justification defenses
Defendant admits responsibility for their acts, but claim they’ve behaved correctly
Typically result in acquittal
excuse defenses
Defendant admits what they did was wrong, but weren’t responsible under the circumstances
e.g. minor, insanity
burden of production
Defendants have to “start matters off by putting in some evidence in support” of their justification or excuse
(i.e. def. have to produce evidence for their defense)
burden of persuasion
If def. meets burden of production, have to prove their defenses by a preponderance of the evidence
perfect defense
Secure a def.’s acquittal
imperfect defense
Secures a lesser sentence for the def.
self-defense
Available for prevention only
Not available to the initial aggressor (Initial Aggressor rule) EXCEPT where the aggressor has withdrawn completely
Four elements:
Unprovoked attack
Necessity
Proportionality (reasonable force)
Reasonable belief
imminent danger (reasonable belief)
Honest and reasonable belief that time for defense is now (subjective)
retreat rule
Person has to retreat unless they honestly and reasonably believe that doing so will not eliminate the threat of death or serious bodily injury
castle doctrine
when you’re attacked in your home you can stand your ground and use deadly force to fend off an unprovoked attack
cohabitant extension: extends castle doctrine further
Been extended in some place to include any place you have a rt to be, protection of property, and against threats that aren’t imminent
→ Creates blanket immunity, shifts burden of proof to prosecutors
stand your ground doctrine
If you don’t start the fight, you can stand your ground and justifiably kill your attacker if you reasonably and honestly believe it’s necessary to do so
Disproportionate force exception: only use enough force to stop the attack (not always lethal force)
necessity
Attack of such a nature that actor must use self-defense to repel it
defense of others
Traditionally meant protecting yourself and members of your immediate family
Has since expanded to include anyone who needs immediate protection from attack
(i.e. not going to get in trouble for trying to stop a fight)
defense of home and property
Extension of rt to self-defense
Often limit use of deadly force to cases where it is reasonable to believe intruders intend to commit violence
*Does not include curtilage*
necessity - choice of evils
Choosing to commit a lesser crime to avoid a greater crime
Life, health, and safety over property, NOT other people (i.e. no cannibalism)
Must be imminent and necessary
Steps:
Identify the evils
Rank them
Choose lesser evils to avoid greatest evil
consent
If a mentally competent adult wants to be a crime victim, gov’t will not get in their way if:
No serious injury
Injury happened during sporting event
Conduct benefits consenting person
Consent is to sex content
Consent is voluntary, knowing, and authorized
insanity
Can be applied to any case where there’s a mens rea element
About 1/3 of these are used in murder cases
Defendants who unsuccessfully argue serve significantly longer
Those acquitted are typically committed to mental institutions and spend twice as long in custody
Only 3% who successfully argue were later diagnosed w/ no mental illness
Only 8% of successful defendants are released from custody after 8 yrs, 35% remain, and 47% remain in monitored custody for life
95% of successful defenses are the product of a plea bargain
Juries biased against this
M’Naughten Rule
A rt-wrong, all-or-nothing test
Depends on def. mental capacity to know rt from wrong
Two requirements:
Def. has mental disease/defect at time of crime
Disease/defect caused def. either not to know nature/quality of actions or that what they were doing was wrong
volitional incapacity
Even if the def. knew what they were doing and knew it was wrong, can qualify for verdict of not guilty if they suffer from mental illness that damages their willpwr or disease was reason they acted
Irresistible impulse
Rely entirely on expert to determine
substantial capacity (MPC)
At time of offense, def. lacked substantial capacity, but not necessarily complete capacity, as a result of mental defect/disease to either:
appreciate wrongness of conduct
conform conduct to requirements of law
*Excludes psychopathic, sociopathic, habitual criminals, antisocial*
*Has to be a defect that affects reason*
Durham Rule (NH)
Traditionally, any crim conduct that’s product of mental illness triggers insanity defense
Now, limited to individuals who must prove legal insanity by clear and convincing evidence
burden of proof for insanity
2/3 of states recognize it is placed upon def., usually by a preponderance
Insanity Defense Reform Act of 1984: holds def. to higher standard, requiring proof by clear and convincing evidence
diminished capacity/responsibility
An attempt to prove def. is guilty of a lesser crime by negating specific intent
(i.e. def. didn’t have capacity to form specific intent)
Purpose drops to knowledge
defense of age
Common law def:
Under 7: no crim capacity
7-14: presumption of no capacity
14+: same capacity as adults
Today:
One type identifies specific age ranges
Another type grants exclusive jurisdiction to juvenile courts up to a certain age but makes exceptions for a list of serious crimes
Third type simply states that juvenile court jurisdiction isn’t exclusive
AR: juvenile court jurisdiction is 17 or younger BUT children under 10 deemed incapable of forming crim intent AND can be treated as adult 14+
duress
Threats amounting to duress - death in some, serious bodily injury in some (AR), some are silent
Immediacy of threats - instant, imminent, unclear in some (AR)
Applicable crimes - some states, not a defense to murder; all crimes in some states; some states don’t say (AR)
Degree of relief - threat real, reasonable belief in others (AR)
intoxication
generally untenable, but two competing principles:
accountability: those who get drunk should face the consequences of their actions
culpability: crim liability and punishment depend on culpability
entrapment
state tries to get you to commit crimes
subjective test: did def. have a disposition to commit, or did intent originate w/ gov’t intervention?
objective test (AR): would the state’s actions cause a normal law-abiding person to commit the crime?
Predisposition doesn’t matter
syndrome
a group of symptoms or signs typical of a disease, disturbance, or condition
defenses that rely on affected mental states
complicity
an actor is liable for someone else’s conduct
accomplice
Before or during crime
Actus reus
Pos. act to help commit
Words not enough (except sometimes if they encourage/approve a crime)
Mere presence at crime not enough unless there’s a duty
Mens rea:
Purposely - clearly qualifies
Knowingly - confusing and split
Recklessness and negligence - more confusing
Common Law punishment: charged like they committed the crime
Modern punishment: same as common law
accessory after
Aiding with awareness of the act
Four elements:
Personally aided
Knew crime was committed
W/ purpose of hindering prosecution
Someone besides accessory committed the crime
Common law punishment: treated as if they committed the crime
Modern punishment: punished less harshly
vicarious liability
Arises when 1 actor is said to have “rt, ability, or duty to ctrl” activities of the violator
Based solely on relationship b/w 2 individuals—principle and agent
Transferred actus reus and mens rea
Punish principle for acts of agent
enterprise vicarious liability
Holding a company responsible for its employees’ actions
Determining their actual responsibility is often difficult b/c there are many stakeholders and decision makers
Common Questions:
Is it fair to stakeholders, who usually end up paying the fine?
Does it have any deterrent effect?
parental vicarious liability
Holding parent responsible for actions of child
Typically violates due process unless parent was negligent, encouraging, etc.
apparent authority
Actor may not have authority in the situation, but does so anyway AND principle is aware and does nothing to stop it
actual authority
Relationship clearly defines agent’s authority and bad act occurred while exercising that authority
inchoate crimes
the mens rea of purpose or specific intent and the actus reus of taking some steps toward accomplishing the criminal purpose—but not enough steps to complete the intended crime
criminal attempt
Two elements:
Intent to commit
Overt act toward commission
criminal attempt actus reus
Dangerous person: even though the act wasn’t complete, we have an interest in stopping dangerous activity before it occurs
Dangerous conduct: even though act isn’t complete, we have an interest in stopping dangerous activity before it occurs
Preparation alone is never enough
proximity test
“Were the defendant’s acts close enough to the intended crime to count as the criminal act in the attempt?”
First have to determine how close is close enough
last proximate act rule
a person is only guilty of an attempt to commit a crime if they perform the final, ultimate act necessary to complete the offense
probable desistance (PD) test
Focus on how much the def. has already done to demonstrate they’re dangerous
Def.’s conduct has to pass pt where most ppl would think better of their conduct and stop
Person test
res ipsa loquitor (a.k.a. unequivocality test)
Does the act speak for itself: if a reasonable person can guess what will happen next, and they draw the conclusion the actor was about to commit a crime, they are guilty of attempt
Person test
dangerous proximity to success test (DPS)
Looking to what def. has left to do to commit the crime
(i.e. has the def. become “dangerously close” to committing the crime)
Conduct test
indispensable elements (IE) test
Has the def. gained ctrl of everything they need to commit the crime?
substantial steps test
Attempters take enough steps toward completing the crime not to show that a crime is about to occur but to prove that the attempters are determined to commit it
Includes:
Lying in wait, searching for, or following the contemplated victim of the crime
Enticing the contemplated victim of the crime to go to the place contemplated for its commission
Reconnoitering [or “casing”] the place contemplated for the commission of the crime
Unlawful entry of a structure, vehicle, or enclosure in which it is contemplated that the crime will be committed
Possession of materials to be employed in the commission of the crime that are specially designed for such unlawful use or that can serve no lawful purpose of the actor under the circumstances
Possession, collection, or fabrication of materials to be employed in the commission of the crime, at or near the place contemplated for its commission, if such possession, collection, or fabrication serves no lawful purpose of the actor under the circumstances
Soliciting an innocent agent to engage in conduct constituting an element of the crime
impossibility
Legal: when actors intend to commit a crime and do everything w/in pwr to, but crim code doesn’t criminalize their actions
Factual: when actors intend and try to commit a crime but some fact or circumstance (extraneous factor) interrupts them to prevent the completion of the crime
abandonment (of crim intent)
Aff def. in 12 states
Unification is aff in AR
Def. abandons his/her attempt
Abandonment prevents commission of offense
Amounts to a voluntary and complete renunciation of his/her crim purpose
conspiracy
Further removed from committing crime than attempt
Justifications for punishing:
Nips crim purpose in the bud
Strikes @ special danger of group crim behavior
Actus reus: agreement to commit a crime
Doesn’t have to be in writing
Unspoken understanding inferred from facts/context is good enough to prove agreement
1/2 of states require overt act to verify firmness of agreement
Mens rea
Specific intent: intent to make agreement or to achieve crim objective
Purpose: difficult to prove
parties to conspiracy
Traditionally: 2+ individuals agree to commit crimes
*Must demonstrate both agreed, can be problematic when undercover*
Unilateral: doesn’t require conspirators to agree w/ or even know other conspirators as long as def. believed there was an agreement
*Failure to convict one party doesn’t preclude conviction of other*
wheel conspiracy
composed of hub (participant in all transactions) and spoke (only participate in one transaction)
chain conspiracy
participants @ one end may know nothing of participants @ other end, but they all handle the same commodity @ one pt (e.g. cartels)
crim solicitation
Trying to get someone else to commit a crime
Requires inciting/encouraging words (approving isn’t enough)
Can solicit an audience
MPC: solicitation doesn’t have to make it to object, though some states do require that
Mens rea: specific intent to accomplish underlying crime
Criminal objective: some felonies, some violent felonies, some “any crime”
AR any felony or misdemeanor
Renunciation qualifies if def. prevented commission of offense solicited by a voluntary and complete renunciation of crim purpose
crim objective for conspiracy
Traditionally: covered everything from treason to disturbing peace
MPC: overt act requirement - act in furtherance of agreement
AR: requires overt act and and mens rea of purpose
Can involve any crim offense
People v. Kimball (‘53)
Drunk guy trying to impress cashier → stages fake robbery → a completed theft is not required for an attempt conviction when actions directly tend toward the crime
State v. Damms (‘60)
mom tries to convince her to stay married → husband kidnaps her → stop at gas station and husband tries to shoot her, but gun isn’t loaded → convicted of attempted murder because all but final act was complete to murder
Le Barron v. State (‘66)
Railroad attempted rape - dude decides not to because she’s pregnant - convicted of attempted rape because his overt acts clearly suggested he intended to rape her
State v. Akers (‘79)
Parents were charged under a statute making them vicariously liable for damages or legal violations caused by their children operating snowmobiles → held that holding parents criminally liable solely based on their parental status is unconstitutional
State v. Chism (‘83)
David dressed as woman, one-legged uncle stabbing of uncle, drive to remote area, he helps hide body, w/in an hour he reports the crime, convicted but Q of why he helped his uncle
