Researching Public International Law
Last Updated December 2017
This guide is designed to enable you to do research in international law. It will introduce you to the basic concepts, institutions, texts, and research tools and give you a framework to knit these together as needed to solve individual problems. Underlying the guide is the principle that in order to understand what you need to find, you have to understand the institutions which are in a position to "create" international law. The guide is not intended to teach substantive law, but the framework within which the law is disseminated.

Definitions of International Law
Public International Law is the law of the political system of nation-states. It is a distinct and self-contained system of law, independent of the national systems with which it interacts, and dealing with relations which they do not effectively govern. Since there is no overall legislature or law-creating body in the international political system, the rules, principles, and processes of international law must be identified through a variety of sources and mechanisms. This can make international law appear difficult to pin down. Students and scholars in the United States often use the Restatement of the Law (Third), the Foreign Relations of the United States as a guide to identifying international law as applied in the US.
ALI Restatement 3rd, Section 101, International Law Defined:
"International law, as used in this Restatement, consists of rules and principles of general application dealing with the conduct of states and of international organizations and with their relations inter se, as well as with some of their relations with persons, whether natural or juridical."
The American Law Institute began working on the fourth iteration of the Foreign Relations Law of the United States in 2013. This new restatement will be different in that Treaties, Sovereign Immunity, and Jurisdiction will be divided into different sections. As of the 2017 Annual Meeting, the Tentative Drafts were approved. These can be found in print in the library as well as in the American Law Institute Library on HeinOnline.
From the Oxford English Dictionary:
"[I]nternational law, the law of nations, under which nations are regarded as individual members of a common polity, bound by a common rule of agreement or custom; opposed to municipal law, the rules binding in local jurisdictions."
Institutions Involved in the Process
As international law developed in the 17th and 18th centuries, it was widely understood that it was a tool for relations between nation-states. Individuals had no role in the process which resolved disputes between states except as representatives of the states, such as diplomats or naval officers. The classic ‘player’ is the sovereign body of the nation in whatever form it takes for a given state. It can be the President, Prime Minister, King, or Queen, but it is now often the bureaucratic representation of the sovereign power, such as the State Department, the Foreign Ministry, the military, etc. Until the middle of the 20th Century, international law consisted primarily of custom. More recently, customary international law has been increasingly codified.
While that part of the governmental entity charged with foreign relations will have the lead role in developing international law for the country, in practice each subunit of a government has some ability to create what can be recognized as International Law. In the United States, for example, the Executive Branch (acting through the State Department) may sign a treaty, but the President ratifies it with the "advice and consent" of the Senate, and the Congress as a whole may pass laws implementing it. In addition, administrative agencies can make and enforce regulations implementing the treaty and the statutes, and the courts can interpret any of the above and use non-treaty related international law as an exercise of their judicial power.
On the global scale, international organizations such as the United Nations and the European Union have become extremely important as forums for creating international law. The most recent development in this area has been the recognition that there is a role, within the sphere of public international law, for individuals to pursue remedies against sovereign nations.
Identification of Authoritative Texts
The Charter of the United Nations establishes the International Court of Justice (ICJ) as the principal judicial organ of the UN. The treaty which establishes the ICJ is informally known as the "Statute." Article 38 of this "Statute" furnishes an indirect answer to the question: What are the texts of international law? The article is written in terms of what sources the court will use in order to resolve a dispute. These sources include treaties, customary law, case law, academic writings, and general principles of law. Article 38 reads:
1. The Court, whose function is to decide in accordance with international law such disputes as are submitted to it, shall apply:
- a. international conventions, whether general or particular, establishing rules expressly recognized by the contesting states;
- b. international custom, as evidence of a general practice accepted as law;
- c. the general principles of law recognized by civilized nations;
- d. subject to the provisions of Article 59, judicial decisions and the teachings of the most highly qualified publicists of the various nations, as subsidiary means for the determination of rules of law.
2. This provision shall not prejudice the power of the Court to decide a case ex aequo et bono , if the parties agree thereto.
A different presentation of these ideas can be found in the Restatement of the Law 3d: Foreign Relations Law of the United States , Articles 102 (Sources of International Law) and 103 (Evidence of International Law).
§ 102 Sources of International Law
(1) A rule of international law is one that has been accepted as such by the international community of states
(a) in the form of customary law;
(b) by international agreement; or
(c) by derivation from general principles common to the major legal systems of the world.
(2) Customary international law results from a general and consistent practice of states followed by them from a sense of legal obligation.
(3) International agreements create law for the states parties thereto and may lead to the creation of customary international law when such agreements are intended for adherence by states generally and are in fact widely accepted.
(4) General principles common to the major legal systems, even if not incorporated or reflected in customary law or international agreement, may be invoked as supplementary rules of international law where appropriate.
§ 103 Evidence of International Law
(1) Whether a rule has become international law is determined by evidence appropriate to the particular source from which that rule is alleged to derive (§ 102).
(2) In determining whether a rule has become international law, substantial weight is accorded to
(a) judgments and opinions of international judicial and arbitral tribunals;
(b) judgments and opinions of national judicial tribunals;
(c) the writings of scholars;
(d) pronouncements by states that undertake to state a rule of international law, when such pronouncements are not seriously challenged by other states.
Since the adoption of the ICJ statute in 1946, the post-World War II growth of a wide variety of Inter-Governmental Organizations (IGOs) has injected the work product of these IGOs into the mix as well.
How International Law Texts are Created
The ICJ statute shows that International Law does not have an easily identifiable "law-giver". Under these circumstances, how do we find out if something is a rule in international law? What is it we are looking for? The ways norms are identified as international "law" include: agreements negotiated by the affected parties, deference to a third-party decision-maker, academic persuasion and consensus, and custom (state practice and the opinion that the practice is dictated by a legal obligation).
It is important to remember that there are two allied meanings of the word "source". One sense is related to the origins of the relevant, substantive norms and principles. The other sense is grounded in identifying the actual texts involved in the process.
Agreements Negotiated by the Affected Parties
- Enactments by bodies established by treaties
- Resolutions of the United Nations General Assembly
- Directives of the European Union Commission
- Similar enactments by regional or subject-specific organizations
- Resolution of a dispute through mediation
Deference to a Third Party Decision-Maker
- Case Law
- International Courts of General and Limited Jurisdiction
- International tribunals
- National Courts, enforcing norms taken from international sources
- Arbitral Decisions
- Often used for resolving problems related to commercial deals with state enterprises
Academic Exposition, Synthesis, Persuasion, and Consensus
Custom: Observation of What States Actually Do and Say
- Publications and information systems of the State Department and its foreign equivalents, IGO’s, etc.
- National yearbooks International yearbooks
- Truth & Reconciliation Commission Reports
- The Restatement
When you visualize the sources of law for US domestic law, it is relatively easy to think in terms of statutes, cases, administrative regulations and perhaps a few other stray texts in a given jurisdiction. It is not realistic to transfer that basic orderliness to international law, but the next few sections will provide a framework for thinking about the sources of international law in a similar and systematic way.
There is a growing body of writing about the concept of "soft law" in international law. This grants a certain authority to norms which are not legally binding in a traditional understanding of international law. A good introduction to this idea and an exploration of its use in certain fields can be found in a book called Commitment and Compliance (JX4171 .O3 C67 2000, 2nd Floor) edited by Dinah Shelton for the American Society of International Law.
General Introductory Materials
As in any field of knowledge, international law has a special vocabulary. While many of the terms will be found in general law dictionaries, such as Black’s or Ballantine’s, the dictionaries listed below focus on international law.
- The leading English language international law dictionary is the Parry and Grant encyclopedic dictionary of international law. New York: Oxford University Press, c2009 (KZ1161 .P37 2009, 3rd Floor Reference Collection).
- A shorter and simpler dictionary is James Fox's Dictionary of international and comparative law, 3rd edition. Dobbs Ferry, NY: Oceana Publications, c2003 (KZ1161 .F69 2003, 3rd Floor Reference Collection & 3rd Floor Reserve Dictionaries).
- Ernest Lindbergh's Modern dictionary of international legal terms : English, French, German. Boston: Little, Brown, c1993 (JX1226 L64 1993, 3rd Floor Reserve Dictionaries). This is useful to find translations of legal terms from one language into the others.
A similar polyglot international law dictionary is Kokusai kankeiho jiten. Tokyo: Sanseido, c2005 (KZ 1161.K647 2005, 2nd Floor East Asian Reference Collection).
The publication of the initial parts of the Encyclopedia of public international law (JX1226 En19a 1992, 2nd Floor) in the 1980's was a godsend to researchers, teachers,and students of international law. It was issued throughout the 1980's in 12 slim hardbound volumes, each on a theme within international law, such as the Law of the Sea, International Organizations, or Geographic Issues. In 2003 an updated and integrated version was completed. Each article is written by an expert in that particular area of the law, and is accompanied by a basic bibliography of sources for the substance of the article. These bibliographies are the parts which have become most outdated, but they are very good starting points for basic research. Since 2008, the Max Planck encyclopedia of public international law has been available as a fully updated online edition available through Oxford University Press.
Other useful encyclopedic tools include:
- Osmanczyk, Edmund Jan & Anthony Mango, Encyclopedia of the United Nations and international agreements. New York: Routledge, c2003 (KZ4968 .O84 2003, 3rd Floor Reference Collection).
- Lawson, Edward & Mary Lou Bertucci, Encyclopedia of human rights. Washington, DC: Taylor & Francis, c1996, (JC571 .E67 1996, 3rd Floor Reference Collection).
The best single exposition of traditional public international law was James Brierly’s The Law of Nations: an introduction to the international law of peace (JX2000 B76L4 1963, 2nd Floor).While it is dated, it is short and well written. A newer work, Vaughn Lowe's International Law (KZ1242 .L69 2007, 4th Floor), has been written to be a conscious successor to Brierly as a concise introduction to the field. The leading current works are Oppenheim's international law (JX2000 Op5In8 1992, 3rd Floor Reserve) 9th ed, edited by Robert Jennings and Arthur Watts and Ian Brownlie's Principles of public international law (KZ3225.B76 A37 2008, 3rd Floor Reserve) 7th ed.
In terms of the American understanding of international law, the two leading works are both local: Professor Henkins's International law: politics, values and functions: general course on public international law (JX2000 H389In8, 2nd Floor), is a good, broad review from 1989. It was prepared for presentation at the famous Hague Academy of International Law and was originally printed in 1989 Recueil des Cours, IV, pp 9-416 (JX1295 .H1 1923c, 4th Floor). Professor Schachter's International law in theory and practice (JX2000 Sch11In81, 3rd Floor Reserve) was also the general course at the Hague Academy and the original text is found in 1982 Recueil des Cours, Volume V.
Some of the more important standard works which cover the entire breadth of international law include:
- International law edited by Malcolm Evans, 4th Ed., Oxford; New York: Oxford University Press, c2014 (KZ1242.I573 2014, 3rd Floor Reserve).
- Cassese, Antonio, International law. Oxford ; New York : Oxford University Press, c2005 (KZ3395.C25 A35 2005, 3rd Floor Reserve).
- Aust, Anthony, Handbook of international law 2nd Ed., Cambridge, UK ; New York : Cambridge University Press, c2010 (KZ3410.A97 2010, 4th Floor).
- Malanczuk, Peter, Akehurst's modern introduction to international law 7th rev. ed., London; New York: Routledge, c1997 (JX2000 M289Ak32 1997, 2nd Floor).
- Dupuy, Pierre-Marie, Droit international public 4th Ed., Paris : Dalloz, c1998 (JX2000 D9195D8 1998, 2nd Floor).
- Seidl-Hohenveldern, Ignaz, Völkerrecht 10th Ed.. Köln : C. Heymann, c2000 (JX2000 Se42V8 2000, 2nd Floor).
- Boggiano, Antonio, Introduccion al derecho internacional: relaciones exteriores de los ordenamientos juridicos. Buenos Aires : La Ley, c1995 (JX2000 B634In8 1995, 2nd Floor).
There are many others. And as might be expected, there are treatises in all sorts of narrow areas within international law. International law casebooks, such as Damrosch's International Law: Cases & Materials (KZ1242.5 .I578 2014, 3rd Floor Reserve) and Carter, Trimble and Bradley's International Law (KZ1242.5. C37 2007, Casebooks Cellar) can be a good place to start research. Many casebooks also have documentary supplements which are a useful source of texts, but neither casebooks nor their supplements should be cited. The official source needs to be cited in any final work product.
International Law is one of the particular strengths of the Diamond Law Library here at Columbia. The on-line catalog, Pegasus, is a rich resource both to identify specific materials and to learn the nature of publication in general.
Recent Research Guides
The standard work is Guide to international legal research (KZ1234 .G85, 3rd Floor Reference Collection) published by Lexis Publishing. The current edition is kept in the Reference Office, while previous editions are kept on the Fourth Floor. This was originally a special issue of the Journal of International Law and Economics in 1987. A key starting point on the web is the GlobaLex International Law site. It consists of around 40 research guides covering a number of topics, ranging from Silke Sahl's guide to Customary International Law (updated by Catherine Deane) to the narrow guide on International Marine Environmental Law by Arundhati Ashok Satkalmi.
In the middle 1990's, the American Association of Law Libraries (AALL) held a series of symposia dedicated to researching international and comparative law. These resulted in five books which combine introductory texts in specific subject areas with research guides. They are all very useful, but unfortunately, they were produced just as the Internet was starting to appear as a reliable and widespread resource, so some of the information is already out-of-date. All of them are located in the library or available in HeinOnline's Spinnelli's Law Librarian's Reference Shelf.

Treaties and Other Forms of International Agreements
Just as statutes are the main source of modern domestic law, treaties have become the key source of law in international law. The first subsection of Article 38 of the ICJ Statute specifically mentions "international conventions" expressly creating the law in an area between or among the party states. Section 102 (3) of the Restatement reads in part "(3) International agreements create law for the states parties thereto. . . ."
The definition of "treaty" in the OED reads:
"A contract between two or more states, relating to peace, truce, alliance, commerce, or other international relation; also, the document embodying such contract, in modern usage formally signed by plenipotentiaries appointed by the government of each state."
The third Restatement’s definition reads:
"§ 301 DEFINITIONS
As used in this Restatement, (1) "international agreement" means an agreement between two or more states or international organizations that is intended to be legally binding and is governed by international law. . . ."
This definition shies away from using the word "treaty" since it is intended to cover both treaties and "executive agreements" which are less formal but equally binding. There are a whole range of words that are used for agreements that are meant to have the force of law. Although treaty is the most common, others include Agreement, Charter, Convention, Covenant, and Protocol. Whatever particular designation is used, all have the same legal status.
The treaty-making process is highly analogous to the way contracts are arrived at in private law. The process involves negotiation, a signing by representatives of the parties, and ratification by the appropriate national bodies. In an ideal world, this is followed by publication of the text, but publication of treaties is far less regularized than publication of standard domestic law statutes.
There are two main classes of treaties: bilateral and multilateral, ie., with two parties or many parties. Double taxation and extradition treaties are usually bilateral, involving only two countries. Multilateral treaties are used to solve global or regional problems and to create global or regional institutions.
It is important to remember that treaties do NOT come into force when they are signed even though date of signing is an important citation element. Most treaties have a clause within them as to when they come into effect. This may be the date of ratification, the date parties have enacted required follow-on legislation, or, with multilateral treaties, the date when a set number of parties have ratified it. Parties who join a multilateral treaty which is already in force for some countries specify the date it comes into effect for themselves.
A general treatise on treaties is Anthony Aust's Modern Treaty Law and Practice (KZ1301 .A93 2013, 4th Floor) 3rd Ed. Another useful recent book on the subject is the ASIL produced National treaty law and practice(KZ1301 .N38 2005, 4th Floor).
Publication of U.S. Treaties
The governmental publication of treaties in the US is somewhat irregular. Often the text first appears as a "Treaty Document", distributed when the President submits the treaty to the Senate for ratification. For multilateral treaties that are the result of many years negotiation, the draft treaty is often available from the body that is coordinating the development of the final text. In the early years of the republic, treaties appeared as part of the Statutes-at-Large, but that was not regular. Several compiled editions of treaties were published in the early part of the 20th century, culminating in Bevans’ Treaties and other international agreements of the United States of America, 1776-1949 (JX236 1968, Offsite Storage). The entirety of Bevans is also available in HeinOnline.
In the late 1940's the federal government developed a systematic way of publishing treaties and executive agreements that lasted until the grim budget cuts of the early 1980's. This involved initial publication in slip form known as TIAS, which stands forTreaties and other International Acts Series. These are compiled and republished as chronological hard-bound volumes known as UST, or United States treaties and international agreements (JX235.9 A5, Offsite Storage). The UST is also available through HeinOnline. This system still exists in a withered, almost parodic, form, with texts published in a desultory manner. The most recent volume of the UST was received by the Diamond Law Library in April, 1998 and covered treaties ratified in 1984. We received some TIAS pamphlets in 2000, covering agreements from 1995, but there are many in the numbered series which have not been published, going back to the 1980's. HeinOnline’s World Treaty Library does have TIAS Agreements from 1982-2017.
As mentioned above, often treaty texts can be found as a Congressional "Treaty Document". These are published by the Government Publishing Office (GPO) in support of the ratification process during the period between the President's transmission of the treaty for ratification and the actual ratification by the Senate. This format was adopted in 1980 and the paper versions are foundon the 2nd floor at JX231 Se54. Before that they were part of a set known as the Senate "Executive Document" series also available on the 2nd Floor at JX231 Se53). The digital version of these texts since 1995 can be found through the GPO's database govinfo.gov.
The U.S. Department of State provides a list of websites that the Office of Treaty Affairs utilizes to gather useful information about treaties and international agreements and obtain texts of the agreements.
NOTA BENE (NB): Since this guide was originally written, a similar guide focusing only on treaty research was created by Simon Canick and maintained by Silke Sahl. It is found at http://library.law.columbia.edu/guides/Guide_to_Treaty_Research. That guide supersedes my original text, most of which has been deleted as of August, 2007.
The basic multilateral form is: (1) name of the treaty, (2) the full date of the signing, (3) a citation to where it is published.
NB: For bilateral treaties involving the U.S. citation should be to 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 or Department of State Press Releases in that order of preference. For multilateral treaties to which the U.S. is a party, citation should be provided to one of the U.S. sources previously mentioned and a parallel citation may be added from a source published by an international organization. If the U.S. is not a party, citation should be to a source published by an international organization (Bluebook Rule 21.4.5).
Many treaties, especially older ones, are known by the place they were signed. The "Treaty of Rome" for example, founded the European Economic Community in the 1950's. Other multilateral treaties are commonly known through acronyms. An example is CITES, for the "Convention on International Trade in Endangered Species".
The details of the rules and the hierarchies of publications to be cited are found in Rule 21 of the BlueBook .
Approaching Treaty Material
From the researcher’s point of view, the first question you need to ask yourself in analyzing a situation is "Is there a treaty or group of treaties which covers this subject?" If yes, the next questions are related to locating the actual text itself and ascertaining its status.
- Is the treaty bilateral or multilateral?
- What is the text of treaty?
- Who are the parties?
- Is it in force?
- Modified by later treaty/ies?
- Has it been incorporated into domestic law of the relevant countries, if necessary?
- Did it create some form of body or international organization which now administers the international law in that subject area?
In any given situation, only some of these questions may be relevant. However, the initial step is to consult the indices of treaties to find out what’s out there.

A final note or segue: Treaties may have the effect of helping redefine customary law, the subject of the next section. The Restatement section 102 (3) reads in full "International agreements create law for the states parties thereto and may lead to the creation of customary international law when such agreements are intended for adherence by states generally and are in fact widely accepted."
Custom and State Practice
The Restatement at Section 102(2) reads "Customary international law results from a general and consistent practice of states followed by them from a sense of legal obligation". The Comment to the section goes on to explain "Subsection (2), includes diplomatic acts and instructions as well as public measures and other governmental acts and official statements of policy, whether they are unilateral or undertaken in cooperation with other states. . . . For a practice of states to become a rule of customary international law it must appear that the states follow the practice from a sense of legal obligation ( opinio juris sive necessitatis ); a practice that is generally followed but which states feel legally free to disregard does not contribute to customary law." This idea is reinforced in Section 103(2)(d), discussing evidence of a rule, accepting as evidence "pronouncements by states that undertake to state a rule of international law, when such pronouncements are not seriously challenged by other states."
The overall concept is referred to as the "practice" of international law by such-and-such jurisdiction. It may be useful to consult the reporter’s notes to the Restatement for an extended discussion of the issues, including an acknowledgment of the possible circularity of definition and the process underlying the definition.
It follows that the sources used to substantiate Custom can be quite broad. The clearest sources are those documents from the appropriate institutions which assert that they are statements of customary international law. The institution should be the one within a given jurisdiction which has the power to make such statements, such as the Department of State for the United States. Thus diplomatic papers involving dispute resolution are prime source materials for international law.
In recognition of this, the Department of State periodically produces information about its work which includes letters and other documents relevant to international law. The best products were conscious digests of the work of the department, each covering a set period and each edited by an international law specialist. Early compilations tend to be known by the editor’s name, Wharton (1887), Moore (1906), and Hackworth (1944). The version known as "Digest of International Law" (JX237 W588, located in Offsite Storage) is edited by Marjorie Whiteman and is generally known as "Whiteman’s Digest". This is in 15 volumes, covering 1963-73. Later years are covered by the Digest of United States Practice in International Law, 1973-1980 (KZ21 .R68, 4th Floor); the Cumulative Digest of United States Practice in International Law, 1981-1988 (KZ21 .R681, 4th Floor); and the Digest of United States Practice in International Law, 1989-2012 (KZ21 .R6812, 4th Floor). Documents are also available on the Department of State website. Beginning with the 2011 Digest, the official version of the Digest is published exclusively online. Another resource is the publication of a kind of chronicle in each issue of the American Journal of International Law called "Contemporary Practice of the United States relating to International Law" written in consultation with the Department of State.
The website for the Department of State has a lot of raw materials for current activities, some of which is useful for international law purposes. The University of Chicago has an archive of DOS web materials. The unit within the Department of State which handles international law issues is the Office of the Legal Adviser.
Because of the fuzziness of sources in this area, the Restatement itself, especially given its explanatory text and reporter’s notes, is a strong statement as to U.S. practice. It should be noted, however, it was not written with the imprimatur of the State Department.
The best parallel tools for other jurisdictions tend to be the non-official yearbooks of international law for particular countries. These tend to combine academic articles on international law with a solid review of current practice and selected reprinted documents.
Leading Examples include (many are available in HeinOnline’s Foreign and International Law Resources Database):
- The Australian year book of international law (JX1 Au787, Offsite Storage & Cellar)
- The British year book of international law (JX1 B7, Offsite Storage & Cellar)
- The Canadian yearbook of international law / Annuaire canadien de droit international (JX1 C16, Offsite Storage & Cellar)
- The Finnish yearbook of international law (JX1 F497, Cellar)
- Annuaire français de droit international (JX1 An923, Cellar)
- German yearbook of international law / Jahrbuch für internationales Recht (JX1 J351, Offsite Storage & Cellar)
- The Italian yearbook of international law (JX1 It1, Cellar)
- Netherlands yearbook of international law (JX1 N386, Cellar)
- The Palestine yearbook of international law (JX1 P175, Cellar)
- Polish yearbook of international law (JX1 P747, Cellar)
- Schweizerisches Jahrbuch für internationales Recht / Annuaire suisse de droit international (JX1 Sch9, Cellar)
- South African yearbook of international law / Suid-Afrikaanse jaarboek vir volkereg (JX1 So7, Offsite Storage & Cellar)
Multi-jurisdictional examples include the African yearbook of international law (JX1 Af832, Cellar) and the Asian yearbook of international law (JX1 As42, Cellar). Yearbooks are also important in documenting the role of international organizations within international law (see below). The best yearbooks lead you to more solid materials by citing the actual texts involved with the perceived practice.
Some of this kind of privately edited material is starting to appear on the web. The text of the German Yearbook's section on practice is available on the Max Planck website.
Many countries now have websites for their equivalent of the Department of State. The contents vary enormously. Examples include:
- Australia: Department of Foreign Affairs and Trade
- China: Ministry of Foreign Affairs
- Germany: Auswärtiges Amt
- Israel: Ministry of Foreign Affairs
- Japan: Ministry of Foreign Affairs
- Russia: Ministry of Foreign Affairs
- United Kingdom: Foreign and Commonwealth Office
Breadth and Context
The sources presented above are related to practice in its narrowest sense. In fact, the totality of a nation’s "presentation of self" is its practice. This includes treaty participation and execution, actions of its administrative agencies, decisions of its courts, etc. All of this can be used as evidence of customary international law. Arguably, any institution which has the power in a given situation to decide that an assertion or action has the imprimatur of customary international law is in fact making it so. The limitation on this power is a jurisprudential one similar to the limits on the lawmaking power of a judge in Common Law.
For years the Department of State Bulletin (JX232 Un31, Offsite Storage & HeinOnline) was the official record of U.S. foreign policy from 1939-1989. It grew progressively less meaty and was replaced by a slim magazine Dispatch. Dispatch died at the end of 1999. The following text is adapted from the DOS website:
The United States Department of State Dispatch has provided key speeches and testimony by senior State Department officials as well as current U.S. treaty actions since 1990. However, since all speeches, briefings, and testimony from State Department officials and the current U.S. treaty actions are available on the web site upon release, hard copy distribution of this publication will end with the December 1999 issue and Index.
The formal historical record of the work of the Department of State is found in an enormous set of hundreds of volumes prepared by the Department’s Office of the Historian entitled the Foreign relations of the United States (JX233.A3 1862 Suppl, Cellar Microfiche). The current volumes cover the late 1960's. A good guide and volumes from the Truman Administration to the Reagan Administration are available on the Office of the Historican's website.
General Principles of Law
In relation to principles as a source of law, Article 38 of the ICJ Statute reads:
"1. The Court, whose function is to decide in accordance with international law such disputes as are submitted to it, shall apply: . . .
- c. the general principles of law recognized by civilized nations. . . ."
Reflecting on this, one authority has written:
Writers disagree on the substance and content of general principles of law, as well as on their legal scope and relationship with the other main sources, namely treaties and customary law.
Some authors link these principles with the idea of natural law. Some others, basing their views on arbitral compromises from the 19th century, connect them with equity. Following Grotius in this respect, Charles Fenwick was of the opinion that these principles were deduced from the fundamental principles of morality and justice, together with the more specific principles from civil law codes and from Anglo-Saxon Common law of judicial precedents.
Some authors see in the inclusion of general principles in Article 38 of the statute of the Hague Court, a defeat of positivism, i.e., an indication of the impossibility of reducing the entire system of international law to the will of the States. On the contrary, some other authors consider these principles as precepts of positive law, because of their being recognized by civilized nations’ and being rules in force in municipal legal systems of States. A third group of writers tend to reduce the application of these principles to the private law analogy or to legal reasoning in general."
This extended quotation is from pages 14 and 15 of V. D. Degan’s Sources of International Law, (Jx60 D363 1997, 2nd floor). I have quoted it at length to give warning of the overall mushiness of this area both in terms of the law and as a subject for research.
The Restatement, Section 102(4) reads:
"(4) General principles common to the major legal systems, even if not incorporated or reflected in customary law or international agreement, may be invoked as supplementary rules of international law where appropriate."
The comments and illustrations to this section include these thoughts;
General principles as secondary source of law: Much of international law, whether customary or constituted by agreement, reflects principles analogous to those found in the major legal systems of the world, and historically may derive from them or from a more remote common origin. . . . General principles common to systems of national law may be resorted to as an independent source of law. That source of law may be important when there has not been practice by states sufficient to give the particular principle status as customary law and the principle has not been legislated by general international agreement.
General principles are a secondary source of international law, resorted to for developing international law interstitially in special circumstances. For example, the passage of time as a defense to an international claim by a state on behalf of a national may not have had sufficient application in practice to be accepted as a rule of customary law. Nonetheless, it may be invoked as a rule of international law, at least in claims based on injury to persons . . . because it is a general principle common to the major legal systems of the world and is not inappropriate for international claims. Other rules that have been drawn from general principles include rules relating to the administration of justice, such as the rule that no one may be judge in his own cause; res judicata; and rules of fair procedure generally. General principles may also provide ‘rules of reason’ of a general character, such as acquiescence and estoppel, the principle that rights must not be abused, and the obligation to repair a wrong. International practice may sometimes convert such a principle into a rule of customary law."
It is interesting to note that the troublesome reference to "civilized nations" in the ICJ statute has evolved into the gentler "common to the major legal systems" in the Restatement.
The expression of this concept is more familiar to Civilians than it is to common lawyers. Most civil codes have a statement to the effect that in the absence of express law, judges can turn to general principles to resolve disputes.
Chilean Civil Code, Article 24 :
En los casos a que no pudieren aplicarse las reglas de interpretación precedentes, se interpretarán los pasajes obscuros o contradictorios del modo que más conforme parezca al espíritu general de la legislación y a la equidad natural.
The Civil Code of Qubec, Preliminary Provision, Clause One:
The Civil Code of Quebec, in harmony with the Charter of human rights and freedoms and the general principles of law, governs persons, relations between persons, and property.
Code Civile Suisse, Article 4:
Pouvoir d'appréciation du juge: Le juge applique les règles du droit et de l'équité, lorsque la loi réserve son pouvoir d'appréciation ou qu'elle le charge de prononcer en tenant compte soit des circonstances, soit de justes motifs.
An older book dedicated to this subject is Bin Cheng's 1953 monograph General principles of law: as applied by international courts and tribunals (KZ3225.C44 A34 1953, 4th Floor). A more recent article is Christopher A. Ford, Judicial discretion in international jurisprudence: Article 38(1)(C) and "general principles of law", 5 DUKE J. COMP. & INT’L. L. 35-86, (1994).
Case Law and Secondary Materials
The ICJ Statute Article 38 displays the traditional Civil Law perception of case law, that it is a strong form of persuasive authority, but of no greater weight than the writings of experts in journals and books. It is hard for a Common Law trained lawyer to swallow this. Section 103 (2)of the Restatement shows a more modern understanding of the value of case law:
(2) In determining whether a rule has become international law, substantial weight is accorded to
- (a) judgments and opinions of international judicial and arbitral tribunals;
- (b) judgments and opinions of national judicial tribunals;
- (c) the writings of scholars
The explanatory Comment states:
Article 59 of the Statute of the International Court of Justice provides: ‘The decision of the Court has no binding force except between the parties and in respect of that particular case.’ That provision reflects the traditional view that there is no stare decisis in international law. In fact, in the few permanent courts, such as the International Court of Justice, the Court of Justice of the European Communities, and the European Court of Human Rights, there is considerable attention to past decisions. . . . In any event, to the extent that decisions of international tribunals adjudicate questions of international law, they are persuasive evidence of what the law is. The judgments and opinions of the International Court of Justice are accorded great weight. Judgments and opinions of international tribunals generally are accorded more weight than those of domestic courts, since the former are less likely to reflect a particular national interest or bias, but the views of national courts, too, generally have the weight due to bodies of presumed independence, competence, impartiality, and authority.
International Law case law developed within a tradition of ad hoc tribunals established by agreements to arbitrate particular disputes, and a permanent "Court of Arbitration" was established at the Hague in 1899. This led to the creation of the Permanent Court of International Justice (PCIJ), established as an organ of the League of Nations in 1919. After World War Two, the PCIJ was replaced by the less ironically named International Court of Justice. A number of subject specific and/or regional institutions have developed international court systems within their structures. These include the courts related to the European Union, the Inter-American Court of Human Rights, the European Court of Human Rights, the Law of the Sea Tribunal, the WTO Tribunal, etc. The most recent truly international tribunal is the International Criminal Court, created in 1998.
While finding the case law of these institutions may seem relatively straightforward, some of the judicial systems are structured in ways that may seem odd to a novice. Opinions may be from an intermediate step rather than the final step in a proceeding. It is important to know the structure so you know the full authority of the text in hand.
An excellent new text which provides an introduction to the structure and procedure of all the major courts and similar institutions is the Manual on International Courts and Tribunals (KZ6250 .M36 2010, 3rd Floor Reserve) by Sands, Mackenzie, and Shany.
The International Court of Justice
This is the "world court", the single main tribunal for settling disputes between nations. It has a very useful website. Its decisions are considered the strongest statement on what international law is in the disputed situation.
In 1996 a fancy coffee-table book on the history of the court was published which serves as a good historical introduction:
- Eyffinger, Arthur, The International Court of Justice, 1946-1996. The Hague; Boston, MA: Kluwer Law International, c1996 (JX1976.C5 Ey37 1996, 2nd Floor).
The Yearbook of the ICJ (KZ6273 .I58, Offsite Storage & 4th Floor) contains a range of useful information, including basic texts, a list of all its cases, a presentation of the structure and procedure of the court, biographies of its current justices, summaries of that year’s cases, etc.
Other useful texts are:

The official reporter is:
- International Court of Justice, of judgments, advisory opinions and orders = Recueil des arrêts, avis consultatifs et ordonnances. Leyden: A.W. Sijthoff, c1947- (KZ214 .I58, 4th Floor).
ICJ cases are reprinted in a number of places, including unofficial reporters, journals, International Legal Materials, etc. It is best to cite to the official text.
There have been a number of attempts at digests, including:
- Syatauw, J. J. G, Decisions of the International Court of Justice: A digest. Leyden: A. W. Sijthoff, C1962 (JX1976.C5 Sy131, Offsite Storage).

Many, if not all, of the cases through the middle 1980's are also digested in the Encyclopedia of Public International Law (Jx1226 En19, 2nd Floor).
The ICJ’s predecessor under the League of Nations was known as the Permanent court of International Justice. Its decisions can be found in:
- Permanent Court of International Justice, Publications of the Permanent Court of International Justice. Series A/B, Judgments, orders and advisory opinions = Publications de la Cour permanente de justice internationale. Serie A/B, Arrets, ordonnances et avis consultatifs. Leyden : A.W. Sijthoff, c1922-1940 (JX1975.A5 P91, 2nd Floor)
The first thing to remember in regard to the regional courts in Europe is that there are two distinct systems. One is connected to the European Union (known for years as the European Communities) and handles issues related to the commercial and social effects of the EU system. The other is related to the Council of Europe and is devoted primarily to human rights and has no relationship to the European Union. There are areas where an outsider might be confused as to which court might take jurisdiction over a dispute. To make things worse, both Lexis and Westlaw combine the decisions of these court systems under European Union case law, reinforcing the temptation to confuse them. It may be helpful to remember that the European Court of Justice (EU) is based in Luxembourg, while the European Court of Human Rights is based in Strasbourg.
The Court System of the European Union
The European court system has evolved over the years. It originally had formal decision-making roles for a commission, for the Advocate-General, and for the Court. This has changed into a two step procedure centering on the Court of the First Instance and the Court itself. Texts which appear as decisions within the European Union judicial system may be from the Commission, the Court of the First Instance, or the European Court of Justice. Older cases may have had an opinion of the Advocate-General as well, but Court has stopped printing them in the official reporter.
The general website for the European Union Court System includes a section with recent decisions of the European Court of Justice and the Court of the First Instance.
Since the constitution of the European Union is in fact a sequence of treaties whose cumulative effect has been to been to change earlier texts, there are now specific rules for how to cite the various treaties.

The European Court of Human Rights, Strasbourg
The ECHR is a product of the European Convention on Human Rights and is administered through the Council of Europe. There used to be a two step commission / court structure, but the commission as a required preliminary hearing was dropped last year and there is now a "single court system".
The adoption of the principles of the convention into domestic law was one of the early objectives of the drafters. Different countries have done this at different speeds.

International Criminal Court
After many years of lobbying, drafting, and politicking, the Treaty establishing an International Criminal Court was signed in July, 1998. It is known as the "Rome Statute of the International Court". While the United States participated in the negotiations and drafting and a signature on December 31, 2000, the country informed the UN Secretary General on May 6, 2002 that the United States does not intend to become a party to the treaty and therefore has no obligation arising from the signature. The United States refused to become a party to the Treaty because of serious objections within the government to certain elements of its jurisdiction and procedure. There were 138 signatories to the Treaty and as of December 15, 2017, there are 123 parties to it. Sixty countries need to ratify it for the treaty to go into effect. As of December 15, 2017, 106 countries have ratified the Treaty, 15 have accessioned the Treaty, one country has accepted the Treaty, and one country has withdrawn from the Treaty.
The website developed in support of the negotiations is a model of its kind, with background documents, records of events, signatory and ratification information, etc. It only includes developments up to December 31, 2003, when the Permanent Secretariat of the Assembly of States Parties to the Rome Statute was adopted and the UN Secretariat stopped serving as Secretariat of the Assembly.
This project is aimed at strengthening the notion of international tribunals and developing support for these tribunals. It has two main components: "Research and Policy Dialogue" and "Capacity Building". The webpage has links to a large number of current international tribunals.

Many cases brought before national courts involve ascertaining international law or deciding international law issues. The research systems used for domestic law have the capacity to find material involving international law issues. Many of the yearbooks mentioned in the section on custom also have sections reviewing and digesting the international law related cases within the particular country.
In some countries there are special private reporters which select and publish that country’s international law cases. Examples of these include:
- British international law cases; a collection of decisions of courts in the British Isles on points of international law. London: Stevens, New York: Oceana Publications, c1964- (JX60 B77, Offsite Storage).

There has been one serious attempt to bring general international law decisions from all kinds of national courts into one publication. It is Lauterpacht’s International law reports (KZ199 .I58, 4th Floor & Offsite Storage), known earlier as Annual digest of public international law cases (1919-1932) and Annual digest and reports of public international law cases (1933-1949). While computerized law reporting from around the world has lessened the importance of this work, it has the virtue of providing translations of foreign cases, and it is a very good historical source.
Other Dispute Resolution Institutions
Many of the standard alternative dispute resolution systems are also used within the international legal processes.
The different ad hoc means of settling a dispute include Mediation, Conciliation, and Arbitration. In that order, each one represents a greater surrender of decision making authority to an outsider. A mediator works to get the parties to an agreement without any authority to force either party into any action. At the other end of the spectrum, in an arbitration the parties agree to abide by the arbitrator’s decision even if it completely against their point of view. Arbitration was especially important in the development of international law before the creation of permanent international courts, and has continued to be used in sensitive situations, like the dispute between New Zealand and France over the French Secret Service’s limpet mining of the Greenpeace ship "Rainbow Warrior" in a NZ harbor.
The decisions of arbitrators are a major source of case law within international law, and many efforts have been made to collect the reports of arbitral decisions in a public and systematic way. The only problem is that there is no formal obligation to publish the decision of an arbitration, so they can be hard to locate. The Diamond Law Library has many decisions in full as originally published by the parties. These were printed and catalogued individually. This unsystematic mode of distribution cries out for some sort of search tool, and a few have been developed.
The first major recompilation of arbitral and other decisions was:
- Moore, John Bassett ed., International adjudications, ancient and modern: history and documents: together with mediatorial reports, advisory opinions, and the decisions of domestic commissions, on international claims. New York: Oxford university press, c1929-1933 (JX1991 M78, Offsite Storage).
Besides setting up the ICJ and establishing the registry of treaties known as the UNTS, the United Nations took on the role of reporter of arbitral decisions if the parties consented to it. The result is a 20 volume series known as:
- Reports of international arbitral awards = Recueil des sentences arbitrales. United Nations: c1948- (JX1991 Un3, 2nd Floor& Offsite Storage). This is also available in HeinOnline’s Foreign & International Law Resources database.
A useful if skimpy, one volume digest of prominent arbitrations is:
- Stuyt, A. M. ed., Survey of international arbitrations, 1794-1989. Dordrecht; Boston: M. Nijhoff Publishers, c1990 (JX1991 St991 1990, 2nd Floor).
Other useful starting points include:
- Office of Legal Affairs, Codification Division, Handbook on the peaceful settlement of disputes between states. New York: United Nations, c1992. (JX1977.P4 H192 1992, 2nd Floor).
- Secretary General and the International Bureau of the Permanent Court of Arbitration, Permanent Court of Arbitration : basic documents. The Hague, Netherlands: The Court, c1998 (JX1925.A2 P422 1998, 2nd Floor).
Arbitration is also the major tool for settlement of disputes between states and large international companies, such as oil or construction companies which contract directly with states or state enterprises. These exist in the misty area between public and private international law.
The ICJ Statute Article 38(1)(d) displays the traditional Civil Law respect for academic writing, rating it an equal source of law to case law, and treating them both as persuasive rather than authoritative evidence of sources of law:
"[J]udicial decisions and the teachings of the most highly qualified publicists of the various nations, as subsidiary means for the determination of rules of law."
Section 103 (2)of the Restatement perhaps changes the emphasis, but still rates secondary material highly by common law standards:
"In determining whether a rule has become international law, substantial weight is accorded to
(a) judgments and opinions of international judicial and arbitral tribunals;
(b) judgments and opinions of national judicial tribunals;
(c) the writings of scholars. . . ."
The reporters' notes to the Restatement states:
1. Writings of international law scholars. The "teachings of the most highly qualified publicists of the various nations" are treated in Article 38(1)(d) of the Statute of International Court of Justice as subsidiary means for the determination of international law. See § 102, Reporters' Note 1. Such writings include treatises and other writings of authors of standing; resolutions of scholarly bodies such as the Institute of International Law (Institut de droit international) and the International Law Association; draft texts and reports of the International Law Commission, and systematic scholarly presentations of international law such as this Restatement. Which publicists are "the most highly qualified" is, of course, not susceptible of conclusive proof, and the authority of writings as evidence of international law differs greatly. The views of the International Law Commission have sometimes been considered especially authoritative."
This means that all classes of secondary material: treatises, monographs, journal articles, governmental reports, etc, can be used to argue the existence of a rule of international law. Which ones are the best tends to be a question of which ones have the best logic and have withstood the test of time. In the periodical literature, for example, good material can be found anywhere, although an assessment of the leading journals would include the American Journal of International Law, the Columbia Journal of Transnational Law, the Harvard International Law Journal, International and Comparative Law Quarterly, Journal du droit international (Clunet), Recueil des Cours, Zeitschrift für ausländisches öffentliches Recht und Völkerrecht, the Yale Journal of International Law, etc.

The "Mixed Journal"
Many European journals focused on international law or a specialty within international law have what I call the "mixed" format. This means they combine straightforward articles ("doctrine", in French) with the publishing of key cases in the field, along with some learned comments on the cases. Sometimes they publish legislation, regulations, and/or treaties as well.
Many American law journals are available on Lexis, Westlaw, and Bloomberg Law as well as HeinOnline. A large number of them are focused purely on international law, although many more may have some relevant articles. HeinOnline is often preferable for article retrieval since it provides an exact replica of the print version rather than the HTML text and therefore meets the Bluebook requirements for citation. Many American law journals on HeinOnline have little to no embargo on availability online after publication. However, many international journals will have indexing only available on HeinOnline for several years after publication, requiring retrieval of the article from another database or from the print edition.
International Organizations have become a major part of international relations, especially since WWII. Over the years they have developed a special status in international law. This is recognized in the Restatement which devotes a section to them including this statement:
§ 223 Subject to the international agreement creating it, an international organization has
(a) status as a legal person, with capacity to own, acquire, and transfer property, to make contracts, to enter into international agreements with states and other international organizations, and to pursue legal remedies; and
(b) rights and duties created by international law or agreement.
Another common term for these groups is Inter-Governmental Organizations (IGOs) which is especially useful to distinguish them from international groups whose members are not governments, such as Greenpeace or the World Council of Churches . Those kinds of groups are known as NGOs, for Non-Governmental Organizations, and they can be very visible in international affairs.
The key thing to remember is that many IGOs have the capacity to create a kind of legislation within their area of competence and if a tribunal or other form of adjudicatory mechanism is part of their structure, to render decisions affecting their members. The biggest IGO is the United Nations. Besides existing for its own purposes, it serves as an "umbrella" organization for many special purpose IGOs such as the Food and Agriculture Organization or the World Health Organization.
The other major class of international organizations is the regional organization. The most visible of these is the European Union, but there many of them, including the Organization of American States(OAS), Mercosur, the Organisation of Islamic Cooperation, the African Union (AU), and the Association of South East Asian Nations (ASEAN). [NB: NAFTA is not an organization.]

The Internet has transformed the struggle to stay ahead of the documentation of IGOs. Most of them now have websites which at a minimum provide descriptive material, while the best of the sites reflect a realization that Internet publication of their materials helps both the organization and the would-be user. The library at Northwestern University has created a research guide with links to a large number of IGO sites.
The United Nations is the biggest and most complicated of the IGOs and acts as the parent organization for many others. A fair amount of the work of the UN has some impact on international law, either developing it, creating it, or enforcing it. To get an overview of the full range of UN activities, take a look at a recent volume of the United Nations Yearbook (JZ4947 .Y43, 4th floor).
Within the United Nations website there is a section which serves as an introduction to the structure and functions of the UN. Most importantly for research purposes, there is a site devoted to the documentation system. Within this page there are quick links to different helpful areas of the UN system including research guides.
The main bodies within the UN are the General Assembly, which has delegates from all the member countries; the Security Council, which has 15 members, 5 permanent and 10 rotating; the Economic and Social Council; and the Secretariat, which supports the work of the Secretary General. On December 22, 2017, the main part of the 72nd session of the General Assembly will close.
The development of the UN websites means that finding some materials has become much easier. For example, General Assembly Resolutions from 1980 and Security Council Resolutions from 1946 on are on the main websites. In some circumstances, the collection of UN documents relating to a particular subject are more comprehensively presented at a site maintained by a subsidiary organization. A good example of this is the site run by the High Commissioner for Human Rights.
The United Nations was developed during the latter part of World War II. It is the heir to the League of Nations, the first attempt at a truly worldwide IGO with a mandate to cover a wide range of subjects.
SUBJECT ORIENTED IGOs
The specialized agencies of the UN serve to coordinate world wide activities in specific subject areas. They are roughly analogous to our domestic federal agencies. For example, the US agency in charge of issues relating to airlines, airports, and air traffic control is the Federal Aviation Administration. The worldwide equivalent is the International Civil Aviation Organization (ICAO). There are many of these IGOs with varying amounts of power and different structures. All are the result of treaties and often serve to coordinate additional treaties in the same area. Most produce some sort of legislation-like texts. Most have some sort of representative body. Some have adjuducative bodies with of limited jurisdiction. All of them produce some sort of documentation.
This documentation includes treaties, meeting records, treaty or regulatory proposals, tribunal decisions, etc. The publishing and distribution structures are not coordinated, so finding the material can be a challenge. The best single guide to most of this is Peter Hajnal's International information: documents, publications, and electronic information of international governmental organizations (JZ4850 .I58 1997, 3rd Floor Reference Collection). This was written just as the Internet was taking off, so there is some acknowledgment of electronic sources, but it is now best seen as a snapshot of the end of the paper period. Virtually all of the UN related IGOs have a website. The UN maintains a central site linking to all UN affiliated groups. You can search through UN resources through the Dag Hammarskjöld Library research guides.
Examples of current IGO websites include:
- Food and Agriculture Organization (FAO)
- International Civil Aviation Organization (ICAO)
- International Labour Organization (ILO)
- International Monetary Fund (IMF)
- World Health Organization (WHO)
- World Intellectual Property Organization (WIPO)
A very detailed research guide to United Nations materials can be found on Globalex.
World Trade Organization (ex-GATT)
The World Trade Organization (WTO) is one of the newer international organizations. It describes itself as "a place where member governments go, to try to sort out the trade problems they face with each other.” The WTO was created in 1995 as the result of what is known as the "Uruguay Round of Negotiations", which lasted from 1986 to 1994. It evolved from the more awkwardly structured General Agreement on Tariffs and Trade (GATT).

From the point of view of the IGO and European Federalists, the European Union is the most successful IGO in existence. "Eurosceptic" politicians would grudgingly agree, but fear it has been too successful. There has been a substantial surrender of portions of normally sovereign power by its members, so EU rules and decisions have a direct effect on the citizens of the member states. It consists of twenty-eight member countries, with several others transposing EU legislation into national law and other potential candidates. Its earliest purposes were economic coordination and development, but there is now a strong social context as well. Besides the main website, there is a site linking the main government websites of the member states.
The rule making and judicial systems of the EU are very complicated, involving the interplay of a very powerful "Commission", the Council of the European Union, and the European Parliament (which would like to be more powerful). The interplay of these bodies is the subject of a very useful webpage.
European Court of Justice (Luxembourg) and related bodies are described above, in the Case Law section.
Council of Europe
The Council of Europe is an intergovernmental organisation which aims:
to protect human rights, pluralist democracy and the rule of law;
to promote awareness and encourage the development of Europe’s cultural identity and diversity;
to seek solutions to problems facing European society (discrimination against minorities,
xenophobia, intolerance, environmental protection, human cloning, Aids, drugs, organised crime, etc.);
to help consolidate democratic stability in Europe by backing political, legislative and constitutional reform.
The Council of Europe covers all major issues facing European society other than defence. Its work programme includes the following fields of activity: human rights, media, legal co-operation, social and economic questions, health, education, culture, heritage, sport, youth, local democracy and transfrontier co-operation, the environment and regional planning.
The Committee of Ministers is the Council of Europe’s decision-making body, and is composed of the Foreign Ministers of the 47 member states (or their Permanent Representatives) and 6 observer states. The Parliamentary Assembly is the Organization’s deliberative body, the members of which are appointed by national parliaments. The Congress of Local and Regional Authorities of Europe is a consultative body representing local and regional authorities.
The main website for this evolving common market of South America provides access in Spanish and Portuguese. There is a multivolume set called Código del MERCOSUR, edited by Roberto Dromi (JX1986 C648 1996, 2nd Floor) which contains a plethora of material including "Tratado, potocolos, acuerdos, declaraciones, decisiones, resolucions", etc.
Comparative Law Basics
I hope it has become clear that in researching international law you may need to work with materials from legal systems other than the United States. Finding applicable cases, statutes, regulations, or treaties may involve working with the domestic law research systems of any number of countries. Besides finding the raw information, such as treaties, it can be important to understand how international law fits into the legal system of a country. It can be dangerous to assume that a treaty is followed in another nation in exactly the same way as the United States, especially if that country’s legal background is substantially different from ours. In practice, lawyers rely on foreign firms to provide them assessments of the issues in this area.
In a gross over-simplification, the three major legal systems of the world are the Common Law System, developed from English sources and dominant in the areas colonized by England, Islamic law, dominant in the Middle East, and the Civil Law System, developed from Roman law and dominant everywhere else. A fourth system, Socialist law, developed in countries with Marxist governments, but it is now generally perceived as an off-shoot of Civil Law, and the ex-socialist countries tend to be re-developing along civil law lines. There are a number of less widely spread systems throughout the world which struggle to survive against the imperialism of the ex-colonial systems.
Some areas, such as Louisiana, Scotland, and South Africa are perceived as "mixed jurisdictions" due to their blending of Civil and Common law influences.
A good introduction to Civilian thinking is John Merryman’s The civil law tradition: an introduction to the legal systems of Western Europe and Latin America (Comp 300 M554 2007, 3rd Floor Reserve). Another work is Peter de Cruz’s Comparative law in a changing world (Comp 300 D359c 2007, Cellar). A good starting point might be an older, non-academic work, The Faces of Justice (Comp 870 B39, Offsite Storage) by Sybille Bedford .
The leading tool for starting comparative law research is Foreign law: current sources of codes and basic legislation in jurisdictions of the world (K38 .R49 1989, 4th Floor) by Tom Reynolds and Arturo A. Flores. This is a multivolume looseleaf annotated bibliography with a section on each country in the world. It is also available as an online database that is now edited by Marci Hoffman.
For a good background presentation for each country and territory in the world, the best paper source is The Statesman's year-book (JA51 .S7, 3rd Floor Reference Collection), which has been published since 1864. However, a faster start might be made through the web version of the CIA guide known as "The World Factbook."
Within general comparative law there is recognition that there is a subject which might be called "comparative international law" The basic works are treatises which expound upon a particular country's application of international law. Examples include:
- Blay, Sam, et al, Public international law: an Australian perspective. Melbourne; New York: Oxford University Press, c1997 (JX2000 P962 1997, 2nd Floor).
- Kindred, Hugh M., International law, chiefly as interpreted and applied in Canada. Toronto : Edmond Montgomery Publications, c2006 (KZ358.A2 I57 2006, 4th Floor).
- Rideau, Joel, Droit international et droit interne francais. Paris: A. Colin, c1971 (JX1248 R43, 2nd Floor).
Or they can come in a larger form:
- Juris-classeur de droit international. Paris: Editions techniques 1955- (Comp 030 J979, Cellar)
Other Useful Websites
- NYU Law School’s Library Guide, "Foreign Databases By Jurisdiction" created by Mirela Roznovschi, covers 64 countries, and includes information on multi-jurisdictional and subject-specific sources as well as constitutions.
- An interesting international database of constitutional texts can be found at the International Constitutional Law Project.
- Globalex also has a number of comparative law research guides that may be of use.
- The Library of Congress has the Guide to Law Online, which provides some information on most countries.
One byproduct of the diffuse nature of the sources of international law is that there is a high level of cooperation among the librarians and other specialists who work in the field.
American Society of International Law (ASIL) Electronic Resource Guide (ERG), works well with ASIL’s Electronic Information System for International Law (EISIL) include information on newsletters, blogs, and other current awareness tools.
Another key networking site is the Jurist site at Pitt Law. It is designed to be a nexus for sharing electronic resources among law professors and can lead to syllabi, course notes, and outlines in areas of interest.
- The Lauterpacht Centre was founded by Sir Elihu Lauterpacht QC in 1983. It is one of the specialist centres of the Faculty of Law at the University of Cambridge. It describes itself as “a forum for the discussion and development of international law. . . .”
- Among other things, this has an on-line catalogue of some depth which is especially useful because it includes articles.
- Le Réseau Internet pour le Droit International", (www.ridi.org)
- "a été créé le 23 octobre 1998 sur une initiative, privée et indépendante, de chercheurs du Centre de droit international de l'Université de Paris 1 Panthéon-Sorbonne en vue de participer au développement et à la diffusion du droit international sur internet." Within this is an interesting site called "Actualité et Droit International, Revue d'analyse juridique de l'actualité internationale."
- Maintained by the arts, business, law, and education librarians at the University of Western Australia, it is basically a HUGE collection of links.
As with anything to do with the web, this section could continue in ever widening spirals of marginal information. I’ll stop it here and hope you get the idea that there is a lot of information "out there."
I’ll also leave you with a major caveat: Not All Websites Are Equal . When you look at information, ask yourself "why is it there?" If the website exists to serve the people who are creating the data, then the texts are likely to be reliable. If the connection between the text and the website is less obvious, the more likely the text may have been sloppily created and is perhaps unreliable. As with thoroughbred racehorses, pedigree is all. Additionally, websites often change their URL so some links may not work; it is always helpful to search for the site to find its new URL.
