Andrew David Hurwitz (born October 1, 1947) is a Senior United States circuit judge of the United States Court of Appeals for the Ninth Circuit. He served as a justice of the Arizona Supreme Court from 2003 to 2012. Education and clerkships Hurwitz graduated cum laude and Phi Beta Kappa from Princeton University in 1968 with an Artium Baccalaureus degree in Public and International Affairs. He earned his Juris Doctor from Yale Law School in 1972, where he served as a member of the Board of Editors and the Note and Comment Editor of the Yale Law Journal. After law school, he clerked for Judge Jon O.
