Definition
A Latin phrase meaning "I have commanded the bailiff." In English practice, mandavi ballivo was the formal return made by a sheriff to the court when a writ had been delivered for execution not by the sheriff directly, but by the bailiff of a liberty — a local officer with independent jurisdiction over a defined territory — who held the right to execute writs within that liberty. The return signified that the sheriff had fulfilled his duty by issuing the command to the appropriate officer; execution itself was in the bailiff's hands.
Where the bailiff had not yet responded, the sheriff's return would note this explicitly: mandavi ballivo, qui nullum dedit responsum — "I have commanded the bailiff, who gave no answer." Where the bailiff had made a return, the sheriff was expected to transmit that return to the court.
Why It Matters in Research
This term belongs to the procedural machinery of the English writ system, specifically the layer of complexity introduced by liberties — jurisdictional enclaves (typically held by a lord or ecclesiastical body) where ordinary royal officers could not act directly. Researchers working in English legal history, particularly before the nineteenth-century reforms that abolished or consolidated many of these liberties, will encounter mandavi ballivo as a routine sheriff's return in plea rolls, procedural records, and chancery files.
The critical research trap is treating this return as a completed execution. It is not. Mandavi ballivo signifies transmission of authority, not performance. A writ returned with this phrase tells you only that the sheriff acknowledged a liberty's jurisdiction and passed the command along — not that the writ was ever served or enforced. The companion return (qui nullum dedit responsum) is the marker that the process stalled at the bailiff level, which has procedural consequences researchers should track separately.
This term does not translate into modern American practice. The office of bailiff of a liberty, and the interlocking return system it generated, was a feature of English common law procedure that American jurisdictions did not transplant in any meaningful form. Researchers using this term in an American context will find it only in historical treatises, comparative law sources, or discussions of colonial-era procedure that drew on English models.
For procedural sequence, Tidd's Practice (cited in both editions of Black's and in Burrill) remains the standard reference point for understanding how this return functioned in the broader context of writ execution and sheriff's duties.
Historical Dictionary Support
All five source dictionaries agree on the core definition: this is the sheriff's return announcing that the bailiff of a liberty holds execution authority over the writ in question. The Latin gloss — "I have commanded" or "I have made my mandate to the bailiff" — is consistent across Black's (both editions) and Burrill.
Rapalje & Lawrence adds the most procedural texture, noting the two possible sub-returns depending on whether the bailiff has responded: the bare mandavi ballivo where a response is pending, and the fuller mandavi ballivo, qui nullum dedit responsum where the bailiff has been silent. This distinction is absent from the other four dictionaries but is practically important for understanding the return system.
Bouvier frames the definition slightly differently, emphasizing that the bailiff holds the right to execute the writ — foregrounding the jurisdictional basis of the liberty rather than the sheriff's act of commanding. This is a useful complement to the other definitions, which emphasize the sheriff's action. Neither framing is wrong; they describe the same return from different angles.
No source provides significant historical depth beyond this procedural snapshot. None traces the term's origins, its prevalence in particular periods of English legal history, or how the practice was affected by the gradual erosion of liberties under nineteenth-century reform legislation. Researchers needing that context must go beyond the standard dictionaries to primary sources and legal historians of the English common law.
Jurisdictional Note
Mandavi ballivo is exclusively an English common law term. The legal structure it presupposes — the bailiff of a liberty with independent writ-execution rights — did not take root in American jurisdictions, which organized sheriffs' duties along different lines. The term appears in American legal dictionaries for historical and comparative completeness, not because it describes any living American practice.
