“…. The whole purpose of requiring that leave should first be obtained to make the application for judicial review would be defeated if the court were to go into the matter in any depth at that stage. If, on a quick perusal of the material then available, the court thinks that it discloses what might on further consideration turn out to be an arguable case in favour of granting to the applicant the relief claimed, it ought, in the exercise of a judicial discretion, to give him leave to apply for that relief. …”
“In practice the requirement, far from being an impediment to the individual litigant, can even be to his advantage since it enables a litigant expeditiously and cheaply to obtain the view of a High Court judge on the merits of his application.”
“We are satisfied that there are features of public law litigation which distinguish it from private law civil and family litigation … The important difference here is that there is a public interest in the elucidation of public law by the higher courts in addition to the interests of the individual parties. One should not therefore necessarily expect identical principles to govern the incidence of costs in public law cases …”
“77. Such an approach seems to me to accord with public policy in providing ready access to the courts by individuals or bodies seeking relief from and/or to draw attention to actual or threatened transgressions of the law by public bodies, whilst, in exceptional cases protecting those bodies and the public that funds them from unnecessary, burdensome and costly substantive litigation. If properly and consistently applied by the courts, I can see nothing about it that would, as Mr. Steel suggested, undermine the fairness and probity of judicial review as a means of control of the administration or run contrary to Article 6.1 of the European Convention of Human Rights, Lord Woolf's Civil Justice Reforms or the adoption of them in this context in the Bowman Report.”
“The costs of dealing with a threatened claim are generally irrecoverable, unless a claim is made, gets permission and eventually the claimant loses.”
“…. In considering whether, and in what circumstances, there should be a departure from the basic rule that costs follow the event in public interest challenge cases, in my view it is important to have in mind the rationale for that basic rule, and that it is for the applicants to show why, exceptionally, there should be a departure from it.”
