Referendums
As Ireland’s independent electoral commission, it is our responsibility to prepare impartial and unbiased information about referendum proposals and make that information available to the public.
We prepare impartial statements containing a general explanation of the subject matter of the proposal for the referendum concerned and distribute those statements through an information booklet, television ads, radio, newspapers, social media and other forms of media to bring them to the attention of the public. We are committed to ensuring that all information we provide is accessible for those with a disability.
What is a referendum?
In Ireland, there are two kinds of referendum that can take place – a constitutional referendum and an ordinary referendum.
The Constitution (Bunreacht na hÉireann) is the fundamental legal document that sets out how Ireland should be governed.
The Constitution can only be amended if the proposed change has been approved by the people of Ireland in a constitutional referendum. This gives the people of Ireland the chance to decide whether or not the wording of the Constitution will change.
To hold a Constitutional Referendum, a Bill must first be introduced in the Dáil, setting out the wording of the proposed amendment. If both the Dáil and the Seanad pass the Bill, the Minister for Housing, Local Government and Heritage makes an order specifying the polling day for the referendum.
All Irish citizens who are on the Register of Electors, the Postal Voters List or the Special Voters List can vote in a referendum.
If the majority of the votes are in favour of the proposal to amend the Constitution, and no petition challenging the result is presented to the High Court within seven days of its publication, then the President of Ireland signs the Bill and the Constitution is amended.
If the majority of votes are cast against the proposal to amend the Constitution, then there is no change and the Constitution remains as it was before the referendum vote.
