If you have received a judicial review claim that falls within the Planning Court, Form N462PC is the document you use to respond. It is the Acknowledgment of Service tailored to planning matters, and it is completed by the defendant, meaning the party the claim has been brought against.
Getting this form right matters because it sets out whether you intend to contest the claim, on what grounds, and what procedural directions you would like the court to consider. The form also captures information about anyone else with an interest in the outcome, and it fixes the address where future court papers should be sent.
This guide walks through each section of N462PC, explains what goes where, and flags the points that often trip defendants up the first time they file.
What this document is
Form N462PC is a specialist version of the standard judicial review Acknowledgment of Service, designed for claims allocated to the Planning Court. The Planning Court handles judicial reviews and statutory challenges involving planning permissions, compulsory purchase orders, highways decisions, environmental assessments, and related matters.
When a claimant issues proceedings, the defendant is required to file an Acknowledgment of Service within a set period after being served with the claim form. That document is N462PC. It tells the court whether the defendant accepts or resists the claim, names any other parties who ought to be involved, and can include submissions on how the case should proceed.
For court and tribunal defendants filing a procedural submission only, the form allows that to be indicated briefly. The form also addresses environmental claims that fall under the Aarhus Convention, where specific costs protections may apply. Filing N462PC properly is a procedural step rather than the substantive defence, but the content often shapes how permission for judicial review is decided.
How to use this document
Section A: state your position. This is where the defendant indicates whether they intend to contest the claim, contest only part of it, or not contest it at all. If any part of the claim is being resisted, Sections B, C and D also need to be completed. If the claim is not being contested, the defendant can skip to Section F and sign off.
Section B: interested parties and contact details. Use this section to name anyone else who has an interest in the outcome, such as a person, organisation, or public body likely to be affected if the decision under challenge is overturned. There is also space to add a telephone number, an email address, and additional address lines where relevant for service of documents.
Section C: grounds for contesting. Set out the summary grounds for resisting the claim here. This is not the full defence, but it should give the court a clear picture of why permission should be refused or why the challenge should fail. If you are a court or tribunal defendant filing only a formal submission rather than a substantive response, simply indicate that in this section.
Section D: directions sought. Use this space to request any procedural directions you would like the court to make, for example about case management, expedition, or the scope of documents. Keep requests focused and explain briefly why each one would assist the efficient handling of the claim within the Planning Court's timetable.
Section E: Aarhus Convention claims. This section only applies where the claimant has marked the case as an Aarhus Convention claim, which concerns environmental matters and carries specific costs protection. If you dispute that the claim qualifies, set out your reasons here. Alternatively, if you want the court to vary the costs limits under CPR 45.43(2), explain why.
Section F: statement of truth and service address. The defendant, or someone authorised on their behalf, signs a statement of truth confirming that the facts stated in the form are true and that all relevant matters have been disclosed. Provide an address within the jurisdiction where court documents can be served, and include counsel's details if you have already instructed a barrister.
Form N462PC is completed by the defendant in a judicial review claim that has been issued in or transferred to the Planning Court. The defendant is the public body, authority, or other party whose decision or conduct is being challenged. Interested parties named in the claim typically use their own Acknowledgment of Service, though practice can vary. If you are unsure which role applies, it is worth checking the sealed claim form carefully.
Q What is the deadline for filing N462PC?
An Acknowledgment of Service in judicial review must generally be filed within 21 days of service of the claim form, with copies served on the claimant and any other parties within a further short period. Planning Court cases follow the same general framework under the Civil Procedure Rules, though specific case directions may apply. Missing the deadline can mean you lose the right to take part in the permission stage, so diarise it early.
Q What is the difference between N462 and N462PC?
N462 is the standard Acknowledgment of Service for judicial review claims in the Administrative Court. N462PC is the Planning Court equivalent, used for claims involving planning, environmental, and related public law issues that have been allocated to that specialist court. The structure is similar, but N462PC reflects the particular procedures and costs rules that apply to Planning Court work, including Aarhus Convention provisions.
Q What is an Aarhus Convention claim?
An Aarhus Convention claim is a judicial review concerning decisions covered by the Aarhus Convention, which protects public rights to participate in environmental matters and to access the courts without being exposed to prohibitive costs. Where a claim qualifies, costs recoverable against an unsuccessful claimant are capped. Defendants who disagree that a claim qualifies can say so in Section E of N462PC and set out their reasons.
Q Do I need to file a full defence with N462PC?
No. The Acknowledgment of Service is a summary document rather than a full defence. You set out your grounds for contesting the claim in outline in Section C, but detailed written submissions are filed later if permission for judicial review is granted. That said, the summary grounds often carry significant weight at the permission stage, so they should be clear, focused, and address the main points in the claim.
Q Can I file N462PC without a solicitor?
There is no rule requiring legal representation to complete the form. However, judicial review is a technical area of public law, and Planning Court cases often involve complex issues of statutory interpretation, environmental regulation, and procedural costs rules. Many defendants, particularly public authorities, instruct counsel or in-house legal teams. If you are an individual or small organisation named as a defendant, taking early guidance is usually sensible.
Q What happens after the Acknowledgment of Service is filed?
Once N462PC is filed, the court considers whether to grant permission for judicial review, usually on the papers initially. The summary grounds in Section C form part of that decision. If permission is granted, the case moves towards a substantive hearing and the defendant files detailed grounds of resistance and evidence. If permission is refused, the claimant may request an oral reconsideration, and the process continues from there.
Planning Court deadlines are tight and the summary grounds you set out can shape whether permission is granted. An experienced legal adviser can help you think through your response based on what you describe on the call.
