High Court (Planning & Environment) — Summary of Judgment

Neutral citation in original opinion: [2025] IEHC 621

Judge: Judge Humphreys (delivering judgment on 13 November 2025)

Factual and Procedural Background

The matter concerned an application for leave to apply for judicial review of a planning decision (identified in materials as ABP-318704-23). The planning permission impugned was a 10-year permission for a nine-turbine windfarm and associated infrastructure, including an access road, on land near a town in County Tipperary. The original planning application was lodged in December 2023; the inspector reported recommending grant with conditions on 26 June 2024; the impugned decision granting permission with conditions was made on 12 September 2024 and the applicant was notified on 16 September 2024.

The Applicant (referred to throughout this summary as "Plaintiff") represented herself. The statutory papers for judicial review were filed on 11 November 2024 (five days outside the usual eight-week planning time limit). The Plaintiff had earlier correspondence with planning authorities and sent various submissions to the board during the application process. The Defendant in the judicial review materials is the planning authority referred to in the documents (referred to here as "Respondent"). A private developer that intervened in the proceedings is referred to in this summary as "Company A" and was joined as a notice party by court order.

Procedurally: after the filing of papers the Plaintiff did not promptly seek a listing date with the List Registrar and engaged in protracted correspondence seeking adjournments and extensions (including repeated emails to registry and requests for adjournment on medical grounds). The court made an initial unless order directing attendance; when the Plaintiff did attend in person it was on the adjourned date. The court heard the leave application on notice on 13 October 2025, reserved judgment, allowed the Plaintiff a concession of a post‑hearing written submission, received opposing submissions and then gave judgment on 13 November 2025.

Legal Issues Presented

1. Whether the Plaintiff has demonstrated substantial grounds to obtain leave to apply for judicial review of the Respondent’s decision to grant planning permission (i.e. whether the pleadings and supporting affidavit, if proved, would establish a substantial ground for the relief sought).
2. Whether the Plaintiff complied with procedural and time requirements for seeking leave in a planning context (including the eight‑week time limit and related rules on seeking extensions).
3. Whether the Plaintiff’s pattern of correspondence, delays and requests for adjournment amounted to a failure to prosecute warranting refusal of leave in the exercise of the court’s discretion.
4. Whether the Plaintiff had standing (sufficient interest) and capacity to bring the application and whether alternative remedies had to be exhausted.

Arguments of the Parties

Plaintiff's Arguments

• The Plaintiff contended that the location of the access road and proximity to her house would cause construction noise, vibration and other impacts; she sought judicial review on grounds including disability and human‑rights related complaints (she is a wheelchair user and cited health concerns).
• The Plaintiff repeatedly sought extensions and adjournments on the basis of medical conditions and related stress; she advanced that those medical circumstances affected her ability to progress the matter within the usual timelines.
• The Plaintiff asserted she had not been afforded adequate access or accommodation in court and sought various procedural accommodations, including additional time to file submissions and access to recordings/transcripts of the hearing.

Respondent's Arguments

• The Respondent and its advisers argued that the Inspector, the County Council and the Board had considered the Plaintiff’s submissions expressly (including reference to the inspector's report at paragraph 10.17.18) and that the Plaintiff’s dissatisfaction was effectively a merits complaint rather than a legal ground for judicial review.
• The Respondent submitted that the papers were filed out of time and no proper extension of time had been sought on affidavit as required by the statutory framework; that the Plaintiff had not shown the evidential basis to meet the statutory test for an extension; and that her lay litigant status did not alter the legal test for extension.
• The Respondent also relied on the procedural rules requiring particularity in pleadings (i.e. the Statement of Grounds was deficient and not properly particularised) and on the Plaintiff’s failure to join the developer as a notice party at the relevant time.

Notice Party (Company A)'s Arguments

• Company A emphasised that the removal of hedgerows complained of in the Plaintiff’s materials pre‑dated the developer’s involvement (alleged activity in 2019) and did not arise from or relate to the grant of permission; therefore the activity complained of could not impugn the lawfulness of the permission now under challenge.
• Company A submitted that the Plaintiff had been made aware of the access road location during the planning process and that the impacts identified by the Plaintiff had been considered. Company A also pointed out that the Plaintiff retains rights against third parties for unauthorised activities if appropriate.
• Company A objected to the lack of particularity in the Statement of Grounds and asserted no adequate factual or legal basis for leave was disclosed.

Precedent	Rule or Principle Cited For	Application by the Court
G. v. DPP [1994] 1 I.R. 374 (Finlay C.J.)	Core legal test for grant of leave to seek judicial review (requirements for standing, substantial grounds and entitlement to relief).	The court applied the G. v. DPP framework (as modified by statute and rules) to assess whether the Plaintiff’s affidavit and pleadings, if proved, would disclose substantial grounds for relief and whether a substantial case in law was made.
Reid v. An Bord Pleanála (No. 5) [2022] IEHC 687	Application of the leave test in planning cases and relevant procedural adjustments.	Referred to as authority for the application of G. v. DPP to planning cases and for procedural considerations in the planning context.
Duffy v. Clare County Council [2023] IEHC 430	Recent High Court application of the leave criteria in planning contexts.	Referred to as part of the body of authorities illustrating how the G. v. DPP test is applied in planning judicial review matters.
Morehart v. Monaghan County Council [2024] IEHC 100	Further recent application of the leave criteria in planning judicial review proceedings.	Referred to as another example of the application of the test for leave in the planning context.
North East Pylon Pressure Campaign Ltd & Ors v. An Bord Pleanála (No.1) [2016] IEHC 300	Discretionary grounds to refuse leave (triviality, lack of good faith and related discretionary considerations).	The court cited this case when explaining that discretionary grounds (such as triviality or lack of good faith) can warrant refusal of leave.
O'Sullivan v. Sea Fisheries Protection Authority [2017] IESC 75	Reasonable latitude afforded to trial courts to give directions and specify timelines; courts should not approach administrative judicial review with criminal‑trial-like formalism.	Cited for the proposition that trial courts have a margin of discretion to control procedure and timeframes and that such latitude is appropriate.
Eco Advocacy v. An Bord Pleanála [2025] IEHC 15	Recent High Court authority on the running of planning lists and the court's procedural directions; reference to codification in O.103 RSC.	Used to support the court's approach to timetable directions and the use of the Rules in controlling the proceedings.

Court's Reasoning and Analysis

The court conducted a structured analysis applying the established criteria for the grant of leave in planning judicial review cases (drawing on G. v. DPP and later authorities) and also considered procedural rules and discretionary grounds for refusing leave. The main strands of reasoning were:

1. Standing: The court accepted that the Plaintiff had sufficient interest (standing) because she had submitted observations during the planning process.
2. Substantial grounds: The court concluded the Plaintiff failed to aver facts in her affidavit and statement of grounds that, even if proved, would support a substantial ground for judicial review. The Statement of Grounds was described as unfocused, argumentative and verified only by a one‑line averment; the complaints principally raised were merits complaints or related to matters outside the Board's decision (for example, historic hedgerow removal in 2019 and third‑party actions), and were therefore not material to the legality of the impugned decision.
3. Consideration of the Inspector's Report: The court noted the inspector expressly addressed the Plaintiff's concerns (citing para. 10.17.18 of the inspector's report) and that the Board was aware of and dealt with those points; thus a complaint that the Board had not considered the submission was unfounded.
4. Procedural compliance and particularity of pleadings: The court held the Statement of Grounds lacked necessary particularity in breach of the Rules of Court. The Plaintiff also failed to join the developer as a notice party within the applicable timeframe and offered no satisfactory explanation for that failure; the pleadings were inadequate to particularise substantial grounds.
5. Time limits: The court observed that the statutory time limit in planning cases (normally eight weeks) was not met and that no proper application for extension of time (by notice of motion grounded in affidavit) was ever made. The court treated the time issue as important but stated it would not rest the decision solely upon it (i.e. the point was obiter).
6. Failure to prosecute and discretionary refusal: The court placed significant weight on the Plaintiff’s protracted failure to prosecute (an 11‑month period in which the Plaintiff did not progress the matter meaningfully, a pattern of non‑attendance and repeated ad hoc requests for adjournment) and concluded that the conduct amounted to a failure to prosecute. The court found that the Plaintiff engaged in an extensive campaign of correspondence yet did not take procedural steps required by the Rules (e.g. filing a motion where directed). That conduct supported a discretionary refusal of leave irrespective of other considerations.
7. Evaluation of medical evidence and adjournment requests: While the court expressed sympathy for the Plaintiff's health issues, it concluded the medical evidence provided was general, often historic, not supported by a doctor's affidavit or oral evidence and did not establish incapacity preventing prosecution of the proceedings. The court also noted that the Plaintiff's volume and vigour of correspondence undermined assertions of total incapacity. The court emphasised that if a party is genuinely unable to pursue proceedings there are procedural mechanisms (e.g. appointment of a guardian ad litem) rather than allowing indefinite delay.
8. Overall conclusion of law and discretion: Taking the foregoing together (insufficiently particularised pleadings that did not disclose substantial grounds, procedural non‑compliance, out‑of‑time filing and a sustained failure to prosecute), the court held the Plaintiff had not satisfied the tests for leave and that discretionary grounds warranted refusal.

Holding and Implications

Holding: The High Court dismissed the Plaintiff’s application for leave to seek judicial review.

The court's order, as recorded in the judgment, was:

• The application for leave to seek judicial review was dismissed, with no order as to costs.
• The court provided directions for any application for leave to appeal to the Court of Appeal (service of written submissions setting out proposed questions of law of exceptional public importance by a specified timetable, provision for a one‑hour oral hearing if requested, and provisions for dealing with any such application on the papers in the absence of a request).
• The court ordered that the Respondent's title be entered correctly in the cause books (substituting the correct corporate title where relevant) and that the order be perfected immediately.

Implications:

• Immediate procedural effect: the Plaintiff’s leave application was refused and the planning decision granting permission remains in force pending any successful appeal or further relief sought in accordance with the directions provided by the court.
• Costs: the dismissal was ordered with no order as to costs (i.e. each side bore its own costs as to the leave proceedings).
• Appeal route: the judgment explains the procedural pathway if the Plaintiff wishes to pursue leave to appeal (application to the High Court under s.50A(7) of the Planning and Development Act 2000 for leave to appeal to the Court of Appeal, or alternatively direct application to the Supreme Court for leave to appeal).
• Broader precedent: the opinion applied established authorities and procedural rules; it did not purport to create novel law. The decision is fact‑specific and its refusal of leave reflects the application of settled tests (insufficiency of pleaded substantial grounds, non‑compliance with rules and discretionary refusal for failure to prosecute) to the facts presented.

Administrative and Ancillary Directions Noted by the Court

• The court noted procedural housekeeping matters: where parties are added they must make appointments with the Central Office to amend cause books; the court also directed correction of a slip‑rule error in the earlier order (amending a mis‑named party to the Plaintiff's correct name), with consent recorded from the Respondent and notice party.
• The court recorded and summarised extensive correspondence between the Plaintiff and court registrars/parties (set out in an Annex to the judgment) and detailed deadlines given and refused for further submissions; the judgment records that judgment would follow promptly after the deadline for any replying submission.
