Ben Cooper, a partner based in Steptoe’s Phoenix and San Francisco offices, is a nationally recognized appellate lawyer.  Author of Federal Appellate Practice: Ninth Circuit (2015-2016 ed.), a 1,500-page treatise published annually by Thomson Reuters, Mr. Cooper is respected as a leading practitioner before the US Court of Appeals for the Ninth Circuit, which covers nine western states and two Pacific Island territories.  In addition, he has represented parties and amici curiae in the US Supreme Court; the US Courts of Appeals for the Second, Third, Fifth, Tenth, Eleventh, DC, and Federal Circuits; and state appellate courts from Hawaii to North Carolina, including oral arguments before the supreme courts of Arizona, California, New Mexico, and Pennsylvania. He is ranked in Best Lawyers in America and Southwest Super Lawyers for appellate law.

By court appointment, Mr. Cooper served from 2009-2012 as chair of the first group of Appellate Lawyer Representatives to the Ninth Circuit Judicial Conference.  He began his legal career as a law clerk to Ninth Circuit Judge (and later Chief Judge) Alex Kozinski.

Mr. Cooper is a past chair of the American Bar Association’s Council of Appellate Lawyers, which is part of the ABA Appellate Judges Conference.  He is also the immediate past chair of the State Bar of Arizona’s Appellate Practice Section and a longtime member of its Civil Jury Instructions Committee.  Among his other works, Mr. Cooper is the lead author of the Arizona Trial Handbook (Thomson Reuters 2015-2016 ed.), which addresses the law of all aspects of civil and criminal trials in Arizona courts.  

Representative Matters

Mr. Cooper handles appeals, writs, and special actions in appellate courts, and also works closely with trial counsel before any appeal, collaborating or taking the lead on preservation of error, dispositive motions, class action certification proceedings, motions in limine, jury instructions, and post-trial motions. His practice encompasses a broad range of substantive fields, but most frequently involves him in insurance coverage, bad faith, and punitive damages matters; professional liability defense; federal, state, and local taxation; intellectual property and e-commerce; public pension plans, employment, and labor litigation; and other complex civil and constitutional litigation.
