Definition
An unjust law; a law that is contrary to right or equity. The term denotes a legal enactment or rule that, by its nature or effect, falls outside the bounds of what is considered lawful in a just or legitimate sense. It is the conceptual opposite of a valid, rightful law — not merely a law that is unwise or inconvenient, but one regarded as fundamentally wrong or illegitimate.
Why It Matters in Research
This is a rare Anglo-Saxon term of art appearing almost exclusively in early medieval English legal sources. Researchers will encounter it chiefly in connection with the Leges Henrici Primi (Laws of Henry I), the early twelfth-century compilation that represents one of the few surviving attempts to systematize Anglo-Norman law in the generation after the Conquest. The term belongs to a stratum of legal vocabulary that predates the common law's systematic development and reflects the older Germanic legal tradition in which distinctions between law, custom, and moral legitimacy were intertwined.
The primary research trap here is anachronism. Modern legal systems generally draw a sharp line between positive law (what is enacted) and natural law or moral criticism of that law. Unlage collapses that distinction: in the pre-Scholastic Anglo-Saxon and early Norman legal world, a rule perceived as fundamentally unjust could be characterized as not truly law at all — a position closer to natural law theory than to modern legal positivism. Importing modern assumptions about the authority of enacted law will distort a researcher's reading of sources using this term.
Burrill cites Cowell's Interpreter as a secondary source for the term. John Cowell's Interpreter (1607) remains a useful bridge between medieval legal vocabulary and early modern understanding, and researchers working with Burrill's entry should consult Cowell directly for the fuller early modern gloss. The Leges Henrici Primi themselves are a notoriously difficult text — a private compilation, not a royal statute, with uncertain authority — which means that unlage as used there carries descriptive rather than strictly operative legal weight.
The term has no meaningful role in any post-medieval common law jurisdiction and will not appear in modern case law or statutory sources. Its relevance is confined to legal history, Anglo-Saxon studies, and the intellectual history of natural law concepts in early English law.
Historical Dictionary Support
Burrill's entry is terse but precise: he derives the term from the Anglo-Saxon components un (without) and lag (law), defines it as "an unjust law," and anchors it in two chapters of the Leges Henrici Primi (chapters 34 and 84) with a secondary citation to Cowell. This is characteristic of Burrill's treatment of archaic Anglo-Saxon terms — accurate derivation, sparse commentary, heavy reliance on earlier compilers.
No other dictionary on the Law Mind shelf carries this term, which is consistent with its extreme rarity in the legal literature. The term appears to have attracted no sustained jurisprudential development; it survives as a lexical artifact rather than as a working legal concept. Burrill's entry, though minimal, captures everything the term requires: origin, meaning, and source. There is no significant scholarly dispute about its definition, and no recorded divergence across historical sources.
Jurisdictional Note
Unlage is not a term in operative use in any modern common law jurisdiction. It belongs exclusively to the historical law of early medieval England and is relevant only in the context of Anglo-Saxon and early Anglo-Norman legal sources.
