Defenses Flashcards
(45 cards)
Justification
what is it?
denies wrongfulness of particular conduct that would normally constitute an offense.
Society deems that “we would want others to do the same thing in the same or similar situation.”
Excuse
what is it?
conduct is wrongful but circumstances exist such that: (1) a person is not morally blameworthy; or (2) a person could not have been deterred.
Actions that are excused do not involved desirable acts/actions; they are more along the line of understandable acts/actions
What does the MPC do to both excuses and justifications?
MPC combines both!

Justification
Self-Defense rule (SD)
At CL, the D is justified in using force upon another if he reasonably believes he is in imminent danger of death or serious bodily harm by the aggressor
Imminent = right at the moment
Justification
SD Reqs/Elements
To claim the CL SD….
1) D must have been resisting the present or imminent use of unlawful force.
2) D’s force must not be excessive (“proportionality requirement”)
3) D was not the initial aggressor unless:
He was a non-deadly aggressor confronted w/ the unexpected use of deadly force.
and he withdrew after his initial aggression and other party continued
Justification
SD Reqs/Elements
2nd element elaborated
2) Force must not be excessive (“proportionality requirement”)
Deadly force – Force intended to cause death or grievous bodily injury; only use against deadly force of aggressor
Justification
SD Reqs/Elements
3rd element elaborated
3) Aggressor – D can’t be the aggressor unless:
He was a non-deadly aggressor confronted w/ the unexpected use of deadly force.
AND he withdrew after his initial aggression and other party continued
Justification
SD Reasonable Belief to use force (sub element)
A person reasonably but incorrectly believes that the force he uses is necessary to protect
self against imminent harm
–> use of force is justified
Justification
SD
Unreasonable Mistake or Belief
where you D wants to mitigate murder to manslaughter…apply what 2 standards?
Objective Standard and Subjective Standard!
Justification
SD
Unreasonable Mistake or Belief
Objective Standard
Requires the fact finder to view the circumstances surrounding the accused at the time he used force from the standpoint of a reasonable person (standard)
If yes–> then murder mitigated to manslaughter!!
Justification
SD
Unreasonable Mistake or Belief
Subjective Standard
Whether the circumstances are sufficient to induce in the accused an honest and reasonable belief that he must use force to defend himself against imminent harm
If yes–>then mitigates to manslaughter!!!
Justification
SD
Unreasonable Mistake or Belief
Subjective Standard on Battery Wife Syndrome
Creates in the mind in the spouse the feeling that there is no means of escape and turns to what would normally be a reasonable self-defender into a slightly unreasonable one (in the eyes of the jury and others)
Justification
SD
MPC 3.04 SD
Justified if D believes that that force is immediately necessary to protect self against….
the unlawful force of another such as serious bodily harm, death, kidnapping, or sexual intercourse compelled by force or threat
Justification
SD
MPC 3.04 SD Limitations
D has a duty to retreat whenever possible and cannot use deadly force
must use every opportunity to retreat
D cannot be the aggressor
MPC SD cannot be used to resist arrest (even if arrest is unlawful)
D cannot use deadly force to defend home unless owner of property is home (ie. trap gun)
Justification
CL Defense of Others (DofO)
Majority Parallel Doctrine
a right to use defensive force in defense of others if the person believes that the other is in danger of imminent harm.
○ Requires that, if the other person was there, he would have been justified in using self defense.
○ Doctrine also does not consider any special relationship bw the victim and 3rd party D
Justification
CL Defense of Others (DofO)
Minority Jurisdiction rule
Require that the D was factually correct in perceiving that defense was necessary.
Justification
SD
CL Duty to Retreat rule
under the circumstances, a person must safely retreat to avoid killing the aggressor since deadly force is unnecessary
○ Castle Doctrine EXCEPTION: Even when a duty to retreat otherwise exists–> a person is not required to retreat from his/her home or at work
○ Co-habitant EXCEPTION: if you live with a co-habitant that is the aggressor–> then you don’t have a duty to retreat
Justification
Use of force by Law Enforcement
CL General rule
LEO’s are allowed use of whatever force to secure an arrest
some states still use force against any fleeing felon
Justification
Use of force by Law Enforcement
CL specified rule –> However, LEO’s cannot resort to deadly force unless…
they have probable cause to believe that the suspect has committed a felony and poses a threat to the LEO’s or to the public if left at large
* Court also urges police to give a warning prior to use of force. * The force used must also be proportional to the threat posed by the fleeing suspect. ○ The force used must be necessary
Justification
Use of force by Law Enforcement
MPC rule: permits deadly force for law enforcement when….
….necessary to avoid a substantial risk of death or serious injury to innocent persons
most states require a probable cause that the intended victim poses a danger to the LEO or innocent people.
Justification
CL Defense of Real Property
Rule: a person is not entitled to use deadly force….
for the protection of property by using trap guns when the D is not present.
D’s presence at the time of the burglary in his property requires discretion to see whether he can use deadly force
○ However, if a burglary is committed in a violent manner, –> a person may use deadly force.
Justification
Necessity
CL basic rule
the defense raised when D has been compelled to commit a criminal act because of an emergency due to a non-human event (natural force)
