UC Davis Law professor Vikram David Amar, professor emeritus Alan Brownstein, and Illinois Law professor Jason Mazzone analyze the Fifth Circuit’s decision in Umphress v. Hall, a case involving a Texas judge’s federal lawsuit seeking protection from disciplinary action for refusing to perform same-sex marriages based on religious beliefs. In this second of a two-part series of columns on that case, the authors argue that judges who perform marriages act as state actors and therefore must adhere to the constitutional mandates of equality and due process. They further explain that allowing religious-based discrimination in such roles undermines the core principles established in Obergefell v. Hodges and related equal protection jurisprudence.
