8.2 Defenses, Damages, and Vicarious Liability
Key Takeaways
- Contributory negligence is the harsh rule — a plaintiff even 1% at fault recovers $0; only Alabama, Maryland, North Carolina, Virginia, and Washington D.C. still apply it as of 2026.
- Comparative negligence reduces (pure) or may bar (modified 50%/51% rule) recovery in proportion to the plaintiff's share of fault — the majority approach.
- Damages are compensatory (special/economic + general/non-economic) or punitive; many states bar insuring punitive damages as against public policy.
- Vicarious liability makes one party responsible for another's negligence — employer for employee (respondeat superior), and owners for permissive drivers.
- Assumption of risk and statutes of limitations are additional defenses that defeat or time-bar a negligence claim.
Defenses That Reduce or Defeat a Claim
Contributory Negligence (the harsh rule)
If the plaintiff is even 1% at fault, recovery is $0. As of 2026, only five jurisdictions still apply pure contributory negligence: Alabama, Maryland, North Carolina, Virginia, and Washington D.C. A narrow escape hatch is the last clear chance doctrine, which lets a contributorily negligent plaintiff recover if the defendant had the final opportunity to avoid the harm.
Comparative Negligence (the majority approach)
Most states reduce recovery in proportion to the plaintiff's fault rather than barring it outright:
| Type | Rule | Result |
|---|---|---|
| Pure comparative | Recover minus your % fault, even at 99% | 90% at-fault plaintiff still recovers 10% |
| Modified 50% | Barred if your fault is 50% or more | Recover only if 49% or less at fault |
| Modified 51% | Barred if your fault exceeds 50% | Recover if 50% or less at fault |
Worked Allocation Examples
Pure comparative: A plaintiff with $100,000 in damages is found 30% at fault. Recovery = $100,000 x (1 - 0.30) = $70,000.
Modified 51% rule: Same $100,000 damages, but the plaintiff is 55% at fault. Because 55% exceeds 50%, recovery = $0 — the plaintiff is barred.
Modified 50% rule: Plaintiff with $80,000 damages is exactly 50% at fault. Under the 50% rule, a plaintiff who is 50% or more at fault is barred, so recovery = $0. (Under the 51% rule the same plaintiff would recover $40,000.)
Trap: Watch the threshold wording. "50% rule" bars at 50%; "51% rule" allows recovery at exactly 50% and bars only above it. Exam questions hinge on this single percentage point.
Other Defenses
- Assumption of risk — the plaintiff knowingly and voluntarily accepted a known danger (e.g., a spectator hit by a foul ball).
- Statute of limitations — a claim filed after the legal deadline is time-barred regardless of merit.
In a pure comparative negligence state, a plaintiff with $200,000 in damages is found 40% at fault. What does the plaintiff recover?
Types of Damages
Damages are what the liability policy ultimately pays. The exam tests these categories closely.
- Compensatory — Special (economic): quantifiable losses — medical bills, lost wages, repair and replacement costs.
- Compensatory — General (non-economic): intangible harm — pain and suffering, emotional distress, loss of consortium.
- Punitive (exemplary): intended to punish egregious or willful conduct, not to compensate. Many states bar insuring punitive damages as against public policy, so a policy may pay the compensatory award but not the punitive portion.
- Nominal: a token sum when a legal right is violated but actual loss is trivial.
Exam phrasing: "Punitive damages are uninsurable in many states" is a near-certain test statement. Special = economic/quantifiable; general = non-economic/intangible.
Vicarious Liability
Vicarious liability makes one party legally responsible for the negligent acts of another, based on the relationship between them rather than the first party's own conduct.
| Relationship | Doctrine | Example |
|---|---|---|
| Employer / employee | Respondeat superior | Delivery driver causes a crash within the scope of employment; the employer is liable |
| Vehicle owner / permissive user | Permissive use / owner liability | Friend you lend your car to causes an accident |
| Parent / minor child | Statutory family liability | Many states hold parents liable for a minor's willful acts up to a cap |
For respondeat superior to apply, the employee must be acting within the scope of employment. An employee on a personal "frolic" outside work duties generally breaks the employer's vicarious liability. This is why CGL and commercial auto forms extend coverage to employees acting within their duties.
A pizza company's driver, while delivering an order during a shift, runs a stop sign and injures a pedestrian. Under which doctrine is the pizza company liable for the driver's negligence?
Why the Punitive-Damage Exclusion Matters
Because punitive damages punish rather than compensate, public policy in many states forbids shifting that punishment onto an insurer — letting a wrongdoer insure away the consequence of egregious conduct would defeat deterrence.
Worked example: A jury awards a claimant $300,000 compensatory and $1,000,000 punitive against an insured in a state that bars insuring punitive damages. The liability policy (with adequate limits) pays the $300,000 compensatory award; the insured personally owes the $1,000,000 punitive portion. Where state law allows coverage and the policy does not exclude it, the insurer may pay both.
Trap: Do not assume the full verdict is payable. Split the award — compensatory is generally insurable; punitive often is not. The answer key usually rewards identifying the compensatory-only payment.
Statutory Liability That Overrides Common Law
Several statutes create or shift liability beyond ordinary negligence, and the exam expects you to recognize them.
- Dram shop laws make a business that sells alcohol liable for injuries caused by a patron it served while intoxicated — a third party can sue the bar, not just the drunk driver.
- Workers' compensation is an exclusive-remedy, no-fault system: the employer pays statutory benefits regardless of fault, and the employee generally cannot also sue the employer for negligence.
- Joint and several liability lets a plaintiff collect the entire judgment from any one of several at-fault defendants (the "deep pocket"), who then seeks contribution from the others.
Exam point: Under joint and several liability, a defendant only 10% at fault can still be forced to pay 100% of the judgment if the co-defendants are insolvent. Many states have modified this for low-fault defendants.
