Proskauer’s award-winning Appellate & Legal Strategy Group has a deep and distinguished track record of handling precedent-setting and bet-the-company appeals in federal and state courts nationwide, including at the United States Supreme Court.
We litigate some of today’s highest-profile appeals across a broad spectrum of industries and legal issues, earning a reputation for excellence in appellate advocacy. Our clients have included T-Mobile, Wells Fargo, Johnson & Johnson, Church & Dwight, Amgen, Shire, Sanofi, Charles Schwab, McDonald’s, Toll Brothers, the NBA, the NFL, Major League Baseball, Major League Soccer, Cedars-Sinai, Michaels Stores, Sandoz, Bloomberg L.P., and the Financial Oversight and Management Board for Puerto Rico, among many other leading companies and organizations. We have successfully litigated appeals involving high-stakes constitutional, bankruptcy, labor and employment, antitrust, intellectual property, criminal, and commercial matters. Our experience spans industries ranging from sports and healthcare to financial services, entertainment, real estate, consumer products, life sciences, and asset management. In our most recent case at the U.S. Supreme Court in 2026, we prevailed 9-0 on behalf of the IAM National Pension Fund in an important case brought under the Employee Retirement Income Security Act of 1974 (ERISA).
We collaborate with colleagues across the Firm’s practice groups, blending our appellate expertise with their substantive knowledge to develop winning strategies from the outset. We also serve as a resource to the Firm’s trial teams, advising on strategy and spearheading dispositive motion practice to maximize the potential for success on appeal. By combining our trial and appellate strengths, we position our clients for victory at every stage of litigation.
Our team includes appellate litigators across multiple offices nationwide. Our lawyers have clerked for Supreme Court Justices and judges on the First, Second, Third, Sixth, Seventh, Ninth, and Tenth Circuits, offering specialized insight into key appellate forums. Our associates receive hands-on appellate experience early in their careers, drafting winning briefs and arguing appeals in federal and state appellate courts. This depth of experience allows us to staff appeals leanly, delivering outstanding results at lower cost.
Our work has been recognized by the National Law Journal, the American Academy of Appellate Lawyers, Law 360, Super Lawyers, The Legal 500, and Benchmark Litigation, among other organizations.
We are also deeply committed to pro bono appellate advocacy. Through our service on the Second Circuit’s Pro Bono Panel, we have successfully represented incarcerated individuals in multiple appeals. In 2026, we prevailed in an appeal brought in conjunction with the Ohio Innocence Project.
Beyond litigation, we contribute to the appellate bar through writing and teaching. We lead PLI’s annual seminar on appellate advocacy and serve as editors and authors of Principles of Appellate Litigation: A Guide to Modern Practice (PLI Press), a comprehensive treatise on appellate practice updated annually.
With deep appellate experience, an unwavering commitment to excellence, and a track record of success in the nation’s highest courts, Proskauer’s Appellate & Legal Strategy Group delivers results in the cases that matter most.
