Conflict of laws – Anti-suit injunction. The claimant companies were granted an anti-suit injunction to restrain the defendant bank from continuing Russian proceedings against them and from commencing proceedings in any court of a state which was not a member of the EU. However, the Commercial Court dismissed the claimants' application for anti-suit injunction to restrain the bank's pursuit of proceedings in Cyprus, because it was an EU member state and the decision of the Court of Justice of the European Union in West Tankers Inc v Alllianz SpA[2009] 1 All ER (Comm) 435 (which the court held to be valid) prevented the grant of an anti-suit injunction to restrain the pursuit of those proceedings.
