“if any businessman did want to exclude disputes about the validity of a contract, it would be comparatively easy to say so.”
“the clear and simple ground that the defendant has promised not to bring [the foreign proceedings]”
“6 There is no difference in principle between an injunction to restrain proceedings in breach of an arbitration clause and one to restrain proceedings in breach of an exclusive jurisdiction clause. The justification for the grant of the injunction in both cases is that without it the claimant will be deprived of its contractual rights in a situation in which damages are manifestly an inadequate remedy (see The Angelic Grace,[1995] 1 Lloyds Rep 87 at 96, Millett LJ.) 7 It would be inappropriate to grant an interlocutory injunction to restrain foreign proceedings at a time when it is no more than arguable that they were brought in breach of contract, because it could not be said that such proceedings were vexatious or oppressive (see Clarke LJ in National Westminster Bank v Utrecht-America Finance Company [2001] 3 All ER (Comm) 7). 8 On an application to restrain foreign proceedings brought in (alleged) breach of an arbitration agreement alleged to be governed by English law, the applicant must show to a high degree of probability that its case is right and that it is entitled as of right to restrain the foreign proceedings (see Colman J in Bankers Trust Co v PT Mayora Indah (20 January 1999 , unreported ) and Cresswell J in Bankers Trust Co v PT Jakarta International Hotels and Development [1999] All ER (Comm) 785 ).” 55 In Midgulf International Ltd v Groupe Chimique Tunisien[2009] 2 Lloyd's Rep 411 , Teare J said: “This is a case where an anti-suit injunction is sought at the interlocutory stage of proceedings. However, if the injunction is granted its effect is likely to be final because it will end the Tunisian proceedings and enable the arbitration proceedings to be completed. In such circumstances this court has required the applicant for an anti-suit injunction to establish ‘a high degree of probability' that its case against the respondent is right and that it is indeed entitled as of right to restrain the respondent from taking proceedings abroad.” 56 Teare J then held that Midgulf's “strongly arguable” case was not sufficient because it ultimately depended on evidence about the content of certain telephone conversations. He said: “The court is not therefore able to reach the conclusion that Midgulf has established ‘a high degree of probability' that its case against GCT, that the July contract included a London arbitration clause, is right and that it is therefore entitled as of right to restrain GCT from taking proceedings in Tunisia. I accept that Midgulf has a strongly arguable case to that effect but that is not sufficient in the present context for the reasons stated in Bankers Trust v Jakarta and American International Speciality Lines Insurance v Abbott Laboratories. That would suggest that the anti-suit injunction granted ex parte on notice by Burton J must be refused.” 57 Teare J held, however, that on the particular facts of that case there was doubt as to whether the Tunisian court would decide the question as to whether the relevant contract contained a London arbitration clause. The reason the Tunisian was not prepared to decide that question, in a judgment it had given on GTC's application for a declaration that there was no arbitration agreement between the parties, is not entirely clear but appears to have been either on the basis that the arbitral tribunal itself must decide the question or as a result of a provision of the Tunisian Constitution that the court not decide that question in a declaratory action. In those rather unusual circumstances, Teare J held that the appropriate course on case management grounds was to order a speedy trial of the issues as to the terms on which the July contract was agreed and to continue the anti-suit injunction until then. 58 In Youell v Kara Mara Shipping Co Ltd[2000] 2 Lloyd's Rep 102 , Aikens J (as he then was) adopted the good arguable case test, but the matter appears not to have been the subject of any specific argument. 59 I accept that Transfield has a good arguable case that there is a binding charter party agreement containing a London arbitration clause, but I am not persuaded that there is a high probability of it establishing that that is so. “6 There is no difference in principle between an injunction to restrain proceedings in breach of an arbitration clause and one to restrain proceedings in breach of an exclusive jurisdiction clause.
