• An Bord Pleanála appeal, now An Coimisiún Pleanála — four weeks, €220, and a 25% reversal rateThe Commission reversed the council in 25% of the 1,195 Dublin-area appeals decided in the two years to September 2026. Who can appeal, the four weeks, the €220 fee, why 240 appeals a year fail on procedure, and the odds by direction.
• Appeals overturned by council — how often An Coimisiún Pleanála reverses each Dublin council, and in which directionThe Commission reversed the council on 301 of 1,195 Dublin appeals decided in 24 months, 25%. South Dublin was reversed most (30%), Dublin City least (23%), and 76 of Fingal's 85 reversals turned a refusal into a grant. How the appeal works, what a reversal rate means, and how to read your council's number before you appeal.
• Judicial review of a planning decision in Ireland — eight weeks, substantial grounds, and who may bring oneThe Commission decided 510 appeals from the seven Dublin-area councils in the 12 months to September 2026, and each opened an eight-week judicial review window. What s.50 allows, what it costs, what the court can and cannot do, and how the 2024 Act changes standing.
• Data centre planning applications in Dublin — what the register holds and what is exemptFifteen data-centre applications reached the Greater Dublin registers in 36 months, 11 granted and 3 refused, almost all of them at Grange Castle, Profile Park and Citywest in South Dublin. Most are not new buildings but extensions of duration, section 5 declarations for generators and platforms, and the network gateways that feed the campuses. What each kind of file means, where the EIA and grid questions sit, and every file linked.
