The United Nations Claims Commission (UNCC) was set up by the UN Security Council to process claims submitted by victims of the war between Iraq and the Coalition Forces (1990–1991). From an institutional point of view, the UNCC is a curious creation, assuming the form of a hybrid between an administrative claims procedure and an international tribunal. This article will highlight some of the difficulties with the institutional model chosen and focus on the institutional, as well as the normative legitimacy of the UNCC, whereby particular attention is devoted to Iraq's participation in the procedure.
