“The English court had a long-standing and well-established jurisdiction to grant an injunction restraining the commencement or continuation of foreign proceedings brought in breach of an arbitration clause, even when neither party had commenced, nor intended to commence, arbitration proceedings in the agreed forum. The Arbitration Act 1996 did not affect the court’s power under that jurisdiction or under s 37 of the Senior Courts Act 1981.”
