A panel of federal judges says Michigan's congressional and state legislative maps are unconstitutional.
The Michigan League of Women Voters and a group of Democrats filed a lawsuit in 2017 alleging that a number of districts were drawn with excessive partisanship favoring Republicans.
The judges agreed Thursday, ruling that 27 of the 34 challenged districts violated the plaintiffs' rights guaranteed under the First and 14th Amendments "by diluting the weight of their votes." They also said all 34 violated the plaintiffs' First Amendment right to association.
Michigan's Republican-controlled legislature now has until Aug. 1 to redraw new maps and get Democratic Gov. Gretchen Whitmer to sign them into law for the 2020 elections.
If they fail to meet the deadline, the judges said the court will redraw the maps itself.
The new maps will only be used for the 2020 election cycle, though. That's because Michigan voters have already approved the creation of an independent commission to redraw the district lines for the 2022 election using data from the 2020 census.
