This book provides practitioners with a ready and comprehensive reference to the procedures for the enforcement of competition law in the UK following the implementation of the EC modernisation regulation (European Council Regulation 1 of 2003). The modernisation regulation came into effect on 1 May 2004, along with substantial changes to the Competition Act 1998 in the UK. As former Office of Fair Trading officials who were closely involved in the UK implementation of the EC modernisation regulation, the authors have first hand knowledge of the procedural changes in the UK and in Europe. They draw upon this experience, as well as the expertise of the Editor and Consultant Editor, in providing a truly practical and invaluable analysis of the modernised regime. This book essentially covers practice and procedure, while also providing a brief overview of the substantive elements of competition law (which have not changed). It provides comprehensive and up to date coverage of the competition law procedures relevant to businesses and lawyers in the UK today. The book is edited by Margaret Bloom (King's College, London), a well known and respected leader in the field of UK competition practice, and Anneli Howard, a barrister at Monckton Chambers specialising in competition law.
