Definition
Latin phrase meaning "whichever way you take it" or "in whichever view of the case." Used in legal argument and judicial reasoning to express that a conclusion holds regardless of which interpretation, theory, or approach is applied to a given set of facts or legal question. When a court or advocate invokes quacunque via data, the point is that the outcome is the same across all plausible analytical paths — no matter how the problem is framed, the same result follows. It functions as a rhetorical and logical device, not a substantive legal doctrine.

Why It Matters in Research
Quacunque via data appears most often in older common law opinions and treatises as a shorthand signal that a judge or advocate has considered alternative grounds and found them to converge. Researchers encountering the phrase in historical case reports should read it as an instruction to look backward in the opinion for the alternative theories being collapsed — the phrase typically concludes an analysis rather than opening one.
The phrase is associated with Lord Mansfield's era and the style of eighteenth- and early nineteenth-century common law reasoning, when Latin maxims carried significant rhetorical weight in court. Its frequency declines sharply in American opinions after the mid-nineteenth century as courts moved away from Latinate argumentation. By the time of the later Black's editions, it had become a dictionary artifact rather than active judicial vocabulary.
Researchers using the Law Mind corpus should note that this term will surface primarily in pre-Civil War American reports and English common law materials. Finding it in a mid-to-late nineteenth century American opinion is notable and may signal a court drawing on older English authority or a particularly classically trained advocate. It will rarely appear in twentieth-century sources except in historical or comparative legal writing.
Because the phrase signals logical redundancy in the argument — that multiple grounds support the same conclusion — it can also be a useful marker when tracing how courts handled cases involving overlapping theories of liability or competing interpretations of a deed or contract. Shepard's Touchstone (cited by Burrill) was a standard conveyancing reference, which suggests the phrase appeared in property law contexts where instruments might be construed under more than one rule of construction.

Historical Dictionary Support
The historical sources are in close agreement on translation and meaning, with Burrill's providing the most useful research context. All four dictionaries render the phrase as some variation of "whichever way you take it," with Burrill's adding the functionally important gloss "in whichever view of the case" — a clarification that shifts the term from a purely rhetorical flourish to a description of how courts handled multi-theory analysis.
Burrill's is also the only source to supply legal citations, attributing usage to Lord Mansfield (2 Burr. 980) and Justice Story (2 Gallison's R. 26; 1 Gallison's R. 637), as well as 11 Metcalf's R. 276 and Sheppard's Touchstone at page 367. These citations are genuinely instructive: Story's use of the phrase in the circuit reports confirms its migration into early American federal jurisprudence, and the Metcalf citation places it in Massachusetts common law. The Sheppard's Touchstone reference grounds it in the conveyancing tradition.
Black's (both editions) and Rapalje & Lawrence treat it as a simple vocabulary entry requiring no elaboration, which reflects the phrase's status by the late nineteenth century — well understood by trained lawyers, needing no explanation, but no longer a live analytical tool requiring definition.
What the historical sources collectively miss is any discussion of how the phrase functions argumentatively, or what its presence in an opinion signals about the structure of the reasoning. Burrill's comes closest by supplying citations, but none of the sources address the phrase as a rhetorical or logical device in the way modern readers might find most useful.
