In Trayport Ltd v E-Star Trading GmbH [2026] EWHC 164 (Ch) ('Trayport'), HHJ Davis-White KC (sitting as a Judge of the Chancery Division)(the 'Judge') gave a long and detailed exposition of the law relating to orders for service of proceedings out of the Jurisdiction. This exposition:

(1) came after being '...referred to over 85 cases in the main and supplementary authorities bundles and a number of extracts from textbooks, statutes and other materials.' (paragraph 17) (though some related to the duty to make full and frank disclosure on a without notice application);

(2) spans 8 pages / 30 paragraphs;

(3) arose in proceedings, wherein the Court had before it, 2 applications by ((1) E-Star/Exxeta; and (2) Mr Schmid, respectively), to set aside an order giving permission to serve a Claim Form and Particulars of Claim on all the defendants (paragraphs 1 to 3). 

Exposition - Overview

Under the heading 'The Law regarding orders for service of proceedings out of the Jurisdiction', the Judge in Trayport:

(1) identified the key case - namely, AK Investment v Kyrgyz Mobil Tel Limited [2011] UKPC 7; [2012] 1 WLR 1804 (PC) ('Kyrgyz Mobile Tel'), wherein Lord Collins, at paragraph 71, identifies 3 requirements for permission;

(2) note that these 3 requirements are now encompassed within CPR r6.36 and PD6B paragraph 3 and CPR r6.37(1) and (3);

(3) considered, in detail, the 3 requirements, under the headings:

(a) 'Serious issue to be tried'.

(b) 'the appropriate forum';

(There is some discussion of the facts, within these paragraphs, particularly at paragraphs 52 to 55)

Separately, the Judge in Trayport also considered the law in respect to an applicant's obligation of full and frank disclosure, when making a without notice application (paragraphs 65 to 70)(here, to obtain permission to serve out of the jurisdiction).

It is noteworthy that, the Claimant's main allegation in its claim was for:

(a) infringement of the intellectual property rights of Trayport; and/or

(b) misuse of Trayport's confidential information (see paragraph 53).

In short, Trayport has a software platform called 'Joule'. Trayport inferred it had been wronged by the defendants, as: (a) it took a '...very short time to create an Exxeta/E-Star product akin to Joule compared with the time that it took to develop Joule' (paragraph 54) and (b) 4 employees left Trayport, and were believed to have taken up substantially similar roles at Exxeta/E-Star (paragraph 55) (around the time a Mr Schmid (Chief Technology Officer at Trayport) had also left Trayport). Further details of the Claimant's asserted causes of action, are provided in a footnote[1].

Summary

Along with the exposition of the law, helpfully, the Judge in Trayport also provided a summary. At paragraph 7, the Judge in Trayport said:

'To obtain an order for service of proceedings outside the jurisdiction on a defendant, a claimant will have to:

(1) establish that each claim raises a serious issue to be tried, that is, that it is a claim with a real (as opposed to fanciful) prospect of success;

(2) establish to the relevant standard, which is that there is "a good arguable case", that each claim falls within one of the jurisdictional gateways set out in paragraph 3.1 of CPR PD 6B;

(3) establish to the relevant standard that England is the appropriate forum;

(4) make full and frank disclosure,(see CPR r6.37(3)). The requirement set out in (4) above arises from the nature of the application for service out as being one that is made without notice to the Defendant.'

Exposition - Service of Proceedings out of the Jurisdiction

The Judge in Trayport said, at paragraphs 35 to 64:

'35. The relevant law was largely agreed, subject to the question of emphases.

36. The general position regarding the obtaining of an order for service of English legal proceedings on a defendant out of the jurisdiction is summarised by Lord Collins, giving the judgment of the board, in AK Investment v Kyrgyz Mobil Tel Limited [2011] UKPC 7; [2012] 1 WLR 1804 (PC) at paragraph 71. The case was actually an Isle of Man case, heard in the Privy Council, but Lord Collins referred to the position under English law and the jurisdictional requirements, as set out in his paragraph 71, are essentially the same under both legal systems:

"[71] On an application for permission to serve a foreign defendant …. out of the jurisdiction, the claimant… has to satisfy three requirements: Seaconsar Far East Ltd v Bank Markazi Jomhouri Islami Iran Ltd [1994] 1 AC 438, 453—457. First, the claimant must satisfy the court that in relation to the foreign defendant there is a serious issue to be tried on the merits, i.e. a substantial question of fact or law, or both. The current practice in England is that this is the same test as for summary judgment, namely whether there is a real (as opposed to a fanciful) prospect of success: eg Carvill America Inc v Camperdown UK Ltd [2005] 2 Lloyds Rep 457, para 24. Second, the claimant must satisfy the court that there is a good arguable case that the claim falls within one or more classes of case in which permission to serve out may be given. In this context "good arguable case" connotes that one side has a much better argument than the other: see Canada Trust Co v Stolzenberg (No 2) [1998] 1 WLR 547, 555—557, per Waller LJ affirmed [2002] 1 AC 1; Bols Distilleries BV v Superior Yacht Services (trading as Bols Royal Distilleries) [2007] 1 WLR 12, paras 26—28. Third, the claimant must satisfy the court that in all the circumstances [in this case England] is clearly or distinctly the appropriate forum for the trial of the dispute, and that in all the circumstances the court ought to exercise its discretion to permit service of the proceedings out of the jurisdiction."

37. These requirements are now encompassed within CPR r6.36 and PD6B paragraph 3 and CPR r6.37(1) and (3).

38. CPR r 6.36 provides:

"6.36 In any proceedings to which rule 6.32 or 6.33 does not apply, the claimant may serve a claim form out of the jurisdiction with the permission of the court, if any of the grounds set out in paragraph 3.1 of Practice Direction 6B apply."

It was initially common ground that neither r6.32 nor r6.33 (each dealing with cases where permission of the court is not required) apply in this case. As I shall explain that position has altered in one respect since Harris 1st. In particular, r6.33(2B) allows service out of the jurisdiction without the need to obtain court permission in the case of claims in respect of contracts containing a term conferring jurisdiction on the courts in England and Wales and that provision is now also relied upon.

39. CPR r6.37(1) and (3) provide as follows (so far as material):

"6.37

(1) An application for permission under rule 6.36 must set out-

(a) which ground in paragraph 3.1 of Practice Direction 6B is relied on;

(b) that the claimant believes that the claim has a reasonable prospect of success;

(c) the defendant's address or, if not known, in what place the defendant is, or is likely to be found.

(2) …….

(3) The court will not give permission unless satisfied that England and Wales is the proper place to bring the claim."

40. PD 6B paragraph 3.1 sets out a wide range of grounds or jurisdictional gateways: 25 in all. Each is complete in itself and independent of the others. All are concerned to identify some "substantial and not merely casual or adventitious link between the cause of action and England" (Brownlie v Four Seasons Holdings Inc [2017] UKSC 80; [2018] 1 WLR 192 at [28] per Lord Sumption (see also White Book note 6.37.13)).

41. In this case, at the commencement of the hearing before me, the Defendants represented before me expressly accepted certain jurisdictional gateways were available and did not challenge the permission to serve out given in respect of certain causes of action on the basis that there was no available jurisdictional gateway. I do not express any view about the applicability or otherwise of gateways so far as no gateway issue was raised. However, the same Defendants did submit that the following gateways at PD6B paragraph 3.1 replied upon by the Claimant were not available and that I should set aside permission to bring the related claims on that ground (whether or not I set it aside on other grounds, such as a failure to meet the merits test). The gateways in question were paragraph 3.1(6)(a) and (c) and 3.1(8A)(a). The relevant provisions are as follows:

"Service out of the jurisdiction where permission is required

3.1 The claimant may serve a claim form out of the jurisdiction with the permission of the court under rule 6.36 where—

Claims in relation to contracts

(6) A claim is made in respect of a contract where the contract—

(a) was (i) made within the jurisdiction or (ii) concluded by the acceptance of an offer, which offer was received within the jurisdiction;

(b) …

(c) is governed by the law of England and Wales;

(8A) A claim for unlawfully causing or assisting in:

(a) A breach of contract where the contact falls within one of paragraphs (6)(a) to (6)(c) above or within Rule 6.33(2B); or

A breach of contract falling within paragraph (7) above."

42. The duty of full and fair or frank disclosure arises from the fact that the application is (and was in this case) initially made and dealt with on a without notice basis.

43. I turn to consider each of the three requirements set out in the Kyrgyz Mobile Tel case in more detail.

(a) Serious issue to be tried

44. As regards a "serious issue to be tried", the test is, as I have said, the same as the summary judgment test, that is (in context) whether the claim has a "real prospect of success". This has been referred to as the "merits test".

45. The burden of showing that the individual cause of action has a "real prospect of success" lies on the claimant seeking permission to serve out of the jurisdiction. In VTB Capital plc v Nutritek International Corp.[2013] UKSC 5; [2013] 2 AC 337 (SC) Lord Neuberger said, at paragraph [90]:

"The mere fact that the defendant is challenging jurisdiction does not somehow impose a duty on him to specify his case. The onus is on the claimant to satisfy the court that there is a serious issue to be tried on the merits of the claim, and not on the defendant to satisfy the court that he has a real prospect of successfully defending it."

46. The authorities can be summarised as requiring the following:-

(1) A statement of case that is coherent and properly particularised and which sets out a claim that, on the assumption that the pleaded facts are supported by evidence, has a real prospect of success.

(2) Evidence supporting the pleaded allegations such that they have a real prospect of success.

(3) If (2) is met but there are defects in the pleading such that (1) is not met, then there may be a question as to whether amendment of the statement of case should be permitted.

(4) (1) and (3) must be met as regards (a) each claim brought and (b) each defendant against whom a claim is sought to be brought.

47. A claim does not raise a serious issue to be tried, that is a claim with a real prospect of success, in a number of identified circumstances:

"A claim does not have such a prospect where (a) it is possible to say with confidence that the factual basis for the claim is fanciful because it is entirely without substance; (b) the claimant does not have material to support at least a prima facie case that the allegations are correct; and/or (c) the claim has pleaded insufficient facts in support of their case to entitle the Court to draw the necessary inferences: Three Rivers District Council v Bank of England (No3) [2003] 2 AC 1."

(Elite Property Holdings Ltd v Barclays Bank plc [2019] EWCA Civ 204 at [41]).

48. A slightly different formulation has been set out in Kawasaki Kisen Kaisha v James Kemball [2021] EWCA Civ 33 by Popplewell LJ ("Kawasaki"). That was conveniently summarised by Thompsell J in Playtech Software Ltd v Games Global Ltd [2024] EWHC 3264 (Ch) ("Playtech") at [16]-[17]:

"[16] The approach to the first requirement, the merits test, was summarised by Popplewell LJ in Kawasaki at [18] (which I reproduce below but without the case references supplied by the Judge):

"i) It is not enough that the claim is merely arguable; it must carry some degree of conviction.

ii) The pleading must be coherent and properly particularised.

iii) The pleading must be supported by evidence which establishes a factual basis which meets the merits test: it is not sufficient simply to plead allegations which if true would establish a claim; there must be evidential material which establishes a sufficiently arguable case that the allegations are correct."

[17] I will call these principles the "Kawasaki Test". The test applies where there is an application to amend a statement of case (see Kawasaki at [17]) as well as where there is an application to serve out."

49. (As I have mentioned, the decision of Thompsell J was the subject of a successful appeal but that turned on whether the Judge had correctly identified on the facts that a particular gateway was satisfied (turning on whether he had correctly identified the applicable law to the claim) and does not invalidate his statement of the relevant principles. The Court of Appeal in that case also addressed the question of appropriate forum).

50. Although therefore the evidence itself may be insufficient to raise a case with a real prospect of success, the starting point, and indeed the focus, should be on whether the particulars of the claim have been adequately pleaded. In Okpabi v Royal Dutch Shell [2021] UKSC 3; [2021] 1 WLR 1294, Lord Hamblen stressed the importance of judicial restraint so as to avoid mini-trials and also the need to focus on the statements of case:

"[21] At para 9 of Vedanta Lord Briggs JSC emphasised that where, as in this case, the jurisdictional issue is whether there is a triable issue as against a defendant, it is important to observe judicial restraint and to avoid minitrials, in accordance with the well-known guidance set out by Lord Hope of Craighead in Three Rivers District Council v Governor and Company of the Bank of England (No 3) [2003] 2 AC 1 ….

[21] Where, as will often be the case where permission for service out of the jurisdiction is sought, there are particulars of claim, the analytical focus should be on the particulars of claim and whether, on the basis that the facts there alleged are true, the cause of action asserted has a real prospect of success. Any particulars of claim or witness statement setting out details of the claim will be supported by a statement of truth. Save in cases where allegations of fact are demonstrably untrue or unsupportable, it is generally not appropriate for a defendant to dispute the facts alleged through evidence of its own. Doing so may well just show that there is a triable issue."

51. I should add that the warnings that I have just cited are warnings to defendants of the risks of seeking to challenge the case put forward by a claimant if such challenge in effect calls for a mini-trial. However, it is important to note that the claimant too should not assume that it can depart from its pleaded case and rely solely on evidence to put forward its case without amending its statement of case. In that respect, Lord Hamblen in the Okpabi case said as follows: at paragraphs [103] to [105]:

"The mini-trial

[103] This was a jurisdiction challenge and concerned whether it was appropriate to grant permission to serve proceedings out of the jurisdiction on a foreign defendant. Those proceedings were meant to be as defined in the particulars of claim for which permission to serve out was sought. In this case the challenge was made on the grounds that the claimants had no arguable case against the anchor defendant. Where, as in this case, there are particulars of claim, that is an issue which should ordinarily fall to be addressed by reference to the pleaded case.

[104] If the issues are addressed by reference to the pleaded case, then the focus of the inquiry is clearly circumscribed and problems of lack of proportionality should generally be avoided.

[105] In the present case, not only did the parties choose to swamp the court with evidence, but it appears that the claimants chose not to update their pleadings to reflect the evidence. We were told that this is because they wanted to avoid producing various iterations of the pleading, but if they wanted to advance a case which was not reflected by their existing pleading then they should have amended it. In that way the proper focus of the inquiry can be maintained. Whilst one can understand that this may not have been possible in relation to documents produced during the appeal hearing, the claimants' laissez-faire attitude to the pleadings set in long before that."

52. In this case, the relevant Defendants represented before me make the point that the Claimant's evidence as it has emerged in relation to the applications before me displays a failure to amend the pleadings (or seek permission to do so) in circumstances where it relies on unpleaded matters by way of witness statement. I shall have to return to this point later in this judgment. I would also make the point though that the necessary starting point of a focus on the pleadings confirms that the manner in which this application was commenced, with no pleadings nor reference to their details, was unsatisfactory.

53. The next point to note is that, as pleaded, the Claimant's case is largely built upon inference, and in some parts, inference on inference. The main allegation, which is of infringement of the intellectual property rights of Trayport and/or misuse of Trayport's confidential information, relies upon inference from matters set out in paragraph 90 of the PoC. That paragraph pleads a "belief" of Trayport in such infringements/misuse (rather than a positive case that there are such infringements/ misuse) which it is pleaded "is properly to be inferred from the following facts and matters". There are then set out some 8 sub-paragraphs lettered from (a) to (g). However, some of those so-called "facts and matters" are themselves only established if further inferences are first drawn.

54. Thus the first matter, in paragraph (a), is that it took a very short time to create an Exxeta/E-Star product akin to Joule compared with the time that it took to develop Joule. But that depends upon an inference that it took this very short time ("Trayport infers the development of the [E-Star product] took less than 2 years").

55. Similarly, sub-paragraph (g) relies upon the "targeted recruitment" of former employees of Trayport as earlier particularised. However, the earlier particulars pleaded refer to 4 employees having left Trayport following Mr Schmid leaving Trayport and the "understanding" of Trayport being that they are now employed by Exxeta/E-Star. The dates that the employees are said to have commenced employment with E-Star are not known but it is the understanding of Trayport that they perform substantially similar roles to those that they performed when employed by Trayport, "In the premises, Trayport infers that …one or more of the Defendants encouraged the Trayport leavers to resign" which is said to be properly inferred from the close relationship between Mr Schmid and the employees; the timing of their resignations and the similar nature of their roles at Trayport and at E-Star.

56. I accept the submission of [counsel for the third defendant Karsten Schmid] that in considering whether a particular claim has a real prospect of success, I have to consider the issue of inferences carefully and that as regards a particular inference, I must consider two questions:

(1) Whether there is a sufficient evidential basis for each of the pleaded facts said to support the inference such that there is a real prospect of each pleaded fact being proven at trial; and

(2) As regards those facts where a real prospect of success at trial is made out, is there a real prospect of those facts taken together being sufficient to support the inference that the court is invited to draw.

57. In this respect I was referred to UKIP v Braine & Ors [2020] EWHC 1794 (QB), [2020] WL 03662051 at [25]. I refer particularly to sub-paragraph (d) on the inference point. Sub-paragraph (e) deals with a separate point, which is the point that the court must, before deciding whether a claim has no real prospect of success, be alive to the evidence that can reasonably be expected to be available at trial whilst not allowing that consideration to act as a charter to plead an unsustainable case but to say that it may become sustainable after disclosure (what used sometime to be referred to as "fishing"). Sub-paragraphs (d) and (e) are as follows:

"(d) Fourth, where a party invites the court to draw inferences of arguable wrongdoing, there must be a sufficient prior pleaded factual foundation supporting such inferences. That foundation might come, for example, from expert evidence in a data breach case, even if in draft form prior to formal permission under CPR 35. The foundation for an inference might also come from the inherent probabilities that certain events would have followed upon other events which have been established as arguable by evidence. Naturally, a court will be less willing to draw an inference that there was arguable serious wrongdoing involving, for example, acts of dishonesty, concealment or bad faith than more neutral conclusions.

(e) Fifth, in reaching its interlocutory conclusions the court must take into account not only the evidence actually placed before it on the application for summary judgment but the evidence that can reasonably be expected to be available at trial (a point specifically emphasised by Counsel for the Claimant). Again, this point only goes so far and should not be interpreted as a charter to plead a factual case which it is said may become sustainable when disclosure is given."

As regards sub-paragraph (e), Saini J made a similar point in the same case at paragraph [99], when determining the application:

"[99] … One cannot plead an unsustainable case and then pray in aid potential disclosure to save it from summary judgment and striking out"

58. As regards the drawing of inferences, I also refer again to Elite Property Holdings Ltd v Barclays Bank plc [2019] EWCA Civ 204 at [41], which paragraph I have cited earlier in this judgment.

59. At some points in his submissions [counsel for the claimant Trayport] seemed to me to come perilously close to saying that, because Trayport did not know what had happened, matters that gave rise to suspicion were enough to found a case with a real prospect of success and that an absence of pleading or evidence at this stage was quite in order because without disclosure the claimant could not make good its suspicions. This he seemed to say, at least at some point, was a different practice to the norm reflected by e.g. paragraph [99] of Saini J's judgment in the UKIP Ltd v Braine case, cited earlier in this judgment.

60. At the end of the day however, I did not understand him to disagree with what I regard as the orthodox position regarding what is required for an order for service out as regards the merits test. First, that any cause of action must be adequately pleaded and secondly, that the pleading must be sufficiently backed up by evidence so as to raise a case with a real prospect of success. As regards pleading, I understood his position, on analysis, to be no different to what was said by Arnold LJ in Celgard, LLC v Shenzhen Senior Technology Material Co Ltd [2020] EWCA Civ 1293; [2021] FSR 1 at [48]:

"I do not wish in any way to diminish the importance of proper particulars of trade secrets being provided in cases of this nature. What amounts to sufficient particularisation must depend on the circumstances of the individual case, however. Furthermore, a lesser degree of particularisation may be acceptable at the outset of a case than at later stages of the case. Still further, I accept that it is relevant to take into account the claimant's ability to provide further particulars, and the extent to which the claimant has been hampered by obstructiveness, or at least non-cooperation, on the part of the defendant. In the circumstances of the present case, I consider that Celgard has done enough for now, although it will undoubtedly have to give further particulars at a later stage."

61. In short, mere suspicion is not enough. In the case of inference there must a belief in the truth of facts that give rise to a pleaded inference, which facts have a real prospect of success of being established and, if established, the inference must have a real prospect of success of being drawn and must be believed as being the appropriate inference. It is not enough simply to plead or say: "we are very suspicious, it may be that the various elements of a cause of action can be made out but it may be that they cannot, we have no idea but once we have disclosure we will find out and the point will either be clear or we will be clear about what inferences we are inviting the court to draw and which have a real prospect of success, and we will then plead our position."

62. Finally, in this context, I should mention the issue of amendment. I will come back to the point later, but as I see the dispute between the parties it is a dispute as to whether, if the PoC are defective in any way, permission to amend should be given (and leave to serve out left to stand) or whether the Claimant has had opportunities to amend and, not having taken them, it is now too late to allow permission to amend to be granted and to "save" any permission for serve out in relation to a defectively pleaded case. As to this, there are some minor tidying up points that I would allow permission to amend for. However, where it is unclear precisely what amendment should be made to establish a properly pleaded cause of action I would either have to adjourn the questions before me until I had a properly pleaded statement of case on the relevant issue or I would set aside leave and leave it to the claimant to re-apply both to amend and for permission to serve out. Given the history of this matter, I would incline to the latter course.

“the appropriate forum”

63. There was no real dispute as to the applicable law and principles.

64. In summary:

(1) The burden is on the Claimant to persuade the court that England is clearly the appropriate forum (Spiliada Maritime Corp v Cansulex Ltd [1987] AC 460 (HL) at 481D; Altimo Holdings v Kyrgyz Mobil [2011] UKPC 7 at [88]. This burden follows the principle that the courts must be "exceedingly careful" in deciding whether it "ought to put a foreigner, who owes no allegiance here, to the inconvenience and annoyance of being brought to contest his rights in this country".

(2) The "appropriate forum" is that in which "the case may be tried more suitably for the interests of all the parties and the ends of justice" (Spiliada at 476C; Lungowe v Vedanta Resources plc [2019] UKSC 20; [2020] AC 1045 at [66]).

(3) CPR r6.37(3) puts the test in terms of permission not being granted unless the court is satisfied that England and Wales is "the proper place in which to bring the claim" but this formulation simply encapsulates the "appropriate forum" test (Lungowe at [66]).

(4) In determining what is clearly the appropriate forum, the court conducts a summary examination of connecting factors to determine the forum with the "most real and substantial connection", including matters of practical convenience (such as accessibility to courts for parties and witnesses and the availability of a common language so as to minimise the expense and potential for distortion involved in translation of evidence) and also such matters as the system of law which will be applied to decide issues, and the place where the wrongful acts or omissions occurred and the place where the harm occurred (Spiliada at 478A-B; Lungowe at [66]).

(5) The court's decision is an evaluative one. It is not an exercise of discretion (VTB Capital pc v Nutritek International Corp [2013] 2 AC 337 at [97], [156]).'

Exposition - Full and fair disclosure

Separately, the Judge in Trayport went on to consider the principles attached to the obligation to give full and frank disclosure, when making a without notice application (here, to obtain permission to serve out of the jurisdiction). For those interested, this is set out in a footnote[2].

[1] In Trayport Ltd v E-Star Trading GmbH [2026] EWHC 164 (Ch) ('Trayport'), HHJ Davis-White KC (sitting as a Judge of the Chancery Division) said, at paragraphs 10 to 12:

'I shall deal with the particular causes of action relied upon by the Claimant in more detail later in this judgment. However, it is useful to give a flavour of them now. In broad terms the main claims are in respect of alleged misuse of/access to the Claimant's software, contained in or forming a software platform called "Joule". I explain Joule in more detail later on this judgment but, put very broadly, it is a software platform containing a number of databases and which provides customers of Trayport, who buy access to it, dealing and trading information. It also enables customers to make deals in the wholesale energy commodities markets. Different customers may have different levels of access to Joule. The Joule platform is alleged to contain matters that are the intellectual property of Trayport, protected by, among others, copyright law, trade secrets law, database law, the law of confidentiality and so on.

The misuse of Trayport's information is largely pleaded as a matter of inference. The overall primary misuse identified is the use of confidential information belonging to Trayport in the creation of a new software platform belonging to and marketed by E-Star which is said to replicate functions of Joule and which, in effect, competes with it (see e.g. paragraph 91 of the Particulars of Claim ("PoC") (the "Copying Case"). One of the matters upon which such inference is based is a series of alleged accesses said to have been made by employees of the First and Second Defendants, E-Star and Exxeta (together the "corporate Defendants") to the Trayport platform by using individual accounts granted to the corporate Defendants (or its employees) by customers of Trayport, but in alleged breach by those customers of the agreements with Trayport under which the customer is entitled to access and interact with (and download information from) Joule.

Again only in broad terms, and without breaking down which claims are brought against which Defendant, the PoC assert copyright infringement; database infringement; breach of a non-disclosure agreement; breach by Mr Schmid of employment and termination of employment contracts; inducing breach of contracts by customers of Trayport; procurement of breach by Mr Schmid of his employment/termination of employment contracts; breach of equitable duties of confidence; breach of the Trade Secrets (Enforcement, etc) Regulations 2018; infringement of the Trade Marks Act 1994; vicarious liability of E-Star and Exxeta for the unlawful acts of others (including the Fourth Defendant) and, for good measure, unlawful means conspiracy. There are two further discrete claims which are that, in breach of an employment contract and a termination agreement relating to such employment with Trayport, Mr Schmid, now a managing director of E-Star, wrongly solicited employees of Trayport to join E-Star and/or has gone to work with a competitor to Trayport, namely E-Star, during a period when he was prohibited by such contracts from working for competitors. Other aspects of these contracts are also relied upon as mirroring other direct claims against Mr Schmid (e.g. for breach of equitable duties of confidence).'

[2] In Trayport Ltd v E-Star Trading GmbH [2026] EWHC 164 (Ch), HHJ Davis-White KC (sitting as a Judge of the Chancery Division) said, at paragraphs 65 to 70:

'A useful starting point is the judgment of Carr J (as she then was) in Tugushev v Orlov (No 2) [2019] EWHC 2031 (Comm) at [7]-[8]:

"[7] The law is non-contentious. The following general principles can be distilled from the relevant authorities by way of summary as follows:

i) The duty of an applicant for a without notice injunction is to make full and accurate disclosure of all material facts and to draw the court's attention to significant factual, legal and procedural aspects of the case;

ii) It is a high duty and of the first importance to ensure the integrity of the court's process. It is the necessary corollary of the court being prepared to depart from the principle that it will hear both sides before reaching a decision, a basic principle of fairness. Derogation from that principle is an exceptional course adopted in cases of extreme urgency or the need for secrecy. The court must be able to rely on the party who appears alone to present the argument in a way which is not merely designed to promote its own interests but in a fair and even-handed manner, drawing attention to evidence and arguments which it can reasonably anticipate the absent party would wish to make;

iii) Full disclosure must be linked with fair presentation. The judge must be able to have complete confidence in the thoroughness and objectivity of those presenting the case for the applicant. Thus, for example, it is not sufficient merely to exhibit numerous documents;

iv) An applicant must make proper enquiries before making the application. He must investigate the cause of action asserted and the facts relied on before identifying and addressing any likely defences. The duty to disclose extends to matters of which the applicant would have been aware had reasonable enquiries been made. The urgency of a particular case may make it necessary for evidence to be in a less tidy or complete form than is desirable. But no amount of urgency or practical difficulty can justify a failure to identify the relevant cause of action and principal facts to be relied on;

v) Material facts are those which it is material for the judge to know in dealing with the application as made. The duty requires an applicant to make the court aware of the issues likely to arise and the possible difficulties in the claim, but need not extend to a detailed analysis of every possible point which may arise. It extends to matters of intention and for example to disclosure of related proceedings in another jurisdiction;

vi) Where facts are material in the broad sense, there will be degrees of relevance and a due sense of proportion must be kept. Sensible limits have to be drawn, particularly in more complex and heavy commercial cases where the opportunity to raise arguments about non-disclosure will be all the greater. The question is not whether the evidence in support could have been improved (or one to be approached with the benefit of hindsight). The primary question is whether in all the circumstances its effect was such as to mislead the court in any material respect;

vii) A defendant must identify clearly the alleged failures, rather than adopt a scatter gun approach. A dispute about full and frank disclosure should not be allowed to turn into a minitrial of the merits;

viii) In general terms it is inappropriate to seek to set aside a freezing order for nondisclosure where proof of non-disclosure depends on proof of facts which are themselves in issue in the action, unless the facts are truly so plain that they can be readily and summarily established, otherwise the application to set aside the freezing order is liable to become a form of preliminary trial in which the judge is asked to make findings (albeit provisionally) on issues which should be more properly reserved for the trial itself;

ix) If material non-disclosure is established, the court will be astute to ensure that a claimant who obtains injunctive relief without full disclosure is deprived of any advantage he may thereby have derived;

x) Whether or not the non-disclosure was innocent is an important consideration, but not necessarily decisive. Immediate discharge (without renewal) is likely to be the court's starting point, at least when the failure is substantial or deliberate. It has been said on more than one occasion that it will only be in exceptional circumstances in cases of deliberate non-disclosure or misrepresentation that an order would not be discharged;

xi) The court will discharge the order even if the order would still have been made had the relevant matter(s) been brought to its attention at the without notice hearing. This is a penal approach and intentionally so, by way of deterrent to ensure that applicants in future abide by their duties;

xii) The court nevertheless has a discretion to continue the injunction (or impose a fresh injunction) despite a failure to disclose. Although the discretion should be exercised sparingly, the overriding consideration will always be the interests of justice. Such consideration will include examination of i) the importance of the facts not disclosed to the issues before the judge ii) the need to encourage proper compliance with the duty of full and frank disclosure and to deter noncompliance iii) whether or not and to what extent the failure was culpable iv) the injustice to a claimant which may occur if an order is discharged leaving a defendant free to dissipate assets, although a strong case on the merits will never be a good excuse for a failure to disclose material facts;

xiii) The interests of justice may sometimes require that a freezing order be continued and that a failure of disclosure can be marked in some other way, for example by a suitable costs order. The court thus has at its disposal a range of options in the event of non-disclosure.

[8] There is no suggestion that the same principles do not apply to a without notice application for permission to serve out as they do on a without notice application for a freezing order (as confirmed for example in PJSC Commercial Bank PrivatBank v Kolomoisky and others (supra) at [169] and Sloutsker v Romanova [2015] EWHC 545 (QB) at [52])."

In Derma Med Ltd v Ally [2024] EWCA Civ 175, the principles stated by Carr J in the Tugushev case were approved. It was noted at paragraph [30] that:

"[30] Although this was said in the context of an application for a freezing order, the principles are of general application."

Of course, the principles have to be applied in the particular context in which they arise. For example, what is material in one context may not be material in another, or may not be as significant; similarly the response of the court will depend on applying the relevant principles to the particular context. As Toulson J (as he then was) said in MRG v Engelhard Metals Japan [2003] EWHC 3218 (Comm); [2004] 1 Lloyd's Rep 731 at [25]-[26]:

"[25] Materiality therefore depends in every case on the nature of the application and the matters relevant to be known by the Judge when hearing it. I was referred to a number of statements on the duty of disclosure in the context of applications for freezing injunctions. In such cases the Court is being asked to make an order of an exceptional kind, prohibiting or restricting a defendant's use of its own assets before any adjudication has been made against it. Because of its draconian nature, it is a jurisdiction which requires great caution and a wide range of factors may have a bearing on the Court's decision.

[26] An application for permission to serve out of the jurisdiction is of a very different nature. The general principles about disclosure on without notice applications still apply, but the context is different. The focus of the inquiry is on whether the Court should assume jurisdiction over a dispute. The Court needs to be satisfied that there is a dispute properly to be heard (i.e. that there is a serious issue to be tried); that there is a good arguable case that the Court has jurisdiction to hear it; and that England is clearly the appropriate forum. Beyond that, the Court is not concerned with the merits of the case."

(see also Payabi v Amstel Shipping Corporation [1992] QB 907 at 918).

Before me, [counsel for the first and second defendant] having relied in his skeleton argument upon Toulson J's statement in paragraph [26] that I have just cited, to the effect that the general principles are the same but that they have to be applied in the particular context, submitted orally that Toulson J had said that the principles differed as between freezing injunction applications and service out applications. I do not read Toulson J as saying that, quite the contrary. However, if there was any doubt about the correct position that has since been clarified by cases referred to and as summarised in Tugashev and by the Court of Appeal in the Derma Med case.

I was also referred to a number of the cases illustrating the application of the relevant principles. In particular I was referred to Crossroads Corporate Finance (UK) LLP v Ontario Management Ltd [2025] EWHC 1011 (Comm); Almegha, v Al-Sanea [2025] EWHC 322 (Ch) and Marinkakis v Karipidis [2025] EWHC 13 (KB) in particular showing the need for paper applications to clearly flag matters up (and that doing so in a Skeleton argument will do) and not bury them in the papers.

Finally, in the context of the differences in type and consequence of innocent and non-innocent non-disclosure and, even where innocent, serious and non- serious non-disclosure, and the issue of the court's overall approach, as dealt with in paragraph 7(ix) to (xiii) of the Tugashev case, I was referred to Borelli v Otaibi [2024] ILPr 31, Banca Turco Romana SA v Cortuk [2018] EWHC 662 Comm), National Bank Trust v Yurov [2016] EWHC 1913 (Comm), Wragg v Opel Automobile GmBH [2024] EWHC 1138 (KB). In addition I was referred to paragraph 34(1) of the Banca Turco case where it was said that "if an applicant who is guilty of non-disclosure wishes the court to treat it as innocent, it is incumbent upon it to explain how it came about." Possibly in light of the latter point, at the break in the hearing I made an order permitting the Claimant to file and serve further evidence dealing with limited topics, one of which was the allegation of breach of the duty of full and frank disclosure regarding the Employment Agreement and Termination Agreement. Mr Harris' fourth witness statement dealt with that (among other matters).'

[3] In State Oil Co of Azerbaijan v Mansimov [2026] EWHC 2102 (Comm), Birt J heard a defendants' application for an order, setting aside an earlier (Jacobs J's) order, which granted the claimants permission for the claim to be served out of the jurisdiction. Under the heading 'application', Birt J said, at paragraphs 18 and 19:

'The defendants now apply to set aside the order of Jacobs J giving permission for service out of the jurisdiction. That order also provided for alternative service on each of the defendants, but no separate point is taken in the application in relation to that part of the order.

There was no dispute between the parties that, in order for the claimants to obtain permission to serve the defendants out of the jurisdiction they must satisfy the court that:

i) There is a serious issue to be tried on the merits of the claim, i.e. the claim has to have a real, as opposed to a fanciful, prospect of success.

ii) There is a good arguable case that the claim falls within one or more of the jurisdictional gateways in paragraph 3.1 of PD6B.

iii) In all the circumstances England is clearly or distinctly the appropriate forum for the trial of the dispute and that the court ought to exercise its discretion to permit service of the proceedings out of the jurisdiction. This is reflected in CPR 6.37(3).

See AK Investment CJSC v Kyrgyz Mobil Tel Limited [2011] UKPC 7, [2012] 1 WLR 1804 at paragraph 71; Brownlie v Four Seasons Holdings Inc [2017] UKSC 80, [2018] 1 WLR 192 at paragraph 3.'

[4] In Intralinks Inc v Nexans SA [2026] EWHC 2355 (Comm) ('Intralinks'), in the London Circuit Commercial Court, Thomas Raphael KC (sitting as a Deputy Judge of the High Court) had before him a case where:

(a) a claimant (Intralinks) had issued a claim for disputed sums under a contract; 

(b) the claimant had sought, and obtained (paragraph 11), permission to serve out of the jurisdiction (paragraph 10). The claimant argued that jurisdiction could be established under Gateway 6(c) and Gateway 7. It also argued that England and Wales (“England” for brevity) was the proper place to bring the claim (paragraph 10). 

The defendant (Nexans) challenged the jurisdiction of the Court by application under CPR Part 11. The defendant: (a) denied that a valid jurisdictional gateway was satisfied; and (b) said it had not been shown that England was the proper place to bring the claim (paragraph 12). 

Under the heading 'Legal Structure', the Judge said, at paragraphs 15 to 19:

'The framework for whether the Court has jurisdiction over a foreign defendant who is not present in England is set out in the rules for service of proceedings abroad contained in CPR 6.36 and 6.37 and CPR PD 6B, §3.

To justify the Court assuming jurisdiction, Intralinks must show: that (a) there is a “serious issue to be tried”; (b) one of the gateways set out in PB 6B applies for each claim (CPR 6.36); (c) England is “the proper place in which to bring the claim” (CPR 6.37(3)); (d) in all the circumstances the Court ought to exercise its discretion to permit service out of the jurisdiction. See Altimo Holdings and Investment v Kyrgz Mobil Tel [2011] UKPC 7, [71].

The burden of proof of establishing each requirement is on Intralinks: Altimo, [71]. Nexans did not dispute that there was a serious issue to be tried, nor did it dispute that, if (b) and (c) were satisfied, this would be an appropriate case for the discretion to permit service out to be exercised.

To show that a gateway applies, Intralinks must establish a “good arguable case” that the conditions of the gateway are satisfied. This requires, where there are factual disputes as to the satisfaction of the relevant conditions, that provided the Court can reach a reliable assessment (which it can here), Intralinks must show it has “the better of the argument” on the material available, “having regard to the limitations which an interlocutory process imposes”. The test is “context-specific and ‘flexible’”, and does not turn on satisfying the civil standard at trial, of proof on the balance of probabilities. In expressing a view for the purposes of jurisdiction, “the court must be astute not to express any view on the ultimate merits of the case”. See Kaefer Aislamentos v AMS Drilling Mexico [2019] 1 WLR 3514 (CA), [73]-[80]. However, if a question of law goes to the existence of jurisdiction, such as the meaning of a gateway, the Court will normally decide the question, instead of assessing whether the claimant has a good arguable case on it: Altimo, [81].

To satisfy the requirement that England is the “proper place” to bring the claim, Intralinks must show that England was “clearly” the “appropriate” forum to hear the claim: Spiliada Maritime v Cansulex [1987] AC 460, 481D-E. This is the question of “forum conveniens”, explored below.'

Later, under the heading 'The Law on Appropriate Forum' and subheading 'General Principles', the Judge said, at at paragraph 114 to 134:

'114. English law has adopted the doctrine of forum conveniens with the enthusiasm of a convert. Yet the chain of cases which achieved this, starting with The Atlantic Star [1974] AC 436, and passing through MacShannon v Rock Wear Glass [1978] AC 795, involved a gradual and sometimes painful process of development (Spiliada 475D-476B). It is only with Lord Goff’s luminous judgment in Spiliada that the modern doctrine of forum conveniens take form. So judgments on this topic between 1973 and 1987 must be handled with care.

115. The heart of the law should be taken from Spiliada. The basic principle is:

It is proper therefore to regard the classic statement of Lord Kinnear in Sim v. Robinow (1892) 19 R. 665 as expressing the principle now applicable in both jurisdictions. He said, at p. 668:

"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."

(p. 474C-D)

116. Lord Goff added an important clarification, sometimes forgotten:

I feel bound to say that I doubt whether the Latin tag forum non conveniens is apt to describe this principle. For the question is not one of convenience, but of the suitability or appropriateness of the relevant jurisdiction. However the Latin tag (sometimes expressed as forum non conveniens and sometimes as forum conveniens) is so widely used to describe the principle, not only in England and Scotland, but in other Commonwealth jurisdictions and in the United States, that it is probably sensible to retain it. But it is most important not to allow it to mislead us into thinking that the question at issue is one of "mere practical convenience." Such a suggestion was emphatically rejected by Lord Kinnear in Sim v. Robinow, 19 R. 665, 668, and by Lord Dunedin, Lord Shaw of Dunfermline and Lord Sumner in the Société du Gaz case, 1926 S.C.(H.L.) 13, 18, 19, and 22 respectively. Lord Dunedin, with reference to the expressions forum non competens and forum non conveniens, said, at p. 18:

"In my view, 'competent' is just as bad a translation for 'competens' as 'convenient' is for 'conveniens.' The proper translation for these Latin words, so far as this plea is concerned, is 'appropriate.'"

Lord Sumner referred to a phrase used by Lord Cowan in Clements v. Macaulay (1866) 4 Macph. 583, 594, viz. "more convenient and preferable for securing the ends of justice," and said, at p. 22:

"one cannot think of convenience apart from the convenience of the pursuer or the defender or the court, and the convenience of all these three, as the cases show, is of little, if any, importance. If you read it as 'more convenient, that is to say, preferable, for securing the ends of justice,' I think the true meaning of the doctrine is arrived at. The object, under the words 'forum non conveniens' is to find that forum which is the more suitable for the ends of justice, and is preferable because pursuit of the litigation in that forum is more likely to secure those ends."

In the light of these authoritative statements of the Scottish doctrine, I cannot help thinking that it is wiser to avoid use of the word "convenience" and to refer rather, as Lord Dunedin did, to the appropriate forum.

(pp. 474-475)

117. Turning then to “How the principle is applied in cases of stay of proceedings”:

(a) The basic principle is that a stay will only be granted on the ground of forum non conveniens where the court is satisfied that there is some other available forum, having competent jurisdiction, which is the appropriate forum for the trial of the action, i.e. in which the case may be tried more suitably for the interests of all the parties and the ends of justice.

…

(d) Since the question is whether there exists some other forum which is clearly more appropriate for the trial of the action, the court will look first to see what factors there are which point in the direction of another forum. These are the factors which Lord Diplock described, in MacShannon's [1978] A.C. 795 case, 812, as indicating that justice can be done in the other forum at "substantially less inconvenience or expense." Having regard to the anxiety expressed in your Lordships' House in the Société du Gaz case, 1926 S.C. (H.L.) 13 concerning the H [SIC] use of the word "convenience" in this context, I respectfully consider that it may be more desirable, now that the English and Scottish principles are regarded as being the same, to adopt the expression used by my noble and learned friend, Lord Keith of Kinkel, in The Abidin Daver [1984] A.C. 398, 415, when he referred to the "natural forum" as being "that with which the action had the most real and substantial connection." So it is for connecting factors in this sense that the court must first look; and these will include not only factors affecting convenience or expense (such as availability of witnesses), but also other factors such as the law governing the relevant transaction (as to which see Credit Chimique v. James Scott Engineering Group Ltd., 1982 S.L.T. 131), and the places where the parties respectively reside or carry on business.

(pp. 476-477)

118. The above describes the “first stage” of Spiliada. Under the second stage:

(f) If however the court concludes at that stage that there is some other available forum which prima facie is clearly more appropriate for the trial of the action, it will ordinarily grant a stay unless there are circumstances by reason of which justice requires that a stay should nevertheless not be granted. In this inquiry, the court will consider all the circumstances of the case, including circumstances which go beyond those taken into account when considering connecting factors with other jurisdictions. One such factor can be the fact, if established objectively by cogent evidence, that the plaintiff will not obtain justice in the foreign jurisdiction; see the The Abidin Daver [1984] A.C. 398, 411, per Lord Diplock, a passage which now makes plain that, on this inquiry, the burden of proof shifts to the plaintiff.

(478C-E; the duplicate “the The” is in the original)

119. Turning then to “How the principle is applied in cases where the court exercises its discretionary power under R.S.C., Ord. 11” (now CPR 6.36-7):

.. the question in both groups of cases must be, at bottom, that expressed by Lord Kinnear in Sim v. Robinow, 19 R. 665, 668, viz. to identify the forum in which the case can be suitably tried for the interests of all the parties and for the ends of justice. That being said, it is desirable to identify the distinction between the two groups of cases. These, as I see it, are threefold. The first is that, as Lord Wilberforce indicated, in the Order 11 cases the burden of proof rests on the plaintiff, whereas in the forum non conveniens cases that burden rests on the defendant. A second, and more fundamental, point of distinction (from which the first point of distinction in fact flows) is that in the Order 11 cases the plaintiff is seeking to persuade the court to exercise its discretionary power to permit service on the defendant outside the jurisdiction. Statutory authority has specified the particular circumstances in which that power may be exercised, but leaves it to the court to decide whether to exercise its discretionary power in a particular case, while providing that leave shall not be granted "unless it shall be made sufficiently to appear to the court that the case is a proper one for service out of the jurisdiction:" see R.S.C., Ord. 11, r.4(2).

…

The effect is, not merely that the burden of proof rests on the plaintiff to persuade the court that England is the appropriate forum for the trial of the action, but that he has to show that this is clearly so. In other words, the burden is, quite simply, the obverse of that applicable where a stay is sought of proceedings started in this country as of right.

…

It is also significant to observe that the circumstances specified in Order 11, r.1(1), as those in which the court may exercise its discretion to grant leave to serve proceedings on the defendant outside the jurisdiction, are of great variety, ranging from cases where, one would have thought, the discretion would normally be exercised in favour of granting leave (e.g., where the relief sought is an injunction ordering the defendant to do or refrain from doing something within the jurisdiction) to cases where the grant of leave is far more problematical. In addition, the importance to be attached to any particular ground invoked by the plaintiff may vary from case to case. For example, the fact that English law is the putative proper law of the contract may be of very great importance (as in B.P. Exploration Co. (Libya) Ltd. v. Hunt [1976] 1 W.L.R. 788, where, in my opinion, Kerr J. rightly granted leave to serve proceedings on the defendant out of the jurisdiction); or it may be of little importance as seen in the context of the whole case. In these circumstances, it is, in my judgment, necessary to include both the residence or place of business of the defendant and the relevant ground invoked by the plaintiff as factors to be considered by the court when deciding whether to exercise its discretion to grant leave; but, in so doing, the court should give to such factors the weight which, in all the circumstances of the case, it considers to be appropriate.

(pp. 480-482)

120. It may assist to tease out two of the strands of this reasoning.

121. First, the analysis of connecting factors is aimed at establishing what is the appropriate forum to try the case. It is not a blind assessment of factual connections. Legal connections can be central. Thus the “law governing the relevant transaction”, “could be of very great importance”.

122. Second, for the same reason, the assessment of connecting factors is not solely a question of “convenience or expense”. What matters is how the factors make a forum “more suitable for the ends of justice”. So the relevance of location should not solely be assessed by reference to practical advantages. It can be distinct to issues of convenience and expense (Spiliada 478A-B).

123. As Popplewell LJ explained in Limbu v Dyson [2024] EWCA Civ 1564: “The domicile of the parties … is, however, an important factor. The reason it is an important connecting factor in relation to jurisdiction is because presence here is the basis for establishing the court’s jurisdiction, and domicile here connotes a degree of permanence and allegiance to the country’s institutions, including its courts …” That was said when considering the relevance of domicile in the context of service within the jurisdiction, but point that the location of the parties may matter for forum because it “connotes a degree of permanence and allegiance to the country’s institutions, including its courts” is of general significance. People are usually more likely to understand and be comfortable with their home country’s legal system compared to more alien systems.

124. It is worth adding a clarification about Popplewell LJ’s use of “domicile”. For appropriate forum, as Spiliada tells us, it is generally the place where the parties substantially “reside” or “carry on business” (478B), rather than technical domicile, that has weight. In Spiliada 481F, Lord Goff said that a technical residence like a tax haven would have little weight. Yet it was central to his approach that a real, substantial location would ordinarily have weight (Macsteel Commercial Holdings v Thermasteel [1996] CLC 1403, 1406-1407).

Specific factors

125. The relevance and weight of particular connecting factors depends on their interplay with the issues in the particular case, and is for the Judge to assess in all the circumstances (see Novus Aviation v Onur Air [2009] EWCA Civ 122 at [79], per Lawrence Collins LJ, and Spiliada at 481G, 482A). Extrapolations from the fact-specific reasoning in other decisions should therefore be handled with care. However, there is useful learning on central factors.

Applicable Law

126. There have been differences of emphasis as to the role and weight of the applicable law. But the essential modern principle is stated in Spiliada. The law governing the relevant transaction is generally a relevant connecting factor. Its importance depends on the circumstances, but it may be of very great importance: Spiliada 478B, 481G-H; Novus [74], [77], [79].

127. In VTB v Nutritek [2013] 2 AC 337, Lord Mance observed in a tort case: “The governing law, which is here English, is in general terms a positive factor in favour of trial in England, because it is generally preferable, other things being equal, that a case should be tried in the country whose law applies. However, that factor is of particular force if issues of law are likely to be important and if there is evidence of relevant differences in the legal principles or rules applicable to such issues in the two countries in contention as the appropriate forum” [46]. (See also Lord Clarke in the minority at [218]-[219]). An express contractual choice of law may confer additional weight to the law chosen.

128. The English courts, and the French courts, are well able to apply foreign law, and the English commercial courts have considerable experience in doing so. Yet a national court will in general be better placed to apply its own law than foreign law, in particular where complex legal issues arise: see Novus, [39]-[40]

129. In Macsteel, Sir Thomas Bingham MR observed that a choice of law “is a factor of importance, in particular, where there is some distinction or some arguable distinction between the law of the two competing jurisdictions.” Yet in the case before him “there is no suggestion in the evidence that the law of England and the law of Ontario are in any way different on the apparently straightforward issues raised by this dispute.” (p. 1407). Yet it was an error of principle to conflate a choice of law with a choice of jurisdiction. A jurisdiction clause is of very great weight, but a choice of law is not an implied choice of jurisdiction. By choosing English law but not including an English jurisdiction clause the parties have deliberately decided not to agree positively on English jurisdiction (pp. 1407-1408, also Millett LJ at p. 1408). They might even not have wanted English jurisdiction; although the more natural inference is usually that they have just left the question of jurisdiction open.

130. In The Channel Ranger [2014] 1 Lloyds Rep 337, [61], Males J said:

As for the significance of the express choice of English law, such a choice is capable of being a factor of significant and even decisive weight, particularly if the foreign court’s application of a different law would or might lead to a different result as that would be to deprive the claimant of the benefit of its bargain: The Lucky Lady [2013] EWHC 328 (Comm), [2013] 2 Lloyd’s Rep 104 at [28], where Andrew Smith J reviewed the applicable authorities, including the comments of Lord Mance in VTB Capital Plc v Nutritek International Corporation [2013] UKSC 5, [2013] 1 Lloyd’s Rep 466 at [46] …

131. Males J thought that, if the claim was to proceed in Morocco, it was likely that Moroccan law would be applied which would likely produce a different result. So “the need to litigate in a forum which would apply English law as the law expressly chosen” outweighed the location of witnesses and evidence: [62], [64].

132. In Novus, where there were disputes about formation, Aikens J had reasoned that because the issues were likely to include disputes as to the application of English contract law, the putative proper law of the contract, the choice of English law was a significant factor. The English courts would be better able to deal with those issues than Turkish courts: [39]-[40]. On appeal, Lawrence Collins LJ held this contained no error in principle [81]. He added that a choice of English law could be of particular significance if “the foreign forum, notwithstanding the express choice of English law, may instead apply its own law” [78].

133. In Macsteel, there is an observation by Millett LJ that the choice of English law was “not an insignificant factor and it could be decisive if the issue were otherwise nicely balanced as between England and some other jurisdiction. But I do not see how it can be decisive where the issue is not so balanced …” (p. 1409). This might suggest choice of law has limited force. But it was obiter, and not reflected in Sir Thomas Bingham LJ’s judgment with which Millett LJ agreed (Pill LJ agreed with both). It is inconsistent with Spiliada, and has not been picked up in the case law. When in Novus, [74], [79], Lawrence Collins LJ considered Macsteel, he did not pick up on these observations. Instead he took the Spiliada approach that the significance of the choice of law depends on the circumstances and issues, but could be of very great importance.

Lurssen

134. Nexans relied on FR Lurssen Werft v Halle [2009] EWHC 2607 (Comm). Simon J observed on forum:

(2) Where the only basis relied on by a claimant to establish jurisdiction is that the claim is made in respect of a contract governed by English law, particular caution will be required, and the burden on the claimant of showing good reasons justifying service out of the jurisdiction is a ‘particularly heavy one’: Ilyssia Compania Naviera SA v Bamaodah (The Elli 2) [1985] 1 Lloyd's Rep 107 at p.113, The Spiliada at p.479- 480 and Novus Aviation v. Onur Air Tasimacilik AS [2009] EWCA Civ 122, Lawrence Collins LJ at [32].

(3) Although different expressions have been used to characterise the nature of the jurisdiction, it is clearly recognised that it is an exceptional course to require a foreigner to litigate in the English Court purely on the basis that English law is the Governing law of the contract. It may be a less exceptional course, as Mr Thomas acknowledged, where there has been a choice of law under the Rome Convention.'

The Judge in Intralinks then said, at paragraphs 135 to 147:

'135. [Counsel for Nexans] relied on this to contend that, where Gateway 6(c) is the “only basis”, a claimant had to satisfy a “heavy burden”, and thus a higher threshold. However, in my view, these observations do not further Nexans’ case, and are not the law.

136. To begin with, such reasoning would only it seems apply where the sole gateway of jurisdiction is Gateway 6(c), or perhaps where English applicable law is the sole factual basis for saying England is the appropriate. Yet that is not so here. Intralinks has established two gateways, not just 6(c), and (as discussed below) relies on connecting factors beyond English law. Further, Simon J allowed the position might be different for an express choice of law, which is the case here.

137. Further, such dividing lines would be arbitrary. The gateways give a range of different connections. Some have lesser weight in themselves than choice of law. In principle, it does not seem justified to say that using the “English law” gateway alone should impose an unusual burden. The straightforward principle which the modern case law generally adopts is that, if any gateway is passed, the Court then considers all relevant connecting factors and gives them their appropriate weight, when applying the single test of whether England is the most appropriate forum. In doing so, a choice of English law can be a very significant factor.

138. Simon J cited The Elli 2 [1985] 1 Lloyds Rep 107, Spiliada, and Novus. But the archaeology of these cases reveals Simon J’s propositions are not now the law.

a) Their historical roots lie in Amin Rasheed v Kuwait [1984] AC 50. Lord Diplock described the English law gateway in Order 11 r.1(1)(f)(iii), as “exorbitant”. So leave to serve out under it should be exercised “with circumspection” (p. 65) and “The exorbitance of the jurisdiction sought to be invoked where reliance is based exclusively upon r. 1(1)(f)(iii) is an important factor to be placed in the balance against granting leave.” (p. 68). This could be outweighed if “justice could not be obtained by him in the alternative forum, or could only be obtained at excessive cost, delay or inconvenience”. But Lord Wilberforce adopted a different principle, holding in more modern terms that the correct approach was to look at all the connecting factors and ask whether there were good reasons to permit service out (p. 72D-F). The conflict between Lord Diplock’s approach and Lord Wilberforce’s then played out in the subsequent case law.

b) In The Elli 2, still before Spiliada, the focus was on whether Lord Diplock’s exceptions were the only possibilities. Ackner LJ concluded not: “Lord Diplock was emphasizing that where exclusive reliance is placed upon r. 1(1)(f)(iii) then the burden of showing good reasons justifying service out of the jurisdiction is a particularly heavy one, and he illustrated this by the examples which he gave of situations which were capable of taking tipping the balance. Thus constructed … there is no conflict between Lord Diplock’s statement and that of Lord Wilberforce …” (113rhc). By this he dissolved some of the rigidity of Lord Diplock’s approach but in doing so transmuted it into his “heavy burden” Yet when applying the law to the facts, he did not apply any constraining burden, and accepted the judge had been entitled to give conclude that the choice of English law, where the relevant issues were likely to turn on complex points of English law, was decisive. May LJ (pp. 118-119) took still a more circumspect approach to Lord Diplock’s observations, describing them as dicta and not a statute. The ‘heavy burden” language was not used. May LJ said merely that jurisdiction based solely on a choice of English law should be exercised with “considerable caution”.

c) In Spiliada, Lord Goff made clear that the old law was being departed from; and that he needed to resolve the differences between Lord Wilberforce and Lord Diplock in Amin Rasheed (473C-E, 475F-H). Turning to Elli 2, he interpreted it as adopting Lord Wilberforce’s reasoning not Lord Diplock’s (480C), and viewed Lord Wilberforce’s approach as close to the correct principle, but clarified the true modern principle as now being the doctrine of forum conveniens derived from Scottish law (480G-H), whose single core concept was to ask where the matter can most suitably be tried in the interests of justice. He cast doubt on Lord Diplock’s use of the word “exorbitant” as old fashioned (481E). Turning to gateways and connecting factors, he concluded: “the importance to be attached to any particular ground invoked by the claimant may vary from case to case”, including choice of English law, which “may be of very great importance”, but “the Court should give to all such factors the weight which, in the circumstances of the case, it considers appropriate” (481-482). Lord Goff does this elegantly, deftly and politely, but the result is Lord Diplock’s approach in Amin Rasheed is deliberately displaced, and so is any doctrine of “heavy burden” from Elli 2, or any particular “circumspection” in the use of the English law gateway. While Spiliada is a judgment of the Privy Council, it is accepted it states modern English law.

d) In the modern judgments of the Supreme Court, it has been made further clear that treating the gateways as exorbitant and governed by “muscular presumptions” against service out of the jurisdiction is an out-of-date approach: see Abela v Baadarani [2013] 1 WLR 2043 (SC), [53]; Brownlie v Four Seasons [2018] 1 WLR 192 (SC), [31].

e) Finally, [32] of Novus (CA) which Simon J also cites is not part of the Court of Appeal’s reasoning, but a paraphrase of Aikens J’s judgment, recording him as adopting Ackner LJ’s “heavy burden” approach. Yet that was not picked up by the Court of Appeal. At [73]-[74] Lawrence Collins LJ did not follow Lord Diplock’s reasoning in Amin Rasheed, and instead adopted the approach in Spiliada. This departs not only from Amin Rasheed, but also from the “heavy burden” approach in The Elli 2.

f) Thus, Spiliada and Novus, although cited by Simon J, in fact contradict the propositions quoted from Lurssen above at (2)-(3).

g) The modern cases do not adopt any logic of “heavy burden” and this aspect of Lurssen has not been followed. Indeed, in Lurssen itself, Simon J went on to weigh the importance of the choice of English law in a conventional way, and conclude that it was a key factor in showing England was the most appropriate forum: [53].

139. I conclude that the correct approach is stated in Spiliada. The test for forum is simply to ask whether England is clearly the most appropriate forum, taking into account all relevant connecting factors. There is no different burden or test, simply because Gateway 6(c) is the gateway relied on. The weight for forum of English law being the applicable law depends on all the facts and circumstances. But it can be very important.

The location and language of documents; the location and nationality of witnesses

140. The case law has explored the weight to be given to the language of documents and the nationality of witnesses. Again, it must be borne in mind the relevance of such factors is for the Judge in each case to assess in all the circumstances. However, the way in which this is done in other cases is instructive.

141. First, since the use of English in international commercial transactions is ubiquitous, the sole fact that documentation or negotiations are in English has been said to be not of great weight. See Novus [80]. Yet in other cases, the language of documents has been given greater weight. Even in an age of improved machine translation the need to engage with foreign language documents increases cost, complexity, and the risk of error. A judge has an advantage in understanding documents in her native tongue. The importance of the language of documents increases where issues may turn on the meaning of language. See Novus [80] referring to The Magnum [1989] 1 Lloyds Rep 47 (CA), 51; Joyvio Group Co Ltd v Moreno [2024] EWHC 2493, [87]-[88] (Nigel Cooper KC).

142. Second, it has been said that the location of documents and witnesses may matter less in modern circumstances than previously, given the easy use, storage and transferability of electronic documents, the ease of modern travel, and the availability of video-link: Cockerill J in Al Mana Lifestyle Trading v United Fidelity [2022] EWHC 2049 (Comm), [98]. This is particularly so for the physical location of documents: Joyvio at [87]. Nevertheless, the location of evidence and witnesses can remain relevant, as Spiliada envisages: see VTB at [62]. Modern technology shrinks distance but it cannot fully substitute for physical presence. For example, evidence in person is superior to examination through video-link.

143. In addition, the physical location of witnesses is not the only aspect of “where they are from” which matters. First, the native tongues and linguistic skills of the likely witnesses are relevant. Witnesses generally give better evidence in a language they are comfortable with, while the use of interpreters is costly, generally awkward and prone to error: see Joyvio at [87]; and VTB at [62]. So it is a factor in favour of a forum that the language of its courts is the one in which most of the likely witnesses are most comfortable.

144. Second, even independent of questions of language, as already discussed, people are usually more likely to understand and be comfortable with their home country’s legal system, or similar legal systems, compared to more alien systems. So the national culture of witnesses and their likely relative familiarity with the alternative possible legal systems can be a relevant connecting factor.

Overlapping foreign proceedings

145. The existence of overlapping proceedings in a foreign forum is a relevant connecting factor. Their force depends on the circumstances. This was common ground between the parties, although key authority was not cited. It is helpful to refer to the well-known leading judgment of Lord Goff in De Dampierre v De Dampierre [1988] AC 92, 108B-D, in which he held that overlapping foreign proceedings should be addressed within the Spiliada framework, and observed:

… the existence of such proceedings may, depending on the circumstances, be relevant to the inquiry. Sometimes they may be of no relevance at all, for example, if one party has commenced the proceedings for the purpose of demonstrating the existence of a competing jurisdiction, or the proceedings have not passed beyond the stage of the initiating process. But if, for example, genuine proceedings have been started and have not merely been started but have developed to the stage where they have had some impact upon the dispute between the parties, especially if such impact is likely to have a continuing effect, then this may be a relevant factor to be taken into account when considering whether the foreign jurisdiction provides the appropriate forum for the resolution of the dispute between the parties.

146. Other factors affecting the weight to be given to the foreign proceedings will include, I consider, the degree of overlap, the extent of substantial priority in time, the risks of a multiplicity of proceedings, and the risk of conflicting judgments.

147. In The Channel Ranger, Males J reasoned on the facts before him, at [60]:

While there have been cases in which multiplicity of proceedings has been a decisive factor against English jurisdiction, I regard the existence of proceedings in Morocco in this case as being of no weight (and therefore need not consider further the issue about the extent to which I am permitted to take those proceedings into account). They were commenced only after the defendants were served with the present proceedings, and well after the receiver at any rate was aware of these proceedings. If this court was the appropriate forum at the time when permission was granted for service out of the jurisdiction, at which time the Moroccan proceedings did not exist, I do not see how the defendants’ own decision to bring proceedings in Morocco (ex hypothesi not the appropriate forum in the absence of those proceedings) can alter this assessment. If the existence of proceedings in two different jurisdictions is a problem for the defendants, they have the remedy in their own hands, namely to discontinue the proceedings in Morocco and contest the merits here.'

On the facts, the Judge concluded that the clamant had '...satisfied Gateways 6(c) and 7 and shown that England is the proper place to bring the claim.' (paragraph 14). The Defendant's (Nexans') challenge, under CPR Part 11, to the jurisdiction of the (English) Court, failed. [bold added]
