Self Defense w/Deadly Force:

Imperfect self defense is applicable when the D kills another based on good faith belief that (1) they were in imminent danger of being killed or suffering great bodily injury; AND (2) the use of deadly force was necessary to defend against the danger; BUT (3) at least one of those beliefs was unreasonable.
*maybe applied in the defense of others.
Defense of Others
Defenses
A person has the right to defend others under the same circumstances in which self defense would be acceptable. The person would step into the shoes of the other.
General Rule & Rule re: Force
Defense of Property
Defenses
A person in lawful possession of property may take reasonable steps to protect the property.
To use force the person must reasonably believe that the property is in immediate danger of unlawful trespass or immediate danger of being carried away. Force cannot be disproportionate. There is no right to use deadly force in defending property unless the D reasonably believes another intends to commit a felony inside their dwelling.
Types of Tests:
Insanity
Overview
- M’Naughten
- MPC
- Irresistible Impulse
- Durham Test
What burden of proof is required for insanity?
Defenses - Insanity
Federal: Clear and Convicincing in Federal
M’Naghten Test
Defenses - Insanity
D is not guilty if due to a mental disease they did not know either (a) the nature and quality of the act; OR (b) the wrongfulness of the act.
*Assess whether the D’s actions would have been criminal if the facts were as the D believed them to be.
MPC/Substantial Capacity Test
Defenses - Insanity
The D is not guilty if at the time of conduct they did not have substantial capacity to appreciate the wrongfulness of the act or conform their conduct to the law due to the mental disease.
AKA: Combination of the M’Naghten test and Irresistible Impulse test.
Irresistible Impulse Test
Defenses - Insanity
The D is not guilty is they (a) were unable to control their actions or (b) conform their conduct to the law because the mental disease prevented. (Must be an impulse the D cannot resist – does not need to be sudden).
Durham Test
Defenses - Insanity
A D is not guilty if the unlawful act was the product of the D’s mental disease or defect and would not have been committed but for the disease.
Definition:
Voluntary Intoxication
Defenses
Voluntary intoxication is the intentional taking of a substance known to be intoxicating; no intention of actual intoxication is needed.
Voluntary Intoxication - Specific Intent Crimes Rule
Defenses
Voluntary intoxication is a defense to specific-intent crimes if the intoxication prevents the formation of the required intent.
Voluntary Intoxication - MPC Rule
Defenses
Voluntary intoxication is a defense for crimes in which the mental state requires purposely or knowingly and the intoxication prevents the formation of the mental state.
When is Voluntary Intoxication NOT a defense?
Defenses
Voluntary intoxication is not a defense when one does it purposefully to use it as a defense. When the crime involves malice, recklessness, negligence or is a strict liability crime.
Involuntary Intoxication
Defenses
Involuntary intoxication is a defense when the intoxication negates an element of the crimes for general, specific, and malice crimes. Involuntary intoxication occurs when: a substance is taken (a) without knowledge of the intoxicating nature or (b) under duress.
Types of:
Impossibility
Defenses
- Legal Impossibility
- Factual Impossibility
Legal Impossibility
Defenses
Is a defense if the legal impossibility occurs when the D’s acts would not have constituted a crime even if the acts were as the D assumed.
Factual Impossibility
Defenses
Is not a defense to an incomplete crime. Factual impossibility is when the D’s acts would have constituted a crime but for a circumstance or fact unknown to the D.
AKA: if the facts were as D assumed they would have committed a crime
Necessity
Defenses
Necessity is a defense if the D commits a crime due to the forces of nature. However if the D put those forces into action or there is a reasonable non-criminal alternative, then necessity is not a defense.
