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 D.C. use it in 2026.
- Comparative negligence reduces recovery by the plaintiff's fault percentage — pure, modified 50% bar, or modified 51% bar.
- Damages are special (economic), general (non-economic), and punitive; punitive damages are uninsurable in many states.
- Strict (absolute) liability imposes responsibility without proof of fault for abnormally dangerous activities, defective products, and certain statutes.
- Vicarious liability (respondeat superior) holds employers, parents, and vehicle owners responsible for another party's negligence based on the relationship.
Defenses to a Negligence Claim
Even when a plaintiff proves all four DBCD elements, the defendant may reduce or eliminate liability with a recognized defense. The three the exam tests are contributory negligence, comparative negligence, and assumption of risk.
Contributory negligence is the harshest rule: if the plaintiff contributed even 1 percent to their own harm, they recover nothing. This common-law doctrine survives in only a handful of jurisdictions in 2026 — Alabama, Maryland, North Carolina, Virginia, and the District of Columbia.
Comparative negligence is the modern majority rule. The plaintiff's recovery is reduced by their percentage of fault. Three variants exist:
| Variant | How recovery works |
|---|---|
| Pure comparative | Plaintiff recovers their damages minus their fault %, even if 99% at fault |
| Modified — 50% bar | Plaintiff recovers only if their fault is less than 50% |
| Modified — 51% bar | Plaintiff recovers only if their fault is 50% or less (barred at 51%) |
Worked example: A plaintiff with $100,000 in damages is found 30% at fault. Under any comparative system, recovery = $100,000 x (1 - 0.30) = $70,000. Under contributory negligence, the same plaintiff recovers $0.
Assumption of risk bars recovery when the plaintiff voluntarily and knowingly accepted a known danger — for example, a spectator struck by a foul ball at a baseball game who understood that risk on entering the park.
A plaintiff with $80,000 in proven damages is found 40% at fault in a state using a modified comparative negligence (50% bar) rule. How much does the plaintiff recover?
Categories of Damages
When liability is established, the court awards damages. The exam groups them into three categories.
- Special (economic) damages — measurable out-of-pocket losses: medical bills, lost wages, repair or replacement costs, future earnings. These have a receipt or a calculation behind them.
- General (non-economic) damages — intangible harm with no fixed price tag: pain and suffering, disfigurement, loss of consortium, emotional distress.
- Punitive (exemplary) damages — awarded to punish willful, wanton, or grossly reckless conduct and to deter others, over and above compensatory damages.
Exam alert: Punitive damages are uninsurable in many states as a matter of public policy — allowing insurance to pay them would defeat their purpose of punishing the wrongdoer. Where insurable, they are often excluded by endorsement. Special and general damages, by contrast, are the compensatory sums liability policies are designed to pay.
Compensatory vs. Punitive
Special plus general damages together are called compensatory damages — they make the victim whole. Punitive damages are not compensatory; they are a penalty. This distinction explains why a $250,000 liability limit comfortably pays a compensatory award but may leave the insured personally exposed for any punitive add-on.
Strict (Absolute) Liability
Strict liability — also called absolute liability — imposes responsibility without any proof of fault or negligence. The plaintiff need not prove DBCD; merely showing that the activity caused harm is enough. Courts apply it to three main situations:
- Abnormally dangerous (ultrahazardous) activities — blasting with explosives, storing toxic chemicals, keeping wild animals.
- Defective products — a manufacturer is strictly liable for an unreasonably dangerous defect that injures a user (products-liability law).
- Statutory strict liability — certain statutes, such as dog-bite statutes and dramshop (liquor-liability) laws, impose liability regardless of care.
Because fault is irrelevant, the usual negligence defenses are limited; this is why product manufacturers and contractors carry high CGL and umbrella limits.
Vicarious Liability — Responsibility for Another's Acts
Vicarious liability imputes one party's negligence to another party because of the relationship between them, even though the second party did nothing wrong personally.
| Doctrine / relationship | Who becomes liable |
|---|---|
| Respondeat superior (employer-employee) | Employer for employee acts within the scope of employment |
| Family purpose / vehicle owner | Auto owner for a permissive user's negligence |
| Parental liability | Parents for certain acts of minor children (often capped by statute) |
| Principal-agent | Principal for the authorized acts of an agent |
Trap: Respondeat superior reaches only acts within the scope of employment. An employee on a purely personal errand (a "frolic and detour") generally takes the employer outside vicarious liability. This is why CGL policies carefully define who is an insured and why employers buy high limits and umbrellas — a single employee's on-the-job negligence can expose the entire enterprise.
A demolition company uses explosives that crack a neighbor's foundation despite taking every reasonable precaution. On what basis is the company most likely liable?
A delivery driver negligently injures a pedestrian while making a company delivery. The injured party sues the employer. Which doctrine allows the employer to be held liable?
Assumption of Risk and the Last Clear Chance
Assumption of risk completely bars recovery when a plaintiff voluntarily and knowingly confronts a danger and accepts the consequences. It has two forms: express assumption (signing a waiver before skydiving or joining a gym) and implied assumption (a hockey spectator who chooses a seat near the ice). The defense fails if the risk was hidden, the consent was not truly voluntary, or a statute forbids the waiver.
Under the old contributory-negligence regime, courts softened the harsh all-or-nothing rule with the last clear chance doctrine: a negligent plaintiff could still recover if the defendant had the final, realistic opportunity to avoid the harm and failed to take it. Most comparative-fault states have folded this idea into the percentage allocation of fault, but the exam may still reference it as a contributory-negligence escape hatch.
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 must then seek contribution from the others. A defendant only 20 percent at fault can be forced to pay 100 percent of the award if the co-defendants are insolvent. Many states have modified or abolished pure joint-and-several liability, but it remains a reason businesses buy high CGL and umbrella limits: a minor participant in a multi-party accident can shoulder the whole verdict.
Exam tie-in: Damages categories interact with these rules. A defendant held jointly and severally liable for $1,000,000 in compensatory damages must pay it even at low fault, but a separate punitive award against that defendant is usually that defendant's alone and, in many states, uninsurable — leaving the insured personally exposed beyond the policy.
