Definition
A procedural device of Roman law by which a cause was adjourned so that the parties or their advocates could be heard a second time. The comperendinatio was not a continuance in the modern sense of mere postponement, but a structured second hearing built into the proceeding — a deliberate opportunity to revisit argument before the tribunal reached judgment. It reflects the Roman civil procedure's formal architecture of sequential hearings rather than a single consolidated trial.
Common Confusion
Comperendinatio is occasionally conflated with continuance or ampliatio in secondary literature. The distinctions matter:
— A continuance (modern common law) is a postponement of proceedings for scheduling or cause-related reasons, with no structural implication for the form of the subsequent proceeding.
— Ampliatio was a Roman procedural declaration by which judges indicated insufficient evidence to decide, resulting in further inquiry — a different trigger and purpose than the comperendinatio's structured second hearing.
— Comperendinatio specifically contemplated a further hearing of the parties or advocates, implying argument as the object of the adjournment rather than merely additional evidence-gathering.
Why It Matters in Research
This term appears exclusively in discussions of Roman civil procedure and has no direct analog in Anglo-American common law. Researchers will encounter it primarily in:
— Historical treatises on Roman procedure, where it surfaces alongside related terms such as litis contestatio and ampliatio, describing the staged structure of Roman litigation before the praetor and index.
— Secondary legal history scholarship tracing the influence of Roman procedural concepts on canon law and, through canon law, on early civil procedure in civilian jurisdictions.
— Legal dictionaries of the 18th and 19th centuries, which catalogued Roman law vocabulary as part of the general legal education of common lawyers. Its appearance in Black's and Burrill's reflects that encyclopedic tradition rather than any practical application in American courts.
The term carries no jurisdictional relevance to modern U.S. or English legal practice. A researcher finding comperendinatio in a primary source is almost certainly reading a work grounded in Roman law, civilian tradition, or a comparative law discussion. Cross-referencing with the glossaries of Justinian's Digest or Institutes, or with works on Roman civil procedure such as those of Gaius, will provide richer context than any common law source.
Historical Dictionary Support
Black's Law Dictionary (1st and 2nd editions) and Burrill's Law Dictionary are in complete agreement on substance, reproducing essentially identical definitions drawn from the same classical lexicographic sources — Calvinus's Lexicon Juridicum (cited as "Calvin." or "Calv. Lex.") and Brissonius (De Verborum Significatione), both standard reference works of early modern Roman law scholarship. The uniformity across all three dictionary entries signals that none of the editors conducted independent investigation; each inherited the definition through the same chain of civilian lexicography.
What the historical dictionaries do not address: the procedural context within which comperendinatio operated. The term is defined as a result — a second hearing — without explaining the mechanism that triggered it, its relationship to the Roman court's deliberative stages, or how it differed from ampliatio (a related device by which judges declared themselves not satisfied and postponed decision). Researchers should treat the dictionary definitions as a starting point, not a complete account.
