Definition
In English ecclesiastical law, perturbation is a technical term signifying the disturbance or infringement of a legally recognized right. Its primary legal application is to the disturbance of a person's right to occupy a specific pew or seat in a church. An action brought to remedy such an interference is called a suit for perturbation of seat, and was cognizable in the ecclesiastical courts of England. The term carries no significant meaning in modern secular civil or criminal law.
Common Language
Modern common usage (Wiktionary): Agitation; the state of being perturbed. Also used in scientific contexts to describe a small change in a physical or biological system, or a variation in an orbital path due to external forces.
Historical common usage (Webster's 1913): The act of perturbing, or the state of being perturbed; especially, agitation of mind. Also, in astronomy, a disturbance in the regular elliptic motion of a heavenly body caused by an additional force beyond that which governs its standard motion.
The gap is significant. In ordinary English, the word describes a mental or physical state of agitation — something experienced internally or observed in natural systems. In ecclesiastical law, it is a precise term of art describing an actionable interference with a property-like right attaching to a specific seat in a church. A researcher encountering the term in a legal source should not read it in its colloquial sense; it signals a formal cause of action, not a description of emotional or physical disturbance.
Why It Matters in Research
Researchers working in English legal history, ecclesiastical law, or church property will encounter this term almost exclusively in the context of pew rights litigation. The suit for perturbation of seat was a procedurally distinct action in the ecclesiastical courts, separate from the common law remedies available for trespass or nuisance. Understanding this distinction matters when tracing disputes that moved between ecclesiastical and civil jurisdictions, as rights to pews could also give rise to common law actions depending on the nature of the right asserted.
The term is largely dormant in modern legal sources. Its appearance in a legal document is a strong signal that the material dates to a period when ecclesiastical courts exercised active jurisdiction over church-related property rights in England — broadly, pre-1857 in matters of church discipline and property. Researchers should not expect to find it in American legal materials except as a borrowed technical phrase in early treatises drawing on English ecclesiastical practice.
Cross-referencing pew and seat in the corpus will yield the substantive law underlying these suits. Perturbation is the procedural or pleading term; pew and seat carry the underlying property doctrine.
Historical Dictionary Support
The historical dictionaries show strong agreement on the core definition and application. Bouvier offers the most complete treatment, describing perturbation as a technical word signifying disturbance or infringement of a right and noting its specific application to pews and seats in church. Burrill is concise but consistent, defining it as disturbance of pews or seats in a church within the category of ecclesiastical law. Black's (both editions) likewise confines the term to the suit for perturbation of seat and cites Phillimore's Ecclesiastical Law as the authoritative source, a reference Bouvier corroborates.
Rapalje and Lawrence do not offer a substantive entry on the term, which reflects the word's narrow jurisdictional footprint — primarily an English ecclesiastical law term with limited penetration into the American legal tradition that Rapalje and Lawrence more directly addresses.
None of the historical dictionaries address any potential secular or common law use of the term, which suggests the word was understood even by contemporary compilers as belonging exclusively to ecclesiastical practice. Researchers should treat any apparent secular usage of perturbation as either a borrowing from ecclesiastical vocabulary or an error in transcription.
Jurisdictional Note
This term is effectively English in origin and application. American ecclesiastical law never developed a formal parallel structure of ecclesiastical courts with civil jurisdiction, so suits for perturbation of seat have no direct American procedural equivalent. Disputes over pew rights in American jurisdictions were handled as common law property or contract matters. Researchers working in American sources will rarely encounter this term with legal force.
