The businessman Denis O'Brien has told the Moriarty Tribunal that some of his business rivals have tried to damage him because of the tribunal's investigations.
He said he wanted the Tribunal to note that its workings in Dublin Castle had impacted negatively on him, his family and his international business dealings.
Mr O'Brien again stated that he had never given any money or benefit in kind to the former Minister Michael Lowry, and said that Esat won the State's second mobile phone licence in 1995 in a fair competition.
Mr O'Brien today completed giving his evidence to the tribunal in the module examining issues surrounding his business dealings involving Doncaster Rovers Football Club.
He said all evidence heard by the tribunal showed Mr Lowry had 'no hand, act or part' in the Doncaster Rovers deal.
He said the final report of the tribunal, whenever it is completed, would not get the same media attention as the opening statements.
Mr O'Brien said when he explained to people overseas that the tribunal is investigating the awarding of a mobile phone licence 12 years ago 'they are amazed at how justice is administered in Ireland'.
He said he was most upset by the conduct of the tribunal when his daughter was born six years ago, and the tribunal sought his wife's medical records.
Mr O'Brien said certain investigations by the Tribunal were a waste of taxpayers money.
