8.2 Defenses, Damages, and Vicarious Liability

Key Takeaways

  • Pure contributory negligence bars ALL recovery if the plaintiff is even 1% at fault (only AL, MD, NC, VA, and DC).
  • Pure comparative reduces recovery by the plaintiff's fault at any percentage; modified comparative bars recovery at the 50% or 51% threshold.
  • Special damages are measurable economic losses; general damages cover pain and suffering; punitive damages punish willful conduct and are often uninsurable.
  • Vicarious liability (respondeat superior) imputes an employee's negligence to the employer when acts occur within the scope of employment.
  • Read modified-comparative wording carefully: a 50% bar and a 51% bar produce different outcomes at exactly 50-51% plaintiff fault.

Defenses to Negligence

Even where the four elements exist, a defendant may reduce or eliminate liability with an affirmative defense. The exam tests the difference between contributory and comparative systems — and the precise thresholds.

DefenseEffect
Pure contributory negligenceIf the plaintiff is even 1% at fault, recovery is completely barred. Only a handful of jurisdictions (Alabama, Maryland, North Carolina, Virginia, and the District of Columbia) still apply it.
Pure comparative negligenceRecovery is reduced by the plaintiff's fault percentage; the plaintiff can recover even if 99% at fault.
Modified comparative negligenceRecovery is reduced by fault but barred once the plaintiff reaches the 50% or 51% threshold (varies by state).
Assumption of riskPlaintiff knew of, appreciated, and voluntarily accepted a specific danger.
Last clear chancePlaintiff may still recover if the defendant had the final opportunity to avoid the harm.

Worked Example — Comparative Fault Math

A plaintiff suffers $100,000 in damages. Apply each system when the plaintiff is found 40% at fault:

  • Pure contributory: $0 — any plaintiff fault bars recovery.
  • Pure comparative: $100,000 × (1 − 0.40) = $60,000.
  • Modified (51% bar): plaintiff is below the 51% threshold, so still recovers $60,000.

Now change the plaintiff's fault to 51% under a 50% bar state: recovery is $0 because the plaintiff has reached or exceeded the bar. Under a 51% bar state at exactly 51% fault, recovery is also $0. The exam loves the one-point difference — read whether the rule is "50% or more" versus "51% or more."

The distinction matters most at the boundary. In a 50% bar state, a plaintiff who is exactly 50% at fault recovers nothing. In a 51% bar state, that same 50%-at-fault plaintiff recovers half ($50,000 on a $100,000 loss), and is barred only at 51% or higher. When a question gives both the loss amount and a fault percentage near the threshold, identify the bar type first, then apply the reduction only if the plaintiff is below it.

Types of Damages

  • Compensatory — Special damages: measurable economic losses (medical bills, lost wages, repair costs).
  • Compensatory — General damages: non-economic losses (pain and suffering, disfigurement, loss of consortium).
  • Punitive (exemplary) damages: punish willful, wanton, or malicious conduct. Many liability policies and several states exclude or bar coverage for punitive damages as a matter of public policy.

Vicarious Liability

Vicarious liability imputes one party's negligence to another because of their relationship — even though the second party did nothing wrong personally. Under respondeat superior, an employer is liable for an employee's negligent acts committed within the scope of employment. Parents may be vicariously liable for minor children, and a vehicle owner may be liable for a permissive driver. This is why CGL and auto forms extend coverage to employees and permissive users as insureds.

A key limit: respondeat superior reaches only acts within the scope of employment. An employee running a personal errand on a "frolic of his own" generally takes the employer outside vicarious liability. Independent contractors are usually not the principal's responsibility either, except for non-delegable duties or inherently dangerous work. These boundaries shape how CGL endorsements such as additional-insured and hired/non-owned auto coverage are written, and explain why businesses require certificates of insurance from contractors.

A claims tip on damages: special damages are documented with receipts and records, so they are relatively fixed, while general damages (pain and suffering) are negotiated and drive most of the variability in liability settlements. Adjusters sometimes estimate general damages as a multiple of specials, though this is custom, not law. Because punitive damages punish conduct rather than compensate loss, insureds facing punitive exposure may need separate, narrowly worded coverage where state law even permits it; the standard CGL does not affirmatively grant it.

Defenses to Negligence

Defendants reduce or defeat liability through recognized defenses, which the exam ties to specific state rules:

DefenseEffect
Contributory negligenceClaimant who is even 1% at fault recovers nothing (a few states)
Pure comparative negligenceRecovery reduced by the claimant's % of fault (recover even at 99% fault)
Modified comparative negligenceRecover only if fault is below 50%/51%
Assumption of riskKnowingly accepting a danger bars recovery
Last clear chanceClaimant recovers if defendant had the final opportunity to avoid harm

Washington follows pure comparative negligence, so a claimant's award is reduced by their own percentage of fault but is not eliminated.

Categories of Damages

Damage typePurposeInsurable?
Special (economic) compensatoryQuantifiable - medical bills, lost wages, repair costsYes
General (non-economic) compensatoryPain and suffering, disfigurementYes
Punitive (exemplary)Punish/deter egregious conductOften uninsurable by public policy

Vicarious Liability

Vicarious liability holds one party responsible for another's negligence due to a relationship. Examples: an employer for an employee acting within the scope of employment (respondeat superior); a vehicle owner for a permissive driver; a parent for a child in some statutes. Liability policies often extend to these imputed exposures.

Worked Comparative Example

A claimant suffers $100,000 in damages but is found 30% at fault in a pure comparative-negligence state like Washington. Recovery is reduced by 30%: $100,000 x (1 - 0.30) = $70,000. In a strict contributory-negligence state, the same 30% fault would bar all recovery - a stark contrast the exam uses to test which rule applies. Punitive damages, if awarded, would typically fall outside the liability policy's coverage as uninsurable.
