Unpleaded Questions Cannot Ground Planning Appeal Certification or a Necessary CJEU Reference

1. Introduction

This judgment concerns the restricted right of appeal in Irish planning judicial review proceedings. Following the dismissal of its challenge to permission for a residential development in Terenure, a residents’ company sought certification of three questions concerning material contravention of development plans, strategic environmental assessment and the transposition of EU directives. It also requested a preliminary reference to the Court of Justice of the European Union (“CJEU”).

The High Court refused both routes. Its central conclusion was procedural: the proposed questions did not arise from the case actually pleaded and, in important respects, contradicted it. General questions about planning powers and EU environmental law could not replace the particular legal challenge originally advanced.

The decision principally applies and consolidates existing law rather than announcing a wholly new doctrine. Its significance lies in connecting three requirements: a proposed appeal must arise from the pleaded controversy; its resolution must ordinarily matter to the outcome; and a CJEU reference must be necessary to decide an issue genuinely arising in the proceedings.

2. Background and Procedural History

The applicant was Kimmage Dublin Residents Alliance Company Limited by Guarantee. The respondents were An Coimisiún Pleanála, Ireland and the Attorney General. The developer, 1 Terenure Land Limited, participated as notice party.

The dispute concerned development at Carlisle, Kimmage Road West, Terenure, Dublin 12. The relevant planning history included:

• In Kimmage Dublin Residents Alliance CLG v. An Bord Pleanála & Ors [2024] IEHC 261, Farrell J. quashed an earlier permission for 208 apartments and associated works because the reasons for material contravention concerning excessive building heights were inadequate.
• In Kimmage Dublin Residents Alliance CLG v. An Bord Pleanála, record no. 2023/1028 JR, a separate large-scale residential development permission was quashed by concession and remitted to the planning decision-maker.
• Following remittal, permission was granted on 23 October 2025. The applicant challenged that decision, but Humphreys J. dismissed the proceedings in Kimmage Dublin Residents Alliance Company Limited by Guarantee v. An Coimisiún Pleanála & Ors [2026] IEHC 406.

The present judgment addresses the subsequent application for leave to appeal, not a fresh determination of the development’s planning merits. The narrative records that the substantive judgment was delivered on 26 June 2026 and amended on 8 September 2026 to address jurisprudence affecting an obiter issue. That correction did not affect the certification application.

The applicant proposed questions asking, in substance:

1. What limitations govern the Commission’s power under section 37(2)(a) of the Planning and Development Act 2000 to permit material contravention of a development plan?
2. Does the Strategic Environmental Assessment Directive prevent, or otherwise limit, permission materially contravening a development plan that underwent strategic environmental assessment?
3. Does Article 288 TFEU require legislative amendments following subsequent CJEU interpretations of a directive?

3. Summary of the Decision

The High Court dismissed the application for leave to appeal. Its principal conclusions were:

• The questions did not properly arise. The applicant had moved away from its pleaded case and expressly abandoned its central premise at the substantive hearing.
• Legal character was insufficient. Although the proposed questions were questions of law, that alone did not establish public importance, exceptional public importance or the public interest in an appeal.
• No material legal uncertainty was demonstrated. The court considered the relevant principles governing material contravention, strategic environmental assessment and conforming interpretation sufficiently clear.
• An appeal was not in the public interest. The questions lacked a proper foundation, and further delay would affect a proposed development of 208 social and affordable apartments.
• No CJEU reference was necessary. The questions were outside the pleaded controversy, hypothetical or already answered by clear legal principles.

The court did not need separately to determine exceptional public importance once the preceding requirements had failed.

4. The Statutory Framework: Certification Is an Exceptional Route

Section 50A(7) of the Planning and Development Act 2000 restricts appeals from High Court determinations in planning judicial review proceedings. Certification requires a point of law of exceptional public importance and a conclusion that an appeal is desirable in the public interest. Those requirements are cumulative.

At paragraph 15, Humphreys J. organised the governing principles into five stages:

1. The point must properly arise: it must be grounded in the pleadings, facts, arguments and judgment, rather than formulated as a new controversy after defeat.
2. It must be a point of law: case-specific factual disputes or applications of settled principles will generally be unsuitable.
3. It must possess public importance: the issue must transcend the particular dispute and involve more than disagreement with the result.
4. That importance must be exceptional: ordinary public significance is insufficient.
5. An appeal must serve the public interest: the court must consider practical consequences, including finality, certainty and delay.

The judgment also stresses that the restricted appeal structure does not itself supply the required exceptionality. Nor does adding an EU-law argument or requesting a CJEU reference automatically make a question certifiable.

An important distinction runs through the authorities: the statutory certification test before the High Court is not identical to the Supreme Court’s constitutional permission jurisdiction. Several Supreme Court permission determinations are used analogically, and the judgment expressly describes some as non-precedential. Their practical guidance should not be confused with binding substantive appellate rulings.

5. Analysis: Pleadings Define the Permissible Appeal

5.1 The controlling precedent: Concerned Residents of Treascon and Clondoolusk v. An Bord Pleanála & Ors.

The principal authority was Concerned Residents of Treascon and Clondoolusk v. An Bord Pleanála & Ors. [2024] IESC 28. Murray J.’s explanation of judicial review supplied the judgment’s organising principle: leave permits a party to pursue an identified legal ground; it does not initiate a general investigation into whatever defects might later be discovered.

This principle protects both procedural fairness and the proper judicial function. Respondents must know the legal case they must answer. The trial court must decide that case, rather than an evolving collection of theories. An appellate court should ordinarily review an issue which was properly presented below.

The applicant argued that discussion at the hearing, including the respondents’ explanations of their powers, permitted consideration of its reformulated arguments. Humphreys J. rejected that approach. An opponent’s response does not amend the applicant’s grounds or enlarge the permitted challenge. The court regarded that position as directly supported by Concerned Residents of Treascon and Clondoolusk v. An Bord Pleanála & Ors..

5.2 What the applicant pleaded—and what it later sought to argue

The pleaded environmental challenge rested on the following reasoning:

1. An individual permission materially contravening an SEA-assessed development plan was said to require SEA, or at least SEA screening.
2. Section 37(2)(a) allowed such permissions without imposing that requirement.
3. The legislation therefore inadequately transposed the SEA Directive, and the permission was invalid.

Core ground 3 challenged the Commission’s failure to undertake the asserted assessment. Core ground 4 challenged the State’s transposition of the Directive.

At the substantive hearing, however, the applicant expressly disclaimed the proposition that individual permissions themselves required SEA. It instead pursued an argument that departure from an SEA-assessed plan could be justified only by another appropriately assessed plan or measure. Its proposed appeal questions subsequently ranged more widely over limitations on material contravention and possible prohibitions on granting permission.

The court considered those positions materially different. The original case accepted that section 37(2)(a) authorised material contravention but attacked the absence of an assessment requirement. The later questions sought interpretations restricting or precluding the underlying power itself.

The sub-grounds did contain references to assessed measures and other plans. Nevertheless, the court read the grounds as a whole and treated their essential premise as the alleged need to assess the individual “derogation”. On that reading, those references did not establish the distinct, self-standing case later advanced.

5.3 Supporting authorities on new and abstract questions

Doyle v. An Coimisiún Pleanála [2026] IESCDET 123 was particularly influential. The passages reproduced by Humphreys J. distinguish identifying an error in the High Court’s reasoning from asking an open-ended question detached from the facts and pleadings. An issue may potentially deserve appellate consideration in an appropriate case without arising in the case presently before the court.

GOCE Limited v. An Bord Pleanála [2025] IEHC 43 supported the requirement that the proposed point must have been argued below, rather than invented for the appeal. Leech v. An Bord Pleanála [2025] IESCDET 106 reinforced the related proposition that disputes over the scope of particular pleadings or the interpretation of a particular administrative decision will usually be case-specific.

The practical consequence is significant: a certification application cannot cure the absence of a properly pleaded claim merely by expressing the new argument at a higher level of generality.

6. Analysis: Material Contravention Does Not Mean Unrestricted Power

The applicant characterised the substantive judgment as allowing the Commission an unlimited power to depart from development plans. The court rejected that characterisation.

The distinction was between:

• existing legal constraints, including mandatory statutory provisions, applicable Specific Planning Policy Requirements (“SPPRs”) and the requirement of proper planning and sustainable development; and
• an additional implied threshold, requiring “very significant” or “exceptional” reasons before section 37(2)(a) could be exercised.

The substantive judgment had rejected the latter threshold as unpleaded and unsupported by the legislation’s text, context or purpose. It had not held that the Commission was free from all legal controls.

There was also an independent obstacle to certification: the substantive judgment had considered the applicant’s suggested heightened standard and found that the applicant had not demonstrated that the Commission’s reasons failed it. Consequently, establishing the proposed implied threshold would not, without more, alter the outcome.

Statutory interpretation authorities

The developer’s submissions relied on Heather Hill Management Co. CLG v An Bord Pleanála [2022] IESC 43 and Redwood Extended Care Facility v. Tailte Éireann [2026] IESC 3 to answer the allegation that the court had adopted an exclusively literal interpretation. The substantive reasoning, as described in this judgment, considered text, context and purpose; it simply found no basis for inserting the applicant’s additional restriction.

The applicant invoked Protect East Meath v Meath County Council in support of the hierarchy of planning instruments. The judgment records that argument but does not treat the existence of a planning hierarchy as establishing the proposed limitation. A statutory system may give development plans substantial legal importance while expressly allowing specified departures from them.

The decision therefore should not be read as demoting development plans to optional guidance. Its narrower conclusion is that an additional jurisdictional threshold cannot be inferred merely from the importance of plans, particularly where the argument was not pleaded and would not change the result.

7. Analysis: SEA Applies to Plans and Programmes, Not Individual Project Consents

7.1 The distinction at the heart of the environmental argument

The Strategic Environmental Assessment Directive, Directive 2001/42/EC, concerns environmental assessment of qualifying plans and programmes. Environmental impact assessment operates at the level of individual projects. Although the two regimes are complementary, their scope and functions are different.

Calling an individual planning permission a “derogation” from a development plan does not, by itself, turn that permission into a plan, programme or modification requiring SEA. The court considered the applicant’s contrary pleaded premise incompatible with established EU law.

This conclusion does not mean that individual developments escape environmental scrutiny. It means that an SEA obligation cannot be established merely by pointing to a project’s inconsistency with an SEA-assessed plan. Any applicable project-level assessment obligations remain a separate matter.

7.2 Site de St Teresa's Gardens

The applicant relied on C-09/22, described in the judgment as Site de St Teresa's Gardens, concerning assessment of measures derogating from an existing planning framework.

Humphreys J. held that the applicant had transferred a proposition about plans or programmes derogating from other plans or programmes into the different context of an individual development consent. That step was decisive: jurisprudence requiring assessment of a qualifying framework-setting measure does not establish that each inconsistent project consent must itself undergo SEA.

7.3 Raoul Thybaut and Others v Région wallonne

The court relied expressly on Raoul Thybaut and Others v Région wallonne, C-160/17, ECLI:EU:C:2018:401, paragraph 67. It treated that authority as confirming that an assessed plan may itself provide for individual decisions departing from the plan.

This answered the applicant’s broader suggestion that SEA effectively freezes an assessed development plan against subsequent departures. The court also identified a practical difficulty with that suggestion: a plan would otherwise need to anticipate the detail of every possible future decision.

The limit is important. The decision does not establish that every later measure permitting departures is outside SEA. A later instrument may itself be a qualifying plan or programme. The distinction remains between a framework-setting measure and an individual permission.

7.4 Why McDonald did not resolve this case

The applicant also relied on questions arising in McDonald, particularly whether SPPRs or guidelines permitting departures could require SEA. The respondents distinguished that issue because it concerns potentially normative measures governing future permissions, rather than the individual permission challenged here.

The judgment did not decide the separate questions in McDonald. Their existence did not create uncertainty about the particular project-level argument before the court.

8. Analysis: Transposition, Judicial Interpretation and Legislative Amendment

The third proposed question suggested that the substantive judgment regarded transposition as no more than reproducing a directive’s words. Humphreys J. rejected that description.

8.1 The actual distinction

The reasoning distinguished three situations:

1. A directive is implemented through binding national law. Its obligations must be given legal effect; administrative practice alone is not an equivalent substitute.
2. Later CJEU case law clarifies the directive. Where the national legislation can bear the required meaning, courts apply conforming interpretation.
3. National legislation positively conflicts with the directive as interpreted. Where conforming interpretation is unavailable, legislative intervention is required.

The court expressly accepted the third proposition. It rejected the different proposition that every interpretative CJEU judgment necessarily requires textual amendment of every Member State’s implementing legislation.

8.2 The role of Marleasing

The judgment invoked Marleasing for the obligation of conforming interpretation: domestic legislation must, so far as legally possible, be interpreted consistently with the relevant directive.

That process concerns interpretation of enacted law. It is not the same as attempting to transpose a directive through an administrative practice lacking legislative force. The applicant’s reliance on authorities condemning administrative transposition therefore did not address the court’s reasoning.

8.3 Why the transposition question was hypothetical

No CJEU judgment had been identified imposing the particular substantive restriction on section 37(2)(a) asserted by the applicant. Moreover, the court considered that the section could accommodate a conforming interpretation if a relevant future interpretation arose.

The proposed transposition issue was therefore dependent on the failed SEA argument. Without an established EU obligation omitted from, or contradicted by, domestic law, there was no concrete transposition defect to determine.

Commission v. Netherlands, Case C-339/87, was invoked in the parties’ discussion of inadequate implementation. The State distinguished it because the additional “controls” asserted here had not been shown to exist under the Directive. The judgment’s reasoning follows that distinction: authorities about failure to implement an existing obligation cannot establish the missing obligation itself.

The pleaded grounds also cited Minster for Justice v Workplace Relations Commission, Case 378/17, and Save Cork City v An Bord Pleanála, 2020/563 JR, regarding the effectiveness of EU law and disapplication. Those propositions did not assist without first demonstrating a relevant inconsistency between national law and EU law.

The principal judgment’s finding that the applicant lacked standing to pursue the transposition claim was an additional, case-specific obstacle relied on in the certification debate. It should not be generalised into a rule that environmental organisations can never bring transposition challenges independently of successful certiorari proceedings.

9. Analysis: Why No Preliminary Reference Was Necessary

Article 267 TFEU permits national courts to obtain authoritative CJEU rulings on EU-law questions needed to resolve proceedings before them. The requirement of necessity is not satisfied simply because an applicant can formulate an interesting EU-law question.

The first proposed reference asked whether the SEA Directive precluded national legislation allowing individual permissions materially contravening assessed development plans. The court found that this was substantially broader than the pleaded complaint about failure to assess the individual permission. It was therefore outside the controversy requiring determination.

The second proposed reference concerned a Member State’s obligation where subsequent CJEU interpretation could not be accommodated by conforming interpretation. The court accepted that legislative action would then be required. But that situation had not arisen: no relevant conflicting interpretation had been identified, and no inability to interpret section 37 conformingly had been established.

Thus, the first question lacked a proper procedural foundation; the second addressed an accepted proposition on a hypothetical factual and legal premise. Neither answer was necessary to dispose of the application.

Relevant reference authorities

• Persidera, Case C-112/16, and Van der Weerd, Case C-222/05, were cited in the Commission’s submissions concerning hypothetical questions and the need for a genuine connection to the proceedings.
• Doyle (No.2) [2026] IEHC 207 was invoked for the approach to determining whether a genuine interpretative uncertainty warrants reference.
• Carrownagowan Concern Group v. An Bord Pleanála [2025] IESCDET 8 and [2025] IESCDET 9 illustrated that requesting a reference does not make an otherwise unsuitable appeal question suitable.
• McNamara v An Bord Pleanála [1998] 3 IR 453 and Grace & Anor v An Bord Pleanála [2015] IEHC 870 were cited by the developer concerning possible jurisdictional difficulties in referring questions after final judgment. The court did not need to establish a categorical jurisdictional prohibition: lack of necessity and the clarity of the relevant law disposed of the requests.

The court described the relevant EU-law position as acte clair or acte éclairé. Its conclusion was not merely that the applicant was unlikely to succeed, but that no genuine uncertainty requiring resolution had been demonstrated.

10. Other Certification Authorities and Their Influence

The judgment contains a substantial synthesis of certification jurisprudence. The following authorities support its additional propositions.

Paragraph 16 balances this restrictive account by identifying decisions in which certification was granted. These include R.A. v. Refugee Appeals Tribunal [2015] IEHC 830; B.W. v. Refugee Appeals Tribunal [2015] IEHC 833; K.R.A. v. Minister for Justice and Equality (No. 2) [2016] IEHC 421; S.T.E. v. Minister for Justice and Equality [2016] IEHC 544; R.A. v. Refugee Appeals Tribunal (No. 3) [2016] IEHC 671; and B.S. (India) & Anor. v. Minister for Justice and Equality & Ors. (No. 3) [2020] IEHC 485.

The planning examples were Dublin City Council v. An Bord Pleanála (No. 2) [2021] IEHC 34; Waltham Abbey Residents Association v. An Bord Pleanála [2021] IEHC 597; Sweetman v. An Bord Pleanála (Sweetman XVII) (No. 2) [2021] IEHC 662; Save Roscam Peninsula CLG v. An Bord Pleanála (No. 2) [2022] IEHC 328; Joyce-Kemper v. An Bord Pleanála (No. 5) [2022] IEHC 349; Kerins v. An Bord Pleanála (No. 5) [2023] IEHC 280; Coolglass Wind Farm Ltd v. An Bord Pleanála [2025] IEHC 1; and Heavey v. An Bord Pleanála (No. 2) [2025] IEHC 311.

Those decisions were not analysed individually for substantive propositions. Their collective role was to show that the certification jurisdiction is restrictive, not illusory: a properly grounded application can succeed.

11. Public Interest: Finality, Housing and Demonstrable Consequences

The public-interest requirement independently supported refusal. The court endorsed the developer’s submissions that further litigation would delay 208 proposed social and affordable apartments and that the applicant had not explained a sufficient public benefit from the proposed appeal.

The existence of a separate permission for 145 apartments did not remove that concern. The developer wished to implement the larger social and affordable scheme, not the alternative development. An appeal would therefore delay the particular project under challenge.

The court accepted the sincerity of the applicant’s objections but distinguished that position from the wider public-interest assessment required by the statute.

Authorities governing the public-interest assessment

• Cork Harbour Alliance for a Safe Environment v. An Bord Pleanála [2022] IEHC 231 and Freeney v. An Bord Pleanála [2025] IEHC 36 identify finality, certainty and expedition as legislative objectives.
• Dunnes Stores v. An Bord Pleanála [2015] IEHC 387 makes the project’s nature and the consequences of delay relevant.
• 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 is used analogically both on the limits of case-specific appeals and on the impact of further delay on a developer.
• Glancré Teoranta v an Bord Pleanála [2006] IEHC 250 and Massey v An Bord Pleanála (No.4) [2025] IEHC 309, quoted in the endorsed submissions, reinforce the exceptional nature of appeals and the relevance of expedition.
• Phoenix Rock Enterprises v. An Bord Pleanála & Ors. [2023] IESCDET 97 and McCaffrey v. An Bord Pleanála [2024] IEHC 476, with leave refused in McCaffrey v. An Bord Pleanála [2024] IESCDET 145, support requiring evidence for claims that a judgment is causing wider practical difficulties.
• Colbeam v DLRCC & Jennings [2026] IEHC 613 recognises that judicial notice or another reliable, self-evident basis may sometimes suffice. Mere assertion ordinarily does not.

The housing context did not retrospectively validate an unlawful permission or replace the certification test. It strengthened the public-interest case for finality where the proposed appeal already failed to identify a properly arising, uncertain and outcome-relevant legal question.

12. Draft Judgments: Correction Without Reopening the Case

A separate procedural feature is the detailed treatment of draft judgments under Practice Direction HC 137. The parties were directed to review the draft promptly, communicate any comments, preserve confidentiality and confine their responses to the permitted finalisation process.

Permissible comments included identifying factual or legal errors, ambiguity, omitted reasons, proposed redactions and concerns about new material mentioned in the draft. The process did not permit reargument of the merits.

O'Sullivan v. Health Service Executive [2023] IESC 11 and O'Sullivan v. Sea Fisheries Protection Authority [2017] IESC 75 supported procedural proportionality: fairness does not require elaborate trial-like procedures at every stage.

For confidentiality, the judgment cited Attorney General v. Crosland (No. 2) [2021] UKSC 58, together with 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.

These authorities concern the administration of justice rather than the planning merits. Their practical message is that circulation of a draft is a controlled opportunity to improve the final judgment, not permission to publicise the proposed result or reopen litigation.

13. Complex Concepts Simplified

Material contravention

A significant departure from a development plan. Statutory powers may permit such a departure, but their exercise remains subject to applicable legal requirements.

SEA and EIA

SEA examines qualifying plans and programmes setting a framework for development. EIA concerns qualifying individual projects. A project’s departure from a plan does not automatically make the project subject to SEA.

Screening

An initial assessment of whether full environmental assessment is required. Screening is relevant only where the applicable legal regime requires it.

Transposition

Giving an EU directive effective and binding force in national law. It does not necessarily require copying the directive word for word.

Conforming interpretation

Interpreting national legislation, so far as legally possible, consistently with a directive. It cannot cure a conflict which the domestic text cannot lawfully accommodate.

Acte clair and acte éclairé

Respectively, an EU-law answer sufficiently clear to leave no reasonable doubt, and an issue already clarified by CJEU authority.

Ratio and obiter

The ratio is reasoning necessary to the decision. Obiter observations are not necessary to the result. Here, discussion of an unpleaded argument could not by itself make that argument an outcome-determinative appeal point.

Leapfrog appeal

An application for permission to appeal directly from the High Court to the Supreme Court under the applicable constitutional requirements.

14. Practical Impact and Limits

For applicants: challenges based on domestic statutory interpretation, EU-consistent interpretation, invalid transposition and failures of assessment should be pleaded distinctly. Abandoning one theory at trial does not automatically preserve a different theory for appeal. Certification submissions should identify the precise alleged error and explain how correcting it could change the outcome.

For planning bodies: the decision confirms that section 37(2)(a) is not subject to the additional implied threshold asserted here. It does not remove duties to comply with legislation, apply relevant mandatory requirements or give legally adequate reasons.

For environmental litigation: the judgment reinforces the need to identify the correct assessment regime and the legal character of the challenged measure. It does not exempt genuine plans, programmes or qualifying modifications from SEA merely because they facilitate later permissions.

For EU-law references: proposed questions must connect to an issue the court must decide. Hypothetical future interpretations and general propositions about transposition cannot substitute for demonstrating an existing legal conflict.

The decision’s strongest precedential contribution is therefore procedural discipline. Its substantive observations must be read against the decisive finding that the proposed questions did not properly arise and the alternative conclusion that the asserted restrictions would not assist the applicant on these facts.

15. Order and Conclusion

The High Court dismissed the application for leave to appeal and declined a CJEU reference. It directed immediate perfection of the final orders, including the substantive dismissal and release of the developer from the relevant undertaking or agreement.

If the Supreme Court granted a leapfrog appeal, the costs of the certification application would be costs in that appeal. Otherwise, there was no order as to those costs.

The essential lesson is that appellate importance cannot be manufactured by detaching a legal question from the pleaded dispute. In planning judicial review, a viable appeal must identify a properly arising legal issue, engage with the actual reasons for judgment and demonstrate the statutory public benefit of further litigation. EU-law terminology and a request for a preliminary reference do not dispense with those requirements.
