In the Northern Territory a person is guilty of a crime if he/she has sexual intercourse with another person without the other person’s consent and knows about, or is reckless as to, the lack of consent. Consent is defined as “free and voluntary agreement.” Circumstances in which a person does not consent to sexual intercourse include circumstances where: force is used; the victim fears force or harm to themselves or someone else; the victim is unconscious or not capable of free agreement; or the victim is unable to understand the sexual nature of the act. In addition, consent is no longer assumed where the victim is married to the accused. The prosecution must prove beyond reasonable doubt that the accused knew that the victim was not consenting or was reckless as to whether the victim was consenting. Recklessness includes not giving any thought to whether the person is consenting to sexual penetration. A defendant is not guilty of the offence if he or she mistakenly believed that consent had been given.
