8.2 Defenses, Damages, and Vicarious Liability

Defenses to a Negligence Claim

Even when negligence is alleged, the defendant can reduce or eliminate liability through recognized defenses. The exam expects you to know how each treats a plaintiff who shares fault.

Worked Example — Comparative Negligence

A jury awards $100,000 and finds the plaintiff 30% at fault.

• Pure comparative: $100,000 × (1 − 0.30) = $70,000 recovered.
• Modified 51% rule: plaintiff is below 51%, so recovers the same $70,000.
• Contributory negligence state: plaintiff recovers $0 because of any fault.

If the plaintiff were instead 60% at fault, the modified 51% rule bars recovery entirely, while pure comparative would still pay $40,000.

Categories of Damages

Damages are the dollars a liable party owes. The exam tests the three categories and which ones liability policies pay.

Compensatory Damages

Meant to make the plaintiff "whole." Two subtypes:

• Special (economic) damages — measurable: medical bills, lost wages, repair costs.
• General (non-economic) damages — intangible: pain and suffering, disfigurement, loss of consortium.

Punitive (Exemplary) Damages

Awarded to punish willful, wanton, or grossly negligent conduct. Many states bar insuring punitive damages as against public policy, so coverage varies — a common exam trap.

Vicarious Liability

Vicarious liability holds one party responsible for the negligent acts of another due to a relationship, even when the responsible party did nothing wrong.

• Respondeat superior — an employer is liable for employee torts committed within the scope of employment.
• Parental liability — parents liable for certain acts of minor children (often capped by statute).
• Auto agency / family purpose — a vehicle owner liable for a permissive user's negligence.

Worked Example — Vicarious Exposure

A delivery driver, on the clock, runs a stop sign and injures a pedestrian. Under respondeat superior, the employer is vicariously liable. The ISO CGL form covers the employer's vicarious exposure; the Business Auto Coverage Form CA 00 01 would respond to the auto-specific bodily injury claim.

Comparative vs. Contributory Negligence — The Three Systems

The exam contrasts three fault-allocation rules and how each affects recovery:

• Pure contributory negligence — a plaintiff even 1% at fault recovers nothing. A harsh, minority rule.
• Pure comparative negligence — the plaintiff recovers their damages reduced by their own percentage of fault, even if 90% at fault (recovers 10%).
• Modified comparative negligence — the plaintiff recovers reduced damages only if their fault is below a threshold (commonly 50% or 51%); at or above it they recover nothing.

A stem giving the plaintiff's fault percentage and the damages is testing which system applies and the resulting recovery.

Worked Example — Modified Comparative (51% Bar)

Damages are $200,000; the plaintiff is 40% at fault in a 51% modified-comparative state. Because 40% is below the 51% bar, the plaintiff recovers $200,000 × (1 − 0.40) = $120,000. Had the plaintiff been 55% at fault, recovery would be $0.

Other 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 may recover if the defendant had the last opportunity to avoid the harm.
• Statute of limitations — suit filed after the limitations period is barred.
• Immunities — governmental, charitable, or intra-family immunity may bar a claim.

Vicarious Liability in Depth

Vicarious liability holds one party responsible for another's torts because of their relationship: employer for employee (respondeat superior, within the scope of employment), principal for agent, parent for child under family-purpose or statutory rules, and vehicle owner for a permissive driver under owner-liability statutes. The actor remains personally liable; vicarious liability simply adds the deeper-pocket defendant. This is why employers carry CGL and auto liability for acts of employees, and why additional insured endorsements exist to extend coverage to parties exposed vicariously.

Joint and Several Liability and Contribution

When two or more defendants cause an 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 for their shares. This is why a deep-pocket defendant only 20% at fault can be forced to pay 100% and chase reimbursement — a reason businesses carry adequate liability limits and umbrellas. Many states have modified the rule so that a defendant below a fault threshold pays only its proportional share, especially for non-economic damages.

Statutory and Contractual Liability

Beyond negligence and intentional torts, liability arises by statute (dram-shop laws holding alcohol servers liable, environmental statutes) and by contract (a hold-harmless or indemnification agreement in a lease or construction contract). The CGL covers contractual liability only for an insured contract; liability the insured assumes beyond that may be uninsured. A stem describing a tenant who agreed in a lease to indemnify the landlord is testing contractual (assumed) liability and whether the insured-contract exception applies.
