Wisconsin House map suits slip past 2026

Two lawsuits challenging Wisconsin’s congressional districts are unlikely to be resolved before the 2026 midterms, judges and schedules indicated during Dec. 12 hearings in Madison. One three-judge panel set a prospective trial date of April 5, 2027 if the case proceeds, while plaintiffs in a separate case urged a ruling by the Wisconsin Elections Commission’s March 1, 2026 map deadline; defendants argue rushing for 2026 would be unfair. The Wisconsin Supreme Court last month directed that such redistricting suits be first heard by three-judge panels under a 2011 law.
