In a few places, the court named the "Supreme Court" is not in fact the highest court; examples include the Supreme Court of the State of New York and the former Supreme Court of Judicature of England and Wales. Conversely, the highest court in some jurisdictions is not named the "Supreme Court"; for example, the High Court of Australia.
