Practice Relating to Rule 161. International Cooperation in Criminal Proceedings
Section E. Cooperation with international criminal tribunals
Hungary’s Law on Cooperation with the ICTY (1996) reads:
The Parliament creates the following Act on the fulfilment of obligations deriving from the Statute of the International Tribunal established by Resolution 827 (1993) of the United Nations Security Council for the prosecution of persons responsible for serious violations of international humanitarian law committed in the territory of the former Yugoslavia since 1991 (hereinafter referred to as “the International Tribunal”). 
Hungary, Law on Cooperation with the ICTY, 1996, preamble.
In 1997, during plenary discussions in the UN General Assembly on a report of the International Criminal Tribunal for the former Yugoslavia (ICTY), Hungary deplored “the absence of cooperation with the [ICTY] by certain countries and entities” and called upon all members of the international community and all international forums “to continue to support the Tribunal’s work and to facilitate the fulfilment of its mandate”.
