Researching International Law
Judy Gire, Library Director
Sources of International Law
When researching international law issues, Article 38 of the International Court of Justice Statute http://www.icj-cig.org/documents/index.php?p1=4&p2=2&p3=0 lists the sources of international law in order of their weight as authority:
- International conventions and treaties
- International custom as evidence of a general practice accepted as law
- General principles of law recognized by civilized nations (doctrines of fairness and justice applied universally in legal systems throughout the world)
- Judicial decisions and teachings of the most highly qualified publicists
The first three sources are primary sources while judicial decisions and teachings of the most highly qualified publications are treated as secondary sources.

Status of Treaties Where United States is Not a Party
Checking for signatories, status, ratification and reservation information on treaties where the United States is not a party can be difficult. There is no one collection of links providing access to all relevant treaty information. The United Nation’s Status of Multilateral Treaties Deposited with the Secretary-General http://treaties.un.org/Pages/ParticipationStatus.aspx is a good place to start but status information and reservations are limited to a small portion of the world’s treaties. Check databases or web sites provided by treaty secretaries and depositories for regional organizations.
Customary International Law
“Customary international law develops from the practice of States. To international lawyers ‘the practice of states’ means official governmental conduct reflected in a variety of acts, including official statements at international conferences and in diplomatic exchanges, formal instructions to diplomatic agents, national court decisions, legislative measures or other actions taken by governments to deal with matters of international concern.” (Thomas Buergentahl & Sean D. Murphy, Public International Law in a Nutshell 22-23 (4th ed. 2007).
Evidence of a state’s practice is found in: (1) treaties; (2) decisions of national and international courts; (3) national legislation; (4) opinions of national legal advisors; (5) diplomatic correspondence; and (6) practice of international organizations.
Yearbooks of States and Organizations
Yearbooks published by individual countries and by intergovernmental organizations provide a good way to assess information on state practice. They can note important legislation, case law and diplomatic practice involving international law. Check library online catalogs and web sites for countries and IGOs.
