Background
Cork County Council applied for planning permission to upgrade an existing 2-kilometre pedestrian and cycle route in Passage West, County Cork. An Coimisiún Pleanála (the planning appeals authority) granted permission with conditions in July 2025. Three residents—Marcia D’Alton, Mella Leonard, and Norma Lombard—challenged the decision by judicial review, arguing that it failed to properly protect a historic wall and stile and did not adequately address impacts on an existing car park. In the principal judgment, the High Court found the decision legally defective on these grounds and quashed the permission in part.
The present judgment addresses the consequential issues: the precise scope of the quashing, whether to amend the decision, whether to remit the matter to the planning authority for reconsideration, the stage to which remittal should apply, and procedural questions about handling the inspector’s report in a remitted process. The court was asked to decide, among other things, whether partial quashing of a planning decision allows remittal, or whether remittal is appropriate only when an entire decision is quashed.
The Court’s Holding
The court ordered that the quashing be limited to (1) the demolition of the historic wall and stile (preserving them in place), and (2) the widening of the greenway where it would affect the car park (preserving the car park). This represented a compromise acceptable to the applicants and the council. The court then turned to the question of remittal. Under section 50A(9A) of the Planning and Development Act 2000 (as amended in 2022), when a court quashes a planning decision and the developer requests remittal, the court “shall” remit the matter to the planning authority unless doing so would be unlawful. The applicants argued that this provision does not apply to partial quashing—that remitting only the quashed portions would remove the decision from its proper context. The court rejected this argument, holding that the statute’s language is capable of covering partial quashing, and that the statutory presumption in favour of remittal applies.
The court reasoned that remitting the quashed parts is no more “out of context” than the realistic alternative: requiring the developers to file a completely new application for those portions. Moreover, Irish law permits development to be consented in parts, provided that environmental impact assessments and habitats assessments cover the full project at each stage. The court therefore ordered remittal to An Coimisiún Pleanála. Exercising restraint consistent with recent Supreme Court guidance, the court did not specify the stage to which remittal should occur. However, the court requested that the commission clarify how it would procedurally handle the remitted matter—specifically, whether the original inspector’s report would be included in the remitted file and whether it would be considered in reconsidering the decision.
Key Takeaways
- Partial quashing of a planning decision does not preclude remittal; the statute mandates remittal when the developer requests it, unless remittal would be unlawful.
- A developer’s statutory right to remittal extends to cases where only part of the original planning decision has been quashed.
- Remitting only the quashed portions does not violate contextual planning principles; a new standalone application for those portions would be equally fragmented.
- Irish planning law permits development to be approved in phases or parts, provided environmental and habitats assessments examine the full project scope at each stage.
- Courts should exercise restraint in specifying remittal procedures, trusting planning authorities to comply with law and fair procedures.
- Clarity about the treatment of original inspector’s reports and other documents in remitted matters is essential for procedural fairness.
Why It Matters
This judgment resolves a significant question about Irish planning law: when a court partially quashes a planning decision, is the developer entitled to have the quashed portion remitted to the planning authority for reconsideration? The 2022 amendment to section 50A(9A) was enacted to ensure courts remit quashed decisions when requested, reversing what was perceived as judicial reluctance to do so. This judgment confirms that remittal is available even for partial quashing, meaning developers typically will not be forced to file entirely new applications when only discrete parts of a decision are found legally defective.
Practically, the decision provides important guidance for planning authorities, developers, and applicants about the consequences of partial quashing in judicial review cases. For planning authorities, it underscores the need for procedural clarity when reconsidering remitted matters—particularly regarding what documents and prior decisions will inform the reconsideration process. The judgment also reinforces a principle of deference: Irish courts will respect planning authority decision-making provided authorities follow law and fair procedures, without attempting to micromanage remitted proceedings through detailed judicial directions.
