Kastner v. Los Angeles Metro. Transit Auth

In Kastner v. Los Angeles Metro. Transit Auth. (1965) 63 Cal.2d 52, the California Supreme Court upheld the admission of expert testimony by an investigating officer as to the point of impact of an accident wherein a bus struck a pedestrian, even though based largely upon statements made by the defendant, because that witness testified to the same facts at trial: "Opinion evidence based on hearsay is inadmissible. The officer's opinion, however, although based to a large extent upon defendant's statement made outside the courtroom, was not based upon hearsay evidence, because defendant . . . testified on the witness stand to the identical facts which were included in his statement." (Id. at p. 58.)
