The fifth edition of this widely used textbook combines narrative explanatory sections that set forth the basic law together with cases, treaties, international documents, questions and problems. Epps focuses on the central problems of international law and how it operates and encourages students to work through a number of questions and problems that are presented in a variety of international contexts. The book's coverage is comprehensive, including recent materials and cases on sources, treaties, jurisdiction, immunities, extradition, the law of the sea, environmental law, international courts and tribunals, the status of international entities, human rights, international criminal law, terrorism, and the laws of war. There is also a set of power point slides to accompany the text distributed free to any faculty member who adopts the book for a course. Faculty will find that the questions posed after every case, or other materials, provide a very useful template for getting students to focus on the essential meaning and implications of the cases and materials. The problems are designed to test students¿ abilities to combine what they have learned throughout a chapter to come up with a comprehensive answer.
