| Question | Answer |
|---|---|
| Elements of a crime | Prima Facie Case: Actus Reus + Mens Rea + Concurrence + Causation |
| Actus rea | voluntary affirmative act or a failure to act when a legal duty exists. |
| legal duty exists | statute or law requires, relationship between the defendant and the victim, contract obligate, defendant voluntarily assumes a duty and excludes others from helping; or (5) The defendant created the risk of harm, whether or not the defendant was at fau |
| Mens rea | required mental state of mind. |
| MR:CL | General Intent: Crimes that require the intent to commit the actus reus, but not the result. o Specific Intent: Crimes that require a specific state of mind related to the resulting crime |
| MR:MPC | Purposely:. o Knowledge: o Willful Blindness: o Recklessness: o Negligence: |
| MRR:MPC: Purposefully | The defendant’s conscious or primary objective was to cause the relevant harm |
| MR:MPC: Knowledge | defendant was practically certain that the harm would result. |
| MR:MPC: Willful Blindness | mental state for knowledge is satisfied if the defendant was reckless and took deliberate steps to avoid learning the truth. |
| MR:MPC: Recklessness | defendant was aware of a substantial and unjustified risk that the harm would occur; the risk must be significant and not warranted under the circumstances. |
| MR:MPC: Negligence | defendant’s failure to perceive a substantial and unjustified risk that the harm would occur was a substantial deviation from the standard of care. |
| Transfered intent | CL and the MPC, a defendant’s intentional mens rea can transfer to an unintended victim if the defendant’s actus reus resulted in the same or similar crime as the intended crime; transferred intent only applies to completed crimes, not attempted crime |
| Strict Liability | Crimes that require no mens rea. |
| Vicarious Liability | efendant can be responsible for the actions of another under the theories of conspiracy liability, accomplice liability, and felony murder. |
| Concurrence | e defendant must have the required mens rea at the time the defendant acts |
| causation | or completed crimes, the defendant’s act must be the actual and proximate cause of the victim’s harm; this is not required for inchoate offenses. |
| Actual cause | he defendant’s act must be the but-for cause of the harm or be a substantial factor in producing the harm. |
| Proximate Cause | e harm was the direct and natural result of the defendant’s actus reus |
| Intervening events | If an event occurs between the defendant’s act and the eventual harm, the event becomes a superseding cause that breaks the causal chain if the event was not foreseeable |
| Homicide | |
| Common Law Murder | nlawful killing of another human- satisfied if the defendant has one of the four mental states: (1) intent to kill, (2) intent to inflict serious bodily harm, (3) extreme recklessness (depraved heart murder), or (4) felony murder. |
| intent to kill | Requires the defendant (1) to have the conscious objective or purpose to cause death or (2) be substantially certain the death would result. |
| Extreame Recklessness | Requires the defendant to (1) be consciously aware of a substantial and unjustified risk that the death will result from the defendant’s actions, and (2) engage in behavior that exhibits a complete lack of care for human life. |
| Felony Murder | Applies if five requirements are met: |
| FM: | Five requriments - during, mens rea for underlying felony, inherently dangerous, independta, forseeable- agency or proximate cause |
| first degree | 1) An intentional killing with premeditation and deliberation, or (2) a killing that occurs during the commission of an inherently dangerous felony. |
| Second-degree | (1) An intentional killing without premeditation or deliberation, (2) an unintentional killing in which the defendant had intended to inflict serious or great bodily harm, or (3) depraved heart murder. |
| voluntary manslaughter | A killing (1) done in the heat of passion or (2) resulting from an imperfect use of self-defense. heat of passion |
| VM: imperfect self-defense | Occurs when either (1) the defendant feared imminent harm, but that fear was not reasonable; or (2) the defendant’s use of deadly force to prevent the harm was disproportionate |
| Involuntary Manslaugther | An unintentional killing that occurs (1) when the defendant recklessly or negligently causes the death or (2) during the commission of an unlawful act that does not qualify as an inherently dangerous felony recklessness- actually aware v. negligent-sh |
| MPC | |
| Murder | ncludes (1) all intentional killings, regardless of whether they were committed with premeditation and deliberation; and (2) killings done with extreme indifference, which include unintentional killings that occur during the commission of a felo |
| Manslaughter | es (1) killings done with recklessness and (2) killings under extreme mental or emotional disturbance for which there is a reasonable justification or excuse. |
| Negligent omicide | killing done with criminal negligence |
| Larceny | (1) trespassory (i.e., unlawful) (2) taking and carrying away (3) of the personal property of another (4) with the intent to steal |
| L: Taking and carrying away | Requires some movement of the property away from its origin; applies if the defendant designates an agent to pick up the property. |
| L: Continuing trespass doctrine | a defendant’s initial conduct constitutes a trespassory taking and carrying away of property without the intent to steal it, but the defendant thereafter forms the requisite intent, the defendant will still be guilty of larceny |
| Larcey by trick | Includes the four elements of larceny but also requires an additional element: (5) the theft must be accomplished by the defendant’s fraud |
| Robbery | ncludes all four of the requirements of larceny and (5) the theft must be accomplished by use of actual physical force or the threat of force, and (6) the taking must be from the victim or the victim’s presence |
| False pretenses | 1) The defendant makes a fraudulent statement that (2) results in the victim passing title in the property to the defendant. |
| embezzlement | (1) The defendant is in lawful possession of another’s property (i.e., tangible or intangible) and (2) the defendant fraudulently converts the property to the defendant’s own use (3) with the intent to permanently deprive |

| Battery | Causing another person an unlawful harmful or offensive contact (acting with at least recklessness or criminal negligence). |
| Rape | person commits rape when the person engages in (1) sexual intercourse (2) by force or the threat of force (3) without consent. (4) The state of mind required is recklessness or criminal negligence with respect to the victim’s consent |
| R: Sexual intercourse | At CL, this meant only vaginal intercourse; today, it means any kind of penetration (i.e., vaginal, oral, or anal). |
| R: Force or threat of force | At CL, considerable force was required; today, most jurisdictions only require a small amount of force. |
| R: Alternatives to force | force not required if the victim is intoxicated or unconscious; some include psychological or extreme emotional coercion; and a few jurisdictions have eliminated the force requirement and focus solely on consen |
| R: Without Consent | Consent can be conveyed verbally or through actions. A victim may be legally incapable of giving consent due to a mental deficiency or intoxication. The more force used, the stronger the inference is that the victim did not consent |
| R:fRAUD | If the defendant engaged in fraud in the factum then consent is not effective; but consent is effective if there was fraud in the inducement |
| Statutory Rape | erson commits statutory rape when the person has (1) sexual intercourse with (2) another person under the age of consent. In many jurisdictions, statutory rape is a strict liability crime, so it does not matter whether the defendant was aware of the age |

| Intox: Involuntary | Applies if the defendant was unwittingly drugged or otherwise intoxicated against the defendant’s will where the effect was powerful enough to defeat the mens rea requirement. |

| Duress | elieved that (1) the defendant or another person faced an ongoing threat of death or serious bodily harm, and (2) the defendant could prevent the threatened harm only by carrying out the unlawful action with which the defendant is charged. |
| Duress: CL Exception | Duress is not a defense to intentional killings or when the defendant was responsible for creating the situation. |
| Duress: MPC | Duress is a defense to intentional killings and does not require the threat to be immediate or imminent, only that a reasonable person could not have resisted it. |
| Mistake of fact | not a defense, but the mistake of a material fact can negate the mens rea requirement |
