Practice Relating to Rule 161. International Cooperation in Criminal Proceedings
In 1997, during plenary discussions in the UN General Assembly on a report of the International Criminal Tribunal for the former Yugoslavia (ICTY), Costa Rica stated:
The lack of cooperation [with the ICTY] on the part of some Governments and local authorities, in violation of their international obligations, is scandalous. The authorities of the Republika Srpska, the Federation of Bosnia and Herzegovina and the Federal Republic of Yugoslavia (Serbia and Montenegro) must comply with their international obligations. The authorities of these entities must arrest and transfer to the custody of the Tribunal the accused who are in their territories. These authorities must also cooperate in the gathering of evidence and facilitate the participation of witnesses.
