Coumnagappul Wind Farm Ltd v An Coimisiun Pleanala (Approved)
Smart Summary
Factual and Procedural Background
This was an application under section 50(8) of the Planning and Development Act 2000, as amended, seeking to extend time to apply for judicial review of a decision of The Commission made on 11 April 2025. [Para 13] The Applicant, a company seeking permission to build a 10-turbine wind farm and associated infrastructure in County Waterford, received the refusal decision on 16 April 2025, but its solicitor misread the decision date as 27 April 2025 and the eight-week deadline therefore was not met. [Para 15][Para 17][Para 27][Para 29][Para 34] The error was discovered on 11 June 2025, the leave application was brought on 13 June 2025, and the court noted that the application was eight days late. [Para 35][Para 36][Para 38]
Legal Issues Presented
- Whether mistaken legal advice or a misreading of the decision date constituted “good and sufficient reason” to extend time under section 50(8). [Para 17][Para 24]
- Whether the circumstances causing the delay were outside the Applicant’s control, as required by section 50(8)(b). [Para 22][Para 24]
- Whether, applying the interests of justice and the strict planning time limits, the court should grant an extension despite the delay. [Para 59][Para 78][Para 117]
Arguments of the Parties
Applicant's Arguments
- The Applicant said mistaken legal advice as to the relevant time limit can amount to good and sufficient reason, relying on F.G. v The Child and Family Agency and G v The Child and Family Agency. [Para 55]
- It argued that the court should take a holistic view of all relevant circumstances, including public-interest factors, relying on Heaney v. An Bord Pleanála and Thomson & anor v An Bord Pleanála. [Para 59]
- It submitted that the cases relied on by The Commission concerned mere ignorance of the law and were distinguishable. [Para 57]
The Commission's Arguments
- The Commission argued that an applicant is generally bound by the acts and omissions of legal advisers, so a solicitor’s mistake in calculating time is ordinarily attributable to the applicant. [Para 60]
- It submitted that ignorance or misunderstanding of the limitation period does not justify an extension, and that the mistake here was an internal matter within the Applicant’s own responsibility. [Para 61]
- It further argued that accepting such an error would undermine certainty, finality, and the effectiveness of the strict time limits in section 50. [Para 62]

Application by the Court |
| F.G. v The Child and Family Agency |
Relied on by the Applicant for the proposition that incorrect legal advice may support an extension of time. [Para 55] |
The court distinguished it on the basis that the facts there were materially different, including the applicant’s litigant-in-person status and the broader interests-of-justice context. [Para 66][Para 71][Para 72] |
| G v The Child and Family Agency |
Supreme Court authority said to show that mistaken legal advice can satisfy the section 50(8) test. [Para 55] |
The court held that the case did not displace the general rule that a client is bound by the acts of legal advisers, and that its facts were not comparable to the present case. [Para 65][Para 72][Para 74] |
| Heaney v. An Bord Pleanála |
Cited for a holistic assessment of all relevant circumstances when deciding whether to extend time. [Para 59] |
The court accepted that the overall context matters, but found the Applicant’s explanation insufficient when assessed against the strict statutory purpose and the missing evidential detail. [Para 59][Para 117][Para 120] |
| Thomson & anor v An Bord Pleanála |
Cited for the proposition that “good and sufficient reason” must be assessed in a broader discretionary, interests-of-justice framework. [Para 59] |
The court used it to confirm that the analysis is not mechanistic, but still concluded that the delay here was not adequately explained and should not be excused. [Para 59][Para 77][Para 120] |
| Casey v An Bord Pleanála |
Relied on for the principle that delay caused by a legal agent is attributable to the applicant. [Para 60][Para 95] |
The court treated this as closely aligned with the present facts and relied on it to hold that the solicitor’s error was legally attributable to Company A. [Para 95][Para 96][Para 103][Para 104] |
| G.K. v International Protection Appeals Tribunal |
Cited for the proposition that a represented applicant is bound by counsel’s or advisers’ acts and omissions, and that granting relief on such a basis would weaken statutory time limits. [Para 60][Para 100][Para 101] |
The court relied on it to reinforce the general agency principle and to reject the Applicant’s attempt to characterise the mistake as outside its control. [Para 99][Para 102][Para 103] |
| O'Riordan v An Bord Pleanála |
Cited by The Commission for the proposition that ignorance or misunderstanding of the limitation period does not justify an extension. [Para 61] |
The court treated this line of authority as supporting the refusal of time extension where the delay stemmed from a misreading of the deadline. [Para 61][Para 103] |
| Reidy v An Bord Pleanála |
Cited with O'Riordan for the same strict approach to limitation periods. [Para 61] |
The court used it as part of the respondent’s authority that misunderstanding the deadline is ordinarily insufficient to obtain relief. [Para 61][Para 103] |
| Irish Skydiving Club Ltd v An Bord Pleanála |
Quoted for the proposition that the time limit is strict and extensions must be strictly construed. [Para 75][Para 76] |
The court adopted that strict approach when assessing the Applicant’s request under section 50(8). [Para 75][Para 76][Para 120] |
| M O'S v The Residential Institutional Redress Board |
Cited for the broader discretion under “good and sufficient reason” and the need to consider all relevant facts and circumstances in the interests of justice. [Para 78][Para 81] |
The court accepted the general approach but held that the Applicant’s explanation did not objectively justify the failure to apply in time. [Para 77][Para 81][Para 117] |
| G.M. (Georgia) v The International Protection Appeals Tribunal |
Cited by the Applicant for a distinction between general reliance on lawyers and clearly wrong legal advice. [Para 89][Para 90] |
The court held that the litigant-in-person context in that case was not persuasive here and that the planning-law setting was materially different. [Para 91][Para 93] |
| S v Minister for Justice, Equality and Law Reform |
Cited as authority that delay by legal advisers is generally not prima facie a good and sufficient reason to extend time. [Para 97][Para 98] |
The court relied on it to support the conclusion that the solicitor’s mistake was not enough, without more, to justify relief. [Para 97][Para 102][Para 103] |
| Maguire v PSW Sales and Logistics |
Cited for the agency principle that a principal cannot take the benefit of a solicitor’s acts while rejecting the burdens. [Para 73] |
The court used this to reinforce that Company A could not distance itself from its solicitor’s error. [Para 73][Para 104] |
Court's Reasoning and Analysis
The court began by treating section 50(8) as requiring two separate conditions: good and sufficient reason, and circumstances outside the applicant’s control. [Para 21][Para 23] It then examined the Applicant’s explanation that the solicitor misread the decision date and incorrectly calculated the deadline, but noted that the Applicant itself had received the decision, the website showed the correct date, and no evidence explained what the Applicant did about the deadline. [Para 42][Para 44][Para 45][Para 46][Para 49][Para 52]
The court distinguished the authorities on which the Applicant relied, especially G and F.G., because those cases involved materially different facts and stronger interests-of-justice considerations. [Para 65][Para 71][Para 72] It held that the general rule remained that an applicant is bound by the acts and omissions of legal advisers, and that a delay caused by a solicitor’s mistake is ordinarily attributable to the client. [Para 73][Para 95][Para 98][Para 103]
The court also placed weight on the fact that the handwritten date on the decision was inconsistent with the date of receipt and that the error could have been detected over a long period before the deadline expired. [Para 106][Para 107][Para 109] It considered the absence of explanation about office systems, file management, or how the Applicant ignored the Commission’s explanatory letter as indicating that the circumstances were not fully or satisfactorily explained. [Para 110][Para 112][Para 117]
Although the delay was only eight days and the Applicant acted promptly once the mistake was discovered, the court held that those matters were outweighed by the failure to show a satisfactory reason and by the conclusion that the delay was not outside the Applicant’s control. [Para 119][Para 120] The court emphasized the legislative objective of certainty and finality in planning decisions and said that granting an extension would undermine the strict time limits imposed by the Oireachtas. [Para 120][Para 122]
Holding and Implications
APPLICATION REFUSED. The court held that Company A had not established good and sufficient reason, nor shown that the delay was outside its control, and therefore refused the extension of time. [Para 124] The direct consequence was that the Applicant’s attempt to seek judicial review out of time failed; the opinion applied existing strict time-limit principles and identified no broader implication beyond that result.
