People on trial for civil wrongs like negligence are entitled to present a vigorous defense. This often includes attempting to shift some or all of the blame for to the injured person. However, the law, while allowing the accused to present a defense, prohibits using evidence that is more likely to instill a bias in the jurors than it is to prove or disprove the issues before the jury. One recent example is a California Court of Appeal case where the court threw out a jury verdict because the trial court allowed the defense to present evidence of the deceased victim’s marijuana use, even though there was no connection between the drug use and the accident that took the victim’s life.
The fateful incident giving rise to the case occurred when Randy Hernandez was driving on the freeway in the pre-dawn hours of Feb. 28, 2010. Hernandez’s vehicle collided with one driven by Eric Lauderdale, leaving both vehicles disabled in the left lane. The men were standing near their vehicles when a sheriff’s deputy, who did not see the crashed vehicles, slammed into Lauderdale’s vehicle. The secondary accident sent Lauderdale over the five-foot-tall concrete barrier, but he suffered only a foot injury. Hernandez was killed.
Hernandez’s daughter sued Los Angeles County for negligence. At trial, the county introduced evidence that Hernandez had smoked marijuana and was possibly still under the influence when the accidents occurred. The county also claimed that Hernandez was responsible for the accident with Lauderdale. The jury deliberated and came back with a verdict finding the county 51% at fault, Lauderdale 35%, and Hernandez 14%.
