The accused was charged with operating a motor vehicle while blood alcohol content exceeded 80 mg per 100 ml of blood.
The Crown's case depended entirely on the results of an Approved Screening Device test and subsequent breath samples.
The accused brought a Charter application alleging breaches of sections 8, 9, and 10(b) of the Charter.
The court found that the officer lacked reasonable grounds to rely on the ASD results because he could not establish the device had been calibrated within the required timeframe, resulting in an unlawful arrest and arbitrary detention.
The court also found a breach of the right to counsel, as the officer failed to inform the accused of his right to search for counsel of choice, controlled all means of contacting counsel, and withheld information that the accused's father had called with a lawyer's name.
The evidence was excluded under section 24(2) of the Charter.
