The appellant was acquitted at trial of refusing to provide a suitable breath sample.
The Crown appealed to the summary conviction appeal court, which quashed the acquittal and entered a conviction.
The appellant appealed to the Court of Appeal.
The Court of Appeal agreed that the trial judge erred in law by considering the officer's knowledge of the alert device's workings as relevant to whether the appellant intentionally refused to provide a sample.
However, the Court held that the summary conviction appeal court judge erred by entering a conviction, as the trial judge had not made all the necessary findings of fact.
The appeal was allowed, the conviction was set aside, and a new trial was ordered.
