The province's high court agreed with a Superior Court ruling that declared inoperative an article of the province's Highway Safety Code that allows police to randomly stop drivers without a reasonable suspicion that an offence has been committed.

The Court of Appeal says in the unanimous decision released today that the law violates Charter rights, including freedom from arbitrary detention and equality rights.

The legal action was brought by Joseph-Christopher Luamba, a 22-year-old Black Montrealer who said he had been stopped by Quebec police nearly a dozen times without reason, and none of the stops resulted in a ticket.

Superior Court Justice Michel Yergeau wrote in the October 2022 decision that "racial profiling does exist. It is not a laboratory-constructed abstraction .... It is a reality that weighs heavily on Black communities. It manifests itself in particular with Black drivers of motor vehicles."

Yergeau said evidence had shown over time that arbitrary power granted to the police to make roadside stops without cause became "for some of them, a vector, even a safe conduit for racial profiling against the Black community."

"The rule of law thus becomes ... a breach through which this sneaky form of racism rushes in," he added.

Luamba was backed by the Canadian Civil Liberties Association in his constitutional challenge of the practice.

The 2022 decision only affected random stops and not structured police operations such as roadside checkpoints aimed at stopping drunk drivers.

The decision was appealed by the provincial government, and some civil rights groups believe the matter could end up before the Supreme Court of Canada.

The Court of Appeal ruling by a three-judge panel gives the provincial government six months to make the necessary changes to the Highway Safety Code.
