Definition
CITATION carries two distinct legal meanings that researchers must distinguish by context.
1. Procedural citation (process/summons). A writ or official notice issued by a court or tribunal commanding a named person to appear before it on a specified date, either to perform some act or to show cause why they should not. Historically the primary instrument of the ecclesiastical and admiralty courts, it functions analogously to a common-law summons or chancery subpoena — it is the mechanism by which a court obtains jurisdiction over a party or brings a matter to their attention. In modern American practice, the term survives in probate proceedings (citing heirs or creditors to appear), family law (citation to show cause), traffic enforcement (a citation issued by a police officer in lieu of arrest), and regulatory enforcement (an OSHA citation directing an employer to correct a violation).
2. Reference citation (legal authority). The act of referring to a case, statute, regulation, treatise, or other legal authority in support of a legal proposition, or the notation that identifies that source with sufficient precision to locate it. This is the dominant modern usage in legal writing. A proper legal citation identifies the source (court, reporter, volume, page, year) following an accepted citation format — in U.S. practice, most commonly The Bluebook or ALWD Citation Manual.
Common Language
Modern common usage (Wiktionary): An official summons or notice given to a person to appear; the act of quoting a passage from a text and crediting the original source; an entry in a list of sources following a bibliographical style.
Historical common usage (Webster's 1913): An official summons or notice to appear; the act of citing a passage from a book or another person in their own words; a reference to decided cases or books of authority to prove a point.
The common and legal meanings overlap more here than with most legal terms, but the gap is meaningful in two respects. First, in ordinary English "citation" for a source reference is largely interchangeable across disciplines and carries no formal requirements; in legal practice, a citation must conform to prescribed formats, and an improperly formed citation can draw court sanctions or be disregarded. Second, the procedural citation — a writ compelling appearance — has no meaningful counterpart in general English usage today, even though it remains a live legal instrument.
Recognized Forms
/SUBTYPES
Procedural citation. A writ or notice issued by a tribunal commanding appearance or action. Includes probate citations, show-cause citations, ecclesiastical citations, and regulatory citations (e.g., OSHA enforcement actions).
Traffic/infraction citation. An enforcement notice issued by a law enforcement officer requiring the recipient to appear in court or pay a fine, used in lieu of physical arrest for minor violations.
Reference citation. A notation in a legal document — brief, memorandum, opinion, or treatise — identifying the authority relied upon for a proposition of law.
Subsequent history citation. In legal research, a citation that tracks what happened to a previously cited case on appeal or remand — essential for verifying that cited authority remains valid.
Why It Matters in Research
The dual meaning creates a persistent classification problem in the Law Mind corpus. A historical source discussing "citation practice" may be discussing either how courts compel appearance or how advocates reference authority — and the same treatise may address both without distinguishing them by section heading. Researchers pulling ecclesiastical or admiralty materials will encounter citation almost exclusively in the procedural sense; researchers in legal writing or appellate practice materials will encounter it almost exclusively as a reference tool.
Temporal shift matters. Through most of the 19th century, the procedural meaning dominated legal dictionaries. The reference-citation meaning was treated as secondary or merely noted in passing. The modern inversion — where "citation" in legal discourse defaults to the reference meaning — is largely a 20th-century development driven by the formalization of citation systems and the growth of appellate practice literature.
Regulatory citation is a distinct third track that researchers working in administrative and employment law must keep separate. An OSHA citation, for example, is not merely a summons — it is also a charging document that specifies the violation, the applicable standard, and the proposed penalty. Conflating it with either the general procedural citation or the reference citation produces analytical errors.
For corpus researchers: when a historical source uses "citation" without qualification, check the surrounding context for ecclesiastical, admiralty, or probate proceedings before assuming it means a case reference.
Historical Dictionary Support
Black's (both editions) leads with the procedural meaning — a writ commanding appearance — and treats the reference meaning as secondary. Burrill is more historically precise, tracing the term explicitly to the ecclesiastical courts and noting its analogues in common law (capias, summons) and equity (subpoena). Burrill also preserves the Scots law usage, where citation by an officer of court was the formal act beginning litigation — a usage distinct from both the English ecclesiastical model and modern American practice.
Rapalje & Lawrence's entry in the source material as provided does not address citation directly; the excerpt appears to be a fragment concerning circumstantial evidence, likely a retrieval error or catalog mismatch. Researchers should not rely on that entry for citation doctrine.
What the historical dictionaries collectively miss: they do not address the reference-citation meaning in any systematic way, reflecting the era in which they were compiled. The modern apparatus of citation formats, citation services, and citator tools (Shepard's, KeyCite) lies entirely outside their frame. This is a significant gap for researchers who encounter historical discussions of "proper citation" expecting guidance on reference form — the sources will not deliver it.
Jurisdictional Note
The procedural citation survives most robustly in probate and family courts, where practice varies by state. In federal practice, the term appears in admiralty and in the procedural rules governing writs of error and certiorari. Regulatory citations (OSHA and analogues) are creatures of federal and state administrative law and carry their own procedural frameworks distinct from court-issued citations.
