Definition
A Roman law, attributed to a lex passed during the Republican period, that permitted a prosecution for theft (furtum) to proceed without the participation or intervention of the property owner. Under general Roman law principles, the victim of theft was ordinarily the necessary party to bring a criminal or quasi-criminal action. The Lex Hostilia de Furtis created an exception: where the owner was absent, held captive, or otherwise unable to act, the prosecution could go forward independently of the owner's direct involvement. The law thus separated the prosecutorial function from the personal grievance of the injured party, marking an early step toward the public enforcement of wrongs that had previously been treated as purely private matters.
Common Confusion
The term is sometimes loosely grouped with Roman private law remedies for theft — particularly the actio furti, the civil action available to the owner — but the Lex Hostilia operated in a distinct register. The actio furti was a private remedy pursued by the owner for a monetary penalty; the Lex Hostilia addressed the criminal or quasi-public prosecution of the thief, and specifically solved the procedural problem that arose when no owner was present to initiate or sustain it. Conflating the two obscures a meaningful distinction between Rome's parallel private and public responses to theft.
Why It Matters in Research
This term appears almost exclusively in historical legal sources dealing with Roman criminal procedure or the comparative history of theft law. Researchers are unlikely to encounter it in case law or statute outside of scholarly or antiquarian contexts. Its primary research value is in understanding the Roman doctrinal roots of the principle that criminal prosecution of theft need not depend on the victim's active participation — a principle that resurfaces in debates over public prosecution, victim standing, and the evolution of the state's role in criminal enforcement.
When tracing that lineage in Law Mind sources, note that the Lex Hostilia tends to appear as a brief illustrative reference rather than a subject of extended analysis. Rapalje & Lawrence's entry is itself thin, pointing to Stephen's Commentaries as the substantive source. Researchers working backward from common law discussions of theft or larceny who encounter this term should treat it as a Roman antecedent citation, not as a governing authority.
The reference to 4 Stephen's Commentaries (7th edition, p. 118) is the specific location to consult for the most developed common law discussion of the Lex Hostilia in the Law Mind corpus. James Fitzjames Stephen used the law as a historical data point in examining the structure of theft prosecutions, and his treatment is more expansive than any of the standard Roman law dictionaries of the period.
Historical Dictionary Support
Rapalje & Lawrence provide the only dictionary entry encountered in the Law Mind shelf, and it is deliberately spare: a single sentence identifying the law's subject matter and a pointer to Stephen's Commentaries. No divergence among sources is possible to assess given the singularity of coverage. What this sparseness itself signals is significant — the term was treated by Victorian legal lexicographers as a historical curiosity requiring only identification, not analysis. Researchers should not expect richer treatment in contemporaneous Roman law dictionaries such as those of Smith or Bouvier; the term falls in the gap between Roman law specialists (who would address it in treatise form, not dictionary form) and common law practitioners (for whom it was purely antiquarian).
The law's name follows the standard Roman legislative naming convention: lex plus the name of the proposing magistrate (Hostilius) plus the subject matter (de furtis, concerning thefts). The historical identity of the proposing Hostilius is uncertain and not material to legal research use of the term.
Jurisdictional Note
No jurisdiction applies this term as operative law. Its relevance is entirely historical and comparative, appearing in sources treating Roman law as a backdrop to common law development.
