Criminal Law MBE Flashcards
Actus reus
(i) a voluntary, affirmative act, or (ii) an omission (failure to act), causing a criminally proscribed result
Voluntary act
- Physical and voluntary
- Unconscious/asleep/under hypnosis—not voluntary
Failure to act when a duty exists
- Imposed by statute (e.g., the obligation to file a tax return)
- Contract (e.g., a lifeguard saving a drowning person)
- Special relationship (e.g., a parent’s duty to her child or the duty to one’s spouse)
- Detrimental undertaking (e.g., leaving a victim in worse condition after treatment)
- Causation (e.g., failing to aid after causing a victim’s peril)
Mens rea
—a guilty mind or legally proscribed mental state (no mens rea for strict-liability crimes)
Specific-intent (SI) crimes
—the defendant (D) has a subjective desire, specific objective, or knowledge to accomplish prohibited result (FIAT):
- First-degree murder
- Inchoate offenses
- Assault with intent to commit battery
- Theft offenses
Malice crimes
CL murder, arson
- Reckless disregard of a high risk of harm
- Does not require D to act with ill will toward victim
General-intent crimes
(e.g., battery, rape, kidnapping, and false imprisonment)
- Require the intent to perform an unlawful act
- Intent—purposely, knowingly, recklessly, or negligently
Transferred Intent
o When D acts with intent to cause harm to one person or object and that act directly results in harm to another person or object
o Applies only to “bad aim” cases (not mistaken identity)
o Usually confined to homicide, battery, and arson
o Not for attempted crimes (only completed crimes)
o MPC—transferred intent not specifically recognized, but liability is recognized when purposely, knowingly, recklessly, or negligently causing a particular result is an element of an offense.
MPC Purposely
D’s conscious objective is to engage in the conduct or to cause a certain result
MPC Knowingly/willfully
D is aware or knows that the result is practically certain to occur based on the conduct
MPC Recklessly
D acts with a conscious disregard of a substantial and unjustifiable risk
MPC Negligently
D should be aware of a substantial and unjustifiable risk that a material element of a crime exists or will result from the conduct (i.e., a gross deviation from the standard of care)
Strict-liability crimes
(e.g., statutory rape, bigamy, regulation of food and drugs)
- No mens rea; proof of the actus reus is sufficient for conviction
- Generally disfavored; there must be clear legislative intent to dispense with the mens rea
Vicarious liability
- No actus reus by D; imposes criminal liability on D for the actus reus of a third party
- Generally limited to regulatory crimes; punishment generally limited to fines
- Corporations—may be vicariously liable when the act is performed by a high-ranking corporate agent who likely represents corporate policy
Causation
D’s conduct must cause the particular result or circumstance
Mistake as a defense
may negate criminal intent if an “honest mistake”
Mistake of fact
o CL—a defense to specific-intent crimes, even if unreasonable; a defense to general-intent or malice crimes, only if reasonable
o MPC—serves as a defense if it prevents prosecution from establishing the required state of mind for a material element of a crime
o Strict liability—no defense
Mistake of law
—not valid under CL;
only valid under MPC if:
o An honestly held mistake of law negates required intent or mental state
o D relied on court decision/administrative order or official interpretation
o Statutory definition of malum prohibitum crime not available before conduct
Principal
—the person whose acts or omissions are the actus reus of the crime; must be actually or constructively present at the scene of the crime
Accomplice
—a person who, with the requisite mens rea, aids or abets a principal prior to or during the commission of the crime
Principal in the second degree
an accomplice who is physically or constructively present during the commission of the crime
Accessory before the fact
an accomplice who is neither physically nor constructively present during the commission of the crime, but who possesses the requisite intent
- Responsible for the crime and all other crimes that are the natural and probable consequences of the accomplice’s conduct
- To withdraw, an accomplice must:
o Repudiate prior aid,
o Do all that is possible to countermand prior assistance, and
o Do so before the chain of events is in motion and unstoppable.
Accessory after the fact
- Aids or assists a felon to avoid apprehension or conviction after commission of the felony
- Must know that a felony was committed
- Only liable for a separate crime (e.g., “obstruction of justice” or “harboring a fugitive”)
Insanity - M’Naghten
- M’Naghten—D did not know either (i) the nature and quality of the act, or (ii) the wrongfulness of the act, because of a defect of reason due to mental disease (“right from wrong” test)
Insanity - Irresistible impulse
- Irresistible impulse—D lacked capacity for self-control and free choice due to mental disease or defect (inability to conform conduct to the law)
Insanity - Durham
- Durham—the unlawful act was the product of D’s mental disease or defect (“but for” test)
