Definition
An act of formal accusation or public notification. The term carries distinct meanings depending on legal context:
1. Civil law. The act by which a private individual formally informs a public officer — typically a prosecutor or magistrate — that a crime has been committed, triggering that officer's duty to investigate or prosecute. The informer does not necessarily become a party to proceedings; the denunciation is a prompting act, not a pleading.
2. Scots law. A formal declaration by which a person who has failed to comply with letters of horning is pronounced a rebel against the Crown. The denunciation marked entry into a state of civil outlawry and carried serious legal consequences under Scots procedure.
3. International law. The formal notification by a state party that it is withdrawing from or terminating its obligations under a treaty. Denunciation in this sense is an act of sovereign will, often governed by the treaty's own terms regarding notice periods and procedure.
4. Old English and ecclesiastical usage. A summons, public notice, or solemn warning issued by an authority — including the public proclamation of banns before marriage. This usage is largely obsolete in modern practice.

Common Language
Modern common usage (Wiktionary): The act of denouncing; a public accusation or open declaration of fault; a threat or public menace; the announcement of termination of a treaty.
Historical common usage (Webster's 1913): Proclamation or announcement; public menace or accusation; arraignment; a threat of evil; also, the publishing of banns before marriage.
The common usage captures the accusatory and declaratory flavor of the word well enough, but misses the civil-law precision of the term as a procedural act with legal consequences. In ordinary speech, denunciation suggests moral condemnation or rhetorical attack. In civil law, it is a specific triggering mechanism in criminal procedure — the act that sets prosecution in motion — and carries no necessary implication of public spectacle or moral censure.

Common Confusion
Denunciation is sometimes conflated with accusation and information, but the three are not synonymous. An accusation (in common law tradition) typically names a specific charge against a specific person. An information is a formal charging instrument filed by a prosecutor. A denunciation, in the civil law sense, is a step earlier in the process: it is the act of bringing a crime to official attention, leaving the decision to charge with the public officer. Rapalje & Lawrence flag this directly, treating denunciation as equivalent to accusation while noting its distinct procedural role. The Scots use of the term to mean a declaration of rebel status is entirely separate from either the civil law or common law senses and should not be read interchangeably with them.

Why It Matters in Research
Researchers encounter this term across at least three distinct legal traditions — civil law, Scots law, and international law — and the meanings do not overlap. Misreading context is the primary hazard.
In historical American sources, denunciation in the civil-law sense appears most often in treatises engaging Roman or French law foundations, including early Louisiana materials. The term was not a working part of common law criminal procedure in most American jurisdictions, so its appearance in an American source often signals civil-law influence or scholarly comparison rather than domestic practice.
The Scots sense — denunciation as a step in horning procedure — will appear in Scottish legal records and in comparative treatments of outlawry. It has no counterpart in English common law practice and should not be imported into readings of English or American materials.
The international law sense — treaty denunciation — is fully alive in modern usage and creates its own research trap: the word sounds hostile or accusatory in ordinary English, but in treaty law it is a neutral, procedurally governed act that may be entirely amicable. Modern international law instruments and commentary use the term in this technical sense without any implication of wrongdoing.
The ecclesiastical usage (public denunciation of banns) appears in older church law materials and early marriage law sources. It is obsolete in practice but surfaces in historical records and should not be confused with any of the criminal or procedural senses.

Historical Dictionary Support
Black's (1st ed.), Black's (2nd ed.), and Bouvier's are in close agreement on the civil law definition, each framing denunciation as the act by which an individual informs a competent public officer that a crime has been committed. Bouvier cites Pothier and Ayliffe, anchoring the definition firmly in the Roman and canonical law tradition. Neither Black's edition goes much beyond the civil law and Scots senses.
Rapalje & Lawrence treat denunciation more briefly, glossing it as equivalent to accusation and noting the old English usage as a summons or public notice — a useful reminder that the term had procedural application beyond the civil law context.
None of the historical dictionaries address the international law sense of treaty denunciation, which had not yet become a prominent feature of legal vocabulary when these works were compiled. Researchers working in modern international law should not expect coverage in these sources and should turn to later specialized materials.
The Black's (1st ed.) entry in the source material contains an apparent editorial artifact — text about denizens and Lord Denman's Act — which belongs to adjacent entries and should be disregarded as a transcription overlap.

Jurisdictional Note
In the United States, denunciation in the civil-law procedural sense is most relevant to Louisiana, which inherited civil law criminal procedure traditions from French and Spanish sources. In international law, treaty denunciation is governed by each treaty's own terms and, in their absence, by customary international law principles codified in the Vienna Convention on the Law of Treaties.
