Criminal Law Flashcards
Two elements of all crimes
(1) Actus reus (voluntary act)
(2) Mens rea
When does failure to act violate a duty in criminal law?
Duty can be imposed by:
(1) Statute imposed
(2) Contract
(3) Special relationship (parent-child)
(4) Detrimental undertaking (offering victim help)
(5) ∆ creates peril (failing to aid after causing victim’s peril)
Specific intent crimes
Requires a subjective desire, objective, or knowledge.
Examples:
(1) First-degree murder
(2) Inchoate offenses (attempt, solicitation, conspiracy)
(3) Assault with intent to commit battery
(4) Theft offenses (larceny, false pretense, embezzlement, forgery, burglary, robbery)
Malice crimes
Only require a reckless disregard of a high risk of harm. Requires only a criminal act without an excuse, justification, or mitigation.
(e.g., murder or arson)
General intent crimes
Requires only an intent to perform an act that is unlawful. Generally done knowingly, recklessly, or negligently. Examples: (1) battery (2) rape (3) kidnapping (4) false imprisonment
Accomplice liability
A person who (1) with intent that the crime be committed (2) aids or abets a principal prior to or during commission of a crime.
Person who is in a class protected by statute cannot be an accomplice (minor cannot help statutory rape).
Withdrawal from accomplice liability
Requires:
(1) Repudiate prior act
(2) do all that is possible to countermand prior assistance
(3) must do so before the chain of events is in motion and unstoppable.
Accessory after the fact
Guilty of obstruction.
M’Naghten test for insanity

(2) ∆ did not know the nature and quality of the act OR the wrongfulness of the act
Irresistible Impulse test for insanity

(2) prevented defendant from being able to conform his or her conduct to the law
Durham Rule (But-for test) for insanity

(2) crime could not have been committed but-for the disease or defect
MPC Test for insanity
(1) as a result of a mental disease or defect
(2) defendant did not have the substantial capacity to appreciate the wrongfulness of the act OR to conform conduct to law.
Four tests for insanity
(1) M’Naghten test
(2) Irresistible Impulse test
(3) Durham Rule (but-for test)
(4) MPC test
Voluntary Intoxication
Defense for specific intent crimes, but NOT general intent or crimes of malice, recklessness, or negligence.
Involuntary intoxication
Defense to any crime where intoxication might negate an element of the crime.
Must show: (1) without knowledge of the intoxicating nature of the substance OR (2) took it under duress.
Infancy defense (common law)
∆ cannot be convicted unless 7yo or older. If between 7 and 14, rebuttable presumption of incapability. 14 or older is tried as adult.
Four kinds of murder
(1) intent to kill
(2) intent to inflict serious bodily harm
(3) depraved heart killing (Russian roulette, firing into crowd, etc.)
(4) Felony murder (“BARRK” = Burglary, Arson, Robbery, Rape, kidnapping.)
Voluntary manslaughter
Intentional killing in response to adequate provocation.
Provocation = threat of serious battery or deadly force, discovery of adultery. Words are not enough. No cool-off time.
