Definition
In old English law, an accused person who sought to escape criminal liability by turning the accusation back upon his accuser — charging the accuser with the very same offense. The antithetarius did not simply deny the charge; he affirmatively recriminated, asserting that the accuser was himself guilty of the act alleged.
Common Confusion
Antithetarius is frequently grouped with, or vaguely distinguished from, the approver (approbator) — a person who confessed to a crime and then accused confederates in exchange for pardon. The distinction is precise and matters for reading historical records correctly:
- The antithetarius charges his accuser with the same crime alleged against himself.
- The approver does not charge the accuser at all; he charges others — typically alleged co-conspirators or confederates.
The two figures operated within related but distinct procedural frameworks. An approver's testimony was a tool of the prosecution; the antithetarius's recrimination was a tool of the defense. Collapsing the two obscures which procedural posture a historical record is describing.
Why It Matters in Research
This is a term of purely historical significance, extinct in modern legal usage. Researchers encountering it will find it only in medieval English legal records, early common law treatises, and Latin legal glossaries. It surfaces in discussions of ancient criminal procedure, particularly in contexts predating formal adversarial trial structures, when the mechanics of accusation, proof, and counter-accusation operated very differently from modern practice.
The key navigational point: antithetarius is procedurally specific. It describes a recognized defensive posture within a system where the accuser bore personal risk if the accusation failed — a feature of older English and continental law that has no direct modern counterpart. Researchers tracing the historical roots of recrimination doctrines, the right of confrontation, or the development of prosecutorial immunity will find this term a useful marker pointing toward that earlier procedural landscape.
Do not conflate this term with its nearest neighbor, the approver (see RELATED TERMS). The historical sources are unanimous on the distinction, and confusing them will misread the procedural posture of any case or record in which either term appears.
Historical Dictionary Support
The four source dictionaries present a notably consistent account, all tracing back to the same authority chain: Jacob's Law Dictionary and, behind it, Cowell's Interpreter. Burrill adds Whishaw and supplies the Greek root (antithesis, opposition), which is useful for understanding the Latin coinage but not dispositive of legal meaning.
All sources agree on the core definition: the antithetarius recriminates against the accuser specifically, not against third parties. All sources also agree on the distinction from the approver. Where Burrill diverges slightly from Black's and Bouvier's is in framing: Burrill emphasizes the procedural act of "recriminating" and characterizes it as charging the accuser with "the same fact," while Black's and Bouvier's speak more generally of "retorting the charge." Burrill's formulation is the more precise — the recrimination was directed at the identical offense, not merely a counter-allegation of some unrelated wrongdoing.
None of the historical sources provide sufficient procedural context to reconstruct exactly how this defense operated in practice — what evidentiary standard applied, what court administered it, or what outcome followed a successful or failed antithetarian defense. Researchers needing that context will need to go beyond the dictionary shelf to Cowell's Interpreter directly, or to primary medieval legal sources.
Jurisdictional Note
This term belongs to old English law and has no recognized equivalent in American, Scottish, or civilian legal systems. It does not appear in modern common law jurisdiction statutes or case law. Its relevance is limited to historical legal research in the English medieval and early modern context.
