Ceann Comhairle Seán Ó Fearghaíl has said additional measures may have to be considered by the Oireachtas for deputies who abuse Dáil privilege and name individuals unfairly in the chamber.
In an interview with RTÉ News, he said the introduction of fines would be a crude instrument but it might be an effective one.
He added it would have to be agreed by the Committee on Procedure and Privileges, of which he is a member.
The Ceann Comhairle said it was important that matters of public interest are raised in the chamber but he said it should be done in a manner to avoid destroying an individual's reputation in circumstances where they are not in a position to defend themselves.

He also confirmed that the introduction of a 30-minute time limit for a quorum to be reached so Dáil business can proceed is being considered.
This comes after Dáil business was delayed for 40 minutes on 8 July as not enough deputies were present.
The Ceann Comhairle said the electorate, the public and the people that they serve expect politicians to be at their place of work on a normal working week.
He also said the Sub-Committee on Dáil Reform would review the changes made to the Dáil schedule before the summer break.
