Practice Relating to Rule 52. Pillage
Sweden’s IHL Manual (1991) states: “Pillage in connection with the capture of a town or locality is prohibited.” 
Sweden, International Humanitarian Law in Armed Conflict, with reference to the Swedish Total Defence System, Swedish Ministry of Defence, January 1991, Section, p. 52.
In its judgment in the Arklöf case in 2006, Sweden’s Stockholm District Court stated:
Pillage is prohibited according to international law (Geneva Convention IV article 33, Additional Protocol II article 4).
This prohibition has customary status, and [committing pillage] is a serious violation.
