Fulton County's Board of Registration and Elections will vote for the second time Monday morning on whether to shut down six polling locations.
The board approved closing the polling locations, which are in predominantly black neighborhoods, last month.
Elections officials said not enough people use those locations to justify keeping them open.
The ACLU sued saying the board didn't give the public enough notice of the proposed changes before taking a vote.
Any permanent changes to polling locations must be approved by county commissioners.
The elections board meets at 10 a.m. Monday.
