McAleenon, Application for Judicial Review (Re Nuisance Odour and Pollution Arising from Mullaghglass Landfill Site) [2025] NICA 44 (16 September 2025)

Executive summary

The Court of Appeal in Northern Ireland considered Ms McAleenon’s judicial review challenge concerning alleged nuisance odour and pollution from Mullaghglass landfill site. It reviewed whether Lisburn and Castlereagh City Council, the Northern Ireland Environment Agency, and the Minister/DAERA had failed in their statutory and Article 8 duties, against a background where the site was already closed and complaints had diminished.

Key points

• Appellant: Noeleen McAleenon; respondents: Lisburn and Castlereagh City Council, the Northern Ireland Environment Agency, and the Minister/DAERA; Alpha Resource Management Ltd was the notice party.
• The court identified three appeal issues: alleged breach of the council’s duty to investigate statutory nuisance, alleged unlawful failure by NIEA/DAERA to identify a lifetime H2S exposure risk, and alleged Article 8 ECHR breaches.
• The judgment recites the earlier findings that the council investigated, referred matters to the NIEA, and concluded there was no statutory nuisance; the NIEA/DAERA claim was framed as one turning on Wednesbury irrationality.
• It also records that the appellant had previously been found to have an alternative remedy, but the Supreme Court remitted the case so the merits could be determined in judicial review.
• The source text provided does not include the court’s final disposition on the merits, so no sanctions or export-control issue is identified in the judgment itself.

Why it matters

This is not a sanctions or export-control case; its relevance for geopolitical or sovereign-risk analysis is indirect, as it concerns environmental governance, regulator performance, and the scope of public-law remedies. For compliance and enforcement audiences, it illustrates how courts frame challenges to regulator inaction and assess whether agencies have exercised statutory discretion rationally.

Implications

For litigation strategy, the case shows the importance of selecting the proper forum and remedy when challenging alleged regulatory failures, especially where judicial review is used to test public-law duties rather than to relitigate technical evidence. For compliance and enforcement, it underscores that documented investigations, information-sharing, and monitoring can be central in defending against claims that a regulator abdicated its statutory responsibilities.
