Hilltop Experiences Ltd, R (On the Application Of) v Norfolk County Council
England and Wales Court of Appeal (Civil Division)
May 6, 2026
Smart Summary (Beta)
Summary of Judgment: Appellant v Respondent (Court of Appeal, 06/05/2026)
Factual and Procedural Background
The Appellant operates an outdoor education business on a circa 33-acre site in The City that serves approximately 10,000 children annually, including around 1,000 children with special educational needs or disabilities. The Appellant's premises lie close to an existing Household Waste Recycling Centre ("HWRC"). The Respondent (the County Planning Authority) granted planning permission on 5 June 2024 for a replacement HWRC on a nearby larger site. The Interested Party (the statutory Waste Disposal Authority) promoted the replacement HWRC following a service review which identified capacity constraints at the existing facility.
The Appellant sought judicial review of the Respondent's grant of planning permission. Lieven J (Judge Lieven) dismissed the claim by order dated 9 July 2025. The Appellant obtained permission to appeal on two inter-related grounds and challenges to the judge's case management decisions about admitting new evidence. The Appellant sought to adduce evidence after the first-instance hearing relating to a potential alternative site (a quarry located outside the National Landscape designation and approximately 600 metres from the proposed HWRC site) and applied to amend its grounds to rely on a claimed material error of fact by the Respondent in not having considered that site.
Legal Issues Presented
- Whether the Respondent's consideration of alternative sites for the proposed HWRC was legally adequate in circumstances where it did not consider a particular quarry site outside the National Landscape designation.
- Whether the first-instance judge erred in refusing to admit new evidence and to allow amendment of the Appellant's grounds based on an alleged material error of fact in the Respondent's consideration of alternatives.
Arguments of the Parties
Appellant's Arguments
- The Respondent's site selection assessment was deficient because it failed to consider a viable alternative site outside the National Landscape designation (the quarry approximately 600 metres away), and the officer's report was materially misleading in that respect.
- The judge below should have admitted the late evidence and allowed amendment to plead a material error of fact because the new material showed the Respondent had made an established factual error which materially affected the decision.
Respondent's Arguments
- The late evidence should be excluded as it was unnecessary and, in any event, immaterial to the planning judgment reached by the Respondent; the officer's recommendation expressly acknowledged the limited site-selection exercise and treated the possibility of other sites as weighing against the proposal.
- Even if there had been some misunderstanding by the case officer about which quarry was being referenced in earlier material, any error was not an established material factual error within the public law error-of-fact jurisdiction and would not have changed the planning balance.

Court's Reasoning and Analysis
The court (Judge Dove, with Judges Miles and Zacaroli agreeing) proceeded as follows:
- Statutory framework: The court began from section 70(2) of the Town and Country Planning Act 1990 and section 38(6) of the Planning and Compulsory Purchase Act 2004, which require the authority to have regard to the development plan and to determine in accordance with it unless material considerations indicate otherwise.
- Mandatory status of alternatives under policy: The court identified that development plan policy EN1 (the policy protecting the National Landscape designation) expressly required consideration of alternative sites where a proposal is within the National Landscape; thus availability of alternatives was a legally mandatory material consideration in this case.
- Standard of review: Where the evaluation of alternatives is a matter of planning judgment, the court will only intervene if the approach of the local planning authority is Wednesbury irrational. The court applied authorities (including Samuel Smith and Derbyshire Dales) to distinguish between matters that are merely potentially relevant and those the statute or policy compels the decision-maker to consider.
- Error of fact analysis: Applying the criteria in E, the court analysed two suggested factual errors: (a) that the officer misunderstood which quarry was referred to in the applicant's site-selection material, and (b) that the Respondent failed to consider the nearby quarry as an available site outside the National Landscape. The court concluded the alleged errors did not constitute an "established" factual mistake of the kind required by E (noting the contemporaneous evidence showed absence of engagement from the landowner during the site-selection period) and, crucially, that any misunderstanding did not play a material part in the decision-maker's reasoning.
- Officer's report and Mansell principles: The court examined whether the officer's report materially misled members under Mansell. The officer's report expressly acknowledged the limitations of the site-selection exercise and explicitly treated the possibility of other suitable sites outside the National Landscape as weighing against the proposal. The recommendation therefore already took that possibility into account in the planning balance. On a fair reading, the report did not materially or significantly mislead members about the availability of alternatives.
- Planning judgment and materiality: Because the officer had identified the potential availability of alternative sites and had recommended permission only after concluding the public interest and other benefits outweighed the identified conflict with policy, the court concluded that the absence of specific mention of the particular quarry did not alter the planning balance or the legality of the decision. The court therefore found no legal error either by way of mistake of fact or by material misdirection in the officer's report.
- Case management: Given the substantive conclusions, the court upheld the first-instance judge's case-management decisions refusing to admit the late evidence and to permit amendment of the pleadings as the evidence was immaterial to the lawful basis of the decision.
Holding and Implications
APPEAL DISMISSED
Holding: The Court of Appeal dismissed the Appellant's appeal, concluding there was no error of law in the Respondent's grant of planning permission: (i) the Respondent lawfully treated availability of alternative sites as a material consideration required by development plan policy, (ii) the alleged factual errors did not meet the threshold for the error-of-fact jurisdiction, and (iii) the officer's report did not materially mislead the committee.
Implications: The direct effect is that the planning permission for the replacement HWRC remains valid and the Appellant's judicial review challenge fails. The court's decision turns on the application of established public law and planning principles to the facts of this case; the court did not purport to establish a novel legal precedent beyond applying existing authorities.
