International Law: Evolving Doctrine and Practice offers a flexible arrangement of materials for the teaching of an introductory course in international law. The inspiration for the book's editorial approach is the recognition that each professor comes to the study of international law from a variety of normative, critical, or interdisciplinary perspectives, and that the materials should be flexible enough to accommodate all comers. With this goal of pedagogical ecumenism in mind, the chapters present a variety of critical approaches to international law without letting one particular view dominate, though taken together the materials highlight the evolving nature of international legal doctrine and those areas where its legal norms remain contested or controversial. Sprinkled through each chapter are short Problem Cases—less than a page in length—that give students the opportunity to apply the doctrine to a unique fact pattern. The Problem Cases are presented in modular text boxes that can form the basis for rich classroom discussions or simply reserved for background reading at home, whichever the professor wishes. In addition to the typical array of chapters on sources and subjects of international law, human rights, International Humanitarian Law, International Criminal Law, the use of force, and humanitarian intervention, the book also includes chapters on international economic law and environmental law, including a consideration of the challenge posed by climate change.
