An inverse analysis of the digital markets act: applying the Ne bis in idem principle to enforcement

Abstract

ABSTRACT On 18 July 2022, the Council gave its final approval of the Digital Market Act’s final text. Notwithstanding the amendments following the initial proposal published by the European Commission on 15 December 2020, the main objectives of the DMA have remained untouched and separate from the objectives pursued by competition rules. In the interim, the Court of Justice of the European Union (CJEU) issued its preliminary rulings on the bpost and Nordzucker cases, with particularly relevant consequences concerning the application of the double jeopardy principle. The potential remedies and obligations imposed on the main digital platforms both under Articles 5 to 7 of the DMA and under competition law rules will overlap and create a risk of incoherent enforcement, especially on the side of the European Commission. Against this background, the paper strives to draw out the narrow enforcement gap left for competition authorities. In addition, the paper highlights a number of alternatives open to competition authorities when enforcing competition law rules on digital markets, namely the segmentation of its enforcement efforts depending on the type of service concerned in each case.
