Janis, Noyes, and Sadat on International Law presents this complex subject in an authoritative and well-written casebook. The book introduces the history and nature of international law and its sources—treaties, custom, general principles, jus cogens, and equity. It explains how international law is applied in U.S. courts and in international arbitration and adjudication. The book addresses many of the key settings in which international law plays a critical role: international human rights, the recognition and succession of states and governments, international and non-governmental organizations, war and peace, the law of the sea, and inter-state judicial relations. The book's materials, largely domestic and international judicial decisions, are both sophisticated and teachable, the perfect introductory casebook for any U.S. law school.

—Mark Drumbl, Class of 1975 Alumni Professor of Law; Director, Transnational Law Institute; Washington and Lee University

“The publication of the 6th edition of International Law, by Janis, Noyes, and welcome new co-author, Leila Sadat, could not be more timely. Its stunning photographs, plentiful maps, and up-to-the-minute new material transforms what has long been a leading text into an indispensable one. It is a beautiful, lively, and rigorous book and a powerful way to introduce students to a new era in international law.”
—Barbara Stark, Professor of Law and Hofstra Research Fellow, Maurice A. Deane School of Law, Hofstra University

“I have been using this textbook for at least 10 years. It is concise, with helpful notes that help students focus their attention on what is really relevant in the materials before them. The authors also put cases in a wider and/or historical context. As an African American professor this does some of the heavy lifting for me. Finally, the authors really try to use documents rather than articles on the topic. Thus the inclusion of actual treaties rather than article on Treaties. I could go on. And on.”
—Ruth Gordon, Professor of Law, Villanova University, Charles Widger School of Law
