Practice Relating to Rule 147. Reprisals against Protected Objects
Section D. Objects indispensable to the survival of the civilian population
Sweden’s IHL Manual (1991), referring to Article 54 of the 1977 Additional Protocol I, provides: “The article also states … that [such property as is essential for the survival of a civilian population] may not be subjected to reprisal attacks.” 
Sweden, International Humanitarian Law in Armed Conflict, with reference to the Swedish Total Defence System, Swedish Ministry of Defence, January 1991, Section § 3.2.1.5, p. 60.
While noting that the Swedish IHL Committee strongly discourages even this possibility in view of its manifestly inhuman effect, the manual 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.
