Forum shopping in cartel cases: the CJEU does not cast its anchor lightly
03 June 2026
On 16 April 2026, the Court of Justice of the European Union (“CJEU”) delivered an important judgment on the question of when victims in cartel damage cases may sue multiple group companies before a single court. The judgment is relevant for companies operating within international group structures, but also for parties seeking to recover damages following a competition infringement. Central to the case is the so-called ‘anchor defendant’: a defendant established in the Netherlands who is used to bring foreign co-defendants before the Dutch courts.
The background
The ruling stems from two Dutch proceedings before the Amsterdam Court of Appeal. The first case concerned claims for damages arising from the power cables cartel. The second case concerned claims for damages arising from an Italian cartel in the market for cardboard and packaging materials.
In both proceedings, not only were companies summoned that were directly named in a cartel decision, but also other group companies. Some of these were established in the Netherlands and acted as anchor defendants. The claimants sought to bring all defendants jointly before the Dutch courts on the basis of Article 8(1) of the Brussels I bis Regulation.
That provision allows multiple defendants to be summoned before the court of the domicile of one of them, provided there is such a close connection between the claims that joint proceedings are desirable. The aim of this is to prevent different courts from issuing conflicting decisions.
The judgment of the CJEU
The CJEU has ruled that a close connection may also exist where the anchor defendant is not itself designated as a liable party in the cartel decision. The decisive factor is whether there are serious indications that the anchor defendant belongs to the same ‘undertaking’ within the meaning of competition law as the entities to which the infringement has been attributed.
The concept of ‘undertaking’ in EU competition law is broader than that of a separate legal entity. Different companies within a group may together form a single economic unit. In such a case, liability for a cartel infringement may, under certain circumstances, extend throughout the group.
The CJEU does emphasize, however, that Article 8(1) must not be used artificially. A claimant may therefore not sue a Dutch company with no genuine connection to the dispute solely to bring foreign parties to the Netherlands. However, when determining jurisdiction, the court does not need to assess in full whether the claim against the anchor defendant will succeed on its merits. This may only be relevant if that claim is manifestly unfounded or artificial.
Finally, the CJEU confirms that Article 8(1) not only designates international jurisdiction but also the court with relative jurisdiction within the Member State: the court of the domicile of the defendant against whom the action is brought. A national referral to another competent court within the same Member State remains possible, provided that this does not undermine the effectiveness of the Regulation.
Implications for practice
This judgment strengthens the position of claimants in cartel damages cases. They are given greater scope to concentrate related claims against various group companies before a single court, even if the anchor defendant is not itself named in the cartel decision.
For international groups, this means that group structures must be scrutinized. Even companies that are not themselves the addressees of a fine decision may be involved in civil proceedings if they form part of the same economic unit. The judgment thus once again underlines the importance of effective competition law compliance across the entire group.
