In People v. Pennington (1967) 66 Cal.2d 508, sufficient evidence of such incompetence consisted of the following: The expert opinion of a qualified psychologist based upon a previous diagnosis of schizophrenia and paranoia, a current diagnosis of a more paranoid condition; defendant's current unfeigned hallucinations and defendant's fits of psychotic furor observed by witnesses in the courthouse and during the trial. And further People v. Pennington, supra, held that the testimony of the first psychologist "was by itself substantial evidence which compelled the court to order a section 1368 hearing."
