In Lockley v. Law Office of Cantrell, Green, Pekich, Cruz & McCort (2001) 91 Cal.App.4th 875, the court said, " 'Judicial notice is the recognition and acceptance by the court, for use by the trier of fact or by the court, of the existence of a matter of law or fact that is relevant to an issue in the action without requiring formal proof of the matter.' . . . However, while courts are free to take judicial notice of the existence of each document in a court file, including the truth of results reached, they may not take judicial notice of the truth of hearsay statements in decisions and court files. Courts may not take judicial notice of allegations in affidavits, declarations and probation reports in court records because such matters are reasonably subject to dispute and therefore require formal proof. The underlying theory of judicial notice is that the matter being judicially noticed is a law or fact that is not reasonably subject to dispute." (Id. at p. 882.)
