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: • 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, it is justifiable under section 1 of the
Charter; • whether the meaning of the term "wrong" in section 16(2) of the
Code should be restricted to "legally wrong"; • whether section 16(3) of the
Code provides an alternative defence if the conditions of section 16(2) were not met; and • 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. 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==
