Common Law Mens Rea (mental state)
(1) Specific Intent
(2) Malice
(3) General Intent
(4) Strict Liability
Common Law Mens Rea: Specific Intent
Desire to do the act and achieve a specific result
11 specific intent crimes: (1) assault, (2) first degree murder, (3) larceny, (4) embezzlement, (5) false pretenses, (6) robbery, (7) forgery, (8) burglary, (9) solicitation, (10) conspiracy, (11) attempt
Defenses: (a) voluntary intoxication; (b) mistake of fact
Common Law Mens Rea: Malice
When a defendant acts intentionally or with reckless disregard of an obvious or known risk
Malice crimes:
(1) Murder
(2) Arson
Common Law Mens Rea: General Intent
The defendant need only be generally aware of the factors constituting the crime; he need not intend the specific result
General intent crimes: (1) Battery, (2) Forcible rape; (3) False imprisonment; (4) Kidnapping
Common Law Mens Rea: Strict Liability
When the crime requires simply doing the act, no mental state is required
Types of SL crimes:
(1) Public welfare offenses: regulatory offenses that implicate public health or safety and typically carry small penalties
(2) Statutory rape
Model Penal Code Mens Rea (mental state)
Five mental states:
(1) Purpose
(2) Knowledge
(3) Recklessness
(4) Negligence
(5) Strict Liability
Model Penal Code Mens Rea: Purpose
D acts purposely when it is his conscious desire to achieve a particular result
Model Penal Code Mens Rea: Knowledge
D acts knowingly when he is aware of what he is doing and is aware that the result is practically certain
Model Penal Code Mens Rea: Recklessness
D acts recklessly when he is aware of a substantial and unjustifiable risk, and consciously takes that
Model Penal Code Mens Rea: Negligence
D acts negligently when he should have been aware of a substantial and unjustifiable risk
Model Penal Code Mens Rea: Strict Liability
No mental state required
Causation
Need (1) actual causation and (2) proximate/legal causation
Actual Causation
D is an actual cause if the bad result would not have occurred but for the defendant’s conduct
-Exception: when an accelerating cause is an actual cause
Legal/Proximate Causation
D is a proximate cause if the bad result is a natural and probable consequence of D’s conduct
(a) Intervening causes: D not considered proximate cause if unforeseeable event causes the bad result
(b) Eggshell victims: D will be considered proximate cause even if victim’s preexisting weakness contributed to the bad result
Concurrence Principle
D must have the required mental state at the same time he engages in the culpable act
Most frequently arises in: larceny and burglary
Battery
(1) The unlawful application of (2) force to another (3) resulting in either (a) bodily injury or (b) an offensive touching.
Mental state: general intent
Assault
(1) Attempted battery
OR
(2) Reasonable apprehension: (a) the intentional creation, (b) other than by mere words, (c) of a reasonable apprehension in the mind of the victim (d) of imminent bodily harm (e.g. fake punch)
Mental state: specific intent
Homicide: Year and a Day Rule
Majority rule: death may occur at any time
Common law rule: death must occur within a year and a day of the homicidal act
Murder
(1) The unlawful killing (2) of another person (3) with malice aforethought
Mental state: malice aforethought, satisfied by any of the below:
(a) Intent to kill
(b) Intent to inflict serious bodily harm
(c) Extreme recklessness (reckless indifference to human life)
(d) Intentional commission of an inherently dangerous felony (felony murder)
Deadly Weapon Rule
The intentional use of a deadly weapon creates an inference of an intent to kill
Deadly weapon: any instrument used in a manner likely to produce death or serious bodily injury
Transferred Intent
If a D intends to harm one victim, but accidentally harms a different victim instead, the D’s intent will transfer from the intended victim to the actual victim
Applies most commonly to murder, but can apply to other crimes (e.g. battery and arson)
Exception: Transferred intent does not apply to attempts, only to completed harms
Degrees of Murder
First degree murder: any killing committed with (a) premeditation (forethought) and (b) deliberation (cool, calm, collected)
Second degree murder: all other intentional murders (including depraved heart murder, intent-to-do-serious-bodily-harm murder)
Felony Murder
Any killing caused during the commission of or attempt to commit a felony
Felony Murder: Common Limitations
(1) D must have committed the underlying felony
(2) Felony must be inherently dangerous (e.g. burglary, robbery, rape, arson, kidnapping)
(3) Merger rule: felony must be independent of the killing (e.g. underlying crime cannot be aggravated assault or battery)
(4) Res gestae principles: killing must take place during the felony or during immediate flight from the felony – once felon reaches temporary safety, felony ends
(5) Death must be foreseeable
(6) Victim must not be a co-felon
Felony Murder: Vicarious Liability
Proximate cause theory: In some states, if one co-felon proximately causes the victim’s death, all of the other co-felons will be guilty of felony murder, even if the actual killing is committed by a third party
Agency theory: In other sates, felony murder doctrine applies only if the killing is committed by one of the co-felons
