Alabama’s attorney general filed a lawsuit Thursday asking a federal court to approve a redistricting plan for his Legislature without requiring the plan to go through the U.S. Justice Department for approval to make sure it doesn’t discriminate against minority voters. The lawsuit seeks a declaratory judgment from a three-judge panel of U.S. District Court in Washington finding that the plan approved by the Alabama Legislature during a special session in May does not deny or abridge the right to vote based on race or color. Joy Patterson, a spokeswoman for the Alabama Attorney General’s office, said the state has the option of seeking pre-clearance from the Justice Department or asking for a three-judge panel to do it. She said the attorney general’s office filed a similar suit last year for its new Congressional and state school board districts. But the Justice Department ended up preclearing those districts anyway.
