Definition
Placita is the plural of placitum. The term carried several distinct meanings across Roman civil law and medieval English law, and a researcher encountering it must determine from context which sense applies:
1. Imperial decrees (civil law). In Roman and civil law usage, placita referred to the constitutive acts of the emperor — decrees, rescripts, and constitutions that carried legal force by virtue of the imperial will. The formulation quod principi placuit ("what pleases the prince") was the theoretical source of their authority.
2. Public assemblies (old English law). In early English law, placita denoted the great assemblies of the realm over which the sovereign presided, where matters of state and governance were deliberated. These were not courts of law in the modern sense but political and consultative bodies.
3. Pleas, pleadings, and trials. By extension — and most commonly in legal records — placita referred to formal legal proceedings: pleas, pleadings, debates, and trials at law. This is the sense most frequently encountered in medieval plea rolls and court records.
4. Penalties and financial exactions. In exchequer usage, placita could denote fines, penalties, mulcts, and monetary emendations — the fiscal outcomes of legal proceedings recorded in the accounts of the royal treasury.
5. Court style (nisi prius records). Placita also appeared as the formal style or heading of the court at the opening of nisi prius trial records. This usage was largely ceremonial and had fallen out of practice by the time the major historical dictionaries were compiled.
Common Language
Modern common usage (Wiktionary): Plural of placitum.
Historical common usage (Webster's 1913): No entry. The term was not in general English circulation.
This is pure legal and ecclesiastical Latin with no meaningful presence in ordinary English. The Wiktionary entry is accurate but circular. Researchers encountering placita in documents need the full matrix of legal senses above, not a Latin declension note.
Recognized Forms
/SUBTYPES
Placita coronae: Pleas of the crown; criminal proceedings. Distinct from civil suits and recorded separately in crown plea rolls.
Placita communia: Common pleas; civil actions between subjects, as distinguished from crown pleas. The institutional distinction between these two categories is fundamental to understanding medieval English court structure and jurisdiction.
Why It Matters in Research
The word placita functions as a structural marker in medieval legal records, and its meaning shifts depending on document type. A researcher working in plea rolls will encounter it in sense 3 (pleadings and trials); a researcher in exchequer records may find it in sense 4 (fines and financial penalties); a researcher in civil law or canon law texts will need sense 1 (imperial decrees).
The subtypes placita coronae and placita communia are particularly important navigational terms. They map directly onto the jurisdictional division between King's Bench (crown pleas) and Common Pleas (common pleas) — a division that structured the English common law court system for centuries. Misreading a reference to placita coronae as a generic term for pleadings will obscure the criminal or crown dimension of the proceeding.
The nisi prius usage (sense 5) is a trap for researchers reading trial records. The opening formula including placita was formulaic and carries no substantive legal information; its presence tells you the document type, not the content.
Historical sources vary in how completely they capture all five senses. Researchers relying on a single dictionary source risk missing the exchequer or assembly meanings entirely.
Historical Dictionary Support
The sources are in close agreement on the core meanings but differ in emphasis and completeness.
Black's (both editions) and Rapalje & Lawrence follow Cowell closely, presenting the English law senses — assemblies, pleas, penalties, and nisi prius style — as a cluster without clearly differentiating their contexts. This is useful for orientation but can blur distinctions that matter in practice.
Burrill's Law Dictionary is the most analytically useful source here. It explicitly disaggregates placita coronae (crown pleas) and placita communia (common pleas) as recognized subcategories, and it traces the civil law sense to Calvin's Lexicon and Brissonius, providing the theoretical grounding in quod principi placuit. Burrill also connects the exchequer usage to the Liber Niger Scaccarii (Black Book of the Exchequer) and Coke's Littleton, giving the penalties sense an institutional context the other dictionaries omit.
None of the historical sources adequately explain the relationship between the term's civil law and common law lives. A researcher encountering placita in a text with mixed civil and common law influences — canon law materials, for example, or early equity proceedings — will need to triangulate between both traditions and should not assume that the English-law cluster of meanings applies.
Jurisdictional Note
The civil law senses of placita have relevance primarily in civil law jurisdictions, Roman law scholarship, and canon law research. In English and American common law contexts, the term appears almost exclusively in historical records; it carries no operative legal meaning in modern practice.
