Definition
De rubra spatha is a Latin phrase meaning, literally, "of the red sword." In medieval English legal usage, it referred to a right or privilege associated with the bearing of a drawn or unsheathed sword — specifically in the context of jurisdictional authority, high justice, or the symbolic power of lords to exercise capital punishment or high criminal jurisdiction within their demesne. The phrase belongs to the vocabulary of feudal franchise law, describing one of the more extreme prerogatives that a lord might hold by grant or prescription: the power to enforce justice at the point of the sword, up to and including the taking of life.
The term is closely allied with related franchise phrases denoting the full spectrum of high and low justice, and appears in Latin records alongside companion rights such as infangthief and outfangthief — rights to try and execute thieves caught within or without a lord's territory.

Why It Matters in Research
Researchers will encounter this term almost exclusively in Latin administrative records, plea rolls, and franchise surveys from the medieval English period — Domesday Book materials, eyre rolls, and inquiries into liberties. It does not survive into modern common law as an operative legal concept; its relevance today is entirely historical and interpretive.
The primary trap for the corpus researcher is the variant spelling problem. Burrill's entry catalogs the term under the anglicized and corrupted forms: Rospear, Rouspee, Rooper, and Roper. These phonetic renderings reflect how medieval and early modern clerks transliterated or anglicized the Latin phrase when recording franchise claims in English-language documents or when witnesses and tenants described rights they held by long custom but could no longer articulate in Latin. A researcher searching only for "de rubra spatha" in Latin records will miss a substantial body of material recorded under these anglicized variants, and vice versa.
The corruption from Latin to vernacular form is significant: "rubra spatha" (red sword) becomes "rospear" or "rooper," forms that are phonetically distant enough to obscure the connection entirely unless a researcher is alert to the translation chain. Burrill's signal here is valuable — it confirms the direct equivalence between the Latin phrase and these English-language corruptions.
Jurisdictional franchise research in medieval English sources requires awareness that the same right may appear in any of the following registers: Latin in formal royal writs and plea rolls, Anglo-Norman in intermediate administrative documents, and anglicized vernacular forms in local surveys and later abstracts. De rubra spatha and its variants sit at the intersection of all three registers.
Researchers working in the Law Mind corpus on related topics — feudal jurisdiction, franchise rights, capital jurisdiction, or the history of the criminal law — should treat this entry as an anchor term connecting Latin franchise vocabulary to its English equivalents.

Historical Dictionary Support
Burrill's Law Dictionary is the sole source on the shelf identifying this term, and its entry is notable for what it does rather than what it says at length. By grouping "Rospear, Rouspee, Rooper, Roper" as the entry head and identifying them as variants of de rubra spatha, Burrill performs the essential work of connecting scattered anglicized forms back to their Latin root. This is precisely the kind of cross-form identification that general historical dictionaries do not provide.
No entry appears in Jacob's Law Dictionary, Bouvier, or Black's for this term or its anglicized variants, which reflects both the term's confinement to medieval English feudal law and its obsolescence well before those dictionaries were compiled. The absence from later dictionaries is itself informative: by the seventeenth century, franchise jurisdictions of this type had been substantially curtailed or absorbed into royal courts, and the vocabulary that described them fell out of practical use.
Researchers should not expect to find substantive doctrinal discussion of this term in any standard legal dictionary outside the medieval specialist literature. Burrill's identification of the variant forms is, for corpus purposes, the key finding.

Jurisdictional Note
De rubra spatha and its variants are exclusively English in their corpus presence, reflecting the particular structure of Anglo-Norman and medieval English feudal franchise law. Analogous concepts of high justice (haute justice) appear in French and continental feudal systems under different terminology and should not be mapped onto this term without careful verification.
