The former chairman of the Revenue Commissioners, Séamus Paircéir (right), who featured at the Moriarty tribunal this week, retired from the public sector in September 1987.
Mr Paircéir was one of a number of senior civil servants who, after retirement, went on to hold a number of high-profile positions in both the public and private sectors.
During various stages in the 1990s he was chairman of the Custom House Docks Development Authority, chairman of the committee to advise on the development of the IFSC and a consultant to the IDA in connection with the promotion of the financial services centre.
However, it was as a director of the private-sector company United Property Holdings that his name became prominent.
United Property Holdings was the company that bought the former Johnston Mooney and O'Brien site at Ballsbridge. The company later sold it on and eventually the property ended up in the ownership of Telecom Éireann, then still in State hands.
The sale and the amount paid for the property later became a matter of controversy known as the Telecom affair. During the course of an RTÉ radio interview in September 1991, Mr Haughey said he thought it would be "prudent" if Mr Paircéir and a number of other parties were to "step aside" pending an investigation into dealings concerning the Ballsbridge site.
Mr Paircéir was in his car driving to Belfast when he heard the interview and was "absolutely shocked". He subsequently resigned as chairman of the Custom House Docks Development Authority and said there was no provision for him to step aside temporarily.
Mr Haughey, in the interview, had said that Mr Paircéir was "an impeccable man with a good fine record in public service".
In 1999 Mr Paircéir was appointed as an independent exams appeal commissioner by the Department of Education.
