8.2 Defenses, Damages, and Vicarious Liability
Key Takeaways
- Contributory negligence bars recovery for any plaintiff fault; comparative negligence reduces recovery by the plaintiff's percentage of fault.
- Under pure comparative negligence, $100,000 in damages with 30% plaintiff fault yields a $70,000 recovery.
- Compensatory damages = special (economic) + general (non-economic); punitive damages punish and are not compensatory.
- Vicarious liability shifts responsibility to another party — respondeat superior is the leading example for employers.
- An employer escapes vicarious liability when the employee was outside the scope of employment (frolic and detour).
Defenses to Negligence
Even when a claimant proves the four elements, the defendant (and the insurer) can reduce or eliminate liability with affirmative defenses. The state's negligence rule controls how much the plaintiff recovers.
| Defense / Rule | Effect on Recovery |
|---|---|
| Contributory negligence | Plaintiff who is even 1% at fault recovers NOTHING (a few states) |
| Pure comparative negligence | Recovery reduced by plaintiff's % fault, even at 99% |
| Modified comparative (50% / 51% bar) | Plaintiff recovers only if fault is below the threshold |
| Assumption of risk | Plaintiff who knowingly accepted a danger cannot recover |
| Last clear chance | Negligent plaintiff still recovers if defendant had the final opportunity to avoid harm |
Worked numeric: Damages are $100,000 and the plaintiff is 30% at fault. Under pure comparative negligence the plaintiff recovers $70,000 ($100,000 × 0.70). Under pure contributory negligence the plaintiff recovers $0.
Categories of Damages
Liability policies respond to compensatory damages and, where insurable, to legal expenses. Punitive damages are insurable in some states and barred in others.
- Special (economic) damages — objectively measurable: medical bills, lost wages, repair costs.
- General (non-economic) damages — pain and suffering, disfigurement, loss of consortium.
- Punitive (exemplary) damages — punish willful or grossly negligent conduct; awarded above compensatory amounts.
Compensatory = Special + General
Exam phrasing: "Compensatory damages" is the umbrella term that combines SPECIAL (economic) and GENERAL (non-economic) damages. Punitive damages are NOT compensatory — they punish, they do not make the victim whole.
Vicarious Liability
Vicarious liability holds one party legally responsible for the negligent acts of ANOTHER, even though the first party was not directly negligent.
- Respondeat superior — "let the master answer." An employer is liable for an employee's torts committed within the scope of employment.
- Family purpose doctrine — a vehicle owner is liable for negligent use by a family member.
- Dram shop / liquor liability — a bar may be liable for harm caused by a patron it over-served.
- Vicarious parental liability — parents may be liable for a minor child's acts (often capped by statute).
Trap: An employer is NOT vicariously liable for an employee acting outside the scope of employment (a "frolic and detour"). Watch for fact patterns where the employee was on a personal errand.
Defenses to a Negligence Claim
Even where negligence is proven, the defendant may reduce or defeat liability through recognized defenses:
| Defense | Effect |
|---|---|
| Contributory negligence | Any fault by the claimant bars recovery (a few jurisdictions) |
| Comparative negligence | Recovery reduced by the claimant's % of fault (pure or modified) |
| Assumption of risk | Claimant knowingly accepted a known danger |
| Last clear chance | Plaintiff's counter to contributory negligence |
| Immunity / statute of limitations | Governmental immunity; suit filed too late |
Categories of Damages
Liability claims produce three damage types the exam expects you to separate. Special (economic) damages are measurable out-of-pocket losses - medical bills, lost wages, repair costs. General (non-economic) damages compensate intangible harm - pain and suffering, disfigurement, loss of consortium. Punitive (exemplary) damages punish willful, wanton, or malicious conduct; many liability policies and many states exclude or prohibit insuring punitive damages as against public policy.
Vicarious Liability
Vicarious liability imputes one party's negligence to another because of a relationship, without the second party having acted wrongly. Classic examples: an employer liable for an employee's negligence within the scope of employment (respondeat superior); a vehicle owner liable for a permissive driver; and a parent liable for a child under family-purpose or statutory rules. Liability insurance must account for these imputed exposures, which is why the definition of "insured" extends to those vicariously responsible.
Negligence Per Se and Res Ipsa Loquitur
Two doctrines shift the proof burden. Negligence per se treats the violation of a safety statute (running a red light) as automatic breach of duty. Res ipsa loquitur ("the thing speaks for itself") allows an inference of negligence when the harm would not ordinarily occur without negligence and the instrumentality was in the defendant's exclusive control - shifting the burden to the defendant to explain. Both appear as application questions on the casualty portion.
Attractive Nuisance and Premises Duties
Two premises-liability doctrines round out this topic. The attractive nuisance doctrine raises a landowner's duty toward child trespassers drawn onto property by a dangerous condition (a pool, machinery), even though they are technically trespassers. And the modern trend merges the old invitee/licensee/trespasser categories into a general reasonable-care standard in many states.
A candidate should connect these heightened duties to why homeowners and CGL policies are priced for premises hazards, and recognize that punitive damages - though sought in egregious-conduct cases - are frequently uninsurable by statute or public policy, so a liability policy may pay the compensatory award while the insured personally bears any punitive portion.
Mitigation and the Independent-Contractor Limit
Two final points: a claimant has a duty to mitigate damages - failing to take reasonable steps to limit the harm can reduce recovery - and a principal is generally not vicariously liable for the acts of an independent contractor (as opposed to an employee), subject to nondelegable-duty and inherently-dangerous-activity exceptions. Distinguishing an employee from an independent contractor therefore determines whether respondeat superior attaches, a control-test question that recurs in both casualty and workers-compensation fact patterns.
A jury awards $80,000 in damages and finds the plaintiff 40% at fault. In a PURE comparative negligence state, how much does the plaintiff recover?
