"Accordingly, this is in my view a good example of why exceptionally the court should retain a power to review a final order." 27. For HSBC Mr Turlough Stone submitted that the effect of Roult v North WestStrategic Health Authority was to impose a simple jurisdictional ban on the application of Part 3.1(7) to final orders. By way of fallback he submitted that, in any event, the 'judge misled' category of case for revocation did not apply merely because, through lack of legal representation and advice, a litigant failed to deploy available material on the earlier occasion which he wished, after obtaining advice, to deploy at a later stage. For that purpose he relied principally upon Morgan J's analysis in Simms v Carr. 28. For his part Mr Adair for Mr Kojima submitted first that Roult was not a decision about jurisdiction, and left open Peter Smith J's analysis that exceptional circumstances might justify the revocation or variation of a final order under Part 3.1(7). As for the 'judge misled' category of circumstance calling for revocation, he submitted that where a litigant was unable to obtain professional advice, his failure to advance relevant material on the earlier occasion could not fairly be said to have been a matter of choice. 29. My conclusions are as follows. First, although Mr Stone has in his favour the description in its headnote of the Court of Appeal's decision in Roult as one about jurisdiction, I do not read the judgment of Hughes LJ (with which Carnwath and Smith LJJ agreed) as going quite that far. Nonetheless it does in the passage which I have quoted, clearly establish that, to the extent that there exists any jurisdiction in the court to review its own final order, that is not to be justified on the alternative grounds first enunciated by Patten J, and approved in Collier v Williams, in the context of procedural or other non-final orders. 30. In my judgment once the court has finally determined a case, or part of a case, considerations of the type first identified by Patten J in Lloyds v Ager-Hanssen will generally be displaced by the much larger, if not indeed overriding, public interest in finality, subject of course to the dissatisfied party's qualified right of appeal. 31. Mr Adair very sensibly took no technical point that the District Judge's Order was not in form a final order, accepting that it did finally dispose of the part of HSBC 's claim which Mr Kojima had admitted, subject only to appeal. Nonetheless he did submit that it was not the type of final order which ought properly to attract the public interest in finality. There was in his submission all the difference between a final order on the merits made after the trial of an issue, and a final order by way of judgment on admissions, since in the latter category the first instance court would never have investigated the entitlement of the claimant to that part of the claim which the defendant had admitted. Furthermore, he submitted, Roult v North West StrategicHealth Authority was about a final order approving a settlement between the parties which, evidently, the Court of Appeal had regarded as a powerful factor against allowing scope for revocation or variation at first instance. He relied also on the fact that, in Edwards v Golding, the Court of Appeal had not been dissuaded from upholding the revocation of an order for joinder of a defendant by the fact that the claimant had then obtained a final order against him by way of judgment in default, which was also set aside. 32. While I recognise the force of Mr Adair's point that the finality principle is more obviously justifiable where a final order follows a full trial, or for that matter a settlement between the parties, than where it merely gives effect to an admission, I am not persuaded that a judgment on admissions is not a judgment on the merits. Still less is it to be equated with a default judgment, as to which, regardless of its finality, there exists a well-established and distinct power to set aside, now to be found inCPR Part 13 . Judgment on admissions is governed byCPR Part 14 , specifically by Rule 14.3. Judgment is not obtained by some automatic process, but by application under Part 23 and, under rule 14.3(2): "
