Definition
In Roman law, the rogator was the proposer of a law or rogation — the magistrate or official who formally submitted a proposed measure (a rogatio) to the Roman popular assemblies for a vote. The rogator was typically a consul, praetor, or tribune who initiated legislation by presenting a bill to the comitia or concilium plebis. The term is purely a Roman law concept and does not carry forward as an operative term in any modern common law or civil law jurisdiction.

Why It Matters in Research
ROGATOR appears in historical legal dictionaries primarily as a companion entry to ROGATIO (the proposed law itself) and ROGARE (the act of proposing). Researchers encountering the term in primary or secondary sources on Roman law, or in early civil law treatises translated into English, should treat it as a technical term of Roman constitutional procedure rather than a general-purpose legal concept.
The term is essentially static — its meaning did not evolve or migrate into English common law, equity, or American legal usage. It is not a trap term in the sense of acquiring divergent meanings over time, but researchers should be alert to one navigational risk: early English legal writers borrowing Roman law vocabulary sometimes used rogator loosely to describe any person who "proposes" or "asks" in a formal legal sense, a usage that blurs the Roman constitutional specificity of the term. When encountered outside a Roman law context, verify the author's intent before inferring the technical meaning.
For corpus researchers, ROGATOR is most useful as a gateway into the cluster of related Roman legislative procedure terms. A source that uses rogator precisely is likely drawing on civil law scholarship and may treat neighboring concepts — rogatio, iubere, lex — with corresponding technical care. Burrill cites Taylor's Elements of the Civil Law, a recognizable shelf source, which helps anchor the term's appearance in the Anglo-American treatise tradition.

Historical Dictionary Support
All three source dictionaries are in agreement: ROGATOR means the proposer of a law in Roman law. The definitions are nearly identical across Black's first and second editions and Burrill's entry. No substantive divergence exists among the sources.
Burrill's entry is marginally the most informative, adding the etymology (from rogare) and a citation to Taylor's Elements of the Civil Law at page 195, which gives the term a specific treatise anchor. Black's entries add nothing beyond the core definition. None of the three sources provide context about the Roman constitutional role of the rogator, the assemblies before which rogations were presented, or the procedural consequences of rogatio — gaps that a researcher needing substantive Roman law context will need to fill from dedicated civil law scholarship rather than these dictionary entries alone.
The term's presence across all three dictionaries signals that it was considered sufficiently established in Anglo-American legal reference literature to warrant inclusion, even though it has no practical application outside Roman law and civil law history.
