This chapter deals with the way in which infringements of Articles 101 and 102 TFEU and Chapter I and II Prohibitions of the Competition Act 1998 are investigated and attacked. The European Commission has its own powers to investigate infringements of EU competition law by virtue of Regulation 1/2003. It may cooperate with national competition authorities (NCAs), who also have their own powers by virtue of EU law and their respective national competition laws. NCAs and the European Commission cooperate through the European Competition Network (ECN). The European Commission and the Competition Markets Authority (CMA) may obtain information, or may investigate on-site. The CMA also has criminal jurisdiction in some cases. Undertakings subject to investigation have rights that must be observed.
