International criminal law (ICL)

International criminal law (ICL) codifies a body of law that defines international crimes such as genocide, war crimes, crimes against humanity, and the crime of aggression, as well as the procedures to be applied before international courts and tribunals. These crimes often take place in the course of conflict, and hence relate directly to humanitarian crisis. In contrast to much international law, ICL does not focus on the conduct of States – it establishes individual criminal responsibility. One of the main sources of ICL is the Rome Statute creating the International Criminal Court (ICC).
