"119 I am in something of a fog as to the difference between an "explication" and a "gloss"
‘But I see no reason why that test [viz that which was applicable in the jurisdictional gateway context] should apply to freezing injunctions where ex hypothesi (or subject to any jurisdictional challenge) the defendant is properly before the court.’
‘It is true that in adopting the good arguable test Mustill J was following the decision of Lord Denning in Rasu Maritima S.A v Perusahaan Pertambangan Minyak Dan Gas Bumi Begara (The Pertamina)[1978] QB 644 , and Lord Denning had in turn adopted it in the context of a freezing order because he thought that the jurisdiction test was appropriate, at least where the case involved a foreign defendant (see p.661G). But there have been developments in the law relating to jurisdiction since, and although a claimant in both jurisdiction and freezing order cases must establish a "good arguable case", the policy considerations are different in the two situations and it is far from obvious that this inherently flexible concept must have the same meaning in each context. Indeed, even in jurisdiction cases the good arguable case test only goes to the question whether the claim falls within one of the grounds set out inPD6B para.3.1. We are concerned with the merits of the case, and so far as they are concerned, a claimant in a jurisdiction case has only to show that there is a serious issue to be tried: see Seaconsar Ltd v Bank Markazi [1994] 1 A.C.438, 457 per Lord Goff of Chieveley.’
‘The test on the strength of the merits needed for Mareva relief is not the test used to ascertain whether the claimant has brought itself within a jurisdictional gateway. [footnote 147] That test is to be applied at the time that proceedings are commenced because depending on whether it is satisfied there either was or was not jurisdiction at that time, and there does not cease to be jurisdiction because of later developments in the facts. The test used for jurisdiction challenges has been considered in a series of cases and is a tri-part test … In Mareva cases the all-important question is whether, at the time of the hearing and determination of the application for the injunction, in the circumstances of the case, it is “just and convenient” to grant it. Because of the intrusion into the defendant’s affairs resulting from a Mareva injunction there is a threshold test on the strength required on the merits, which is a “good arguable case”. A requirement that a court must form the provisional view that the claimant will probably succeed at trial would be inconsistent with an approach which enables the court to achieve “its great object viz abstaining from expressing any opinion upon the merits of the case until the hearing”. Nevertheless, the court will take into account the apparent strength or weakness of the respective cases in order to decide whether the claimant’s case, on the merits, is sufficiently strong to reach the threshold, and this will include assessing the apparent plausibility of statements in affidavits.’
‘This test is easier for the claimant to pass than is the test applicable in the case of injunctions which will finally dispose of an action … and easier than the “good arguable case” test applicable on challenges to the jurisdiction of the English courts (see … Kaefer Aislamientos SA de CV v AMS Drilling Mexico SA de CV[2019] EWCA Civ 10 and Kazakhstan Kagazy Plc v Arip[2014] EWCA Civ 381 at [25]).’
‘The test of "good arguable case" is well-known in the context, for example, of freezing injunctions. The authorities in this area are summarised in Gee: Commercial Injunctions 7th edition, paragraphs 12-032 – 12-033 drawing on classic statements of Mustill J. It is not enough to show an arguable case, namely one which a competent advocate can get on its feet. Something markedly better than that is required, even if it cannot be said with confidence that the plaintiff is more likely to be right than wrong. It is therefore not necessary for the applicant to have a case with a better than 50 per cent chance of success.’
