Puisne
Puisne is a legal term of art used mainly in British English meaning "inferior in rank".
Judicial usage
The judges and barons of the national common law courts at Westminster, other than those having a distinct title, were called puisne. This was reinforced by the Supreme Court of Judicature Act 1877 following which a "puisne judge" is officially any of those of the High Court other than the Lord Chancellor, the Lord Chief Justice of England and the Master of the Rolls.Puisne courts existed as lower courts in the early stages in the judiciary in British North America, in particular Upper Canada and Lower Canada. The justices of the Supreme Court of Canada other than the Chief Justice are still referred to as puisne justices.
