In its judgment of 3 February 2003, the International Court of Justice (ICJ) declared the application submitted by the Federal Republic of Yugoslavia (FRY) for revision of its 1996 judgment concerning the Application of the Convention on the Prevention and Punishment of the Crime of Genocide, inadmissible.1 The Court found that the request for revision was not based on the ‘discovery’ of a ‘fact’ and, therefore, one of the conditions of Article 61 of the Statute of the Court was not satisfied. This commentary will appraise the decision by examining the formal and substantive criteria for revision, a rather neglected and underused process.2
