Definition
A Latin term for an accuser — specifically, a person who formally charges another with a criminal offense. In Roman law and in early English legal practice informed by that tradition, the accusator was the individual who initiated a criminal prosecution by presenting a charge before a tribunal. The role was not merely that of a complainant or witness but carried formal procedural standing and responsibility: the accusator initiated the proceeding and was bound by its outcome.
The term appears in legal Latin maxims and early common law sources but is not a term of art in modern Anglo-American law. Its primary relevance today is in reading historical legal texts, Roman law sources, and ecclesiastical law materials.
Why It Matters in Research
Researchers encountering accusator in historical sources should recognize it as a term of Roman law origin that carried procedural weight distinct from the modern concept of a complaining witness or prosecutor. In Roman criminal procedure, the accusatorial system placed the burden of initiation on the private accusator, who risked punishment under the lex talionis or charges of calumnia (malicious accusation) if the prosecution failed. This is materially different from the modern public prosecution model, and conflating the two distorts the meaning of the source.
The maxim preserved in Burrill — Accusator post rationabile tempus non est audiendus, nisi se bene de omissione excusaverit — is a functional limitation on stale accusations and is worth noting for researchers working on the history of statutes of limitations, laches, or the diligence requirements in criminal prosecutions. The citation to Moor 817 refers to Moore's Reports, a collection of English cases from the late sixteenth and early seventeenth centuries.
When reading ecclesiastical court records or canon law texts, accusator may appear alongside terms like delator (an informer) and denunciator (one who denounces before a church tribunal) — roles that Roman and canon law carefully distinguished but that English legal writers sometimes blurred. Misreading these distinctions affects interpretation of how charges were initiated, who bore procedural risk, and what evidentiary standards applied.
Historical Dictionary Support
Burrill's Law Dictionary gives accusator its straightforward Latin gloss — "an accuser" — and immediately supplies the maxim on timeliness, signaling that the term's practical legal content in English sources is primarily maxim-driven rather than doctrinal. Burrill does not develop the Roman law procedural context, which is the fuller setting researchers need.
Historical dictionaries generally treat accusator as a term to be translated rather than analyzed, reflecting the fact that by the time major English law dictionaries were compiled, the accusatorial role as a formal legal category had been absorbed into or displaced by the office of public prosecutor and the grand jury system. The term survives in English legal literature largely as a Latinism in maxims and in scholarly treatments of Roman and canon law rather than as an operative term in common law pleading or practice.
What historical sources miss: none of the standard English law dictionaries of the eighteenth or nineteenth century give substantive attention to the procedural liability of the accusator — the risk of counter-prosecution for false accusation — which is essential to understanding why the role functioned as a check on frivolous charges in Roman law. Researchers working on comparative criminal procedure or the history of malicious prosecution should look beyond the dictionary shelf to Roman law treatises for this dimension.
Jurisdictional Note
Accusator is not a term in operative use in any modern Anglo-American jurisdiction. It appears in Louisiana legal materials more frequently than in other American jurisdictions due to that state's civil law heritage, but even there it functions as a historical or scholarly term rather than a live procedural category.
