Abstract: Personal data are both protected by a fundamental right and serves as a source of market power. As such, a complex interplay between data protection and competition law arises, sparking debate among policymakers and scholars on whether to incorporate data protection considerations (DPCs) in competition law assessments. Proponents argue that competition cases involving such an interplay require a normative contribution from data protection law, while opponents emphasize the practical challenges of considering data protection as a non-economic public policy objective. We identify nine ways in which data protection might ultimately surface in competition law assessments, categorized into five areas: (i) competition enforcement actions, (ii) existing legal and regulatory framework, (iii) personal data collection, (iv) exclusionary abuses, and (v) alleviation of competition concerns. Using a multiple-step approach for qualitative document analysis, we explore how these considerations have surfaced in the European Commission’s decisional practice through a dataset of 2.041 EU competition decision texts based on articles 101 TFEU and 102 TFEU and the EU Merger Regulation. We identify 53 decisions where DPCs have surfaced, especially in the information and communication industry, where they are more frequently subjected to commitments. In line with the evolving literature, we observe an increasingly integrationist trend as these considerations surface more frequently, particularly since the adoption of the General Data Protection Regulation in 2016 and the Digital Markets Act proposal in 2020. We also find a pattern where data protection provisions are included in commitments as a ‘tick-the-box’ exercise. Several influential alleviations of competition concerns suggest that the Commission is more comfortable using data protection to approve transactions unconditionally rather than as a substantive argument for commitments. We conclude by making a case for a more collaborative approach based on the European Court of Justice’s recent Meta Platforms (2023) judgment. Data protection should be considered in competition law assessments if its normative contribution is required. Such a stance would simply align with the internal logic of competition law without unlawfully expanding its material scope.
