Q

When may the defense of necessity be raised?

A

If the person reasonably believed that commission of the crime was necessary to avoid an imminent and greater injury to society than the crime itself. Good faith belief not enough.

Common law: choice of evils must come from natural forces
Modern: abandoned this requirement

Unavailable where death of a person results from protecting property and where the defendant is responsible for creating the situation requiring a choice between two evils

Q

When is duress available?

A

When, in crimes other than intentional homicide, the defendant reasonably believed that another person would inflict death or great bodily harm on them or their family if they did not comply.

Threats to property traditionally insufficient but allowed by many states and MPC if the value of the property outweighs the harm done to society

Unlike necessity, always involves threat by a human

17
Q

When is mistake/ignorance of fact a defense?

A

Only where it shows the defendant lacked the state of mind required for the crime (unavailable for strict liability crimes)

If offered to disprove specific intent, mistake need not be reasonable, but if offered to disprove general intent, must have been reasonable

18
Q

What is the distinction between mistake of fact and impossibility?

A

Mistake of fact is a defense to a completed crime, usually to negate intent
Impossibility can only occur if the defendant failed to completed the crime

19
Q

When is mistake or ignorance of law a defense?

A

Generally not at all, regardless of whether it was reasonable or based on legal advice

Exception: Defense exists if (1) statute proscribing conduct not available/published prior to conduct, (2) reasonable reliance on a statute or judicial decision, or (3) in some jds, reasonable reliance on official interpretation or advice

Exception: if mistake or ignorance as to collateral legal matter proves lack of required state of mind (must involve elements of the crime but not existence of statute making the act criminal). E.g., cannot be guilty of selling a gun to a known felony if you mistakenly believe the person you sold the gun to had only been convicted of a misdemeanor

20
Q

When is a defense of consent available?

A

Not generally, unless crime requires lack of consent of victim.

Defense to minor assaults and batteries if no serious injury

Requirements if available: (1) consent voluntarily and freely given, (2) legally capable of consent, (3) no fraud in obtaining consent

21
Q

When is a defense of entrapment available?

A

(1) criminal design originated with law enforcement officers
(2) defendant not predisposed to commit crime prior to contact with the government

Cannot be entrapped by a private citizen
