A master is a judge in the courts of England and in numerous other jurisdictions based on the common law tradition. A master's jurisdiction is generally confined to civil proceedings and is a subset of that of a justice. Masters are typically involved in hearing trials, case management, and in some jurisdictions dispute resolution or adjudication of specific issues referred by judges.
Besides the courts of England and Wales, masters may be found in the Republic of Ireland, Australia, New Zealand, Hong Kong, several Caribbean countries and a number of Canadian provinces. Several state courts in the United States utilize masters or similar officers and also make extensive use of special masters.
Judicial officials exercising a master's jurisdiction are in some jurisdictions referred to as Registrars and Deputy Registrars.
In England and Wales a master is a sworn judge in the High Court having a jurisdiction similar to that of a Justice of the High Court in civil matters within the division of the court to which the master is appointed. The role of a master in the High Court of Justice of England and Wales is concerned primarily with trial and case management of High Court civil claims in London excluding committals to prison, judicial review and criminal cases. There are masters in the Queen's Bench and Chancery Divisions and the Costs Office (Taxing Masters/Costs Judges) and their roles differ slightly.
Such a person is addressed in court as, for example, "Master Smith". This is so whether the master is male or female, or as either 'Master' or 'Judge'. A similar type of master exists in the Court system of Northern Ireland, in several Canadian and Australian jurisdictions as well as in other countries whose court system is based on that of England.
The office of master is of ancient origins dating from at least the 12th century, though masters in Chancery were abolished in the 19th century and a new office of Chancery Master was recreated later. There are masters in the Chancery and Queen's Bench divisions of the High Court of Justice and the Costs Office of the High Court. The Senior Master of the Queen's Bench Division also bears the title of Queen's Remembrancer which is one of the oldest judicial offices in England.
In the Inns of Court, the members of the governing body are known as "Masters of the Bench" or, more commonly, "benchers". In the context of the functions they perform in that capacity (but not otherwise) they will be known as, for example, "Master Smith" (whether they are male or female). This will be so even if in other contexts they use a higher title: hence, a High Court Judge who is a Master of the Bench will be known in his or her Inn as "Master Smith", in private life as Sir John Smith, and on the bench as Mr Justice Smith; likewise a law lord will be known in the inn as "Master Woolf" even if he is privately and professionally known by the peerage title of "Lord Woolf".
In Canada the structure of the court system is primarily a provincial responsibility and the superior courts of the provinces have different names. Masters are found in the Supreme Court of British Columbia, Court of Queen's Bench of Alberta, the Court of Queen's Bench of Manitoba and the Ontario Superior Court of Justice. There are part-time taxing masters in the Supreme Court of Newfoundland and Labrador. There is a similar office of prothonotary in the Supreme Court of Prince Edward Island and in the Federal Court.
The jurisdiction of a Master is fixed by provincial statute and the rules of court. Masters are appointed by the provincial government. As a result, while Masters sit in a superior court, they do not have the "inherent jurisdiction" of the judges of those courts, who are appointed by the federal government and whose authority is derived from the Constitution of Canada and the Crown. Their jurisdiction is usually limited to procedural and Interlocutory matters heard in chambers. Consequently, though of the superior court, Masters are concurrently subordinate to the judges of that court insofar as application of judicial precedent is concerned. Masters commonly also sit as Registrars in Bankruptcy.
In the Federal Court of Canada, a judicial officer with much the same powers as a Master is called a Prothonotary.
Traditionally a Master is referred to as "Master Smith" or, in court, as "Master". In some jurisdictions, Masters are now referred to as "your honour".
Masters and Prothonotaries are independent judicial officers although they do not have the full level of security of tenure afforded to federally appointed judges.
In Alberta, British Columbia and Manitoba, masters have the same terms of appointment as provincial judges. This was formerly the case in Ontario as well but after the High Court of Justice and District Courts were merged, in 1986 a new office of Case Management Master was created.
In Ontario Case Management Masters have all of the authority of traditional masters as well as additional jurisdiction to manage actions and engage in dispute resolution processes. They are appointed by Order in Council and can only be removed for cause by the Chief Justice following a formal disciplinary process.
In Ontario the distinction between "chambers" and "court" has been abolished. When masters preside they sit as the court and their function is to perform tasks that would otherwise fall to superior court judges. Besides the jurisdiction to hear most interlocutory motions in civil matters, case management masters in Ontario also preside at status hearings, case conferences and pre-trials. They frequently act as referees to hear trials in construction lien matters, mortgage references or issues referred by judges. Case management masters also provide dispute resolution services and sit as Registrars in Bankruptcy.
In the High Court of New Zealand, Associate Judges perform the same role as Masters in the High Court of Justice in England and Wales. They were previously referred to as Masters, however the title was changed on 20 May 2004, and all existing Masters were renamed Associate Judges.
The Masters are the junior judges on the High Court of Fiji.
Contrary to a misconception sometimes held, neither the Master of the High Court nor the Taxing Masters are members of the judiciary. They are what are known as quasi-judicial office holders.
