Definition
A Latin term from old common law practice meaning "denied" or "it was denied." Dedictum appears in procedural contexts to record that a party or court has formally denied or refused a matter. The term derives from the Latin dedicere, meaning to deny or to unsay.
In medieval English legal practice, dedictum functions as the past participial form indicating a formal denial on the record. It appears in two closely related procedural postures:
1. Denial by the court: The formula quod non fuit dedictum per curiam — "which was not denied by the court" — records that the court raised no objection to or denial of a matter before it.
2. Denial by a party: The formula aut dedicit aut cognoscit — "he either denies or acknowledges" — describes the binary choice presented to a party required to respond to a claim. The party must either formally deny the allegation or admit it. A related construction, petens hoc dedicere non possit ("the demandant cannot deny this"), signals that the burden of denial was unavailable to the claiming party in certain procedural postures.
Common Confusion
Dedictum should not be confused with the broader Latin term negatio (general negation or denial) or with the pleading term non culpabilis (not guilty). Dedictum is a term of art specific to the formal record notation of denial in old English practice, not a substantive plea or defense in the modern sense. Researchers encountering it in Year Books or early reporters should treat it as a procedural marker, not a term carrying independent doctrinal weight.
Why It Matters in Research
Researchers working in pre-modern English legal sources — particularly Bracton, Fleta, the Year Books, and early Dyer reports — will encounter dedictum in formulaic phrases embedded in procedural narratives. The term is not independently indexed in most modern finding tools, which means it surfaces only through close reading of original text rather than keyword search.
Several practical cautions apply:
The term exists almost exclusively in Latin pleading records and treatises predating the gradual anglicization of English legal procedure. By the seventeenth century, such Latin formula terms were being displaced by English procedural language, so dedictum will appear heavily in medieval and early modern sources and rarely if ever in post-Restoration materials.
The phrase aut dedicit aut cognoscit reflects a foundational feature of early common law pleading: the requirement that a party take a clear position — denial or acknowledgment — rather than equivocate. Understanding this binary structure helps researchers interpret why certain early pleading records appear to lack what modern procedure would call affirmative defenses or conditional responses.
When Burrill cites Dyer 14 for quod non fuit dedictum per curiam, the reference is to a court notation that the bench itself did not formally contradict the matter — a form of procedural acquiescence. Researchers should not read this as affirmative endorsement by the court, only the absence of recorded denial.
The appearance of dedictum alongside Bracton (fol. 214) and Fleta (lib. 3, c. 14, § 5) places the term firmly within the thirteenth-century systematization of English common law. Bracton and Fleta are companion treatises, and finding the same formula in both suggests it was a term of recognized procedural art, not an isolated usage.
Historical Dictionary Support
Burrill's Law Dictionary is the primary dictionary source for this term, and its entry is the most substantive historical record readily available in this corpus. Burrill correctly identifies the Latin derivation (dedicere, to deny), provides the two core formulaic uses, and supplies the relevant citations to Dyer and Bracton. The entry is compact but accurate.
What Burrill does not provide — and what no historical law dictionary in common circulation addresses fully — is any synthesis of how dedictum fits within the larger structure of early common law pleading theory. The term is treated as a vocabulary item rather than a window into the underlying procedural logic of denial and acknowledgment. Researchers wanting that context should turn directly to Bracton's De Legibus et Consuetudinibus Angliae and Fleta rather than relying on dictionary sources alone.
No entry for dedictum appears in Tomlin's Law Dictionary, Jacob's Law Dictionary, or Black's Law Dictionary in its modern editions, reflecting the term's obsolescence outside historical research contexts.
Jurisdictional Note
Dedictum is exclusively a term of old English common law practice. It has no recognized use in American, Scottish, or civilian legal systems. Researchers in early American colonial records may encounter it in materials directly transplanted from English practice, but it does not appear in any American procedural codification.
