For students taking public international law or human rights courses, the following new, free database from the American Society of International Law (ASIL) should be of interest: i.lex (Legal Research System for International Law in U.S. Courts).
Here is the description of the database from ASIL’s Web site:
This online database of select U.S. court cases and related materials is designed to serve as a practical resource for members of the judiciary and other legal professionals to identify and understand how international law is interpreted and applied by U.S. courts at both the federal and state level.
i.lex is not intended to serve as a comprehensive source of case law incorporating international law into the U.S. legal system. Rather, it offers users access to the most important cases involving particular areas of international law such as human rights, refugee and asylum law, diplomatic and consular relations, transportation and communication, trade and transactions, and more.
i.lex provides pdf versions of the opinions, as well as case summaries and brief anaylsis of a decision’s significance. One can search by keyword, topic, treaty or statute. The database includes both state and federal cases.
