The UK Supreme Court has provided its reasoned decision in the case of UniCredit Bank v RusChemAlliance for upholding an anti-suit injunction restraining a Gazprom affiliate from pursuing litigation in Russia in breach of a Paris-seated ICC arbitration agreement. In a first of its kind, the Supreme Court concluded that the English courts did have jurisdiction to issue the injunctive relief, and that they were the proper place to do so, even though the place of arbitration was situated outside of the UK, in a jurisdiction (France) where no such remedy was available. Charles Claypoole from Latham & Watkins LLP led the team acting as counsel to UniCredit Bank, with Stephen Houseman KC and Stuart Cribb from Essex Court Chambers appearing before the Supreme Court. Jean-Christophe Honlet acted as French law expert witness for UniCredit Bank. https://globalarbitrationreview.com/article/uk-supreme-court-gives-reasons-gazprom-injunction
Update: in April 2025, the UK Supreme Court decision was voted by Global Arbitration Review (GAR) as the most important arbitration decision of 2024, globally. https://globalarbitrationreview.com/article/fellas-abu-dhabi-centre-and-latham-win-largest-ever-gar-awards
