Case Brief Summary & Legal Analysis

General Brief
3 min read

tl;dr: Defendant claimed a reasonable mistake of age defense to a charge of lewd conduct with a child under 14. The court rejected this, holding that the offense is a strict liability crime concerning the victim’s age due to the strong public policy of protecting young children.

Legal Significance: Establishes that lewd conduct with a child under 14 (Penal Code § 288) is a strict liability offense as to the victim’s age. A defendant’s reasonable mistake of age is not a defense, distinguishing it from statutory rape involving older minors.

Case Facts & Court Holding

Key Facts & Case Background

The defendant, Edward Olsen, was charged with lewd or lascivious conduct with Shawn M., who was 13 years and 10 months old. The factual accounts of the incident were disputed. Shawn testified that Olsen and a co-defendant forced their way into a trailer where she was sleeping and that Olsen had nonconsensual intercourse with her at knifepoint. The co-defendant testified that the encounter was consensual and initiated by Shawn. For the purposes of the legal issue on appeal, it was undisputed that Shawn had previously told Olsen she was over 16 years old and that she conceded her physical appearance was consistent with someone over that age. At trial, Olsen argued that his good faith, reasonable belief that Shawn was over the age of 14 constituted a defense to the charge under Penal Code § 288. The trial court rejected this mens rea argument and found him guilty.
