8.2 Defenses, Damages, and Vicarious Liability
Key Takeaways
- Contributory negligence bars all recovery if the plaintiff is even 1% at fault; pure comparative reduces the award by the plaintiff's fault percentage.
- Modified comparative (50%/51% bar) lets the plaintiff recover only while their fault stays below the threshold.
- Compensatory damages = special (economic) + general (non-economic); punitive damages are often uninsurable by public policy.
- Defenses include assumption of risk, last clear chance, and the statute of limitations.
- Vicarious liability (respondeat superior) imputes liability to an employer for an employee's acts within the scope of employment.
Defenses Against a Negligence Claim
Even where negligence is shown, a defendant may reduce or defeat liability with a recognized defense. The exam expects you to distinguish the three damage-allocation rules, because the dollar outcome differs dramatically.
- Contributory negligence (a few states): if the plaintiff was even 1% at fault, recovery is barred entirely.
- Comparative negligence — pure: damages reduced by the plaintiff's percentage of fault; a 90%-at-fault plaintiff still recovers 10%.
- Comparative negligence — modified (50%/51% bar): plaintiff recovers only if their fault is below the threshold (e.g., not 50% or more).
Worked Allocation Example
A jury sets total damages at $100,000 and finds the plaintiff 30% at fault.
| Rule | Plaintiff recovers | Reasoning |
|---|---|---|
| Contributory negligence | $0 | Any plaintiff fault bars recovery |
| Pure comparative | $70,000 | $100,000 reduced by 30% |
| Modified comparative (51% bar) | $70,000 | Plaintiff under threshold, reduced by 30% |
If that same plaintiff were 60% at fault under the 51%-bar rule, recovery would be $0 — over the threshold. Under pure comparative, they would still collect $40,000.
Total damages are $200,000 and the plaintiff is found 25% at fault in a pure comparative negligence state. How much does the plaintiff recover?
Other Defenses
Assumption of risk — the plaintiff knowingly and voluntarily accepted a known danger (e.g., a spectator hit by a foul ball). Last clear chance — even a contributorily negligent plaintiff may recover if the defendant had the final opportunity to avoid harm. Statute of limitations — the suit was filed after the legal time limit expired. These are affirmative defenses the defendant must raise and prove.
Types of Damages
Liability policies pay "damages," but you must know which kinds are covered.
| Category | Subtype | Description | Typically covered? |
|---|---|---|---|
| Compensatory | Special | Measurable economic loss: medical bills, lost wages, repair costs | Yes |
| Compensatory | General | Non-economic: pain and suffering, disfigurement | Yes |
| Punitive | — | Punishes/deters egregious conduct | Often excluded or barred by state law |
The exam trap: punitive (exemplary) damages are frequently not insurable as a matter of public policy in many states. Special + general damages together make up compensatory damages.
An injured party is awarded $40,000 for medical bills and lost income, $25,000 for pain and suffering, and $50,000 to punish the defendant's gross misconduct. Which amount represents special (compensatory) damages?
Vicarious Liability
Vicarious liability holds one party responsible for the negligent acts of another based on their relationship — fault is imputed, not committed personally. The classic doctrine is respondeat superior ("let the master answer"): an employer is liable for an employee's negligence committed within the scope of employment. Other examples: a parent liable for a minor child's acts, or a vehicle owner liable for a permissive driver ("omnibus" insured under an auto policy). This is why CGL and BAP forms extend coverage to employees and permitted users as additional insureds.
Joint and Several Liability
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 then seeks contribution from the others. A "deep-pocket" defendant only 10% at fault could pay 100% and chase the rest. Many states have modified this with proportionate-share statutes, but the doctrine is still tested as the reason an insurer with a solvent insured may bear an outsized share.
Independent Contractors vs. Employees
Vicarious liability under respondeat superior reaches employees within the scope of employment but generally not independent contractors — the hirer does not control the contractor's methods. Exceptions: non-delegable duties and inherently dangerous work. This distinction drives whether a CGL (the hirer) or the contractor's own policy responds, and it is a common scenario question.
Attractive Nuisance
A special duty rule: a landowner can be liable to trespassing children injured by an artificial, alluring hazard (an unfenced pool, abandoned appliance) under the attractive-nuisance doctrine, even though adult trespassers would be owed almost no duty. Premises-liability questions test the different duties owed to invitees, licensees, and trespassers.
Comparative-Fault Outcomes in One Glance
| System | Plaintiff 30% at fault, $100k damages | Plaintiff 60% at fault |
|---|---|---|
| Contributory | $0 | $0 |
| Pure comparative | $70,000 | $40,000 |
| Modified (50% bar) | $70,000 | $0 (≥50%) |
| Modified (51% bar) | $70,000 | $0 (>50%) |
Colorado uses modified comparative with a 50% bar (C.R.S. 13-21-111): a plaintiff 50% or more at fault recovers nothing. Memorizing the difference between the 50% and 51% thresholds is a frequent multi-state trap.
Negligence Per Se and Strict Liability Recap
Negligence per se establishes breach automatically when a defendant violates a safety statute designed to protect the class of person harmed (an unfenced pool violating code). Strict liability removes the fault question entirely for ultrahazardous activities and defective products — the plaintiff need only prove the defect/activity and causation, not carelessness. Distinguishing fault-based negligence from no-fault strict liability is the core of product-liability questions.
Premises-Liability Duty Levels
A landowner owes different duties by visitor class: highest care to an invitee (business customer — duty to inspect and warn of/repair hazards), a moderate duty to a licensee (social guest — warn of known dangers), and the least to a trespasser (only refrain from willful harm), with the attractive-nuisance exception protecting child trespassers. Sorting a slip-and-fall plaintiff into the right class drives whether the occupier breached a duty — a common CGL/HO liability scenario.
Compensatory vs. Punitive Recap
Compensatory damages (special = economic; general = pain/suffering) make the plaintiff whole and are covered. Punitive (exemplary) damages punish egregious conduct and are frequently uninsurable as a matter of public policy in many states, including limits in Colorado. The exam's favorite damages trap is selecting punitive damages as a covered amount — usually wrong.
