Busher and Ors v An Coimisiun Pleanala and Anor [No. 3] (Approved)

Factual and Procedural Background

The Applicants challenged permission granted by the Respondent Commission for a foul pumping station, wastewater treatment plant and associated works in a coastal town. The High Court previously upheld the permission after administrative scrutiny and proceedings concerning the development. [1][2][3]

The Applicants applied for leave to appeal. Written submissions were exchanged, the application was heard, and judgment was reserved. [4][5]

Legal Issues Presented

1. Whether the Applicants could raise an issue concerning the interpretation of legislation or regulations in judicial review proceedings despite not addressing the legislation in their submissions to the administrative decision-maker. [6][7]
2. Whether a condition requiring compliance with one regulation was sufficient to comply with another regulation. [8]
3. Whether either proposed question satisfied the statutory requirements for leave to appeal, including being a point of law of exceptional public importance and an appeal desirable in the public interest. [9][10][11]

Arguments of the Parties

Applicants' Arguments

• The Applicants proposed the two questions identified above and argued that the judgment restricted their ability to challenge the legality of the decision. [6][12]
• They asserted that the judgment conflicted with other authorities, engaged the Aarhus Convention, and created uncertainty concerning the relevant regulations. [13][14][15]
• They advanced complaints concerning odour, licensing, infrastructure delivery and the weight given to wastewater infrastructure. [16]
• They argued that the project’s urgency should be discounted because of alleged delay by the Notice Party and disputed the effect of the existing discharge on water quality. [17]

Respondent Commission's and Notice Party's Arguments

• The Respondent submitted that the Applicants had been permitted to raise and argue their interpretation point, which had simply been rejected. [18][19]
• It argued that the first proposed question misrepresented the judgment and that the second was a merits-based application of law to particular facts, not a pure point of law. [19][20]
• The Respondent and Notice Party argued that the proposed questions were not determinative because the substantive challenge had failed on several independent grounds. [21][22]
• They submitted that the project addressed the ongoing discharge of untreated wastewater and that further delay was contrary to the public interest. [23][24][25]
• The Notice Party submitted that the application merely reargued the unsuccessful case and did not engage with the reasoning of the principal judgment or identify a legally significant uncertainty. [16][26]

Court's Reasoning and Analysis

The court began with the statutory criteria for leave to appeal. A proposed question must arise within the pleadings, arise on the facts, have been argued below, be capable of affecting the result, accurately reflect the judgment, be timely and specific, and constitute a point of law of exceptional public importance. The appeal must also be desirable in the public interest. [9][33][37][38][39][40][63][64][10][11]

The first proposed question did not properly arise because it inaccurately suggested that the Applicants had been barred from raising statutory interpretation issues. The Applicants had raised the regulatory interpretation point, but the court had rejected it. [7][18][19]

The court held that the validity of the administrative decision had to be assessed primarily through the evidence and submissions before the decision-maker. Allowing decisive new evidence or merits arguments at judicial review stage would transform review of legality into reconsideration of the correctness of the decision, contrary to the separation of powers. [57][15]

The second proposed question did arise, but it was not a pure question of law. It concerned the application of an evaluative regulatory provision to the particular facts and effectively sought to reargue the merits of the planning decision. [65][66][20][67]

Neither question was of public importance. The first did not arise, while the second concerned a provision that left the form of any necessary condition to the Commission's evaluative judgment and generated no genuine legal uncertainty. [68][69][70]

The questions were also non-determinative. The substantive judgment had rejected the challenge on several independent grounds, including failure to raise the relevant complaint in the planning process, the overstated effect of the regulations, the lawfulness of the condition, lack of demonstrated legal or evidential failure, and discretionary considerations. Those grounds would remain even if the proposed questions were answered in the Applicants' favour. [21][22][71]

Finally, an appeal was not desirable in the public interest. The statutory scheme favoured finality, certainty and expedition in planning judicial review, while the project addressed the ongoing discharge of untreated wastewater into coastal waters. Further litigation would delay infrastructure regarded as environmentally important, without any demonstrated countervailing public benefit. [72][62][52][25][73][26]

Holding and Implications

APPLICATION FOR LEAVE TO APPEAL DISMISSED. The court ordered that, if leapfrog leave were granted by the Supreme Court, the costs of the leave application would be costs in that appeal; otherwise, there would be no order as to those costs. [74][75][76][77]

The substantive proceedings also remained dismissed, with no order as to costs, and the orders were to be perfected as the final order of the High Court. [78][79][80][81]

The direct effect was that the permission remained in place and no further High Court appeal proceeded. The opinion applied existing principles concerning leave to appeal and did not state that it created a new precedent.
