Thank you Brick Court and Stewarts, among other, for flagging  EWHC 1964 (Ch) Vattenfall et al v Prysmian et al in which the High Court dismissed a call for summary judgment on the grounds of lack of jurisdiction.
A classic case of follow-up damages litigation in competition law, here in the high voltage power cables cartel, fines for which were confirmed by the CJEU early July. Core to the case is the application of Article 8(1)’s anchor defendants mechanism. Only two of the defendants are UK incorporated companies – UK subsidiaries of companies that have been found by the European Commission to have infringed EU competition law.
Authority cited includes of course CDC, Roche Nederland and Painer, and Cooper Tyre (sale of the cartelised products can amount to implementation of the cartel). Vattenfall confirms that for the English courts, ‘knowingly implementing’ the cartel has a low threshold.
At 89 ff the Court refers to the pending case of (what I now know to be) C-724/17 Skanska Industrial Solutions e.a.: Finnish Courts are considering the application for cartel damages against parent companies on acquiring cartelist subsidiaries, had dissolved them. Relevance for Vattenfall lies with the issue of knowledge: the Finnish courts wonder what Article 101 TFEU has to say on the degree of knowledge of the cartelist activities, relevant for the liability of the parent company. An application of fraus, or abuse in other words. Elleray DJ however, did not consider the outcome of that reference to be relevant for the case at hand, in its current stage of procedure.
