The Penn State Law Federalist Society sponsored a conversation discuss the constitutionality of vaccine mandates, religious exemptions and their uses, and a variety of other topics with Professor Larry Backer and Mr. Eric Treene.  The object of discussion was generally the emerging framework of exemptions under Constitutional and statutory Free Exercise principles as they might be applied to the authority of the US military to mandate vaccination. The specific discussion centers on Austin v. U.S. Navy Seals (2022) now hovering within the Supreme Court's shadow docket.
