Appellate

Our clients appreciate that Simpson Thacher is a formidable force in the appellate arena. They turn to us for our reputation for procuring against‑the‑odds, law-defining appellate rulings across a wide range of areas, including class actions, commercial, and securities litigation. Our litigators also maintain an active pro bono practice, regularly representing clients in high-impact matters in both federal and state appellate courts.

“The team is great. The firm offers a one-stop shop in handling matters right from litigation to appeal. There are few firms that I would consider doing this with, Simpson Thacher is one of those firms.”
The Legal 500 U.S., quoting a client

Clients have described our team as “thoughtful and effective oral advocate[s],” who have won significant law-defining appeals, achieved affirmances for winning outcomes below, and turned the tide to reverse unfavorable rulings. Our deep bench includes former law clerks to federal and state appellate judges across the country, and former federal prosecutors with extensive experience arguing before federal courts of appeals.

“They think outside the box and are willing to explore creative approaches to legal situations.”
Chambers USA, quoting a client

We are well known as a “one-stop shop” for matters from litigation through appeal, but also for our ability and willingness to effectively partner with counsel at other firms who first litigated and tried a case.

Our impressive track record of success in defending wins and reversing losses for our clients includes recently overturning a multimillion-dollar jury verdict in a groundbreaking product liability case before the New York Court of Appeals.
