Certification of Leave to Appeal in Planning Challenges: Delineating Pleading Requirements and Planning Judgment

Introduction

This commentary examines the High Court decision in Leech & Anor v An Bord Pleanala & Ors (Approved) [2025] IEHC 157, delivered on 24 March 2025 by Ms. Justice Emily Farrell. At issue was a planning application for a major residential development comprising 399 apartments within Dublin City’s Heuston South Quarter, located adjacent to Ireland’s iconic Royal Hospital Kilmainham. The case involved multiple parties, including the Applicants (Paul Leech and Frank McDonald), the Respondents (An Bord Pleanála, Ireland, and the Attorney General), and a Notice Party (HPREF SHQ Investments Limited). Central to the dispute were allegations that the Board’s decision violated provisions of the Development Plan by permitting a development which adversely affected a “protected view” (the cone of vision) and failed to adhere to the Planning and Development (Housing and Residential Tenancies) Act, 2016.

The Notice Party sought a certificate for leave to appeal on several questions primarily concerning the Board’s interpretation of the planning documents and the adequacy of the pleading in the judicial review proceedings. In so doing, the case aimed to clarify whether certain factual findings concerning “adverse impact” on the cone of vision could, under the ambit of a point of law, be certified for appeal to the Court of Appeal.

Summary of the Judgment

In the principal judgment, Justice Farrell quashed the grant of planning permission issued by An Bord Pleanála, primarily because the development was located within a protected zone – the cone of vision – as established in earlier planning documents and reinforced by the Development Plan. The judgment emphasized that any development adversely affecting a protected view must strictly comply with the relevant statutory requirements, including the invocation of section 9(6) of the 2016 Act when an adverse impact is found.

Specifically, the High Court found that the Board’s decision effectively confirmed an adverse impact on the cone of vision, even if its impact was characterized as “marginal” or “not very significant.” A core issue arose concerning whether the Applicants’ failure to specifically plead an interpretation of the Board’s decision (i.e. that it found an adverse impact) should preclude the Court from addressing that matter as a point of law. Ultimately, the High Court held that although a live controversy existed regarding planning judgment, the questions posed by the Notice Party were fact-specific, failed to rise to the level of “exceptional public importance,” and therefore did not warrant certification for an appeal under section 50A(7) of the Planning and Development Act, 2000.

Analysis

Precedents Cited

The judgment extensively refers to earlier cases and established principles that guide the certification of leave to appeal in planning disputes. Key precedents include:

Glancré Teoranta v An Bord Pleanála [2006] IEHC 250 – which originally set out the principles for considering certification of leave to appeal.
Monkstown Road Residents Association v. An Bord Pleanála [2023] IEHC 9 – whose summary was cited by the Court, reinforcing the cumulative criteria for certification.
Eco Advocacy v. An Bord Pleanála (No. 4) [2023] IEHC 713 – cited regarding proper pleading requirements in judicial review proceedings.
Casey v. An Bord Pleanála [2021] IESC 42 and Concerned Residents of Treascon and Clondoolusk v. An Bord Pleanála [2024] IESC 28 – which serve to underpin the “correct understanding” of judicial pleading and the underlying planning assessments.
Other cases such as Halpin v. An Bord Pleanála [2020] IEHC 218 and decisions in Stanley v. An Bord Pleanála [2022] IEHC 671 further emphasize that merely rearguing established legal principles does not suffice for a point of law of exceptional public importance.

These precedents contributed to the Court’s determination that the issues raised were either rooted in factual findings or simply a reapplication of well-settled legal norms, rather than a novel doctrinal matter warranting certification.

Legal Reasoning

The High Court’s legal analysis rested upon several key principles:

Pleading and Certiorari: The judgment clarified that although the Statement of Grounds must clearly specify the relief sought and the facts supporting it, a failure to plead every nuance of the Board’s interpretation does not automatically generate a point of law of exceptional public importance.
Interpretation of Planning Documents: The decision emphasizes the ordinary meaning approach—interpreting planning documents as a layperson would understand them—thus reinforcing that any determination about the “adverse impact” on a protected view is primarily a matter for planning judgment rather than a strict textual analysis.
Cumulative Requirements for Certification: The Court rigorously applied the multiple criteria outlined in section 50A(7) related to certification. It stressed the need for the point of law to not only arise directly out of the High Court decision but also to have genuine potential to influence broader jurisprudence. Since the issues under debate were fact-specific and had limited scope to change established planning jurisprudence, they did not meet the stringent threshold required for certification.
Role of Planning Judgment: Emphasis was placed on the inherent discretionary element in planning decisions. While planning authorities must adhere to statutory mandates, the ultimate determination of what constitutes an “adverse impact” lies in the exercise of planning judgment—a decision inherently grounded in factual assessments rather than abstract legal principles.

In summary, the Court’s reasoning underscored that even if there were a hypothetical misapplication of principles as set out in Casey or Eco Advocacy, that alone would not establish a point of law that is sufficiently “exceptional” to justify an appeal certificate. The analytical rigor provided by the Court ensured that judicial review of planning decisions remains confined to factual disputes rather than becoming a vehicle for re-litigating broad planning policy issues.

Impact on Future Cases and the Field of Planning Law

This judgment is significant in several ways:

Clarification on Pleading Requirements: The decision reinforces that proper pleading in judicial review must be sufficiently clear to frame the contentious issues, but it does not require an exhaustive dissection of every nuance of a Board decision. Future litigants will now understand that failure to explicitly plead an interpretation is unlikely to itself constitute grounds for certification.
Limits on Certification for Appeal: By confirming that a point of law must be not only novel but also of exceptional public importance, the judgment sets a high hurdle for obtaining certification to appeal. This may deter appeals that aim primarily to rehash established principles rather than address any genuine and far-reaching legal uncertainty.
Role of Planning Judgment: The emphasis on the exercise of planning judgment means that courts will continue to defer to the expertise of planning authorities when determining issues like adverse impacts on protected views. This is likely to preserve a degree of deference towards planning bodies, so long as they stay within statutory limits.
Future Jurisprudence: While litigation in planning matters is frequent, this decision suggests that only cases with truly significant legal uncertainty or potential for broader doctrinal development will succeed in obtaining certification for appeal. Courts will be cautious in opening the floodgates for appeals based on what are essentially factual adjudications masked as legal errors.

Complex Concepts Simplified

Pleading Requirements: In judicial review, a Statement of Grounds must clearly outline the factual and legal basis for the claim. However, litigants are not required to exhaustively detail every possible nuance of the opposing decision as long as the key points are identified clearly.

Protected View (Cone of Vision): The “cone of vision” refers to a designated view protected under the Development Plan. The planning authorities are tasked with ensuring that new developments do not detract from this view, although determining what constitutes an "adverse impact" involves a degree of professional judgment.

Certification for Leave to Appeal: Certification is a judicial mechanism that allows an appeal to be heard in higher courts only if the point of law is not only novel but also carries exceptional public importance. This ensures that the appellate system is not overburdened by challenges that merely reassert established facts or interpretations.

Planning Judgment: This is the discretion exercised by planning authorities when interpreting statutory provisions. The judgment emphasizes that many disputes about development impacts are not meant to be re-assessed in appellate courts because they are largely based on factual assessments and subjective interpretation.

Conclusion

Justice Farrell’s decision in Leech & Anor v An Bord Pleanála & Ors clarifies that while the principles underlying judicial review pleadings and planning decisions are well established, a challenge grounded solely on a perceived misapplication of these principles does not suffice to generate a point of law of exceptional public importance. The Court reinforced that questions arising from factual decisions—such as the interpretation of whether a development adversely impacts a protected view—are ultimately matters of planning judgment and must be adjudicated on their merits.

This ruling will serve as an important precedent by limiting the scope for appeal certification in planning disputes and emphasizing that only those questions that possess a broad, transformative impact on the interpretation of planning law should be considered for higher appellate review. It reiterates the judicial reluctance to disturb factual determinations unless there is a clear misapplication of legal principles.
