2006
(b) Judicial Interpretation of a United States treaty:
- LexisNexis and Westlaw used as a citator to find cases (federal and state).
- United States Code Service, special volumes. selective coverage of major agreements includes interpretive notes and decisions. Available in Lexis.
