Justice Paul Carney fears that a planned extension to his next door neighbour's house will reduce the light coming into his study.
He is appealing the planning permission which was granted to his next door neighbours in Dublin for a new extension and refurbishment works.
The judge (inset) and his wife, a lawyer, lodged an objection with Dublin City Council last year over the plans.
The council granted planning permission last December.
However, an Bord Pleanala will now rule on the planning appeal over the coming months.
The submission by Mr Carney said they believed the rear extension to their next door neighbour's house would reduce the light into a number of rooms, "namely the kitchen window, dining room window, study window, shower room window and utility room window."
"The principal source of light in the study where we do our legal work is provided by a window which looks out onto the party wall," it said.
In the document, they also questioned the need for an extension to the rear of the house, leaving a small rear garden.
The planning appeal case is now due to be decided by An Bord Pleanala by May 5.
