The Junior Finance Minister, Brian Hayes, has said the Government is working to claw back salaries and pensions paid to top banking executives.
The issue was top of the agenda at a Dáil discussion for a third day today, after it emerged that six former Anglo executives, now working in IBRC, are earning in excess of €500,000.
Earlier, the Tanaiste Eamon Gilmore said there is the political will to tackle the high salaries within the banking sector.
However, Minister Hayes said the Government is bound by the law.
Mr Hayes said: "We don't have a situation in Irish Constitutional law where we can retrospectively introduce legislation and effectively change the terms and conditions.
"We are going to look at this again, I know the Minister for Finance, who was before a committee today, has said he has held discussions with the chairman of IBRC.
"The Taoiseach has already spoken very clearly about the responsibility of those senior bankers and we will see what further can be done."
