Definition
To denounce, in legal usage, means to declare formally that an act constitutes a crime and to prescribe a punishment for it. When a legislature or legal authority "denounces" conduct, it identifies that conduct as criminal and attaches a legal consequence to it. The term operates in the direction of lawmaking — it is the act by which law defines and condemns prohibited behavior.
Secondarily, and in a looser, non-technical sense, "denounce" is used as a near-synonym for "accuse" or "inform against" — that is, to report a person to authorities as having committed a wrongdoing. Black's Law Dictionary (2nd Ed.) flags this usage explicitly as popular rather than technical.

Common Language
Modern common usage (Wiktionary): To pronounce someone or something as wrong, evil, or criminal; to make a formal public accusation or condemnation; to give formal notice of the termination of a treaty or agreement.
Historical common usage (Webster's 1913): To pronounce a threat against; to threaten; to proclaim in a threatening manner; to point out as deserving of reprehension or punishment; to accuse publicly; to inform against.
The gap here is meaningful. In ordinary language, denouncing is something one person does to another — an accusation, a public condemnation, or a moral indictment. In legal usage, the primary technical meaning runs in the opposite direction: it is the law itself that denounces conduct, not an individual denouncing another person. A researcher encountering "denounced by statute" in a legal text should read it as the statute having declared and penalized the conduct — not as an accusation by a private party.

Common Confusion
The dual usage flagged by Black's creates a real interpretive trap. When a historical legal text says an act is "denounced," the reader must determine from context whether the writer means (1) that the law has formally declared the act criminal and attached a punishment, or (2) that some person has accused or reported another. The first is the technically correct legal meaning; the second is the loose, popular borrowing from common speech. In statutory and judicial texts, the technical meaning almost always controls. In police reports, proceedings, or civil-law influenced jurisdictions (including Louisiana), the popular meaning appears more frequently.

Why It Matters in Research
This term is a minor trap for researchers working in older American case law, particularly in Louisiana and other civil-law influenced jurisdictions where the term surfaces more often than in common-law courts. The Louisiana case cited in Black's — *State v. De Hart* — arises from that civil-law tradition, and the usage there tracks the Roman and French legal meaning of formal legal condemnation by statute rather than informal accusation.
Researchers reading 19th-century criminal law materials should watch for this term as a descriptor of legislative action: a statute "denouncing" a penalty means the statute has made the act criminal and specified the consequence. This usage is substantially archaic in contemporary American legal writing, where "prohibit," "criminalize," or "prescribe" have displaced it. If you encounter "denounce" in modern legal texts, the common-language meaning (public condemnation) or the international-law meaning (formal notice of treaty withdrawal) is far more likely intended.
In comparative and international law materials, "denunciation" carries a third distinct meaning — the formal withdrawal of a state from a treaty — which is entirely separate from either the criminal-law or accusatory senses. This usage is alive and current. Researchers moving across these bodies of law should not carry a single meaning of the term from one context to another.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) provides the only source in this entry's corpus, and it handles the term with appropriate precision: the technical meaning (legislative declaration of crime and punishment) is given primacy, and the popular meaning (accusation or informing against) is explicitly labeled non-technical. The citation to *State v. De Hart* anchors the technical meaning in actual judicial usage rather than treating it as merely theoretical.
What historical dictionaries of this era do not capture is the international-law usage of "denunciation" as treaty withdrawal — a meaning that was developing in diplomatic practice but would not be prominent in a general American law dictionary of this period. Modern researchers should not expect historical legal dictionaries to illuminate that usage.

Jurisdictional Note
The technical legal meaning — law denouncing conduct as criminal — appears most often in Louisiana case law and in jurisdictions with civil-law influences, reflecting the term's stronger presence in French and Spanish legal vocabulary. In common-law jurisdictions, the same concept is expressed through "prohibited by statute," "made criminal," or "penalized." The international-law sense (denunciation of a treaty) is jurisdiction-neutral and governed by principles of international law, not domestic criminal law.
