evidence: The 9th Circuit Court of Appeals overturned a lower court’s dismissal of a lawsuit challenging the constitutionality of a school district’s policy that required staff vaccination against COVID-19. Legal experts who follow vaccination and health law told PolitiFact that the appeals court didn’t rule on the vaccine mandate’s constitutionality. The appeals court ruling said the lower court might have incorrectly applied a U.S. Supreme Court precedent related to vaccination mandates.
