Yesterday, An Bord Pleanála consented to the overturning of planning permission previously given to College for the expansion of Trinity Hall (Halls).
The accommodation complex had received the green light by An Bord Pleanála in August for the addition of 358 student beds into the complex, which has been overturned following an appeals case.
The planning permission also applied for four staff apartments on the complex.
Patricia Kenny, who is a resident close to Halls in Dartry, took the proceedings to the High Court.
An expansion of the accommodation complex had been previously objected to before the planning permission being given, with residents of Dartry complaining about student behavior in the area.
Back in June, residents of Dartry moved to block the proposed bed spaces in Halls over allegations of drunken behavior, such as urinating on the street, shouting, and leaving empty bottles and cans outside, as reported by the Irish Examiner.
The core claim yesterday by Mrs Kenny was whether the development required an Environmental Impact Assessment, arguing that An Bord Pleanála had wrongly treated it as a standalone development rather than one linked to existing accommodation at Halls.
Despite a board inspector saying the environmental report submitted by Trinity “identified and adequately” described the environmental effects of the development and an EIA was not required, the planning permission has been overturned.
