Whether an honest and reasonable mistake of fact about a victim's age is a defense to a statutory-rape charge.
Holding
Yes. A defendant may defend against statutory rape by showing that he honestly and reasonably believed the victim was sixteen years old or older.
Reasoning
Alaska's prior decisions established that serious criminal liability ordinarily requires a consciousness of wrongdoing. In Speidel, Alex, and Kimoktoak, the court explained that imposing severe criminal punishment for innocent or inadvertent conduct, without a culpable mental state, violates due process.
Statutory rape was a serious felony, carrying up to twenty years' imprisonment for an offender under nineteen and potentially any term of years for an older offender. It therefore could not be treated as a narrow public-welfare offense, a category generally reserved for regulatory violations with comparatively minor penalties and little stigma.
Although the statutory-rape provision did not expressly state a mental-state requirement, legislative silence did not establish strict liability. Alaska courts ordinarily infer criminal intent into felony statutes unless the offense is properly classified as a public-welfare offense. Reading in that requirement also avoided construing the statute in a way that would create a constitutional due-process problem.
A reasonable mistake of fact is the means by which a defendant may show the absence of the criminal intent required for the offense. Thus, the jury could acquit if it had a reasonable doubt whether the defendant honestly and reasonably believed that T.D.G. was at least sixteen.
