This classic international law casebook has been updated to cover recent case law, including the International Court's Extradite or Prosecute (Belgium v. Senegal) case, and the Supreme Court's decisions in Samantar v. Yousef (on foreign sovereign immunity) and Kiobel v. Royal Dutch Petroleum (on the Alien Tort Statute). With extraordinary range and depth, this casebook probes "hot topics" such as the Syrian civil war, the seizure of pirates, and the ICC's indictments of African leaders, all calculated to provoke engaging classroom discussions. This casebook is designed for introductory and advanced classes, with detailed readings on the structure and actors of international law and on specialized areas.
