This book examines the European Commission's dawn raid practices in competition cases from a fundamental rights perspective. In recent years, the Commission has adopted a new and more aggressive enforcement policy, amid a growing awareness that abuse of market power represents an economic harm and needs to be punished. In response, enforcement has been strengthened by the grant of more wide-reaching powers to competition authorities. But how does this impact on the framework of fundamental rights? This study seeks to answer that question by examining the obligations imposed by the Charter and the ECHR and the response of the Luxembourg and Strasbourg Court. It shows that where the Strasbourg Court has managed to strike a balance between efficiency concerns and the rights of undertaking, the EU courts' judicial control has to date proved to be ineffective. This book is an important and timely examination of this important question. Revised Dissertation.
