According to an article in the Virginian Pilot, Republicans in Virginia’s General Assembly have asked the U.S. Supreme Court to delay a requirement that the state redraw legislative district lines by October, arguing that a lower court erred in finding the districts to be discriminatory against African Americans.

A three-judge panel of the U.S. District Court for the Eastern District of Virginia ruled on June 26 that the lines for 11 Virginia House of Delegates districts had been drawn with the purpose of concentrating black voters.

The 2-to-1 ruling was a victory for Democrats, who hope new district boundaries will help them re-take control of the House for the first time in nearly two decades. Last year’s elections wiped out a nearly 2-to-1 GOP advantage in the 100-seat House, leaving Republicans with a narrow 51-49 majority.

House Speaker Kirk Cox , a Republican from Colonial Heights, and other GOP leaders on Monday asked the Supreme Court to hear an appeal, arguing that the lower court reached incorrect conclusions.
