Criminal Law Flashcards
General Principles
(Criminal Law)
- Actus Reus
- Mens Rea
- Parties to Crime
- Responsibility
Actus Reus
(General Principles)
- voluntary, affirmative act, OR
- omission (failure to act), causing a criminally proscribed result
Voluntary Act
(Actus Reus)
- Physical and voluntary
- Unconscious/asleep/under hypnosis—not voluntary
Failure to act when duty exists
(Actus Reus)
- 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
(General Principles)
a guilty mind or legally proscribed mental state (no mens rea for strict liability crimes)
Specific Intent (SI) Crimes
(Mens Rea)
Defendant (D) has a subjective desire, specific objective, or knowledge to accomplish prohibited result (FIAT):
1. First-degree murder
2. Inchoate offenses
3. Assault with intent to commit battery
4. Theft offenses
Malice Crimes
(Mens Rea)
- Reckless disregard of a high risk of harm
- Requires only a criminal act without excuse, justification, or mitigation
- Intent can be inferred from the accomplishment of the act
(e.g., CL murder, arson)
General Intent Crimes
(Mens Rea)
Require the intent to perform an unlawful act
(e.g., battery, rape, kidnapping, and false imprisonment)
Intent
(General Intent Crimes)
- purposely,
- knowingly,
- recklessly, OR
- negligently
Transferred Intent
(General Intent Crimes)
- 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
- Applies only to “bad aim” cases (not mistaken identity)
- Usually confined to homicide, battery, and arson
- Not for attempted crimes (only completed crimes)
- 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
Model Penal Code
(Mens Rea)
- Purposely—D’s conscious objective is to engage in the conduct or to cause a certain result
- Knowingly/willfully—D is aware or knows that the result is practically certain to occur based on his conduct
- Recklessly—D acts with a conscious disregard of a substantial and unjustifiable risk 4. Negligently—D should be aware of a substantial and unjustifiable risk that a material element of a crime exists or will result from his conduct (i.e., a gross deviation from the standard of care)
Strict Liability Claims
(Mens Rea)
- 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
(e.g., statutory rape, bigamy, regulation of food and drugs)
Vicarious Liability
(Mens Rea)
- 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
(Vicarious Liability)
may be vicariously liable when the act is performed by a high-ranking corporate agent who likely represents corporate policy
Causation
(Mens Rea)
D’s mens rea (if required) must cause the actus reus, and the act must cause the particular result made unlawful by statute
Mistake as Defense
(Mens Rea)
Mistake of fact:
1. May negate criminal intent (if an “honest mistake”)
2. A defense to specific-intent crimes, even if unreasonable
3. A defense to general-intent or malice crimes, only if reasonable
Mistake of law—only valid if:
1. D relied on court decision/ administrative order or official interpretation,
2. Statutory definition of malum prohibitum (illegal by statute) crime not available before conduct, OR
3. An honestly held mistake of law negates required intent or mental state
Parties to Crime
(General Principles)
- Principal
- Accomplice Liability
- Accessory after the fact
Principal
(Parties to Crime)
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 Liability
(Parties to Crime)
- Accomplice, Principal in the second degree, Accessory before the fact
- Responsible for the crime and all other crimes that are the natural and probable consequences of the accomplice’s conduct
Accomplice
(Accomplice Liability)
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
(Accomplice Liability)
accomplice who is physically or constructively present during the commission of the crime
Accessory before the fact
(Accomplice Liability)
accomplice who is neither physically nor constructively present during the commission of the crime, but who possesses the requisite intent
Withdrawal
(Accomplice Liability)
To withdraw, accomplice must:
1. Repudiate prior aid,
2. Do all that is possible to countermand prior assistance, AND
3. Do so before the chain of events is in motion and unstoppable
Accessory after the Fact
(Parties to Crime)
- 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”)
Responsibility
(General Principles)
- Insanity
- Intoxication
Insanity Tests
(Responsibility)
- M’Naghten
- Irresistible impulse
- Durham
- MPC
M’Naghten Test
(Insanity)
D did not know either:
1. the nature and quality of the act, OR
2. the wrongfulness of the act, because of a defect of reason due to mental disease (“right from wrong” test)
Irresistible Impulse Test
(Insanity)
D lacked capacity for self-control and free choice due to mental disease or defect (inability to conform conduct to the law)
Durham Test
(Insanity)
unlawful act was the product of D’s mental disease or defect (“but for” test)
MPC Test
(Insanity)
at the time of the conduct, 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
(combines M’Naghten and irresistible impulse)
Voluntary Intoxication
(Responsibility)
- Intentional taking of a substance known to be intoxicating
- Need not intend actual intoxication
- A defense to SI crimes if it prevents the formation of the required intent
- MPC— a defense to crimes with a mental state that is “purposely” or “knowingly” and the intoxication prevents the formation of that mental state
Involuntary Intoxication
(Responsibility)
- Taken without knowledge of the intoxicating nature, or under duress
- A defense when intoxication negates an element of a general intent, specific intent, or malice crime; may be a defense to a strict liability crime by negating the voluntary act
Homicide

the killing of a living human being by another
Murder
(Homicide)
the killing of a living human being by another
Malice
(Murder)
can be shown by any one of the following:
1. Intent to kill
2. Intent to do serious bodily injury
3. Reckless indifference to human life
4. Intent to commit a felony
Intent to Kill
(Malice)
conduct that is the legal cause of death + intent to kill
Intent to do serious bodily injury
