Ohlin’s casebook is designed to offer a comprehensive treatment of public international law suitable for a one-semester, three-credit introduction to international law—by far the most popular format for teaching international law at a U.S. law school.

Important features include:

  • A clear explanation of how the methodology and doctrine of international is different from domestic law.
  • Each chapter begins with a clear explanation of the legal doctrine and precisely highlights the areas where that doctrine is unsettled or contested.
  • Each chapter ends with a conclusion that recaps the main points from the chapter. These bullet points also function as de facto learning objectives for each chapter so that students can assess whether they have mastered the key concepts in that area.
  • Each chapter includes modular Problem Cases in shaded boxes which encourage students to apply the learned doctrine to contemporary controversies. The modular nature of these boxes gives the instructor the freedom to focus on, or skip, these Problem Cases.
The third edition features discussion of new cases and events, including the following:
  • New section on erga omnes standing before the international court of justice, including excerpts from The Gambia v. Myanmar and Ukraine v. Russia, as well as a discussion of why jurisdiction was found in the first but not the second
  • Advisory Opinion on Climate Change from the International Tribunal on the Law of the Sea.
  • Expanded materials on the law of occupation and its relationship to the prohibition on annexation, including excerpt from ICJ Advisory Opinion on Legal Consequences arising from the Policies and Practices of Israel in the Occupied Palestinian Territory, including East Jerusalem
  • Materials on the destruction of cultural property as a war crime
