UAW President Ray Curry is narrowly trailing reform candidate Shawn Fain in his bid for reelection after most votes have been counted, and the race now depends on about 1,600 challenged ballots.
Fain leads Curry by 645 votes in the runoff election, according to the federally appointed monitor overseeing the voting process.
The race will determine who will lead the union through high-stakes contract negotiations with the Detroit 3 this fall. Already, six reform-minded challengers have won leadership spots on the union's 14-member International Executive Board.
The monitor's office said in a statement that it was working closely with the UAW and the election vendor to review the challenged ballots and verify the eligibility of the members who cast them.
"Once the eligibility status of enough challenged ballots has been resolved (subject to further observer challenge), the vote count will continue at a time and place to be determined," the monitor said. "Barring unforeseen delays in clearing enough challenged ballots, we expect to reconvene with the observers on March 9, 2023, at a place to be determined in the Detroit metropolitan area."
The vote count had been taking place in Dayton, Ohio.
