jats:pThe International Court of Justice (Court or ICJ) delivered three judgments in 2015. The first, delivered on February 3, 2015, determines claims of genocide made by Croatia and Serbia against each other. The second, delivered on September 24, 2015, addresses Chile’s preliminary objection in a case brought against it by Bolivia, which asserted that Chile had violated its obligation to negotiate in good faith to secure Bolivia’s sovereign access to the Pacific Ocean. The third, delivered on December 16, 2015, concerns the joined cases brought by Costa Rica and Nicaragua, each party alleging territorial violations and transboundary environmental harms by the other. This review highlights notable points of interest in the judgments and draws attention to particular insights and critiques afforded by the individual opinions that accompany each judgment.</jats:p>
