Some £1 million in proceeds from a land deal involving builders Mr Tom Brennan and Mr Joe McGowan could not be accounted for at the tribunal yesterday.
Mr Brennan said he received £100,000 from the deal, the sale in 1985 of three acres at Bellevue Avenue, Donnybrook, but he did not know what happened to the remainder of the money.
Neither Mr McGowan nor auctioneer Mr John Finnegan received any of the £1.1 million, the tribunal also heard.
Mr Pat Hanratty SC, for the tribunal, said the £1.1 million did not just "go astray". He put it to Mr Brennan that he knew where the money went, but was refusing to tell the tribunal.
Mr Brennan denied this and said that he, too, wanted to "get to the bottom of this". He would tell the tribunal today what happened to £1 million and would explain where he got his £100,000.
The Donnybrook lands were transferred, the tribunal was told, to Farrell Homes Ltd for two policies, described as "Capital Redemption Policies" in the sum of £920,000 and £180,000, totalling £1.1 million.
These policies were exchanged for bank drafts, which were subsequently transferred to the Royal Bank of Scotland in the Isle of Man, the tribunal was told. Mr Hanratty said he assumed the money ended up in the British Virgin Islands.
Earlier yesterday Mr Hanratty said information from a Brennan and McGowan company in Liechtenstein which arrived in Dublin yesterday contained a "substantial deficit" in the documents ordered.
This had "significant implications for the question of complying with the order" made by the tribunal for Mr Brennan to produce all relevant documents by next Tuesday. If he does not comply, Mr Justice Flood will refer the matter to the High Court.
Information received from Liechtenstein concerned a foundation owned by Mr Brennan, St Anthony's, which was a family fund.
Mr Martin Hayden SC, for Mr Brennan, said additional documents had been ordered, but it might be difficult to produce all the files by Tuesday.
Mr Hanratty said they were "covered by the order".
Mr Justice Flood said he would take "no nonsense". He said: "The order is the order and must be obeyed".
Mr Brennan also said yesterday he would have no objection to Mr Martin Bullock, administrator of his offshore trust in the Isle of Man, being asked to appear at the tribunal.
