with the majority's final decision were released by Gonthier and Wilson JJ. The sole dissenting judge was L'Heureux-Dubé J. Crown adducing evidence of insanity At the time of the case, Canadian common law allowed the Crown to adduce evidence of an accused person's insanity at the time of the alleged offence during the Crown's case over the objections of the accused. The majority found that a principle of fundamental justice required an accusatorial and adversarial criminal justice system, founded on respect for the autonomy and dignity of human beings. Therefore, the same principle required that an accused person has the right to control his or her own defence (assuming the person is found fit to stand for trial). The majority found that since the defence of insanity is an exemption to criminal liability, based on not being capable to form the criminal intent, it is a defence to the criminal charge, and therefore should not be interfered with by the Crown. The majority went on to find that if the Crown independently raised the defence of insanity, it could be inconsistent with the defence an accused person intends to rely on, putting the accused in a position of having to argue inconsistent defences. For example, the defence of insanity could be inconsistent with the defence of alibi. It could also undermine the accused's credibility with the jury, due to the stigma associated with the mentally ill. The majority also concluded that the accused's right to control their own defence is not an absolute right. For example, if an accused person puts their mental health at issue without going so far as to claim the defence of insanity, the Crown is entitled to "complete the picture". The majority agreed with the Crown that the principles of fundamental justice also required that a person who was insane at the time of an offence not be convicted of that offence. However, the majority found that still did not excuse breaching another principle of fundamental justice. Since the common law rule caused an accused person to lose their liberty, and since it violated a principle of fundamental justice, the majority found that the common law rule infringed section seven of the Canadian Charter of Rights and Freedoms. The majority did not need to decide whether it also violated other sections of the Charter. The majority went on to find that the common law rule
