The Coalition Inclusion Québec — a group that includes Roman Catholics, Jews, Sikhs and Muslims — is challenging the law in court, along with three teachers, including two Muslims and a Roman Catholic.

Perri Ravon, a lawyer who has worked on two of the lawsuits against the ban, said that at least for now, “the law is disproportionately affecting Muslim women because the hijab is an outwardly visible religious symbol.” She noted that a Catholic cross was less conspicuous since it could be concealed in a blouse or a shirt while at work.

Nonetheless, the Catholic teacher named in one of the suits, Andréa Lauzon, who wears a visible cross and medallion of the Virgin Mary, said in court papers that her faith and identity were inextricably bound, and that her constitutional right to freedom of religion was being breached.

The ban has its roots in Quebec’s historic evolution into an abidingly secular society with a visceral distrust of religion, stemming from the so-called Quiet Revolution in the 1960s, when Quebecers revolted against dominance of the Roman Catholic Church.

Jean Duhaime, emeritus professor of religion at the University of Montreal, said that even before the recent law, the wearing of crosses in the public sector was stigmatized and discouraged in Quebec society.

He said Catholic opponents to the ban were in solidarity with other religious groups, adding that many proponents of the law saw Muslims wearing head scarves as “the phantom of religion reappearing in Quebec while viewing the hijab as an instrument of patriarchal domination.”
