The Flood tribunal still has not seen any documents proving that a company, part-owned by the builder Mr Tom Brennan, ever received payment for a house sold to the former Fianna Fail minister, Mr Ray Burke.
Mr Pat Hanratty SC, for the tribunal, said it was one of 27 matters the tribunal would be revisiting in its questioning of Mr Brennan next Tuesday.
Mr Brennan said he had sought evidence of the transaction from National Irish Bank but found the documents held by the bank only went back as far as 1985. The house in Swords, Co Dublin, was built in the early 1970s.
Previous evidence by a solicitor, Mr Esmonde Reilly, told the tribunal that no money changed hands in the transaction.
Mr Brennan and Mr Burke have told the tribunal Mr Burke paid £15,000 for the house and an acre of land. A director of the company in question, Oak Park Developments, said Mr Burke paid the sum in three instalments while Mr Burke's counsel said the house was paid for in one tranche. Last year Mr Burke's house was sold for a reported £3 million.
An examination of documents from 1971 to 1978 sent to the Revenue Commissioners during a company investigation did not yield information about the payment, Mr Hanratty said.
The tribunal had been seeking documents held by Mr Martin Bullock, administrator of Mr Brennan's offshore trust in the Isle of Man. Mr Bullock said he would not travel to Dublin but, if it wished, the tribunal could travel to the Isle of Man to interview him. The possibility of travelling there was raised by Mr Martin Hayden SC, for Mr Brennan yesterday. The matter would be returned to on Tuesday.
