The Dáil Committee on Members' Interests will meet today to consider a complaint about Fianna Fáil TDs voting for colleagues who were outside of the chamber.
The committee, which is due to meet in private this afternoon, will first have to consider if the complaint from Fine Gael TD Noel Rock is admissible and then, if it is, what action to take.
The complaint was made after it emerged that Fianna Fáil's Niall Collins voted six times for his colleague Timmy Dooley who had left the chamber.
The two TDs, along with party colleagues Lisa Chambers and Barry Cowen, subsequently apologised to the Dáil for voting irregularities.
Mr Rock's complaint relates to all four Fianna Fáil TDs.
RTÉ News understands that the default position is for a hearing into such a complaint to be held in private however, under the relevant legislation, committee members can vote to hold it in public.
Questions have been raised as to whether the committee should seek phone records, or CCTV footage from in and around Leinster House, to assist in their deliberations.
The committee is chaired by Fine Gael's Hildegarde Naughton and members include Eamon Scanlon of Fianna Fáil, Jonathan O'Brien of Sinn Féin, Willie Penrose of Labour, and the Independent deputy Mattie McGrath.
It is open to the committee to recommend that the deputies found to be at fault are suspended from the House for a period of time.
However, Ceann Comhairle Seán Ó Fearghaíl, who described the voting controversy as "stark and unpalatable", has said any sanctions could only be imposed if passed by a Dáil vote.
Mr Dooley has said that he never asked Mr Collins to vote on his behalf. Mr Collins said he believed that Mr Dooley was at the back of the Dáil chamber when he voted for him.
Fianna Fáil's Ms Chambers said she accidentally voted on one occasion for the party's deputy leader, Dara Calleary, who was out of the chamber conducting a radio interview.
She said it was an accident, but wholly accepted she should have informed the Dáil teller of the error.
