The High Court has reserved its judgment in the legal challenge being taken by the Taoiseach against aspects of the Mahon Tribunal's inquiries.
Two of the three issues being challenged by Mr Ahern have effectively been resolved.
The court heard this morning that the tribunal has handed over 115 pages of documents to Mr Ahern's legal team.
The documents contain bank data and computer records relating to the tribunal's suggestions that bank lodgements made in 1994 were in sterling and in dollars.
Mr Ahern's lawyers said that after this concession they did not need to cross-examine witnesses on the documents and the issue was resolved.
The court has also heard that the tribunal no longer wishes to question Mr Ahern about statements he made in the Dáil in 2006.
The tribunal accepts that these statements are privileged under the Constitution, and Mr Ahern cannot be questioned about them by any other body other than the Dáil itself.
The court was told the tribunal would not seek to question the veracity, propriety or motivation behind the statements.
However, the tribunal says it is not prohibited from referring to the fact that such statements were made in its report, or during the course of questioning the Taoiseach about statements made outside the house.
The main issue now to be decided by the three-judge divisional High Court is the issue of whether documents relating to advice given by Mr Ahern's banking expert, Paddy Stronge, are privileged.
The tribunal is seeking 150 documents from Mr Ahern's legal team in relation to their communication.
It says Mr Ahern cannot claim the same privilege he would claim in a court case because the tribunal is a fact-finding body, which is not involved in the administration of justice.
It also says because a lot of the documents refer to communications between the Taoiseach's legal team and Mr Stronge, who is not their client, they are not privileged.
High Court President Mr Justice Richard Johnson said the three judges would review all the contested documents and they would give their decision at a later date.
