Georgia election officials say counties will review absentee ballots and count those previously rejected for missing or incorrect dates of birth.
The review was ordered by a federal judge Wednesday in response to a request included in a lawsuit brought by Stacey Abrams' campaign for governor.
Abrams trails former Secretary of State Brian Kemp by more than 50,000 votes.
Her campaign has disputed the results, and says she needs about 17,700 votes to force a Dec. 4 runoff.
Kemp's campaign contends that the results show he has an "insurmountable lead" in the race.
Counties have been ordered to count absentee ballots rejected "solely because of an error or omission in the date of birth" and recertify results if counts change. The deadline is Friday by 5 p.m.
