“8. In response to these submissions, my assessment of the position is as follows: (1) as regards the question of success or failure in relation to the Claimants’ application for injunctive relief against Persons Unknown, the Claimants were not successful in all respects but were significantly more successful than the Sixth and Seventh Defendants in relation to the arguments which were put before the court; (2) if the Claimants’ application for injunctive relief had sought that relief against the Sixth and Seventh Defendants, there would have been a case for giving the Claimants a part of their costs against the Sixth and Seventh Defendants and there would not have been a case for giving the Sixth and Seventh Defendants any part of their costs against the Claimants; (3) in view of the fact that the Claimants’ application was for injunctive relief against Persons Unknown, the Claimants had to come to court in any event to obtain that relief; (4) the opposition presented by the Sixth and Seventh Defendants to the Claimants’ application lengthened the hearing (as compared with a case where no one appeared on behalf of the Defendants) but the participation of the Sixth and Seventh Defendants was of assistance to the court in a case of public importance; (5) the Claimants are not entitled to their costs of their application for injunctive relief against the Sixth and Seventh Defendants (and they do not seek them) and the Sixth Defendant is not entitled to his costs against the Claimants of that application (and he does not seek them) and I consider that the Seventh Defendant is not in principle (subject to the possibility considered and rejected in (6) below) entitled to his costs against the Claimants of that application; (6) I do not consider that the Seventh Defendant’s criticisms of the Claimants’ conduct of the application are well founded and they do not persuade me to make an order for costs in favour of the Seventh Defendant; (7) as regards the Seventh Defendants’ claim for his costs of his application of6 September 2017 , I do not consider that that application succeeded on12 September 2017 when the court continued the earlier order with some modifications; (8) as regards the Claimants’ application for their costs against the Sixth Defendant of his application, there is a case for saying that the Claimants should have those costs; in so far as the Sixth Defendant sought a variation of the earlier order it is not clear that it was necessary to apply for a variation of the earlier order as distinct from opposing the further order being sought by the Claimants; further, in so far as the Sixth Defendant’s application was based on his contention that the Claimants had been in breach of their duty of candour on the earlier ex parte application, that contention failed; however, on balance, I consider that the right approach to the Sixth Defendant’s contention as to the duty of candour is that it should not be separated out as an issue which should carry an order for costs but instead that contention should be considered as one of the many issues which had to be determined and it should be dealt with in the same way as all of the issues arising; (9) as regards the Claimants’ application for their costs against the Seventh Defendant of his application, I take the same view as in the case of the Sixth Defendant. 9. Taking all of the above matters into account, I have reached the conclusion that the fair result is that there should be no order for costs in respect of the Claimants’ application of31 July 2017 and no orders for costs in respect of the Sixth and Seventh Defendants’ applications of6 September 2017 .”
