Definition
A civil law remedy — specifically a form of interdict or injunction — available to a party whose rights are threatened by a neighbor or adversary about to erect or commence a "new work" on land or property. The action operated as a formal prohibition: by invoking it, the complaining party could compel the would-be builder to halt construction pending legal resolution of whether the proposed work would unlawfully injure the plaintiff's rights. The phrase translates roughly as "concerning the prohibition of a new work." The underlying mechanism, the nunciatio, was a solemn protest or declaration made before witnesses at the site of the proposed work, giving legal force to the objection before a magistrate could issue formal relief. The remedy was not a claim for damages already suffered but a preventive measure aimed at stopping harm before it occurred.
Common Confusion
The term is sometimes loosely equated with modern injunctive relief in property disputes, but the analogy is imperfect. The nunciatio was a specific civil law procedural device with its own formal requirements — including the on-site protest — that has no direct procedural equivalent in common law equity practice. Researchers should also distinguish this remedy from the broader category of Roman interdicts generally; de novi operis nunciatione addressed prospective construction specifically, whereas other interdicts governed possession, access, or completed interference.
Why It Matters in Research
This term surfaces almost exclusively in civil law contexts and in American legal scholarship that engages Roman law foundations, particularly in Louisiana, Quebec, and comparative property law materials. Researchers working in Louisiana property law should be alert: Louisiana's civil law tradition preserved functional analogues to the nunciatio in its codified law of property and servitudes, so historical Louisiana cases and treatises may reference this concept directly or through closely related French and Spanish civil law terminology.
The term also appears in treatises on the law of nuisance, particularly older works tracing the historical roots of preventive relief against construction that interferes with easements, servitudes, or rights of light and prospect. When reading such treatises, researchers must recognize that the Roman mechanism was considerably more formalized and narrower in scope than modern nuisance injunctions.
In corpus searching, the Latin phrase and its variants (including nunciatio operis novi) appear inconsistently across sources. Some authorities index the concept under NUNCIATIO, others under OPERIS NOVI, and still others under the interdict rubric. Burrill's direct cross-reference to "Nuntiatio" is a useful navigational signal: researchers who locate this term should immediately pursue the related entry rather than treating this entry as self-contained.
The Digest citation in Burrill (Dig. 39.1, not 30.1 as printed — likely a typographical error in the original) is the classical source. Researchers relying on Burrill should verify the Digest reference independently before citing it.
Historical Dictionary Support
Black's (both editions) and Burrill's agree on the essential character of the remedy: an interdict or injunction against prospective construction injurious to the plaintiff's rights. The definitions are consistent but thin. Neither edition explains the procedural mechanism of the nunciatio itself — the on-site protest, the role of witnesses, or the magistrate's subsequent role — leaving researchers without the operational context needed to understand how the remedy functioned in practice. Burrill adds the useful cross-reference to the Digest and to his own "Nuntiatio" entry, making it the more research-navigable of the three sources despite its brevity.
None of the three dictionary sources distinguishes between the nunciatio as a self-help protest and the formal judicial interdict that might follow, a distinction that matters considerably in comparative law scholarship. For fuller treatment, researchers should consult primary civilian sources and comparative property law treatises rather than relying on these dictionary entries alone.
Jurisdictional Note
This remedy is a product of Roman civil law with no direct common law counterpart. It remains relevant primarily in Louisiana and in comparative or historical legal scholarship. In mixed civil law jurisdictions, functionally similar preventive remedies in property law may trace their doctrinal lineage to this concept even when the Latin terminology is absent.
