Criminal law 2025 NSPC 25

R v EP

The accused was guilty of manslaughter because he planned and participated in a group assault that significantly contributed to the deceased's death; a reasonable person in his circumstances would have foreseen a risk of non‑trivial bodily harm from the group assault (and from the presence/use of knives once he knew or believed others had them); intervening acts by MP and CP did not break the causal chain; abandonment failed because he did not provide timely, unequivocal communication or take reasonable steps to neutralize his prior participation.

  • Manslaughter
  • Party liability
  • Aiding and abetting
  • Common purpose (s.21(2))
  • Unlawful act manslaughter
  • Causation and intervening acts

Criminal law 2025 ONCA 519

R. v. Smoke

The appeals are dismissed because the charge as a whole fairly instructed the jury on burden, reasonable doubt, distinctions between direct and circumstantial evidence, aiding and abetting and the limited use of after-the-fact conduct; any single imprecise remark in the charge was harmless, and the jury’s verdicts were reasonable and supported by cumulative circumstantial evidence linking Eric to the shooting and by inferences about Andrew’s conduct and statements.

  • Aiding and abetting
  • After-the-fact conduct
  • Jury instructions
  • Circumstantial evidence
  • Reasonable doubt
  • Identification

Criminal law 2024 ONCA 387

R. v. Akindejoye

The trial judge did not err: his general and case-specific warnings adequately addressed any risk of collusion; admitting the in-dock identification was a lawful exercise of discretion because its probative value was admissible and the judge instructed the jury to give it no weight; and the Crown's improper remarks were remedied by clear corrective instructions, so a mistrial was not required. Appellate intervention was therefore unwarranted.

  • Identification evidence
  • Collusion
  • In-dock identification
  • Mistrial
  • Jury instructions
  • Publication ban
