A legal action taken by convicted murderer Graham Dwyer against the State is due to begin this morning.
He was convicted in 2015 for the murder of Elaine O’Hara, in what was one of the biggest trials ever held in Ireland.
The jury found Dwyer, with an address in Foxrock in Dublin, had stabbed her to death for his own sexual gratification.
Mobile phone records which detailed the communications between Dwyer and O’Hara played a vital role in the trial and placed them both at the scene.
However, Dwyer claims his right to privacy was breached because of laws surrounding how such data is retained.
