International criminal law is a body of international law designed to prohibit certain categories of conduct commonly viewed as serious atrocities and to make perpetrators of such conduct criminally accountable. Principally, it deals with genocide, war crimes, crimes against humanity, as well as the war of aggression. "Classical" international law governs the relationships, rights, and responsibilities of States, and, conversely, criminal law generally deals with prohibitions addressed to individuals. Penal sanctions for violation of those prohibitions are imposed by individual States. International criminal law comprises elements of both - although its sources are those of international law, its consequences are penal sanctions imposed on individuals. In this collection, all major regulations related to international criminal law are presented. The focus is not only on documents related to the International Criminal Court, ad hoc tribunals, and international operating courts, but the book also contains more practical national and regional regulations.
