Utah Republicans filed a lawsuit challenging a state judge’s selected redistricting map that would give Democrats a greater chance of winning a U.S. House seat in November.

The lawsuit, filed on Monday in a federal court, challenges Utah judge Diana M. Gibson’s decision to reject the Republican legislature-drawn map in favor of a map drawn by plaintiffs who argued against the GOP plan. The court-selected map will include a new Salt Lake County district that is expected to favor Democrats by over 17 points. The previous map gave Republicans wins in all four U.S. House districts in the state.
