Definition
Law French. Literally, "does not disturb" or "did not disturb." Ne disturba pas is the general issue plea in a quare impedit action — the formal denial by which a defendant contests the plaintiff's right to present a candidate to a benefice or other advowson. By pleading ne disturba pas, the defendant puts the entire claim in issue, denying that any disturbance occurred in the manner and form alleged. It is the standard, broad-scope plea in this now-obsolete form of English ecclesiastical and common-law pleading.
Common Confusion
Ne disturba pas is sometimes grouped casually with other Law French general-issue pleas as if they were interchangeable. They are not. Each is tied to a specific writ or action:
— Ne disturba pas belongs to quare impedit, an action to recover the right of presentation to a church living or other advowson when a patron has been wrongfully disturbed.
— Ne dona pas (or non dedit) is the general issue in formedon, an action to recover lands entailed by gift. It denies that the gift in tail was made in the manner alleged. The two pleas address entirely different subject matters and cannot be substituted for one another.
Researchers encountering either plea in historical records should first identify the underlying writ before drawing any inference about the nature of the dispute.
Why It Matters in Research
Ne disturba pas is encountered almost exclusively in pre-nineteenth-century English ecclesiastical and common-law records. Quare impedit as a practical action was largely superseded after the Judicature Acts and associated reforms dismantled the old forms of action in the latter half of the nineteenth century. American researchers will rarely if ever encounter this plea in domestic sources; it is a creature of English practice with no significant transplant to colonial or early American procedure.
For Law Mind corpus researchers, the term surfaces primarily in pleading treatises, abridgments, and Year Book-era materials. Stephen's Commentaries and Wooddeson's Lectures are the core secondary sources. The plea appears in entries near ne dona pas in most historical dictionaries, which can cause indexing confusion — a researcher scanning Bouvier or Black's for one term will find the other immediately adjacent, and the two are editorially distinct entries that historical compilers occasionally blurred.
The practical significance for historical research is narrow but precise: finding ne disturba pas in a pleading record locates the dispute squarely in the law of advowson and ecclesiastical patronage — questions of who held the right to nominate a clergyman to a vacant living. This connects to a web of property, church, and crown law that is otherwise difficult to navigate without familiarity with the underlying action.
Historical Dictionary Support
All four source dictionaries agree on the core definition: Law French for "does not disturb," functioning as the general issue in quare impedit. The definitions are substantially identical across Black's (both editions) and Burrill, all citing Stephen's Commentaries (3 Steph. Comm. 663) as authority. Burrill adds citations to Stephen's Pleading and Wooddeson's Lectures, providing a slightly fuller bibliographic trail for researchers who need to locate the original procedural context.
Bouvier's entry is the leanest, citing Hobart's Reports (Hob. 162) and a cluster of entry books, and directing readers to Andrews and Stephen on Pleading. Bouvier does not translate the phrase explicitly, which reflects his tendency to assume reader familiarity with Law French. None of the historical dictionaries explain the underlying writ of quare impedit in the ne disturba pas entry itself, meaning a researcher relying solely on these definitions without tracing the cross-references will lack the substantive context needed to interpret a document containing the plea.
All four sources place ne dona pas or non dedit immediately adjacent to ne disturba pas in their entries, reinforcing the importance of not conflating the two. The truncation in some editions of Black's (where the ne dona pas entry appears to be cut mid-sentence) is an artifact of the dictionary's formatting, not an incomplete legal doctrine.
Jurisdictional Note
This plea is a product of English ecclesiastical and common-law practice with no meaningful American counterpart. The writ of quare impedit was never significantly adopted in the United States, where the separation of church and state eliminated the legal infrastructure — church livings, advowsons, rights of presentation — that the plea presupposes.
