Summary
Amends the Federal criminal code to make it a defense to a Federal prosecution that the defendant, as a result of mental disease or defect, lacked the state of mind required as an element of the offense (current law contains no statutory insanity defense). Authorizes a special verdict of "not guilty only by reason of insanity" for any criminal defendant who raises the issue of insanity by notice as provided by Rule 12 of the Federal Rules of Criminal Procedure. Requires that any person found not guilty only by reason of insanity be committed to a facility until eligible for release. Requires the court to commit such person to the custody of the Attorney General upon a finding by clear and convincing evidence that the person is currently suffering from a mental disease or defect and his release would create a significant risk of bodily injury to another person or serious damage to property of another. Directs the Attoney General to release such person to a State which will assume responsibility for his custody and treatment or otherwise to hospitalize such person in a suitable facility. Requires the court to hold a hearing upon the certification by the director of the facility that such person's release will no longer create significant risk of injury or property damage. Directs the court to order the discharge of a person who is found to have recovered. Provides for the hospitalization of convicted persons who are found to suffer from mental disease or defect.
