Background
Andrew Clarke received a €2,400 SEAI (Sustainable Energy Authority of Ireland) grant for a micro-inverter solar PV system. Following inspection, SEAI issued a Re-Works Notification requiring an emergency isolation/shunt switch, claiming the device was mandatory under I.S. 10101 (an electrical standard) and the SEAI Code of Practice.
Clarke disputed this internally with SEAI, then complained to the Ombudsman. His core argument: micro-inverter systems automatically shut down when mains power is lost, making additional isolation devices unnecessary. He further contended that NSAI Agrément Certificates for compliant micro-inverter systems did not show the emergency isolators SEAI required, suggesting SEAI had misinterpreted or exceeded the regulatory requirements. The Ombudsman rejected his complaint on 25 February 2025, accepting SEAI’s interpretation that emergency isolation is required for all PV configurations, including micro-inverter systems.
Clarke sought judicial review of the Ombudsman’s decision, alleging procedural unfairness, jurisdictional error, and failure to address material arguments. On the interlocutory applications before Justice Siobhán Phelan, Clarke applied for a protective costs order to shield himself from the Ombudsman’s estimated €30,000 legal costs.
The Court’s Holding
Justice Phelan denied Clarke’s protective costs order application. The court found this to be a private dispute concerning Clarke’s own grant and installation, not public-interest litigation. Although the legal issues might have relevance to other solar grant recipients, that alone does not elevate the case to the status of exceptional public-interest litigation warranting costs protection. The court noted the €2,400 grant amount was modest and the Code of Practice was a clear condition of participation in the grant scheme, which Clarke had agreed to when applying.
The court rejected Clarke’s argument that resource inequality between a retired individual and a State-funded body justified exceptional costs protection. It held that State funding of respondents in judicial review is common and does not alone warrant departing from ordinary costs rules. The court emphasized that costs exposure serves the important function of discouraging weak or unmeritorious litigation. While acknowledging that Clarke’s substantive arguments about the Ombudsman’s jurisdiction and fair procedures may raise some arguability, the court found insufficient merit and public importance to justify costs protection.
On the discovery application (seeking disclosure of all Ombudsman-SEAI communications), the opinion addresses Clarke’s contentions at length but does not contain the final ruling, as the text cuts off mid-decision.
Key Takeaways
- Protective costs orders are exceptional departures from normal costs rules, reserved for genuine public-interest litigation—not cases where a private individual’s grievance may incidentally affect others.
- Resource disparity between an individual litigant and a State-funded respondent is relevant but insufficient alone to justify costs protection in the absence of public-interest significance.
- The court recognized arguable points in Clarke’s challenge regarding Ombudsman jurisdiction and fair procedures but found the case fundamentally concerned his private circumstances, not a matter of general public importance.
- Conditions of grant schemes (such as compliance with codes of practice) that applicants agree to as a condition of participation are binding even if their underlying technical justification may be disputed.
Why It Matters
This decision establishes guidance on when judicial review will receive costs protection—a critical gate for litigants of modest means. While Clarke raised potentially important questions about the Ombudsman’s procedural fairness obligations and its willingness to address technical arguments, the court’s holding treats his case as a private dispute rather than a vehicle for resolving matters of systemic public importance. For solar grant applicants and other Ombudsman complainants, the decision suggests that judicial review of Ombudsman decisions on procedural grounds may proceed without costs protection unless the dispute itself (not merely its incidental consequences) engages public-law principles of broader significance.
The underlying technical dispute—whether micro-inverter solar systems require emergency isolation devices under Irish electrical standards—remains unresolved by this interlocutory ruling, as does the substantive judicial review of the Ombudsman’s decision-making process and fair procedures obligations.
