The chairman of the Centre for Public Inquiry (CPI), retired High Court judge Feargus Flood, has said that the centre has ceased its work and would not be publishing any more reports.
Mr Justice Flood said that the board would be meeting one last time to sign documents and cheques relating to the winding- up of all activities. He indicated that he and other members of the board had no plans to re-establish the centre.
Last December Atlantic Philanthropies, the charity of American billionaire Chuck Feeney, withdrew funding from the centre following allegations about the centre's executive director, Frank Connolly, by Minister for Justice Michael McDowell.
The centre had been expected to publish at least one more report, on property deals in the Dublin docklands area, but there will now be no further publications.
The future of the centre came into question last December, when Mr McDowell claimed in a written Dáil reply that Mr Connolly had travelled to Colombia in 2001 under a false passport with an IRA leader with the aim of passing on technical know- how to the Farc guerrillas, in return for money for the IRA.
Mr Connolly has consistently denied the claim.
He was interviewed by gardaí in 2002 who asked him about the alleged trip. In 2003, the Director of Public Prosecutions decided not to bring any charges against Mr Connolly.
Last September Mr McDowell met Mr Feeney, during which he outlined the allegations against Mr Connolly, a former journalist.
Yesterday Mr Justice Flood told The Irish Times there had been "no alternative there for us" other than to close the centre, once Atlantic Philanthropies, which had originally committed nearly €5 million to the centre, decided to pull the funding.
The work on Dublin docklands had been at an early stage, Mr Flood said.
He said the CPI board was anxious to ensure that no individual would be left out of pocket by the centre's closure.
Yesterday's Sunday Times reported that the Centre for Public Inquiry had received legal letters from one property development company warning that the directors of the CPI would be held personally liable if the centre published a report that was defamatory of it.
The CPI published two reports during its operation, one on the sale of State land close to Trim Castle and another into the Corrib gas pipeline.
