Practice Relating to Rule 161. International Cooperation in Criminal Proceedings
Section A. Cooperation between States
Côte d’Ivoire’s Teaching Manual (2007) provides in Book III, Volume 2 (Instruction of second-year trainee officers):
II.1. National repression
Grave breaches of international humanitarian law need to be prosecuted not only by the detaining power, but by each State in the power of which the presumed culprit finds himself. One therefore speaks of universal jurisdiction. States must therefore give mutual legal assistance, for example by extraditing an accused if a State renounces criminal prosecution, or by transmitting means of evidence.
