John Turner is a trial lawyer who represents plaintiffs and defendants in civil litigation across the United States. He has led trial teams to successful results in areas ranging from intellectual property to contract disputes to fiduciary claims. He also has played a central part in a number of high profile public interest cases in Texas.
John believes strongly in public service and civic involvement. He currently serves in the Texas Legislature and has been the State Representative for House District 114 in Dallas since 2019. In the House, he has served on the Appropriations, Environmental Regulation, Higher Education, County Affairs, and General Investigating Committees.
During his 20-year litigation career, John has represented clients in a wide variety of industries, from semiconductor manufacturing to telecommunications to energy to financial services. John handles matters in state court, in federal court, and in arbitration. He also has served as the co-chair of the firm’s Trade Secret Litigation Practice Group.
In every litigation matter, John emphasizes a few basic practices:
- Presenting the law and the facts clearly to the decision-maker
- Focusing on the core issues – and avoiding unnecessary disputes that consume time and energy
- Communicating effectively and often with the client about strategies and objectives.
In John’s experience, the strongest representation is fully compatible with high standards of ethics, courtesy, and professionalism.
John grew up in the small east Texas town of Crockett and graduated from Crockett High School. He received degrees from Harvard College and Yale Law School, where he won the Thurman Arnold Prize as the best oral advocate in the school’s moot court competition. He served as a law clerk for the Honorable Lee H. Rosenthal of the United States District Court for the Southern District of Texas.
Before joining Haynes Boone in 2008, John was a partner in the Dallas office of Susman Godfrey, LLP.
- Represented a coalition of 88 Texas school districts in landmark litigation related to the adequacy of the school finance system in Texas. After trial, the district court ruled in favor of the school districts, finding that the system had evolved into an unconstitutional state property tax and did not provide funding sufficient to meet constitutional standards. While the Texas Supreme Court ultimately reversed the trial court’s judgment, the case influenced subsequent policy discussions about public education in Texas.
- Represented the Halliburton Company in an arbitration in which the claimant alleged that Halliburton had misappropriated technology related to water treatment in hydraulic fracking. The claimant sought $300 million in damages. After a two-week evidentiary hearing, a three-arbitrator panel found that Halliburton did not misappropriate any technology and awarded zero damages.
- Represented Halliburton as the plaintiff in a two-week jury trial in Dallas County, in which the jury awarded damages to Halliburton for another party’s trade secret misappropriation in the exact amount requested.
- Represented the Dallas Police and Fire Pension System in several high-profile disputes related to the system’s efforts to improve its long-term financial stability.
