 Tupper's position on the Manitoba Schools Act was that French Catholics in Manitoba had been promised the right to separate state-funded French-language Catholic schools in the Manitoba Act of 1870.Thus, even though he personally opposed French-language Catholic schools in Manitoba, he believed that the government should stand by its promise and therefore oppose Dalton McCarthy's Manitoba Schools Act.He maintained this position even after the Manitoba Schools Act was upheld by the Judicial Committee of the Privy Council.
