Definition
A special examiner is a person appointed by a court — historically a court of equity — to take testimony or conduct an examination in a specific, individual case, as distinguished from a standing examiner who serves the court generally. The appointment is case-specific and terminates upon completion of the assigned proceeding or task.
In English equity practice, a special examiner was someone outside the ordinary roster of the court's examiners, commissioned for a particular suit. In American practice, the term carried forward into federal and state procedural rules to describe a person — often a notary, commissioner, or other qualified officer — appointed by a court or by agreement of the parties to take depositions or hear testimony outside the courtroom when regular court officers are unavailable or when the circumstances of witnesses make ordinary procedure impractical.
Common Confusion
SPECIAL EXAMINER vs. MASTER / COMMISSIONER / REFEREE: These roles overlap significantly and are frequently conflated. A master or referee typically has broader authority — the power to hear an entire matter, receive evidence, make findings, and report recommendations to the court. A special examiner's function is narrower: principally the taking of testimony or supervising an examination in a particular proceeding. In modern federal practice, much of what a special examiner once did is now handled under the master or magistrate framework, which means older procedural sources using "special examiner" may be describing a function now subsumed under a different title.
SPECIAL EXAMINER vs. EXAMINER IN CHANCERY: An examiner in chancery was a permanent court officer whose standing duties included taking witness testimony for the court. A special examiner was the ad hoc alternative — appointed specifically because the regular examiner was unavailable, overloaded, or geographically unsuitable. The distinction matters when reading historical equity records: references to "the examiner" indicate a standing officer; references to "a special examiner" indicate a case-specific appointment.
Why It Matters in Research
Researchers will encounter this term most heavily in pre-twentieth-century equity materials, English Chancery records, and early federal equity practice under the Equity Rules that preceded the Federal Rules of Civil Procedure (1938). After 1938, the procedural vocabulary shifted: the FRCP absorbed much of equity procedure into unified civil procedure, and the roles of master, magistrate, and notary displaced the special examiner label in formal federal usage.
Three navigational traps:
First, historical sources are inconsistent about what authority a special examiner held beyond taking testimony. Some treatises suggest the appointment was strictly ministerial — the examiner received testimony but made no rulings. Others describe appointments with broader powers closer to a commissioner or master. The scope depended heavily on the appointing court's order, so researchers should locate the actual order of appointment in the record, not infer scope from the title alone.
Second, the term survives in some state court rules and administrative contexts with meanings that differ from the historical equity sense. Administrative agencies, licensing boards, and state courts occasionally use "special examiner" to describe a hearing officer or investigator. Context determines meaning; the historical equity definition should not be assumed to control modern state administrative usage.
Third, in patent practice and some specialized federal proceedings, "special examiner" has appeared as a term for a USPTO official or a court-appointed expert conducting a technical examination — a usage unconnected to the equity tradition. Cross-referencing the procedural context is essential.
Historical Dictionary Support
Black's and Bouvier's agree on the essential core: a special examiner is a court-appointed examiner in a specific case, distinguished from the regular examiners attached to the court. Black's grounds the definition explicitly in English Chancery practice, noting two practical triggers for the appointment — congestion in the examiner's office and the inability of witnesses to travel to London. This geographic dimension is worth noting: it reflects an era when taking testimony in person before a standing court officer was the default, and physical distance was a genuine procedural obstacle. Bouvier's is briefer and cross-references Examiners in Chancery, correctly signaling that the two terms are best understood in relation to each other.
Neither historical source addresses the American procedural life of the term with any depth, and neither anticipates its partial absorption into the master and magistrate framework under modern unified civil procedure. Researchers relying solely on these definitions will have a sound understanding of the historical English equity context but will need to consult procedural rule histories and treatises on federal equity practice for the American development.
Jurisdictional Note
The term is most definitively rooted in English Chancery and early American equity courts. In modern federal practice it has largely been displaced by the master and magistrate terminology of the Federal Rules. Some state courts and administrative bodies retain the label, but its meaning in those contexts should be verified against the specific governing rules rather than assumed from the historical definition.
