Summary

Keywords

Criminal law — Reasonable verdict — Appeals — Whether a verdict is reasonable when a court of appeal is of the opinion that the case against the accused was far from overwhelming — Can a conviction be reasonable even though the circumstantial evidence gives rise to inferences that favour an acquittal more than a conviction — Whether the test for an unreasonable verdict should be expanded to allow a court of appeal to set aside what, on its face, is an unsafe verdict?

On March 2, 2011, Mr. Lanteigne was murdered. His husband, Mr. Papasotiriou, and a co-accused were charged with first degree murder. Mr. Papasotiriou was living in Greece at the time of the murder and the Crown’s case against him relied on circumstantial evidence. A jury convicted Mr. Papasotiriou of first degree murder. The Court of Appeal dismissed an appeal from the conviction.
