8.2 Defenses, Damages, and Vicarious Liability

Common-Law Defenses to Negligence

Even when negligence appears established, the defendant may reduce or escape liability with a recognized defense. Exam questions hinge on which defense a state follows:

• Contributory negligence — if the plaintiff contributed at all to the harm, recovery is BARRED entirely. A harsh, minority rule (e.g., Virginia, Maryland, Alabama, North Carolina, D.C.).
• Comparative negligence (pure) — damages are reduced by the plaintiff's percentage of fault; a 90%-at-fault plaintiff still recovers 10%.
• Comparative negligence (modified, 50%/51% rule) — the plaintiff recovers only if their fault is below the threshold; the majority approach.
• Assumption of risk — the plaintiff knowingly and voluntarily accepted a known danger.
• Last clear chance — a doctrine that lets a negligent plaintiff still recover if the defendant had the final opportunity to avoid harm.

Worked Example — Comparative Negligence

A court awards $100,000 in damages and finds the plaintiff 30% at fault.

• Pure comparative: recovery = $100,000 x (1 - 0.30) = $70,000.
• Modified 50% rule (must be UNDER 50%): plaintiff is 30% < 50%, so recovers $70,000.
• Contributory negligence state: any plaintiff fault bars recovery — plaintiff recovers $0.

The same facts produce wildly different outcomes by state — a classic exam trap. If the plaintiff were 55% at fault: pure = $45,000; modified 50% = $0; contributory = $0.

Categories of Damages

Liability policies pay compensatory damages, which split into two parts. Punitive damages are a separate, often-excluded category:

Special + general = compensatory. Many states (and policy provisions) bar or limit insurance for punitive damages on public-policy grounds, so do not assume the liability limit covers them.

Vicarious Liability

Vicarious liability holds one party responsible for the negligent acts of another because of their relationship. The doctrine respondeat superior ("let the master answer") makes an employer liable for an employee's torts committed within the scope of employment.

Other examples: a parent liable for a minor child's acts under family-purpose statutes; a vehicle owner liable for a permitted driver. The CGL covers the named insured's vicarious liability for employees acting in the business; the Personal Auto Policy (PP 00 01) extends Part A liability to permissive users via the omnibus clause.

Assumption of Risk and Last Clear Chance

Beyond comparative/contributory negligence, two doctrines appear. Assumption of risk bars recovery when a plaintiff voluntarily and knowingly accepted a danger (a spectator hit by a foul ball). Last clear chance lets a contributorily negligent plaintiff still recover if the defendant had the final opportunity to avoid the harm and failed — a common rebuttal in pure-contributory states.

Comparative Negligence Variants

Damages and Vicarious Liability Recap

Compensatory damages split into special (measurable: medical bills, lost wages) and general (pain and suffering, disfigurement). Punitive damages punish egregious conduct and are uninsurable in many states as a matter of public policy — a tested point. Vicarious liability holds one party responsible for another's torts: employers for employees acting in the scope of employment (respondeat superior), vehicle owners for permitted drivers under some state statutes, and parents for certain acts of minors. Liability policies extend to these imputed exposures, which is why "who is an insured" definitions are so important.

Applying Defenses and Damages on the Exam

Liability questions frequently turn on which negligence defense the jurisdiction follows, because the same facts produce opposite outcomes. Under pure contributory negligence any plaintiff fault is a complete bar, so a one-percent-at-fault plaintiff recovers nothing, while pure comparative negligence reduces recovery by the plaintiff's share no matter how large, and the modified comparative systems bar recovery once the plaintiff reaches fifty or fifty-one percent. Layer on assumption of risk and last clear chance, and you can resolve almost any fault-allocation stem.

On damages, separate special damages, which are measurable economic losses such as medical bills and lost wages, from general damages for pain and suffering, and remember that punitive damages punish egregious conduct and are uninsurable in many states. Vicarious liability then extends responsibility to employers, vehicle owners, and parents, which is why the policy's definition of who is an insured matters so much.

Because the same accident yields different recoveries under different fault rules, always confirm the jurisdiction's negligence system before computing a plaintiff's award, and confirm whether punitive damages are insurable in that state before assuming the policy will pay them.
