On 6 November 2022, the Portuguese Competition, Regulation and Supervision Court of Santarém rendered a key judgment in relation to damages proceedings against participants in the European Trucks Cartel. The Court addressed key points, such as the standard of proof, limitation periods, and net price effects in a comprehensive EU case law state of play-based interpretation of national law. Granting the 15.4% overcharge identified in the claimant’s expert report and rejecting the defendant’s “no damage” argumentation, this judgment will have a positive impact beyond the Trucks Cartel case.
