This casebook investigates the mechanisms and patterns by which domestic courts interpret and apply international law within their national legal systems. The authors, a team of distinguished legal scholars led by André Nollkaemper, utilize the extensive data from the Oxford International Law in Domestic Courts (ILDC) database to provide a structured analysis. By curating a selection of significant judicial decisions, the text establishes a framework for understanding the interaction between global legal norms and local judicial practice.

Legal scholars and practitioners frequently cite this work as a primary resource for navigating the complexities of domestic judicial application of international law. Experts highlight the text for its clear synthesis of dense case law, making it a foundational reference for students and researchers in the field.
