Title 18 › Part III— PRISONS AND PRISONERS › Chapter 313— OFFENDERS WITH MENTAL DISEASE OR DEFECT › § 4242
If a defendant files a notice under Rule 12.2 saying they will use an insanity defense, the court must order a psychiatric or psychological exam and have a report filed with the court if the government's lawyer asks, under section 4247(b) and (c). If the insanity issue is raised under Rule 12.2 by the defendant, the government's lawyer, or the court itself, the jury must be told to decide — or if there is no jury, the judge must decide — whether the defendant is guilty, not guilty, or not guilty only because of insanity.
