This document discusses jurisdiction and admissibility of cases to the International Criminal Court (ICC). It provides details on the ICC's jurisdiction according to temporal, personal, territorial and subject-matter components. Crimes under the ICC's jurisdiction include genocide, crimes against humanity, war crimes, and the crime of aggression. For a case to be admissible, the domestic court must be unable or unwilling to prosecute. The ICC can only hear a case if states are unable or unwilling to act, or if referred by the UN Security Council. It cannot hear cases that states have decided to prosecute domestically.
