“Any person served with the claim form who wishes to take part in the planning statutory review must file an acknowledgement of service in the relevant practice form in accordance with paragraphs 5.3 to 5.6.”
“6.1 Where a person served with the claim form has failed to file an acknowledgement of service … rule 8.4 does not apply and that person - (a) may not take part in a hearing to decide whether permission should be given unless the court allows him to do so; but (b) provided that person complies with paragraphs 12.1 to 12.3 or any other direction of the court regarding the filing and service of - (i) detailed grounds for contesting the claim or supporting it on additional grounds; and (ii) any written evidence, may take part in the hearing of the planning statutory review. 6.2 Where that person takes part in the hearing of the planning statutory review, the court may take the failure to file an acknowledgement of service into account when deciding what order to make about costs.”
“The position is different where an appeal on costs raises a question of law. Appeals to the House of Lords, or in more recent times to this court, which are purely on costs have long been discouraged, as a general rule, and will rarely meet the court’s central criterion for the grant of permission to appeal, namely that the appeal must ‘raise an arguable point of law of general public importance’: UKSCPractice Direction 3 , paragraph 3.3.3. Nevertheless, where permission to appeal has been granted, the court will intervene if an error of law is established.”
“The House will be astute to ensure that unnecessary costs are not incurred. Where there is multiple representation, the losing party will not normally be required to pay more than one set of costs, unless the recovery of further costs is justified in the circumstances of the particular case. … What then is the proper approach? As in all questions to do with costs, the fundamental rule is that there are no rules. Costs are always in the discretion of the court, and a practice, however widespread and longstanding, must never be allowed to harden into a rule. …” (Emphasis added)

(3) The time limits under this rule may not be extended by agreement between the parties. (4) The acknowledgement of service - (a) must - (i) where the person filing it intends to contest the claim, set out a summary of his grounds for doing so; and (ia) where the person filing it intends to contest the application for permission on the basis that it is highly likely that the outcome for the claimant would not have been substantially different if the conduct complained of had not occurred, set out a summary of the grounds for doing so; and (ii) state the name and address of any person the person filing it considers to be an interested party; and (b) may include or be accompanied by an application for directions.

“(1) to assist claimants with a speedy and relatively inexpensive determination by the court of the arguability of their claims; and (2) to prompt defendants - public authorities - to give early consideration to and, where appropriate, to fulfil their public duties.”
“8.5 Neither the defendant nor any interested party need attend a hearing on the question of permission unless the court directs otherwise. 8.6 Where the defendant or any party does attend a hearing, the court will not generally make an order for costs against the claimant.”
“The effect of In re Leach, certainly in a case to which the pre-action protocol applies and where a defendant or other interested party has complied with it, is that a successful defendant or other party at the permission stage who has filed an acknowledgement of service pursuant toCPR rule 54.8 should generally recover the costs of doing so from the claimant, whether or not he attends any permission hearing.”
