Definition
An obsolete writ directed to the sheriff commanding the levy of expenses owed to every citizen and burgess attending parliament. The writ provided a mechanism for members of parliament to recover the costs of their attendance — travel, lodging, and related charges — by authorizing the sheriff to collect those sums from the constituency the member represented. It belongs to the medieval English parliamentary apparatus and has no functional equivalent in modern law.
Why It Matters in Research
GENSIUM is a dead-end term for practical modern legal research but a useful marker for researchers working in medieval English constitutional history, parliamentary procedure, or the history of legislative compensation. Its appearance in a source signals a document firmly rooted in early English parliamentary practice. Researchers tracing the historical foundations of legislative pay and expense reimbursement may encounter the writ in antiquarian treatments of parliament, though it will not appear in post-medieval case law or statute. The sole significant primary reference is Coke's Institutes (4 Inst. 46), and researchers should expect the term to surface almost exclusively in sources drawing on Coke directly. Do not expect cross-references in American legal materials; the writ was never transplanted to colonial or post-independence legal systems.
Historical Dictionary Support
Black's Law Dictionary provides the only dictionary entry of note, drawing directly on Coke's Fourth Institutes at page 46. The entry is brief and purely descriptive, characterizing the writ as obsolete and offering no doctrinal elaboration. No substantive divergence exists across editions of Black's because there is simply no doctrinal content to develop — the writ died with the medieval parliamentary practice it served. Historical legal dictionaries uniformly treat this as a relic term requiring only identification, not analysis. The institutional context — that members of early English parliaments were compensated by their constituencies rather than the crown, and that a writ of this kind was necessary to enforce collection — is essential background for understanding why the writ existed at all, but that context must be drawn from parliamentary histories rather than legal dictionaries, which offer none of it.
Jurisdictional Note
Strictly English in origin and application. Never received into American, Scottish, or other common law jurisdictions. Research is limited to English legal history prior to the obsolescence of constituency-funded parliamentary attendance.
