MADISON, Wis. – The Wisconsin Supreme Court on Wednesday blocked Democratic Gov. Tony Evers from issuing any new public health emergency orders to mandate face masks without the approval of the Republican-controlled state legislature.

In a 4-3 decision, conservative justices in the majority declared the statewide mask mandate invalid and ruled Evers exceeded his authority in issuing multiple emergency declarations over the ongoing COVID-19 pandemic. Evers used the emergency orders to require face coverings be worn indoors statewide after lawmakers opted not to.
