War Crimes in Non-international Armed Conflicts under the Statute of the International Criminal Court

Abstract

International humanitarian law applicable in non-international armed conflicts has long been characterized by the absence of universal competence to suppress serious violations of its provisions. This failure has been due to the reluctance of states – which are naturally prone to consider any limitation of their exclusive competence in this field as a threat to their sovereignty – to criminalize such acts under international law.The first attempt at remedying such a situation was seen in the Draft Statute of an International Criminal Court (ICC), which was prepared by the International Law Commission (ILC) in 1994, and inspired by the draft articles of the Code of Crimes against the Peace and International Security of Mankind, provisionally adopted by the ILC in 1991 at first reading. Under the Draft Statute of the ICC, serious violations of the laws and customs applicable in armed conflicts would be under the jurisdiction of the Court. The ILC had in mind exceptionally serious war crimes, such as those described in the pertinent article of the draft code referred to by the Commission, constituting an extremely grave violation of the principles and laws of international law applicable in armed conflicts. In the commentary on this article, the ILC took care to specify that the expression ‘armed conflict’ covered the non-international armed conflicts that are the focus of common Article 3 of the Geneva Conventions of 12 August 1949, as well as international armed conflicts.This first step was of very limited scope. In fact, according to the ILC, in order to be criminalized, the laws and customs of war had to find their origin in general customary international law.
