8.2 Defenses, Damages, and Vicarious Liability
Key Takeaways
- Contributory negligence bars all recovery if the plaintiff is even 1% at fault; only AL, MD, NC, VA, and Washington D.C. still use it in 2026.
- 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), and punitive; punitive awards are uninsurable in many states.
- Assumption of risk is a complete defense based on the plaintiff's knowing, voluntary exposure to a specific danger.
- Vicarious liability imputes another's negligence — respondeat superior (employer), family purpose, negligent entrustment, and dram shop are the tested forms.
Defenses That Shift or Reduce Liability
Once negligence is alleged, the defendant's fault rule depends on the jurisdiction. Two systems dominate the exam:
Contributory Negligence (the harsh minority rule)
If the plaintiff is even 1% at fault, recovery is $0. As of 2026 only five jurisdictions 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 rule)
Recovery is reduced by the plaintiff's fault percentage.
| System | Recovery Rule | Approx. # States |
|---|---|---|
| Pure comparative | Recover even at 99% fault, reduced by % | ~13 |
| Modified — 50% bar | Recover only if 50% or LESS at fault | ~10 |
| Modified — 51% bar | Recover only if 50% or LESS; barred at 51% | ~23 |
Worked Comparative-Fault Numerics
These calculations appear almost every exam. Compute the plaintiff's share, then subtract.
- Pure comparative: $200,000 damages, plaintiff 70% at fault. Recovery = $200,000 x (1 - 0.70) = $60,000.
- Modified 50% bar: $100,000 damages, plaintiff 50% at fault -> recovers $50,000; at 51% -> recovers $0.
- Modified 51% bar: $80,000 damages, plaintiff 51% at fault -> recovers $0; at exactly 50% -> recovers $40,000.
Assumption of risk is a separate, complete defense regardless of the comparative system: it bars recovery when the plaintiff knew of a specific danger, appreciated its nature, and voluntarily exposed themselves (a spectator struck by a foul ball, a skier injured on the slopes).
Categories of Damages
Liability limits respond to damages, so know the three buckets:
- Special (economic) damages — objectively measurable: medical bills, lost wages, repair costs.
- General (non-economic) damages — pain and suffering, emotional distress, loss of consortium.
- Punitive damages — awarded for gross negligence or willful misconduct to punish the wrongdoer. Many states make punitive damages uninsurable as a matter of public policy.
Compensatory damages = special + general; they make the plaintiff whole. Punitive damages are not compensatory. On the exam, if a question asks what a standard liability policy pays, the safe answer excludes punitive awards in states that bar their insurability.
Vicarious Liability
Vicarious liability imputes one party's negligence to another because of their relationship — the second party need not have acted negligently itself.
| Doctrine / Relationship | Who Is Held Liable | Trigger |
|---|---|---|
| Respondeat superior | Employer | Employee's negligence within the scope of employment |
| Family purpose doctrine | Vehicle owner / head of household | Family member driving the family car |
| Negligent entrustment | Owner | Lending property to someone unfit to use it safely |
| Dram shop liability | Bar / server | Serving a visibly intoxicated patron who later causes harm |
Scope of employment is the recurring trap: an employer is vicariously liable for acts in furtherance of the job, but generally not for an employee's purely personal "frolic." Independent-contractor acts usually do not impute to the principal.
Joint and Several Liability
When two or more defendants combine to cause a single, indivisible injury, joint and several liability lets the plaintiff collect the entire judgment from any one defendant, who then seeks contribution from the others. This is why a deep-pocket defendant who is only minimally at fault can be forced to pay the whole award.
Example: A $1,000,000 judgment names Driver A (80% at fault) and a municipality (20% at fault). Under pure joint and several liability, the plaintiff can recover the full $1,000,000 from the municipality, which then pursues Driver A for $800,000. Many states have adopted modified rules that limit a defendant's exposure to its own percentage of fault for non-economic damages, so read the scenario for the applicable rule.
Statutes of Limitation and Repose
Two time bars appear on the exam. A statute of limitations sets the period after an injury (or its discovery) within which suit must be filed — commonly two to three years for negligence. A statute of repose sets an outer deadline measured from the defendant's act (such as completion of construction), cutting off claims even if the injury has not yet been discovered. Both directly affect long-tail liability and pair naturally with the claims-made discussion in 8.3.
Choosing the Right Defense on the Exam
Scenario questions reward matching the defense to the jurisdiction and facts:
| If the facts show... | The best defense is... | Effect |
|---|---|---|
| Plaintiff slightly at fault in AL/MD/NC/VA/DC | Contributory negligence | Complete bar (recovery $0) |
| Plaintiff partly at fault in a comparative state | Comparative negligence | Reduces recovery by fault % |
| Plaintiff knowingly accepted a danger | Assumption of risk | Complete bar regardless of system |
| Defendant had the final chance to avoid harm | Last clear chance | Revives a contributorily negligent plaintiff |
Pitfall: comparative negligence rarely produces a $0 result except in modified states once the plaintiff crosses the 50% or 51% threshold. If a question gives a contributory state and any plaintiff fault, the answer is almost always a complete bar.
A plaintiff with $200,000 in damages is found 70% at fault in a PURE comparative negligence state. How much does the plaintiff recover?
An employee negligently injures a customer while making a delivery for the employer. The legal doctrine that holds the employer liable for the employee's negligence is:
