R (Rodmersham Parish Council) v Swale Borough Council [2026] EWHC 2381 (Admin)

The High Court rejected a judicial review challenge to permission for a solar farm at Pitstock Farm, Rodmersham. The judgment addresses publication of planning obligations, the continuing validity of EIA screening, advice to planning committee members and reasonable enquiries about a grid connection.

Tim Smith, sitting as a Deputy High Court Judge in the King’s Bench Division, Planning Court, handed down judgment on 16th September 2026 following a hearing on 9th July 2026. Voltalia UK Limited was the interested party.

The most significant point concerns a draft undertaking published seven minutes before committee. The court considered the opportunity to comment before permission was eventually issued, rather than treating the committee resolution as the end of the decision-making process.

The solar farm and the planning decision

The application covered approximately 65 hectares of agricultural land at Pitstock Farm, Pitstock Road, Rodmersham, Kent. It comprised ground-mounted photovoltaic panels, substations, a control house, inverter and transformer units, storage containers and associated infrastructure.

Pitstock Solar Limited, a company controlled by Voltalia UK Limited, submitted the application. It was validated on 10th January 2024. The committee report reproduced in the judgment records an application area of 64.89 hectares and a proposed generating capacity of 41 MW.

The planning committee resolved to grant permission on 11th September 2025, subject to completion of a planning obligation. Six members supported the recommendation and six opposed it, with two abstentions. The chair’s casting vote secured approval.

Permission followed on 3rd October 2025. Condition 3 limited it to 40 years from the first export of energy, except that the substation and its ancillary infrastructure could remain permanently. Condition 1 required commencement within three years. These conditions should not be confused with a requirement that the entire scheme operate within three years or be removed 40 years after the permission date.

The four grounds of challenge

Rodmersham Parish Council challenged the decision on four grounds, summarised at paragraph 27 of the judgment.

Ground one already had permission to proceed. The other three were considered at a hearing combining their renewed permission applications with substantive argument. All four therefore failed on their merits.

When the undertaking became available

The unilateral undertaking secured a financial contribution towards improvements to identified public rights of way, implementation of a skylark mitigation and compensation strategy, and payment of a monitoring fee. That strategy supplemented planning conditions and addressed replacement breeding habitat.

Paragraph 56 also records two subsequent drafts being uploaded between the first draft and the grant. It does not provide a separate upload date for each. The 22-day interval discussed by the court runs from the first draft to permission, not from publication of the executed document.

Article 40 and an application being finally disposed of

Article 40(3) of the Development Management Procedure Order 2015 requires Part 1 of the planning register to include specified documents for applications not finally disposed of. These include proposed and completed planning obligations.

The parish council argued that seven minutes gave it no practical chance to examine important ecological obligations before the committee debate. It relied on the register’s purpose of enabling informed public participation.

At paragraph 59, the judge rejected the proposition that the conditional committee resolution finally disposed of this application. Permission remained to be granted, and the council could reconsider its resolution before grant. The judgment applied Burkett in explaining that distinction.

On these facts, the relevant opportunity to review the undertaking lasted 22 days. Its terms were comparatively short and understandable, and the parish council could have raised substantive concerns before permission was issued.

Its barrister’s letter of 26th September 2025 criticised the publication process but did not identify deficiencies in the undertaking’s contents. The judge found that criticisms later raised in witness evidence could have been made during that interval.

Article 40(13) contains fuller provisions about final disposal, including appeal periods. The judgment’s decisive point here was the distinction between a conditional resolution and the later grant. It should not be presented as an exhaustive ruling on when every application ceases to belong in Part 1 of the register.

Meaningful publication still requires sufficient time

The judge accepted that seven minutes was insufficient to read and digest the undertaking fully. At paragraph 70, he expressly declined to decide whether seven minutes alone would have satisfied the legal requirement, because that was not the relevant interval here.

Paragraph 69 rejects mere technical compliance through publication at any moment before grant. Sufficient time is fact-sensitive. Relevant factors include the document’s length and complexity, whether specialist knowledge is needed and how quickly a third party can reasonably obtain that assistance.

The court distinguished R (Greenfields (IOW) Limited) v Isle of Wight Council, where no proposed or completed section 106 agreement was published before permission. Rodmersham involved an actual opportunity to comment before grant.

Neither seven minutes nor 22 days therefore supplies a universal rule for other applications. The quality and practicality of the opportunity remain central.

The planning register is distinct from consultation

At paragraphs 63 and 64, the court approved the Greenfields analysis that Article 40 imposes a public register duty, rather than a statutory duty to consult. Publication enables people to understand and comment on the obligation itself.

This does not eliminate any separate requirement for reconsultation, procedural fairness or compliance with a legitimate expectation. The judgment answers the particular Article 40 complaint; it does not establish that councils can always decide applications without consulting on late material.

For applicants, authorities and objectors, the distinction is practical: placing a document on the planning register and deciding whether further consultation is required involve related but separate questions.

Why the earlier EIA screening remained valid

Swale issued a negative EIA screening opinion on 15th November 2023. The parish council argued that subsequent amendments, alleged original omissions and potential cumulative effects required the screening conclusion to be revisited before permission.

The amendments included reduced panel height, relocated panels, an adjusted internal access track, hedgerow screening and further heritage assessment. The parish council also identified potential interactions with the Highsted Park North and South housing applications.

The court emphasised that regulation 3 of the EIA Regulations 2017 applies when permission is granted. An earlier negative opinion cannot simply be treated as a conclusive answer regardless of what subsequently happens.

However, there is no general duty to keep an opinion under constant review, nor an automatic requirement for another full formal screening exercise whenever a proposal changes. The issue is whether relevant changes cast doubt on the earlier conclusion.

Reading the officer report fairly and as a whole, the judge found that the officer had considered the changes, environmental effects and surrounding circumstances. The court rejected an argument based on isolating one passage about limited changes.

The Highsted applications remained undetermined when permission was granted. The judge accepted their treatment in this case as aspirational rather than committed development. That finding should not be extended into a blanket exclusion of pending applications from cumulative assessment.

The judgment applied Swire and Lionbrook in concluding that the officer had asked and answered the right question. Ground two failed. Our EIA Screening and Scoping page explains the wider assessment process.

The chair’s comments about refusal and appeal attendance

Immediately before the vote, the chair referred to the need for substantial reasons for refusal and an expectation that members would attend any appeal to explain those reasons. The parish council argued that this imposed an excessive legal test and improperly influenced members.

The judge considered the whole debate and evidence of mandatory member training. That training covered accurate information, the development plan and material considerations. In context, substantial reasons meant evidence-based reasons that were not trivial or contrived.

The expectation of helping defend an appeal was distinguished from compulsion. Members had not been told that they must carry the council’s defence alone.

No evidence showed that the members supporting approval had been misled. The fact that the vote was close did not establish misdirection. The court granted permission for ground three to proceed but dismissed it substantively.

The decision does not require councillors to adopt officers’ recommendations. It concerns whether these particular remarks unlawfully distorted the committee’s decision, assessed against their context and the available evidence.

Reasonable enquiries about the grid connection

The fourth ground relied on the Tameside duty to make reasonable enquiries. The parish council argued that generation could not begin before 2036, so the council should have investigated the delay before giving weight to renewable energy benefits.

The judgment found that premise incorrect. The available information described 31st October 2036 as a target energisation date, rather than an absolute earliest date. The developer’s undisputed evidence explained that connection dates were subject to review.

The developer had submitted a Gate 2 readiness declaration in August 2025 requesting advancement to 30th October 2028. The court did not treat that request as a confirmed or guaranteed connection date.

The officer report correctly recorded a connection agreement without promising immediate generation or specifying when benefits would start. The judge found that the weight attached to those benefits did not depend on a particular export date.

The three-year commencement condition also did not necessarily require the entire solar farm to be constructed and left idle. Paragraph 150 recognised that lawful commencement could involve comparatively limited works. Whether particular works implement a permission still depends on the permission and applicable legal requirements.

Applying Tameside and Plantagenet Alliance, the court explained that reasonable enquiry does not encompass everything that might be sensible or desirable. Intervention requires a finding that no reasonable authority could regard its available information as sufficient.

That threshold was not met. On these facts, Swale was not required to investigate export dates further, and further enquiries would have added little to what it already knew.

Outcome and practical implications

All four substantive grounds were dismissed and the permission was not quashed. An earlier order treated the proceedings as an Aarhus Convention claim with standard costs limits. Paragraph 159 invited agreement on the consequential order or further submissions; the published judgment does not record a final costs award.

Planning Geek’s practical conclusions are:

• Continue examining important documents after a conditional committee resolution, while permission remains unissued
• Explain substantive defects in a late obligation promptly, alongside any complaint about the publication process
• Assess whether a screening opinion remains valid in light of relevant changes, without assuming a fresh formal exercise is always required
• Distinguish an indicative connection target from a fixed constraint before using it to challenge the planning balance

The principal statutory provisions are Article 40, section 106, EIA regulation 3, section 70 and section 38(6). The related authorities discussed above are those applied in this judgment.
