However, not all highest courts are named as such. Civil law states do not tend to have singular highest courts. Additionally, the highest court in some jurisdictions is not named the "Supreme Court", for example, the High Court of Australia; this is because decisions by the High Court could formerly be appealed to the Privy Council. On the other hand, in some places the court named the "Supreme Court" is not in fact the highest court; examples include the New York Supreme Court, the Supreme Courts of several Canadian provinces/territories and the former Supreme Court of Judicature of England and Wales, which are all superseded by higher Courts of Appeal.

What kinds of governed nations may not have a specific, individual high court?
