Wis. 2012): Plaintiffs filed a federal lawsuit challenging the Legislature’s enacted congressional plan as violating the 14th Amendment’s Equal Protection Clause on the grounds that districts were not compact and failed to preserve communities of interest, and that the plan was a partisan gerrymander in violation of the 1st Amendment. On March 22, 2012, the district court ruled that the congressional plan did not violate the one person, one vote constitutional principle and rejected the partisan gerrymandering claim due to there being no workable standard to evaluate it.

      • Baldus v. Members of Wis. Gov’t Accountability Bd., 849 F.Supp.2d 840 (E.D. Wis. 2012): Several different groups of plaintiffs filed federal lawsuits challenging the Legislature’s enacted legislative plans as violating the state and federal constitutions and federal law on a number of grounds, including a failure to preserve municipal boundaries and communities of interest, non-compactness, malapportionment, partisan gerrymandering, racial gerrymandering, and vote dilution under Section 2 of the Voting Rights Act. On March 22, 2012, the district court struck down two of the state House districts as violating Section 2 of the Voting Rights Act and ordered they be redrawn, but rejected all other claims.
      • Gill v. Whitford, 138 S.Ct. 1916 (2018): A group of Wisconsin voters filed a federal lawsuit challenging the Legislature’s enacted legislative plan as a partisan gerrymander in violation of the 1st Amendment’s Right of Association and the 14th Amendment’s Equal Protection Clause. The district court had ruled in favor of the plaintiffs and struck down the plan as violating the 1st Amendment and the 14th Amendment’s Equal Protection Clause, but on June 18, 2018, the U.S. Supreme Court vacated and remanded the case for further proceedings to allow the plaintiffs an opportunity to prove the requisite concrete and particularized injuries to establish standing.
        • Whitford v. Gill, No. 3:15-cv-421 (W.D. Wis. July 2, 2019): On July 2, 2019, the district court, on remand from the U.S. Supreme Court, dismissed the lawsuit in light of Rucho v. Common Cause’s ruling that partisan gerrymandering claims were nonjusticiable political questions beyond the reach of federal courts.

Wisconsin Elections Bd., 639 N.W.2d 537 (Wis. 2002): After the split-control Legislature failed to pass a legislative redistricting plan, plaintiffs petitioned the state courts to declare the existing districts unconstitutionally malapportioned and to enact new, properly apportioned plans. On February 12, 2002, the Wisconsin Supreme Court rejected the petition, citing the collateral lawsuit in federal court seeking the same relief and stating it would give the Legislature an opportunity to pass a plan through the ordinary lawmaking process.
      • Baumgart v. Wendelberger, No. 01-C-0121 (E.D. Wis. May 30, 2002): After the split-control Legislature failed to pass a legislative redistricting plan, plaintiffs petitioned the federal courts to declare the existing districts unconstitutionally malapportioned and to order the adoption of a new, lawful plan. On May 30, 2002, the district court ruled that the existing legislative districts were unconstitutional and adopted its own state House and Senate redistricting plan.
