Factual and Procedural Background
This is an appeal by the Appellant against an order of Judge Lang dismissing a judicial review challenging Respondent A's approval of a reserved matters application dated 4 March 2025. The reserved matters related to a housing development for up to 170 dwellings and associated infrastructure at [Number] Main Street in The City. All planning applications were made by Respondent B. Respondent B obtained outline permission (ref. 16/00151/AOP) on 24 March 2022 for up to 170 dwellings with all matters reserved except access, subject to conditions including condition 1 (reserved matters to be submitted and approved), condition 2 (time limit for submission of reserved matters), and condition 13 (requiring a foul water drainage scheme including a wastewater treatment capacity assessment and that no part of the development be occupied until any required wastewater upgrades had been agreed with and completed by Company A).
Respondent B submitted a reserved matters application on 25 May 2023 (ref. 23/01636/ADP) for 163 dwellings (later described as 153) seeking approval of appearance, landscaping, layout and scale and discharge of some conditions. Correspondence with Company A in 2023–24 showed the receiving Facility A lacked capacity and any upgrades depended on Company A's investment programme. Respondent B applied under section 73 to vary condition 13 to allow details to be submitted prior to occupation; that section 73 permission was granted by Respondent A on 10 December 2024 (ref. 24/02780/VRC) varying the timing of required wastewater upgrades so they must be completed prior to occupation.
The reserved matters application was considered by Respondent A's committee on 13 February 2025 and approved on 4 March 2025 (ref. 23/01636/ADP), described as "as varied by application 24/02780/VRC (condition 13 ... approved on 10 December 2024)". The approval included detailed drawings, conditions and an informative noting that the reserved matters permission was to be read alongside the outline and the section 73 permission.
Legal Issues Presented
- Whether the reserved matters approval was unlawful because the application was substantially altered so as to omit or ignore the requirements of condition 13 (foul water drainage scheme) which, the Appellant contends, were temporally linked to condition 1 and the time limit in condition 2.
- Whether Respondent A lawfully considered and determined the reserved matters application "with reference to" the section 73 permission, effectively switching the application from the outline permission to the section 73 permission after the time for submitting reserved matters under the section 73 permission had expired.
Arguments of the Parties
Appellant's Arguments
- The drafting of the outline permission linked condition 13 to condition 1 such that the requirements of condition 13 were temporally tied to the time limit in condition 2; drainage details therefore had to be submitted within the reserved matters timescale and were not separable.
- The reserved matters application was substantially altered by excluding the required programme/specification for upgrades to Facility A; approving the application without that information unlawfully ignored a key part of condition 13.
- It was unlawful for Respondent A to treat the reserved matters application as being considered with reference to the section 73 permission or effectively to switch the parent permission to the section 73 permission when the time for submitting reserved matters under that permission had expired.
Respondents' Arguments
- Condition 13 does not constitute a reserved matter under the statutory definition; drainage details are not one of the five reserved matters and, as established in Murray, drainage requirements are to be satisfied before commencement rather than within the reserved matters timescale.
- The reserved matters application did not, as a matter of fact, seek to discharge condition 13 and Judge Lang correctly found that fact; there was therefore no substantial alteration of the application.
- It was open to Respondent A to consider the reserved matters application with reference to the section 73 permission; in any event the decision notice and accompanying materials show the reserved matters were approved pursuant to the original outline permission and not under the section 73 permission.
- Permitting a different construction (as the Appellant proposes) would produce absurd practical consequences by forcing fresh full applications unnecessarily.

Court's Reasoning and Analysis
The court set out statutory background: sections 57, 70, 91 and 92 of the Town and Country Planning Act 1990 and the Development Management Procedure Order 2015 definitions of reserved matters. It analysed the content and phrasing of the outline permission, condition 1 (reserved matters), condition 2 (time limit), and condition 13 (foul water drainage scheme requiring a wastewater treatment capacity assessment and that no part of the development be occupied until required upgrades agreed and completed with Company A).
The court applied established authorities (notably Pye, Powergen, Trump, Lambeth and DB Symmetry) to its interpretive task: ask what a reasonable reader would understand the documents to mean in context. It accepted Murray's authority that drainage is not a reserved matter and that the timing for provision of drainage details is prior to commencement rather than governed by the reserved matters submission period.
On construction, the court concluded that condition 13 cross-references condition 1 only to require that the four reserved matters take account of onsite foul water drainage design; it did not convert condition 13 into a reserved matter subject to condition 2's time limit. The court found as a matter of fact (a finding unassailable on appeal) that the reserved matters application did not seek to discharge condition 13 in full and that the submitted drawings contained the onsite foul water drainage proposals required for the reserved matters. The offsite upgrades to Facility A remained matters to be agreed and completed with Company A prior to occupation (as varied by the section 73 permission).
Regarding the amendment to the application description adding "as varied by application 24/02780/VRC ... approved on 10 December 2024", the court held that this was at most a factual clarification and not a substantive amendment transferring the application to be under the section 73 permission. The reasonable reader, reading the reserved matters decision (headed with the original reserved matters reference) would conclude the approval was made pursuant to the original outline permission. The informative in the decision notice reading the reserved matters permission alongside the outline and section 73 permissions did not change that construction.
The court therefore concluded there was no substantial alteration to the reserved matters application, condition 13 remained to be discharged pursuant to the outline permission, and the approval did not unlawfully ignore condition 13.
Holding and Implications
DISMISSED.
Holding: The appeal is dismissed. The court held that Respondent A lawfully approved the reserved matters application on 4 March 2025. The reserved matters approval was properly construed as an approval pursuant to the original outline permission; condition 13 (drainage) was not a reserved matter governed by the condition 2 timescale and remained subject to its own requirements to be satisfied prior to commencement/occupation.
Implications: The direct effect is that the reserved matters approval stands and no relief is granted to the Appellant. The court did not treat this decision as establishing novel precedent on whether reserved matters submitted under an earlier outline permission may be approved with reference to a later s73 permission; the court preferred to leave that specific question to a case where it is necessary to decide it on the facts.
