International Criminal Law (Introduction)

International criminal law is the part of public international law that deals with the criminal responsibility of individuals for international crimes. There is no generally accepted definition of international crimes. A distinction can be made between international crimes which are based on international customary law and therefore apply universally and crimes resulting from specific treaties which criminalize certain conduct and require the contracting states to implement legislation for the criminal prosecution of this conduct in their domestic legal system. The international core crimes, i.e., crimes over which international tribunals have been given jurisdiction under international law, are: genocide, war crimes, crimes against humanity, and aggression. International criminal law finds its origin in both international law and criminal law and closely relates to other areas of international law. The most important areas are human rights law and international humanitarian law as well as the law on state responsibility. The sources of international criminal law are the same as those of general international law mentioned in article 38(1) of the Statute of the International Court of Justice: treaties, international customary law, general principles of law, judicial decisions and writings of eminent legal scholars. The Nuremberg and Tokyo trials signaled the birth of present-day international criminal law, i.e., the prosecution of individuals for international crimes before international tribunals. In the early nineties of the previous century international criminal law received a major stimulus with the establishment of the International Criminal Tribunal for the former Yugoslavia and the International Criminal Tribunal for Rwanda by the United Nations Security Council. Also the creation of various internationalized or mixed criminal courts and the proposals of the International Law Commission, which resulted in the creation of the International Criminal Court in 2002, contributed to the rapid development of international criminal law during the last two decades.
