In one of his last rulings before leaving the bench after 13 years, U.S. District Judge Leonard Davis of the Eastern District of Texas dramatically erased a $25 million jury verdict. Davis based his ruling on what he described as “without question the worst conduct this court has ever seen.”

Davis vacated the verdict because of the fraudulent actions during the trial by corporate plaintiff LBDS, a Richardson-based holding company. LBDS’ actions included document forgery, and the company misled its own lawyers, opposing counsel, Davis himself and the jurors, the judge wrote.
