Finance Minister Michael Noonan has said he will not be advising the Oireachtas Banking Inquiry on how to conduct its investigations.
The 11-member committee, chaired by TD Ciarán Lynch, is meeting today to sign off on its terms of reference amid concerns that it may not be able to complete its work in time for the next election.
Speaking this morning, Minister Noonan was responding to a question about whether Jean Claude Trichet should speak to it.
Mr. Trichet, who was head of the ECB during Ireland's banking collapse, has previously said he will not appear before the Inquiry.
Members of the committee will gather for a private meeting today, but public hearings are not expected to begin for a number of months.
Minister Noonan says he hopes everyone involved will cooperate with the inquiry, but he will not be offering any advice on how it should be carried out.
"It's up to the chairman - I don't want to say anything to interfere with the inquiry," he said.
"They have terms of reference, they've got advice now from a group of specialists and (can) get on with the jobs now and make their own decisions.
"I'm certainly not going to be advising them either way - but obviously for an efficient inquiry, they need to hear from everybody who was directly involved."
