On 10 November 2022, the EU Court of Justice rendered another key judgment in relation to the series of damages proceedings brought in Spain against participants in the European Trucks Cartel. This judgment on the interpretation of Art. 5(1) of the Damages Directive clarifies the wide scope of evidence to which claimants can request access to substantiate potential damages claims. The judgment further strengthens the effectiveness of private enforcement of EU competition rules and should have a positive impact on the whole wave of compensation claims against truck manufacturers in Europe.
