Anonymised Summary of Judgment by Judge Humphreys

Factual and Procedural Background

This judgment concerns a planning permission granted on 30 January 2024 by the national planning appeals body (the Commission (Company C)) allowing the construction of a single-storey discount food store with ancillary works on mixed-use-zoned lands in a regeneration area north of a city (the Site). Company E was the developer / notice party who applied for permission. Company A and Company B (the Applicants), who operate a nearby existing district shopping centre (Company A), challenged the Commission's grant of permission by judicial review commenced in March 2024. The planning authority at first instance (the planning authority (Company F)) had granted permission in September 2022. The Commission conducted a de novo appeal process, including an inspector's report dated 19 December 2023 and a decision of 30 January 2024.

The Applicants sought relief by way of certiorari quashing the Commission's decision and advanced multiple grounds. The key pleaded grounds alleged: (1) the proposed development materially contravened Objective LCC06 of the relevant development plan and that the Commission failed to apply the Retail Planning Guidelines properly; (2) the planning application was invalid because it lacked landowner consent under Article 22(2)(g) of the Planning and Development Regulations 2001; (3) the planning authority failed to notify statutory consultees under Article 28(1)(n); and (4–7) various alleged failures in relation to EIA screening and the transposition/validity of Article 109(2) of the Regulations and related EU law issues.

The matter was heard on 10–11 July 2025. Judge Humphreys delivered a written judgment on 3 October 2025. The court concluded that the Applicants' challenge to the validity of the application based on third-party land rights failed, that the failure to notify statutory consultees did not warrant certiorari because the Commission used its s.131 powers to rectify the omission, and that the Commission had failed to engage with the specific development plan objective LCC06 as required by settled law. For that reason the court quashed the Commission's decision by certiorari. EU law grounds were not decided as they were unnecessary to the result.

Legal Issues Presented

1. Whether the Commission's grant of planning permission materially contravened Objective LCC06 of the development plan and, if so, whether the Commission lawfully addressed any such contravention in accordance with the requirements identified in Sherwin v. An Bord Pleanála.
2. Whether the planning application was invalid for lack of landowner consent under Article 22(2)(g) of the Planning and Development Regulations 2001 and whether third parties (the Applicants) could challenge that alleged defect (the jus tertii issue).
3. Whether the planning authority's (Company F's) failure to notify statutory consultees under Article 28(1)(n) of the Regulations was a fatal defect not cured by the Commission's use of its powers under s.131 of the Planning and Development Act 2000.
4. Whether the Commission erred in law in its screening for Environmental Impact Assessment (EIA), including whether Article 109(2) of the Regulations validly transposed the EIA Directive and whether adequate reasons and objective information supported the conclusion that EIA was not required.

Arguments of the Parties

Applicants (Company A and Company B)

• Primary substantive complaint: the proposed development materially contravened Objective LCC06 (the development plan's preference for locating new retail within existing town/district/village centres where practicable and viable), and the Commission failed to interpret and apply LCC06 or to provide adequate reasons.
• The Retail Impact Assessment (RIA) prepared by the developer (Company E) was deficient and did not demonstrate that the district centre could not practically or viably accommodate the proposed store; the Applicants had identified a suitable 14,000 sq ft option within their centre which Company E never explored.
• The planning application was invalid at lodgment because it lacked the consent of the landowner (Company F) for part of the red-line area; subsequent provision of consent could not validate an otherwise invalid application.
• The planning authority failed to notify statutory consultees (Heritage Council and An Taisce) under Article 28(1)(n) despite the submission of a Natura Impact Statement, and the Commission could not cure that omission simply by using s.131.
• Additional grounds alleging errors in EIA screening and the validity of Article 109(2) of the Regulations and related transposition matters under domestic and EU law.

Commission (Company C)

• Preliminary plea that the Applicants' challenge to landowner consent raises a jus tertii objection and is not permissible because the Applicants are not the landowner.
• The planning application and the decision were valid: the planning authority had effectively validated the application at first instance and the developer submitted the required landowner consent at the RFI stage; any alleged technical defect did not render the application void.
• As to consultation, the Commission exercised its discretion under s.131 to notify statutory consultees and to request observations, thereby ensuring that the substantive aims of Article 28(1)(n) were met; any procedural defect was technical and not a basis for certiorari.
• The Commission denied any material legal error in relation to the retail policy assessment and said it properly had regard to the Retail Planning Guidelines and the development plan in the course of its de novo assessment.

Notice Party / Developer (Company E)

• The RIA complied with the Retail Planning Guidelines and the sequential test; there was no suitable, available and viable unit of the order alleged within the district centre.
• There was no legal obligation on the developer to approach the Applicants to test availability; the inspector's site inspection and the evidence before the Commission supported the conclusion that the district centre could not accommodate the proposed store.
• Any alleged defect in landowner consent (if it existed) was cured during the planning process and, in any event, the Applicants lacked standing to advance a jus tertii challenge.
• The Commission and inspector took appropriate account of planning policy and the sequential approach; their evaluative judgment was within lawful discretion and not subject to substitution by the court.

State Respondents (Company D)

The record indicates the State respondents filed a statement of opposition but did not pursue modularisation; the State's submissions did not substantially advance separate substantive arguments on the principal issues (the record frequently records "N/A" for the State on particular points).

Court's Reasoning and Analysis

The court structured its reasoning by addressing first the procedural/domestic-law grounds (core grounds 2 and 3) and then the principal substantive ground (core ground 1, material contravention). The principal legal framework governing plan contraventions was set out from section 37(2) of the 2000 Act and developed through the Supreme Court authority Sherwin, which the court treated as dispositive on how inspectors and the Commission must approach any asserted contravention of specific development plan provisions.

Key analytical steps and findings:

1. Jus tertii / landowner-consent challenge (core ground 2): the court accepted that an allegation about compliance with Article 22(2)(g) concerning landowner consent was, in substance, a jus tertii complaint. Established authorities (including Frascati and Mohan) preclude third parties from advancing complaints based solely on another party's property rights. On the facts there was no realistic basis for certiorari: the planning authority had accepted or validated the application and any alleged defect was not a proper basis for quashing the permission raised by persons who were not the landowner. Accordingly core ground 2 failed.
2. Failure to notify statutory consultees (core ground 3): the court acknowledged that an NIS had been submitted, which should ordinarily have triggered Article 28(1)(n) notifications by the planning authority. The planning authority (Company F) had not sent those notices, but the Commission (Company C) subsequently used its section 131 discretionary powers to notify the relevant consultees during the appeal. The court treated this as an appropriate substantive remedy in the circumstances and held that certiorari was not warranted for this omission: the Applicants had an opportunity to participate in substance and no material prejudice was shown. The court relied on authorities against quashing decisions for purely technical procedural errors where substance has been addressed (e.g. Moore; Save Cork).
3. Material contravention of Objective LCC06 (core ground 1): applying Sherwin, the court emphasised the necessity for a decision-maker to focus expressly on the specific plan provision alleged to be contravened. The court found that Objective LCC06 is a clear objective expressing a preference that new retail be located within existing centres where practicable and viable. Given the proximity of the proposal to the existing district centre operated by the Applicants, the materials before the inspector and Commission required focused consideration of whether the district centre could accommodate the proposal and whether locating there would be practicable and viable.
4. The inspector's report and the Commission's decision did not engage with LCC06: the inspector's analysis of the district centre's ability to accommodate the proposal was limited to a snapshot observation of occupancy and activity and did not interpret or apply LCC06's practicability/viability test or engage with the Applicants' evidence that a suitable unit (of about 14,000 sq ft as described in Applicants' submissions) could be provided if cooperation with the centre owner were undertaken. The inspector went so far as to assert the plan "nowhere" required the convenience retail to be at the district centre — a formulation the court regarded as inconsistent with the substance of LCC06.
5. The court held that the Commission's failure to identify and apply LCC06 amounted to a legal error because Sherwin requires explicit engagement with the text of the relevant plan provision and an express application of that test. It was not enough that other parts of the plan or the sequential test were considered: the specific objective had to be addressed. The absence of such engagement meant the decision-making process was legally flawed.
6. Evidence and "harmless error": the court reviewed the developer's affidavits that sought to show the error was harmless (i.e. that no viable accommodation in the district centre existed and that the developer had no obligation to approach the centre owner). The court noted the general principle that judicial review is to be assessed by reference to the material before the decision-maker and that post-decision affidavit evidence is ordinarily inadmissible except in defined circumstances (e.g. to show harmless error). Where an error is demonstrated, the onus shifts to the opposing parties to show harmlessness, and in the absence of cross-examination such evidence is problematic. The court concluded that the developer's evidence did not discharge the onus to show harmlessness, and in any event did not address the core legal defect: lack of engagement with LCC06.
7. EU law / EIA issues: because the court concluded the domestic-law defect required quashing the decision, the court did not decide the EU law grounds (core grounds 4–7) and observed that those issues might have required referral to the CJEU if they had been necessary to determine.

Holding and Implications

Holding:

The court granted relief by way of certiorari and quashed the Commission's decision of 30 January 2024 to grant planning permission for the proposed development. This is expressed in the order made by the court which directed an order of certiorari in terms of the primary relief sought by the Applicants.

DISPOSITION: The court allowed the Applicants' substantive challenge in part by quashing the impugned decision for the reasons set out (failure to engage with Objective LCC06), dismissed the Applicants' separate challenges based on landowner-consent and statutory‑consultation technicalities, and did not decide the EU law/EIA grounds as they were unnecessary to the result.

Immediate Consequences for the Parties

• The Commission's grant of planning permission in the impugned decision is quashed and of no effect following perfection of the court's order.
• Core grounds 2 (landowner-consent/jus tertii) and 3 (notification of statutory consultees) were dismissed; the court found no basis for certiorari on those grounds.
• EU law and EIA-related claims (core grounds 4–7) were not decided; the court noted those issues could have required further proceedings or references but held them unnecessary to the outcome.
• The court made an order for costs in favour of the Applicants against the first named respondent (the Commission (Company C)), limited to costs that would have been incurred had the Applicants confined proceedings to the issue on which they succeeded; no order as to costs in favour of or against other parties unless otherwise applied for before the mention date set by the court.

Wider Implications

The judgment applies and elucidates established principles (in particular from Sherwin) about the required engagement with specific development plan provisions when material contravention is alleged. The court emphasised that decision-makers must identify, interpret, and apply the precise text of the plan provision in their reasoning rather than subsuming it into other planning considerations. The court did not purport to create new law beyond the application of those principles to the facts before it. The EU law and EIA issues were left undecided.

Order and Procedure

The court ordered:

1. An order of certiorari quashing the Commission's decision (relief 1).
2. No order on any claim not decided, without prejudice to future proceedings.
3. Costs to the Applicants against the Commission limited to the costs related to the issue on which they prevailed, subject to adjudication if the parties cannot agree.
4. Further procedural directions concerning filing of written submissions for public release and a mention date to confirm the order (the matter was listed to confirm the order on 13 October 2025).
