Study Notes
Insanity Overview
- Insanity refers to mental abnormalities impacting legal responsibility, not a psychiatric condition.
- Key tests for determining insanity: M'Naghten, irresistible-impulse, Durham rule, and Model Penal Code test.
- Sociopathic and psychopathic behaviors are excluded from these tests.
- Defendants questioning their sanity can be mandated to undergo psychiatric evaluations, respecting their Fifth Amendment rights.
M'Naghten Test
- A defendant is not guilty if, due to a mental disease, they did not understand the nature or wrongfulness of their actions.
- Key aspect involves assessing if the defendant's actions would have been criminal based on their understanding influenced by delusions.
- Believing one's actions are morally right does not automatically lead to exculpation, although some states may accept this defense.
- Loss of control due to mental illness does not apply under this test, often referred to as the "right from wrong" test.
Irresistible-Impulse Test
- A defendant is deemed not guilty if a mental disease or defect hinders their ability for self-control and free choice.
- The inability to conform conduct to legal standards is central; loss of control need not be sudden but must be an irresistible impulse.
Durham Rule
- A defendant is not guilty if their unlawful act is a direct product of a mental disease or defect, fitting the "but-for" test.
- Emphasizes causation between mental illness and the criminal act.
Model Penal Code Test
- This test merges aspects of the M'Naghten and irresistible-impulse tests.
- A defendant is not guilty if, due to mental disease or defect, they lack substantial capacity to appreciate the wrongfulness of their act or to conform to the law.
Burden of Proof
- Generally, the burden of proving insanity lies with the defendant in most jurisdictions.
- Proof standards can vary, requiring either preponderance of evidence or clear and convincing evidence.
- In some jurisdictions, the defendant must present evidence of insanity, shifting the burden of proof to the prosecution to establish sanity beyond a reasonable doubt.
