Definition
An archaic Anglo-Norman law French term meaning one who disturbs or causes a disturbance. In its historical legal context, *desturber* referred to a person who interfered with another's lawful possession, enjoyment of rights, or the orderly exercise of legal proceedings. The term belongs to the vocabulary of early English common law, where law French served as the working language of the courts, and appears in records and treatises dealing with interference with rights of way, common, or other property interests.
Why It Matters in Research
Researchers encountering *desturber* will find it almost exclusively in early English legal sources — medieval plea rolls, Year Books, and early common law treatises composed in or heavily influenced by law French. The term is a direct transliteration of the Anglo-Norman verb *desturber* (to disturb), and its English equivalent, *disturber*, replaced it as legal English displaced law French from courtroom practice after the mid-seventeenth century. Any researcher working in pre-modern English common law records should treat *desturber* and *disturber* as functionally identical and cross-search both forms when indexing or keyword-searching manuscript sources or early printed treatises.
The term connects to a cluster of medieval property and nuisance concepts: disturbance of common rights (*disturbance of common*), obstruction of ways, and interference with the right to hold courts. In those contexts, the *desturber* was the party against whom a writ or action lay, making the term a forensic label rather than a substantive legal category of its own.
Historical Dictionary Support
Burrill's Law Dictionary provides the entry in its minimal form: "L. Fr. To disturb. Desturbe; disturbed. Britt. c. 32." The reference to *Britton* (c. 32) anchors the term in one of the foundational Anglo-Norman legal texts of the late thirteenth century, a vernacular abridgment of English law written in law French and attributed to the reign of Edward I. Burrill offers no substantive elaboration, treating the term as a simple lexical gloss rather than a developed legal concept.
This reflects the broader treatment of law French vocabulary in nineteenth-century legal dictionaries: such terms were catalogued as linguistic curiosities or translation aids rather than living doctrinal categories. No significant divergence exists among historical sources on this term because the term itself had largely ceased to appear in active legal usage long before systematic legal lexicography began. The entry survives in dictionaries like Burrill's primarily as a service to readers attempting to parse archaic source texts, not as guidance on operative law.
Researchers should note that *Britton* itself is available in edited and translated editions, and the reference to chapter 32 may assist in locating the precise passage where *desturber* appears in context — a more productive route than relying on dictionary glosses alone.
Jurisdictional Note
The term is specific to early English common law and has no recognized usage in American, Scottish, or civilian legal traditions. It does not appear in operative legal texts in any jurisdiction today.
