Practice Relating to Rule 160. Statutes of Limitation
Cameroon’s Instructor’s Manual (2006) states:
Statutes of Limitations
Even though the Geneva Conventions and their Additional Protocols do not specifically address statutes of limitations, it is accepted today on the basis of customary law that all international crimes (the crime of genocide, crimes against humanity [and] war crimes) are not subject to statutes of limitations.
