Tipperary voters will be going to the polls on Saturday with the rest of the country.
Last night, Planning and Local Government Minister Eoghan Murphy signed a special electoral order allowing it to proceed as planned.
The sudden death of Independent candidate Marese Skehan had initially led to the likely postponement of the vote in Tipperary.
However, Minister Murphy's department confirmed the vote would now proceed following legal advice from the Attorney General.
In a statement, the department said: "The Minister is satisfied that this order is necessary to address a special difficulty that occurred this week in relation to the holding of an election in the constituency of Tipperary.
"The difficulty relates to the impossibility of completing a fresh election in that constituency in accordance with section 62 of the Electoral Act 1992 and within the 30 day time limit set out in article 16.3.2 of the Constitution, following the death of a candidate.
"Minister Murphy expresses his sincere sympathies to the family and friends of Marese Skehan on her very sad passing."
Returning officer for the Tipperary constituency, James Seymour, said the decision means Ms Skehan will still be on the ballot paper.
He explained: "We will be getting further directions from the department - from the franchise section - during the course of Thursday, so once we hear from them we'll be much clearer what we'll have to do.
"My understanding at this point of time is that we'll count the votes of all the candidates that are on the ballot paper in the normal order."
He also noted that postal votes that have already been submitted will remain valid for the poll.
