Questions and positions
Legal issues
- 01
Whether the trial judge’s reasons were sufficient to permit meaningful appellate review
- 02
How to assess credibility and reliability of a witness with an intellectual or developmental disability
- 03
Whether expert evidence attributing general characteristics to a witness should be preferred over assessment of the individual’s demonstrated capacities
Party arguments
- Applicant
- The Crown argued the trial judge’s reasons were sufficient and that his acceptance of the complainant’s evidence implicitly justified rejection of the defence; the conviction should be restored.
- Respondent
- The respondent argued the Court of Appeal was correct: the trial judge failed to address the complainant’s reliability in light of expert evidence about her suggestibility and failed to give reasons for rejecting defence evidence, requiring a new trial.
05
Court’s reasoning
Legal principles
- 01
Supreme Court of Canada decision in R. v. Slatter (2020 SCC 36)
Appellate review requires reasons sufficient to permit meaningful review of findings on credibility and reliability.
- 02
Supreme Court of Canada decision in R. v. Slatter (2020 SCC 36) (para. 2)
When assessing testimonial reliability of individuals with intellectual or developmental disabilities, courts must focus on the individual’s demonstrated capacities to perceive, recall and recount events rather than on generalized expert attributes.
- 03
Supreme Court of Canada decision in R. v. Slatter (2020 SCC 36) (para. 2)
Over-reliance on expert evidence that attributes general characteristics can perpetuate harmful myths and impede truth‑seeking and access to justice.
06
Ratio, limits and disposition
Ratio decidendi
The appeal is allowed because the trial judge’s reasons were sufficient to permit meaningful appellate review and the proper approach to assessing testimony of a person with intellectual or developmental disability is to evaluate the individual’s actual capacities rather than rely on generalized expert characteristics; therefore the conviction is restored.

Accused convicted at trial of sexually assaulting complainant with intellectual and developmental disability — Majority of Court of Appeal holding that trial judge’s reasons were insufficient because he failed to address reliability of complainant’s evidence in view of expert evidence as to her suggestibility and failed to provide reasons for rejecting defence evidence — Majority of Court of Appeal setting aside conviction and ordering new trial — Dissenting judge holding that trial judge’s reasons allowed for meaningful appellate review on basis that they adequately addressed complainant’s reliability and that his rejection of defence evidence was implicit in his reasoned acceptance of complainant’s evidence — Conviction restored. APPEAL from a judgment of the Ontario Court of Appeal (Doherty, Pepall and Trotter JJ.A.), 2019 ONCA 807, 148 O.R. (3d) 81, 452 D.L.R. (4th) 4, 58 C.R. (7th) 18, 382 C.C.C. (3d) 245, [2019] O.J. No. 5073 (QL), 2019 CarswellOnt 16055 (WL Can.), setting aside the conviction of the accused for sexual assault and ordering a new trial. Appeal allowed.

Inc., DisAbled Women’s Network Canada and ARCH Disability Law Centre. Deepa Mattoo, for the intervener Barbra Schlifer Commemorative Clinic. Matthew R. Gourlay, for the intervener Criminal Lawyers’ Association of Ontario. The judgment of the Court was delivered orally by [1] Moldaver J. — We are all of the view that the appeal must be allowed, for the reasons of Justice Pepall, with which we agree. [2] We would simply underline that when assessing the credibility and reliability of testimony given by an individual who has an intellectual or developmental disability, courts should be wary of preferring expert evidence that attributes general characteristics to that individual, rather than focusing on the individual’s veracity and their actual capacities as demonstrated by their ability to perceive, recall and recount the events in issue, in light of the totality of the evidence. Over-reliance on generalities can perpetuate harmful myths and stereotypes about individuals with disabilities, which is inimical to the truth-seeking process, and creates additional barriers for those seeking access to justice. [3] Accordingly, we would allow the appeal and restore the conviction. Judgment accordingly. Solicitor for the appellant: Attorney General of Ontario, Toronto. Solicitors for the respondent: Reynolds O’Brien, Belleville; Pretsell, Davies, Thompson, Benton, Belleville. Solicitor
