A three-judge panel for the United States District Court in Milwaukee recently wrapped up oral arguments in redistricting case. The lawsuit was filed by a number of citizens arguing that newly drawn electoral maps violate the U.S. Constitution.

Before oral arguments began, the court gave the attorneys for the Republican legislators a chance to redraw a portion of the maps. The legislators declined the request.

The lawsuit alleges that the new electoral maps are unconstitutional because they unnecessarily shift hundreds of thousands of voters into new districts. Electoral maps are redrawn every ten years based on updated census data.
