With the rising relevance of international organizations in international affairs, and the general turn to litigation to settle disputes, international institutional law issues have increasingly become the subject of litigation, before both international and domestic courts. The judicial treatment of this field of international law is addressed in Judicial Decisions on the Law of International Organizations through commentary on excerpts of the most prominent international and domestic judicial decisions that are relevant to the law of international organizations, providing in-depth analysis of judicial decisions. The commentaries written and edited by leading experts in the field of international institutional law, they are opinionated and critically engage with the decision in question, with commentators’ and stakeholders’ reactions thereto, and with later decisions, codifications, and reports.
