8.2 Defenses, Damages, and Vicarious Liability
Key Takeaways
- Pure contributory negligence bars ALL recovery at even 1% plaintiff fault and survives in only five jurisdictions in 2026: AL, MD, NC, VA, and Washington, D.C.
- Comparative negligence reduces recovery by the plaintiff's fault percentage; modified systems bar recovery at the 50% or 51% threshold.
- Damages are special (economic), general (non-economic), punitive (often uninsurable by state law), and nominal.
- Vicarious liability (respondeat superior) makes employers and principals answer for the in-scope torts of employees and agents.
- A hirer is usually NOT vicariously liable for an independent contractor's negligence except for non-delegable or inherently dangerous duties.
Defenses That Bar or Reduce Recovery
Once negligence is alleged, the defendant may raise defenses that eliminate or shrink the claimant's recovery. The fault rule depends on the state, so read scenario questions for the jurisdiction.
Contributory Negligence (the harsh rule)
If the plaintiff is even 1% at fault, recovery is $0. As of 2026, only five jurisdictions use 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 still recover if the defendant had the final opportunity to avoid the harm.
Comparative Negligence (the majority rule)
Recovery is reduced by the plaintiff's percentage of fault.
| System | Recovery Rule |
|---|---|
| Pure comparative | Recover even at 99% fault, reduced by % |
| Modified — 50% bar | Recover only if 50% or LESS at fault |
| Modified — 51% bar | Barred once 51% at fault |
Worked example (pure): $100,000 damages, plaintiff 90% at fault -> recovers $10,000.
Worked example (51% bar): $100,000 damages, plaintiff 51% at fault -> recovers $0; at exactly 50% they would recover $50,000.
Assumption of Risk
Bars recovery when the plaintiff knew of a specific danger, appreciated its nature, and voluntarily accepted it — a spectator struck by a foul ball, or a skier injured on the slopes.
Types of Damages
Damages are the dollars an insurer may owe under the duty to indemnify.
- Compensatory — Special (economic): medical bills, lost wages, repair costs — quantifiable.
- Compensatory — General (non-economic): pain and suffering, emotional distress, loss of consortium.
- Punitive: awarded to punish gross negligence or willful misconduct; many states bar insuring them as against public policy.
- Nominal: a token sum when a right is violated but loss is trivial.
Exam point: Punitive damages are often uninsurable by state law. If a scenario asks what the liability policy will pay after a punitive award, the answer frequently excludes the punitive portion.
Vicarious Liability
Vicarious liability holds one party legally responsible for the negligent acts of another, even though the first party committed no direct wrong. The classic doctrine is respondeat superior ("let the master answer"): an employer is liable for an employee's torts committed within the scope of employment.
Common vicarious-liability relationships:
- Employer–employee — liable for acts within the scope of employment (not for purely personal "frolics").
- Principal–agent — a principal answers for an agent acting within authority.
- Parent–child — many states impose statutory liability for a minor's willful acts, often capped.
- Vehicle owner — owner liability for permissive users under family-purpose or owner-consent statutes.
Independent contractors: A hirer is generally not vicariously liable for an independent contractor's negligence, except for non-delegable duties or inherently dangerous work. The employee-vs-contractor distinction is a frequent exam pivot.
Putting Defenses to Work
The correct defense depends on the fault rule. In a contributory state, slight plaintiff fault is a complete defense — the strongest position for a defendant. In a comparative state, the defense reduces but rarely eliminates recovery, except when the plaintiff crosses the 50% or 51% threshold. Assumption of risk is a separate complete defense in any system because the plaintiff consented to the danger.
The Comparative and Contributory Negligence Rules
The state's fault rule decides how much a partly-at-fault plaintiff recovers, and the exam expects you to compute it:
| Rule | Effect |
|---|---|
| Pure contributory negligence | Any plaintiff fault, even 1%, bars all recovery |
| Pure comparative negligence | Recovery reduced by the plaintiff's % of fault, even if 99% at fault |
| Modified comparative (50%/51% bar) | Plaintiff recovers only if at or below the threshold, reduced by their fault |
Worked example: A plaintiff with $100,000 in damages is found 30% at fault. Under pure or modified comparative negligence the award is reduced to $70,000; under pure contributory negligence the plaintiff recovers $0. Illinois follows a modified comparative (51% bar) rule, so a plaintiff more than 50% at fault recovers nothing.
Categories of Damages
| Type | Purpose |
|---|---|
| Special (economic) | Quantifiable losses — medical bills, lost wages, repair costs |
| General (non-economic) | Pain and suffering, disfigurement, loss of consortium |
| Punitive (exemplary) | Punish willful/wanton conduct; often uninsurable by public policy |
Liability policies pay compensatory (special + general) damages but generally exclude punitive damages, and some states bar insuring them at all.
Vicarious Liability
Vicarious liability holds one party responsible for another's negligence by relationship rather than personal fault. The exam tests the common forms: an employer for an employee's acts within the scope of employment (respondeat superior), a vehicle owner for a permissive driver, and a parent for a minor child under family-purpose or statutory rules. This is why an auto liability policy extends to permissive users and why a business carries coverage for its employees' on-the-job conduct.
Additional Defenses and the Collateral-Source Rule
Defendants may also raise assumption of risk (the plaintiff knowingly accepted a danger), the statute of limitations (suit filed too late), and immunity (governmental or charitable, where it survives). The last clear chance doctrine, conversely, helps a plaintiff: even a negligent plaintiff may recover if the defendant had the final opportunity to avoid the harm. Under the collateral-source rule, payments the plaintiff received from independent sources (health insurance) generally do not reduce the damages owed by the defendant, which preserves the injured party's full claim and the insurer's subrogation interest.
A plaintiff with $100,000 in damages is found 51% at fault in a modified comparative negligence state using the 51% bar. The plaintiff recovers:
A delivery driver negligently injures a pedestrian while making a company delivery. The employer is held responsible. This is an example of:
