The Crown appealed a summary conviction acquittal on charges of impaired driving and refusal to provide a breath sample.
The appeal court held that the trial judge applied the wrong legal standard when assessing whether the police officer had reasonable grounds to demand a roadside screening test, requiring proof of probable impairment rather than a reasonable suspicion that alcohol was present in the accused’s body.
The court also found legal errors in the trial judge’s failure to provide reasons for excluding evidence under s. 24(2) of the Charter and in dismissing the impaired driving charge without permitting Crown submissions.
Given that the trial judge had already made final determinations on key issues, the matter could not be meaningfully remitted to complete the trial.
The acquittal was set aside and a new trial ordered.
