Premier Cruises Ltd v DLA Piper Rus Ltd & Anor  EWHC 151 (Comm) is a textbook case for the relationship between arbitration and the Brussels Ia regulation, as well as relevance of lex arbitri on what is within the scope of an arbitration agreement.
Claimant is Premier Cruises Limited (“PCL”), a company originally domiciled in the British Virgin Islands and now domiciled in the Seychelles, which owns or operates two vessels. Defendants are entities within the DLA Piper Group of legal practices. The First Defendant is DLA Piper Rus Limited (“DLA Russia”), an English company with operations in Russia. The Second Defendant is DLA Piper UK LLP (“DLA UK”), an English LLP. On 29 January 2020 (within the scope of Brussels Ia, therefore, at least as against DLA UK), PCL commenced proceedings against DLA in the Commercial Court claiming damages in contract and/or in tort for professional negligence.
DLA Russia argues the claim is within the scope of its arbitration agreement included in the engagement letter (International Commercial Arbitration Court at the Chamber of Commerce and Industry of the Russian Federation). DLA UK accepted it was not included in that agreement and applied for a case-management stay.
PCL argue its action against DLA Russia is in respect of advice allegedly given and work allegedly carried out by DLA Russia prior to 26 May 2015 when the Engagement Letter came into force.
At 52, Edward J identified Russian law as both lex contractus and lex arbitri, and held at 138 after hearing the Russian law experts, that upon contractual construction, PCL’s claim was not included in the clause for it was not meant to apply retroactively.
At 147 ff he agreed with PCL that a case-management stay for the claim against DLA UK is not possible given, with reference to Recital 12 BIa, that the arbitration exception is not engaged: ‘The claim made against DLA UK in this action is not one in respect of which PCL and DLA UK have entered into an arbitration agreement ; Arbitration is not the principal focus of the English proceedings against DLA UK; the essential subject matter of the claim made against DLA UK does not concern arbitration; and the relief sought in the proceedings is not ancillary to or an integral part of any arbitration process  (reference is made to The Prestige].
The claim being within BIa, Owusu rules out a case management stay. The judge should have outright rejected the additional suggestion ([158 juncto ) of a temporary stay being within the Owusu confines.
