Yugoslavia, Federal Republic of
Practice relating to Rule 66. Non-Hostile Contacts between the Parties to the Conflict
The Report on the Practice of the Federal Republic of Yugoslavia notes that, during the conflicts in the former Yugoslavia, there were no large military operations in Slovenia that could have triggered negotiations with the enemy on the battlefield and that “it is hardly realistic that traditional requirements of the international law of warfare would have been respected” in the conflict in Croatia. The report concludes that the opinio juris of the Federal Republic of Yugoslavia “is, beyond any doubt, that a legal possibility exists to contact the enemy on the battlefield”.
