Definition
The Crown Office was the administrative department of the Court of King's Bench (or Queen's Bench, depending on the reigning monarch) responsible for the court's criminal jurisdiction. It constituted what practitioners and commentators called the "crown side" of the court — the division through which the court exercised its authority over criminal matters ranging from high treason down through misdemeanors and breaches of the peace.
The term carries two related but distinct meanings:
1. The Crown Office as a court department. A standing office within King's/Queen's Bench that received, processed, and managed criminal proceedings on the crown side of the court. Criminal informations — including those filed by the Attorney General and the Master of the Crown Office — were initiated and administered through this office.
2. The Master of the Crown Office. The title of the king's (or queen's) principal attorney attached to this department, who held authority to file criminal informations on behalf of the Crown. References to "the crown office" in older English legal texts sometimes serve as shorthand for the officer as much as the institution.
Common Language
Modern common usage (Wiktionary): No standard entry. The phrase is not in active civilian use.
Historical common usage (Webster's 1913): "The criminal branch of the Court of King's or Queen's Bench, commonly called the crown side of the court, which takes cognizance of all criminal cases."
Webster's 1913 tracks the legal meaning almost precisely, drawing directly from Burrill. There is no meaningful gap between common and legal usage here — the term had no life outside its legal institutional context and Webster simply imported the legal definition. Researchers should treat the Webster's entry as a restatement of legal sources, not an independent gloss.
Recognized Forms
/SUBTYPES
Crown Side / Crown Office (institutional): The criminal department of King's/Queen's Bench as a whole.
Master of the Crown Office: The designated officer empowered to file criminal informations. Distinct from the Attorney General, though both could file informations through the Crown Office. Historical sources sometimes conflate these roles or use the institutional name to refer to the officer.
Why It Matters in Research
This term is historically specific to English common law courts and has no direct American counterpart. Researchers working in pre-19th century English legal sources, colonial American materials, or early republic documents that invoke English practice will encounter Crown Office most often in discussions of criminal informations — the procedural mechanism by which prosecutions were initiated on the crown side without a grand jury indictment.
The critical research trap is chronological: the office and its functions were substantially altered by 19th century English court reform, particularly by the Judicature Acts of the 1870s, which reorganized the superior courts of England and Wales. After consolidation, references to the "crown side of Queen's Bench" persist in older treatises but the institutional Crown Office as a freestanding department effectively dissolved into the reformed court structure. A source citing the Crown Office after 1875 is almost certainly referring to pre-reform practice or historical doctrine, not a contemporaneous institution.
A second trap is terminological slippage between the office and the officer. When Blackstone, Burrill, or other commentators write that "the master of the crown office" filed an information, they are describing an officer acting through an institution. When they write that "the crown office" received the information, they describe the institution. Researchers reading quickly may miss that both phrases often appear in the same passage with different referents.
American researchers should note that colonial and early federal courts sometimes gestured toward Crown Office practice when discussing criminal informations, but the United States never institutionalized a direct equivalent. The debate over whether federal courts could entertain common law criminal informations — without grand jury indictment — was live in the early republic and distinct from the English Crown Office framework.
Historical Dictionary Support
Black's and Bouvier's give nearly identical one-sentence definitions, both citing 4 Blackstone's Commentaries 308. This convergence reflects mutual copying rather than independent analysis — a common pattern in 19th century American legal dictionaries when describing English institutional history. Neither source engages with the office's procedural function or the role of the Master.
Burrill's is the most substantive of the historical entries. It distinguishes the Crown Office as a department from the "crown side" of the court, notes the range of criminal jurisdiction (high treason to trivial misdemeanor), and specifically identifies the mechanism of criminal informations filed by both the Attorney General and the Master of the Crown Office. Burrill cites 4 Blackstone's Commentaries 265, 4 Stephen's Commentaries 326, and Cole on Criminal Informations — the last being a genuine English treatise on that procedural device. Researchers needing depth should begin with Burrill and then move to the primary Blackstone and Stephen passages.
Rapalje & Lawrence's entry for this term is not usable — the text provided appears to be a misfiled passage from a separate entry (relating to bills, banking, and ship damage), likely a digitization error in the corpus. Researchers should not rely on Rapalje & Lawrence for this term without consulting the original print edition.
Jurisdictional Note
The Crown Office was an institution of English law with no direct American equivalent. Its procedures and the criminal informations processed through it informed early American debates about grand jury requirements and prosecutorial authority, but those connections are doctrinal and historical rather than institutional. Researchers working in Scottish, Irish, or colonial legal sources should verify whether local courts adopted analogous terminology, as usage was not uniform across the British legal world.
