Representative Matters

• Lead trial counsel for Energy Transfer LP as well as its senior officers and directors in both E.D. Pennsylvania and N.D. Texas securities class action and shareholder derivative actions challenging statements regarding various pipeline construction projects.
• Lead trial counsel for Energy Transfer LP and Dakota Access Pipeline in a historic
  $667 million verdict in a trespass and defamation case. The jury’s decision marked the largest verdict in North Dakota’s history. The Gibson Dunn team’s strategic focus on ground torts and defamation claims led to favorable outcomes on multiple counts, including trespass, conversion, nuisance, civil conspiracy, and defamation. The verdict serves as a powerful affirmation of the First Amendment.
• Lead trial counsel for Meta in $300B case brought by Texas Attorney General Ken Paxton, claiming Meta captured and used the biometric data of Texans without properly obtaining their informed consent to do so, in violation of Texas privacy laws.
• Lead trial counsel for GameStop in lawsuit in the federal district court of Delaware with Bain Consulting Group over validity of hundreds of millions of dollars of consulting services contracts.

• Lead trial counsel for Purdue Pharma Opioid in bellwether state Attorney General claim in Oklahoma and federal MDL in Cleveland. This lawsuit was vitally important to the client, the pharmaceutical industry, and, more broadly, healthcare consumers nationwide as it pitted the principles of healthcare freedom of choice and patient access to medical care against the state’s claims for astronomical damages.
• After a three-week jury trial in Abilene, Texas, Trey secured a take-nothing verdict for his client, the largest windfarm in the world, in a mass action by surrounding landowners seeking to shut down the windfarm as a public and private nuisance. The win was heralded as a landmark decision for the wind energy industry. Trey successfully defended the verdict all the way to the Texas Supreme Court.

With the help of a former Texas state court judge, he has turned these interviews and insights into a book, The Jury Rules: The Rules Every Juror Wants Every Trial Lawyer To Know and Use.

Trey received a B.A., magna cum laude, from Washington & Lee University and his J.D. from the University of Virginia School of Law. After graduation, he clerked for the Honorable Jacques L. Wiener, Jr. of the United States Court of Appeals for the Fifth Circuit.
