Whether a prisoner charged with escape may invoke the statutory defense of necessity based on threats of sexual assault, physical harm, and death from fellow inmates.
Holding
Yes. Under Illinois's necessity statute, Unger's testimony supplied some evidence from which a jury could find that his escape was necessary to avoid a greater private injury.
Reasoning
Illinois law requires only "some evidence" to raise an affirmative defense. When evidence supports a party's theory, that party is entitled to an appropriate jury instruction presenting it. At the instruction stage, the court does not weigh credibility or resolve conflicts in the evidence.
The court distinguished compulsion from necessity. Compulsion ordinarily concerns a human threat that deprives a person of free will and directs the person to commit the particular charged crime. Necessity instead fits a situation in which a defendant retains a choice but reasonably chooses the lesser of two evils. Unger's account was that he chose escape to avoid actual and threatened sexual assaults and feared lethal retaliation; it was therefore properly analyzed as necessity rather than compulsion.
The statutory necessity defense applies when the accused was without blame in creating the situation and reasonably believed the conduct was necessary to avoid a public or private injury greater than the injury likely to result from that conduct. Unger's testimony about prior threats, a sexual assault, his inability to defend himself, fear that reporting would worsen the danger, and a death threat immediately before he left constituted some evidence of each relevant aspect of that defense.
The State's evidence and Unger's prior statements gave the jury reasons to doubt his motives and the reasonableness of his claimed fear. But those disputes concerned the credibility and weight of the defense, not whether the defense could be submitted to the jury. The jury, rather than the judge, had to decide whether to believe Unger's account.
