Planning JR Appeals: No Certificate Where “Design Flexibility” Points Do Not Arise, Are Fact-Application Disguised as Law, and Are Contrary to Finality/Public Interest—Especially for Renewable Energy

1. Introduction

Case: Hoctor and Ors v An Coimisiun Pleanala and Anor [No. 2] [2026] IEHC 174 (Humphreys J., 20 March 2026).
Parties: Sheila Hoctor, Patrick Carney, John Dooley, Michael Mahon, and Regina Hoctor (Applicants) v An Coimisiún Pleanála (Respondent) and Carrig Renewable Energy Limited (Notice Party).
Context: A planning and environment judicial review concerning a renewable energy project. The impugned planning decision dates from 30 June 2025. The High Court had already delivered a principal judgment on 10 February 2026 (Hoctor v. An Coimisiún Pleanála (No. 1) [2026] IEHC 65) dismissing certiorari and granting declaratory relief on “core ground 6”. This second judgment addresses whether the Applicants should receive leave to appeal (a “certificate”) under the restrictive planning JR appeal regime.

Key issue: Whether the Applicants’ proposed questions—framed around alleged unlawfulness of “design flexibility” under the Planning and Development Regulations, 2001 and alleged “de minimis” excusal—satisfied the statutory threshold for leave to appeal: i.e., whether they were points of law of exceptional public importance such that an appeal would be desirable in the public interest.

Secondary (but practically important) procedural issue: The judgment also lays down clear expectations regarding the draft judgment circulation process (what parties may comment on, deadlines, and confidentiality), including an express direction restricting publication of draft judgment contents.

2. Summary of the Judgment

  • The High Court refused leave to appeal and dismissed the application for a certificate.
  • The proposed questions failed the cumulative statutory requirements because they:
    • did not properly arise from the principal judgment and were premised on a misreading of it;
    • were largely fact-specific applications (not true “points of law”);
    • were not of public importance (still less exceptional); and
    • were not in the public interest, particularly given legislative policy of finality and the public interest in timely delivery of renewable energy infrastructure.
  • The Court emphasised that a leave application is not a venue for after-the-event ingenuity: “a trial in the High Court is not a dress rehearsal” (quoting Ambrose v. Shevlin [2015] IESC 10, as most recently quoted in Cave Projects Ltd v. Gilhooley [2025] IESC 3).
  • Orders included dismissal of the leave application; costs treatment depending on any Supreme Court “leapfrog” application; and perfection of orders forthwith.

3. Analysis

3.1 Precedents Cited (and How They Shaped the Decision)

A. “Workable interpretation” and design flexibility

  • Waltham Abbey Residents Association v. An Bord Pleanála [2022] IESC 30, [2022] 2 I.L.R.M. 417:
    The Court anchored its approach in the Supreme Court’s instruction that planning regulations, like law generally, require a workable interpretation. Humphreys J. used this to reject a rigid reading of the Planning and Development Regulations, 2001 that would make reasonable “design flexibility” impermissible in all cases. The judgment treats the Applicants’ proposed appeal as failing to engage with why Waltham Abbey would not govern.
  • Boland v. An Bord Pleanála [1996] 3 I.R. 435:
    The judgment draws an analogy from Supreme Court authority that planning conditions may allow a limited degree of flexibility depending on the nature of the matter—an inherently contextual assessment. This supported the Court’s view that the principal judgment applied established law rather than creating novelty warranting certification.
  • Sweetman v. An Bord Pleanála XVII (No. 1) [2021] IEHC 390 and Sweetman v. An Bord Pleanála XVII (No. 2) [2021] IEHC 662:
    These were relied on (at trial) by the notice party as consistent with “reasonable design flexibility”. Humphreys J. treated the Applicants’ later attempt to weaponise these cases into a “conflict” argument as contrived: the cited jurisprudence and the principal judgment were said to be “totally consistent”.
  • Bailey v. Kilvinane Wind Farm [2016] IECA 92:
    Used to make a key distinction: even if deviations from permission can be “material” in some contexts, that does not entail that a permission that expressly allows flexibility is unlawful. The precedent is treated as non-determinative of the legality of flexibility where structured into the permission/application itself.
  • Krikke v. Barranafaddock Sustainability Electricity Limited [2019] IEHC 825; Court of Appeal [2021] IECA 217; Supreme Court [2022] IESC 41:
    Raised by Applicants to allege conflict, but the Court found no apparent inconsistency, noting the different context and later appellate outcomes.

B. The strict “certificate/leave to appeal” filter in planning JR

This judgment is primarily a synthesis and application of established “certificate” principles, heavily supported by a dense line of authority.

  • Concerned Residents of Treascon and Clondoolusk v. An Bord Pleanála & Ors. [2024] IESC 28:
    Cited for the proposition that a certified question must fall within the pleadings. The judgment uses this to reinforce that certification cannot be obtained by reformulating the case post-trial.
  • Leech v. An Bord Pleanála [2025] IESCDET 106:
    Extensively quoted for the point that pleading issues and alleged misinterpretation of a specific administrative decision are usually case specific and do not generally raise issues of law of public importance. This aligns closely with Humphreys J.’s conclusion that the Applicants’ questions were fact-application and misreading.
  • GOCE Limited v. An Bord Pleanála [2025] IEHC 43:
    Supports the principle that questions for appeal must have been argued at trial and not newly minted for appeal.
  • S.A. v. Minister for Justice and Equality (No. 2) [2016] IEHC 646 and Morehart v. An Bord Pleanála [2025] IEHC 701:
    Cited on the “determinative” character of a point: certification should not be granted for issues that would not change the outcome or that merely generate additional litigation without practical consequence.
  • Rooney v. Minister for Agriculture and Food [2016] IESC 1:
    Used to emphasise litigation discipline: focusing on a “debatable ruling” rather than the overall merits can lead to unproductive procedural motion.
  • Monkstown Road Residents Association v. An Bord Pleanála [2023] IEHC 9 and Stapleton v. An Bord Pleanála [2025] IEHC 178:
    Used to police the framing of proposed questions: they must accurately reflect the judgment; must be specific; and must not be exaggerated into appealable “issues”.
  • Cooper v. An Bord Pleanála [2025] IESCDET 96:
    Supports the proposition that a party’s misunderstanding does not create general public importance.
  • Halpin v. An Bord Pleanála [2020] IEHC 218; Rushe v. An Bord Pleanála [2020] IEHC 429; Stanley v. An Bord Pleanála [2022] IEHC 671; and 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:
    Collectively used for a central boundary: proposed questions that are really about the application of settled law to facts are generally unsuitable for certification as “points of law”.
  • Ógalas v. An Bord Pleanála [2015] IEHC 205 and Nagle View Turbine Aware Group v. An Bord Pleanála (No. 2) [2025] IEHC 3:
    Used to draw a critical distinction: certification may resolve genuine doubt, but where the law is not uncertain, it is not in the public interest to appeal.
  • Callaghan v. An Bord Pleanála [2015] IEHC 493 and Maguire T/A Frank Pratt & Sons (No. 2) [2023] IEHC 209:
    Used to reject “novelty-by-assertion”: mere disagreement or claimed novelty does not demonstrate uncertainty or public importance.
  • Carrownagowan Concern Group v. An Bord Pleanála [2025] IESCDET 8 and Carrownagowan Concern Group v. An Bord Pleanála [2025] IESCDET 9:
    Cited to make clear that adding a request for a CJEU reference does not “upgrade” an otherwise uncertifiable point.

C. Public interest, finality, and renewable energy/infrastructure

  • Cork Harbour Alliance for a Safe Environment v. An Bord Pleanála [2022] IEHC 231 and Freeney v. An Bord Pleanála [2025] IEHC 36:
    Used to situate the certificate test within the Oireachtas policy of finality, certainty, and expedition in planning judicial review.
  • Dunnes Stores v. An Bord Pleanála [2015] IEHC 387:
    Cited for the legislative objective to prevent major projects being “unnecessarily delayed”, supporting the Court’s view that further appeal here was not desirable.
  • Phoenix Rock Enterprises v. An Bord Pleanála & Ors. [2023] IESCDET 97:
    Used to reinforce that claims of practical uncertainty require evidence; the Supreme Court’s Article 34 function is not advisory.
  • Carrownagowan Concern Group v An Bord Pleanála [2024] IEHC 549:
    Relied on (in submissions endorsed by the Court) for the proposition that renewable energy projects may be treated in EU law as being in the overriding public interest in certain circumstances, and for the broader theme that delay to permitted renewable energy infrastructure cuts against the public interest in further appeals.
  • Hellfire Massy Residents Association v. An Bord Pleanála [2022] IESC 38:
    Invoked via quotation from Condon (No.2) (below) to emphasise that appeals which “spread maximum confusion” are not in the public interest.
  • Condon (No.2) [2026] IEHC 136:
    Used as an analogy for refusing certification where an appeal is premised on misunderstanding and where the Supreme Court has already clarified the relevant “workable interpretation” approach.

D. Litigation discipline and the non-public status of draft judgments

  • Ambrose v. Shevlin [2015] IESC 10 (as quoted in Cave Projects Ltd v. Gilhooley [2025] IESC 3):
    Central rhetorical and procedural anchor: High Court trial is not a rehearsal for later perfected arguments.
  • O'Sullivan v. Health Service Executive [2023] IESC 11 and O'Sullivan v. Sea Fisheries Protection Authority [2017] IESC 75:
    Used to justify a disciplined approach to procedure and to reject the notion of an “entitlement to elaborate procedures at every point”.
  • Attorney General v. Crosland (No. 2) [2021] UKSC 58 and related UK/Jersey authorities:
    Cited to support the Court’s direction that draft judgments are not public domain and should not be published or transmitted except for the limited purpose of assisting finalisation. While not substantive to the certificate refusal, this portion of the judgment is significant for day-to-day litigation conduct.

3.2 Legal Reasoning

A. The Court’s “sequenced gatekeeping” approach

Humphreys J. treated the certificate test as requiring satisfaction of multiple cumulative conditions, then examined the Applicants’ questions through that structure:

  1. Do the points properly arise?
    The Court answered “no”: the questions were “reconfigured after the event” and premised on an incorrect assumption of non-compliance with the regulations. A decisive feature was the Court’s view that the Applicants’ formulation depended on a false premise that the principal judgment had treated a “breach” as de minimis; the judge clarified that any discretion comments were “obiter”, “fall-back”, and “counterfactual”, and not a de minimis excusal of illegality.
  2. Are they points of law?
    The first and third questions were characterised as fact-application. The second could be “squinted at” as a legal question, but was disconnected from the actual findings because the premise (non-compliance) had not been established.
  3. Are they of public importance (and exceptional)?
    The Court held that whether design flexibility creates a planning issue is inherently case-by-case and evidence-dependent and therefore not susceptible to a general, certifiable answer. The claimed jurisprudential “conflict” was labelled contrived.
  4. Is an appeal desirable in the public interest?
    The Court held “no”, placing weight on: (i) finality policy in planning JR; (ii) the project’s renewable energy character and delay impacts; and (iii) non-compensatable financial prejudice to the developer.

B. Substantive planning point kept in its proper place: “reasonable design flexibility”

Although this is a certificate decision, it contains an important clarification of what the principal judgment was taken to have held:

  • The Planning and Development Regulations, 2001 do not prohibit reasonable design flexibility where it does not create a planning issue.
  • The Applicants’ attempt to convert the case into a binary “flexibility permitted vs prohibited” dispute was rejected as failing to engage with the “workable interpretation” mandate from Waltham Abbey Residents Association v. An Bord Pleanála [2022] IESC 30.
  • The judgment also notes (as a practical answer to “future importance”) that design flexibility is now “expressly addressed” by the Planning and Development Act 2000 as amended (sections 32H to 32L, commenced 19 December 2023), undermining the claimed forward-looking significance of an appeal on older regulatory wording.

C. Onus and evidence: the Court rejects a “reverse burden” reframing

A recurring theme is that Applicants tried to shift the burden: arguing that once they point to supposed regulatory non-compliance, it becomes for others to prove no planning issue arises. The Court treated that as “begging the question”: if the law permits flexibility and the decision falls within it, there is no breach requiring “excusal”. The failure to prove unreasonableness at trial was fatal, and the leave application could not resurrect that evidential deficit.

3.3 Impact

  • Reinforced discipline in planning appeals: The decision is a strong statement that certificate applications cannot be used to (i) repackage factual disputes, (ii) introduce new authorities and arguments that were not central at trial, or (iii) manufacture “conflicts” to satisfy the public-importance threshold.
  • Design flexibility litigation framed as evidence-driven: Future challengers to “design flexibility” must expect that courts will treat the question as context- and evidence-dependent (does it create a planning issue?), making it hard to elevate to a general appeal point.
  • Public interest and renewable energy: The judgment explicitly integrates the climate/renewables dimension into the public-interest limb of the certificate test, making delay a concrete factor weighing against appeals in appropriate cases.
  • Draft judgment confidentiality and comment discipline: The detailed guidance (and direction) on draft judgments signals firmer judicial management: comments are confined to error-spotting and practical matters, not reargument; and dissemination of draft outcomes is prohibited outside the limited purpose of assisting finalisation.
  • Reduced “future relevance” where legislation has moved on: By noting that design flexibility is now addressed in the Planning and Development Act 2000 as amended (sections 32H to 32L), the judgment provides a template argument against certification where the alleged point is overtaken by legislative change.

4. Complex Concepts Simplified

  • “Leave to appeal” / “certificate” (planning JR): A special permission gateway. Unlike ordinary appeals, in planning judicial review an appeal is generally barred unless the High Court certifies that the appeal involves a point of law of exceptional public importance and that an appeal is desirable in the public interest.
  • “Point properly arises”: The proposed appeal question must emerge from the case as pleaded, argued, and decided—not a new theory built after losing at trial.
  • “Point of law” vs “application of law to facts”: Courts distinguish between (i) interpreting what the law means (law), and (ii) deciding whether particular facts satisfy an already-understood test (fact-application). Certificate appeals target the former.
  • “Public importance” and “exceptional public importance”: The issue must matter beyond the parties and case facts, and the importance must be unusually high given the statutory policy that High Court planning JR decisions should usually be final.
  • “Obiter”, “fall-back”, “counterfactual”: Comments not essential to the decision (obiter), offered as an alternative reasoning route (fall-back), sometimes on a “even if I am wrong” basis (counterfactual). Such remarks are less apt as foundations for appeal questions.
  • “De minimis”: A doctrine sometimes used to ignore trivial breaches. The judge’s key point here was that he did not treat anything as an excused “breach”; rather, he found the Applicants had not established non-compliance in the first place.
  • “Workable interpretation”: A principle that legal rules should be interpreted so they can operate in real administrative settings, avoiding readings that create impractical or unworkable outcomes.
  • Draft judgment circulation: A pre-publication draft sent to parties to identify errors and practical issues. It is not an invitation to reargue and is not public; the judgment contains an express direction restricting publication.

5. Conclusion

Hoctor (No. 2) is a robust restatement of the restrictive planning JR appeal architecture: certification will be refused where proposed questions misread the principal judgment, do not arise from what was actually decided, collapse into fact-specific application, or attempt post-trial reconstruction. The judgment also underscores that “design flexibility” disputes are ordinarily evidence-driven and project-specific, limiting their capacity to meet the “exceptional public importance” threshold. Finally, it embeds the public interest in renewable energy delivery and procedural finality as real, weighty factors against further delay, while also setting clear expectations around confidentiality and discipline in the draft-judgment process.
