The Labor Party is to draw up legislation to ban the payment of ministerial pensions to serving politicians, RTE reports.
Labor leader Eamon Gilmore said its legal advice was that there was no constitutional impediment to such legislation.
He said while the withdrawal of pensions might fall foul of the constitution, a change to the point when they were paid would not.
He said Labor's legal advisers were looking at the question of whether private members' legislation could deal with a financial issue.
Once that is cleared up, he added, the legislation will be published.
Gilmore said he had not discussed the pension issue with party colleague Ruairi Quinn, who today announced he was giving up his ministerial pension.
Waterford Labor TD Brian O'Shea has announced he will also give up his ministerial pension.
O'Shea, a former junior minister, received €7,716.47 last year.
All Labor politicians have now surrendered their pension in one form or another.
O'Shea's decision brings to four the number TDs who have announced they are to give up their ministerial pensions after the decision last night by European Commissioner Máire Geoghegan-Quinn, a former Fianna Fail TD, to forego her Dáil and ministerial pensions.
Labor TD Emmet Stagg has said he will give up his ministerial pension as has Fine Gael TD Bernard Allen.
Stagg was appointed Minister of State at the Department of Transport, Energy and Communications in 1995 and Allen was Minister of State for Sport during the Rainbow Coalition.
Quinn, who is a former Minister for Finance, said he had made his decision because of the poor state of the public finances and because economic conditions in the country had not improved since the original pension reductions were made. Last year, he received a ministerial pension of €41,656.04.
