Practice Relating to Rule 145. Reprisals
Section A. Definition and purpose of reprisals
Sweden’s IHL Manual (1991) states:
Reprisals very seldom achieve their intended aim – the return of a wrongdoer to compliance with international law. In most cases, use of reprisals has, instead, led to a serious increase of suffering and losses among civilians. For these reasons, Sweden has, during the [CDDH] and elsewhere, worked for a strict limitation to the right to reprisal. Under Additional Protocol I, reprisals are permitted only against military personnel. A state acceding to Additional Protocol I thereby accepts a limitation of its freedom to employ reprisals. The [Swedish International Humanitarian Law] Committee believes that this involves a considerable humanitarian advance.
