8.2 Defenses, Damages, and Vicarious Liability
Key Takeaways
- Comparative negligence reduces a claimant's recovery by their own percentage of fault; pure contributory negligence can bar recovery entirely.
- Damages divide into compensatory (special and general) and punitive; punitive damages are often uninsurable by statute or public policy.
- Special damages are economic and provable (medical bills, lost wages); general damages are non-economic (pain and suffering).
- Vicarious liability holds one party responsible for another's negligence, most commonly an employer for an employee acting in the course of employment.
- Common negligence defenses include assumption of risk, the statute of limitations, and intervening cause.
Defenses that reduce or defeat a claim
Even when the four negligence elements seem present, the defendant can raise defenses that shrink or eliminate liability. The liability insurer funds the defense (defense costs are typically outside the limit on the CGL) and asserts these on the insured's behalf.
- Contributory negligence (pure form) — if the claimant is even 1 percent at fault, recovery is completely barred. Only a few jurisdictions still use this harsh rule.
- Comparative negligence — recovery is reduced by the claimant's own percentage of fault. Most states use this.
- Assumption of risk — the claimant knowingly accepted a known danger (e.g., a spectator hit by a foul ball).
- Statute of limitations — the claim was filed after the legal deadline.
- Intervening cause — a later, unforeseeable event broke the chain of causation.
Comparative negligence math
Assume a claimant proves 100,000 dollars in damages but is found 30 percent at fault.
| System | Calculation | Claimant recovers |
|---|---|---|
| Pure comparative | 100,000 x (1 - 0.30) | 70,000 dollars |
| Modified (50 percent bar) | 30 percent < 50 percent threshold, reduce | 70,000 dollars |
| Pure contributory | Any fault bars recovery | 0 dollars |
Now flip it: if the claimant were 60 percent at fault, pure comparative still pays 40,000 dollars, but modified comparative (50-percent or 51-percent bar) pays 0 because the claimant's fault meets or exceeds the bar. Read the fact pattern for which system applies.
Categories of damages
| Damage type | Subtype | Meaning | Example |
|---|---|---|---|
| Compensatory | Special (economic) | Provable out-of-pocket loss | 8,000 dollars medical bills, 2,500 dollars lost wages |
| Compensatory | General (non-economic) | Intangible loss | Pain and suffering, disfigurement |
| Punitive (exemplary) | — | Punish and deter willful or grossly negligent conduct | Awarded above compensatory damages |
Key trap: punitive damages are frequently uninsurable by state statute or public policy, because allowing insurance to pay them would defeat their deterrent purpose. A worked award of 50,000 dollars special + 75,000 dollars general + 200,000 dollars punitive may leave only the 125,000 dollars compensatory portion insurable where punitive coverage is barred.
Vicarious liability and respondeat superior
Vicarious liability makes one party legally responsible for the negligent acts of another, even though the first party did nothing wrong directly. The doctrine of respondeat superior ("let the master answer") holds an employer liable for an employee's negligence committed within the course and scope of employment.
This is why the CGL covers the named insured's liability for its employees' work, and why non-owned and hired auto exposures and independent contractor relationships are tested. A principal can also be vicariously liable for an agent's acts. Note the limit: an employer is generally not vicariously liable for an employee's intentional or clearly off-duty acts (the "frolic and detour").
A claimant proves 100,000 dollars in damages but is found 40 percent at fault. The state uses pure comparative negligence. How much can the claimant recover?

Negligence Defenses and Fault-Allocation Rules
Defendants reduce or defeat liability through recognized defenses, and the exam tests how each state's fault rule changes recovery:
| Doctrine | Effect on Recovery |
|---|---|
| Pure contributory negligence | Any fault by the claimant (even 1%) bars all recovery |
| Pure comparative negligence | Recovery reduced by the claimant's own percentage of fault |
| Modified comparative (50%/51% bar) | Recovery barred once the claimant's fault reaches the threshold |
| Assumption of risk | Voluntarily accepting a known danger bars recovery |
| Statute of limitations | Suit filed too late is barred |
| Last clear chance | Lets a negligent claimant recover if the defendant could have avoided the harm |
Under pure comparative negligence, a claimant 30% at fault with $100,000 damages recovers $70,000; under pure contributory negligence, that same 30% fault bars the entire claim.
Damages and Vicarious Liability
Damages divide into three categories the exam separates carefully. Special (compensatory-economic) damages are provable out-of-pocket losses - medical bills, lost wages, repair costs. General (compensatory-non-economic) damages compensate pain, suffering, and disfigurement. Punitive damages punish egregious conduct and are often uninsurable by statute or public policy, so a liability policy frequently will not pay them.
Vicarious liability imputes one party's negligence to another because of their relationship - most commonly an employer for an employee acting in the course of employment (respondeat superior), or a vehicle owner for a permitted driver. The negligent party need not be the one sued; the responsible party's liability policy responds. This is why an employer's CGL can be triggered by an employee's on-the-job negligence even though the employer was not personally careless.
A claimant who is 40% at fault for an accident has $50,000 in damages. In a pure comparative negligence state, how much can the claimant recover?
Why Punitive Damages Often Escape Coverage
The exam draws a sharp line around punitive (exemplary) damages. Unlike compensatory damages, which restore the claimant, punitive damages are meant to punish the defendant for willful, wanton, or grossly negligent conduct and to deter repetition. Many states hold that allowing insurance to pay punitive damages would defeat their deterrent purpose, so coverage is barred by statute or public policy. When a verdict splits an award into compensatory and punitive portions, the liability policy typically pays the compensatory part (special plus general damages) and the insured personally absorbs the punitive part.
This interacts with the negligence categories: ordinary negligence rarely supports punitive damages, but gross negligence or intentional misconduct can - and that same conduct may also fall outside the policy's coverage for expected or intended injury. Recognizing that a single verdict can contain both insured and uninsured components is a common test point that links damages, exclusions, and public policy together.
