Concomitant Prohibitions: Collective Punishment as the Origin of Other Violations of the Rights of Civilians under Belligerent Occupation

International humanitarian law (IHL) categorically prohibits all types of collective punishment. However, neither treaty nor customary sources provide a clear definition of what should be deemed a collective punishment. Given this lack of clarity, it is no surprise that little attention has been paid to the way in which resorting to different forms of collective punishment during a belligerent occupation might lead to additional violations of international law, including IHL and international human rights law (IHRL). This article explores the notion of collective punishment under the law of occupation and connects it with other relevant rules of international law. Based on this analysis, and using the Occupied Palestinian Territory as a case study, the article argues that violating the prohibition of collective punishment in a situation of belligerent occupation in all likelihood will trigger the breach of other concomitant rules of IHL and IHRL, thus shedding light on the scope of the prohibition contained in Article 33 of the Fourth Geneva Convention.
