What is the test for admitting character evidence in a civil case?

First, evidence is relevant if it has "any tendency in reason to prove or disprove any disputed fact that is of consequence to the determination of the action." (Evid. Code, 210, italics added.) The reason for the general rule against the admission of character evidence is "not that such evidence is never relevant; to the contrary, the evidence is excluded because it has too much probative value." (People v. Guerrero (1976) 16 Cal.3d 719, 724, italics added.)
