Practice Areas
Trey Cox is Co-Chair of Gibson Dunn's global Litigation Practice Group. Chambers USA ranks him Band 1 in Litigation: Trial Lawyers (Texas), Litigation: General Commercial (Dallas/Fort Worth), and Texas Regional Spotlight — and has ranked him continuously since 2009.
He is a nationally recognized trial lawyer whose practice is centered on bet-the-company commercial disputes, energy litigation, securities litigation defense, technology litigation, trade secret cases, defamation, and high-exposure jury trials. He represents companies, boards, senior executives, and investors when the stakes are highest and the result cannot be delegated to someone less experienced in front of a jury.
He has tried more than 50 complex commercial disputes to verdict and handled more than 100 bench trials, arbitrations, and evidentiary proceedings across federal and state courts.
Recent landmark matters include:
Energy Transfer LP and Dakota Access Pipeline — Lead trial counsel in a three-week jury trial resulting in a $667 million verdict, the largest in North Dakota history, on claims including trespass, conversion, civil conspiracy, and defamation against Greenpeace. Recognized as AmLaw's "Litigator of the Week."
Meta — Lead trial counsel defending Meta against a $300 billion biometric-privacy action brought by the Texas Attorney General under Texas privacy law.
World's Largest Windfarm — Secured a take-nothing verdict after a three-week jury trial in Abilene, Texas, in a mass-action nuisance case brought by surrounding landowners. Defended the verdict through the Texas Supreme Court.
GameStop — Lead trial counsel in federal district court in Delaware in a dispute with Bain Consulting Group over the validity of hundreds of millions of dollars in consulting contracts.
Clients hire Trey Cox when complexity is high, exposure is existential, and the jury box is in play. His practice is distinguished by a systematic methodology for translating massive evidentiary records into clear, persuasive trial narratives — and by a documented track record of winning them.
His work has been featured in The Wall Street Journal, The New York Times, The Los Angeles Times, Bloomberg News, The Dallas Morning News, and the Houston Chronicle.
He is a Fellow of the American Board of Trial Advocates and the Litigation Counsel of America, and he holds dual board certification in Civil Trial and Civil Pre-Trial from the National Board of Trial Advocacy. He lectures regularly at the University of Virginia School of Law, the University of Texas School of Law, and SMU Dedman School of Law on trial strategy, juror attention, and courtroom persuasion.
