Definition
In Roman law, advocates who were not registered or enrolled in the official college of advocates (*collegium advocatorum*) and who were not attached to any particular local jurisdiction. Unlike credentialed members of the bar who held recognized standing within a defined court or territory, supernumerarii operated outside formal registration requirements and the geographic limits those requirements imposed. The term is Latin, meaning literally "those above the number" or "those beyond the roll" — referring to practitioners who existed outside the fixed roster of officially recognized advocates.

Why It Matters in Research
This is a narrow Roman law term with limited direct application in common law research, but it surfaces in two important contexts for Law Mind corpus users.
First, researchers working in Roman law, civil law history, or comparative legal systems will encounter supernumerarii when tracing the early institutional structure of the legal profession — specifically, how advocacy became a regulated, enrolled practice rather than an informal service. The distinction between enrolled and unenrolled advocates maps onto later developments in bar admission, court registration, and the concept of "practice before" a particular tribunal. Understanding supernumerarii helps clarify what the enrolled status was designed to accomplish.
Second, the term appears in historical legal dictionaries as a bridging entry pointing toward related Roman law concepts. Both editions of Black's direct the reader toward *Statuti* (the entry is truncated in surviving sources), suggesting the term was treated as part of a cluster of concepts around advocate regulation. Researchers following cross-references in older editions should be aware the Black's entries for this term are fragmentary — the first edition cuts off mid-cross-reference ("See STA-") and the second edition similarly truncates before completing the citation chain. Do not treat the Black's entries as complete expositions of the term; supplement with Roman law treatises for full treatment.
The term is essentially obsolete in contemporary legal usage. It will not appear in modern statutory codes, case law, or bar regulations. Its research value is historical and comparative only.

Historical Dictionary Support
Both editions of Black's Law Dictionary give substantially identical definitions, identifying supernumerarii as Roman law advocates outside the enrolled college and unattached to local jurisdiction. Neither edition elaborates beyond this core description, and both entries are truncated in their cross-reference lines — a likely artifact of printing or editorial compression in the sources from which Black's drew.
The entries agree on the essential distinction: enrollment in the college of advocates was the normal credentialing mechanism, and supernumerarii were those who practiced without that credential. What the dictionary entries do not address is the practical legal status of such practitioners — whether they were tolerated, restricted, or subject to sanction — or how the category evolved across different periods of Roman legal administration. Researchers needing that context should look beyond the Black's entries to primary Roman law scholarship and Justinianic sources.
No meaningful divergence exists between the two Black's editions on substance; the second edition adds only a brief glimpse of an adjacent entry (*Superoneratio*, concerning surcharge of a common) before its own truncation, which is unrelated to supernumerarii.

Jurisdictional Note
This term belongs exclusively to Roman law and has no direct analog in Anglo-American common law jurisdictions. Civil law systems with Roman law foundations may retain conceptual descendants in bar registration and court admission rules, but the term itself does not appear in modern civilian codes or practice.
