On May 13, 2020 the Wisconsin Supreme Court struck down Governor Tony Ever’s Emergency Orders saying “We further conclude that Palm’s order confining all people to their homes, forbidding travel and closing businesses exceeded the statutory authority of Wis. Stat. § 252.02, upon which Palm claims to rely.  By the Court.—Palm’s Emergency Order 28 is declared unlawful, invalid, and unenforceable”  Please note the Wisconsin Supreme Court specifically stated that their decision does not apply to Section 4.a of Emergency Order 28 which says “Public and private K-12 schools shall remain closed for pupil instruction and extracurricular activities for the remainder of the 2019-2020 school year.” which remains in effect. The Wisconsin Supreme Court ruling does not necessarily invalidate any municipal or county quarantine rules.
