Definition
De officio coronatoris (Latin: "concerning the office of coroner") is the title of an English statute enacted under Edward I, dating to approximately 1275–1276, that formally enumerated and defined the duties of the coroner's office. The statute codified what had previously existed as a mixture of custom, royal command, and common law expectation, giving the coroner's functions their first comprehensive statutory expression in English legal history. It established the coroner as a Crown officer responsible for inquiring into sudden, suspicious, or violent deaths; recording treasure trove findings; and performing other duties tied to the financial and judicial interests of the Crown.
Why It Matters in Research
This term functions almost exclusively as a bibliographic and historical citation marker rather than a term of living legal doctrine. Researchers encountering it in historical texts should treat it as a pointer to a specific statute — 4 Edward I — rather than to a general legal concept.
Several navigational points are worth flagging:
First, de officio coronatoris is typically encountered in secondary historical treatments of English legal development, not in primary legal argumentation. When Reeves, Blackstone, or similar historians reference it, they are tracing the institutional lineage of the coroner's office, not invoking the statute as operative authority.
Second, the statute sits within a cluster of Edwardian legislation — including the Statute of Westminster I (1275) and Westminster II (1285) — that collectively reformed English administrative and judicial structures. Researchers working on the coroner's office in this period need to situate de officio coronatoris within that broader legislative context rather than reading it in isolation.
Third, the coroner's office underwent substantial transformation between the thirteenth century and the modern era. The duties enumerated in 4 Edward I — including the coroner's role in preserving Crown revenue from forfeiture proceedings and amercements — largely dropped away as the office narrowed to death investigation. A researcher tracing the modern coroner's statutory authority back through historical sources will find a significant gap between de officio coronatoris and contemporary coroner statutes; the institutional continuity is real, but the functional scope is not.
Fourth, Latin statutory titles of this period are frequently abbreviated, misquoted, or paraphrased in historical digests and abridgments. Burrill cites to 2 Reeves' History of English Law, which itself is a secondary synthesis. Researchers needing the text of 4 Edward I should verify against primary statutory compilations rather than relying on derivative references.
Historical Dictionary Support
Burrill's Law Dictionary provides the core identification: de officio coronatoris is the title of 4 Edward I, with the cross-reference to Reeves' History of English Law at volume 2, page 140. This is the entry's complete treatment — Burrill does not elaborate on the statute's substantive provisions, treating the term as a bibliographic label.
What Burrill does not supply — and what researchers should not assume from the entry alone — is any account of the statute's contents. The statute addressed the coroner's obligation to hold inquests on the bodies of those slain or dying suddenly, to record appellors and approvers, to register sanctuary-seekers and those who abjured the realm, and to oversee treasure trove. These functions were intertwined with the Crown's financial interests as much as with any proto-criminal investigative purpose.
Historical dictionaries of this period generally handle de officio coronatoris by title only. No significant disagreement among historical sources exists on its identification; the dispute, if any, concerns the precise dating and scope of the statute relative to surrounding Edwardian legislation.
Jurisdictional Note
De officio coronatoris is a statute of English origin with no direct analog in other legal systems. Its relevance in American legal research is purely historical — useful for tracing the common law foundations of the coroner's office as it was received in colonial and early American law, but not operative authority in any U.S. jurisdiction.
