This book investigates how domestic courts interpret and apply the privileges and immunities granted to international organizations within their national legal systems. August Reinisch, a scholar of international law, utilizes a comprehensive empirical analysis of case law to examine the consistency and divergence of judicial decisions across various jurisdictions. The work argues that while international organizations rely on specific legal protections, the practical application of these immunities remains subject to the varying interpretations of national judges.

Legal scholars and practitioners frequently cite this work as a primary resource for understanding the intersection of domestic litigation and international institutional law. Experts highlight the text for its rigorous methodology and its utility in clarifying the often complex relationship between sovereign courts and international entities.
