The appellant, William Cummins, appealed his conviction for first-degree murder and unlawful confinement.
The appeal raised two main issues: the trial judge's mid-trial ruling allowing the Crown to use the appellant's prior testimony from a mistrial, and the application of constructive murder provisions under s. 231(5) of the Criminal Code.
The Court of Appeal upheld the trial judge's discretionary decision regarding the use of prior testimony, finding no error.
However, the court found that the trial judge erred in instructing the jury on the "same transaction" test for constructive murder by stating that the unlawful confinement did not need a causal connection to the murder, which contradicted established jurisprudence.
Consequently, the first-degree murder conviction was reduced to second-degree murder, and the matter was remitted for parole eligibility determination.
