Carrickmines Castle Protestors' bid fails
The decision by Mr Justice Lavan clears the way for Dun Laoghaire/ Rathdown County Council to remove the castle's perimeter wall and complete construction of the M50 motorway.
Legal awards were awarded against protestors Gordon Lucas and Dominic Dunne but the order was stayed for 21 days to allow for an appeal.
Earlier, the High Court was told that Dun Laoghaire-Rathdown Council had driven a coach and horses through the National Monument Act in its dealings with the medieval site.
The court heard how the site probably dates back to the 13th Century and has a unique defensive feature of a stone-covered perimeter wall.
Farnk Callinan SC for the protestors said the Council didn't have the basic legal authority to carry out its plan to relocate the wall in order to facilitate a roundabout off the M50.
He said the Council didn't have the required written consent of the Commissioners of Public Works under the ammended Natioanl Monuments Act, nor the required excavation licences.
