In the U.S. Court of Appeals for the Ninth Circuit, which includes nine western states, Ben is the author of Thomson Reuters’s 1200-page treatise Federal Appellate Practice: Ninth Circuit, and served as the court-appointed chair of the Appellate Lawyer Representatives to the Ninth Circuit Judicial Conference. He previously served as a law clerk to the Honorable Alex Kozinski of the Ninth Circuit. Ben is a past Chair of the American Bar Association’s Council of Appellate Lawyers and of the State Bar of Arizona’s Appellate Practice Section, Intellectual Property Section, and E-Commerce & Technology Section.

In addition to appellate advocacy, Ben works closely with trial counsel, taking the lead on or assisting with preservation of error, dispositive motions, class-action certification, motions in limine, jury instructions, and post-trial motions. He is the lead author of Thomson Reuters’s Arizona Trial Handbook and the longest-serving member of the State Bar of Arizona’s Civil Jury Instructions Committee.
