Georgia filed suit earlier this month asking that the court approve Republican-backed plans to redraw the state's legislative and congressional districts. But in that filing, the state asks that if the court rejects its redistricting plans, that it also rule the law that requires that approval to be unconstitutional.
Georgia is one of nine states that must get any change in election law, including district maps, pre-approved by either the Justice Department or the federal court in Washington. That preclearance is required by Section V of the Voting Rights Act, the landmark 1964 law passed in the wake of Jim Crow and voting laws aimed at limiting the ability of African-Americans to vote.
"The state of Georgia and its voters are being subjected to the continued extraordinary intrusion into its constitutional sovereignty through Section 5 and its outdated preclearance formula based upon discriminatory conditions that existed more than 47 years ago but have long since been remedied," the state says in its filing.
