Anonymized Summary of Judgment

Factual and Procedural Background

The Plaintiffs sought judicial review of a planning decision permitting a solar‑farm project. The substantive High Court judgment dismissed the Plaintiffs' challenge. The Plaintiffs then applied for leave to appeal against that dismissal. The application for leave was supported by written submissions from the Plaintiffs (9 March 2026) and opposed by written submissions from the Respondent (Company A) and the notice party (Company B). A hearing on leave to appeal took place on 12 March 2026. A draft of the present judgment was circulated to the parties on 13 March 2026 for comments; the Plaintiffs failed to respond by the deadline.

Legal Issues Presented

1. Whether a long internal access track (described by the Plaintiffs in detail) to a solar‑farm constitutes a "road" for the purposes of Class 10(dd) of Part II of Schedule 5 of the Planning and Development Regulations, 2001 such that environmental impact assessment (EIA) is required.
2. Whether the application for leave to appeal meets the statutory criteria: (a) the point properly arises; (b) the point is one of law; (c) the point is of public importance and of exceptional public importance; and (d) whether an appeal would be in the public interest.

Arguments of the Parties

Plaintiffs' Arguments

• The internal access track (with specified construction details and dimensions) is effectively a "road" within the meaning of Class 10(dd) and therefore the project required EIA.
• The Court should assess the project "as made" (i.e., as described by the Plaintiffs), and the developer's administrative clarifications should not be allowed to determine the issue.
• A hypothetical argument that the developer could later tarmac the track and thereby create a road without permission (relying on exempted development) supports the need for appellate clarification.

Respondent (Company A) and Notice Party (Company B) Arguments

• The substantive judgment and factual findings show the track is not a road and the developer made clear the tracks would not be tarmac‑finished; accordingly the proposed question does not properly arise.
• The point raised is an application of law to fact, not a pure question of law suitable for appeal.
• An appeal would not be in the public interest because of finality, the public interest in renewable infrastructure, the prejudice to the developer, and the absence of any real uncertainty in the law.
• Delay caused by further appellate proceedings would prejudice the project and public interest in expeditious resolution.

Court's Reasoning and Analysis

The court applied the statutory and jurisprudential criteria for granting leave to appeal. The analysis proceeded in stages:

• Draft judgment procedure: the court circulated a draft and permitted confined comments; the Plaintiffs failed to comply with the deadline.
• Threshold inquiry — Does the proposed question properly arise? The court held it does not: the proposed question contradicted the factual findings of the substantive judgment (particularly that the tracks would not be finished in tarmac) and was premised on counterfactuals and pleadings‑stretching arguments. The Plaintiffs' insistence on assessing the matter "as made" was rejected as illogical because the legality of the permission depends on the project as consented.
• Is the point one of law? The court found the question to be an application of law to particular facts (a mixed question), not a pure point of law suitable for appellate consideration.
• Is the point of public importance or exceptional public importance? The court concluded there was no legal uncertainty warranting appellate resolution. Allowing the Plaintiffs' argument would unrealistically expand the EIA directive to encompass many projects with internal tracks; moreover the Plaintiffs produced no authority from Ireland, other EU states or the CJEU to support their position.
• Is an appeal in the public interest? The court held it was not. Considerations included the public interest in timely delivery of renewable infrastructure, the project's prior approvals at multiple administrative levels, the prejudice to the developer from delay, and lack of any compelling public‑interest countervailing factor. The court noted the acte clair principle meant no referral to the CJEU was required given the absence of real doubt.
• Costs and finality: the court made orders concerning costs if a leapfrog appeal to the Supreme Court is sought and perfected the orders as final in the High Court.

Holding and Implications

Holding: The application for leave to appeal is refused; the application for leave to appeal is hereby DISMISSED.

Consequences and implications:

• The High Court's substantive dismissal of the Plaintiffs' judicial review remains final in the High Court, subject only to any leapfrog application to the Supreme Court.
• If a leapfrog application is made and accepted by the Supreme Court, costs of the leave application are to be costs in that appeal; otherwise, there is no order as to costs of the leave application.
• The decision concludes that, on the facts and authorities before the court, the contention that solar farms are EIA projects by virtue of internal access tracks lacks legal support; the court refused further appellate agitation on this point as not meeting the statutory criteria for leave.
