SUPREME COURT OF CANADA - R. v. ALEX

This case is an excellent review of the history of impaired driving legislation.  It concludes that evidentiary procedures that date back to 1969 do not have to include the requirement that the Crown establish that the demand for the breath sample made by the police was a “lawful” demand before the Crown can take advantage of the evidentiary procedures. R. v. Alex, 2017 SCC 37
