R v. Alex. is a 2017 Supreme Court of Canada decision in which the Supreme Court had to determine whether the Crown needed to prove that a police officer’s request that an individual blow into an approved screening device was reasonable before it could admit the results of the breathalyzer without having to call a toxicologist and a technician as a witness.

1:20 – An overview of the facts of the case in R v. Alex. A person is pulled over during a seatbelt check in Penticton, British Columbia.  A police officer notices that he smelled an odour of liquor as he approached the vehicle and there was an open beer can on the floor near the passenger side. The driver, Mr. Alex, had “red cheeks” and “watery eyes.” There was nothing else to suggest that the person was impaired.  The driver had no difficulty parking the car and no difficulty exiting the vehicle. The police officer did not take any notes about why he thought Mr. Alex was drunk, but says that he wouldn’t have pulled him over if he did not think he had a reasonable suspicion.  The police officer requires that Mr. Alex use an approved screening device which he fails, which is almost double the legal limit of 0.08. He then takes him to a police station where his breath samples registered .140 and .130 mg of alcohol, which is almost double the legal limit.

8:35 – The result of a breathalyzer can be provided in court by means of a certificate rather than the prosecution needing to call a breath technician to attest to the accuracy of the readings and an expert toxicologist if (1) each sample was taken as soon as practicable after the time when the offence was alleged to have been committed and, in the case of the first sample, not later than two hours after that time, with an interval of at least fifteen minutes between the times when the samples were taken, (2) each sample was received from the accused directly into an approved container or into an approved instrument operated by a qualified technician, and (3) an analysis of each sample was made by means of an approved instrument operated by a qualified technician.
