The Conduct of Hostilities, Attack Effects, and Criminal Accountability

Abstract

War crimes related to the decision to carry out attacks during the conduct of hostilities are almost always defined in terms of conduct and not result (Article 8(2)(b) of the Rome Statute of the International Criminal Court). Yet it is common for critiques of such decisions to focus on attack results as proof of their alleged illegality. While such results are probative of compliance or non-compliance with international humanitarian law rules regulating the conduct of hostilities, they should rarely be indisputable. This article addresses the challenge of attaching probative value to attack results when assessing responsibility for alleged war crimes based on allegedly illicit attack decisions.
