The accused was charged with operating a motor vehicle with a blood alcohol concentration over the legal limit.
The Crown relied on breath samples analyzed by an Intoxilyzer 8000C.
The central issue was whether the Crown could rely on the statutory presumption of accuracy under the newly enacted section 320.31(1) of the Criminal Code.
The court interpreted the new provision, concluding that the Crown must prove the actual concentration of the alcohol standard used in the calibration check and that it was certified by an analyst.
Because the Crown failed to tender the Certificate of Analyst or prove the concentration of the standard solution, the presumption of accuracy did not apply.
Without the presumption, the Crown could not prove the accused's blood alcohol concentration beyond a reasonable doubt, resulting in an acquittal.
