The respondents sought to be registered as Indians under s. 6(1)(a) of the Indian Act, arguing that the 1952 Order-in-Council enfranchising their ancestor was obtained by fraud.
The Registrar refused the application, registering the ancestor under s. 6(1)(d) instead, which precluded the descendants from registration.
The Superior Court allowed the respondents' appeal, finding the Registrar could look behind the Order-in-Council.
The Court of Appeal allowed the Crown's appeal, holding that the Registrar and the Superior Court lack jurisdiction to invalidate or look behind a subsisting Order-in-Council, as exclusive jurisdiction to review such federal orders rests with the Federal Court.
