“171. Where the appellate test has been met, it has generally been because the Judge lost sight of the reasonable necessity test by placing undue emphasis on her “level playing field” and “information asymmetry” criteria. I can agree with her that informational asymmetry is a relevant factor, but the quest for a perfectly mirroring evidential equality should not obscure the need for proper restraint, parsimony and proportionality in disclosure. It is likely that the departure from proportionate disclosure stems from the breadth of information sought by the claimant. It was put by Mr Shear of his solicitors (B1474) in this way: “the Claimant seeks an order that the Defendant provide specific disclosure of documents that are highly relevant to the issues on the Jurisdiction Application, which are required to fully understand and interrogate the Defendant’s position, and which are required for the fair resolution of the Jurisdiction application.” 172. This theme was taken up by the claimant’s counsel at the hearing below in their skeleton (para 22): “However, in order for Sheikh Alesayi to be able to interrogate fully the Bank’s blanket denials, he needs to be provided with the documents that go to those issues. It is for this reason that disclosure is required underCPR 31.12 .” 173. I accept the appellant’s submission that this approach went too far and the Judge in part acceded to it erroneously. To restate: at the next turn lies a jurisdiction challenge hearing, not a “mini-trial” (in VTB Capital terms), let alone a full one (if happens at all, about which I also refrain from commenting on). That hearing will be determined using a modestly low threshold, as the Judge recognised. But words are insufficient. The acid test is the disclosure she ordered. I judge that she failed at times to give sufficient weight to the legally confined nature of the issue that had to be decided. The “equal footing” factor in the overriding objective is not unqualified. It is vitally tempered by the words “as far as is practicable”
“It is well established as a matter of principle that costs orders should be made on a ‘pay as you go’ basis, as between the parties in relation to interim and interlocutory applications.”
“(8) Where the court orders a party to pay costs subject to detailed assessment, it will order that party to pay a reasonable sum on account of costs, unless there is good reason not to do so.”
