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?
$0
$20,000
$60,000
$80,000
Under the doctrine of respondeat superior, which party is held vicariously liable?
The employee for the employer's acts
The employer for an employee's negligence within the scope of employment
The insurer for the insured's intentional acts
The independent contractor for the hiring firm's debts
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?
$0, because the plaintiff was partly at fault
$30,000
$70,000
$100,000
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.
