Questions and positions
Legal issues
- 01
Whether the trial judge erred in denying defence disclosure of records relating to three criminal investigations and a Centre jeunesse report
- 02
Whether the trial judge misinterpreted and improperly treated crucial evidence causing a miscarriage of justice
- 03
Whether expert testimony of Mr. Poulin was admissible and within proper scope
- 04
Whether a new trial is required and whether the retrial may proceed before the same judge
Party arguments
- Applicant
- The Crown argued the trial judge correctly denied disclosure because the documents did not meet the O'Connor/McNeil threshold of likely relevance and that the expert exceeded proper scope so his evidence was irrelevant and unnecessary per Sekhon; the guilty verdict should be restored.
- Respondent
- The defence argued the records were likely relevant and necessary to make full answer and defence, that the trial judge mischaracterized and dismissed material evidence and improperly excluded or discounted expert opinion central to the defences, and that these errors required setting aside the conviction and ordering a new trial.
05
Court’s reasoning
Legal principles
- 01
R. v. O'Connor; R. v. McNeil
Disclosure of third-party records requires a threshold showing of likely relevance to the accused's full answer and defence
- 02
R. v. Sekhon
Admissibility of expert evidence requires relevance and necessity and experts must stay within their proper scope
- 03
Supreme Court majority in R. v. Deslauriers, 2021 SCC 3
A new trial is warranted where legal errors by the trial judge create a reasonable possibility that the accused's right to make full answer and defence was impaired
- 04
Common law/Charter principles as applied in jurisprudence cited in judgment
Accused's right to make full answer and defence is a fundamental fairness guarantee in criminal process
06
Ratio, limits and disposition
Ratio decidendi
The majority dismissed the Crown appeal and upheld the Court of Appeal's setting aside of the conviction and ordering of a new trial because the trial judge erred in denying disclosure of third-party records and in her treatment of key evidence and expert testimony, creating a reasonable possibility that the defence was impaired and a miscarriage of justice occurred.
Obiter and limits
- Dissenting judges would have found the defence documents did not meet the likely relevance threshold and that the expert went beyond proper scope and was neither relevant nor necessary.
- Although recusal issues were not necessary to decide, the Court indicated that if the Crown elects to retry, the retrial must proceed before a different trial judge.
Court disposition
Appeal dismissed; the Quebec Court of Appeal's order setting aside the conviction and ordering a new trial is upheld.
- Appeal dismissed.
- Conviction set aside and new trial ordered on both counts.
- If the Crown elects to retry the accused, the retrial must proceed before a different trial judge.

272. APPEAL from a judgment of the Quebec Court of Appeal (Duval Hesler C.J. and Chamberland and Schrager JJ.A.), 2020 QCCA 484, 453 D.L.R. (4th) 234, 63 C.R. (7th) 179, [2020] Q.J. No. 2073 (QL), 2020 CarswellQue 12673 (WL Can.), setting aside the conviction for manslaughter entered by Roy J., 2017 QCCQ 11018, [2017] J.Q. no 13259 (QL), 2017 CarswellQue 8663 (WL Can.), and ordering a new trial. Appeal dismissed, Abella and Brown JJ. dissenting. Julie Laborde and Marie‑Claude Bourassa, for the appellant. Tristan Desjardins and Nadine Touma, for the respondent. English version of the judgment of the Court delivered orally by [1] The Chief Justice — The Crown appeals as of right on questions of law further to the majority judgment of the Quebec Court of Appeal setting aside the guilty verdict entered by Judge Joëlle Roy of the Court of Québec and ordering a new trial. A majority of this Court would dismiss the appeal for the reasons given by Chamberland J.A. [2] Judge Roy erred in law in denying Mr. Deslauriers the right to obtain and, if need be, file documents relating to the existence of three criminal investigations and a report from the Centre jeunesse des Laurentides involving the victim. There was a likely and reasonable possibility that the information in question could assist Mr. Deslauriers in exercising his right to make full answer and defence. [3] Moreover, Judge Roy
erred in her interpretation and treatment of the evidence crucial to the accused, such as to cause a miscarriage of justice. Because of our reasons, however, it is not necessary to dispose of this question already decided by the Quebec Court of Appeal. Judge Roy also erred in her treatment of the testimony given by an expert, Mr. Poulin, concerning Mr. Deslauriers’s conduct as a police officer, which was central to his defences. [4] Finally, although it is not necessary to deal with the recusation aspect of the judgment under appeal, and insofar as the Crown wishes to continue the proceedings leading to a second trial, it will have to proceed before another trial judge. For these reasons, the appeal is dismissed. [5] Abella and Brown JJ. are of the view that the documents sought by the defence do not meet the threshold of “likely relevance” within the meaning of R. v. O’Connor, [1995] 4 S.C.R. 411, and R. v. McNeil, 2009 SCC 3, [2009] 1 S.C.R.
66. They are also of the view that the expert, Bruno Poulin, strayed beyond the proper scope of his expert evidence and that his testimony was neither relevant nor necessary within the meaning of R. v. Sekhon, 2014 SCC 15, [2014] 1 S.C.R.
272. For these reasons, they would have allowed the appeal, set aside the Court of Appeal’s judgment and restored the guilty verdict. Judgment accordingly. Solicitor for the appellant: Director of Criminal and Penal Prosecutions, Longueuil. Solicitors for the respondent: Desjardins Côté, Montréal; Poupart, Touma, Montréal.
