Los Angeles Team Secures Defense Verdict on Behalf of Landscaping Company - Los Angeles Partners Andrew C. Hubert and Nicholas T. Koumoulis recently secured a defense verdict when a Santa Monica jury determined that our client, an on-site landscaping company at a golf course, was not negligent in its maintenance of the course. The plaintiff, who was 59 years old at the time of the incident, claimed that the ground located on the bank of a creek that ran through the course gave out from under him due to erosion. The plaintiff’s only acute injury was a bacterial infection that he received through a puncture wound in his elbow. The plaintiff, however, was claiming a number of ongoing sinus and orthopedic injuries and seeking a significant award. Due to a C.C.P. 998 offer made prior to trial and as the prevailing party, our client will be able to pursue a significant cost bill for having to take the case through trial.
