The Defendant charged with the rape of his stepson's girlfriend (C ), had been approached by C because of his interest in hypnosis. C wondered whether hypnosis could increase sexual pleasure. Following a party, C was apparently hypnotized and penetration occurred. Issues in the trial presented to the Court by the expert‐witness included: the motivation of C, the influence of alcohol on hypnotic responsivity, awareness during hypnosis, coercion, controllability and simulation. Convinced that C was not hypnotized, the jury's verdict was Guilty of Unlawful Intercourse. Mitigation resulted in a sentence of nine months, suspended for two years.
