Top court upholds breathalyzer procedures

OTTAWA • The Supreme Court of Canada is upholding procedures that permit shortcuts for allowing a motorist’s breathalyzer test results into evidence — even in cases where demanding the breath sample may have been unlawful.

In a 5-4 ruling Thursday dismissing the appeal of a British Columbia driver, the court affirmed the existing charter process for challenging a police officer’s decision to order a breath sample.

It means technicians and toxicologists can’t be forced to testify in court about the accuracy and relevance of breath tests when the argument is really about whether police had reasonable grounds to demand testing.

Instead, the Crown can rely on a simple certificate recording the breath readings of the accused. Ruling otherwise would require additional witnesses to attend court to give evidence on matters that have no connection to the lawfulness of the breath demand — and only add to the costs and delays in an already overburdened criminal justice system, Justice Michael Moldaver wrote on behalf of the majority.

“No one gains under this approach — but society as a whole loses out as precious court time and resources are squandered,” he said in the court’s reasons. “The evidentiary shortcuts were designed by Parliament to simplify and streamline drinking and driving proceedings.”

The Supreme Court upheld the impaired-driving conviction of Dion Henry Alex, who was stopped by police in Penticton, B.C., in April 2012. An RCMP officer detected the scent of liquor and saw an open can of beer on the floor beside a passenger in Alex’s van.

Alex failed a roadside test and was taken to the police detachment, where he blew above the legal blood alcohol limit in two subsequent tests.

At issue was the continuing relevance of a 1976 Supreme Court decision that said the Crown did not need to prove the demand for a breath test was lawful in order to rely on evidentiary shortcuts about the accuracy of test readings.

The introduction of the Charter of Rights and Freedoms in the 1980s added a new wrinkle, meaning that an accused person who argues a breath sample was obtained unlawfully could now initiate a charter challenge alleging unreasonable search and seizure.
