EU Top Court to Cartel Members: Fight in Your Own Corner

THE BOTTOM LINE

  • Individual Legal Battles: Co-accused cartel members cannot automatically join each other’s legal challenges to a European Commission decision. Each company must build and argue its own case independently.
  • No Automatic Knock-On Effect: A legal victory for one party in a cartel case—for example, reducing the duration of their involvement—does not automatically benefit others. The Court views Commission decisions as a “bundle of individual decisions,” meaning your company’s liability is assessed separately.
  • Strategic Intervention is Limited: The right to intervene in another company’s case is highly restricted. The Court distinguishes between challenging the very existence of a cartel (where intervention might be possible) and arguing over specifics like the duration or fine calculation (where it is not).

THE DETAILS

This case stems from a 2024 European Commission decision that fined Czech Railways (ÄŒeské dráhy or ÄŒD) and Austrian Railways (ÖBB) for a collusive “gentleman’s agreement.” The Commission found they had worked together to restrict a competitor, RegioJet, from accessing used railway wagons, thereby hindering competition on the Prague-Vienna route. Both ÄŒD and ÖBB filed separate actions with the EU’s General Court to have the decision annulled. ÖBB’s case specifically argued that the Commission got the start date of the infringement wrong and that its involvement began several months later than alleged—a change that would reduce its fine. ÄŒD sought to formally join ÖBB’s case as an “intervener” to support this specific argument.

The Court of Justice has now issued a final “no” to this request, upholding the General Court’s earlier refusal. The core of the decision rests on the strict legal test for intervention: a party must prove a “direct and existing interest” in the final outcome of the case. The Court found ÄŒD’s interest to be merely indirect. It reasoned that even if ÖBB succeeds in its argument and gets its infringement period shortened, that ruling would only apply to ÖBB. The legal status of the decision against ÄŒD would remain unchanged, as the Commission’s decision is treated as a “bundle of individual decisions,” one for each addressee.

This ruling reinforces a crucial principle in EU competition litigation: corporate liability is individual. The Court clarified that ÄŒD is not being denied its right to be heard; it has its own, separate court case in which it can make the exact same arguments about the infringement’s start date. Allowing intervention on such grounds would create procedural complexity and blur the lines of individual accountability. The judgment effectively tells companies that while they may have been accused of acting together in the market, they must stand alone when they get to court.
