Evidence, the Court, and the Nicaragua Case

Abstract

The decision in the Nicaragua case is one of the most important judgments ever delivered by the International Court. It is by far the “heaviest” case, in the parlance of the English barrister, ever decided by the Court in the absence of a party. It has broken new ground for the application of Article 53 of the Statute. It deals in detail with the multilateral treaty reservation of the United States (the “Vandenberg amendment”). It contains provocative reasoning about the genesis and maintenance of rules of customary international law, separate from treaties such as the United Nations Charter. It contains seminal findings on the use of force and the exercise of the inherent right of self-defense under Article 51 of the Charter. It presents fresh and doubtless controversial interpretations of the principle of nonintervention. It prescribes limits to “collective counter-measures” in response to conduct not deemed to amount to “armed attacks.”
