Practice Relating to Rule 161. International Cooperation in Criminal Proceedings
Section A. Cooperation between States
The Military Manual (1993) of the Netherlands states: “in general, States are obliged to provide judicial assistance to each other to the maximum extent possible with respect to penal procedures concerning grave breaches”. 
Netherlands, Toepassing Humanitair Oorlogsrecht, Voorschift No. 27-412/1, Koninklijke Landmacht, Ministerie van Defensie, 1993, p. IX-8.
The Military Manual (2005) of the Netherlands provides:
The universality principle is closely linked to the rule on the transfer of persons suspected of having committed or ordered a war crime. Generally, States are bound to grant each other as much mutual assistance as possible in matters of criminal procedures relating to serious violations. They must cooperate as much as possible in handing over war criminals.
