Louisiana Revised Statutes Tit. 14, § 42.1. Second degree rape

(1) When the victim is prevented from resisting the act by force or threats of physical violence under circumstances where the victim reasonably believes that such resistance would not prevent the rape.

(2) When the victim is incapable of resisting or of understanding the nature of the act by reason of stupor or abnormal condition of the mind produced by a narcotic or anesthetic agent or other controlled dangerous substance administered by the offender and without the knowledge of the victim.

(3) When the offender acts without the consent of the victim, the victim is thirteen years of age or older but less than seventeen years of age, and the difference between the age of the victim and the age of the offender is three years or greater. Lack of knowledge of the victim's age shall not be a defense.
