8.1 Negligence, Torts, and Legal Liability
Key Takeaways
- Liability insurance is THIRD-PARTY coverage — it pays the injured claimant when the insured is legally liable, never the insured's own loss.
- A tort is a civil wrong; the three classes are intentional torts, negligence, and absolute (strict) liability.
- Negligence requires ALL FOUR elements: Duty, Breach, Proximate Causation, and Damages (D-B-C-D).
- Carelessness without actual damages is not a compensable tort; proximate cause must be an unbroken chain.
- Intentional torts are excluded by the 'expected or intended' exclusion in the CGL (CG 00 01) and Homeowners Section II (HO 00 03).
Liability Insurance Is Third-Party Coverage
Liability insurance is third-party coverage: it pays others when YOU are legally liable for their bodily injury or property damage. The three parties are the first party (the insured), the second party (the insurer), and the third party (the injured claimant). Liability coverage never pays for the insured's own losses — that is what property (first-party) coverage does.
Legal liability arises three ways: from a tort (a civil wrong), from a contract (an assumed obligation), or by statute (such as workers' compensation laws). Most liability claims insurers handle are tort claims, and the overwhelming majority of those are based on negligence.
Categories of Torts
A tort is a civil wrong (other than breach of contract) for which the law allows a remedy in money damages. Torts fall into three groups:
- Intentional torts — deliberate acts: assault, battery, libel, slander, false arrest. Generally EXCLUDED by the liability "expected or intended" exclusion.
- Negligence (unintentional torts) — failure to use reasonable care. This is the basis of most insured claims.
- Absolute (strict) liability — liability regardless of fault, imposed for inherently dangerous activities (blasting, keeping wild animals) and most product-defect claims.
The ISO Commercial General Liability (CGL) Coverage Form CG 00 01 04 13 and the personal Homeowners HO-3 (HO 00 03 10 22) Section II both respond to negligence-based claims; the intentional-injury exclusion strips out deliberate harm.
The Four Elements of Negligence
To win a negligence suit the claimant (plaintiff) must prove ALL FOUR elements. If even one fails, there is no negligence:
| # | Element | What the plaintiff must show |
|---|---|---|
| 1 | Duty | The defendant owed a legal duty of care (the "reasonable person" standard). |
| 2 | Breach | The defendant breached that duty (act or omission). |
| 3 | Causation | The breach was the proximate cause — an unbroken chain — of the harm. |
| 4 | Damages | The plaintiff suffered actual, measurable injury or loss. |
Memory hook: D-B-C-D (Duty, Breach, Causation, Damages). A common exam trap: a defendant can be careless yet NOT liable if there are no actual damages — carelessness alone is not a tort.
Proximate Cause and the Reasonable Person
Proximate cause is the direct, uninterrupted cause that produces the injury; without it, the injury would not have occurred. An intervening cause can break the chain and relieve the defendant of liability.
The standard of care is what a reasonable, prudent person would do under the same circumstances. Professionals (doctors, accountants, agents) are held to the higher standard of others in their profession — the basis for malpractice and errors & omissions (E&O) claims.
Negligence Per Se and Res Ipsa Loquitur
Two doctrines shift how negligence is proven. Negligence per se treats violation of a safety statute (running a red light, building-code breach) as automatic proof of the duty-and-breach elements when the plaintiff is in the class the law protects. Res ipsa loquitur ("the thing speaks for itself") lets a jury infer negligence from the very nature of an accident that ordinarily would not happen without someone's carelessness, even without direct evidence — the classic example is a surgical instrument left in a patient.
Degrees of Wrongdoing
| Conduct | Definition | Liability consequence |
|---|---|---|
| Ordinary negligence | Failure to use reasonable care | Compensatory damages |
| Gross negligence | Reckless disregard for others' safety | May support punitive damages |
| Willful/intentional tort | Deliberate harm | Punitive damages; often excluded by liability policies |
| Strict liability | Liability without fault (abnormally dangerous activity, defective product) | Applies regardless of care taken |
Why the Elements Matter for Coverage
Liability insurance responds to the insured's legal obligation to pay damages for bodily injury or property damage caused by negligence. If any element — duty, breach, causation, damages — is missing, there is no legal liability and thus nothing for the policy to indemnify, even though the insurer may still owe a duty to defend a groundless suit. The duty to defend is broader than the duty to indemnify: the insurer must defend any suit that potentially falls within coverage.
From Negligence to a Covered Claim
Liability coverage only responds when the insured has a legal obligation to pay damages, so every fact pattern reduces to whether the four elements of negligence are present. Walk them in order: did the defendant owe a duty of care, did the conduct breach the reasonable-person standard, was the breach the actual and proximate cause of the harm, and were there actual damages. If any element is missing there is no legal liability and the policy owes no indemnity, although the insurer may still owe a defense because the duty to defend is triggered by allegations that merely fall potentially within coverage.
The exam also tests the gradations of fault, since ordinary negligence supports compensatory damages while gross negligence or willful conduct can support punitive damages that many policies and many states will not insure. Recognizing strict-liability contexts, where fault is irrelevant, completes the analysis.
A homeowner leaves a garden hose stretched across a public sidewalk. A jogger trips, falls, and breaks her wrist. The jogger sues. Which negligence element is satisfied by the broken wrist?
