Jon Mureen is the managing partner of the Dallas office. He is a first-chair trial lawyer for sophisticated business disputes, marked by his ability to grasp complex issues and communicate them simply and persuasively to a jury or judge. Clients call on Jon to take their highest-stakes cases to trial.
“Jon is highly intelligent, tenacious, and always calm under pressure,” says Denis Boulle, CEO of De Boulle Diamond & Jewelry. “And perhaps most important, the jury absolutely loved him!”
Jon has well over 100 days of first- and second-chair trial experience from about 15 trials. He enjoys both the stand-up and intellectual sides of practice – i.e., the legal analysis, factual development, clear writing, witness preparation and courtroom presence all needed to present complex issues simply and persuasively to a judge or jury.
Jon has particular experience in corporate shareholder, partnership and governance contests, fraud and fiduciary duty cases and bankruptcy litigation. In his most recent trial (2024), he first-chaired the claims of minority shareholders against a controller for breach of fiduciary duty in a cash-out merger, in Delaware Chancery Court. Over the course of his nearly two decades of practice, he has led trial teams in a variety of other settings.
Whatever the issue, clients know Jon will take ownership, find the path to victory and get there quickly and efficiently. While this sometimes means a negotiated settlement, his philosophy is that the most favorable settlements usually come through superior trial preparation.
“Jon is a smart and savvy litigator who gets great results and gives excellent counsel,” says Carolyn Vaughn, President of VES Survey International. “He is someone I can trust with anything.”
Jon began his career with a clerkship for the Honorable Sidney A. Fitzwater, Chief Judge of the US District Court for the Northern District of Texas.
