Practice Relating to Rule 68. Precautions while Receiving Parlementaires
Section B. Detention of parlementaires
The Socialist Federal Republic of Yugoslavia’s Military Manual (1988) provides:
A parlementaire or the persons escorting him can be temporarily detained if they have seen, without abusing the mission of parlementaire, something or collected information that could cause damage to the party receiving the parlementaire or if they could discover the movement of troops during return.
The parlementaire and his escort will be detained only as long as that information could cause damage to the side that received them.
