8.2 Defenses, Damages, and Vicarious Liability
Key Takeaways
- Common-law defenses to negligence include contributory negligence, comparative negligence, assumption of risk, and the statute of limitations — each can reduce or bar a claimant's recovery.
- Pure comparative negligence reduces an award by the claimant's percentage of fault; modified comparative bars recovery once the claimant is 50% or 51% at fault.
- Damages divide into SPECIAL (measurable economic loss), GENERAL (pain and suffering), and PUNITIVE (punishment) — punitive damages are uninsurable in many states as a matter of public policy.
- Vicarious liability holds one party responsible for another's negligence — employer for employee (respondeat superior), principal for agent, and parents for minor children under family-purpose or statute.
- A worked split-limit award shows how 25/50/25 limits cap each bodily-injury claimant, the total per accident, and property damage separately.
Defenses Against a Negligence Claim
Even when a claimant alleges negligence, the defense can reduce or eliminate recovery. The exam tests four classic defenses:
| Defense | Effect on Recovery |
|---|---|
| Contributory negligence | Any fault by claimant (even 1%) BARS recovery — a harsh rule kept in only a few states |
| Comparative negligence | Award reduced by the claimant's percentage of fault |
| Assumption of risk | Claimant knowingly accepted a known danger; bars recovery |
| Statute of limitations | Suit filed after the legal deadline is barred |
Comparative Negligence Math
Most states use comparative negligence. Two variants matter:
- Pure comparative — recovery reduced by the claimant's fault %, even if 99% at fault.
- Modified comparative — recovery barred once the claimant reaches the 50% or 51% threshold.
Worked example: A jury awards $100,000 but finds the claimant 30% at fault. Under pure or modified comparative, recovery = $100,000 × (1 − 0.30) = $70,000. Under old contributory negligence, that 30% fault would bar the ENTIRE claim — $0.
The Three Categories of Damages
When liability is established, the insurer may owe up to three kinds of damages:
- Special (economic) damages — specific, measurable out-of-pocket loss: medical bills, lost wages, repair costs.
- General (non-economic) damages — intangible harm: pain and suffering, disfigurement, loss of consortium.
- Punitive (exemplary) damages — awarded to PUNISH gross or willful misconduct, not to compensate.
Trap: In many states punitive damages are UNINSURABLE as a matter of public policy — letting an insurer pay them would defeat their deterrent purpose. Special + general damages together are compensatory damages.
Split Limits Worked Example
Liability limits are often written as split limits — e.g., 25/50/25 (in thousands):
- $25,000 bodily injury per person
- $50,000 bodily injury per accident (all persons)
- $25,000 property damage per accident
An at-fault insured injures three people — claims of $30,000, $20,000, and $15,000 — and causes $18,000 in property damage.
| Claimant | Claim | Insurer Pays | Reason |
|---|---|---|---|
| Person A | $30,000 | $25,000 | Capped at per-person limit |
| Person B | $20,000 | $20,000 | Under per-person limit |
| Person C | $15,000 | $5,000 | $50,000 per-accident cap reached |
| Property | $18,000 | $18,000 | Under $25,000 PD limit |
Bodily-injury payout stops at the $50,000 per-accident cap; the insured owes the remaining $20,000 personally.
Vicarious Liability
Vicarious liability holds one party legally responsible for another's negligent act:
- Respondeat superior — an employer is liable for an employee's negligence committed within the scope of employment.
- Principal–agent — a principal is liable for acts of an agent acting within authority.
- Family-purpose / parental — a parent may be liable for a minor child's negligent driving or willful damage, often by statute.
Trap: An independent contractor's negligence is generally NOT imputed to the hiring party — unlike an employee's. Control over the work is the deciding factor.
A jury awards a claimant $80,000 and finds the claimant 25% at fault in a pure comparative negligence state. How much does the claimant recover?
Under the doctrine of respondeat superior, which party is held vicariously liable?
Comparative vs. Contributory Negligence Systems
The rule a state uses to allocate fault dramatically changes recovery — a guaranteed exam contrast:
| System | Rule | Effect on a 30%-at-fault plaintiff with $100,000 damages |
|---|---|---|
| Pure contributory | Any plaintiff fault bars recovery | $0 |
| Pure comparative | Recover minus own fault % (even if 99% at fault) | $70,000 |
| Modified comparative (50% bar) | Recover only if < 50% at fault | $70,000 (barred at 50%+) |
| Modified comparative (51% bar) | Recover only if ≤ 50% at fault | $70,000 (barred at 51%+) |
Pennsylvania follows a modified comparative rule (51% bar): a plaintiff who is more than 50% at fault recovers nothing; otherwise damages are reduced by the plaintiff's percentage.
Other defenses: assumption of risk (knowingly accepting a danger) and the last clear chance doctrine (a plaintiff can still recover if the defendant had the final opportunity to avoid the harm).
Trap: under pure contributory negligence, even 1% plaintiff fault bars all recovery — the harshest rule, used in only a few jurisdictions.
A plaintiff with $100,000 in damages is found 30% at fault in a pure comparative negligence state. How much can the plaintiff recover?
Compensatory vs. Punitive Damages and Insurability
Damages fall into categories the exam tests for insurability:
| Category | Subtype | Purpose | Generally insurable? |
|---|---|---|---|
| Compensatory | Special | Reimburse measurable economic loss (medical bills, lost wages, repair) | Yes |
| Compensatory | General | Non-economic loss (pain and suffering, disfigurement) | Yes |
| Punitive (exemplary) | — | Punish/deter egregious conduct | Often uninsurable by public policy in many states |
Liability policies pay compensatory damages the insured is legally obligated to pay. Punitive damages are frequently uninsurable as a matter of public policy because insuring them would defeat their deterrent purpose — though states vary, and some allow coverage for vicariously imposed punitives.
Vicarious liability holds one party responsible for another's torts: employers for employees acting within the scope of employment (respondeat superior), parents for certain acts of minors, and vehicle owners under some states' owner-liability statutes.
Exam tip: special = economic, general = non-economic; both are compensatory and insurable. Punitive damages are often not insurable, a common correct answer in damages questions.
