International Law Classes 2 & 3: Sources of International Law

In this class, we learn about the major sources of international law, including international custom, treaties, and general principles of law. The first part of the class will consist of a lecture/discussion of the readings from the Crawford textbook (pp. 20-47). In the second part of class, we will then apply these concepts through a discussion problem concerning the customary law of armed conflict. Before you read the study problem and other materials in the playlist for Class 2, you should read Crawford, pp. 20-47. Then read the study problem. Following the instructions in the study problem, you should use the materials in the playlist to prepare to argue either the U.S. government's position or the International Committee of the Red Cross (ICRC) position with respect to the either the customary international law norm concerning protection of humanitarian relief personnel (Rule 31) or causing serious damage to the natural environment (Rule 45). You should read the problem and prepare your thoughts in advance of class 2; however, you will be given additional time during class to work with a small group of classmates to refine your arguments (and ask questions of the professor) before being asked to share your group's arguments with the entire class in the next session. You do not need to read every source in the playlist; the primary sources are there for your use in building your arguments for use in the discussion problem.
