Definition
A writ directing the transmission of the record and process of a cause from an inferior court to a superior court for review. Mittendis is a species of writ of error — a formal mechanism by which an appellate or superior tribunal commanded the lower court to send up the materials of a decided case so that the superior court could examine the proceedings for legal error.
The writ is Latin in character and belongs to the classical common law system of original writs. Its function was procedural rather than substantive: it did not itself correct any error but ensured the superior court had the record before it on which correction could be made.
Common Confusion
MITTENDIS vs. CERTIORARI: Both writs operate to bring a case's record before a superior court, and in modern practice certiorari has absorbed the functional territory once occupied by mittendis and related writs of error. The distinction matters in historical research: mittendis was specifically associated with the error-review process and the transmission of record and process together, while certiorari historically operated more broadly to supervise inferior tribunals, including in circumstances where no formal writ of error lay. Researchers encountering either term in pre-nineteenth-century materials should not assume functional equivalence.
MITTENDIS vs. DIMINUTION OF RECORD: Where mittendis commanded transmission of the full record from the outset, a writ of diminution of record was used when the record sent up was alleged to be incomplete. These are sequential rather than competing writs: mittendis initiates the transmission; diminution of record corrects it.
Why It Matters in Research
Mittendis appears almost exclusively in pre-modern English common law sources — primarily early modern treatise literature, register of writs materials, and forms books. Researchers will not encounter it in living practice. Its significance in the Law Mind corpus is therefore historical and taxonomic: understanding where mittendis sits within the writ of error family helps map the procedural architecture of classical appellate review.
The key navigational point is that mittendis belonged to a cluster of ancillary writs that supported the writ of error process. The Registrum Omnium Brevium (Register of Original Writs), to which Black's cites, is the primary locus classicus for its formal existence. Researchers consulting that source or related Chancery register materials will find mittendis listed among the procedural writs tied to error review rather than among the original writs initiating actions.
Because the writ of error system was abolished or superseded in both English and American practice during the nineteenth century — replaced progressively by statutory appeal procedures and, in American federal courts, by the modern certiorari jurisdiction — mittendis has no analogue in current procedural codes. Any appearance of the term in materials post-dating that transition is either historical quotation or scholarly commentary, not operative law.
Jurisdictional variation is not a meaningful issue here: the writ never had significant independent American development and is not a common law survival in any U.S. jurisdiction.
Historical Dictionary Support
Black's Law Dictionary provides the only entry among the standard historical law dictionaries for mittendis. The definition is spare — "writ to send the record and process of a cause to a superior court; a species of writ of error" — and cites Reg. Orig. 209, a reference to the Registrum Originale (or Registrum Omnium Brevium), the authoritative register of original writs in English common law practice. The citation is to a recognized historical source and provides the only primary anchor for the writ's formal existence.
No substantive elaboration appears in the standard dictionary sources. Blackstone, Coke, and the major English procedural treatises treat the writ of error family collectively rather than isolating mittendis as a term of art. This means the definition Black's provides is essentially the full extent of received dictionary authority, and researchers seeking deeper treatment must go to the register materials directly or to procedural history scholarship on the medieval and early modern writ system.
The sparseness of the historical record on mittendis as a distinct term — as opposed to the writ of error process generally — suggests it was a technical form rather than a term in wide legal discourse. It named a specific instrument in the register without generating substantial doctrinal commentary of its own.
