Definition
Latin. "A vexed question." A legal question or point of law that has been repeatedly argued, debated, or litigated without reaching a settled or authoritative resolution. A vexata quaestio is not merely an open question — it is one that has been actively contested, has attracted conflicting decisions or opinions, and remains genuinely doubtful despite sustained attention. The term carries the implication that the uncertainty is not from neglect but from the inherent difficulty of the point, or from irreconcilable conflict among courts and commentators.

Common Language
Modern common usage (Wiktionary): "Vexed" in ordinary English means troubled, annoyed, or (of a question) difficult and much debated.
Historical common usage (Webster's 1913): "Vexed" — much debated or contested; as, a vexed question.
The ordinary English meaning of "vexed question" captures the flavor reasonably well, but the legal term carries a more precise institutional weight: it signals not merely that a question is difficult or controversial, but that courts and legal authorities have specifically engaged with it on multiple occasions and reached divergent outcomes. A vexata quaestio is a term of art signaling doctrinal instability, not just intellectual difficulty.

Common Confusion
Vexata quaestio is sometimes treated as equivalent to res integra (a point never before decided) or to obiter dictum (an unresolved observation made in passing). These are distinct concepts. Res integra refers to a question that has not yet been adjudicated at all. Vexata quaestio refers to one that has been adjudicated repeatedly but without consistency or finality. A point may begin as res integra, generate conflicting decisions, and thereby become a vexata quaestio. The two terms describe opposite ends of the same spectrum of legal uncertainty.

Why It Matters in Research
Researchers encountering vexata quaestio in historical sources should treat it as a red flag for doctrinal instability. When a court or treatise writer labels a question a vexata quaestio, it is a direct signal that the surrounding authorities will likely be in tension and that synthesis requires care.
In older common law sources — particularly English reports from the sixteenth through nineteenth centuries — the phrase appears with some frequency as a rhetorical marker. It was used by judges and writers to acknowledge openly that they were entering contested territory, and sometimes to excuse a departure from prior authority. Researchers should not read it as an admission of ignorance; it was often a deliberate framing device to justify a fresh analysis or a break from an inconvenient line of cases.
The citations given in Black's — 7 Coke and 8 Burrows — locate the phrase firmly in the classical English common law tradition. Researchers working in early American law should note that American courts inherited both the phrase and its rhetorical function, but its appearance in American reports grows rarer through the nineteenth century as the Latin legal vocabulary was progressively replaced by plain English equivalents.
When searching digitized historical sources, note the spelling variation: the term appears as both quaestio and questio (and occasionally in corrupted forms like the "quzstio" variant, which is a transcription artifact, not an accepted alternative spelling). Searches limited to one spelling will miss instances of the other.
For corpus researchers, vexata quaestio functions as a useful marker for locating exactly those legal questions that generated the most persistent doctrinal conflict in a given period. Its presence in a source is itself evidence of the state of legal uncertainty at the time of writing.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) defines vexata quaestio as "a vexed question; a question often agitated or discussed, but not determined or settled; a question or point which has been differently determined, and so left doubtful," citing 7 Coke and 8 Burrows.
Black's definition is accurate and serviceable. Its emphasis on the question having been "differently determined" is the most legally precise element — it is the conflict among determinations, not merely the absence of resolution, that makes a question a vexata quaestio in the full technical sense.
No other entries in the current source set treat this term. The historical legal dictionaries of Bouvier and Burrill would be natural sources to consult for additional nuance; their absence here limits comparison. It is worth noting that the term received more attention in English legal literature than in American, and American dictionaries of the nineteenth century tend either to omit it or reproduce the Coke-era formulation without elaboration. The term's longevity in legal usage owes more to its precision as a descriptive label than to any formal doctrinal role it plays in legal analysis.

Jurisdictional Note
The term has no jurisdiction-specific legal definition. Its use and meaning are consistent across common law jurisdictions wherever Latin legal vocabulary persisted. It is more frequently encountered in English sources than American, and more common in sources predating the twentieth century than in modern materials.
