Defenses Flashcards
Insanity - Possible Rules
- M’Naghten Rule
- Irresistible Impulse Test
- Durham Test
- ALI or MPC Test
Insanity - M’Naghten Rule
- def doesn’t know right from wrong or doesn’t understand his actions
- technically also need a disease of the mind to have caused this defect of reason
Insanity - Irresistible Impulse Test
- an impulse that def cannot resist
- b/c of mental illness, def unable to control actions or conform conduct to the law
Insanity - Durham Test
- but for the mental illness, def wouldn’t have done the act
- def entitled to acquittal if the crime was the product of their mental illness
- broader than the other tests, but only followed in New Hampshire
MPC Test
- combo of M’Naghten + irresistible impulse
- def entitled to acquittal if had a mental disease or defect +, as a result, lacked the substantial capacity to either 1) appreciate the criminality of their conduct, or 2) conform their conduct to the requirements of the law
Insanity - Procedural Issues
- def must raise + often prove insanity
- def can raise insanity at arraignment, but doesn’t forego right to do so w/ not guilty plea (can raise later)
- if def does NOT raise insanity issue, def may refuse a court-ordered psychiatric exam to determine competency to stand trial (can’t refuse exam by court-ordered psychiatrist if did raise insanity though)
Diminished Capacity
- recognized as a defense in some states
- def may assert that as result of mental defect short of insanity, they didn’t have the mental state required for the crime charged
Intoxication - Overall
- may be cause by any substance
- may be raised whenever it negates one of the elements of the crime
- law usually distinguishes between voluntary + involuntary
Voluntary Intoxication
-result of intentional taking w/o duress of a substance known to be intoxicating
- may be offered only if crime requires purpose or knowledge, + intoxication prevented def from forming that
-> might work as defense to specific intent crimes
-> BUT not for general intent, malice or strict liability
- note that MBE considers addiction/alcoholism voluntary intoxication
Involuntary Intoxication
- results from taking of an intoxicating substance w/o knowledge of its nature, under direct duress imposed by another, or pursuant to medical advice while unaware of substance’s intoxicating effect
- may be treated as a mental illness
-> def entitled to acquittal if they meet the jur’s insanity test
Infancy
- common law - no liability for act committed by child under 7 + rebuttable presumption for 7 to 14, then treated as adults
- modern - often provide no child can be convicted of a crime until a stated age, usually 13 or 14, BUT can be found “delinquent” in special juvenile or family courts
Self-Defense - Nondeadly Force vs. Deadly Force
- nondeadly force generally justified where appears necessary to avoid imminent injury or retain property
- vs. deadly force justified only to prevent death or serious bodily injury
Self-Defense - Non-Deadly Force
- person w/o fault may use nondeadly force if reasonably believes necessary to protect self from imminent use of unlawful force upon self
- no duty to retreat
Self-Defense - Deadly Force
May use deadly force in self-defense if:
1) w/o fault
2) confronted w/ unlawful force AND
3) reasonably believes that they’re threatened w/ imminent death or great bodily harm
Deadly Force - Retreat
- generally no duty to retreat
- minority view - requires retreat if victim can do so safely unless attack in victim’s own home, while victim making lawful arrest, or while assailant robbing victim
