In the case of Victalic Company v American Home Assurance Company the First District Court of Appeal made it very clear that denials to Requests for Admissions are inadmissible. Here is the court’s reasoning starting at page 23 of the published opinion:
Gonsalves v. Li (2015) 232 Cal.App.4th 1406 (Gonsalves) involved an automobile accident. Plaintiff called defendant as an adverse witness and asked about his qualified denials of plaintiff’s RFAs that he was responsible for the accident. And in closing argument, plaintiff emphasized that the denials were evidence defendant refused to take responsibility for plaintiff’s injuries. (Id. at p. 1413.) The jury returned a verdict for plaintiff for $1,208,642.86. (Id. at p. 1411.) Our colleagues in Division Five reversed, holding it was error for the trial court to allow questions about RFAs.
