Defenses Flashcards
Two categories of defenses
Case in Chief & Affirmative
Case in Chief Defense:
what does the D argue?
D attacks the prosecution’s case in chief by arguing that the prosecutor has failed its burden of proof on at least one essential element of the crime
Can attack mens rea, actus reus, causation, or concurrence
D only needs to raise a reasonable doubt as to the existence of one element to secure a complete acquittal
Affirmative Defenses:
What does D argue?
Who has burden of proof?
Two types of affirmative defenses?
D admits the state has met its burden of proof regarding the case in chief, but argues that the D nonetheless should be acquitted for some other reason
D bears the burden of proof
Traditionally characterized as either justification defenses or excuse defenses
Two types are Justification and Excuse defenses
Justification Defenses in General
What are they?
What do they focus on?
A justification defense deems conduct that is otherwise criminal to be socially acceptable and non-punishable under the specific circumstances of the case.
Justification focuses on the nature of the conduct under the circumstances.
What are the six types of justification defenses
- Self Defense:
- Imperfect Self Defense:
- Defense of Others
- Defense of Habitation
- Defense of Property
- Necessity
Common Law
Self Defense Elements and Requirements
Elements:
D must have had an honest and reasonable belief that:
- Imminent threat of unlawful force, AND
- That the force D used was both:
a. Necessary - to repel the threat AND
b. Proportional - to the threat, use of force cannot be excessive in relation to the harm threatened
Three Additional Requirements:
- Imminence requirement
- Necessity requirement
- Proportionality requirement
MPC Self Defense
A person is justified in using such force as is immediately necessary to repel or prevent the use of unlawful force against them
D Believes force is immediately necessary to protect himself or others
Belief need not be reasonable (but MPC has a general reasonableness component)
MPC Self Defense:
Use of Deadly Force
Deadly force is ok to protect from death, serious bodily injury, forcible rape, kidnapping
Deadly force not ok if you started it with deadly force or you are/become the aggressor
Use of Deadly Force/Retreat: Cannot use deadly force against aggressor if D can avoid by retreating to complete safety
Imperfect Self Defense
Definition
D honestly but unreasonably believe that force was necessary but actually was not, no purposeful mens rea
Imperfect Self Defense:
Traditional CL
Modern Common Law
MPC
- Traditional CL: if the victim dies, D is convicted of murder
- CL: Offense gets downgraded, honest belief
- MPC: offense gets downgraded if not purposefully or knowingly but not if negligently or recklessly
Purpose or reckless negates the lack of mens rea
If actor is reckless or negligent in having a belief about the necessity of that force under the circumstances, or when the actor is reckless or negligent in acquiring knowledge about the justifiability of her use of force, no justification defense is available
Defense of others:
Common Law, Traditional v. Modern
Traditional CL: person is justified in using force to protect a third party from unlawful use of force by an aggressor to the extent that the third party is justified in acting in self defense,
Traditional CL required that the third party actaully would have been justified in using self defense.
Modern CL: person is justified in using force to protect a third party from unlawful use of force by an aggressor to the extent that the thrid party is justified in acting in self-defense,
Today, majority view is that the use of force may be justified if it reasonably appears necessary for the protection of the third party
Defense of Others:
MPC - 3 Factors
- He uses no more force to protect the third-party than he would be entitled to use in self-protection, based on the circumstances as he believes them to be;
- Under the circumstances as he believes them to be, the third party would be justified in using such force in self-defense; and
- He believes that intervention is necessary for the third party’s protection.
Defense of Habitation:
Early CL
Modern CL
Other CL Jurisdictions
Early Common Law:
• Permitted an occupant to use any force necessary including deadly force if he reasonably believed the force was necessary to prevent an imminent unlawful entry
Modern Common Law:
• Modified original rule to restrict use of deadly force to cases in which the occupant reasonably believes such force is necessary to prevent imminent unlawful entry AND
• The intruder intends to commit a felony or cause injury to the occupant or another occupant of the dwelling
Other CL Jurisdictions:
• Occupant can use deadly force only if he reasonably believes that such force is necessary to prevent imminent unlawful entry AND
• That the intruder intends to commit a forcible felony OR kill OR cause grievous bodily injury to the occupant or another occupant
• Described as a kind of “accelerated” self-defense or defense of others
Defense of Habitation:
Castle Doctrine generally
• In some jurisdictions, a person protecting his abode may stand his ground (instead of retreating) and use deadly force against an intruder (or an invited guest) who intends to commit an armed robbery and/or inflict serious bodily harm upon the person or upon those in the property.
Defense of Habitation
Castle Doctrine:
Reasonable Expectation Test
Focuses on the protection the inhabitants of a structure reasonably expect
Court says an open window or door provides some expectation of protection bc reasonable people understand that portals may not be crossed without permission by the owner
