Judicial Review Summary — High Court (Planning & Environment)

Factual and Procedural Background

The Applicant sought to quash a decision of the Respondent Commission granting planning permission for a large-scale residential development ("the Proposed Development") comprising apartments, commercial and community facilities and associated road works at a site ("the Site") on the edge of The City. Company A (the developer) applied to Company D (the local planning authority) for permission. The Applicant made observations to Company D and to the Commission. Company B (a national roads body) and Company C (a national transport authority) made submissions. Company D refused permission, citing national roads guidelines (Reason 1). Company A appealed to the Commission. The Commission's inspector recommended granting permission; the Commission adopted the recommendation and on the stated materials granted permission (the "Impugned Decision"). The Applicant, unrepresented, sought judicial review to quash the Impugned Decision. Two preliminary grounds (challenging certain guidance documents) were abandoned; two grounds remained: (1) alleged failure to have regard to the Spatial Planning and National Roads Guidelines and/or to give reasons for not following them; (2) alleged inconsistency with the Climate Acts and Climate Action Plans and/or failure to give reasons for not addressing them. Judge Holland delivered judgment dismissing the proceedings and refusing certiorari.

Legal Issues Presented

1. Whether the Commission failed to have regard to, or to give adequate reasons concerning, the Spatial Planning and National Roads Guidelines in relation to the Proposed Development (Ground 1).
2. Whether the Commission acted inconsistently with s.15 of the Climate Acts (as amended) and the Climate Action Plans, or failed to give reasons for any inconsistency, in approving the Proposed Development (Ground 2).

Arguments of the Parties

Applicant's Arguments

• The Commission failed to have regard to §3.7 of the Spatial Planning and National Roads Guidelines regarding "potential negative impacts arising from existing or planned national roads", in particular the interaction of the Proposed Development with the planned national road Project X and associated traffic forecasts.
• The Commission failed to assess cumulative effects on local traffic (including cyclists) arising from the Proposed Development combined with traffic generated by Project X.
• The Impugned Decision is inconsistent with the Climate Acts and Climate Action Plans because the approved road/cycle designs deprioritise active travel and public transport and reduce effective road space for cyclists; the Commission failed to act, so far as practicable, consistently with the Climate Acts.
• The cycle infrastructure design (two-way tracks on one side, shared pedestrian/cycle strips at junctions, toucan crossing) is inadequate in practice and will cause cyclists to avoid segregated facilities, creating unsafe shared carriageway use.

Commission's (Respondent) Arguments

• The Commission did have regard to the relevant guidelines, the inspector's report and the submissions before it; the inspector had addressed the Guideline issue and the Commission adopted the inspector's reasoned conclusions.
• The Commission's recital of matters to which it had regard included the Climate Action Plan; the EIAR, inspector's report and the TTA addressed traffic, active travel and climate considerations.
• Grounds framed as merits-based objections to design choices are not proper bases for certiorari absent illegality (irrationality) and were insufficiently particularised or evidenced.

Company A (Developer) / Expert Evidence

• Company A and its expert deponents explained the design constraints, engagement with the Project X team and Company C, and changes made at the further information stage to align with Project X where practicable while providing active travel and public transport infrastructure.
• Expert Gorman (design engineer for Company A) gave admissible expert evidence that the cycle facilities comply with the applicable design guidance (DMURS, Cycle Design Manual), meet required widths, provide for desire lines and that the proposals do not materially conflict with Project X.
• Company A and its expert contended the Applicant's criticisms were inexpert assertions and, where they raised expert matters, inadmissible for lack of independent expert evidence and cross-examination.

Court's Reasoning and Analysis

Judge Holland applied established judicial review principles emphasising that review assesses legality not merits and that evaluative planning judgements are reviewable on irrationality grounds only, a high threshold. He analysed the Applicant's case through several analytical strands:

• On reasons and regard: the court reviewed the statutory and caselaw requirements for adequate reasons and for a decision-maker to have regard to guidelines. The court stressed reasons must be identifiable with reasonable certainty and may be found in the inspector's report or other materials adopted by the decision-maker.
• On evidential burden and expert evidence: the court applied the principle that the onus of proof rests on the applicant and that technical issues (traffic modelling, road/cycle design) require admissible expert evidence. The Applicant lacked independent expert evidence and was disqualified from giving independent expert opinion as a party; Company A's expert evidence (Expert Gorman) was admissible and uncontradicted.
• On Ground 1 (National Roads Guidelines): the court considered the Spatial Planning and National Roads Guidelines' scope (including §3.7) and held that planned national roads fall within the Guideline's ambit (not limited to EIA-approved projects). However, the court found significant evidence in the planning file (the RRfI, engagement with the local Project Team, the inspector's report and the Commission's adoption of that report) that the Commission had regard to the Guidelines and that Applicant had not rebutted the presumption that the Commission had considered relevant materials. The court treated the challenge as effectively a merits-based disagreement about design choices and concluded there was no admissible evidence of a material failure of regard or irrationality.
• On Ground 2 (Climate Acts / CAPs): the court applied Coolglass and related authorities to analyse s.15 (consistency with climate plans "insofar as practicable"). The court accepted the stringent nature of the obligation but emphasised the practicability qualifier and that many developments will have no discernible impact on climate goals. The court concluded that the differences alleged by the Applicant (directionality and small-scale design choices over c. 300m) would not produce a discernible difference for climate goals on the evidence before the Commission, and the Applicant adduced no admissible expert evidence to the contrary. The court therefore treated Ground 2 as, in substance, a merits-based disagreement within the Commission's evaluative discretion.
• Procedural and discretionary considerations: the court noted the Applicant had not raised some central arguments to the Commission in the form now advanced and emphasised the need to raise points in the administrative process. The court observed that, even if some limited legal defects were arguable, discretionary refusal of relief would be appropriate given the absence of evidential showing of material harm.

Holding and Implications

HOLDING: The judicial review application was dismissed and the Impugned Decision was not quashed. The court refused certiorari and declined to set aside the Commission's grant of permission.

IMPLICATIONS:

• The Commission's grant of planning permission remains effective; Company A may proceed subject to the terms and conditions of the permission (including Condition 7 referencing adherence to DMURS and planning authority requirements).
• The decision does not establish a novel precedent expanding judicial intervention in planning design disputes: the court reaffirmed that evaluative planning judgments about road and cycle design are primarily for expert administrative decision-makers and are only judicially reviewable for illegality (including irrationality) which was not established here.
• The judgment confirms that challenges relying on technical matters (traffic, cyclist behaviour, design) require admissible expert evidence and that applicants who are parties cannot supply independent expert evidence of technical matters without satisfying independence requirements.

Judge Holland ordered further procedural listing for final orders and indicated provisional view that no costs order would be made.
