An appeal by businessman Denis O’Brien against the High Court’s dismissal of his action over statements made in the Dáil about his banking affairs will begin in the Supreme Court this morning.
Mr O’Brien is appealing against the High Court’s decision that it had no power to rule on issues raised by him about how the Dáil’s Committee on Procedure and Privileges dealt with the statements and with his complaints.
He is also appealing against an order directing him to pay the costs of his failed High Court case.
In April 2015, Mr O’Brien was granted an injunction against RTÉ in relation to a proposed broadcast about his banking affairs.
He says Social Democrats TD Catherine Murphy and Sinn Féin TD Pearse Doherty then revealed information on the floor of the Dáil, which rendered the injunction almost pointless.
