The judgment of the Court was delivered orally by
 LeBel J. — The Crown has conceded and we agree with the Alberta Court of Appeal that the trial judge made an error in allocating the burden of proof. But we agree with Fraser C.J., in dissent, that this error may have tainted the evaluation of the evidence as to whether excessive force had been used by a police officer. In the circumstances of this case, the proviso of s. 686(1)(b)(iii) of the Criminal Code, R.S.C. 1985, c. C-46, could not apply. For these reasons, the appeal is allowed and the appellant’s conviction is quashed. As the parties have requested in such an event, a new trial is ordered on the same charges.
Solicitors for the appellant: Royal Teskey, Edmonton.
