What is the standard of conduct of a trial judge in a sexual assault case?

Apart from exceptional cases where it would be needless to do so, a trial judge must also review the substantial parts of the evidence adduced at trial, and give the jury the position of the defence, so that the jury may appreciate the value and effect of the evidence and how they are to apply the law to their findings of fact. The jury must be left with an adequate understanding of the evidence as it relates to the relevant issues in the trial: Azoulay v. The Queen, 1952 CanLII 4 (SCC), [1952] 2 S.C.R. 495, at pp. 497-98; Cluett v. The Queen, 1985 CanLII 52 (SCC), [1985] 2 S.C.R. 216, at p. 231.
