Criminal Law (MBE/MEE) Flashcards
Actus Reus
- Either (i) a voluntary, affirmative act, or (ii) an omission (failure to act), causing a criminally proscribed result
- Must be a concurrence of D’s mens rea with the actus reus such that the mens rea causes the actus reus
Voluntary Act
- Must be a physical act that is voluntary (i.e., willed by the defendant/had motor control over the moment)
- Involuntary: Unconscious/asleep/under hypnosis
Failure to Act
A failure to act can constitute the actus reus when a duty exists:
* Imposed by statute (e.g., obligation to file tax return)
* Contract (e.g., lifegaurd saving a drowning person)
* Special relationship (e.g., parent’s duty to her child or duty to one’s spouse)
* Detrimental undertaking (e.g., leaving victim in worse condition after treatment)
* Causation (e.g., failing to aid after causing victim’s peril) (ex. lifeguard failing to save friend after friend had gone swimming based on lifeguard’s assurance that it was safe to do so)
Mens Rea: Specific-Intent
Requires D has a subjective desire, specific objective, or knowledge to accomplish prohibited result. Applicable crimes under common law (FIAT)
* First-degree murder
* Inchoate Crimes (e.g., conspiracy, attempt, solicitation)
* Assault with attempt to commit battery
* Theft Offenses (e.g., larcency, embezzlement, forgery, burglary, robbery)
Mens Rea: Malice
- Requires D acts with a reckless disregard of a high degree of harm.
- Applicable Crimes: Arson and murder
Mens Rea: General-Intent
- Requires the intent to perform an unlawful act
- MPC: Acts done knowingly, recklessly, or negligently
- Applicable Crimes: Battery, rape, kidnapping, false imprisonment, etc.
Transferred Intent
- When D has requisite mens rea for committing a crime against Victim A, but actually commites crime against Victim B, law transfers intent from Victim A over to Victim B.
- Applies only to “bad aim” cases, not mistaken identity
- Does not apply to attempted crimes, only completed crimes (usually homicide, battery, arson)
Mens Rea: MPC
- Purposely
- Knowingly
- Recklessly
- Negligently
MPC: Purposely
D’s conscious objective is to engage in the conduct or to cause a certain result
MPC: Knowingly
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 and acts in a way that grossly deviates from the standard of care of a reasonable person in the situation
Strict Liability
- No mens rea requirement; proof of actus reus is sufficient for conviction
- Generally disfavored; limited to statutory/regulatory offenses (e.g., regulation of food and drugs) and moral offenses (e.g., statutory rape or bigamy)
Vicarious Liability
- Imposes criminal liability on D for the actus reus of a third party
- Corporations may be vicariously liable when act is performed by high-ranking corporate agent who likely represents corporate policy
Mistake of Fact: Common Law
- Specific-intent crimes: Defense to specific-intent crimes, even if unreasonable;
- General-intent crimes: defense to general-intent or malice crimes only if reasonable
Mistake of Fact: MPC
Serves as defense if it prevents P from establishing required state of mind for a material element of offense
Mistake of Law: Common Law
Not valid under common-law; ignorance of the law is no excuse
Mistake of Law: MPC
Only valid under MPC if:
* Reliance on high-level government interpretations;
* Lack of notice of malum prohibitum crimes;
* MIstake of law that goes to an element of specific-intent crime
Principal
- Person whose acts or omissions are the actus reus of the crime
- Must be actually or constructively present at scene of crime
Accomplice
- Person who aids or abets principal prior to or during crime with the intent of assisting the principal to commit the crime
- Liability: Liable for any crimes that are the natural and probable consequences of the accomplice’s conduct
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
Accomplice: Repudiation
To withdraw, an accomplice must:
* Repudiate prior aid,
* Do all that is possible to countermand prior assistance, and
* Do so before the chain of events is in motion and unstoppable
Accessory after the Fact
- A person who aids a felon to avoid apprehension after the felony is committed
- To be guilty, person must know the felony was committed
- Only liable for a separate crime
Insanity: M’Naghten Rule
D did not know either the:
* (i) nature and quality of the act, or
* (ii) wrongfulness of the act
Insanity: Irresistible Impulse Rule
- D lacked capacity for self-control and free choice due to mental disease or defect
- Unable to conform conduct to law
Insanity: Durham Rule
Crime would not have been committed but-for D’s mental disease or defect
Insanity: MPC Rule
D lacked substantial capacity to appreciate the wrongfulness of the act or to conform his conduct to law, as a result of mental disease or defect
Insanity Defense: Constitutional Requirements
- A state is not constitutionally required to recognize any form of an insanity defense
- If a state does recognize an insanity defense, it is constitutionally permissible to shift the burden to the accused to prove it as an affirmative defense
Intoxication: Voluntary
- Person intentionally ingests substance, knowing it is an intoxicant
- Defense (Common-Law): Only to specific-intent crimes if intoxication prevents formation of required mens rea
- Defense (MPC): Defense that require purpose or knowledge, and intoxication prevents formation of that mental state
Intoxication: Involuntary
- Taken without knowledge of intoxicating nature, or under duress
- Defense: Can be valid defense to specific-intent, general-intent, and malice crimes when it negates mens rea necessary for crime
Homicide
- Killing of a living human being by another human being
- Must be actual causation and proximate causation
Homicide: Causation
Actual Causation: But-for causation
Proximate Causation: D’s act is a foreseeable cause of the victim’s death
* Independent actions by a third person are generally not a foreseeable cause, but negligence is generally foreseeable
Common-Law Murder
The unlawful killing of another human being with malice aforethought. Malice can be shown by:
* Intent to kill;
* Intent to do serious bodilly injury;
* Reckless indifference to human life (“depraved heart murder”); or
* Felony murder
