In People v. Cooper (1991) 53 Cal.3d 771, a transcript was inadvertently admitted into evidence and reviewed by the jury during deliberations. Upon learning of the error, the court admonished the jury and questioned them to determine if they could disregard the exhibit. The Court of Appeal held that it was a case of simple error, not misconduct, and, as the evidence of guilt was strong, the exhibit was withdrawn, and the jury admonished to disregard it, there was no prejudice shown that would require a reversal.
