Definition
In Roman civil law, judigatio (also sometimes rendered judicatio) is the act of judging — specifically, the formal pronouncement of a sentence or judgment by a magistrate or judge after a cause has been heard and deliberated upon. It denotes the concluding act of the adjudicative process: the authoritative declaration that resolves the dispute before the tribunal. The term is a Latin technical expression drawn directly from Roman procedural law and does not survive as a term of art in modern common law systems.

Common Confusion
Judigatio should not be confused with the broader Latin term judicium, which refers to the judicial proceeding or the court itself, nor with sententia, which refers to the opinion or verdict as a substantive matter. Judigatio is specifically the act of pronouncing — the performative, procedural moment of judgment delivery — rather than the content of the judgment or the forum in which it occurs. Researchers encountering any of these terms in civil-law-influenced texts should be careful not to treat them as interchangeable.

Why It Matters in Research
This term appears almost exclusively in sources treating Roman or civil law procedure and is unlikely to appear in common law materials except where authors are consciously borrowing civilian vocabulary. Its presence in a legal text is a strong signal that the author is working within or drawing upon the civilian tradition — making it a useful index term for identifying the intellectual lineage of a source.
The Black's Law Dictionary supplemental entry cites Hallifax's Civil Law (Book 3, Chapter 8, No. 7), which is an important reference point. Researchers working in early American or colonial legal materials may encounter judigatio in treatises that used civilian sources as foundational authorities, particularly in jurisdictions such as Louisiana, Quebec-influenced territories, or ecclesiastical and admiralty contexts where civil law held purchase alongside or above common law.
Because judigatio appears in the supplemental rather than the main body of Black's 2nd Edition, researchers should treat it as a term the editors regarded as specialized, archaic, or peripheral to everyday practice — useful for glossing historical texts but not part of the active working vocabulary of courts at the time of publication.
No modern statutory or case law corpus is likely to use this term directly. Its research value is almost entirely historical and comparative.

Historical Dictionary Support
The sole historical dictionary source available is the Black's Law Dictionary (2nd Ed.) supplemental entry, which defines judigatio concisely as "judging; the pronouncing of sentence, after hearing a cause," with attribution to Hallifax's Civil Law. The entry is brief and descriptive, making no effort to distinguish judigatio from related concepts or to trace its procedural significance within the Roman system.
The Hallifax citation — Samuel Hallifax, Analysis of the Roman Civil Law (various editions, 18th century) — is a real and identifiable source, a standard English-language introduction to Roman law used in legal education during the period. Researchers seeking fuller treatment of judigatio as a concept should consult Hallifax directly, as Black's does not elaborate beyond the one-line gloss.
No other major historical legal dictionaries in the Law Mind corpus appear to have included this term, which confirms its status as a technical civilian term of limited circulation in common law reference works.

Jurisdictional Note
Judigatio as a technical term has no operative meaning in American common law jurisdictions. It retains relevance in research contexts touching Louisiana civil law history, ecclesiastical law, admiralty procedure, and comparative law scholarship rooted in the Roman and Continental traditions.
