The defendant was charged with driving with excess blood alcohol (over 80 mg per 100 mL of blood).
Officers conducted a RIDE spot check and the defendant failed a roadside screening test.
Two breath samples were provided at the station, registering 160 mg and 150 mg respectively.
The defence raised two Charter-based arguments and two substantive challenges: (1) that the presumption of identity in s. 258 of the Criminal Code does not survive its repeal (the Shaikh issue), and (2) that the Crown failed to establish the accuracy of the Intoxilyzer tests (the Flores-Vigil issue).
The court rejected both defence arguments, finding that the presumption of identity applies to pre-amendment offences and that the Crown established the preconditions for the presumption of accuracy through viva voce evidence.
The defendant was found guilty.
