The World Court and Jus Cogens

In the merits phase of decision in the case brought by Nicaragua against the United States, the World Court briefly mentions references by states or publicists to the concept of jus cogens . These expressions are used to buttress the Court’s conclusion that the principle prohibiting the use of force found in Article 2(4) of the United Nations Charter is also a rule of customary international law.
