The four, Nora Bennis from Limerick, Harry Rea from Blarney Road in Cork, Mark McCrystal from Swords in Dublin and Richard Behill from Killarney, Co Kerry were told by Mr Justice Sean Ryan that their case contained technical legal points with which he disagreed.
He said the case was also 'based on politics and not law' and provided no legal basis on which to seek a judicial review of the result of the Referendum.
The court heard the four were seeking to have the result of the referendum declared null and void, a declaration that the Government had acted unlawfully by failing to lay the guarantees before the Oireachtas and that the amendment was repugnant to the Constitution.
