PDF version: Blow over? Think twice before blaming it on the flu.
Decision considered: R v Kasim, 2011 ABCA 236.
The Respondent claimed to have drunk no more than 3 or 4 beers between 7 and 8:30 p.m. on September 18, 2008. He was behind the wheel soon after. At about 9 p.m. he complied with a lawful demand for an Intoxilyzer breath sample and the two samples he provided measured 100 mg percent, or 20 mg percent over the legal maximum of 80 mg of alcohol in 100 millilitres of blood. At trial the Respondent testified that his body temperature was elevated as he was suffering from the flu or a fever that day. This testimony was corroborated, and the trial judge accepted it. The Respondent’s expert witness, Dr. Malicky, testified that given the Respondent’s elimination rate, and an elevated body temperature, “his blood alcohol level at the time should have been approximately 36 mg percent if he had three containers of beer, and 60 mg percent if he had four containers of beer” (R v Kasim, [2010] AJ No 969, para 64). The Respondent argued that the test results were therefore askew and that raised a reasonable doubt as to whether he the violated the Criminal Code (RSC, 1985, c C-46). Both the Provincial Court judge and Queen’s Bench summary conviction appeal judge found for the Respondent. By consent order the Crown appealed to the Court of Appeal on a single issue: “The summary conviction appeal judge erred in law in her interpretation of s. 258(1) (c) of the Criminal Code” (CA decision at para 7). These Criminal Code provisions set out presumptions that subject to certain time and other limitations Intoxilyzer readings of blood alcohol are accurate. The provisions also limit permissible challenges to the presumed accuracy.
