Section 76-2-304 - Ignorance or mistake of fact or law(1) Unless otherwise provided, ignorance or mistake of fact which disproves the culpable mental state is a defense to any prosecution for that crime.(2) Ignorance or mistake concerning the existence or meaning of a penal law is no defense to a crime unless: (a) Due to his ignorance or mistake, the actor reasonably believed his conduct did not constitute an offense, and(b) His ignorance or mistake resulted from the actor's reasonable reliance upon: (i) An official statement of the law contained in a written order or grant of permission by an administrative agency charged by law with responsibility for interpreting the law in question; or(ii) A written interpretation of the law contained in an opinion of a court of record or made by a public servant charged by law with responsibility for interpreting the law in question.(3) Although an actor's ignorance or mistake of fact or law may constitute a defense to the offense charged, he may nevertheless be convicted of a lesser included offense of which he would be guilty if the fact or law were as he believed.Amended by Chapter 32, 1974 General Session
