Another Victory for Arbitration: the UK Supreme Court


The United Kingdom’s highest court, the Supreme Court, has confirmed that English courts may intervene to issue an “anti-suit” injunction to restrain a party from bringing court proceedings in violation of an arbitration clause even if there are no arbitration proceedings in existence. This will be welcome news to the many insurers and reinsurers who incorporate London arbitration clauses into their policies, including carriers in the Bermuda market who frequently stipulate for coverage disputes to be resolved through arbitration in London under the English Arbitration Act 1996.   

The appeal arose out of a high value dispute involving the operation of a hydroelectric power plant in Kazakhstan and a concession agreement that provided for disputes to be arbitrated in London.  The owner of the plant issued court proceedings in Kazakhstan and obtained an order declaring the arbitration agreement invalid.  The operator then filed court proceedings in England seeking a declaration that the arbitration agreement was valid and enforceable and an anti-suit injunction to restrain the owner from continuing the Kazakhstan proceedings in violation of the arbitration clause. However, the operator chose not to file arbitration proceedings seeking any relief in relation to the concession agreement.

The English court granted both the declaratory and injunctive relief sought. The owner then appealed to the Supreme Court on the grounds that English courts have no jurisdiction to restrain foreign proceedings brought in violation of an arbitration clause where no arbitral proceedings have been commenced or are proposed.  In dismissing the appeal, the Supreme Court affirmed that the English courts have a long-standing and well-recognized jurisdiction to restrain foreign proceedings brought in violation of an arbitration clause even where no arbitration is on foot or in contemplation.

While the Supreme Court’s ruling is unlikely to come as a surprise to most arbitration practitioners, its unequivocal support of the arbitration process – even in light of a contrary ruling by a foreign court – will provide comfort to the many insurers and reinsurers who chose London as the venue for any arbitrations arising under their polices.
