Procedural Posture

Criminal Appeal / Appeal From Conviction and Sentence; Convictions Set Aside and New Trial Ordered

  1. 1 Whether Crown improperly used expert evidence to bolster complainant credibility

  3. 3 Whether Crown improperly cross-examined accused to elicit reasons why complainant would fabricate (false story cross-examination)

Ratio Decidendi

Convictions were set aside and a new trial ordered because the Crown improperly used expert evidence beyond its admitted scope to bolster credibility, the trial judge failed to intervene or give limiting instructions, and substantive errors in W.(D.) direction and improper cross-examination together created a material risk that the jury could not properly assess the complainant’s credibility, producing a miscarriage of justice.
