This book aims to evaluate the contribution of Latin America to the development of international law at the International Court of Justice (ICJ). This contemporary approach to international adjudication includes the historical contribution of the region to the development of international law through the emergence of international jurisdictions, as well as the procedural and material contribution of the cases submitted by or against Latin American states to the ICJ to the development of international law. The project then conceives international jurisdictions from a multifunctional perspective, which encompasses the Court as both an instrument of the parties and an organ of a value-based international community. This shows how Latin American states have become increasingly committed to the peaceful settlement of disputes and to the promotion of international law through adjudication. It culminates with an expansion of the traditional understanding of the function of the ICJ by Latin American states, including an analysis of existing challenges in the region.
