Gay couples hoping to get married will have to wait even longer for it to become legal.
Two men who've already twice appealed May's yes vote are now taking their case to the Supreme Court.
Gerry Walshe, an electrician from Co. Clare, and Maurice J Lyons, a gardener from Kilkenny, believe the views of those opposed to same-sex marriage were not taken into account by government in the lead up to May's referendum.
The High Court and the Appeals Court have both already rejected the men's challenges.
Both men have been representing themselves in court, and claim the referendum process was not fair or impartial. They believe the yes vote would introduce 'uncertainty' into the Constitution, and that changing the law 'conflicts with Ireland's Christian ethos'.
The same-sex marriage was passed by more than 62% on May 22, with the percentages voting yes much higher in Dublin.
The Supreme Court doesn't have to hold a hearing to deal with applications made to it, so it's a matter of paperwork but there is no set time frame on when the case will be dealt with, throwing some people's wedding plans into doubt.
Following May's yes vote, the Justice Minister, Frances Fitzgerald, said she hoped laws allowing same sex couples to tie the knot would be in force by summer.
It's not known how long this appeal to the Supreme Court will delay gay marriage being made legal by.
