Sec. 2.03. Defense

A defense to prosecution for an offense in this code is so labeled by the phrase: "It is a defense to prosecution...."

The prosecuting attorney is not required to negate the existence of a defense in the accusation charging commission of the offense.

The issue of the existence of a defense is not submitted to the jury unless evidence is admitted supporting the defense.

If the issue of the existence of a defense is submitted to the jury, the court shall charge that a reasonable doubt on the issue requires that the defendant be acquitted.

A ground of defense in a penal law that is not plainly labeled in accordance with this chapter has the procedural and evidentiary consequences of a defense.
