The Famous Five or The Valiant Five (French: Célèbres cinq) were five Alberta women who asked the Supreme Court of Canada to answer the question, "Does the word 'Persons' in Section 24 of the British North America Act, 1867, include female persons?" in the case Edwards v. Canada (Attorney General). The five women, Emily Murphy, Irene Marryat Parlby, Nellie Mooney McClung, Louise Crummy McKinney and Henrietta Muir Edwards, created a petition to ask this question. They sought to have women legally considered persons so that women could be appointed to the Senate. The petition was filed on August 27, 1927, and on 24 April 1928, Canada's Supreme Court summarized its unanimous decision that women are not such "persons".
The last line of the judgement reads, "Understood to mean 'Are women eligible for appointment to the Senate of Canada,' the question is answered in the negative." This judgement was overturned by the British Judicial Committee of the Privy Council on 18 October 1929. This case came to be known as the "Persons Case". Although Canadian women (white British/Canadian citizens) had the vote in many provinces and in federal elections by 1929, the case was part of a continent-wide drive for political equality, coming seven years after women's suffrage in the United States through the Nineteenth Amendment to the United States Constitution, and thus had important ramifications not just for women's rights but also because in ruling in favour of the appellants, the Privy Council engendered a radical change in the Canadian judicial approach to the Canadian constitution, an approach that has come to be known as the "living tree doctrine".
