Definition
Latin: "the body with the cause." A historical English writ issuing out of Chancery that directed the removal of both a prisoner's body and the record of the proceedings against him into the Court of King's Bench. The writ was used specifically where a person was lying in execution upon a judgment for debt — meaning he was imprisoned as a consequence of a civil judgment — and its purpose was to bring both the person and the underlying cause before the King's Bench so the matter could be resolved or the judgment satisfied there.
The writ is closely related to, and in later usage often treated as a variant of, the habeas corpus family of writs. Its distinguishing feature is the dual transfer: unlike a simple habeas corpus, which commands production of the body alone, corpus cum causa required the accompanying transmission of the cause — the record, the proceedings, the reason for detention — so the receiving court could act on both.

Common Confusion
Corpus cum causa is frequently grouped with habeas corpus in older sources, and Bouvier's entry simply redirects to HABEAS without further elaboration. The confusion is understandable but imprecise. Habeas corpus in its modern form compels production of the body to test the legality of detention; corpus cum causa historically served a more specific procedural function — the removal of a civil debt-execution prisoner together with his case record to a higher court. The two writs share a root concern (restraint of liberty), but corpus cum causa was an instrument of jurisdictional transfer rather than a direct challenge to the lawfulness of confinement. Researchers encountering the term in pre-nineteenth-century English sources should not assume it operates identically to habeas corpus as that writ is understood today.

Why It Matters in Research
This is an extinct procedural writ of English origin with no modern analog in American or contemporary English practice. Researchers will encounter it almost exclusively in historical sources — early chancery practice materials, Fitzherbert's Natura Brevium (the reference Rapalje & Lawrence cites as "F. N. B. c. 21"), Cowell's Interpreter, and Blount's Nomo-Lexicon — rather than in case reporters or statutes.
The primary research trap is treating corpus cum causa as synonymous with habeas corpus. Bouvier's cross-reference to HABEAS, without qualification, can mislead a researcher into conflating the two. Burrill is more careful, noting the habeas corpus connection only secondarily and flagging it as an applied or extended usage rather than a definitional equivalence.
Because the writ operated in the civil debt-execution context, it belongs to the history of imprisonment for debt — a practice abolished in England by statute during the nineteenth century and never firmly established in most American jurisdictions. Researchers tracing the history of debtor's imprisonment, Chancery jurisdiction, or the evolution of habeas corpus will find corpus cum causa a useful marker of the older, more fragmented writ system that preceded modern remedies.
Note also that Rapalje & Lawrence's entry drifts mid-paragraph into corpus delicti and corpus juris — a typographical artifact of historical dictionary formatting that can cause confusion in transcribed or digitized versions. The corpus cum causa entry ends with the description of the prison-removal writ; what follows is a separate entry.

Historical Dictionary Support
The four source dictionaries are largely in agreement on the core definition, and the variation among them is instructive rather than contradictory.
Black's and Burrill offer the fullest definitions and are substantively identical, both tracing the writ to Cowell and Blount as authority. Burrill adds the secondary note connecting the writ to habeas corpus for cause removal, signaling awareness that by the time these dictionaries were compiled the writ had been largely absorbed into or displaced by habeas corpus practice.
Bouvier's silence — a redirect to HABEAS — reflects the nineteenth-century American tendency to consolidate the old English writ taxonomy under habeas corpus as that remedy expanded in scope. It is not a definition so much as a jurisdictional concession that corpus cum causa had ceased to function independently in American legal practice.
Rapalje & Lawrence confirm the Fitzherbert citation, grounding the writ in the oldest layer of English practice manual authority, but the entry's typographical bleed into adjacent terms limits its utility as a standalone source.
No source offers a reported case in which the writ was successfully deployed, and none distinguishes precisely between corpus cum causa as a Chancery original and its use as a habeas variant. Historical dictionaries are uniformly silent on any American usage.

Jurisdictional Note
Corpus cum causa is an English writ with no established American counterpart. American courts developed habeas corpus as the primary liberty writ without adopting the parallel Chancery mechanism for civil debt removal. The writ is therefore relevant to American legal research only in comparative, historical, or choice-of-law contexts involving colonial-era or early federal practice.
