The High Court has quashed permission for a 170-home development at Cartron and Garraun South, Oranmore, after finding that An Coimisiún Pleanála did not properly address departures from the Garraun Urban Framework Plan.
The project by Marshall Yards Development Company Limited also included a crèche, pedestrian and cycle works along the R338 towards Oranmore rail station, parking, landscaping and associated infrastructure.
Galway County Council refused the original 171-unit proposal in August 2024 for five reasons, including traffic, urban-design and development-plan concerns. The developer appealed with a revised 170-unit scheme.
A planning inspector also recommended refusal. However, the commission decided by a 2-1 split in January 2025 to grant permission subject to 22 conditions.
Neighbouring resident Mark MacSweeney challenged that decision.
Mr Justice Humphreys focused on the commission's treatment of the Garraun Urban Framework Plan, which forms part of the Galway County Development Plan. The inspector had identified several differences between the plan's indicative layout and the proposed scheme, including the absence of a single continuous east-west street, the lack of the planned green spine, differences in frontage to the R338 and reduced connectivity at the western end of the site.
The judge held that planning law required the commission to engage with the relevant plan provisions, decide with reasons whether each departure amounted to a contravention, decide whether any contravention was material and, if necessary, apply the statutory rules governing permission despite a material contravention.
The commission had not completed that analysis. In some instances it did not engage with the relevant plan text; in others it moved directly to whether the development was acceptable without first resolving contravention and materiality.
The permission was therefore quashed.
The judgment does not rule that the 170-home scheme must be refused. Other challenges, including several environmental grounds, were left undecided, and similar issues may be raised again in future proceedings or any revived planning process.
