The Oireachtas banking inquiry officially gets underway this morning.
The 11 members will hold a private meeting in Leinster House to begin working on the terms of reference for the inquiry.
There have been concerns that the committee may be hampered by the row over the membership, and Government moves to guarantee a majority.
Fianna Fáil's Michael McGrath is one of the 11 members, and said he hopes the committee can put the recent rows behind it.
"That will become pretty clear very quickly – as to whether or not people are going into this process with an independent mind," he said.
"I think the most difficult discussion we are going to have … is likely to be around the terms of reference."
He said the Government's commitment that there will be no interference will be tested by that discussion. The Government, for its part, has said it will not apply to the party whip to committee votes.
Sinn Féin's Pearse Doherty said it was unlikely that things would progress much before the summer recess because of the delays in recent weeks.
