An electoral register blunder which saw the wrong polling information sent to 35,000 people has been rectified.
Dublin City Council admitted the mistake which saw a number of polling cards being sent out addressed to people who were dead.
It said every affected voter has been sent a letter with the correct details, including where to cast their ballot.
"All voters can rest assured that they will not be denied a vote as a result of this error," the council said.
Regardless of the information that was sent, all voters are entitled to cast their ballot if their name is on the electoral register and they can prove who they are.
The council has sent letters to voters whose original polling cards directed them to the wrong station advising them where they should cast their vote.
Letters have also been sent to voters who are new to the electoral register or who moved house recently with details of their electoral number and where to go to vote.
Polling stations on the referendums on whether to abolish the Seanad and establish a court of appeal open on Friday morning and the results of the votes are expected early on Saturday afternoon.
The council discovered its mistakes on Monday.
It revealed that polling cards were generated by out of date records that had not been updated with additions to the voters' register.
