Practice Relating to Rule 67. Inviolability of Parlementaires
The Military Manual (1993) of the Netherlands states:
A parlementaire has the right to inviolability … [The white flag] indicates that the party who displays the flag wants to negotiate. This party must cease fire. The other party has no obligation to cease fire. However, the parlementaire and any person who may accompany him (e.g. an interpreter) may not be fired upon.
