Practice Relating to Rule 67. Inviolability of Parlementaires
Germany’s Military Manual (1992) provides:
Parlementaires and the persons accompanying them, e.g. drivers and interpreters, have a right to inviolability …
When entering the territory of the adversary, parlementaires and the persons accompanying them shall not be taken prisoner or detained. The principle of inviolability shall apply until they have safely returned to friendly territory. It does not require the adverse party to completely cease fire in a sector where a parlementaire arrives.
