Criminal law 2023 ONCA 300

R. v. Bruzzese

The appeal is allowed and a new trial ordered because the trial judge misdirected the jury by excluding the defence inference that absence of forensic evidence could raise a reasonable doubt and failed to correct the Crown's unsupported scientific submissions about the toxicology report; those material errors undermined the defence and created trial unfairness such that the curative proviso does not apply.

  • Attempted murder
  • Jury instructions
  • Forensic dna evidence
  • Toxicology evidence
  • Crown closing submissions
  • New trial

Criminal law 2022 ONCA 445

R. v. J.A.

The common-sense inference instruction was proper because the evidence, including toxicology showing toxic diphenhydramine levels and alcohol in a young child and the deliberate isolation of the children while administering adult medication and alcohol, made death or serious bodily harm a reasonably predictable consequence; the trial judge's instruction was therefore appropriate and any minor failures to directly link evidence to legal elements were not reversible error. All other grounds of appeal were rejected and convictions upheld.

  • Murder
  • Attempted murder
  • Mens rea
  • Jury instructions
  • Common-sense inference
  • Toxicology evidence

  • Due diligence

Criminal law 2018 ONCA 949

R. v. Dixon

The appeal is dismissed because the trial judge's credibility findings were supported by the evidence including eyewitness testimony and a toxicology report; she reasonably concluded the complainant lacked capacity to consent and there was no misapprehension of the evidence on toxicology or DNA, nor any indication the criminal record was used for an improper propensity purpose.

  • Consent capacity
  • Toxicology evidence
  • Dna evidence
  • Use of prior convictions
  • Credibility findings
  • Appeal standards

Criminal law 2015 ONCA 782

R. v. Brown

The trial judge's instructions on intoxication and on planning and deliberation contained the essential legal elements and the absence of an explicit comparison of degrees of intoxication did not vitiate the charge; the judge's comments on the defence toxicologist were supported by the evidence and did not unfairly undermine the defence; therefore the appeal is dismissed.

  • Murder
  • Intoxication
  • Jury instructions
  • Planning and deliberation
  • Toxicology evidence
  • Appeal

  • Circumstantial evidence
  • Witness credibility
  • Vetrovec warnings
  • Collusion

Criminal law 2008 ONCA 340

R. v. Reeve

The Court held the toxicology fresh evidence was admissible on appeal because it was reliable, relevant to decisive issues (timing of last drink, credibility, planning and drowning), and sufficiently cogent that it could reasonably be expected to have affected the jury’s verdict; the failure to challenge the Crown toxicologist at trial was not a bar to admission because the new evidence corrects an unanticipated and significant factual error in the trial evidence; accordingly the conviction was quashed and a new trial on the first degree murder charge ordered.

  • Fresh evidence on appeal
  • Admissibility
  • Toxicology evidence
  • Pathology evidence
  • Murder - first degree
  • Planning and deliberation
