International Criminal Law

Body of laws, norms, and rules governing international crimes and their repression, as well as rules addressing conflict and cooperation between national criminal law systems. The term international criminal law refers variously to at least three distinct areas: cooperation between different national legal systems through extradition and other forms of mutual legal assistance; the prohibition and punishment of certain behaviour by several countries acting collectively or by the international community as a whole; and the operation of autonomous international legal systems, including courts and other mechanisms of enforcement, that exist alongside national criminal law.
