Mahe v Alberta, [1990] 1 S.C.R. 342 is a leading decision of the Supreme Court of Canada. The ruling is notable because the court established that section 23 of the Canadian Charter of Rights and Freedoms requires parents of the official-language minority in each province to have the right either to be represented on the school board or to have a school board of their own to provide adequate protection for the education rights of their children.
