I think that is an inappropriate interpretation. Some might call it absurd. I would even add that if we take the content of section 6 of the Supreme Court Act at face value, given that we're talking about Superior Court judges and Court of Appeal judges, that means that the chief justice of the Court of Quebec, the Honourable Élizabeth Corte, could not be appointed to the Supreme Court of Canada. I don't think that's an appropriate interpretation of section 6 of the Supreme Court Act.
