Definition
In Roman and civil law, *ordinarius* (adjective) denotes that which is ordinary, regular, or conducted according to the established course and rule of law — as distinguished from proceedings or powers that are extraordinary, delegated, or granted by special dispensation. The term appears most prominently as a modifier in classical civil law procedure, where it distinguishes the standard forms of judicial process from exceptional or abbreviated alternatives.
As a noun, *ordinarius* also designates a judge or officer who holds jurisdiction by virtue of office — that is, by right of the position itself rather than by special commission or delegation. In ecclesiastical law this usage became particularly important: a bishop or archbishop acting as *ordinarius* exercises original, inherent jurisdiction over his diocese, as opposed to jurisdiction exercised by a delegate or commissary.
The two principal uses are therefore:
1. ORDINARIUS (adjective): Of or belonging to the regular order; according to ordinary rule and procedure. Applied to judgments, actions, and processes that follow the established sequence of civil law pleading and adjudication.
2. ORDINARIUS (noun): An officer or judge who possesses jurisdiction in his own right — by office, not by delegation. Most commonly encountered in ecclesiastical contexts as a title for diocesan bishops and their equivalents.
Common Confusion
Do not conflate *ordinarius* with the English derivative "ordinary" as used in American or English ecclesiastical and probate law. While the English "ordinary" descends directly from the Latin *ordinarius*, the two terms operate in different legal systems and carry subtly different institutional freight. In English and American practice, "ordinary" often refers specifically to the probate judge or surrogate who exercises jurisdiction over wills and estates — a usage that has no precise Roman law antecedent. Researchers finding *ordinarius* in a Latin civil law text are reading about civil procedure or inherent jurisdictional authority, not necessarily about probate courts.
Why It Matters in Research
Researchers will encounter *ordinarius* primarily in three contexts within the Law Mind corpus, each requiring separate attention.
First, in translated or annotated civil law texts — Justinian's Corpus Juris Civilis and the commentaries upon it — *ordinarius* marks the distinction between the classical *ordo judiciorum privatorum* (the ordinary system of private litigation) and the later *cognitio extraordinaria* (extraordinary procedure). Understanding which system a source is describing is essential to interpreting the procedural rules discussed; ordinary and extraordinary procedure differed in pleading, evidence, and the role of the magistrate.
Second, in ecclesiastical law sources — canon law compilations, ecclesiastical court records, and treatises on church government — *ordinarius* as a noun designates the officer with original territorial jurisdiction. Sources dealing with episcopal authority, ecclesiastical discipline, or church courts will use the term to identify who holds power to act versus who acts only as a delegate. Conflating ordinary and delegated jurisdiction here produces serious misreadings.
Third, in historical English legal sources that borrow civilian terminology, "ordinary" and *ordinarius* may appear interchangeably or in deliberate contrast. Readers should note which legal tradition — common law, civil law, or ecclesiastical — is governing a given source, because the institutional referent shifts accordingly.
A practical trap: Burrill's entry for *ordinarius* appears truncated in surviving text, cutting off mid-sentence at the description of civil procedure. Researchers relying solely on Burrill will miss the full procedural context. Cross-referencing civil law encyclopedias and Sandars or Hunter on Roman law will complete the picture.
Historical Dictionary Support
Burrill's Law Dictionary provides the essential foundation: *ordinarius* derives from *ordo* (order) and signifies what is ordinary, regular, and according to usual course. Burrill's entry specifically illustrates *ordinaria judicia* — ordinary trials or actions — as proceedings in which the regular sequence of pleading and litigation was observed: first the proceedings *in jure* (before the magistrate on questions of law), then the proceedings *apud judicem* (before the judge on questions of fact). This two-stage structure was the hallmark of classical Roman procedure under the formulary system and distinguished ordinary litigation from the later extraordinary cognition in which a single imperial official handled the entire proceeding.
Burrill's entry is unfortunately truncated, leaving the full definition incomplete. This is a notable gap. The term's use as a noun — the *ordinarius* as a judge holding inherent jurisdiction — is not addressed in the surviving Burrill text, though it is well attested in other historical legal dictionaries and in the civil and canon law sources Burrill elsewhere cites.
Other historical legal dictionaries (Tomlin's, Jacob's) address the English derivative "ordinary" at length in the context of ecclesiastical and probate jurisdiction, confirming the continuity between the Latin *ordinarius* and the institutional role it named. The convergence across sources on the core meaning — inherent, non-delegated authority exercised according to established order — is consistent and reliable.
Jurisdictional Note
*Ordinarius* as a Latin term belongs primarily to civil law and ecclesiastical law traditions. Its direct institutional relevance is greatest in jurisdictions with a civil law heritage (Louisiana, Quebec, Scotland) and in canon law. In common law jurisdictions, the functional successor concept appears under the English term "ordinary," which carries its own jurisdiction-specific meaning in probate and ecclesiastical court contexts.
