The International Criminal Court prosecutes four core crimes and complements national courts

Standing background to separate the ICC from the ICJ. The ICC has its permanent premises in The Hague, Netherlands. The Rome Statute gives it four main crimes: genocide, crimes against humanity, war crimes and the crime of aggression. It acts on the principle of complementarity: it is meant to complement, not to replace, national criminal systems, and prosecutes only when States are unwilling or unable to do so genuinely. The ICJ, by contrast, settles disputes between States.

Core crimes: four Governing treaty: Rome Statute Seat: The Hague, Netherlands
