This week, the Wisconsin Supreme Court will hear oral arguments in a pair of cases that present two questions at the core of an ongoing struggle between some of the most powerful forces in the state.
In the first, the seven justices will hear an appeal of a lower court ruling that could hamper the Wisconsin Department of Natural Resources’ ability to enforce the state’s “Spills Law.” Enacted in 1978, the law requires people or companies discharging a hazardous substance “to restore the environment to the extent practicable and minimize the harmful effects from the discharge to the air, lands or waters of this state.”
The lawsuit, which the court will hear on Tuesday morning, was filed by Wisconsin Manufacturers & Commerce in 2021. It argued that the DNR could not require people to test for so-called “forever chemicals” contamination — and require remediation if they’re present — because the agency hadn’t gone through the formal process of designating the chemicals, known as PFAS, as “hazardous substances.” A circuit court judge and the District 2 Court of Appeals agreed, so the state appealed to the state Supreme Court.
The agency maintains that a court loss would strip its authority to compel polluters to clean up chemicals and provide emergency water under the Spills Law, cutting off residents on PFAS-contaminated French Island who have been receiving water since 2021.
