“The general undesirability of such concurrent proceedings is … but one consideration to be weighed as part of the overall assessment. It cannot necessarily lead to a stay or setting aside of English proceedings. It may, on the facts, be correct to restrain the pursuit of the foreign proceedings…or to make no order.””
“To justify the grant of an injunction, the defendant must show: (a) that the English court is the natural forum for the trial of the action, to whose jurisdiction the parties are amenable; and (b) that justice does not require that the action should nevertheless be allowed to proceed in the foreign court.”
“In practice, however, the principle so stated would have the effect that, where parties are in dispute on the point whether the action should proceed in an English or foreign court, the English court would be prepared, not merely to decline to adjudicate by granting a stay of proceedings on the ground that the English court was forum non conveniens, but, if it concluded that England was the natural forum, to restrain a party from proceeding in the foreign court on that ground alone. Their Lordships cannot think that is right.”
“…..the English ….. court will, generally speaking, only restrain the plaintiff from pursuing proceedings in the foreign court if such pursuit would be vexatious or oppressive. This presupposes that, as a general rule, the English ….. court must conclude that it provides the natural forum for the trial of the action; and further, since the court is concerned with the ends of justice, that account must be taken not only of injustice to the defendant if the plaintiff is allowed to pursue the foreign proceedings, but also of injustice to the plaintiff if he is not allowed to do so. So the court will not grant an injunction if, by doing so, it will deprive the plaintiff of advantages in the foreign forum of which it would be unjust to deprive him.”
“I agree that it would be most unwise, unless one was actually driven to do so for the purpose of deciding this case, to lay down any definition of what is vexatious or oppressive, or to draw a circle, so to speak, round this court unnecessarily, and to say that it will not move outside it. I would much rather rest on the general principle that the court can and will interfere whenever there is vexation and oppression to prevent the administration of justice being perverted for an unjust end. I would rather do that than attempt to define what vexation and oppression mean; they must vary with the circumstances of each case.”
“All of this is uncontroversial; but it has to be recognised that it does not provide very much guidance to judges at first instance who have to decide whether or not to exercise the jurisdiction in any particular case”
“….. I respectfully agree with the approach of Hobhouse J and just add a word or two of my own. First, to agree non-exclusive jurisdiction in my view means as Hobhouse J held in that case, and, as I followed him in holding in British Aerospace v Dee Howard & Co. [1993] 1 LL 368, that the parties agreed to submit to that jurisdiction and cannot object to that court accepting jurisdiction, and that the parties are implicitly agreeing that jurisdiction as appropriate. They are not so agreeing in relation to any other jurisdiction by the term non-exclusive. All the term non-exclusive means is that there is no contractual bargain not to start proceedings elsewhere; any other relevant point for contesting jurisdiction (other than in the place expressly chosen non-exclusively) will be open to the parties. Second, in addition to there being no question of the English court arrogating to itself a decision as to the natural forum when there is a non-exclusive jurisdiction clause, it seems to me much less likely that a foreign court will be offended if the court to whose jurisdiction the parties have agreed to submit, grants an injunction, particularly where that court’s resources are being used and where proceedings in the foreign court might affect English proceedings, e.g. by the risk of witnesses having to be in two places or by the English process being lengthened by the examination of witnesses who have already given depositions under a foreign procedure. Third, I am doubtful whether a party can rely on a procedural advantage in some country other than the one to whose jurisdiction he has on any view submitted, as a juridical advantage. Putting this point another way, can it seriously have been contemplated that when these parties agreed a non-exclusive jurisdiction clause in favour of England that they were agreeing that if the English courts and its procedures were adopted for the purpose of any action, that, in addition, the same issues could be litigated elsewhere if there was some procedural advantage in the sense of discovery to be gained by so doing. Thus, when I come to examine the facts to which I will now turn, I am unpersuaded that the Defendants, the Enron parties, are entitled to start from the point of view that they had an agreement under which they were entitled to litigate in Texas contemporaneously with any proceedings which were at that stage being litigated in the United Kingdom.”
