What is relevant evidence in a personal injury action?

Evidence is relevant if it has a "tendency in reason to prove or disprove any disputed fact that is of consequence to the determination of the action." (Evid. Code, 210.) However, the trial court may exclude relevant evidence if the risk of undue prejudice, undue consumption of time, confusion of the issues, or misleading the jury substantially outweighs its probative value. (Evid. Code, 352; People v. Cudjo (1993) 6 Cal.4th 585, 609.)
