UBIQUITY

Definition

The state of being present everywhere, or in multiple places, simultaneously. In legal usage, ubiquity most commonly appears in the doctrine of **legal ubiquity of the sovereign** — a fiction of English common law by which the monarch is treated as constructively present in every court of the realm at once, since all judicial authority flows from the Crown. The practical consequence of this fiction is that justice is administered in the king's name throughout the jurisdiction, and the sovereign cannot be said to be absent from any court where that authority operates.

Common Language

Modern common usage (Wiktionary): The state or quality of being, or appearing to be, everywhere at once; actual or perceived omnipresence. Historical common usage (Webster's 1913): Existence everywhere, or in places, at the same time; omnipresence — applied to the omnipresence of God, and also to Luther's theological doctrine that Christ's glorified body is omnipresent. The common meaning and the legal meaning are not far apart, but the gap is specific and important: in ordinary usage, ubiquity is a factual or metaphysical description. In law, it is a legal fiction — a deliberate, artificial construct that assigns a quality (omnipresence) to a legal person (the sovereign) not because it is literally true, but because the legal system needs it to be treated as true for jurisdictional and procedural purposes.

Why It Matters in Research

Ubiquity as a standalone legal term is rare in modern legal writing. Researchers encountering it are almost certainly reading historical materials — English common law treatises, early American constitutional commentary, or cases touching on Crown prerogative and its American successors. The key navigational point: legal ubiquity of the sovereign is the entry point into a cluster of interrelated doctrines — sovereign immunity, the source of judicial power, and the procedural fictions that governed how courts were constituted and how writs ran throughout a jurisdiction. When Blackstone invokes legal ubiquity in the Commentaries (1 Bl. Comm. 270), he is explaining why the king's courts are the king's courts even when the king is nowhere near them. American courts translating Crown prerogative into republican doctrine had to either transplant or consciously discard this fiction. Researchers working on early American jurisdictional questions should watch for ubiquity language being used to ground arguments about the reach of state authority or the constructive presence of the sovereign in lower courts — arguments that often appear without the word "ubiquity" itself, making the conceptual connection easy to miss. The term also appears in theological and philosophical sources that were in active circulation among early legal thinkers. Webster's 1913 flags Luther's doctrine of ubiquity. This cross-contamination of theological and legal omnipresence language is not accidental — natural law writers drew on both registers, and historical legal sources may use ubiquity in ways that blend the metaphysical and the jurisprudential.

Historical Dictionary Support

The three historical dictionaries converge on the core definition — omnipresence or presence throughout a jurisdiction — but they differ meaningfully in depth and framing. Black's first edition offers the bare definition without elaboration. Black's second edition adds the critical application: the specific English legal fiction of royal ubiquity, with a direct cite to Blackstone. This is the entry that earns its place; it gives the researcher the doctrine and the primary source in one line. Anderson's entry is the most developed but arrives in fragmentary condition in the source text — the entry appears to be truncated mid-sentence ("legal ubiqSee..."). What survives is nonetheless instructive: Anderson frames ubiquity in the context of the king as the fountain of justice, connects it to the prerogative power, and points toward Roman law sources (Hadley, Maine, Gibbon) that inform the broader doctrine of sovereign authority dispensing justice throughout a dominion. Anderson also cites Vance v. Vance, 108 U.S. 514 (1883), and Senseman's Appeal, 21 Pa. 333 (1853), suggesting that the doctrine had live application in American courts as late as the 1880s — though researchers should examine those cases directly to confirm the specific connection Anderson intended, given the truncated state of the entry. What the historical dictionaries do not address: the jurisdictional fiction of ubiquity in the context of criminal law, where the "ubiquity doctrine" appears in some modern systems to determine which jurisdiction may prosecute when a crime has elements occurring in multiple places. This is a distinct usage that postdates the historical dictionary entries and will not be found under this term in the shelf sources.

Jurisdictional Note

Legal ubiquity as a royal prerogative doctrine is a concept native to English common law and its American inheritors. In American constitutional law the fiction dissolved into structural doctrine — the judicial power of the United States, or of a state, rather than the constructive presence of a sovereign person. Researchers working in civilian or civil law jurisdictions will find the royal ubiquity doctrine absent, though analogous concepts of jurisdictional reach appear under different terminology.
