II. INTERNATIONAL COURT OF JUSTICE: QUESTIONS RELATING TO THE OBLIGATION TO EXTRADITE OR PROSECUTE (BELGIUM v SENEGAL) JUDGMENT OF 20 JULY 2012

Abstract

This case1 marks the first pronouncement by the International Court of Justice (ICJ) on the obligation to extradite or prosecute (aut dedere aut judicare) in international law. It is the second contentious case in which the ICJ has held the defendant country in breach of its obligations under a human rights convention. The ICJ both added to the corpus of norms it has formally recognized as peremptory norms (jus cogens) and also reinforced the principle that former heads of state are subject to universal jurisdiction for grave violations of international law.
