A puisne judge, pronounced exactly like “puny,” is a regular member of a court who is not the chief justice or presiding judge. The title is administrative, not a comment on ability or authority: a puisne judge hears cases and issues rulings with the same legal force as the chief. The word appears most often in Commonwealth courts, including those in Canada, the United Kingdom, India, and Australia.
How to Say It and Where It Comes From
The spelling catches almost everyone the first time. It looks like it should have two or three syllables, but the silent letters are a holdover from French, and the modern pronunciation is simply “puny.”
The word came into English legal use from Anglo-Norman “puisné,” built from “puis” (after) and “né” (born). In its original sense it described a younger sibling or a later arrival in a family line. Courts borrowed the idea to rank judges by seniority on the same bench: a judge appointed after the chief justice was, literally, born later into that court’s membership.
What a Puisne Judge Does
A puisne judge sits as a full member of the court. The power to hear cases, decide them, and shape the law is identical to the chief justice’s. On a multi-judge panel, each vote counts the same regardless of title. No litigant gets a lesser form of justice because a puisne judge heard their case rather than the chief.
What puisne judges generally do not do is run the court. The chief justice handles scheduling, oversees the budget, represents the judiciary in dealings with the other branches of government, and assigns cases to panels. Puisne judges focus on the judicial work itself.
Pay reflects that split in duties. On the U.S. Supreme Court, the Chief Justice earns $320,700 a year while each Associate Justice earns $306,600, a gap of roughly 4.4 percent.1Federal Judicial Center.

Where the Title Is Used Today
The term remains a living part of legal language in several countries whose courts grew out of English law, though how prominent it is varies.
Canada
Canada’s Supreme Court Act structures the court as “a chief justice to be called the Chief Justice of Canada, and eight puisne judges.”2Department of Justice Canada. Supreme Court Act The statute uses “puisne” throughout, including in the oath of office and in the rules for who convenes the court when the Chief Justice is absent (seniority among the puisne judges decides that). The term is embedded in how the country’s highest court actually operates.
United Kingdom
The Supreme Court of Judicature Act 1873 referenced the existing “Puisne Justices” of the Courts of Queen’s Bench and Common Pleas as they moved into the newly unified High Court of Justice.3vLex United Kingdom. Supreme Court of Judicature Act 1873 High Court judges in England and Wales are still formally classified this way in legislation, though in everyday use lawyers and the public say “Justice” or address the judge as “Mr./Mrs. Justice.”
India
Indian courts picked up the term through the colonial legal system, and it persists in constitutional and judicial language. The Supreme Court of India and the various High Courts have used “puisne judges” in formal opinions and appointment orders to distinguish the Chief Justice from the rest of the bench. Article 217 of the Constitution covers the appointment of High Court judges without using the word itself, but the structural concept is the same, and judicial opinions routinely apply the term.
Australia
Australia still uses the title in official documents. In January 2026, the South Australian Government Gazette recorded the appointment of “a Puisne Judge of the Supreme Court of South Australia” to the Court of Appeal, citing the Supreme Court Act 1935.4South Australian Government Gazette. South Australian Government Gazette No. 3 The formal phrasing turns up in appointment instruments and judicial commissions, even as everyday courtroom practice runs on plainer titles.
Where the Word Has Faded
Not every common-law jurisdiction kept the word. Hong Kong’s judiciary lists its High Court members as “Judges of the Court of First Instance” and “Justices of Appeal” without any reference to “puisne.” Even where the term remains in statute, oral usage has thinned out. A lawyer at the High Court in London or a provincial superior court in Canada will almost always say “Justice” rather than “puisne judge” in argument. The word lives mostly in appointment documents, gazettes, and statutory text.
The American Equivalent
American courts do not use “puisne,” but they have the same structural idea. On the U.S. Supreme Court, eight Associate Justices sit alongside the Chief Justice, each exercising the full judicial power of the Court. Federal circuit and district courts follow the same pattern: a chief judge handles administration while the other judges concentrate on deciding cases. The titles differ by country, but the underlying design is the same everywhere: one judge runs the institution, and the rest do the judging.
For anyone reading older case law, colonial-era legal records, or current Commonwealth legislation, knowing what “puisne” means is essential to following who held what role on the court.
