Justice Paul McDermott ruled that Apple should be granted permission to build the data centre on Ireland's west coast.
The data centre project has been plagued by delays since it was announced in 2015.
"In light of the time that it took to arrive at this decision we will have to take a critical look at this whole process because the way it stands it is far too slow and is a threat to employment and the economy in general".
That decision was re-affirmed by An Bord Pleanála in August 2016 - however the project has been delayed by a judicial review undertaken by three objectors to the project. It also appeared that the majority of the local population was in favor, given the jobs and income the center would bring to the area.
