Multani v. Commission scolaire Marguerite-Bourgeoys, 2006 SCC 6, [2006] 1 S.C.R. 256

Multani v. Commission scolaire Marguerite-Bourgeoys, the Supreme Court of Canada's own 2006 ruling, held that an absolute school prohibition on a Sikh student wearing a kirpan infringed freedom of religion and was not justified under the Charter's limitation clause. Its strength is that it is the Court's own opinion, the primary record of what it actually held. Its limit is that it rules on the specific school policy before it rather than offering a general account of kirpan practice across Sikh communities, which needs separate sources.
