Save the South Leinster Way and Tara Heavey v An Bord Pleanala (Approved)

Factual and Procedural Background

The Appellants – an environmental NGO and its chairperson – sought judicial review of a decision by the planning authority (“Respondent”) granting permission for a 21-turbine wind-farm near a long-distance walking trail. Under s. 50(6) of the Planning and Development Act 2000 (“the 2000 Act”) an application for leave had to be made within eight weeks of the decision (26 September 2022). Because the eighth week expired on Sunday 20 November 2022, the Appellants filed their papers on Monday 21 November 2022. The High Court held that the filing was out of time, refused to extend time under s. 50(8) and dismissed the proceedings. The Supreme Court (per Judge Donnelly) granted a leap-frog appeal to determine whether, at common law, statutory time-limits that expire on a non-working day are deemed to expire on the next court business day.

Legal Issues Presented

1. Whether, in the absence of an express statutory provision, a common-law presumption extends the eight-week judicial-review limit in s. 50(6) of the 2000 Act to the next working day when the last day falls on a day the court offices are closed.
2. If the presumption does not apply, whether the Appellants satisfied the statutory test in s. 50(8) for an extension of time.

Arguments of the Parties

Appellants’ Arguments

• The common-law rule in Pritam Kaur and its adoption in Poole v O’Sullivan applies to all statutory time-limits that require court action; therefore the period expired on Monday 21 November.
• High Court precedent (Max Developments v An Bord Pleanála) already applied the same principle in planning judicial review.
• EU law (Aarhus Convention, EIA Directive) and the principle of effectiveness favour an interpretation that avoids additional curtailment of an already “very short” eight-week period.
• Even if technically late, an extension of time should be granted: the weekend closure was outside their control and no prejudice to the developer was shown.

Respondents’ Arguments (Planning Board, State and Notice Party)

• The eight-week limit in s. 50(6) is intended to be strictly applied to ensure certainty for developers and the public; extensions are permissible only under s. 50(8).
• Other sections of the 2000 Act (e.g. ss. 141, 251) and company-law statutes show that when the Oireachtas wished to displace expiry on a non-working day it did so expressly; the maxim expressio unius est exclusio alterius therefore applies.
• Poole v O’Sullivan concerns limitation periods in personal-injuries actions and is not authority for public-law jurisdictional time-limits.
• It was “possible” to present the application earlier (e.g. serve unstamped papers or approach the duty judge); the situation was not one of impossibility or excessive difficulty.
• EU law does not require a different result; this Court has already upheld the compatibility of the eight-week limit with EU principles (Krikke).

Court’s Reasoning and Analysis

Judge Donnelly applied the modern Irish approach to statutory interpretation, weighing language, context and purpose:

• Common-law backdrop: For over a century Irish court rules (Order 122 r. 3 and predecessors) and authorities such as Hughes v Griffiths established that where court offices are closed, time for acts requiring court action carries forward. This rule was expressly adopted in Ireland in Poole v O’Sullivan and had already been applied to planning JR in Max Developments.
• Legislative context: When enacting the strict eight-week limit in 1992 and reenacting it in 2000, the Oireachtas legislated against that settled backdrop and did not expressly displace the presumption. By contrast it did legislate expressly for other timing adjustments (e.g. Christmas “disregarded days”) where needed.
• Purpose and certainty: Applying the presumption does not undermine legal certainty; it provides a clear, predictable rule known from the outset (anyone can see a deadline will fall on a weekend). Moreover, the 2000 Act already allows discretionary extensions, so absolute immutability was not its purpose.
• “Impossibility” test: The Court rejected the Respondents’ argument that the Appellants could have approached a duty judge. Practicality, not theoretical possibility, governs; the Practice Direction requires prior filing in the Central Office, which was impossible when the office was closed.
• Policy considerations: Commercial certainty and expedition remain important, but the forthcoming s. 281 of the 2024 Act – which codifies the same roll-over rule – demonstrates legislative acceptance that such an adjustment is compatible with planning policy.
• EU law: Because the domestic presumption resolved the appeal, EU-law points (effectiveness, Aarhus) were unnecessary to decide.

Holding and Implications

HELD: Appeal Allowed. The eight-week period in s. 50(6) is construed so that, when the last day falls on a Saturday, Sunday or court holiday, it expires on the next day the court offices are open. The Appellants’ application on Monday 21 November 2022 was therefore timely; no extension of time was required.

Implications: The decision restores and clarifies the common-law presumption for all planning judicial-review time-limits until commencement of s. 281 of the 2024 Act (which will put the same rule on a statutory footing). It reinforces a purposive yet contextual approach to Irish statutory interpretation without creating a new substantive precedent on EU-law effectiveness.
