R v JA 2011 SCC 28 is a criminal law decision of the Supreme Court of Canada regarding consent in cases of sexual assaults. The court found that a person can only consent to sexual activity if they are conscious throughout that activity. If a person becomes unconscious during the sexual activity, then they legally cannot consent, whether or not they consented earlier. In addition to the two parties (J.A. and the Attorney General of Ontario), the Court heard from two interveners: the Attorney General of Canada and the Women's Legal Education and Action Fund (LEAF).
