Clifford Chance v Soc Gen: The makings of a jurisdictional stalemate between the English and French courts.

In Clifford Chance LLP v Societe Generale SA [2023] EWHC 2682 (Comm), Henshaw J has held on a jurisdiction challenge in a claim for professional negligence claim brought by SocGen against Clifford Chance alleging that they negligently handled a dispute between SocGen and Goldas Kuyumculuk Sanayi Ithalat Ihracat AS and other companies in the same group.

Clifford Chance’s claim is one for negative declaration of contractual liability: it seeks declarations that they are not liable to SocGen in professional negligence, and that CC Europe was not retained by SocGen at all. SocGen has subsequently commenced proceedings against CC LLP and CC Europe in the High Court of Paris, seeking damages in excess of €140 million. The first hearing in that court is due to take place in March 2024.

SocGen challenged the jurisdiction of the E&W courts with reference to its framework agreement with Clifford Chance, which includes French choice of court and French choice of law. As was to be expected, Clifford Chance argue that that agreement does not apply to the work at issue (given the interference of various Clifford Chance legal entities, it was inevitable that issues of privity would arise; see also the discussion [103] ff on agency). The judge, applying French principes of contractual interpretation, holds [90] ff that on the facts, the framework agreement does not apply to the retainer at issue. As a result of the Rome Convention (as discussed at [67], Rome I not applying ratione temporis), English law applies to that retainer as a result of E&W being the habitual residence of the service provider.

[112] ff deal succinctly with (and reject)  the subsidiary issue of forum non conveniens: [120] it is not shown

that the courts of France are clearly and distinctly the more appropriate forum. To the contrary, this court is that forum.

I wonder whether Clifford Chance in the French proceedings will now be arguing Article 33-34 lis pendens, seeing as the English proceedings were instituted first, however that would depend on the exact parties to the proceedings and the basis for jurisdiction against them: if the French courts find there is a legally binding choice of court in the claim, Articles 33-34 cannot apply and we will find ourselves in an interesting post-Brexit competition between courts.
