The Crown appealed the respondent's acquittal on an over 80 charge.
The trial judge had acquitted the respondent after finding that the failure to conduct an annual inspection of the breathalyzer amounted to improper maintenance, raising a reasonable doubt about the reliability of the results.
On appeal, the Crown argued that a 2012 Alcohol Test Committee position paper constituted new evidence justifying revisiting the Supreme Court's decision in St. Onge Lamoureux.
The summary conviction appeal judge rejected this argument but found that the trial judge misapprehended the evidence by elevating a recommendation for yearly inspections into a rule without a direct link to a malfunction.
The appeal was allowed and a new trial ordered.
