Whether Massachusetts rape law requires the Commonwealth to disprove a defendant's honest and reasonable belief that the complainant consented.
Holding
No. Under G. L. c. 265, § 22, lack of consent is an element of rape, but the Commonwealth need not prove that the defendant knew of the lack of consent or intended to engage in nonconsensual intercourse.
Reasoning
The rape statute requires proof that the defendant had sexual intercourse and compelled the complainant to submit by force or threat of bodily injury and against the complainant's will. Massachusetts treats force or threat, and actual lack of consent at the time of penetration, as separate components of the second element.
A mistake-of-fact theory applies only when a mistake negates a mental state that the offense requires for a material element. Massachusetts rape law is a general-intent offense: the required intent is the intent to engage in intercourse by force, not an intent or knowledge that the intercourse is without consent.
The court's precedents, particularly Commonwealth v. Grant and Commonwealth v. Ascolillo, establish that the defendant's perception of consent is not a material element in a rape prosecution. Thus, an honest or reasonable belief in consent cannot negate a mens rea that the statute does not require.
This conclusion does not make rape a strict-liability offense. The Commonwealth must still prove that the defendant intentionally engaged in intercourse by force or threat and that the complainant in fact did not consent.
Massachusetts's force requirement also reduces the concern that a person will be convicted based solely on an innocent misunderstanding. Except where a complainant is incapable of consent, the prosecution must establish physical force, constructive force, or a threat of force in addition to actual nonconsent.
The court declined to follow jurisdictions that recognize a reasonable-mistake-of-consent theory through statutory culpability requirements or different judicial constructions of their rape statutes. Recognizing the proposed defense could also undermine Massachusetts's settled rule that a rape complainant need not physically resist in order to establish nonconsent.
