Criminal law 2023 ONCA 446

R. v. Cummins

The Court upheld the trial judge's discretionary decision to permit the Crown to use the appellant's prior testimony because the evidence did not arise from Crown misconduct that would attract s.653.1 protection and the judge reasonably concluded the accused could be confronted with inconsistent testimony; however, the jury charge misstated the required causal link for the 'single transaction' test for s.231(5), creating a real possibility of prejudice, so the conviction for first-degree murder was set aside and substituted with second-degree murder and the matter remitted to determine parole…

R. v. McGregor

Continuing illegal domination is an organizing principle and not a separate element of s.231(5)(e); however, the trial judge's charge contained serious and prejudicial errors—contradictory and unclear directions on the permissible use of post-offence conduct (notably the 'I was jumped' disclaimer), misdirection on relevance to provocation, and a decision tree that conflated provocation with mens rea—which together undermined the integrity of the verdict and warranted allowing the appeal, setting aside the first degree murder conviction and the stay on the kidnapping count, and ordering a new…

Criminal law 2017 ONCA 297

R. v. Gayle

Both appeals dismissed: trial judge did not err in admitting and instructing on after-the-fact conduct or in admitting the bat; any weakness in linkage went to weight; repeated jury instructions prevented misuse of co-accused statements against Fedrick; modified W. (D.) instruction was adequate; severance was not required and no prejudice arose sufficient to overturn convictions.

  • First degree murder
  • Constructive murder
  • After-the-fact conduct
  • Consciousness of guilt
  • Admissibility of exhibits
