Yesterday the High Court handed down its decision in Stubley v Western Australia [2011] HCA 7, which concerns the admissibility of tendency evidence (or, as WA calls it, propensity evidence) or relationship evidence in a sexual offence proceeding. The case, in broad terms, is fairly straightforward. Several years after ceasing treatment, 2 women alleged that their psychiatrist, Stubley, had sexual intercourse with them during therapy sessions. They claimed that they either actively communicated their lack of consent, or that their acquiescence was not consent, but was improperly induced by threats and other misconduct. The prosecution sought to lead evidence from 3 other women who also alleged that Stubley had sexual intercourse with them in the context of a professional-client relationship. The defence case did not dispute the allegations of sexual intercourse, but relied on consent or belief in consent. The defence denied that consent was obtained by threats.
