Abstract

This article examines the evolving normative order of the European Union in the field of competition law, focusing on the interplay between public enforcement by competition authorities and private damages claims before national courts. Building on the jurisprudence of the Court of Justice of the European Union (CJEU), the paper highlights the recognition of a right to compensation for any natural or legal person harmed by infringements of Articles 101 and 102 TFEU, irrespective of contractual relationships or prior administrative findings. Central to this discussion is the tension between ensuring effective access to evidence for claimants and safeguarding the attractiveness of leniency programmes, which remain vital tools for uncovering cartels. The analysis explores landmark cases such as Courage and Crehan, Manfredi, Pfleiderer, and Donau Chemie, which collectively shaped the principles of effectiveness, equivalence, and transparency in private enforcement. The article further assesses Directive 2014/104/EU, which seeks to harmonize disclosure rules across Member States while preventing overcompensation and preserving incentives for voluntary cooperation. Particular attention is given to the Commission’s restrictive stance on access to leniency-related documents under Regulation No 1049/2001 and the judicial pushback against blanket refusals of disclosure. By situating these developments within broader debates on collective redress, proportionality, and discretionary remedialism, the paper argues that the EU legal framework must strike a delicate balance: enabling victims to obtain full compensation without undermining public enforcement mechanisms. Ultimately, the study underscores the need for coherent, case‑by‑case judicial approaches that reconcile transparency, deterrence, and the integrity of competition law enforcement.
