R v Chaulk
R v Chaulk,  3 SCR 1303 is a leading decision of the Supreme Court of Canada on the interpretation and constitutionality of section 16(4) of the "Criminal Code", which provides for a mental disorder defence. Two accused individuals challenged the section as a violation of their right to the presumption of innocence under section 11(d) of the "Charter of Rights and Freedoms" (""Charter""). The Court upheld the section and provided a basis on which to interpret the section. Background. On September 3, 1985, 15-year-old Robert Chaulk and 16-year-old Francis Morrissette burglarized a  home in Winnipeg, and then stabbed and bludgeoned its sole occupant to death. One week later, they turned themselves in, making full confessions. The only defence raised was insanity within the meaning of section 16 of the "Criminal Code". Expert evidence was given at trial that Chaulk and Morrissette suffered from a paranoid psychosis which made them believe they had the power to rule the world and that the killing was a necessary means to that end. They believed they were above the ordinary law and thought they had a right to kill the victim because he was "a loser . They were both convicted of murder by a jury in the Manitoba Court of Queen's Bench, which was upheld on appeal. The major questions to the Supreme Court were: They were convicted of murder, but have appealed the decision on the basis of an error in instruction on the definition of the word appreciate" and "wrong". Opinion of the Court. There were three opinions: The accused were convicted of first degree murder. The only defence raised at trial was insanity, but this defence was rejected by the jury. The Court of Appeal upheld the conviction. This appeal is to  determine (1) whether section 16(4) of the "Criminal Code", which provides that, "Every one shall, until the contrary is proved, be presumed to be and to have been sane", infringes the presumption of innocence guaranteed in section 11(d) of the "Charter"; and, if so, whether section 16(4) is justifiable under section 1 of the "Charter"; (2) whether the meaning of the word "wrong" in section 16(2) of the "Code" should be restricted to "legally wrong"; (3) whether section 16(3) of the "Code" provides an alternative defence if the conditions of section 16(2) were not met; and (4) whether the trial  judge erred in permitting the Crown to split its case by presenting its evidence with respect to the sanity of the accused in rebuttal. Reasoning. Lamer CJC explained that there is a presumption of criminal capacity. For a minor child, the reverse is true. For a child over age 14, the presumption of incapacity is rebuttable. A claim of insanity undermines the "voluntariness" of either the actus reus or the "mens rea". It can also provide an excuse to criminal conduct, where intention is present. The defence can be raised in a number of ways, therefore. For example, the defence  can plead insanity to show a lack of capacity to understand right and wrong, or to show a cognitive breakdown leading to an irresistible impulse to act. The focus is on incapacity to form a mental element – a mentally disordered person does not have the capacity to distinguish between right and wrong. "Wrong" means more than legally wrong or knowing the law of the land; it means morally wrong as well. This decision overruled "Schwartz v R". The test requires that the defence establish that due to the mental illness, the accused could not appreciate that his conduct: "conformed to  normal and reasonable standards of society" "breaches a standard of moral conduct" "would be condemned." Lamer addresses the floodgates question. First, the presence of a mental disorder is required before this analysis is even undertaken. Second, moral standards are not judged on the personal standards of the accused. The mental disorder must inhibit the accused from appreciating society's standards of morality. The accused cannot substitute its own moral code and say that he was acting according to that code. Rationale. A trial judge must instruct the trier of fact that "appreciate that the act was wrong" means that  because of the mental disorder, the accused could not understand or comprehend society's moral condemnation of the conduct. Dissent. There were two dissenting opinions: Aftermath. Robert Chaulk was subsequently found not guilty by reason of insanity in a new trial. After four months of treatment, Robert Chaulk was found sane and released. In 1999, Robert Chaulk was accused of stabbing two of his neighbours to death on New Year's Day.
