Citations to international sources, such as a treaty or a case decided by an international court, are governed by Rule 21 of the Bluebook. Rule 21 also covers citations to documents published by certain intergovernmental organizations, such as the United Nations, European Union, and World Trade Organization with Tables 3-5. Citations to foreign materials, such as statutes of another country, is governed by Rule 20 of the Bluebook with Table 2. The rule and table do not specify all foreign countries' legal citations.
This Guide will focus on Rule 21.4 (Treaties and Other International Agreements), Rule 21.5 (International Law Cases), and 21.7 (United Nations Sources), 20.5 (Statutes), and provides guidance on how to format the citation for each source.
Citation of a treaty or other international agreement generally includes the following information: (1) name of the agreement, (2) parties to the agreement, if applicable, (3) subdivisions, if citing only part of an agreement, (4) date of signing, and (5) the source(s) where the treaty or agreement can be found. The citation will be different based on whether the treaty or agreement is between two parties or multiple parties.
In the following citation examples, the relevant portion discussed in each heading or paragraph is highlighted in blue for purposes of illustration only.
Name of Agreement (Rule 21.4.1)
The name of the treaty or agreement should include both its form and subject matter. The agreement could take various forms, such as an agreement, convention, memorandum, protocol, treaty, or understanding. If the name includes more than one form, use only the first form that appears on the title page, unless doing so would create ambiguity.
Convention
Not: Convention & Supplementary Protocol
The subject matter of the agreement can be found in the title of the agreement.
Kyoto Protocol to the United Nations Framework Convention on Climate Change
The citation should provide the treaty name in English, but if there is no English-language name available, follow the rule for non-English language documents under rule 20.2.2, which requires the name to appear in the original language for the first citation. A shortened name or the full name in English may appear in brackets following the original-language name.
Verdrag tot het Vermijden van Dubbele Belasting [Agreement for the Avoidance of Double Taxation], Neth.-Swed., art. 4, Apr. 25, 1952, 163 U.N.T.S. 131.
When citing to a treaty or agreement for the first time, the citation should provide the treaty’s full name. But if the full name is very long or if the treaty is commonly known by a popular name, the first citation should end with a bracketed “hereinafter” short-form citation that can be used in subsequent citations.
Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases, and of Bacteriological Methods of Warfare, June 17, 1925, 26 U.S.T. 571 [hereinafter Geneva Protocol].
Geneva Protocol, supra note 1, at 572.
Parties to the Agreement (Rule 21.4.2)
When citing to a bilateral treaty, the citation should indicate both parties, whose names should be abbreviated according to T10 and appear in alphabetical order with a hyphen in between.
Treaty of Friendship, Commerce and Navigation, Japan-U.S., art. XI, ¶ 1, Apr. 2, 1953, 4 U.S.T. 2063.
Subdivisions (Rule 21.4.3)
When citing to only part of an agreement, or when citing an appended document, the citation should provide the subdivision or appended document. Citation to a subdivision of an agreement can include the article, paragraph, or section number instead of a pincite for the treaty series.
Treaty of Friendship, Commerce and Navigation, Japan-U.S., art. XI, ¶ 1, Apr. 2, 1953, 4 U.S.T. 2063.
Date of Signing (Rule 21.4.4)
The citation should give the exact date of signing, but if the treaty was not signed on a single date, give the date on which the treaty was open for signature, approved, ratified, or adopted, and indicate the significance of the date in italics. Other relevant dates, such as the date on which a treaty entered into force, may be included in a parenthetical at the end of the citation.
Treaty of Friendship, Commerce and Navigation, Japan-U.S., art. XI, ¶ 1, Apr. 2, 1953, 4 U.S.T. 2063.
Treaty on the Non-Proliferation of Nuclear Weapons, opened for signature July 1, 1968, 21 U.S.T. 483, 729 U.N.T.S. 161.
U.N. Convention on the Law of the Sea, opened for signature Dec. 10, 1982, 1833 U.N.T.S. 397 (entered into force Nov. 16, 1994).
Treaty Sources (Rule 21.4.5)
The Bluebook provides a list of international treaty sources in T4. The treaty source that should be used in the citation depends on whether the United States is a party to the treaty, and whether the treaty is a bilateral or multilateral treaty.
For bilateral treaties between the United States and another party, cite one of the following sources, in the following order of preference: U.S.T. (or Stat.); T.I.A.S. (or T.S., or E.A.S.); U.N.T.S.; Senate Treaty Documents or Senate Executive Documents; the Department of State Dispatch; Department of State Press Releases.
Treaty of Friendship, Commerce and Navigation, Japan-U.S., art. XI, ¶ 1, Apr. 2, 1953, 4 U.S.T. 2063.
For multilateral treaties to which the United States is a party, cite one of the U.S. domestic sources listed for bilateral treaties above, if therein. Citation of a multilateral treaty may include a parallel citation from a source published by an international organization, such as U.N.T.S., L.N.T.S., O.A.S.T.S., Pan-Am. T.S., O.J., E.T.S., or C.E.T.S.
North Atlantic Treaty art. 5, Apr. 4, 1949, 63 Stat. 2241, 34 U.N.T.S. 243.
For treaties or agreements to which the United States is not a party, cite one of the sources published by an international organization listed above, if therein. If not, cite the official source of one signatory with a parenthetical indicating the jurisdiction of the source unless it is clear from the context.

Citation for an international law case largely follows rule 10 but is slightly modified. In general, it includes the following information: (1) name of the case, (2) case number, (3) reporter, if any, (4) characterization of the decision, (5) pincite, and (6) parenthetical with the date, prefaced by the name of the court if it is not evident from the citation. A decision can be characterized as judgment, order, advisory opinion, provisional measures, among others. Paragraph numbers, rather than page numbers, should be used for a pincite in an international law case.

Statutes in Common Law Systems (Rule 20.5.1)
When citing to statutes from a Common Law System, you should format your citation like a U.S. statutes (Rule 12) if the jurisdiction's statutes appear in a codification or other compilation.
[Official Name of the Act], [volume number] [compliation abbreviation] [first page], ([date range of compliation cited]) ([jurisdiction abbreviation if not evident from context]).
For example, this citation for the Extradition Law of Israel which was published in the Laws of State of Israel (LSI), which contains the authorized English translation of legislative enactments from 1949 to 1989. You will note, according to T2, Israel statutes must contain "[Hebrew Calendar year of enactment] - [Gregorian calendar year of enactment]," shown in blue text below.:
Extradition Law, 5714-1954, 8 LSI 144, (1953-1954) (Isr.)
Otherwise, cite like statutes of the United Kingdom using Table T2.42 - United Kingdom, noting the jurisdiction parenthetically at the end of the citation if not otherwise clear from the context.
[statute short title, where available] [year(s)], c. [chapter number(s)], §(§) <section number(s)>, sch(s). [schedule(s), if any] ([jurisdiction abbreviation if not evident from context]).
It is important to always reference the Table 2 in your Bluebook for the specific jurisdiction as each jurisdiction may have its own nuances. For example this Emergency Powers Act from Ireland, Table 2.21 requires the [Act Number or Public Statute Number] / [year] be included, as shown below:
Emergency Powers Act, 1976 (Act No. 33/1976) (Ir.).
Statutes in Civil law and Other Non-Common Law Jurisdictions (20.5.2)
When citing generally to statutes in civil law or other non-common law jurisdictions, you should use the Table T2. When citing a code, do not indicate the year of the code unless citing a version no longer in force. In accordance with rule 20.2.3, use the full publication name the first time the publication is cited, indicating in brackets the abbreviation that will be used subsequently. Thereafter, the abbreviated form may be used. Give the publisher or editor and date of privately published sources only when citing an annotation rather than the code itself.
According to Bluebook Rule 21.7, United Nations materials fall into six major categories:
1. Verbatim/Summary Records (Rule 21.7.1)
The minutes or full-text transcripts of the sessional meetings of various UN bodies can be found here. Complete transcripts of meetings or “verbatim” records as they are called by the Security Council (SC), the General Assembly(GA), and the Trusteeship Council (TC) are kept in the Official Records of those organs. The Economic and Social Council (ECOSOC) and the Trade and Development Board do not maintain verbatim records, just minutes. All citations to verbatim and summary records should be to the Official Records whenever possible. References to the Official Records of these bodies are abbreviated GAOR, SCOR, etc. (See Table T.3 in the Bluebook).
Official records also include "Annexes," which republish selected mimeographed documents. "Supplements" are also part of the Official Records. Some supplements also contain annual reports of various commissions and committees submitted to their parent body.
U.N. GAOR, 56th Sess., 1st plen. mtg at 3, U.N. Doc. A/56/PV.1 (Sept. 12, 2001).
2. Resolutions (Rule 21.7.2):
According to the Bluebook, “[t]he final, authorized version of resolutions appear in the Official Records. However, it has become customary to cite the electronic versions found in the Official Document System (ODS) of the United Nations using resolution symbols. Cite resolutions either to the Official Records or using resolution symbols.”
General Assembly resolutions and decisions are compiled into sessional cumulations that have traditionally been published as the final supplement to the Official Records of the General Assembly. However, from the 42nd session (1987-1988) onwards, Supplement No. 49 has been designated to contain the resolutions and decisions of a given regular session.
Security Council resolutions and decisions are compiled into annual cumulations which are issued in the S/INF/- series as part of the Official Records of the Security Council.
G.A. Res. 47/1, ¶ 33, U.N. Doc. A/RES/47/1 (Sept. 22, 1992).
3. Reports (Rule 21.7.3)
According to the Bluebook, when citing reports from UN committees the citation should include the name of the body and the subcommittee, if any, the title of the report, the document symbol, and the date. Many reports of major bodies of the General Assembly are printed as supplements to the Official Records.
U.N. Econ. & Soc. Council [ECOSOC], Sub-Comm. on Prevention of Discrimination & Prot. of Minorities, Working Group on Minorities, Working Paper: Universal and Regional Mechanisms for Minority Protection, ¶ 17, U.N. Doc. E/CN.4/Sub.2/AC.5/1999/WP.6 (May 5, 1999) (prepared by Valdimir Kartashkin).
4. Sales Publications (Rule 21.7.7): Sales publications are important annuals, statistical compendia, individual studies, etc., available for purchase from the UN. An example of a sales publication is the Yearbook of the United Nations. Sales publications are assigned unique UN Sales Numbers (e.g., E.92.IV.1). When citing a Sales publication, Bluebook Rule 21.7.7(d) also requires citation to the Sales Number.
Search JACOB, the Jacob Burns Law Library’s online catalog to identify Library holdings of individual sales publications.
5. Masthead Documents (Rule 21.7.4)
Also known as "mimeographed documents", these are the first and only published format for many U.N. documents. They include draft documents, the initial publication of important items such as resolutions, as well as many ephemeral items of marginal interest to those outside the organization. Each masthead document has a U.N. document symbol (its unique identification number). There is nothing in the document symbol, however, to indicate to the user whether or not something is a mimeo document. Most collections of mimeo documents, whether in paper or microfiche, are arranged by the U.N. document symbols, for example, A/46/468.
6. Yearbooks and Periodicals (Rule 21.7.8)
The UN publishes a number of yearbooks and periodicals, such as the Yearbook of the United Nations and the U.N. Chronicle.
The Bluebook also provides rules for the citation of UN Press Releases and Memoranda (Rule 21.7.5), Adjudicatory Bodies Established by the UN (Rule 21.7.6), Regional Organization Documents (Rule 21.7.9) and the UN Charter (Rule 21.7.10).
Summary Records of the 1447th Meeting, [1977] 1 Y.B. Int'l L. Comm'n 175, U.N. Doc. A/CN.4/SER.A/1977.
Most U.N. documents are identified by an alphanumeric number called a "U.N. document symbol." An example of a document symbol is: E/CN.4/Sub.2/1993/23/Rev.1. The letters in the U.N. document symbol system identify the issuing body and that body's place in the hierarchy of the U.N. organization. In the above symbol:
E = Economic and Social Council (ECOSOC); the parent body
CN.4 = Commission on Human Rights
Sub. 2 = Sub-Commission on Prevention of Discrimination and Protection of Minorities
1993 = document year
23 = 23rd document
Rev.1 = Revision 1 of the document
Slashes (/) separate the various elements of the U.N. document symbol. This distinguishes the symbols from other numbering systems such as U.N. sales numbers (which use periods).
The first letter appearing in the U.N. document symbol denotes the major U.N. organ from which the document originated. The most common symbols and their corresponding U.N. organs are:
A/- General Assembly
E/- Economic and Social Council (ECOSOC)
S/- Security Council
ST/- Secretariat
T/- Trusteeship Council
Following the first slash in the U.N. document number are acronyms denoting other parent bodies:
/CCPR/- Human Rights Committee
/CERD/- International Convention on the Elimination of All Forms of Racial Discrimination
/TD/- U.N. Conference on Trade and Development (UNCTAD)
/UNEP/- U.N. Environment Programme
Following the second slash, letter abbreviations refer to a specific type of organization:
/AC./- Ad-Hoc Committee
/C./- Standing or permanent committee
/CN./- Commission
/CONF./- Conference
/SC./- Sub-committee
/Sub./- Sub-commission
/WG./- Working Group
After the third slash, the type of document is indicated by the following letters:
/PV/- Verbatim records of meetings (procès verbaux)
/RES./ - Resolution
/SR./- Summary record of meeting
/WP./- Working Paper
A modification of the text is indicated after the fourth slash:
/Add./- Addendum (Indicates an addition of text to the main document)
/Amend./- Amendment (Alteration, by decision of a competent authority, of a portion of an adopted formal text.)
/Corr./- Corrigendum (Indicates modification of any specific part of an existing document to correct errors, revise wording, or reorganize text.)
/Rev./- Revision (Indicates a new text which supersedes and replaces that of a previously issued document)
Following the fourth slash, letters denoting distribution status are listed:
/L._ Limited (documents for which wide circulation is not desired because of their temporary nature (draft resolutions, draft reports, preliminary action documents.)
/R._ Restricted (Applies to documents whose confidential contents require that they be withheld from public circulation. Note: these documents are usually unavailable)
