What is relevant evidence in a personal injury action?

Relevant evidence is defined as having a "tendency in reason to prove or disprove any disputed fact that is of consequence to the determination of the action." (Evid. Code, 210.) A trial court may exclude otherwise admissible evidence if its probative value is substantially outweighed by its prejudicial effect; that is, if its admission would result in the undue consumption of time, a danger of undue prejudice, confusion about the issues or the danger of misleading the jury. (Evid. Code, 352.) "Cumulative evidence may be excluded on this basis. [Citation.]" (People v. Mincey (1992) 2 Cal.4th 408, 439.)
