COLUMBIA, S.C. (AP) – South Carolina’s redrawn state house and congressional maps were allowed to stand Monday, as the U.S. Supreme Court summarily affirmed a federal court’s ruling that the state’s new lines are fair and don’t discriminate against racial minorities.

Six black voters from Florence, Sumter, Georgetown, Berkeley, Darlington and Charleston counties sued Gov. Nikki Haley, the Legislature and other state officials earlier this year. They claimed the GOP-dominated state Legislature drew lines that segregate white and black voters into election districts and pack black voters into one congressional district, calling it “voting apartheid.”
