Fianna Fáil has called for a new structure to be established in the Oireachtas to oversee the work of committees.
The party's spokesperson on Communications Timmy Dooley said this should be similar to the Standards in Public Office Commission and would be made up of former TDs.
Speaking after the Supreme Court found last week that the Public Accounts Committee had acted outside its remit in its questioning of former Rehab boss Angela Kerins, Mr Dooley said it is difficult for members who currently serve in the Dáil to set the standards for themselves.
He told RTÉ's The Week in Politics that there is a need for an outside body that could draw on the experience of former Oireachtas members "who could look at it in the cold light of day and with the benefit of experience."
Speaking on the same programme, Minister for Health Simon Harris said the suggestion was a "good idea."
"I think there is an opportunity for former members and former officials of the house to get together in an advisory capacity and draw up a new set of rules and procedures that would assist the Dáil" - @timmydooley TD. #rtetwip #rtepolitics pic.twitter.com/KLuUZRy9eu— The Week in Politics (@rtetwip) March 3, 2019
