Polling booths have opened in two referendums.
We're being asked to decide on the abolition of the Seanad and the establishment of a court of appeal.
The counting of the votes will take place tomorrow.
3.1 milion voters around the country have until 10 o clock tonight to cast their ballot on the 32nd and 33rd amendments to the constitution.
A white ballot paper will be given asking voters to say yes or no to the abolition of the Seanad, while a Green paper will ask if voters want to set up a court of appeal.
While a polling card is not necessary to vote, acceptable proof of identity may be.
