8.2 Defenses, Damages, and Vicarious Liability

Once a plaintiff alleges negligence, the defense raises legal defenses that can reduce or eliminate liability — and therefore the insurer's payment. The exam tests three negligence-allocation systems plus a handful of named defenses.

Comparative vs. Contributory Negligence

Most states allocate fault between the parties. Know all three rules and their dollar effect:

Worked example: A jury awards $200,000 and finds the plaintiff 40% at fault. Under pure comparative negligence the plaintiff collects $200,000 × (1 − 0.40) = $120,000. Under pure contributory negligence (a minority of states) the plaintiff's 40% fault bars the entire claim — $0. The same facts, wildly different payouts; read the question stem for which system applies.

Named Defenses

• Assumption of risk — the plaintiff knowingly and voluntarily accepted a known danger (a spectator hit by a foul ball).
• Last clear chance — even a contributorily negligent plaintiff recovers if the defendant had the final opportunity to avoid harm.
• Statute of limitations — the claim was filed too late.
• Intervening cause — a superseding event broke the chain of proximate causation.

Types of Damages

Damages are the money awarded. Liability policies cover compensatory damages but generally not punitive damages (and many states bar insuring them as against public policy).

The CGL pays compensatory damages for bodily injury and property damage. A jury award might read "$50,000 medical and lost wages (special) + $75,000 pain and suffering (general) + $200,000 punitive." The policy responds to the $125,000 compensatory total but typically not the punitive $200,000.

Vicarious Liability

Vicarious liability holds one party responsible for another's tort because of their relationship — fault is imputed without the principal personally acting wrongly. Tested examples:

• Employer–employee (respondeat superior): an employer is liable for an employee's negligence committed within the scope of employment. The CGL covers the employer here.
• Principal–agent: a producer's negligent act can be imputed to the carrier.
• Parent–child / vehicle owner–permissive user: many states impute the driver's negligence to the owner who lent the car, which is why the PAP extends liability to permissive users.

A key limit: vicarious liability for an employee usually does not extend to acts outside the scope of employment or to independent contractors, whose negligence the hiring party generally does not answer for.

Joint and Several Liability

When two or more parties cause a single indivisible harm, joint and several liability lets the plaintiff collect the entire judgment from any one defendant, regardless of that defendant's share of fault. The paying defendant then seeks contribution from the others.

Worked example: A $1,000,000 judgment is split 90% to a nearly bankrupt contractor and 10% to a well-insured property owner. Under joint and several liability the plaintiff can collect the full $1,000,000 from the property owner (the 'deep pocket'), who must then chase the contractor for the $900,000. This is why a minor-fault insured can face a major-limit demand, and why umbrella/excess liability matters.

How Defenses Reach the Insurer's Wallet

Every defense that reduces the plaintiff's recovery reduces the insurer's payment. The carrier's duty to defend is broader than its duty to indemnify: the insurer must defend any suit that potentially falls within coverage, even groundless ones, and defense costs are usually paid in addition to the policy limits (outside the limits) on the CGL. Once the limit is paid out in settlement or judgment, the duty to defend ends.

Damages Mitigation and Collateral Sources

Two more concepts surface as distractors. The duty to mitigate requires an injured plaintiff to take reasonable steps to limit their own damages — a plaintiff who refuses reasonable medical care cannot recover for the worsened injury.

The collateral source rule (in many states) bars the defendant from reducing damages just because the plaintiff was reimbursed from another source such as health insurance, though subrogation may then let that other insurer recover.

For the producer, the takeaway is that the net check an insurer writes turns on the fault-allocation system, the damage categories, the duty to defend, and these adjusting doctrines — not on the headline jury number alone.
