War Crimes Involving Autonomous Weapons: Responsibility, Liability and Accountability.

This article identifies and evaluates key international legal aspects concerning three notions that have figured in debates on war crimes involving an autonomous weapon system (AWS): responsibility, liability and accountability. It focuses on the general contours of the existing international law of armed conflict, also known as international humanitarian law (IHL), and related fields, concepts and institutions. Regarding responsibility, this article examines, on one hand, the international responsibility of a state for an internationally wrongful act related to a breach of a rule of IHL involving an AWS that may form the basis of a war crime and, on the other hand, individual criminal responsibility for a war crime involving an AWS. As for liability, this article outlines three international legal concepts of state liability potentially related to a war crime involving an AWS. Finally, this article sets out an, at least, legally adjacent concept of accountability that involves an explanation of the conduct related to a war crime involving an AWS and imposing political, legal, social or other consequences where such an explanation is absent or insufficient.
