A federal court review of Florida's new election law will extend into July, just a month before the Aug. 14 primary.
A Department of State spokesman on Monday said Florida is prepared to use two election laws if the U.S. District Court in Washington, D.C., doesn't rule before the primary.
A judge last week issued a schedule that doesn't require final briefs to be filed until July 9.
The court is reviewing provisions that restrict voter registration drives, reduce early voting days and require provisional ballots for voters who change out-of-county addresses on Election Day.
Opponents say those provisions discriminate against minorities, the elderly and young people.
They cannot be implemented in five Florida counties covered by the federal Voting Rights Act until they get court approval.
