Flexibility in Appeals from Ex Parte Leave Refusals and Scrutiny of CPO Rationales: Heavey v An Bord Pleanála [No. 2] [2025] IEHC 311

Introduction

Angela Heavey owns property adjacent to the protected Swords Castle. Fingal County Council made a compulsory purchase order (CPO) in November 2022 to acquire her land for the Swords Cultural Quarter. Heavey applied ex parte for leave to seek judicial review of the board’s confirmation of that CPO but omitted the inspector’s report from her application. Holland J refused leave. She then sought leave to appeal to the High Court. Humphreys J was asked to decide not only whether certification for appeal of an ex parte refusal should allow new evidence or amendment of pleadings, but also whether two substantive rationales for the CPO—(i) her property as the sole “oasis” of unacquired land beside the castle and (ii) enhanced public views of the monument—could sustain substantial grounds for review.

Summary of the Judgment

The High Court granted leave to appeal, certified five questions and continued the stay on the CPO pending determination by the Court of Appeal. The Court held:

Appeals from refusal of ex parte leave are not rigidly confined to error review; historically they have allowed fresh evidence or pleadings amendment akin to a renewed application.
O. 86A r. 4(b) of the Rules of the Superior Courts incorporates interlocutory flexibility for admitting fresh evidence in appeals—even if obtainable originally.
Two substantive issues warranted certification: whether reliance on Heavey’s land as the only “oasis” beside the castle was correct when other private lands adjoin the monument, and whether reliance on “opening up” views was undermined when new buildings were ultimately proposed on that land.

Legal Reasoning

Section 50A(7) of the Planning and Development Act 2000 provides that no appeal lies from a High Court decision on leave or on judicial review except where the High Court certifies a point of law of exceptional public importance. The Council argued that identical strict criteria apply whether leave was granted ex parte or after inter partes hearing. The Court disagreed. Drawing on historic Supreme Court practice and RSC O. 86A r. 4(b), it held that appeals from ex parte refusals often function as fresh applications, permitting limited admission of new evidence and pleadings amendment to prevent personal litigants from undue prejudice.

On substance, the Court examined the inspector’s report which repeatedly referred to Heavey’s site as “the only ‘oasis’ of land not controlled by the Council” beside the eastern curtain wall of Swords Castle. It noted that other privately owned properties adjoin the castle on different flanks. Second, the report praised the CPO for “opening up” views of the castle, yet the masterplan itself contemplated erecting new cultural buildings on Heavey’s land. In both respects, the Court found arguable legal grounds— irrationality or lack of necessity/proportionality—that warranted certification for appeal.

Impact

This judgment clarifies that:

Appeals from refusals of ex parte leave applications may admit fresh evidence and amendment of pleadings within limits, aligning them more closely with renewed leave applications than strict error reviews.
Personal litigants in judicial review must nonetheless meet reasonable pleading and evidential standards, or face refusal of leave.
Public bodies must articulate CPO rationales precisely—claims of exclusivity of land or visual benefits must cohere with the broader development context or face challenge on necessity/proportionality or irrationality.

Complex Concepts Simplified

Ex Parte Leave Application: Applying for leave to seek judicial review without notifying the other party at that stage.
Section 50A(7) Certification: A formal High Court certificate that an appeal involves a point of law of “exceptional public importance,” enabling an appeal to the Court of Appeal.
Interlocutory Appeal Flexibility: Under RSC O. 86A r. 4(b), fresh evidence may be admitted on appeal from interlocutory orders (such as leave refusals).
Substantial Grounds: The threshold in a leave application requiring credible arguable legal errors in an administrative decision.
Compulsory Purchase Order (CPO): Statutory power of a public authority to acquire private land for public purposes, subject to judicial review on strict criteria.

Conclusion

Heavey v An Bord Pleanála [No. 2] is a landmark on procedural fairness in judicial review leave appeals and on the scope of appeals from ex parte refusals. It confirms that such appeals may, in limited circumstances, be treated as fresh applications permitting supplemental evidence and pleadings amendment to avert disadvantage to personal litigants. Substantively, it demonstrates that courts will scrutinise CPO rationales—especially claims of exclusive need or visual enhancement—for coherence with the overall scheme and object to irrational or unsupported grounds. This decision will guide future litigants and public authorities in framing and defending ex parte leave applications and CPOs alike.
