Our Supreme Court and Appellate Litigation team has represented clients in scores of complex civil and criminal appeals in all federal courts of appeals. We honed our experience in some of the most complex areas of the law, including federal and state taxation, employee benefits and ERISA, international business, criminal defense, and federal preemption. The breadth of our representations has made us sensitive to the issues facing appellate judges with wide-ranging case loads and equipped us to get up to speed quickly and to handle effectively any kind of issue at the appellate level.

Our clients include some of the world's largest U.S. and foreign-based corporations, trade associations, industry coalitions, individuals, and public interest groups. Clients hire us for our experience, our ability to handle the most sophisticated matters, and our record of achievement in court.  In addition to serving as lead counsel in appeals, our team is also regularly engaged to revise appellate briefs prepared initially by other counsel and to provide skilled advice on Supreme Court or appellate strategy and procedure in important cases. We often provide advice to counsel at the trial level, including strategic guidance at the early stages of a case. Our team advises in framing legal theories, shaping important statutory or constitutional issues, and preserving issues for appeal with an eye to subsequent appellate consideration.
