“So I turn to the crucial question of what influence upon the exercise of his discretion whether to grant a stay of the English proceedings or not the judge should have attributed to the fact that at the time the stay was applied for there was already proceeding in a natural and appropriate forum, the District Court of Sariyer, litigation between the same parties about the same subject matter in which the roles of plaintiff and defendant were reversed. My Lords, the essential change in the attitude of the English courts to pending or prospective litigation in foreign jurisdictions that has been achieved step-by-step during the last 10 years as a result of the successive decisions of this House in The Atlantic Star [1974] A.C. 436; MacShannon [1978] A.C. 795 and Amin Rasheed [1984] A.C. 50, is that judicial chauvinism has been replaced by judicial comity to an extent which I think the time is now ripe to acknowledge frankly is, in the field of law with which this appeal is concerned, indistinguishable from the Scottish legal doctrine of forum non conveniens.”
"the plea can never be sustained unless the court is satisfied that there is some other tribunal, having competent jurisdiction, in which the case may be tried more suitably for the interests of all the parties and for the ends of justice."
“in order to justify a stay, two conditions had to be satisfied, one positive and the other negative: (a) the defendant had to satisfy the court that there was another forum to whose jurisdiction he was amenable in which justice could be done between the parties at substantially less inconvenience or expense, and (b) the stay was not to deprive the plaintiff of a legitimate personal or juridical advantage which would be available to him if he invoked the jurisdiction of the English court.” adding that “If the distinction between this re-statement of the English law and the Scottish doctrine of forum non conveniens might on examination prove to be a fine one, I cannot think that it is any the worse for that.”
“Thirdly, and this concept emerges most clearly from the speech of Lord Wilberforce in The Atlantic Star [1974] A.C. 436, the exercise of the court's discretion in any particular case necessarily involves the balancing of all the relevant factors on either side, those favouring the grant of a stay on the one hand, and those militating against it on the other. Such balancing may be a difficult process and some cases may be very near the line.”
“Where a suit about a particular subject matter between a plaintiff and a defendant is already pending in a foreign court which is a natural and appropriate forum for the resolution of the dispute between them, and the defendant in the foreign suit seeks to institute as plaintiff an action in England about the same matter to which the person who is plaintiff in the foreign suit is made defendant, then the additional inconvenience and expense which must result from allowing two sets of legal proceedings to be pursued concurrently in two different countries where the same facts will be in issue and the testimony of the same witnesses required, can only be justified if the would-be plaintiff can establish objectively by cogent evidence that there is some personal or juridical advantage that would be available to him only in the English action that is of such importance that it would cause injustice to him to deprive him of it.”
“In my judgment the criticism made by the Court of Appeal, that Sheen J. erred in principle in treating the co-existence of the Turkish action as a decisive factor on the facts of the present case, is not justified. It was not a case of mere balance of convenience; it was an overwhelming case. It was not a case of mere disadvantage of multiplicity of suits, it was a case which was liable to cause, if both actions continued, much difficulty and trouble. On the footing that the Court of Appeal were wrong in holding that the judge erred in principle in the way that they thought there was, in my opinion, no valid ground for their interfering with the exercise of the discretion vested in him as the judge of first instance.”
“There was ample material from which Sheen J. came to the conclusion that the Sariyer District Court of Turkey is a forum in which justice can be done between the parties at substantially less inconvenience and expense and that a stay of the English proceedings will not deprive the Cuban owners of a legitimate personal or jurisdictional advantage which will be available to the Cuban owners if they invoke the jurisdiction of the English court. In other cases, where these conditions are not satisfied, English proceedings will not be stayed merely because of the dangers and difficulties of concurrent actions. There is ample scope for a litigant to choose the exercise of English jurisdiction …… notwithstanding that proceedings have already been instituted under a foreign jurisdiction provided that the events which happen prior to the hearing of an application for a stay of the English proceedings do not demonstrate that the foreign forum is to be preferred on grounds of convenience and expense. An ugly rush to get one action decided ahead of the other is not to be replaced by an ugly rush to issue proceedings in one country before the issue of proceedings in another…….”
“This passage has been quoted on a number of occasions in later cases in your Lordships' House. Even so, I do not think that Lord Diplock himself would have regarded this passage as constituting an immutable statement of the law, but rather as a tentative statement at an early stage of a period of development…”
“In the course of his careful and illuminating judgment Hirst J. dealt fully with the principles laid down by the House of Lords in The Spiliada [1987] A.C.460 and also made reference to the more recent decision of the Court of Appeal in Du Pont v Agnew [1987] 2 Lloyds L.R. 585. For my part I find it impossible to say that the judge erred in principle or either took into account some irrelevant consideration or ignored a relevant one. He had well in mind the general undesirability of concurrent proceedings in two different jurisdictions but nevertheless reached the conclusion that the proceedings in England should not be stayed. ”
“But as I read that passage (ie the passage from Dicey referring to De Dampierre) any such dilution is confined to cases where foreign proceedings have not passed beyond the stage of being initiated and have been started merely for the sake of demonstrating that a competing jurisdiction exists. That is not the position here and while the existence of prior foreign proceedings is not, by itself, decisive, it deserves weight…”
“[Lord Goff] made no express reference to the difficulties inherent in parallel proceedings as a reason in themselves (absent anything else) to justify a stay, any more than Lord Diplock did in his speech in The Abidin Daver. The ratio of that case depends on the foreign court being a natural and appropriate forum for the resolution of the dispute. Indeed it is clear from the test formulated by Lord Goff in Spiliada that the jurisdiction of the English court can only be displaced if the foreign court is the more natural and appropriate forum. The commencement of an earlier action there does not by itself establish that. This point was confirmed by Lord Goff in the later case of [De Dampierre]at page 108, where he expressly considered the effect of existing proceedings in the foreign jurisdiction [Patten J went on to cite the passage which I have already set out above]”
