Circuit Court judge Brian Curtin is to appeal the High Court's rejection earlier this month of his challenge to the proposed Oireachtas investigation into his affairs.
Judge Curtin lost a challenge to the Oireachtas authority to gather evidence in a High Court judgment delivered on May 3rd by Mr Justice Thomas Smyth.
It emerged this evening that lawyers for Mr Curtin have lodged appeal papers at the Supreme Court.
Mr Curtin claimed in the High Court that the procedures adopted by the Houses of the Oireachtas had failed to provide a mechanism by which facts could be found which might constitute stated misbehaviour.
In April 2004, Judge Curtin was acquitted, by direction of a judge at Tralee Circuit Court, on a charge of possessing child pornography. The acquittal came when it emerged that a warrant under which Judge Curtin's computer was seized was out of date.
