Definition
An allegation of diminution is a formal assertion made in appellate proceedings that the record transmitted from the lower court to the appellate court is incomplete, inaccurate, or defective — that something has been left out or reduced from the full record as it existed below. The party making the allegation contends that the record sent up does not fully or faithfully represent the proceedings in the court of first instance, and seeks to have the record corrected or supplemented before the appellate court proceeds to judgment.
The procedural mechanism associated with this allegation was the writ of certiorari in its original, non-constitutional sense: a writ directed to the lower court commanding it to certify and send up the missing or corrected portion of the record. In this historical context, certiorari functioned not as a means of discretionary appellate review (its modern American constitutional role) but as a purely ministerial instrument for completing a deficient record.

Common Confusion
Modern researchers frequently encounter "certiorari" in historical sources and assume it refers to discretionary review of a lower court's decision on the merits — the familiar U.S. Supreme Court usage. When historical sources use certiorari in connection with an allegation of diminution, the term carries an entirely different function: compelling the lower tribunal to supply what is missing from the record, with no review of the merits implied. Conflating these two uses distorts the procedural posture of historical cases. See also the distinction between writ of error and certiorari in pre-nineteenth-century appellate practice.

Why It Matters in Research
This term is a navigational marker for a now-obsolete procedural mechanism that operated at the intersection of appellate record practice and prerogative writ procedure. Researchers will encounter it almost exclusively in English common law materials and early American practice, particularly before the consolidation of appellate procedure under unified codes in the nineteenth century.
Several traps await researchers working in historical sources:
First, the term does not appear prominently in many legal dictionaries because it functioned as a term of art within a specific procedural context rather than as a standalone substantive concept. Burrill directs readers to the entry for DIMINUTION rather than defining the allegation independently — meaning a researcher who stops at the entry itself will miss the substance entirely and must follow the cross-reference.
Second, the underlying concept of diminution — a deficiency or omission in the record — connects directly to the historical mechanics of the writ of error. Under writ-of-error practice, the entire record of the inferior court was theoretically brought before the reviewing court. Any gap in that record was not a minor procedural inconvenience but a potentially dispositive problem, because the appellate court's jurisdiction and authority to act depended on the completeness of what was certified to it. An allegation of diminution was the formal vehicle for raising that problem.
Third, when researching early American appellate cases, the allegation of diminution may appear in the procedural history without being labeled as such. Researchers should watch for language about a defective, incomplete, or uncertified record alongside references to a certiorari issued to the court below — that cluster of facts often signals that an allegation of diminution was in play.
Fourth, the concept has a faint modern echo in rules governing the correction or supplementation of the appellate record, found in most contemporary rules of appellate procedure. While the formal allegation of diminution and its associated writ are gone, the underlying problem — an incomplete or inaccurate record on appeal — persists, handled now by motion practice rather than prerogative writ.

Historical Dictionary Support
Burrill's Law Dictionary does not provide a substantive definition at this entry, instead directing the reader to DIMINUTION — a cross-reference structure that itself tells researchers something important: the allegation was understood as derivative of the underlying concept, not as an independent procedural institution warranting separate treatment.
The historical dictionaries that address diminution in the appellate context (including Bouvier and Tomlin) consistently tie it to the idea of a record that has been shortened, omitted, or imperfectly transmitted — the Latin root suggesting a lessening or reduction. The allegation of diminution was thus the formal accusation that something had been taken away from the record, whether through clerical error, omission, or the lower court's failure to certify the full proceedings.
What the historical dictionaries collectively underemphasize is the practical significance of this mechanism in shaping appellate outcomes. A successful allegation could delay proceedings, force supplementation of the record, and in some cases reveal procedural errors below that would otherwise have remained hidden in an incomplete transcript. Historical sources treat it as a procedural formality; in practice it could be a meaningful litigation tool.

Jurisdictional Note
The allegation of diminution and its associated certiorari remedy were features of English common law appellate practice adopted into early American federal and state courts. As states reformed their appellate procedures through the nineteenth and twentieth centuries, the formal mechanism disappeared. Researchers working in English ecclesiastical, chancery, or King's Bench records will find the term more frequently than in American sources after approximately 1850.
