California Appellate

Arnold & Porter has broad experience in the California appellate courts and the federal appellate courts, with particular focus on the Ninth Circuit. Our deep bench has been repeatedly recognized for its excellence and our appellate lawyers are active leaders in state and national appellate associations. Our team includes appellate specialists certified by the State Bar of California, members of the selective California Academy of Appellate Lawyers, members of the invitation-only American Academy of Appellate Lawyers, former clerks at the Ninth Circuit, and the former chair of the State Bar of California. We bring thorough, careful and objective analysis, systematically identifying not only winning arguments but also challenges that must be overcome. Through lively writing and compelling storytelling, we understand that a sympathetic factual presentation can be just as important to success as a powerful legal argument.
