Quebec's law regulating the display of religious symbols by certain public sector employees is set to be reviewed by Canada's Supreme Court in a constitutional test case.

The legislation, known as Bill 21, prohibits public sector workers in positions of authority from wearing visible religious symbols while on duty. This includes teachers, police officers, judges, and other government employees.

The law has generated significant controversy since its implementation, with critics arguing it discriminates against religious minorities and violates constitutional protections for religious freedom. Supporters contend it upholds Quebec's secular values and maintains neutrality in public institutions.

Several legal challenges have been mounted against the legislation since it was enacted. The case reaching the Supreme Court represents the highest level of judicial review the law has faced.

The Supreme Court's decision will have significant implications for the balance between provincial authority to regulate public institutions and federal constitutional protections for religious rights. The case is expected to clarify the scope of religious freedom protections under Canada's Charter of Rights and Freedoms.
