Hoctor and Ors v An Coimisiun Pleanala and Anor (Approved)

Factual and Procedural Background

The Applicants sought judicial review of the Respondent's decision dated 30 June 2025 to grant planning permission for a windfarm scheme comprising seven turbines, on-site substation, an underground grid connection route to an existing substation, ancillary works, repository areas and related infrastructure. The application to the planning authority was made on 22 September 2023 with supporting EIAR and NIS. The planning authority refused permission on 16 November 2023 for three reasons. The developer (Company A) appealed; the Respondent appointed an inspector who prepared a 309‑page report dated 22 April 2025 recommending permission. The Respondent considered the report and decided to grant permission by order of 30 June 2025 subject to 25 conditions. The Applicants filed their grounds and affidavit on 25 August 2025; leave to apply for judicial review was granted in September 2025. The main hearing occurred on 20 January 2026 and the judgment was delivered by Judge Humphreys on 10 February 2026.

Legal Issues Presented

1. Whether the Respondent's decision to grant permission was invalid for failures to comply with Articles 17–23 of the Planning and Development Regulations 2001 (as amended) and related domestic requirements (alleged invalid application particulars and publicity defects).
2. Whether the Respondent failed to consider or lawfully address interference with property rights and turbary rights (ius tertii and related EIA considerations).
3. Whether the Respondent lawfully permitted structures to overhang or extend across public roads and whether that gave rise to public nuisance or safety defects.
4. Whether waste arising from peat/spoil required a separate licence or rendered the EIA inadequate.
5. Whether Conditions 4 and 5 (implementation of EIAR and NIS mitigation) were ultra vires because they applied to lands not under the developer's control.
6. Whether the Respondent breached s.146(5) and (7) of the Planning and Development Act 2000 by failing to publish the Inspectorate Ecologist's Technical Note within three days and the legal consequences of that omission.
7. Whether Condition 11 (noise limits) was unreasonable or inconsistent with constitutional or EU law.
8. Whether reliance on the 2006 Wind Energy Guidelines without a Strategic Environmental Assessment violated Directive 2001/42/EC.
9. Whether the EIAR/NIS were insufficiently particular (design flexibility of turbines) to permit a lawful EIA/AA under Directive 2011/92/EU (as amended).
10. Whether the Appropriate Assessment (AA) complied with Article 6(3) of the Habitats Directive (reasonable scientific doubt standard).
11. Whether the project was unlawfully "split" (project-splitting) so that the totality of environmental effects were not assessed.

Arguments of the Parties

Applicants' Arguments

• The application and publicity were defective because turbine design was expressed as wide parameter ranges (height, rotor diameter) making the application invalid under Articles 17–23 of the Regulations.
• The Respondent failed to address interference with property and turbary rights and unlawfully relied on s.34(13) to avoid proper consideration; this affected EIA/AA (material assets).
• Turbines 3 and 4 would overhang the public road generating nuisance and safety risks; the Respondent failed to consider submissions on this.
• Peat and spoil management requires a waste licence and further assessment; public participation rights were infringed.
• Conditions 4 and 5 improperly impose mitigation obligations over lands not under developer control and are ultra vires.
• The Respondent failed to publish the Inspectorate Ecologist's Technical Note within the statutory period, depriving the Applicants of information necessary to judge the decision; this warrants relief.
• Condition 11 (noise) is unreasonable and inconsistent with constitutional protections and the EIA Directive.
• Reliance on the 2006 Wind Energy Guidelines breached SEA requirements; the EIAR failed to describe the project sufficiently under Article 5(1) of the EIA Directive; AA was defective; the development was unlawfully project‑split.

Respondent's Arguments

• The Applicants' grounds are numerous, scattergun and inadequately particularised; many complaints are non‑expert assertions unsupported by evidence.
• Design flexibility within defined parameters is permissible and the application included sufficient plans, drawings and notice; public notices complied with the Regulations.
• Claims involving turbary rights are impermissible ius tertii; the planning decision and conditions do not unilaterally extinguish third‑party rights and s.34(13) means permission does not itself confer rights to implement works.
• Overhang and safety issues were considered by the Inspector and planning authority; no evidential basis established to show public nuisance or safety risk.
• Peat/spoil management was assessed in the EIAR (Peat and Spoil Management Plan, Peat Stability Risk Assessment); a waste licence is not required for the proposed on‑site management.
• Conditions 4 and 5 are valid: the Respondent may impose mitigation and monitoring obligations identified in EIAR/NIS; Article 22(2)(g)(ii) and statutory‑undertaker aspects apply to grid works.
• The Respondent concedes a delayed on‑line publication of the Inspectorate Ecologist's Technical Note and accepts declaratory relief only; delay did not affect decision‑making or participation and does not warrant certiorari.
• Noise condition is a lawful planning condition informed by the Inspector's assessment and applicable guidance; EU and constitutional arguments lack evidential support.
• Challenges to the Wind Energy Guidelines require the State/Minister to be joined; the Applicants did not join the correct parties and have not displaced the presumption of validity.
• EIA and AA were carried out; the material before the Respondent was sufficient and no reasonable scientific doubt was shown by admissible evidence.

Company A's (Notice Party's) Arguments

• The application complied with statutory plan and notice requirements; design parameters were limited and properly presented on drawings; swept path and land‑ownership issues were correctly shown within the red line boundary.
• The EIAR and NIS fully addressed peat, spoil, traffic, biodiversity and other impacts; expert affidavits support adequacy of assessments.
• The grid connection works are within the public road corridor and will be carried out as statutory undertaker works; Article 22(2)(g)(ii) applies and landowner letters and landowner maps were submitted.
• Affidavit evidence tendered by the Applicants (Mr Lavelle) is inadmissible or should be given no weight as new evidence and non‑expert; conflicting admissible evidence favours Company A.
• Company A opposes certiorari for the publication breach and supports the Respondent's offer of a declaration only.

Court's Reasoning and Analysis

The Court adopted the established eight‑fold test for granting relief in judicial review and emphasised core principles: judicial review examines legality not merits; evaluative planning judgements attract deference; pleading requirements in judicial review are stringent and EU/technical claims require clear pleaded route‑maps and evidential foundation; the onus of proof lies on the applicant and defects in EIA/AA must be shown by admissible (normally expert) evidence or be patent on the face of the material.

Applying these principles, the Court analysed the Applicants' grounds as follows:

• Core ground 1 (application particulars/publicity): The Court held the Regulations permit limited design flexibility where parameters are defined and that the application contained plans and notices adequate for EIA/AA and public participation. The Applicants had not evidentially established insufficiency; complaints were inadequately pleaded and amounted to non‑expert assertions.
• Core ground 2 (property/turbary rights): The Court treated the turbary complaints as ius tertii; third‑party rights holders were not parties. The Respondent's approach (and condition structure) did not unlawfully extinguish third‑party rights and s.34(13) means permission does not automatically entitle implementation. The Applicants lacked standing to obtain certiorari on that point.
• Core ground 3 (overhang/public road safety): The Court found no evidential basis that the overhang would cause nuisance or danger to the Applicants; the matter was a planning evaluation properly considered by the Inspector and planning authority.
• Core ground 4 (waste/peat): The EIAR included peat/spoil management documentation (Peat and Spoil Management Plan; Peat Stability Risk Assessment). The Court emphasised the Respondent is not required to ensure separate statutory consents (waste licences) will be granted; no evidential showing made that a licence was required or that EIA was inadequate.
• Core ground 5 (Conditions 4 & 5 ultra vires): The Court applied McGowan: conditions cannot be imposed if the applicant cannot reasonably be expected to secure compliance, but the Respondent may impose mitigation/monitoring measures when it is reasonable that the developer can implement them (including via statutory‑undertaker arrangements). Here the grid route fell within the public road corridor and Article 22(2)(g)(ii) and evidence supported the Respondent's approach.
• Core ground 6 (publication delay s.146): The Respondent conceded that the Inspectorate Ecologist's Technical Note was not published within three days due to administrative error; it was published on 19 September 2025. The Court held the breach related to post‑decision publication and did not affect the decision‑making process. The Respondent offered a declaration; the Applicants accepted the declaratory relief at hearing. The Court granted the conceded declaration and treated certiorari as inappropriate on these facts.
• Core ground 7 (noise condition): The Court found no evidential basis to show Condition 11 irrational or unlawful; the condition derived from the Inspector's detailed assessment and applicable guidance. Constitutional arguments did not establish a right to sterilise land use at large distances; actionable nuisance would be a separate remedy.
• Core ground 9 (SEA of guidelines) and related challenges to WEDG 2006 and Draft WEDG 2019: The Court held applicants failed to join the State/Minister (legitimus contradictor) and could not properly collaterally attack national guidelines in these proceedings. The presumption of validity of such guidance was not displaced by the Applicants' pleadings or evidence.
• Core grounds 10–12 (project particulars/EIA adequacy/AA/project‑splitting): The Court repeatedly emphasised the Applicants had not discharged the evidential onus required to demonstrate deficiencies in EIAR/NIS or AA. The grid connection route and Offaly permission were identified and assessed in the EIAR; multiple consents and staged assessments are permissible provided combined effects are considered. No patent flaw was shown.

The Court also assessed procedural conduct and costs: the Respondent offered declaratory relief early and proposed costs allocation limited to the declaratory element; the Applicants did not respond promptly and pursued written submissions on certiorari despite the concession, which the Court found caused unnecessary costs. The Court exercised its discretion to provide costs orders and an enforceable set‑off arrangement as described in the order.

Holding and Implications

HOLDING: The Court granted a declaration that the Respondent did not publish the Inspectorate Ecologist's Technical Note dated 12 March 2025 within the three‑day period required by s.146(5) and (7) of the Planning and Development Act 2000 up to its publication on 19 September 2025. The Court otherwise dismissed the proceedings and refused certiorari of the Respondent's decision.

Implications:

• Direct effect: The Respondent's decision to grant planning permission stands; the Applicants obtain a declaratory remedy limited to the delayed publication breach. The Respondent's concession and the Court's declaration address the statutory publication breach but do not invalidate the planning permission.
• Costs: The Court ordered costs for the declaratory relief to the Applicants against the Respondent up to 14 November 2025. The Respondent's costs incurred in relation to Applicants' continued pursuit of certiorari on Core Ground 6 (15 November 2025 to 20 January 2026) were ordered in favour of the Respondent and enforceable only by set‑off against the Applicants' costs recovery (no net positive balance to Applicants beyond the declared costs). Specific directions for adjudication of costs and a return mention date were ordered.
• Precedential impact: The judgment applies and reiterates existing principles on pleading stringency, evidential onus in EIA/AA challenges, ius tertii limits, workability in statutory interpretation, and discretion in granting certiorari; it does not establish novel legal principles beyond application of those established authorities.
