In Gulf War Reparations and the UN Compensation Commission: Environmental Liability, experts who held leadership positions and worked directly with the UNCC draw on their experience with the institution and provide a comprehensive view of the United Nations Compensation Comission and its work in the aftermath of the Gulf War. In this volume, the first of two on the UNCCs work, the authors explain that the United Nations Security Council established the ad hoc compensation commission to address reparations as a component of the ceasefire following Iraqs 1990-91 invasion and occupation of Kuwait. The authors also describe how the work of the United Nations Compensation Commission addressed important questions of state responsibility, environmental liability, mass claims processing, international law, and dispute settlement institutions in the post-armed conflict context. Readers will also learn that the scope and the scale of the UNCC was extraordinary, since almost 2.7 million claims from 80-plus countries were submitted to the Commission (which awarded in excess of $55 billion and has paid out more than half of that total), and that this led to the development of innovative procedural, institutional and managerial approaches in handling mass, environmental, and corporate claims at a scale that is unparalleled. Additionally, the books note that the Commission also contributed to the evolution of international jurisprudence in these areas.
