HIV-positive person who did not disclose status convicted of attempted aggravated assault

On 18 September 2003, the Supreme Court of Canada released its unanimous decision in Williams. This is the first case on the issue of criminal liability for HIV exposure decided by the court since its 1998 decision in the Cuerrier case. Williams raised the issue of whether persons with HIV who have unprotected sexual intercourse without disclosing their status to a sexual partner who might already have been infected with the virus, can be convicted of aggravated assault or attempted aggravated assault. The Supreme Court decided that only a charge of attempted aggravated assault could stand. The decision is also significant because the Supreme Court's comments on two ancillary issues may lead to a significant extension of the criminal law related to HIV transmission or exposure.
