Principles of Exculpation and Other Defenses Flashcards
The main categories are:
1) Self-Defense;
2) Defense of a Dwelling;
3) Duress;
4) Necessity;
5) Mistake of Fact;
6) Consent;
7) Entrapment.
A victim may use non-lethal self-defense anytime they
reasonably believe that force is about to be used on them.
Under the majority rule, a victim may use deadly force in self-defense anytime the victim
reasonably believes that deadly force is about to be used on them.
Under the Minority Rule, a victim is required to retreat before using deadly force in self-defense, except:
1) There is no duty to retreat from your home;
2) There is no duty to retreat if you are the victim of a rape/robbery;
3) There is no duty to retreat if you are a police officer.
The original aggressor in a confrontation may claim self-defense IF (3):
1) The original aggressor withdraws;
2) The original aggressor communicates their withdrawal to the other party;
BUT, if the victim escalates a minor confrontation into one involving deadly force (disproportionate defense), without giving the other party the chance to withdraw, the tables are turned.
A defendant may assert the “defense of others” defense if they REASONABLY BELIEVED
that the person they assisted would have had the right to use force in their own self-defense.
Under the Majority Rule there does NOT need to be
a special relationship between a third-party defender and the assisted.
Deadly Force may NEVER be used
to defend property. Property can’t die, as such there is a fundamental problem of proportionality in force.
Duress(pressure from a human force) is a defense to a criminal act if
the defendant acts under the threat of immediate infliction of death/substantial bodily harm AND that belief is reasonable.
Duress is a defense to ALL crimes except
homicide.
Necessity(pressure from natural forces) is a defense if
the defendant reasonably believed their action necessary to prevent a greater societal harm.
Mistake of Fact is a defense only when
the mistake negates intention.
For a general intent or malice crime, the mistake of fact has to be
reasonable.
For a specific intent crime, however, the mistake can be
ANY mistake, no matter how ridiculous, as long as its genuine
Consent of the victim is GENERALLY
not a defense to criminal liability.
