Practice Relating to Rule 147. Reprisals against Protected Objects
Section E. Natural environment
Sweden’s IHL Manual (1991), while noting that the Swedish IHL Committee strongly discourages even this possibility in view of its manifestly inhuman effect, states:
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.
