Appellate

Described as “a superbly talented appellate bench” (Chambers USA 2017, Chambers & Partners), our nationally-recognized Appellate Practice Group has earned this recognition through decades of dedication to our clients, working successfully with trial lawyers, and gaining the respect of judges across the country. The reputation extends to all of our appellate lawyers based in Texas, Colorado, California and New York.

With one of the largest full-time appellate teams of any national law firm, our Appellate Practice Group offers more than general appellate proficiency. We have the depth to match clients with appellate lawyers who offer personal experience with specific industries, procedural issues, and courts. Our lawyers have argued appeals before the U.S. Supreme Court, the federal circuit courts of appeals, and all levels of state appellate courts, setting precedents for our clients in jurisdictions from coast to coast.

Across the country, we know the judges, and the judges know us. Most of our appellate lawyers have clerked for federal or state court judges, and five are members of the prestigious American Law Institute. Our lawyers have chaired numerous national and state appellate law bar groups, including the American Bar Association’s Council of Appellate Lawyers. We also are regularly invited by judges to speak at judicial conferences as the lawyers chosen to help judges stay informed about complex areas of law.

We earn our reputation not only in the appellate courts, but also through our work at the trial level. What appellate lawyers do before judgment is often as important as what they do afterwards. We collaborate with in-house counsel and lawyers at Haynes and Boone and other firms to shape litigation strategy, preserve error, prosecute and defend expert witness challenges, prepare and argue the jury charge, and prepare all manner of legal briefing before, during, and after trial. After a judgment is signed, we use cutting-edge empirical studies to evaluate and predict the likely outcome of the appeal.

Because of our reputation and proven results, clients often hire us at the recommendation of lawyers at other firms who recognize our skill and experience in a broad array of procedural areas, including:

  • Summary judgment motions
  • Jury charges
  • Judgment formation
  • Writs of mandamus
  • Superseding and enforcing judgments
  • Appellate Advocacy
  • Amicus curiae briefs
  • Arbitration-related litigation

The Texas Lawbook profiles Haynes and Boone Partner Nina Cortell as "widely respected as one of the best and most successful appellate lawyers in Texas. She broke through glass ceilings, gracefully convinced leaders of the legal profession to hire and promote more women and proved through her actions that gender was not a factor when it comes to being a great advocate."
