In Resurrection School v. Hertel, (6th Cir., Aug. 23, 2021), the U.S. 6th Circuit Court of Appeals, in a 2-1 decision, rejected free exercise, equal protection and due process challenges to Michigan's previous COVID-19 mask order for schools. The court affirmed the denial of a preliminary injunction sought by a Catholic elementary school. All 3 judges agreed that the case is not moot because the mask requirement might be re-imposed. The majority, however, held:
[T]he district court ... correctly concluded that because the requirement to wear a facial covering applied to students in grades K–5 at both religious and non-religious schools, it was neutral and of general applicability.
Judge Siler filed an opinion dissenting in part. Detroit News, reporting on the decision, says that the school will seek en banc review.
