Definition
Roy is a Law French and Anglo-Norman term meaning "the king." It appears in medieval English legal maxims and writs as the standard designation for the Crown, functioning not as a personal name but as a title of sovereign authority. In historical legal usage, roy carries the full weight of royal prerogative, franchise power, and sovereign immunity.
The term appears principally in two contexts in the historical record:
1. As a component of Latin-French legal maxims asserting royal authority, prerogative, and the king's relationship to law and statute.
2. As part of the writ ROY POET DISPENSER (see below), which addressed the jurisdictional limits of the royal household courts.
Common Language
Modern common usage (Wiktionary): "Roy" in contemporary English is a male given name of Scottish Gaelic origin, or a surname from multiple linguistic traditions. It carries no inherent royal connotation in modern ordinary usage.
Historical common usage (Webster's 1913): "A king. [obs.]" — marked obsolete even by 1913.
The gap is total. A researcher encountering "roy" in a legal manuscript, plea roll, or maxim is reading a term of legal sovereignty, not a personal name. The common English meaning had already faded to obsolescence before modern legal scholarship began, meaning researchers without Law French training may misread the term entirely.
Common Confusion
Roy is frequently invisible to researchers who encounter it in Law French maxims because it looks like an Anglo-Norman given name rather than a legal term of art. The maxim "Roy n'est lie per ascun statute si il ne soit expressment nosme" — the king is not bound by any statute unless expressly named — is among the most consequential principles in English constitutional history, yet a reader unfamiliar with Law French may not recognize that "Roy" is the operative legal subject, not a person's name. Similarly, "Roy est l'original de touts franchises" encodes the foundational franchise theory of the common law. Misreading "roy" as a proper noun rather than the sovereign destroys the meaning of these maxims entirely.
Why It Matters in Research
Researchers working in pre-nineteenth century English legal sources — Year Books, Coke's Institutes, Fitzherbert, Brooke, Keilway, Jenkins' Centuries, Rolle's Abridgement — will encounter "roy" with regularity in maxims, writs, and abridgements. The following navigational points apply:
First, the maxim "Roy n'est lie per ascun statute si il ne soit expressment nosme" is a live doctrine, not merely a historical curiosity. The principle that the Crown is not bound by a statute unless expressly named persists in modified form in English law and in Commonwealth jurisdictions. Researchers tracing this canon of statutory construction backward from modern cases will find its Law French root in Jenkins' Centuries and Broom's Legal Maxims.
Second, the franchise maxim "Roy est l'original de touts franchises" underlies the entire common-law theory that franchises (including borough charters, market rights, and later corporate charters) derived their legitimacy from royal grant. This connects directly to quo warranto proceedings and the history of corporate chartering. Researchers approaching franchise law or corporate history from the English common-law side need this entry point.
Third, the Bouvier entry references a distinct writ — one lying against a steward or marshal for holding plea in the royal household court for matters not arising within the household. This is a jurisdictional writ limiting the reach of the court coram rege or the Marshalsea, and it is distinct from the broader maxim tradition. Researchers studying the Marshalsea, the court of the Steward and Marshal, or the development of the common law's resistance to prerogative courts should treat this as a separate research thread.
Fourth, Law French sources index inconsistently. "Roy" may appear as "roi," "rei," or "le roy" depending on the manuscript tradition and the transcriber's conventions. Corpus searches on a single spelling will miss variants.
Historical Dictionary Support
Black's Law Dictionary preserves "roy" as a Law French headword and supplies two maxims in their original form with translation: the franchise maxim from Keilway 138 and the statute-binding maxim from Jenkins' Centuries 307 (also cited to Broom's Legal Maxims). It then opens, but does not complete in the excerpt, the maxim "Roy poet dispenser ove malum prohibitum, mais non malum per se" — the king can dispense with a malum prohibitum but not a malum per se. This maxim is among the most important in the history of royal dispensing power and the constitutional crises of the seventeenth century. The truncation in the source material is a research hazard; the full maxim must be located in Jenkins or Broom directly.
Bouvier's entry shifts entirely to the procedural: a writ, its occasion, and its citation to Wharton. Bouvier does not engage the maxim tradition at all. The two dictionaries are therefore complementary rather than redundant — Black's covers the maxim and prerogative dimensions; Bouvier's covers the writ and procedural dimension.
Neither dictionary discusses the decline of Law French as a pleading language or the transition point at which "roy" ceased to appear in live legal documents. Researchers should note that Law French was formally abolished in English courts by statute in 1731, but maxims citing "roy" continued to appear in treatises and judicial opinions as doctrinal shorthand well into the nineteenth century.
Jurisdictional Note
The "roy" maxims are English common-law sources. They carry direct relevance in Commonwealth jurisdictions that inherited English common law, particularly regarding the Crown-not-bound canon of statutory interpretation. In the United States, the franchise-as-royal-grant theory influenced early American corporate law but was substantially reframed after independence; "roy" maxims appear in early American treatise literature but are cited for historical pedigree rather than as binding authority.
