Gibson, Dunn & Crutcher is renowned for its award-winning Appellate and Constitutional Law Practice Group, one of the largest and most experienced appellate practices in the nation. Each year, we present arguments in the Supreme Court of the United States, all 13 federal courts of appeals, and state appellate courts throughout the country. We work closely with trial teams to preserve arguments and develop a winning litigation strategy. When the occasion calls for it, we also develop novel or complex legal theories, sometimes long before the suit is filed. No firm has a stronger record of appellate success.
