This book offers a comprehensive argument for why pre-existing international law on cluster munitions was inadequate to deal with the full scope of humanitarian consequences associated with their use. The book undertakes an interdisciplinary legal analysis of restraints and prohibitions on the use of cluster munitions under international humanitarian law, human rights law, and international criminal law, as well as in relation to the recently adopted Convention on Cluster Munitions (CCM). The book goes on to offer an in-depth substantive and procedural analysis of the negotiations which led to the 2008 CCM, in part based on the author's experiences as an adviser to Cluster Munitions Coalition-Austria. Cluster Munitions and International Law is essential reading for practitioners and scholars of International Law, including International Humanitarian, Human Rights, International Criminal or Disarmament Law and anyone interested in legal and humanitarian perspectives on cluster munitions legislation and policy. It is unique in bringing a practitioner's perspective to a scholarly work.
