Since the second edition of this commentary on the Charter of the United Nations was published, the text of the Charter may not have changed but the world has. The wars in Iraq and Afghanistan have had a lasting impact on international law and the Commentary has been fully updated to take their impact into account. The new edition has been completely revised and features a completely new chapter on UN reform, analyzing the effect of reforms which have already beenimplemented and examining why other proposals for reform have failed. It will assess how these proposals could be improved, with a particular focus on the Security Council.

Written by a team of distinguished scholars and practitioners, this book combines academic research with the insights of practice, and is an indispensable work of reference for all those interested in the UN.The Commentary will be crucial in providing new directions for the development of international law and the United Nations in thetwenty-first century.
