What is relevant evidence admissible in a personal injury case?

Only relevant evidence is admissible. (Evid. Code, 350.) Relevant evidence is evidence "having any 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 has discretion to exclude relevant evidence when its prejudicial effect substantially outweighs its probative value. (Evid. Code, 352.) Evidentiary rulings are reviewed for abuse of discretion and a court's decision will be upheld unless it exceeds the bounds of reason. (People v. Williams (1997) 16 Cal.4th 153, 196-197.)
