Practice Relating to Rule 157. Jurisdiction over War Crimes
In its Decision No. 53/1993, the Constitutional Court of Hungary stated:
A defining characteristic of war crimes and crimes against humanity is that they are punished irrespective whether or not they violated the laws of the country in which they were committed … [W]hether the proclamation of the Geneva Conventions has properly taken place is of no moment, nor whether the obligation assumed by the Hungarian state to implement them had occurred prior to the date designated by the Law as the temporal limit of its scope (October 23, 1956, that is). The criminal liability of the commissioners remains by international law and subsequent domestic legislation may give effect to the full scope of liability.
