This is the second edition of a key analytical commentary on the competition procedures of the EC, written by a distinguished editor and contributor team with extensive experience in the area. It provides the reader with an exhaustive account of the relevant rules, which includes a completely revised and updated analysis of antitrust procedure in the wake of the modernization of EU competition law. The reader is given a detailed discussion of the Commission's package of regulations and guidelines and their interaction in practice, in a field where new rules have caused a major change and the need for practitioners to reorientate themselves. The section on antitrust rules will be complemented by new sections on procedures for public undertakings, merger control, and state aid. As a practical guide to procedure it focuses upon the implementation of the regulatory framework by the Commission and the relevant case law of the European Courts. It will prove an indispensable source of guidance for all practitioners involved in competition proceedings before the European Commission and national competition authorities.
