Intoxication as Defense

2C:2-8. Intoxication

as a possible defense to a criminal charge

a. Except as provided in subsection d. of this section, intoxication of the actor is not a defense unless it negatives an element of the offense.

b. When recklessness establishes an element of the offense, if the actor, due to self-induced intoxication, is unaware of a risk of which he would have been aware had he been sober, such unawareness is immaterial.

c. Intoxication does not, in itself, constitute mental disease within the meaning of chapter 4.

d. Intoxication which (1) is not self-induced or (2) is pathological is an affirmative defense if by reason of such intoxication the actor at the time of his conduct did not know the nature and quality of the act he was doing, or if he did know it, that he did not know what he was doing was wrong. Intoxication under this subsection must be proved by clear and convincing evidence.

e. Definitions. In this section unless a different meaning plainly is required:

(1) "Intoxication" means a disturbance of mental or physical capacities resulting from the introduction of substances into the body;

(2) "Self-induced intoxication" means intoxication caused by substances which the actor knowingly introduces into his body, the tendency of which to cause intoxication he knows or ought to know, unless he introduces them pursuant to medical advice or under such circumstances as would afford a defense to a charge of crime;

(3) "Pathological intoxication" means intoxication grossly excessive in degree, given the amount of the intoxicant, to which the actor does not know he is susceptible. ? a. Ignorance or mistake as to a matter of fact or law is a defense if the defendant reasonably arrived at the conclusion underlying the mistake and:

(1) It negatives the culpable mental state required to establish the offense; or

(2) The law provides that the state of mind established by such ignorance or mistake constitutes a defense.

b. Although ignorance or mistake would otherwise afford a defense to the offense charged, the defense is not available if the defendant would be guilty of another offense had the situation been as he supposed. In such case, however, the ignorance or mistake of the defendant shall reduce the grade and degree of the offense of which he may be convicted to those of the offense of which he would be guilty had the situation been as he supposed.

c. A belief that conduct does not legally constitute an offense is a defense to a prosecution for that offense based upon such conduct when:

(1) The statute defining the offense is not known to the actor and has not been published or otherwise reasonably made available prior to the conduct alleged; or

(2) The actor acts in reasonable reliance upon an official statement of the law, afterward determined to be invalid or erroneous, contained in (a) a statute, (b) judicial decision, opinion, judgment, or rule, (c) an administrative order or grant of permission, or (d) an official interpretation of the public officer or body charged by law with responsibility for the interpretation, administration or enforcement of the law defining the offense; or

(3) The actor otherwise diligently pursues all means available to ascertain the meaning and application of the offense to his conduct and honestly and in good faith concludes his conduct is not an offense in circumstances in which a law-abiding and prudent person would also so conclude.

The defendant must prove a defense arising under subsection c. of this section by clear and convincing evidence.
