Notable Verdicts

Bryan Stow v. Los Angeles Dodgers
Litigation Support Professionals worked with Lewis Brisbois Bisgaard Smith (Los Angeles) for 6 weeks defending the Los Angeles Dodgers in the Superior Court of California- County of Los Angeles. After 9 days, the jury came back with a verdict. The jury found Louis Sanchez and Marvin Norwood each 37.5% liable, and the Dodgers were apportioned the remaining 25%. The plaintiff was seeking damages in excess of $60 million. Defense attorney Dana Fox commented, “the jury clearly rejected the plaintiff's numbers and followed the evidence of damages offered by the defense. While no one could deny this man suffered significant, life-altering injuries and you have to feel sympathy for Mr. Stow, the jury clearly concluded the plaintiff's claimed numbers were not supported by the evidence.”
