Republican leaders in the Virginia House of Delegates have formally asked the U.S. Supreme Court to step in and block a lower court’s efforts to redraw the House map for the 2019 elections.

In a court filing released Thursday, House Speaker Kirk Cox, R-Colonial Heights, asked the Supreme Court to grant an emergency stay that would halt a lower court’s efforts to enact a new House map to fix 11 districts found to be racially gerrymandered. Republicans are appealing the ruling, and the Supreme Court has agreed to hear new arguments in the case early next year.
