Definition
A Latin phrase meaning "of not allowing talliage" (or "of not granting talliage"). The term names a writ, and more broadly refers to the English statutes of 25 Edward I and 34 Edward I, which restricted the Crown's power to impose talliage — a form of tax or levy — without consent. In medieval English law, talliage was a compulsory exaction that the king could demand from royal towns, boroughs, and demesne lands. The statutes designated by this phrase were constitutional landmarks limiting that prerogative, placing the power to tax more firmly in the hands of Parliament and requiring consent before such levies could be granted or imposed.
The phrase itself functions in legal literature as a shorthand label for this body of restriction, not as the name of a single document but as a descriptor for the legislative and prerogative constraint it embodied.

Common Confusion
DETALLAGIO NON CONCEDENDO is sometimes loosely grouped with Magna Carta and the Confirmatio Cartarum as part of the same cluster of medieval constitutional documents restraining royal power. While they share that general character, they address distinct mechanisms: Magna Carta operates broadly on royal arbitrary action, the Confirmatio Cartarum (1297) confirmed the charters, and the talliage statutes specifically addressed the taxing power over towns and demesne. Researchers should not treat these as interchangeable citations when tracing the history of parliamentary consent to taxation.
The term should also not be confused with TALLAGE itself (the underlying tax being restricted) or with the writ de tallagio non concedendo, which some sources treat as a distinct procedural instrument rather than the statute itself. Historical sources are not always consistent on this boundary.

Why It Matters in Research
This term appears primarily in historical and constitutional law research concerning the development of parliamentary taxation authority in medieval England. Researchers will encounter it most often in secondary treatments of English legal history rather than in operative legal documents, and almost never in modern statutory or case materials.
Several research traps apply. First, the spelling varies across sources — detallagio, de tallagio, de tallagio non concedendo — and older indices may catalogue it inconsistently. Searching the Law Mind corpus under any single spelling may miss relevant material. Second, the status of the underlying instrument has been disputed: whether the talliage restrictions of Edward I's reign constituted genuine statutes with binding force, or were instead administrative declarations of uncertain authority, was a live question among constitutional historians. Coke treated them as statutes of high constitutional dignity; later historians have been more skeptical. Researchers citing this term to establish principles of consent to taxation should be aware that its authority as a formal source of law is contested.
Third, the connection to talliage is essential context. Without understanding what talliage was — a levy distinct from aids, scutage, and subsidies, applicable specifically to royal demesne and towns — the significance of the restriction is lost. The Law Mind Encyclopedia entry on Taxation will provide that background.

Historical Dictionary Support
Bouvier's Law Dictionary identifies the term as a Latin phrase meaning "of not allowing talliage" and ties it directly to the statutes of 25 and 34 Edward I, citing Coke's Second Institutes at page 532 and Reeve's History of English Law at volume 2, page 104. Bouvier's treatment is brief, functioning as a cross-reference point rather than a full exposition; the substance is deferred to the entry on TALLIAGE.
Coke's authority underlies Bouvier's framing. Coke in the Second Institutes elevated these statutes as fundamental constitutional sources, consistent with his broader project of reading medieval English law as a continuous tradition of liberty against royal overreach. Reeve, writing in a more strictly historical mode, provides the narrative context Coke does not.
What historical dictionaries largely omit is the modern scholarly debate over whether these instruments were ever formally enacted as statutes in the technical sense, or whether their constitutional prestige rested more on later interpretation than on original legal force. Researchers working in constitutional history should supplement dictionary sources with the historical literature directly.

Jurisdictional Note
This term has no application in modern American or Commonwealth statutory law. Its relevance is confined to English legal history, specifically the medieval and early modern periods, and to constitutional scholarship examining the origins of parliamentary control over taxation.
