The tribunal has adjourned and when it resumes will hear evidence to do with the granting of the second mobile phone licence to Esat Digifone.
Mr Michael Lowry, in his sixth day in the witness box, said he welcomed the investigation into the granting of the licence as he and his family had to suffer "the most horrific treatment" since the granting of the licence five years ago. The competition for the licence was conducted in a fair way, he said, but he would have "no peace" until the matter was investigated by the tribunal.
The tribunal has completed its evidence in relation to financial transactions involving Mr Lowry and which may be linked to Mr Denis O'Brien.
Mr Lowry said he never had any business dealings with Mr O'Brien or with anyone acting on his behalf. He had met Mr O'Brien socially on a number of occasions over the past few years, including at GAA, soccer and horse racing fixtures. He had also had lunch with him once in the Berkeley Court Hotel, in Dublin.
The men usually had "light- hearted" conversations, Mr Lowry said. Mr O'Brien usually asked him how he was and how he was getting on, as he recognised that he, Mr Lowry, was "under pressure".
However, he said, the two men never discussed the fact that Mr Lowry and Mr Aidan Phelan, Mr O'Brien's former financial adviser, were involved in British property dealings together.
Mr Lowry said it was clear Mr O'Brien knew he and Mr Phelan knew each other. "Once or twice he referred to things Aidan and I might have done."
Mr Lowry said he never had occasion to believe Mr O'Brien knew of his business dealings with Mr Phelan but presumed he had come up in conversations between Mr Phelan and Mr O'Brien.
Responding to his counsel, Mr Donal O'Donnell SC, Mr Lowry agreed that bank documentation indicated his Isle of Man account was an "instant access" account and not a fixed term one as indicated on another document produced to the tribunal.
