Negating Mens Rea Flashcards
List
Ways to negate mens rea
Mistake
Insanity
Intoxication
Mistake - Mistake of Law
Defintion - claim that conviction would be wrongful because he thought law was different from what it was though ignorance from what it was (good faith belief legal)
Exceptions to Ignorance =/ Excuse:
- Reliance on high level government interpretation of the law
- Lack of Notice (nowhere to find law)
- Mistake of law that goes to an element of specific intent (applies only to the FIAT crimes or specificc intent crimes)
- if crime with which D is charged is a specific intent crime, then a D can argue that his belief that his conduct was legal will negate that element of the offense
Mistake - Mistake of Fact
Starting Point - ask whther the crime is a strict liabilty crime, a general intent crime, or specific intent crime
Strict Liability - mistake of fact is never a defense
General Intent - mistake of fact isa defense only if the mistake is reasonable and it goes to the criminal intent
Note - the transferred intent doctrine means that it is never a reasonble mistake of fact to say “I thought I was committing a crime against X, not Y:
Specific Intent Crimes - mistakes of fact are a defense anytime the D actually held the mistaken belief, whether it was reasonble or unreasonble
Insanity
Four Different Test
- M’Naghten - D either did not know the nature of the act or did not know that the act was wrong
- Irresistible Impulse - D has a mental disease or defect that meas the D cannot control himself
- Durham Rule - D would not have committed the crime but for his having a mental disease or defect (very D freindly)
- MPC - due to a mental disease or defect, the D did not have substantial capacity to appreciate the wrongfulness of his acts or to conform his conduct to the law
Note - all four tests requrie that the D have a mental disease or defect
Intoxication
Substances - covers alchohol, drugs, and medications
Involuntary - occurs when:
- doesnt realiie that she received an intoxicating substance
- is forced or cooerced into ingesting a substance; or
- has an unexpected or unanticipated reaction to a prescription medication
When does it work - can be a valid defense to general intent, specific intent, and malice crimes when it negates the mens rea necessary for those crimes
Voluntary Intoxication - occurs when a person willingly ingests the substance, knowing that it was an intoxicant
When does it work - only a defnse to specific intent crimes (FIAT) and only if it prevent the D from forming the mens rea; not a valid defense if D got drunk in order to commit crime
