This handbook offers detailed descriptions of EU competition law, including mergers and public authorities. Above all, it analyzes and discusses recent decisions of the ECJ and the General Court. Presenting systematically structured and theoretically founded content, the book also includes recommendations for practitioners. Special attention is paid to the scope of penalties and the influence on fundamental rights. Rounding out the book, the conflict between safeguarding confidential information and the effectiveness of private and public enforcement is discussed intensively in the context of the new Directive 2014/104/EU.
