Yugoslavia, Federal Republic of
Practice Relating to Rule 161. International Cooperation in Criminal Proceedings
Section E. Cooperation with international criminal tribunals
The Report on the Practice of the Federal Republic of Yugoslavia (FRY) notes:
In fact, the refusal to amend Article 17 of the FRY Constitution prohibiting extradition of own nationals, or to apply somewhat broader interpretation of its provisions, is an expression of the lack of political will to accept jurisdiction of the [ICTY] and, therefore, a sign of rejection of the obligation to recognise universal jurisdiction based on the Tribunal Statute. This position is clear from numerous statements regarding the calls to the FRY to extradite its nationals indicted by the Prosecutor of the Tribunal for war crimes.
