8.2 Defenses, Damages, and Vicarious Liability

Defenses Against a Negligence Claim

A defendant can defeat or shrink liability with recognized defenses:

• Contributory negligence - in a few states, if the plaintiff is even 1% at fault, recovery is barred entirely.
• Comparative negligence - most states reduce the award by the plaintiff's percentage of fault (pure or modified 50%/51% rules).
• Assumption of risk - the plaintiff knowingly accepted a known danger.
• Statute of limitations - the suit was filed too late.
• Intervening cause - a new event broke the chain of proximate cause.

Worked Example: Comparative Negligence

Under pure comparative negligence, a plaintiff with total damages of $100,000 who is found 30% at fault recovers:

$100,000 x (1 - 0.30) = $70,000

Under a modified 51% rule, a plaintiff who is 55% at fault recovers $0, because their fault exceeds the threshold. Under contributory negligence, that same plaintiff also recovers $0 even at 5% fault.

Exam trap: contributory negligence is the harshest doctrine (all-or-nothing); comparative negligence is the proportional, more common standard.

Mapping fault doctrines to a single fact pattern

A clean way to lock in the defenses is to run one fact pattern through each rule. A pedestrian who is 30% responsible for a $100,000 injury recovers: $100,000 under no defense; $70,000 under pure comparative negligence; $0 under contributory negligence (even 1% bars recovery); and $70,000 under a 50%/51% modified rule (because 30% is below the bar). Maryland's pure-contributory rule is the harshest, which is why last clear chance exists to soften it - if the defendant had the final realistic opportunity to avoid the harm, the plaintiff's own negligence is excused.

Why vicarious liability drives coverage design

Vicarious liability - one party answerable for another's negligence - is the reason liability forms extend to people beyond the named insured. Respondeat superior makes an employer liable for an employee acting within the scope of employment, so the CGL and commercial auto forms automatically make employees and permissive users insureds. Statutes can extend this to vehicle owners for permissive users and parents for minors.

The exam trap: an employee acting outside the scope of employment (a frolic of his own) breaks the employer's vicarious liability, and the auto or CGL may then decline because the act was personal, not business.

The Last Clear Chance Doctrine

In contributory-negligence states, the harsh all-or-nothing rule is softened by the last clear chance doctrine. Even if the plaintiff was negligent, the defendant remains liable if the defendant had the final opportunity to avoid the harm and failed to act.

Example: a pedestrian jaywalks (negligent), but a driver who sees the pedestrian with ample time to brake and does not is liable under last clear chance. Exam trap: last clear chance is a plaintiff's rebuttal to a contributory-negligence defense, not a separate cause of action, and it has little role in comparative-fault states where fault is already apportioned.

Absolute (Strict) Liability in Practice

Strict (absolute) liability imposes liability without proof of negligence. The plaintiff need not show breach of a duty of care; the activity or product itself triggers responsibility.

Common strict-liability situations:

• Ultrahazardous activities - blasting, storing explosives, keeping wild animals.
• Defective products - a manufacturer is liable for a dangerous defect regardless of care taken.
• Statutory dram-shop and animal-bite laws in some states.

Liability insurance still responds to strict-liability claims because the insured is legally obligated to pay; fault is simply not part of the analysis. Products-completed operations coverage on the CGL is the usual home for product strict-liability claims.

Damages: Compensatory and Punitive

Courts award two broad classes of damages:

Special damages are also called specials and are easy to quantify with receipts. General damages require a judgment call. Punitive damages are not insurable in many states as a matter of public policy, so coverage varies by jurisdiction.

How Damages Map to Policy Limits

Damages determine how much a liability policy pays. Special and general compensatory damages both count against the policy's per-occurrence limit. Punitive damages, where insurable, may exhaust limits quickly because they are untethered to actual loss.

Consider a single auto-liability occurrence with split limits of 100/300/50 (in thousands):

• $100,000 maximum bodily injury per person
• $300,000 maximum bodily injury per accident
• $50,000 maximum property damage per accident

If three claimants suffer $80,000, $120,000, and $150,000 in BI, the per-person cap limits the second to $100,000 and the third to $100,000, and the $300,000 per-accident cap then governs the total payout.

Vicarious Liability

Vicarious liability makes one party legally responsible for the negligent acts of another, even when the first party did nothing wrong. The classic case is respondeat superior - an employer is liable for an employee's negligence committed within the scope of employment.

Other examples tested:

• A parent liable for a minor child's acts under family-purpose or statute.
• A vehicle owner liable for a permissive user under a state's permissive-use law.
• A principal liable for an agent's conduct.

Bold rule: vicarious liability is why employers buy liability coverage and why CGL and commercial auto forms extend to employees and permissive users as insureds.
