Practice Relating to Rule 68. Precautions while Receiving Parlementaires
Section B. Detention of parlementaires
New Zealand’s Military Manual (1992) states:
If the parlementaire
stays within enemy lines after being ordered to withdraw he loses his inviolability and may be made a prisoner of war. He may similarly be detained and tried if there is prima facie evidence that he has abused his position as a parlementaire, for example by collecting information surreptitiously. It is not an abuse of his position for the parlementaire to report back anything he may have observed.
