Definition
In Roman law, pauperies is the damage or injury caused by an irrational animal (one lacking reason) acting without provocation or fault on the part of the owner. The term describes a specific form of civil liability in which the owner of a domesticated animal was obligated to compensate the victim for harm caused — not because the owner was personally at fault, but because the animal was under the owner's control and custody.
The liability arose from the animal's nature, not from any negligence or wrongful act of the owner. Because an animal was considered incapable of committing a wrong in the legal sense, the wrong could not be attributed to the animal itself. Instead, Roman law imposed a noxal obligation on the owner: the owner could either pay damages or surrender the animal to the injured party (noxae deditio).
Common Confusion
Pauperies is easily misread as deriving from paupertas (poverty or destitution), and Burrill notes that the Latin root pauper (poor) has no bearing on the technical legal meaning. The term has nothing to do with indigency, poor persons, or the in forma pauperis doctrine. Researchers encountering pauperies in a Roman law context should resist any association with poverty-related legal concepts. The confusion is compounded by the fact that the Latin derivation is misleading even to trained readers of the language.
Why It Matters in Research
Pauperies is a term of pure Roman law with no direct common-law counterpart. It will not appear in American or English case reporters as a live legal standard, but it is essential for researchers working in:
— Roman law foundations of tort doctrine, particularly the actio de pauperie, which was the procedural vehicle for pursuing pauperies claims under the Digest and Institutes;
— Comparative law analysis of strict liability and animal owner liability, where pauperies is frequently invoked as a historical antecedent to modern strict liability rules for dangerous animals;
— Legal history sources covering the reception of Roman law into civil law jurisdictions, where pauperies concepts survived into continental European codes;
— Secondary treatises on the law of torts, particularly those addressing whether early common law borrowed from Roman strict liability principles.
The key research trap is anachronism: modern strict liability for animal attacks is often described as having Roman roots in pauperies, but the doctrinal transmission to common law is contested. Common law developed its own parallel doctrines (the "one-bite rule," scienter, and later statutory strict liability) largely without formally adopting the Roman framework. Researchers should be cautious about overstating the genealogical connection.
Within the Law Mind corpus, pauperies appears primarily in Roman law surveys, civil law treatises, and foundational jurisprudence texts. It is unlikely to appear in American primary sources except as a reference point in scholarly commentary.
Historical Dictionary Support
The four source dictionaries agree on the core meaning — damage done by an irrational animal, with owner liability notwithstanding absence of personal fault — but differ in depth and emphasis.
Black's (both editions) provides the most condensed account, pointing to the Institutes (4.9) and Mackeldey's Roman Law as authority. Neither edition explains the noxal surrender option or the philosophical underpinning of the doctrine.
Rapalje & Lawrence adds a useful behavioral gloss absent from Black's: the damage typically arose from a sudden willfulness in the animal, occasioned by instinct or excitement (such as heat). This specification helps distinguish pauperies from harm caused by a vicious animal known to its owner — the latter potentially invoking different liability principles.
Burrill provides the most jurisprudentially complete account. He explicitly addresses the philosophical problem: an irrational animal cannot commit a wrong (injuria), so the damage is damnum sine injuria facientis datum — loss without wrong on the part of the doer. He cites both the Institutes (4.9) and the Digest (9.1.1.3), and notes the absence of any English common-law counterpart, which is the most practically important observation in any of the entries.
None of the historical dictionaries addresses the actio de pauperie as a standalone procedural concept, nor do they connect pauperies to the later development of noxal liability in comparative or civil law contexts. Researchers needing that layer of analysis should proceed to Roman law treatises directly.
Jurisdictional Note
Pauperies as a doctrine is specific to Roman law and has no operative status in American or English common law jurisdictions. Its relevance in modern research is primarily historical and comparative. Civil law systems derived from Roman law (including French, Spanish, and Italian traditions) carry doctrinal descendants of pauperies in their animal liability provisions, though not always under that name.
