Practice Relating to Rule 145. Reprisals
Section E. Termination of reprisals as soon as the adversary complies again with the law
The US Naval Handbook (1995) states: “To be valid, a reprisal action must conform to the following criteria: … 7. A reprisal action must cease as soon as the enemy is induced to desist from its unlawful activities and to comply with the law of armed conflict.”
The Annotated Supplement to the US Naval Handbook (1997), with reference to the rule that a reprisal must cease as soon as the enemy is induced to desist from its unlawful activities, states:
When, for example, one party to an armed conflict commits a breach of law but follows that violation with an expression of regret and promise that it will not be repeated, then any action taken by another party to “right” the situation cannot be justified as a lawful reprisal.
The US Naval Handbook (2007) states: “To be valid, a reprisal action must conform to the following criteria: … 7. A reprisal action must cease as soon as the enemy is induced to stop its unlawful activities and to comply with the law of armed conflict.”
