Notable Trial Experience

Ghezavat: Defense verdict on behalf of neurologist and hospital in a wrongful death action involving a fatal auto accident caused by these defendants’ former patient. Plaintiffs claimed the neurologist violated Health and Safety Code §103900 by not filing a report informing the local health officer that the patient/driver suffered from a "disorder characterized by lapses of consciousness." The neurologist and hospital maintained there was no violation of §103900 under an associated regulation, 17 CCR §2812, which provides there is no obligation to report if--as had occurred in this case--the patient states that he or she does not drive, states that he or she never intends to drive, and the physician believes these statements made by the patient are true.

During the four-week trial, plaintiffs asked the jury to award $41.18 million in damages. The jury concluded the neurologist had not violated the reporting statute and found in favor of both the neurologist and the hospital; 2018.

In the Matter of Dr. A: Represented physician through administrative hearing and appeal following Medical Board’s denial of licensure, resulting in issuance of full license with no conditions; 2015.

Watson: Dismissal of all claims on day of trial. Plaintiff had alleged lack of informed consent with respect to the medication Zometa; 2014.

Simons: Dismissal of all claims during trial. Plaintiffs alleged the physician had negligently delayed completion of a decedent's death certificate; 2013.

Robbins: Defense trial verdict on behalf of physician in a claim alleging failure to monitor patient (also a physician) taking prescription medication; 2011.

Landry: Defense trial verdict on behalf of a hospital and physicians involving allegations of medical negligence and wrongful death due to a ruptured aorta during a cardiac stenting procedure; 2006.
