Definition
An old English legal term meaning "the right of bench." Jus banci denoted the right or privilege of a judge to occupy an elevated, separate seat of judgment — the physical bench — from which royal justice was administered. Historically, this privilege was reserved exclusively to the king's judges, who by virtue of holding it were said to administer high justice (summam administrant justitiam), as distinguished from inferior forms of adjudication exercised by lesser tribunals or officials.
The term is essentially a relic of the formal architecture of English feudal courts, where the physical elevation of the bench was not merely ceremonial but carried legal and jurisdictional significance. To hold jus banci was to hold a position from which the highest order of justice could be rendered in the king's name.
Why It Matters in Research
Jus banci is a narrow, archaic term unlikely to appear outside historical legal sources, old English treatises, or scholarship on the development of royal courts. Researchers encountering it should understand it as a marker of jurisdictional hierarchy rather than a freestanding doctrine: the term signals the distinction between courts of high justice (the king's courts exercising full adjudicatory authority) and inferior or delegated tribunals.
The primary trap for corpus researchers is confusing jus banci with related Latin phrases about judicial authority or bench procedure. The term is specifically about the right to occupy the elevated bench — not about jurisdiction in the modern sense, and not about any procedural power exercised from that bench. It describes a status or entitlement, not a rule of law.
The sole attributed authority across all three source dictionaries is Blount — Thomas Blount's Nomo-Lexicon: A Law-Dictionary (1670), one of the foundational historical English law dictionaries. Researchers tracing this term through the corpus should expect Blount's Nomo-Lexicon to be the original or near-original source and should not expect independent elaboration in later common law materials. The term did not develop a significant doctrinal life beyond its descriptive use in legal glossaries.
Because jus banci speaks to the structural hierarchy of English judicial institutions, it may surface in historical scholarship on the Court of King's Bench, the development of the common law bench, or comparative studies of feudal court organization. Researchers working in those areas should treat it as context for understanding why the king's judges held a categorically different status from local or manorial adjudicators.
Historical Dictionary Support
All three source dictionaries — Black's (1st Ed.), Black's (2nd Ed.), and Burrill's — are in complete agreement, reproducing nearly identical definitions with only minor typographical variation. All three trace the term to Blount. Burrill adds the precise citation "Blount, voc. Bank," confirming the entry appears under "Bank" in Blount's Nomo-Lexicon, which is useful for researchers seeking the primary source.
None of the historical dictionaries expand on jus banci beyond its basic gloss. There is no treatment of how the concept interacted with specific courts, no case law cited, and no discussion of when or how the privilege was formally recognized or extinguished. This uniformity reflects the term's status as a learned archaism preserved in legal dictionaries rather than a living doctrine with ongoing application. The absence of elaboration is itself informative: by the time Black's was compiled, jus banci had no practical legal significance and was retained in the dictionary record primarily for historical completeness.
