Referendum result in Ireland


The following information explains how referendum results are collated.

The day after the poll, the ballot boxes are opened at a designated count centre in each constituency. The votes for and against the referendum proposal are counted and the local returning officer reports the result to the referendum returning officer. The results are published online as they come in.

When the results from all constituencies have been collated, the referendum returning officer draws up a provisional referendum certificate, stating the overall result of the voting. The certificate also states whether or not the proposed amendment has been approved by the people.

The provisional certificate is published in Iris Oifigiúil (the State Gazette).

If you wish to challenge the provisional certificate, you must present a petition to the High Court within 7 days of the publication of the provisional certificate. If no petition is presented to the High Court, the certificate becomes final.

Amending the Constitution

After a constitutional referendum, if the final certificate shows that the majority of the votes cast were in favour of the proposal to amend the Constitution, the President signs the Bill and the Constitution is then amended.
