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.

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.
