In May 1993, the United Nations Security Council, acting under Chapter VII of the United Nations Charter, passed resolution 827 and established an International Criminal Tribunal for the former Yugoslavia (ICTY). This tribunal, created in response to the threat to peace and security posed by the Yugoslav conflict, sought to bring those people who had violated international law to justice. The court's subject matter jurisdiction includes grave breaches of the Geneva Conventions of 1949, violations of the laws or customs of war, genocide, and crimes against humanity that have occurred within Yugoslavia since 1991. The ICTY, which sits in The Hague, uses English and French as official languages and has primacy over domestic tribunals. This means that the court with the ultimate authority for trying people for war crimes and crimes against humanity is separate-in geography and language-from the country where the atrocities were committed. Because of the invocation of Chapter VII, the ICTY's decisions are binding on all U.N. member states.
