This book examines one of the most important challenges facing the United Nations today: the effective and lawful use of force by or under the authority of the UN to maintain or restore peace. In particular, the book provides a legal analysis of the institutional mechanisms and processes which the UN employs to use force to maintain or restore peace. The UN Security Council is the main organ of the UN entrusted with the responsibility for the
maintenance or restoration of peace. It is given broad powers of enforcement under Chapter VII of the UN Charter in order to achieve this objective. However, the Charter provision which was intended to
provide the Council with a standing military force to carry out enforcement action has not as yet been implemented. In response, the Council has sought to deal with an increasing demand for military enforcement action by delegating its powers in this area to other UN organs (e.g. the UN Secretary-General in Somalia, and the War Crimes Tribunals for Rwanda and the former Yugoslavia), UN Member States (e.g. the coalition against Iraq), and regional and collective self-defence organizations (e.g.
NATO in Bosnia). It is this process of delegation of military enforcement powers by the Council which is the focus of the book. By examining the legal framework which governs the process of a
delegation by the Council of its Chapter VII powers; the practice relating to the exercise of these powers by each of the delegates concerned; and the policy issues relating to such delegations, the book makes a significant contribution to the content of the law pertaining to the use of force by the UN and provides guidance as to the likely future developments in the legal framework governing collective action to maintain peace under the auspices of the United Nations.
