“The test which has been developed for distinguishing an exclusive from a non-exclusive jurisdiction clause is whether on its proper construction the clause obliges the parties to resort to the relevant jurisdiction, irrespective of whether the word “exclusive” is used: Dicey and Morris 13th. ed 2000 at para.12-078. Or to put the issue in another way: is the obligation contained in the clause the intransitive one to submit to a jurisdiction if it is chosen by the other contracting party, or is it the transitive one to submit all disputes to the chosen jurisdiction ?”
“(i) The Court will grant an injunction where the pursuit of the foreign proceedings is "unconscionable", as is made clear by the House of Lords in Turner v Grovit[2002] 1 WLR107 at paragraphs 22-29, per Lord Hobhouse. The injunction is a personal remedy for the wrongful conduct of another party - a fault based remedial concept, in respect of conduct which the Court may describe as "vexatious" or "oppressive", but deriving from "the basic principle of justice". (ii) The Court will readily grant an injunction to restrain proceedings which are brought in breach of an exclusive jurisdiction clause save in circumstances where the Brussels Regulation applies – see Through Transport Mutual v New India Assurance Co. [2005] 1LLR 67 at paragraph 67 – 68. This is an example of the wider principle that an English Court will grant an injunction to prevent the pursuit of foreign proceedings which are vexatious, oppressive or unconscionable – see SNIA v Lee Kui Jack[1987] AC 871 . iii) Absent an agreement to the exclusive jurisdiction of the English Court, or some other special factor, a person has no right not to be sued in a particular forum. Where suit is brought in a foreign forum, the question whether or not that forum is an appropriate forum is a factor in assessing the conduct of the party suing there, for the purposes of considering whether to grant a restraining injunction, but if it is the only factor, it is easily overridden by other considerations (per Lord Hobhouse at para 25 of Turner (ibid)). iv) To grant an injunction, the English Court must have a sufficient legitimate interest in the foreign proceedings, which means that if there is no contractual reason to prevent suit there, there must be proceedings in this country which require protection (per Lord Hobhouse at para 27 of Turner (ibid), by reference to the House of Lords' decision in Airbus Industries GIE v Patel[1999] 1 AC 119 . v) English law attaches a high importance to international comity and the perception of the foreign court of an interference in its proceedings, albeit indirect. There must therefore be a clear need for protection of the English proceedings (per Lord Hobhouse at para 29 of Turner (ibid) if an injunction is to be granted. vi) An injunction should not be granted if its effect would be to deprive the claimant in the foreign action of an advantage in that forum of which it would be unjust to deprive him (Snia v Lee Kui Jak (ibid) at p 896).”
