This book presents an integrated approach to general questions of European administrative law and offers some possible solutions to the problems which it poses, the Treaty establishing a Constitution for Europe being the point of reference. Under the Treaty general questions of administrative law are no longer addressed merely in a fragmented or incidental way but as a discipline that governs the exercise of sovereign powers by a supranational entity. This calls for a detailed examination of the fields which comprise European administrative law and the book therefore examines in some detail the key areas of rulemaking powers and normative instruments, the implications of the Charter of Fundamental Rights for European and national administrations, administrative procedure, and judicial protection within the European Union. The Foreword to the book is written by Professor Carol Harlow.
