Telecoms Masts, “Urban Development” and Finality in Planning JR: Leave to Appeal Refused Absent a Pleaded, Truly Doubtful EU-Law Point

1) Introduction

McGowan and Anor v An Coimisiun Pleanala and Ors [No. 2] (Approved) [2026] IEHC 206 is a High Court (Humphreys J.) decision refusing leave to appeal in a planning judicial review concerning permission for a single mobile phone mast. The applicants, Noel McGowan and Karol Warnock, sought to challenge a decision of An Coimisiú́n Pleaná́la (the “commission”), with Vantage Towers Limited and Leitrim County Council as notice parties.

The judgment is “No. 2” because it follows the substantive decision, McGowan v. An Coimisiún Pleanála [2025] IEHC 727, where certiorari was refused. This later judgment addresses whether the applicants met the statutory threshold for a certificate/leave to appeal under the planning JR regime (ss. 50 and 50A of the Planning and Development Act 2000).

The proposed appeal attempted (i) to revive an EU-law “EIA” argument by characterising a telecoms mast as “urban development” under Annex II of the EIA Directive and (ii) to advance a public-health/children point via s.28 guidelines/National Planning Statements. The court refused leave, emphasising: (a) the proposed questions did not properly arise (mischaracterisation and pleading defects), (b) they were not suitable “points of law of exceptional public importance”, and (c) an appeal was not in the public interest given finality, delay and “chilling” effects in planning—particularly for telecoms infrastructure.

2) Summary of the Judgment

  • Leave to appeal refused because the proposed questions either misstated the judgment or did not arise on the pleadings/facts, and in any event were not shown to be points of exceptional public importance or in the public interest.
  • The “urban development” framing was rejected as inapplicable: on any plausible view, a single mast outside a small rural town’s development boundary could not be reclassified as “urban development” without radically and impermissibly expanding the EIA regime.
  • The “near a school/children’s health” angle failed because the school proximity premise was not pleaded in the manner required, and the applicants did not engage with the court’s alternative finding that the “last resort” test had been met.
  • No Art. 267 TFEU reference was required: the point was acte clair/acte éclairé in the sense explained by the CJEU in Consorzio Italian Management and Catania Multiservizi SpA v Rete Ferroviaria Italiana SpA, C- 561/19, and no real doubt was demonstrated by logic or authority.
  • Costs: no order as to the costs of the leave application (subject to a contingent direction if a leapfrog appeal were pursued and accepted).

3) Analysis

3.1 Precedents Cited (and how they shaped the outcome)

A. EIA scope and “listed projects”: resisting category-creep

The court placed the leave application in the shadow of the Supreme Court’s insistence on fidelity to the EIA Directive’s project categories in Concerned Residents of Treascon and Clondoolusk v. An Bord Pleanála [2024] IESC 28. Humphreys J. treated that authority as illustrating a broader rule: EIA obligations attach to projects because they are within listed categories, not because litigants can creatively re-label unlisted projects as falling within a broad heading (e.g., “urban development”).

This logic was reinforced by the judge’s own related decisions, Doyle v. An Coimisiún Pleanála (No. 1) [2025] IEHC 725 and Doyle v. An Coimisiún Pleanála (No. 2) [2026] IEHC 207, which are expressly incorporated by reference. The net effect is a clear High Court line: single telecom masts (not expressly mentioned in the Directive) do not become EIA projects via a vague “urban development” pathway, particularly in rural settings.

B. Finality and avoiding “litigious perpetual motion”

The court’s refusal was underpinned by an institutional concern about endless relitigation through re-packaged “questions” for appeal. The judge invoked Rooney v. Minister for Agriculture and Food [2016] IESC 1 (O’Donnell J.) for the phrase “litigious perpetual motion”, deployed here to characterise leave applications that focus on “debatable rulings” while ignoring the overall lack of traction or materiality.

The emphasis on expedition and finality aligns with planning-specific policy references elsewhere in the judgment, including Cork Harbour Alliance for a Safe Environment v. An Bord Pleanála [2022] IEHC 231, Freeney v. An Bord Pleanála [2025] IEHC 36, and Dunnes Stores v. An Bord Pleanála [2015] IEHC 387, all cited for the proposition that the Oireachtas intends certainty and speed in planning JR and that delay impacts the public interest and the notice party.

C. “Properly arising” questions: pleadings discipline and case-specificity

A core basis for refusal was that the proposed questions did not “properly arise”. This reasoning is anchored in Concerned Residents of Treascon and Clondoolusk v. An Bord Pleanála & Ors. [2024] IESC 28, cited again in the leave criteria section for the rule that the question must fall within pleadings. The court also relied on the Supreme Court’s approach to the limited utility of pleading disputes as appeal points in Leech v. An Bord Pleanála [2025] IESCDET 106.

The applicants’ “school proximity/public health/children” question failed in precisely this way: the court found the argument depended on a factual/legal premise (immediate adjacency to a school) that was not pleaded as a basis for challenge, and was inconsistent with unchallenged findings referenced in the substantive decision.

D. “Point of law” versus application to facts: mixed questions are poor leave vehicles

The judgment draws a sharp line between genuine legal interpretation and fact-bound application, relying on a series of authorities that discourage certificates for mixed questions: B.S. v. Director of Public Prosecutions [2017] IESCDET 134, Halpin v. An Bord Pleanála [2020] IEHC 218, Rushe v. An Bord Pleanála [2020] IEHC 429, Stanley v. An Bord Pleanála [2022] IEHC 671, Eco Advocacy CLG v. An Bord Pleanála, Keegan Land Holdings Limited, An Taisce - The National Trust for Ireland and Client Earth AISBL [2024] IESCDET 62, and Leech v. An Bord Pleanála [2025] IEHC 157.

The “urban development” debate was treated as, at best, an attempt to force an abstract definition onto a concept whose application inevitably depends on context—yet the applicants’ case had no factual pathway to “urban development” because the mast was rural and outside the settlement boundary.

E. Public importance, exceptional public importance, and evidence of real-world difficulty

The decision consolidates a demanding approach to “public importance” and “exceptional” public importance. It cites Patrick McCaffrey & Sons Limited v. An Bord Pleanála [2024] IESCDET 145 and reiterates that points must transcend the case. It also draws on Ógalas v. An Bord Pleanála [2015] IEHC 205 (appeals may resolve doubt), while endorsing the opposite proposition from Nagle View Turbine Aware Group v. An Bord Pleanála (No. 2) [2025] IEHC 3: if the law is not uncertain, an appeal is not warranted.

On claims of uncertainty causing practical difficulties, Humphreys J. aligned with the evidential insistence in Phoenix Rock Enterprises v. An Bord Pleanála & Ors. [2023] IESCDET 97 and the approach in Stapleton v. An Bord Pleanála [2025] IEHC 178: alleged systemic disruption must be evidenced, not asserted.

F. Mischaracterising the judgment and “essay questions”

The court held the first two proposed questions mischaracterised what had been decided (e.g., implying the judge treated “urban development” as discretionary or dispensed with uniform EU interpretation). Authorities supporting refusal where questions distort the decision include Monkstown Road Residents Association v. An Bord Pleanála [2023] IEHC 9, Stapleton v. An Bord Pleanála [2025] IEHC 178, and Cooper v. An Bord Pleanála [2025] IESCDET 96. The warning against asking appellate courts to “write an essay” is drawn from S.A. v. Minister for Justice and Equality (No. 2) [2016] IEHC 646 and repeated via Stapleton v. An Bord Pleanála [2025] IEHC 178.

G. EU law, Art. 267 TFEU, acte clair/acte éclairé, and the requirement of real doubt

The court’s approach to references is structured around the Grand Chamber guidance in Consorzio Italian Management and Catania Multiservizi SpA v Rete Ferroviaria Italiana SpA, C- 561/19. Humphreys J. stated that to show a point is not acte clair, a party must provide either (i) weighty internal logic for the contrary view or (ii) supporting material (case-law or scholarship) capable of changing the result.

The applicants provided neither: the judgment emphasises the absence of any Irish, EU, or member-state authority supporting the “single mast = urban development” theory, and cites Toole v. Minister for Housing (No. 3) [2023] IEHC 378 for the proposition that the reference procedure is not for imaginative hypotheticals but for genuine disputes.

H. Procedural management: draft judgments and confidentiality

While not central to the leave outcome, the judgment contains a firm procedural direction on draft judgments: drafts are not public-domain and must not be published. The court referenced comparative authorities explaining why confidentiality protects the administration of justice, including Attorney General v. Crosland (No. 2) [2021] UKSC 58, Baigent v. Random House Group Ltd [2006] EWHC 1131 (Ch), R. (Counsel General for Wales) v. Secretary of State for Business, Energy and Industrial Strategy [2022] EWCA Civ 181, Public Institution for Social Security v. Banque Pictet & Cie SA and others [2022] EWCA Civ 368, and Itkin v. Wood [2023] JRC 101. This portion functions as a practical micro-precedent for Irish planning JR case management (even if the foreign decisions are persuasive rather than binding).

3.2 Legal Reasoning

A. What the court said (and did not say) about “urban development”

The applicants framed the judgment as permitting a national authority to “exercise a discretion” to decide whether a project falls within Annex II “urban development”, allegedly undermining uniform EU interpretation. Humphreys J. rejected that characterisation:

  • He did not dispense with uniform interpretation; he treated “urban development” as a concept that can be described at legal level but whose application involves evaluative judgment because the category is inherently context-sensitive.
  • He held that, even if one entertained the applicants’ theory, it could not assist on the facts: a single mast in a rural location outside the development boundary is not “urban development” on any plausible interpretation.
  • He warned that accepting such a theory would “transmogrify” numerous rural projects into “urban” projects and would radically extend the Directive beyond what the EU legislature envisaged.

B. “Properly arising” and pleading discipline as gatekeeping

The court treated pleading discipline as not merely procedural formality but as part of the statutory “filter” intended to protect finality in planning:

  • The “school proximity” point failed because the applicants did not challenge the relevant inspector/commission findings and did not plead the premise necessary to trigger the policy consequences they sought to rely on.
  • Even where a topic sounds important in the abstract (public health, children), it cannot be certified if it does not arise on the pleaded case, consistent with Concerned Residents of Treascon and Clondoolusk v. An Bord Pleanála [2024] IESC 28.

C. Public interest balancing: infrastructure, chilling effects, and uncompensatable prejudice

A notable feature is the explicit “systemic” public-interest analysis: Humphreys J. considered telecoms infrastructure as socially important and treated unnecessary legal uncertainty as harmful because it:

  • creates a chilling effect on planning decision-making pending appeal,
  • causes uncompensatable financial prejudice to the developer/notice party through delay, and
  • undermines the Oireachtas policy of finality in planning JR.

The court’s approach is candid: the planning JR regime accepts that some trial-level error may go uncorrected to protect finality; if EU law later shifts, EU error is described as “self-correcting” once contrary authority emerges.

D. The Art. 267 analysis: no demonstrated doubt, no reference

The judge applied the acte clair/acte éclairé framework from Consorzio Italian Management and Catania Multiservizi SpA v Rete Ferroviaria Italiana SpA, C- 561/19 and held:

  • No “weighty internal logic” was shown for the applicants’ reading.
  • No supporting authority or scholarship was produced from the EU “legal space” to show genuine uncertainty.
  • Therefore, no reference was warranted; the procedure is for real disputes, per Toole v. Minister for Housing (No. 3) [2023] IEHC 378.

3.3 Impact

A. Practical impact on EIA challenges to telecoms masts

The immediate impact is to solidify (at least at High Court level, and in tandem with the Doyle decisions) a restrictive approach to attempts to bring standalone telecoms masts into the EIA system by re-labelling them as “urban development”—especially where the site is rural and outside settlement boundaries. Litigants will likely need:

  • a materially different factual context (e.g., as part of a larger listed development), and/or
  • clear EU or member-state authority indicating that the Directive’s Annex II categories must be read to capture such masts.

B. Doctrinal impact on planning leave applications

The judgment also reinforces a stringent “certificate” culture:

  • Mischaracterised questions and abstract definitional projects are unlikely to pass.
  • Pleading discipline is a threshold barrier: policy arguments cannot be bolted on at leave stage if the factual predicate was not pleaded and litigated.
  • Evidence is required to show systemic uncertainty or real-world disruption.

C. EU-law litigation strategy: demonstrating doubt

The judgment sets an exacting expectation for parties invoking EU-law uncertainty:

  • Bring comparative authority (member-state decisions, CJEU materials, or serious academic commentary) if asserting non-acte-clair ambiguity.
  • Do not rely on generic “Commission guidance” references as a substitute for legal authority where the guidance does not materially address the facts.

4) Complex Concepts Simplified

  • EIA Directive (Directive 2011/92/EU): an EU law requiring environmental impact assessment for certain categories of projects. It does not apply universally—coverage depends on whether a project fits within listed categories.
  • Annex II, Class 10(b) “urban development”: a category that can trigger EIA screening for “urban development” projects. The court treated this as a context-sensitive concept, not a catch-all label for any development near a town.
  • Leave to appeal / certificate: in planning JR, appealing is restricted. The applicant must identify a point of law of exceptional public importance and show that an appeal is in the public interest, among other criteria.
  • Pleadings: the formal written statement of what you are challenging and why. If a point is not pleaded, the court will usually not entertain it later—especially at the leave-to-appeal stage.
  • Acte clair / acte éclairé: EU-law doctrines allowing national courts (even apex courts) not to refer a question to the CJEU where the answer is obvious (acte clair) or already effectively settled (acte éclairé). The court here found no real doubt needing referral.
  • Art. 267 TFEU reference: the mechanism by which national courts ask the CJEU to interpret EU law. It is not an “anytime” advisory service; it is for genuine interpretive uncertainty necessary to decide a dispute.
  • Chilling effect: when pending litigation or uncertainty discourages public bodies from making decisions or slows decision-making across the system.

5) Conclusion

McGowan and Anor v An Coimisiun Pleanala and Ors [No. 2] [2026] IEHC 206 is best read as a firm application of planning-JR finality and disciplined appellate gatekeeping, in a context where applicants sought to expand EIA coverage for a single rural telecom mast via “urban development” and to introduce a public-health/school-based policy issue not properly pleaded.

The key takeaways are:

  • EIA arguments must respect the Directive’s listed project structure; “urban development” is not a universal solvent for unlisted projects.
  • Leave-to-appeal questions must accurately reflect the judgment, arise on the pleadings and facts, and be genuinely legal (not merely fact/application disputes).
  • Invoking EU law does not lower the leave threshold; absent real demonstrated doubt (by logic or authority), neither a certificate nor an Art. 267 reference will follow.
  • Public interest in telecoms infrastructure, planning certainty, and protection against delay weighs heavily against speculative appeals that would inject uncertainty without evidential or doctrinal foundation.
