Defenses Flashcards
Justification
The defendant admits committing the underlying act but asserts that for some reason the act was so socially or morally desirable that it does not fall within the ambit of conduct the criminal law is meant to deter and punish.
See necessity, self-defense, defense of others, and defense of property
Excuse
The defendant admits to behavior satisfying the elements of a crime but argues that he should not be held criminally responsible because of some special circumstance.
Includes duress, entrapment, consent, insanity, and incapacity
Necessity Elements
(1) the defendant committed the crime to prevent an imminent and substantial harm, (2) there was no reasonable alternative course of action available to the defendant, and (3) the harm caused was less than the harm avoided.
Necessity Rules
Actor faced with a clear & imminent danger. Source of harm needs to be natural emergency as opposed to human forces.
Actor must reasonably expect that the action will be effective in abating the danger sought to be avoided. Can only protect persons and property not financial interests.
Harm the actor will cause by breaking the law must be less serious than the harm avoided. Weigh against the harm reasonably foreseeable at the time, rather than the harm that actually occurs.
Actor must have “clean hands.”
Clean Hands
Defendant should not have substantially contributed to the emergency or put herself in a situation where she would be forced to engage in a criminal conduct
Self-Defense
A non-aggressor may use force in self-defense if (1) he actually and reasonably believes (2) that the force is necessary (3) to protect himself from the imminent use of unlawful force by another.
SD Deadly force
only justified in self-protection if the actor reasonably believes that its use is necessary to prevent imminent and unlawful use of deadly force by the aggressor.
SD Reasonable belief
Most jdx: a defendant must reasonably believe that the use of force is necessary to defend against imminent, unlawful force.
First, the defendant must subjectively believe it was necessary to kill to save herself. The focus is on what the defendant perceived when the killing occurred. Second, the defendant’s belief must be objectively reasonable. The focus is on what an ordinary person would have done under the same circumstances.
A reasonable belief can establish the defense even if the belief is incorrect. The minority rule allows the defense even if the defendant unreasonably believed that the use of force was necessary.
SD Imminent Use of Unlawful Force
Force is imminent if it is actually occurring or is about to occur without delay. Preemptive strikes are forbidden.
SD Proportionate Use of Force
The defendant must use no more force than is reasonably necessary to resist another’s use of unlawful force.
SD Duty to Retreat
No duty to retreat ever before using nondeadly force.
Majority Jdx: no duty to retreat ever
Minority jdx: a defendant must retreat before using deadly force if she can retreat with reasonable safety.
SD Castle Doctrine
A defendant has no duty to retreat while inside her home or the areas adjacent or connected to it, unless the defendant is deemed the aggressor. (may extend to the workplace).
Imperfect Self-Defense
Some jurisdictions treat an unreasonable belief that the use of force was necessary as imperfect self-defense. This does not erase criminal liability but it may mitigate the offense of conviction or the sentence. Usually applies where defendant used deadly force when such extent of force was unreasonable and not proportional.
SD Initial Aggressor
An initial aggressor is one who acts so as to create in another person a right of self-defense.
An initial aggressor may not exercise self-defense unless:
The aggressor provokes an altercation using nondeadly force and is met by either the use or imminent threat of deadly force or disproportionate nondeadly force, OR
The aggressor (1) withdraws from conflict in good faith and (2) communicates express or implied notice to the other party of the intent to withdraw.
Key question: who was the aggressor at the time of the deadly injury?
Peterson
Peterson pulled out a gun, so victim picked up a blunt object and walked towards him. He shot him. One cannot support a claim of self-defense by a self-generated necessity to kill.
