A group opposed to the Lisbon Treaty is to deliver leaflets outlining its position to over 1.4 million homes in Ireland over the next two months.
Libertas, a think-tank opposed to the treaty, argues that if the Lisbon Treaty is passed, there will be no need for the EU to consult the Irish people on future extensions of its remit.
The group will privately fund the distribution of the leaflets, at an estimated cost of €180,000.
Speaking in Dublin this afternoon, the founder of Libertas, businessman Declan Ganley said the group was "forced" into the move due to a refusal on the Government's part to spend State money to inform people "in an unbiased manner".
Earlier this month, the group lodged a formal complaint to the Standards in Public Office Commission (Sipo) requesting it to launch an investigation into a website established by the Department of Foreign Affairs it claims breaches the ruling of the Supreme Court in the Patricia McKenna case from 1995.
Libertas contends that the website uses public monies to promote the 'Yes' side of the debate.
Mr Ganley said it was "a disgrace" that the referendum commission "has essentially been gagged by the Government."
He said the Government was hoping that if people don't get any chance to read the arguments against the treaty, they will be "bullied" into believing that somehow rejecting this treaty would be harmful to Ireland and Europe, which he said was "nonsense."
Mr Ganley accused the Green Party and its leader John Gormley of making a u-turn on the treaty.
"He opposed the EU Constitution, and yet he supports this Treaty. Can he tell us what it is in this Treaty that has made him conduct this 360-degree turn? Can he honestly look anybody in the eye and say that in his heart, he supports this document?"
No date has been decided for the referendum but there is speculation that the Taoiseach favours a date in late May.
