An insanity defense means that a defendant is not guilty of the crime because they didn't have the mental capacity required to commit a crime. If you are found not guilty by reason of insanity you could still be committed to a psychiatric institution.
The A.L.I. formulation provides that a defendant will not be held criminally responsible if at the time of the behavior in question "as a result of a mental disease or defect, he lacks substantial capacity either to appreciate the criminality of his conduct or to conform his conduct to the requirements of the law."
After a defendant makes this plea, he/she is usually sent to a state mental health facility, a county mental health evaluation and treatment facility or another mental health facility for up to 30 days.
What Happens After a Successful NGI Defense? A successful NGI defense means that defendant will not be incarcerated in a jail or prison, but rather will spend time in a state mental hospital until doctors determine their sanity has been restored.
How does an insanity plea affect sentencing? If you successfully plead the insanity defense, then you will not receive the normal jail/prison sentence for your crime. Instead, you will be committed to a state mental hospital.
The Insanity Defense in Practice Despite public fears, defendants do not abuse the insanity defense. In felony cases, the defense is invoked less than 1% of the time, and even when it is employed, it is only successful 25% of the time.
Most courts have held that diagnoses such as schizophrenia, major depressive disorder, and bipolar disorder qualify as a mental disease for the purpose of insanity. Diagnoses such as personality disorders, paraphilias, and voluntary substance intoxication do not usually qualify.
Penal Code section 1026, et. Seq. Legal insanity requires that the person, by reason of mental disease or defect was incapable of either: Knowing the nature of his or her act. Understanding the nature of his or her act. Distinguishing between right and wrong at the time of commission of the crime.
The four tests for insanity are the M'Naghten test, the irresistible-impulse test, the Durham rule, and the Model Penal Code test. These tests expressly exclude the "sociopathic" or "psychopathic" criminals who have a tendency to commit antisocial and sometimes violent acts and are incapable of experiencing guilt.
In reality, however, various criminal studies have established that only about one percent of all felony cases in the United States involve use of the insanity defense. Moreover, even when the defense is asserted, it is successful in only about 30 cases every year.
