Wisconsin Supreme Court Map Challenge Sparks Fierce Partisan Accusations and Dissent
The Wisconsin Supreme Court's liberal majority agreed on Thursday, June 11, 2026, to take up an appeal of a lawsuit aimed at redrawing the state's congressional voting districts1, expanding Wisconsin's years-long redistricting struggle.
The June 11 Order and Judicial Dissent
In an unsigned order released just before 5:00 PM, the court accepted an appeal filed by the national Democratic firm Elias Law Group. The appeal contests a lower-court dismissal of its lawsuit by a panel of three county judges earlier this year. The lawsuit contends that Wisconsin's current congressional map is unconstitutionally gerrymandered to guarantee a Republican majority. Under the existing map, Republicans hold six of the state's eight U.S. House seats, while Democrats hold only two.
The court's decision to accept the appeal sparked sharp, public dissents from the court's retiring conservative Justices Annette Ziegler and Rebecca Bradley, who accused the liberal majority of engaging in judicial activism and political bias.
Timeline and Impact on the 2026 and 2028 elections
While the Supreme Court's decision to hear the case represents a significant victory for national Democrats, the court's scheduled briefing timeline means that the current maps will remain in place for the 2026 midterms:
- 2026 Midterm Campaigns Unaffected: Congressional campaigns for Wisconsin's eight seats are already well underway under the existing map, and the state elections commission has already approved the candidate slates.
- Briefing Timeline Too Late for 2026: The Supreme Court's order establishes a standard appeals court timeline, with briefing schedules wrapping up in August and early September 2026. Legal experts note that this timeline is "definitely too late" to implement new maps for the November 2026 election.
- Looking Ahead to 2028: If the Supreme Court ultimately rules that the current congressional map violates the state constitution, any redrawn boundaries would take effect for the 2028 election cycle, potentially shifting the partisan balance of Wisconsin's congressional delegation.
This decision keeps Wisconsin at the center of the national, multi-state battle for control of the U.S. House of Representatives, as both major parties look past the immediate midterms to secure long-term electoral advantages.2
