How it applies
Common Examples
6
Contributory Negligence No Bar
Seth Shapiro keeps a tiger on his rural property for a roadside attraction. Stella Shapiro walks near the enclosure despite posted warnings and is gored after leaning over the fence. Stella's decision to approach the enclosure constitutes contributory negligence, yet she recovers damages from Seth because that defense does not apply to strict liability for wild animals.
Private Plaintiff Defamation Claim
Sarah Sullivan, a local pediatrician who occasionally speaks at town halls, sues a blog for falsely accusing her of insurance fraud in an article on a matter of public concern. The blog published the statements without verifying key facts. Sarah may recover only upon showing at least negligence by the blog. Strict liability is unavailable under constitutional limits.

Knowing Risk Assumption Defense
Sasha Stone enters an enclosure housing an abnormally dangerous domestic animal despite clear posted warnings that contact is prohibited. The animal injures Sasha after she reaches over the fence. Sasha's conduct of knowingly and unreasonably subjecting herself to the risk bars recovery under the strict liability rule.
Assumption of Risk Bars Recovery
Sofia Stern voluntarily enters a tiger enclosure at a private zoo after signing a waiver acknowledging the danger. The tiger attacks and injures Sofia. Her assumption of the risk of harm from the animal defeats the strict liability claim against the zoo owner.
Voluntary Exposure to Activity Risk
Sterling Manufacturing conducts aerial pesticide spraying on its fields. Selena Singh remains outdoors on her adjacent property repairing equipment despite posted notices and prior warnings to stay inside during flights. Wind shifts the spray onto Selena, causing injury. Her voluntary and unreasonable exposure to the known risk of drifting chemicals bars recovery on strict liability grounds.
No Strict Liability to Trespasser
Sierra Solutions maintains a tiger on its fenced industrial site. Sasha Stone intentionally climbs the fence at night to photograph the animal and is attacked. Sasha has no claim for strict liability against Sierra Solutions because the rule does not impose liability to one who intentionally trespasses on the land.
Common questions
Frequently Asked
4
When does contributory negligence fail to bar recovery under strict liability for animals or abnormally dangerous activities?+
Contributory negligence does not bar recovery except when the plaintiff voluntarily and unreasonably subjects himself to the risk of harm from the animal or activity. The rule places the loss on the party who chose to keep the animal or conduct the activity rather than on the victim.
Does assumption of the risk defeat a strict liability claim for harm from a wild animal?+
Yes. The plaintiff's assumption of the risk of harm from the animal is a complete defense to strict liability. This defense applies even when ordinary contributory negligence would not bar recovery.
Is strict liability available against a trespasser injured by an animal kept on the land?+
No. A possessor of land is not subject to strict liability to one who intentionally or negligently trespasses for harm done by a wild animal or abnormally dangerous domestic animal kept on the land.
Why is strict liability forbidden in defamation actions by private plaintiffs on matters of public concern?+
The First Amendment requires at least a showing of negligence before a private plaintiff may recover compensatory damages. Strict liability would violate constitutional limits that protect speech on public issues while still allowing recovery when fault is proven.
