What is relevant evidence in a personal injury case?

As defendant's rule is unsupported by authority, we instead apply Evidence Code section 210, which defines relevant evidence as evidence "having any tendency in reason to prove or disprove any disputed fact that is of consequence to the determination of the action." (Italics added.) "'The test of relevancy is whether the evidence tends, logically, naturally, or by reasonable inference to establish a material fact, not whether it conclusively proves it. [Citation.]' [Citation.] '"[T]o be admissible, evidence need not absolutely confirm anything. It is axiomatic that its weight is for the jury." [Citation.]' [Citation.]" (People v. Dellinger (1984) 163 Cal.App.3d 284, 307.)
