Sinn Féin has called on the government to commit to holding a referendum on the planned EU fiscal treaty.
The party said the coalition is trying to avoid holding a vote on the matter and said it would consider all measures, including taking legal action, to ensure the issue is put to the public.
The Taoiseach has said no decision on a referendum can be made until the final draft of the pact is agreed.
Today Sinn Féin launched its policy paper on the eurozone crisis.
The party's deputy leader Mary Lou McDonald said there is a democratic imperative to hold a referendum on the agreement.
Those comments were echoed by the party leader Gerry Adams, who said they would seek legal advice if the government decides no vote is necessary.
The party said the agreement currently being negotiated will not solve the eurozone crisis and will in fact make matters worse.
They described it as an “austerity treaty” that is bad for Ireland and bad for Europe.
The party is arguing for increasing the lending capacity of the European Investment Back to stimulate growth and jobs.
It is also calling for ending the obligation on the state to pay the Anglo Irish Bank promissory note and cleansing the European banking system through a new round of rigorous stress tests.
