The accused was charged with sexually assaulting a young child.
At trial, the defence cross-examined the complainant on her two-and-a-half-year delay in reporting the abuse, suggesting fabrication.
The Crown called a child psychologist to testify that delayed disclosure is common and does not indicate falsehood.
The trial judge admitted the expert evidence, and the accused was convicted.
The Court of Appeal ordered a new trial, holding the expert evidence was inadmissible.
The Crown appealed to the Supreme Court of Canada solely on the admissibility of the expert evidence.
The Supreme Court dismissed the appeal, holding that the expert evidence was not necessary because the principle that delay does not equate to falsehood is not outside the normal experience of a jury and could be addressed through a proper jury instruction.
