- Modified comparative fault: 51% bar under 42 Pa.C.S. § 7102
- Premises liability: Pennsylvania uses the invitee/licensee/trespasser framework with specific duty levels
- Dog bite law: Pennsylvania is a hybrid — strict liability for medical costs; negligence required for other damages
- Sovereign immunity: Pennsylvania government entities have broad immunity; waived only for specific situations under 42 Pa.C.S. § 8522
Pennsylvania personal injury law operates within the modified comparative fault framework and includes important Pennsylvania-specific doctrines around government immunity, premises liability, and dog bite law. Pennsylvania's government immunity law — which waives sovereign immunity only for nine specific categories of government negligence — is more protective of government defendants than in many states. Pennsylvania's dog bite law is a hybrid that imposes strict liability for medical costs but requires proof of negligence (or knowledge of vicious propensity) for pain and suffering damages.
Premises Liability in Pennsylvania
Pennsylvania follows the Restatement (Second) of Torts approach to premises liability, with duties based on visitor status:
- Business invitees: highest duty — property owner must inspect the premises, discover hazards, and either correct them or provide adequate warning. The duty is ongoing and active.
- Licensees: property owner must warn of known dangers not reasonably apparent. No duty to inspect or discover unknown hazards.
- Trespassers: generally no duty except to refrain from willful or wanton injury. Child trespassers are protected by the attractive nuisance doctrine.
Pennsylvania courts apply a reasonable care standard for invitees, which requires not just actual knowledge of a hazard but constructive knowledge — the property owner should have discovered it through reasonable inspection. Retail stores, shopping malls, and restaurants are held to active inspection standards, not merely reactive response to reported hazards.
Pennsylvania Dog Bite Law: Hybrid Liability
Pennsylvania's dog bite law (3 P.S. § 459-502) creates a hybrid liability standard: (1) strict liability for medical costs resulting from a dog bite — no prior vicious propensity need be shown, and the owner is liable for medical expenses from the first bite; (2) negligence standard (or knowledge of vicious propensity) for all other damages, including pain and suffering. This means a dog bite victim can recover medical bills easily under strict liability but must prove either the owner was negligent in controlling the dog or knew of the dog's dangerous history to recover non-economic damages. Pennsylvania's hybrid approach is different from both pure strict liability states (California) and pure one-bite-rule states.
Pennsylvania Government Immunity
Pennsylvania has broad sovereign immunity for state agencies under 42 Pa.C.S. § 8521, waived only for specific categories of negligence listed in § 8522: vehicle liability; care, custody, or control of personal property; real property; trees, traffic controls, and street lighting; utility service facilities; streets; sidewalks; care, custody, or control of animals; and liquor store sales. Claims outside these nine categories are immune from suit. Local government immunity (42 Pa.C.S. § 8541–8545) provides similar protection with overlapping but slightly different waivers. All government tort claims must be filed within 6 months of the injury (or the date the injured party knew or should have known of the injury) under 42 Pa.C.S. § 5522 — a significantly shorter deadline than the general 2-year personal injury SOL.
