Definition
De tallagio non concedendo (Latin: "of not allowing talliage") is the name given to one or more English statutory instruments from the reign of Edward I — most commonly associated with the statutes of 25 Edward I and 34 Edward I — that restricted the Crown's power to impose or grant talliage without the consent of the realm. Talliage (also spelled tallage) was a form of arbitrary royal taxation levied on towns, boroughs, and royal demesne lands without parliamentary or representative approval. These instruments stand as early constitutional landmarks asserting that the king could not tax his subjects without consent — a principle later absorbed into the broader constitutional settlement that includes Magna Carta and, much later, the Bill of Rights 1689.
The precise legal status of De Tallagio Non Concedendo has been debated for centuries. Some scholars have treated it as a confirmatory statute; others have argued it was never formally enacted but circulated as a draft or petition. Edward Coke cited it in 2 Institutes as genuine statutory authority, which gave it outsized influence in 17th-century constitutional arguments even if its authenticity as a formally enacted statute remained contested.
Common Confusion
De Tallagio Non Concedendo is frequently conflated with the Confirmatio Cartarum (Confirmation of the Charters, 25 Edward I, 1297), which confirmed Magna Carta and the Charter of the Forest, and which also contained provisions limiting irregular taxation. The two documents emerged from the same constitutional crisis of Edward I's reign and are sometimes cited interchangeably in older sources. They are distinct instruments: Confirmatio Cartarum has unambiguous statutory status and survives in the Parliament Rolls; De Tallagio Non Concedendo's formal enactment is disputed. Researchers should not treat a citation to one as authority for the other.
Why It Matters in Research
Several research traps surround this term.
First, authenticity is genuinely contested. When you encounter De Tallagio Non Concedendo cited as statutory authority in 17th-century sources — including Coke's Institutes and parliamentary debates surrounding the Petition of Right 1628 — understand that those citations reflect the political use of the document as much as its legal pedigree. Parliamentarians deployed it against Stuart prerogative claims. The document's rhetorical force in that period was enormous; its status as enacted law was, even then, uncertain.
Second, Coke's 2 Institutes citation (2 Inst. 582) is the primary transmission path through which this term enters later legal dictionaries, including Black's. Researchers working backward from Black's 2nd Edition to the underlying source will find themselves at Coke, not at a clean statutory text. This matters when evaluating the weight of the authority in any given historical argument.
Third, for constitutional history researchers, the term is a node in a network connecting Magna Carta, Confirmatio Cartarum, the Petition of Right, and early parliamentary sovereignty doctrine. Sources treating English constitutional development from the 13th through 17th centuries will use these instruments as a cluster. Understanding De Tallagio Non Concedendo's place in that cluster — and its contested status within it — prevents misreading of sources that treat it as settled law.
Fourth, the term appears rarely in American legal materials, but when it does appear, it is almost always in the context of no-taxation-without-representation arguments, sometimes reaching back through Coke to this document. Colonial-era pamphlets and early American constitutional debates occasionally invoked it alongside Magna Carta. Researchers in early American legal history should recognize it in that context.
Historical Dictionary Support
Black's Law Dictionary (2nd Edition) gives a spare entry: the Latin gloss "of not allowing talliage," identifies the relevant statutes as 25 and 34 Edward I, and cites Coke's 2 Institutes at page 582 and Reeve's History of English Law at volume 2, page 104. The entry reflects the document's reception in the common law tradition more than it resolves the authenticity question — Black's treats it as established authority without flagging the historiographical controversy.
What the historical dictionary entry misses is significant: it does not note that the document's enactment has been disputed since at least the 19th century, nor does it distinguish between De Tallagio Non Concedendo and Confirmatio Cartarum. Reeve's citation (History of the English Law) would provide a more contextual discussion than Black's condensed entry suggests. Researchers relying solely on Black's 2nd Edition for this term will receive accurate but incomplete information that may encourage overcitation of a document whose legal status warrants more caution than Coke and subsequent dictionaries have generally applied.
Jurisdictional Note
This is an instrument of English law with no direct American statutory counterpart. Its significance in U.S. legal and constitutional research is historical and rhetorical — it appears in arguments about the origins of the no-taxation-without-consent principle, not as operative law.
