On Tuesday, November 30, 2021, the PA Supreme Court reinstated the mandate imposed by the PA Department of Health requiring students and school staff to wear masks in the K-12 school environment. The reinstatement is in effect at least until the court hears arguments on December 8, 2021.

In early November, despite Governor Wolf’s decision to allow school districts to modify or end the mask mandate for K-12 schools on January 17, 2022, a Commonwealth Court judge ordered the mandate to be lifted on December 4, 2021. Governor Wolf appealed that decision, sending the matter to the PA Supreme Court.
