A plaintiff must show that there is a ‘serious issue for trial’ to support and justify an application for overseas service. The standard of proof in respect of the cause of action relied on is whether, on the evidence, there was a serious question to be tried, i.e. a substantial question of fact or law, or both, which the claimant bona fide desired to have tried.
Lord Goff said: ‘it is difficult to see why the fact that the writ is to be served out of the jurisdiction should have any particular impact upon the standard of proof required in respect of the existence of the cause of action. On this point, I find myself in respectful disagreement with the opinion expressed by Lloyd LJ to the contrary in the Court of Appeal  1 Lloyd’s Rep. 236, 242. I prefer the approach of Stuart-Smith LJ when . . he commended his preferred view as consonant with common sense and policy, and continued:
‘It seems to me to be wholly inappropriate once the question[s] of jurisdiction and forum [conveniens] are established for there to be prolonged debate and consideration of the merits of the plaintiffs’ claim at the interlocutory stage.’
It has been suggested that, since both the assessment of the merits of the plaintiff’s claim and the principle of forum conveniens fall to be considered as elements in the exercise of the court’s discretion, these should be regarded as interrelated in the sense that ‘the more conspicuous the presence of one element the less insistent the demands of justice that the other should also be conspicuous:’ see Societe Commerciale de Reassurance v. Eras International Ltd.(formerly Eras (U.K.)  1 Lloyd’s Rep. 570, 588, per Mustill L.J. This approach originated in the speech of Lord Oaksey in Korner’s case, at pp. 881-882, to the effect that the strength of the evidence in that case as to forum conveniens was such that only the slightest evidence was required of there having been a breach of contract within the jurisdiction. Lord Oaksey’s speech also provided the inspiration for an expression of opinion by Parker L.J. to the effect that, if there is overwhelming evidence that England is the appropriate forum, it will be enough that, on the merits, the plaintiff’s case is worthy of serious consideration: see Overseas Union Insurance Ltd. v. Incorporated General Insurance Ltd.  1 Lloyd’s Rep. 439, 448, and see also.  2 Lloyd’s Rep. 19, Banque Paribas v. Cargill International S.A 25. I must however express my respectful disagreement with this approach. Suppose that, for example, the plaintiff’s case is very strong on the merits. If so, I cannot see that a case particularly strong on the merits can compensate for a weak case on forum conveniens. Likewise, in my opinion, a very strong connection with the English forum cannot justify a weak case on the merits, if a stronger case on the merits would otherwise be required. In truth, as I see it, the two elements are separate and distinct. The invocation of the principle of forum conveniens springs from the often expressed anxiety that great care should be taken in bringing before the English court a foreigner who owes no allegiance here. But if jurisdiction is established under rule 1(1), and it is also established that England is the forum conveniens, I can see no good reason why any particular degree of cogency should be required in relation to the merits of the plaintiff’s case.
Once it is recognised that, so far as the merits of the plaintiff’s claim are concerned, no more is required than that the evidence should disclose that there is a serious issue to be tried, it is difficult to see how this matter, although it falls within the ambit of the court’s discretion, has not in practice to be established in any event. This is because it is very difficult to conceive how a judge could, in the proper exercise of his discretion, give leave where there was no serious issue to be tried. Accordingly, a judge faced with a question of leave to serve proceedings out of the jurisdiction under Order 11 will in practice have to consider both (1) whether jurisdiction has been sufficiently established, on the criterion of the good arguable case laid down in Korner’s case, under one of the paragraphs of rule 1(1), and (2) whether there is a serious issue to be tried, so as to enable him to exercise his discretion to grant leave, before he goes on to consider the exercise of that discretion, with particular reference to the issue of forum conveniens.’
