Key legal question
Whether the appellate court acted arbitrarily by relying on a private psychiatric report and refusing a court-appointed expertise on diminished responsibility.
Extracted holding
Yes. The court needed an official psychiatric expertise; the private report was insufficient to assess responsibility at the relevant times, and the appellate court assessed expert issues beyond its competence.
Extracted reasoning
The appellate court itself doubted the private report yet did not obtain an official expert opinion. It also ignored the possible impact of a narcissistic personality disorder. On the existing record it could not reliably assess diminished responsibility for the various offenses.
