The Supreme Court of Canada is the highest court in the country. It is made up of nine judges appointed by the Canadian government. At least three judges must be chosen from among the judges of the Québec Court of Appeal or the Québec Superior Court, or must have been members of the Barreau du Québec for at least ten years at the time of their appointment. The Supreme Court sits in Ottawa.
The Supreme Court has final jurisdiction in criminal, civil and constitutional matters. The Supreme Court may interpret the Canadian constitution, determine the constitutionality of a law and interpret federal or provincial laws. It is also responsible for examining questions relating to the powers of Parliament and the provincial governments when such questions are referred to it by the Governor General in Council. In short, the Supreme Court hears matters of national interest. No lower court can render a judgment that goes against a Supreme Court decision.
The decisions of the Supreme Court are always final and without appeal. As a rule, since the Supreme Court decides which cases it will hear, appeals to it must be authorized.
