8.2 Defenses, Damages, and Vicarious Liability
Key Takeaways
- Contributory negligence bars all recovery for any plaintiff fault; pure comparative reduces recovery by the fault percentage; modified comparative bars recovery only at/above a 50% or 51% threshold.
- Damages fall into special (economic), general (non-economic), and punitive categories; compensatory = special + general, while punitive damages are often uninsurable.
- Vicarious liability transfers fault through a relationship — respondeat superior makes employers answer for employees within scope of employment.
- Independent contractors generally do not create vicarious liability for the hiring firm.
- Joint and several liability lets a plaintiff collect the full judgment from any one at-fault defendant, distinct from vicarious liability.
Defenses Against a Negligence Claim
Even where negligence is proven, the defendant can reduce or eliminate liability through recognized defenses. The exam tests how each affects the recovery dollar figure.
| Defense | Effect | State adoption |
|---|---|---|
| Contributory negligence | Plaintiff who is even 1% at fault recovers nothing | Few states (harsh rule) |
| Comparative negligence — pure | Recovery reduced by plaintiff's % fault, even at 99% | Several states |
| Comparative negligence — modified (50%/51% bar) | Plaintiff recovers only if fault is below the bar (50% or 51%) | Most states |
| Assumption of risk | Plaintiff knowingly accepted a known danger — bars recovery | Many states |
| Last clear chance | Plaintiff recovers despite own negligence if defendant had the final opportunity to avoid harm | Contributory states |
Worked Example — Comparative Negligence
A jury awards $100,000 and finds the plaintiff 30% at fault.
- Pure comparative: $100,000 × (1 − 0.30) = $70,000 recovered.
- Modified (51% bar): plaintiff is under the bar, so the same $70,000 is recovered.
- Contributory negligence: any plaintiff fault bars recovery → $0.
If the plaintiff had been 55% at fault: pure comparative still pays $45,000; modified-51% pays $0 (over the bar); contributory pays $0.
Categories of Damages
Damages are what liability policies actually pay. Know the three categories:
- Special (economic) damages — measurable out-of-pocket losses: medical bills, lost wages, repair costs.
- General (non-economic) damages — pain and suffering, disfigurement, loss of consortium; harder to quantify.
- Punitive (exemplary) damages — awarded to punish gross or willful misconduct. Many states bar insurers from covering punitive damages on public-policy grounds; the exam treats punitive damages as frequently uninsurable.
Special + general damages together are compensatory — they make the victim whole. Punitive damages go beyond making whole.
Vicarious Liability
Vicarious liability holds one party responsible for the negligent acts of another because of a relationship between them — even though the responsible party did nothing wrong directly.
- Respondeat superior ("let the master answer") — an employer is liable for an employee's negligence committed within the scope of employment. A delivery driver who rear-ends a car on the route makes the employer vicariously liable.
- Independent contractors — generally do not create vicarious liability for the hiring firm, the key exam distinction from employees.
- Family/auto — under family-purpose doctrine or owner consent statutes, a vehicle owner can be liable for a permissive user's negligence.
Vicarious vs. Joint and Several Liability
Do not confuse the two. Joint and several liability lets a plaintiff collect the entire judgment from any one of multiple at-fault defendants (often the "deep pocket"), who then seeks contribution from the others. Vicarious liability transfers fault up a relationship; joint and several allocates a shared judgment among co-defendants.
Statutes and Damage Caps
Beyond the common-law defenses, two statutory limits shape liability claims. A statute of limitations bars a claim filed after a set period (often two to four years for negligence, measured from injury or discovery). A statute of repose bars claims after a fixed period from a product's sale or a building's completion, regardless of when injury occurs.
Some jurisdictions also impose damage caps on non-economic or punitive damages. These limits matter to insurers because they bound the potential judgment. The exam may give a claim filed years after the loss and ask why it is barred — the answer is the statute of limitations, an absolute defense independent of fault.
Compensatory vs. Punitive — Insurability
Damages divide into compensatory (which restore the victim) and punitive (which punish the wrongdoer). Compensatory damages split further into special/economic (medical bills, lost wages, repair costs — objectively measurable) and general/non-economic (pain and suffering, disfigurement, loss of consortium).
Liability policies pay compensatory damages the insured is legally obligated to pay. Punitive damages raise an insurability question: many states bar insurers from covering them on public-policy grounds, reasoning that letting insurance absorb the punishment defeats its deterrent purpose. The exam treats punitive damages as frequently uninsurable — when a scenario awards punitive damages, expect the policy to exclude or be barred from paying them.
Immunities and Releases
Beyond comparative-fault rules, certain parties enjoy immunity that bars or limits liability claims: governmental immunity (waived in part by tort-claims acts with caps), and charitable immunity in a few jurisdictions. A signed release or waiver (a gym membership waiver) can also defeat a negligence claim, though courts will not enforce waivers of gross negligence or those against public policy. The exam may give a plaintiff who signed an activity waiver and ask whether ordinary negligence is barred — generally yes, while reckless conduct is not.
Worked Example — Joint and Several Allocation
Three defendants are found liable for a $300,000 judgment, apportioned 60/30/10. Under joint and several liability, the plaintiff may collect the entire $300,000 from the 60%-at-fault "deep pocket," who then seeks contribution of $90,000 and $30,000 from the others. Under a several-only (proportionate) system, each pays only its share ($180,000 / $90,000 / $30,000) and the plaintiff bears the risk of an insolvent defendant. Distinguishing these allocation rules from vicarious liability — which transfers one party's fault to another through a relationship — is the core tested concept.
Mitigation of Damages
A plaintiff has a duty to mitigate — to take reasonable steps to limit the harm. A claimant who refuses reasonable medical treatment, or who lets covered property worsen, cannot recover the additional, avoidable loss. This doctrine caps damages independent of the defendant's fault and pairs with the comparative-fault rules to determine the final recoverable figure.
A jury awards $80,000 and finds the plaintiff 40% at fault. In a PURE comparative negligence state, how much does the plaintiff recover?
