Definition
Latin phrase meaning "with one voice." Used in legal writing and court reports to indicate that a decision, judgment, or other formal action was taken unanimously — without dissent from any member of the body acting.
The phrase appears most often in older case reports and legal commentary to signal that a court's ruling was not merely a majority decision but a wholly undivided one. It is descriptive rather than operative: una voce characterizes the manner in which a result was reached, not the legal force of the result itself.

Common Language
Modern common usage (Wiktionary): "Una voce" does not appear as a standard English entry. The phrase is recognized in English primarily as a Latin borrowing retained in formal and ecclesiastical contexts, meaning "with one voice" or "unanimously."
Historical common usage (Webster's 1913): Not listed as a standalone entry. The constituent words — una (one) and voce (voice) — derive from classical Latin and were understood by any educated reader of the period.
The phrase carries no gap between its literal and legal meanings: law borrowed the Latin directly and used it without modification. The interest for researchers is not semantic drift but rather the phrase's near-complete disappearance from modern legal writing, having been replaced by the plain English "unanimously."

Why It Matters in Research
Researchers will encounter una voce almost exclusively in English common law reports and legal texts from roughly the seventeenth through the nineteenth century. It is a period marker: its presence in a source signals older case law or commentary. When reading early English reporters — Hobart, Coke, Dyer, Saunders, and their contemporaries — una voce appears with some frequency as a shorthand notation that a full bench agreed.
Two navigational traps are worth flagging. First, the phrase tells you the vote was unanimous, but not which judges voted, how many sat, or whether any recused. A court ruling una voce in a panel of three looks identical in the reports to a full bench ruling una voce — the phrase does not supply the head count. Second, unanimity as reported in early English reporters occasionally reflected an era when dissenting opinions were not formally published even when they existed. A report reading una voce should be cross-checked against other accounts of the same case where multiple reporters covered it, as the underlying reality of judicial agreement sometimes differed from the published notation.
For researchers in the Law Mind corpus, una voce will appear as part of direct quotations, case summaries, and Latin maxim collections rather than in statutory or regulatory text. It is not a term of art that generates legal consequences — no doctrine turns on whether something was decided una voce versus by majority. Its value in research is contextual and bibliographic: it helps date a source, characterizes the strength of a precedent as reported, and flags that the underlying document is likely an early common law report rather than a modern authority.

Historical Dictionary Support
All four source dictionaries agree completely on meaning: "with one voice; unanimously; without dissent." There is no divergence across the shelf worth noting.
Burrill's Law Dictionary is the most useful of the four for research purposes because it supplies an actual usage example: "The court, unâ voce, gave judgment." with a citation to Hobart 129. This grounds the phrase in the real textual tradition and confirms it was used as a parenthetical characterization within a sentence of legal narration, not as a standalone heading or formal term of pleading.
Black's first edition contains what appears to be a transcription error in the source material — "der delusion, would make" — that is clearly corrupted text and should be disregarded. The corrected entry reads simply "with one voice; unanimously; without dissent," consistent with all other sources.
None of the historical dictionaries addresses the phrase's decline or its relationship to the development of formal dissenting opinions in Anglo-American courts, which is the more useful historical frame for a modern researcher encountering it.

Jurisdictional Note
Una voce is not a term of current legal operation in any U.S. jurisdiction. Its use was substantially confined to English legal literature and those American works that drew directly from English common law reporters. Scottish and continental European legal writing used the phrase in similar fashion.
