The High Court has dismissed Ailsa Sexton’s challenge to An Bord Pleanála’s refusal of permission for a dwelling linked to an equestrian business at Wyanstown, Oldtown, Co. Dublin. The court found the Commission’s reasons adequate when read alongside Fingal County Council’s earlier decision and the planning file.
Mr Justice David Holland delivered the judgment on 31 July 2025. The Commission had granted permission for the equestrian facilities but refused the residential element: a proposed house and temporary relocation and retention of a mobile home. Ms Sexton sought judicial review only of the refusal of the residential element, arguing principally that the Commission had not adequately explained why it disagreed with its inspector, who recommended granting permission.
The relevant Fingal Development Plan policy required an applicant seeking a rural home on the basis of a full-time, home-based business to demonstrate long-term commitment and provide legal documentation showing sufficient funding to start and operate the business. The plan also required a sworn affidavit. The application included a business plan, but the court noted that it did not include the affidavit or legal documentation about committed funding. The appeal did not supply those documents either, despite the Council having identified their absence when refusing the application.
The Commission refused the house because adequate documentation had not demonstrated Ms Sexton’s long-term commitment to operate a full-time business from the rural home. In disagreeing with the inspector, it referred to the totality of the information on file and the lack of sufficient information to support the claim that the enterprise would sustain full-time employment.
The judge said the Commission had not found that the business could not sustain full-time employment; it had found that Ms Sexton had not demonstrated that it would. Read pragmatically alongside the Council’s decision and planner’s report, the Commission’s reasons made the main grounds for refusal clear, including the missing affidavit and funding evidence. The court therefore rejected the reasons challenge and dismissed the proceedings.
The judgment also said the Commission could have sought the documents through a further-information request, and described that as a practical course in the circumstances. But the judge made clear that this observation concerned good practice, not the legality of the decision. The refusal was based on missing documentary proof rather than a determination of the proposal’s planning merits. The court said the circumstances appeared to permit a fresh application accompanied by the missing documents, but made no prediction about whether it would succeed.
