Puisne Judge

Puisne (from Old French puisne, modern puîné, later born, inferior; Lat. postea, afterwards, and natus, born) is a term in law meaning " inferior in rank." It is pronounced "puny," and the word, so spelled, has become an ordinary adjective meaning weak or undersized.The judges and barons of the common law courts at Westminster, other than those having a distinct title, were called puisne. By the Supreme Court of Judicature Act 1877, a "puisne judge" is deemed a judge of the High Court other than the Lord Chancellor, the Lord Chief Justice of England, the Master of the Rolls, the Lord Chief Justice of the Common Pleas, and the Lord Chief Baron of the Exchequer, and their successors respectively. See now the Supreme Court Act 1981, section 4.

A Puisne Justice or Puisne Judge (pronounced puny) is the title for a regular member of a Court. This is distinguished from the head of the Court who is known as the Chief Justice or Chief Judge. The term is used almost exclusively in common law jurisdictions such as England, Canada, Australia, and formerly in Hong Kong. Generally, the term is only used in relation to judges of a superior court, eg the Supreme Court or the High Court of a jurisdiction. The equivalent term in the United States is Associate Justice.
