Definition
VICE carries three distinct legal meanings, each functionally independent.
1. Defect or imperfection (substantive legal use). In the civil law tradition, a vice is a fault, defect, or imperfection in a thing — particularly in the subject matter of a sale or contract. The term appears most prominently in the doctrine of redhibitory vices: defects sufficiently serious to entitle a buyer to rescind the sale and recover the purchase price. A vice in this sense may be latent (hidden, unknown to the buyer) or apparent (observable on reasonable inspection), with different legal consequences attaching to each.
2. Latin preposition meaning "in place of" or "in the stead of." Used as a prefix in titles of office — vice-president, vice-chancellor, vice-admiral, vice-consul — to designate a deputy empowered to act for the principal officer in cases of absence, incapacity, or death. As a standalone Latin term, vice mea means "in my place."
3. Moral fault or habitual immoral conduct (general legal usage). In criminal law, regulatory law, and older equity jurisprudence, vice refers to immoral habits or practices — particularly those subject to statutory prohibition or police power regulation. Vice squads, vice crimes, and vice statutes use the term in this sense.
Common Language
Modern common usage (Wiktionary): Immoral or wicked behavior; a bad habit; also an alternative spelling of vise (the clamping tool), and historically a winding staircase or lead-drawing tool.
Historical common usage (Webster's 1913): "A moral fault or failing; especially, immoral conduct or habit, as in the indulgence of degrading appetites; customary deviation in a single respect, or in general, from a right standard." Also: "A defect; a fault; an error; a blemish; an imperfection."
The common meaning of vice (moral failing, bad habit) maps onto legal meaning 3 above, but the most technically precise legal use — the civil law doctrine of redhibitory vices — is invisible in ordinary English. A researcher encountering vice in a Louisiana purchase contract or a civil law treatise is reading a term of art about product defects, not moral character. The Latin prepositional use (meaning 2) is entirely absent from modern common usage.
Common Confusion
The three meanings of vice operate in completely separate doctrinal contexts but can produce confusion in historical sources that do not clearly signal which sense is intended. Most often: a reference to "vice" in a sales or property context almost certainly invokes the civil law defect doctrine, not moral conduct. Conversely, "vice" in criminal codes, police powers discussion, or equity (unclean hands, unconscionability) invokes the moral-fault sense. The Latin prepositional vice appearing in official titles or procedural documents is structurally distinct and should not be read as either of the other two meanings.
Redhibitory vice is also distinct from warranty of merchantability or fitness in common law jurisdictions — researchers accustomed to common law sales doctrine should not assume the concepts are identical.
Recognized Forms
/SUBTYPES
Redhibitory vice: A defect serious enough to justify rescission of the sale (redhibition) and return of the price. The benchmark is whether the buyer, had the defect been known, would not have purchased the thing at all, or would have paid a materially lower price.
Apparent vice: A defect discoverable by ordinary inspection. Generally does not support a redhibition action where the buyer had opportunity to inspect.
Latent vice: A hidden defect not discoverable by ordinary inspection. The seller's liability is greater; in some civil law systems, latent vice by a seller with knowledge supports additional damages.
Vice in title (vice du titre): A defect in ownership or the legal basis of a claimed right, distinct from a physical defect in the object itself.
Why It Matters in Research
The civil law defect doctrine is the primary research trap. Researchers working in Louisiana law, Quebec law, or civil law materials translated into English will encounter vice as a technical term of art. Louisiana Civil Code articles on redhibition use vice throughout; the doctrine has no direct common law equivalent, though it influenced warranty law. Older French and Spanish legal texts translated for American territorial law may use vice where modern common law materials would say "defect" or "breach of warranty" — the doctrinal implications differ.
For the prepositional use: when searching historical statutes, appointment records, or procedural documents, vice followed by a title (vice the appointed officer, vice-comes) is a Latin locution, not a reference to moral failing or civil law defect. The term vice-comes (literally "in place of the count") is the historical origin of viscount and, importantly, sheriff — a connection that surfaces in older English legal history research.
The moral-fault sense of vice generates its own research complexity in constitutional and regulatory history. The federal government's police power justifications for vice statutes (gambling, prostitution, obscenity) evolved significantly across the nineteenth and twentieth centuries. Researchers in this area should track the shift from morals-based regulation toward harm-based frameworks, as the doctrinal vocabulary shifts accordingly.
Historical Dictionary Support
The historical dictionaries are largely in agreement on the first two meanings and add useful texture. Black's (both editions) and Bouvier's treat the civil law defect doctrine as the primary substantive legal definition, with Bouvier's citing Pothier's Vente and the Louisiana Civil Code directly — the most useful primary source pointers in the shelf sources. Anderson's is most thorough on the Latin prepositional use, explicitly noting that vice as prefix signals a substitute empowered to act in case of "absence, incapacity, or death," and illustrating with vice-chancellor, vice-consul, and vice-president.
The historical dictionaries largely omit the regulatory/criminal sense of vice as moral conduct — presumably because that meaning was so well understood it required no legal definition. This is itself a research signal: the absence of a definition in Bouvier's or Black's for vice as "immoral conduct" does not mean the term lacked legal significance in that era. It simply reflects that the term was treated as self-evident. Researchers should not read that omission as confirmation that vice statutes lacked technical legal content.
Bouvier's reference to epilepsy in a slave and roaring and crib-biting in a horse as examples of redhibitory vices reflects the period's application of the doctrine to human beings as property — a usage that researchers in antebellum Louisiana legal history will encounter in primary sources and must handle with appropriate analytical care.
Jurisdictional Note
The civil law defect doctrine (redhibitory vice) is operative law in Louisiana and, in parallel form, in Quebec and other civil law jurisdictions. In common law states, the nearest equivalents are implied warranty of merchantability and related UCC provisions, but the doctrinal structure differs. Researchers should not assume that case law on civil law vice translates directly into common law warranty analysis.
