THE SUPREME COURT has ruled that Denis O’Brien’s privacy was not breached during a 2015 debate about the sale of Siteserv. The judgement was delivered by Mr Justice Frank Clarke at a sitting of the Supreme Court in NUI Galway this morning. The judgement came on foot of an appeal by the businessman against a High Court decision from May 2017, when Ms Justice Úna Ní Raifeartaigh ruled in favour of the Clerk of the Dáil and the Dáil Committee on Procedures and Privileges (CPP). O’Brien had argued that his privacy was breached by two TDs – Sinn Féin’s Pearse Doherty, and the Social Democrats’ Catherine Murphy – who gave statements to the Dáil during a 2015 debate about the sale of Siteserv.Photo: Sam Boal/RollingNews.ie
