Convention pour la prévention et la répression du crime de génocide
The International Court of Justice (ICJ) is the principal judicial organ of the United Nations. It can hear two types of cases: contentious and advisory. Contentious cases are legal disputes between states which can "only" be brought by states. The only mass atrocity crime that the ICJ has jurisdiction over is genocide. Its jurisdiction was established explicitly in the Genocide Convention. Unlike the tribunals discussed above, the ICJ cannot determine individual criminal responsibility. It can clarify and interpret the Genocide Convention as well as hold states accountable for the commission or the failure to prevent or punish genocide.
