Overview
- The ACLU of Wisconsin, representing Voces de la Frontera, sued sheriffs in Walworth, Brown, Kenosha, Marathon and Sauk counties over their practice of honoring ICE detainers.
- The filing argues that holding someone up to 48 hours at ICE’s request amounts to a new arrest that Wisconsin law permits only with a judicial warrant.
- The justices accepted the case as an original action in a 4-3 split, with Annette Ziegler and Rebecca Bradley dissenting and Brian Hagedorn writing separately about procedure.
- An expedited timeline requires briefs within roughly two months, with oral arguments to be scheduled afterward and a possible decision by mid-2026.
- Sheriffs maintain their cooperation is lawful and are reviewing the order, while Republicans push a bill to withhold funds from counties that refuse detainers that could face a veto by Gov. Tony Evers.
