The appellant was convicted of breaking, entering, and possession of stolen property.
At trial, a defence witness testified that he, not the appellant, committed the crime.
The Crown cross-examined the witness on his knowledge of the protection against self-incrimination under s. 13 of the Charter.
The trial judge disbelieved the witness and convicted the appellant.
The Court of Appeal upheld the conviction.
The Supreme Court of Canada held that cross-examining a witness on their knowledge of s. 13 should rarely be permitted, as its prejudicial effect generally outweighs its probative value.
However, the Court applied the curative proviso, finding that the trial judge's reliance on the impugned testimony was minimal and no substantial wrong or miscarriage of justice occurred.
The appeal was dismissed.
