New Hampshire § 626-3 - Section 626:3 Effect of Ignorance or Mistake.

§ 626-3. Section 626:3 Effect of Ignorance or Mistake.

I. A person is not relieved of criminal liability because he acts under a mistaken belief of fact unless: (a) The mistake negatives the culpable mental state required for commission of the offense; or (b) The statute defining the offense expressly provides that such mistake is a defense; or (c) Such mistake supports a defense of justification as defined in RSA 627. II. A person is not relieved of criminal liability because he acts under a mistaken belief that his conduct does not, as a matter of law, constitute an offense unless his belief is founded upon a statement of the law contained in a statute or other enactment, or an administrative order or grant of permission, or a judicial decision of a state or federal court, or a written interpretation of the law relating to the offense officially made by a public servant, agency or body legally empowered with authority to administer, enforce or interpret such law. The defendant must prove a defense arising under this subsection by a preponderance of evidence.
