Practice Relating to Rule 69. Loss of Inviolability of Parlementaires
New Zealand’s Military Manual (1992) states:
The parlementaire and those with him are entitled to complete inviolability, so long as they do nothing to abuse this protection or to take advantage of their protected position …
When ordered to withdraw, the parlementaire must be given a reasonable time in which to do so. If he fails to withdraw, he loses his inviolability and may be fired upon.
