Wind farm developer awarded 50% of legal costs in landmark Supreme Court challenge

Ruling made clear climate obligations were real, effective, and, if necessary, enforceable

Last month, the seven-judge court upheld a High Court order that overturned An Coimisiún Pleanála’s 2024 refusal of planning permission for Coolglass Wind Farm Ltd’s project. File picture: Denis Minihane

A wind farm developer has been awarded 50% of its legal costs incurred in a landmark Supreme Court challenge related to climate law obligations of planning authorities and public bodies.

Last month, the seven-judge court upheld a High Court order that overturned An Coimisiún Pleanála’s 2024 refusal of planning permission for Coolglass Wind Farm Ltd’s project, but for reasons different and narrower than those cited by the lower court.
