Landmark Bill 21 Challenge Heard at Supreme Court

The Supreme Court of Canada has begun hearing a landmark constitutional challenge to Quebec’s secularism law, known as Bill 21, with the controversial notwithstanding clause taking centre stage in the proceedings that began this week.

Legal experts say the case could bring Canada into uncharted constitutional territory as the court examines whether there are limits to how provinces can use the notwithstanding clause to shield legislation from Charter challenges. The Quebec government has already renewed Bill 21 once in May 2024 for another five years.

“The Supreme Court of Canada will have to decide whether there are limits to how the notwithstanding clause can be used,” noted one intervenor in the case. The English Montreal School Board is among those arguing the law unconstitutionally affects official language minorities and women.

The hearing comes as Quebec prepares for an election this October, adding political significance to the court’s eventual ruling.

Feds Appeal Emergencies Act Ruling

The federal government is appealing to the Supreme Court a ruling that found its use of the Emergencies Act during the 2022 Freedom Convoy protests breached Charter rights. A January ruling from the Federal Court of Appeal upheld the earlier decision, prompting Ottawa’s appeal to the nation’s highest court.

Meanwhile, a group involved in the case has asked Chief Justice Richard Wagner to consider recusing himself from the upcoming Supreme Court hearing.

Court Reserves Decision on Facebook Privacy Case

The Supreme Court has delayed its ruling on a landmark privacy case involving Facebook’s role in the 2010s Cambridge Analytica scandal. The case examines whether Canadian courts have jurisdiction over the social media giant for data harvesting that affected millions of users worldwide.

The court’s decision, when it comes, could set important precedents for digital privacy and transnational data flows.

About the Supreme Court of Canada

The Supreme Court of Canada comprises nine justices appointed by the Governor in Council. All judges must have been either a judge of a superior court or a member of at least 10 years’ standing at the bar of a province or territory.

The court grants permission to between 40 and 75 litigants each year to appeal decisions from lower courts, serving as the ultimate arbiter of Canadian law. Originally composed of six justices when created in 1875, the court was expanded to seven and later to its current complement of nine.

A 1969 biographical study found that 88 percent of justices in the court’s history had held some form of prior public office before their appointment.
