What it does
The Animals Act 1977 (NSW) is a short but surgically targeted statute that excises several archaic common-law doctrines concerning animals from the law of New South Wales and replaces them with a default to ordinary principles of tort and occupiers' liability. Its core operative provisions fall into three conceptual blocks.
First, Part 2 abolishes two medieval remedies. Section 4(1) extinguishes the tort of cattle-trespass outright. The abolition is not total: s 4(2) expressly preserves (a) statutory references to "trespassing animals", (b) the tort of trespass by a person using cattle as the instrument, and (c) the law governing an occupier's liability for death of or injury to trespassing cattle. Section 5 abolishes the common-law remedy of distress damage feasant—the right to seize and impound an animal found damaging land until compensation is paid.
Second, Part 3 rewrites the substantive law of liability. The definitional section (s 6) is deceptively short but important: "liability" is confined to damages in tort; "occupier" is deliberately tied to the existing law of occupiers' liability; and "premises" is given an expansive meaning that includes land, fixed or movable structures, vessels, aircraft and vehicles. Section 7(1) states that liability for damage caused by an animal is henceforth governed by "so much of the law relating to liability as does not include the common law abrogated by subsection (2)". Subsection (2) then abolishes any common-law rule, qualification, restriction, exclusion, extension or imposition that (a) existed immediately before commencement and (b) related exclusively to liability for damage caused by an animal. The abolition is sweeping: it catches rules based on scienter (knowledge of vicious propensity), rules about animals versus , and any special rules that applied when animals escaped onto highways.
