Practice Relating to Rule 145. Reprisals
Section B. Reasonable notice and measure of last resort
New Zealand’s Military Manual (1992) states:
(c) There must be reasonable notice that reprisals will be taken. What degree of notice is required will depend on the particular circumstances of each case. Notice is normally given after the violation but may, in appropriate circumstances, predate the violation. An example of notice is an appeal to the transgressor to cease its offending conduct and punish those responsible. Thus, such an appeal may serve both as a plea for compliance and a notice to the adverse Party that reprisals will be undertaken.
(d) The victim of a violation must first exhaust other reasonable means of securing compliance in order to justify taking reprisal.
