38
Q

Voluntary Manslaughter: Provocation Requirements

(1) Provocation must be objectively adequate: would arouse sudden and intense passion in the mind of a reasonable person (e.g., serious assault or battery; witness adultery)
(2) D was actually provoked (subjective)
(3) D did not have time to cool off (objective)
(4) D did not actually cool off (subjective)

39
Q

Involuntary Manslaughter

A

Two types:
(1) A killing committed during the commission of a crime to which the felony murder doctrine does not apply (misdemeanor manslaughter or unlawful act manslaughter)

(2) Unintentional killing committed:
(a) Common Law: w/ criminal negligence (gross deviation from reasonable standard of care); or
(b) MPC/Modern Trend: recklessly (awareness and conscious disregard of substantial and unjustifiable risk of death)

Thieves Took Carmen’s Purse and Isaac’s Portfolio

Requirements:

(1) Trespassory: wrongful or unlawful
(2) Taking and Carrying away: property must be moved
(3) Personable property of Another: who had lawful custody/possession at time of taking?
(4) Intent to Permanently Retain the Property: if D intends to give back, lacks necessary intent to steal

45
Q

Larceny: Erroneous Takings Rule

A

A taking under a claim of right is never larceny, even if D erroneously believes the property is his

46
Q

Larceny: Continuous Trespass

A

If D wrongfully takes property w/o intent to steal, but later forms that intent, the initial trespasspory taking is considered to have “continued” and D will be guilty of larceny

(Exception to concurrence principle)

47
Q

Embezzlement

A

Definition: Conversion of the personal property of another by a person already in lawful possession of that property with the intent to defraud

Mental state: specific intent to defraud

Distinguish from larceny because D has lawful possession

Possession involves more than mere custody – requires authority to exercise some discretion over the property

48
Q

False Pretenses

A

Definition: Obtaining title to the personal property of another by a false statement made knowingly with the intent to defraud

Distinguish from larceny: D gets only custody of property; false pretenses, D gets title

49
Q

Larceny by Trick

A

If D only obtains custody (not title) as a result of false statement, crime is larceny by trick not false pretenses

50
Q

Elements: (1) A larceny (2) from someone else’s person or presence (3) by force or threat of immediate injury.

Mental state: specific intent to steal

51
Q

53
Q

Forgery

A

Making or altering a writing so that it is false

Mental state: specific intent to defraud

54
Q

MPC Theft

A

MPC and most states have consolidated common law property crimes of larceny, embezzlement, false pretenses, and larceny by trick into a single offense typically known as theft

Under this statutory approach, seriousness of the crime is determined by the value of the property taken

55
Q

Common Law Burglary

A

(1) Breaking and (2) entering the (3) dwelling of (4) another (5) at night (6) with the intent to commit a felony inside

(1) Breaking: creating/enlarging an opening by at least minimal force; constructive breaking: entry gained through fraud, threats, or intimidation
(2) Entry: some part of D’s body must enter the building
(3) Dwelling: structure where someone regularly sleeps
(4) Of another: cannot burglarize your own house
(5) At night
(6) Intent to commit: specific intent crime (e.g. rape, rob, kill, assault)

56
Q

MPC Burglary

A

Many states have eliminated technical common law requirements: breaking, dwelling, nighttime

57
Q

Common Law Arson

A

Malicious burning of the dwelling of another

Mental state: malice

Burning: (1) requires material wasting (e.g. scorching insufficient) and (2) building itself must burn

58
Q

Moder Statutory Arson

A

Under MPC and in most states, arson has been extended to include structures other than dwellings and to damage caused by explosion

59
Q

Possession of Contraband

A

When a statute criminalizes the possession of contraband, possession means control for a period of time long enough to have an opportunity to terminate possession
-Constructive possession: close enough for D to exercise dominion and control over it

Mental state: knowledge of possession and character of item possessed

60
Q

Receipt of Stolen Property

A

(1) Receiving possession and control (2) of stolen personal property

Mental state: (1) Knowledge that the property has been obtained criminally by another party and (2) with the intent to permanently deprive the owner of his interest in the property

61
Q

Principal

A

Person who commits the crime

62
Q

Accomplice

A

Person who helps:

(1) Acts (aids or encourages the principal)

(2) Mental state: intent to assist the principal and with the intent that the underlying crime be committed
- Recklessness and negligence crimes: If principal’s mental state is R or criminal/gross N, accomplice liable for “intentional conduct that aids the principal and manifests the required recklessness or negligence”

63
Q

Accomplice Liability

A

Rule: The accomplice is guilty of (1) all the crimes he aided or encouraged and (2) all other foreseeable crimes committed along with the aided crime

Not an accomplice if (a) mere presence or (b) mere knowledge

64
Q

Accomplice Liability - Withdrawal

A

An accomplice can avoid criminal liability by withdrawing before the crime is committed. What he must do to withdraw depends on how he assisted the principal:

Encourager: withdraw by repudiating encouragement before crime committed

Aider: must neutralize assistance or otherwise prevent crime from happening

65
Q

Accessory After the Fact

A

Common law: D must (1) help principal who committed a felony (2) with knowledge that the crime has been committed and (3) with intent to help the principal avoid arrest or conviction

Modern: in many jurisdictions, separate statutory crimes for accessories after the fact, e.g. obstruction of justice, harboring a fugitive, hindering prosecution

66
Q

Enterprise Liability

A

General rule: when a corporate agent engages in criminal conduct, the corporation and the agent may be held criminally liable, if agent is acting (1) on behalf of corporation and (2) within the scope of his/her office

Public welfare offenses: when corporation commits a regulatory offense involving public health or safety, agents can be held criminally liable if the stand in “responsible relation to the situation” that created the public danger

67
Q

Inchoate offense: Solicitation

A

Asking someone to commit a rime with the intent that the crime be committed

Mental state: specific intent

Completion of the crime is unnecessary; whether the other person agrees is irrelevant

68
Q

Inchoate offense: Conspiracy

A

An agreement between two or more people to commit a crime plus an overt act in furtherance of the crime
-Agreement: express or proved by conduct (concert of action towards a common goal)

Mental state: specific intent to (1) enter into an agreement and (2) to accomplish the objectives of the conspiracy

Bilateral approach: need at least 2 people; if other parties acquitted, sole remaining D cannot be convicted
MPC approach: one person alone can be convicted of conspiracy even if others were acquitted or just pretending to agree

Impossibility is not a defense

69
Q

Conspiracy - Wharton Rule

A

When 2 or more people are necessary for the crime, conspiracy only occurs when more people than necessary to commit the crime are in agreement

70
Q

Conspiracy - Vicarious/Pinkerton Liability

A

In addition to conspiracy, D will be liable for crimes committed by co-conspirators as long as: (1) those crimes were committed in furtherance of the conspiracy’s objective and (2) were foreseeable

71
Q

Inchoate offense: Attempt

A

Required acts: (1) overt act beyond mere preparation (cf. conspiracy) – (a) Common law: D must engage in conduct dangerously close to commission; (b) MPC/Majority: D must engage in substantial step towards commission that strongly corroborates actor’s criminal purpose

Mental state: specific intent to commit the underlying crime
-So, not attempt for unintentional crimes, i.e. recklessness crimes, negligence crimes, felony murder

72
Q

Inchoate offenses: Withdrawal / Renunciation / Abandonment

A

Withdrawal is not a defense

Exception: once D withdraws from conspiracy, he is not longer vicariously liable from co-Ds’ crimes committed after he left BUT still guilty of conspiracy and all foreseeable crimes prior to withdrawal

73
Q

Inchoate offenses: Merger Rules

A

(1) Solicitation and attempt merger with the completed crime

(2) Conspiracy does not merger

74
Q

Defenses: Insanity

A

D must have a mental disease or defect - at the time of the crime

(1) Majority - M’Naghten Test: D must prove he either (a) did not know his conduct was wrong or (b) did not understand the nature of his conduct
(2) Minority - MPC: D must establish he lacked the substantial capacity to either (a) appreciate the criminality of his conduct or (b) conform his conduct to the requirements of the law

75
Q

Incompetency

A

The issue is whether, at the time of trial, the D cannot either: (a) understand the nature of the proceedings against him or (b) assist his lawyer in the preparation of his defense

If (a) or (b) is found, trial is postponed until D regains competency

76
Q

Defenses: Voluntary Intoxication

A

Common law approach: can be a defense to specific intent crimes but not to malice, general intent or strict liability crimes

Generally requires such severe “prostration of the faculties” that D cannot form the requisite specific intent

77
Q

Defenses: Infancy

A

Common Law (Rule of Sevens):

(a) If at time of crime D is younger than 7, no prosecution allowed
(b) If at time of crime D is younger than 14, rebuttable presumption against prosecution
(c) If at time of crime D is 14 or older, prosecution is allowed

78
Q

Defenses: Mistake of Fact

A

Common law: Whether D’s mistake of fact will be a defense depends on mental state for the crime and whether the mistake is reasonable or unreasonable

Specific intent: any mistake of fact (reasonable or unreasonable) will be a defense

Malice or general intent: only a reasonable mistake of fact will be a defense

Strict liability: mistake of fact will never be a defense

IN other words: a reasonable mistake of fact is a defense to all but strict liability; an unreasonable mistake of fact is only a defense to specific intent

79
Q

Defenses: Mistake of law

A

Mistake of law is generally not a defense

Exception: if the statute specifically makes knowledge of the law and element of the crime

80
Q

Defenses: Self-Defense (Justification) - Non-deadly Force

A

Individual may use non-deadly force in self defense if he is without fault and:
(1) reasonably believes that doing so is necessary (2) to protect himself from the imminent use (3) of unlawful force upon himself

81
Q

Defenses: Self-Defense (Justification) - Deadly Force

A

Individual can use deadly force in self-defense only if (1) he is confronted with unlawful force, (2) is without fault, and (3) reasonably believes he is facing an imminent threat of death or serious bodily harm

Deadly force cannot be used to defend property

82
Q

Defenses: Initial Aggressor Rule

A

A D may not use force in self-defense if he is the initial aggressor, BUT he can regain the right to use force in self defense if (1) he withdraws from the fight and communicates withdrawal to other person; OR (2) the victim suddenly escalates a nondeadly fight into a deadly one

83
Q

Defenses: The Retreat Rule

A

In some states, D is required to retreat before using deadly force in self-defense

(a) Majority rule: retreat is not required
(b) Minority rule: retreat is required, unless (i) D cannot retreat in complete safety or (ii) D is in his home

84
Q

Defenses: Self-Defense, Reasonableness, and Mistake

A

If D is mistaken about need to use force:

(1) Reasonable mistake: complete defense
(2) Unreasonable mistake: (a) Majority rule: no defense at all; (b) MPC/Minority rule: mitigates but does not exonerate

85
Q

Defenses: Use of Force to Prevent a Crime

A

(1) Non-deadly force may be used, if reasonably necessary, to prevent any serious breach of the peace
(2) Deadly force may only be used to prevent a felony risking human life

86
Q

Defenses: Defense of Property

A

Deadly force may not be used to defend property

87
Q

Defenses: Use of Deadly Force by Law Enforcement

A

An officer may use deadly force only when doing so is reasonable under the circumstances

88
Q

Defenses: Necessity (Justification)

A

Conduct that is otherwise criminal is justifiable if D reasonably believed it was necessary to prevent a greater harm

Defense not available if

(1) D causes the death of another person to protect property
(2) D is at fault in creating the situation that creates the choice of evils

89
Q

Defenses: Duress

A

It is a defense to criminal conduct if D was coerced to commit a crime because of (1) a threat (2) from another person (3) of imminent death or serious bodily injury (4) to himself or a close family member

*Cannot be a defense to intentional homicide

90
Q

Defenses: Entrapment

A

If D believes the government unfairly tempted him to commit a crime, he may claim entrapment

Majority Test (Subjective): D must prove (1) the criminal design originated with the government and (2) he was not predisposed to commit the crime

Minority Test (Objective): D must prove police activity was reasonably likely to cause an innocent person to commit the crime (D’s predisposition is irrelevant)

91
Q

Attempted Murder - Mens Rea

A

In order to be convicted of attempted murder, D must have intent to kill

The following are not sufficient mens rea for attempted murder: malice aforethought, intent to inflict great bodily injury, intent to commit a felony, awareness of an unjustifiably high risk to human life
