Definition
In old English and Roman-influenced legal Latin, *deliberatio* carries two distinct senses that appeared in medieval English legal usage:
1. **Delivery.** The act of formally handing over a thing — property, goods, a person, or a writ — to another. In this sense *deliberatio* functions as a Latin equivalent of the English term *delivery*, and Burrill directs readers to the related entry *Liberatio* for fuller treatment.
2. **Acquittal or discharge.** The formal release of a person from legal liability, accusation, or custody. In this sense the term denotes a juridical act that clears or discharges an accused party.
Both senses turn on the idea of release or transfer: in the first instance, of a thing; in the second, of a person from legal jeopardy.

Common Confusion
The Latin root *deliberare* also gives English the word "deliberate" (to weigh, consider, or reflect), and modern readers encountering *deliberatio* in a historical legal text may instinctively read it as referring to deliberation — that is, the process of careful consideration, as by a jury. That reading is almost always wrong. In its legal-Latin usage, *deliberatio* denotes an *outcome* (delivery or discharge), not a cognitive *process*. A jury deliberates (*deliberat*); a court that enters a *deliberatio* delivers or acquits. Researchers working in medieval English legal records must resist the modern cognate trap.

Why It Matters in Research
**Structural pattern:** This term follows the historical evolution pattern — a Latin legal term absorbed into medieval English practice, documented in Bracton, and largely absent from modern usage. Its research significance is almost entirely historical and philological.
**Corpus navigation.** *Deliberatio* will surface chiefly in Latin-language records and treatises from the medieval English common law tradition — plea rolls, eyre records, and works in the tradition of Bracton (*De Legibus et Consuetudinibus Angliae*). Burrill's citation to Bracton fol. 143b is the primary anchor. Researchers using the Law Mind corpus should treat this term as a Latin-record term and search accordingly; it will not appear meaningfully in post-medieval English-language legal materials.
**The delivery sense.** When *deliberatio* means delivery, it overlaps functionally with *traditio* (transfer of possession in Roman law) and with the English law concept of livery of seisin. Distinguishing which concept a source intends requires attention to context — whether the subject matter is corporeal property, a writ, or a person.
**The acquittal sense.** When *deliberatio* means discharge or acquittal, it connects to the broader cluster of Latin terms for release from criminal process in medieval English law, including *quietus*, *liberatio*, and *acquietatio*. The specific Bracton citation (fol. 143b) addresses criminal procedure contexts. Researchers tracing the history of acquittal doctrine in English law may encounter this term as a formal designation for discharge before the modern vocabulary of acquittal was standardized.
**Absence from later sources.** The term does not appear in Blackstone, in the major 19th-century American law dictionaries (Bouvier, Black), or in equity practice literature. Its absence from those sources is itself informative: by the time English legal writing shifted fully to the vernacular, *deliberatio* had been superseded by plain English equivalents. Finding the term in a document is therefore a reliable signal of a medieval or early modern Latin source.

Historical Dictionary Support
Burrill's entry is brief and cross-referential, directing readers from the delivery sense to *Liberatio* and anchoring the acquittal sense in Bracton. The entry does not develop either meaning at length, and Burrill himself appears to treat *deliberatio* as a secondary or variant form rather than a term of primary doctrinal weight.
No entry appears in the other standard historical dictionaries (Bouvier, Black's early editions, Jacob's Law Dictionary, Tomlin's) indexed in the Law Mind corpus for this term — which reinforces its status as a term of art from Latin-language sources rather than from the mainstream Anglo-American common law commentary tradition.
The Bracton citation is genuine and substantive. Bracton's *De Legibus* is the foundational 13th-century Latin treatise on English law, and references to acquittal and discharge appear in its treatment of criminal procedure. Researchers who wish to examine the acquittal sense in context should consult the Bracton text directly at the cited foliation.
