8.1 Negligence, Torts, and Legal Liability

Why Liability Insurance Exists

Liability insurance pays sums the insured becomes legally obligated to pay as damages because of bodily injury or property damage to a third party. The key phrase is legally obligated: if the insured is not legally responsible, the insurer owes nothing in damages. Establishing legal liability is therefore the gateway to every casualty claim, and the casualty half of the Property and Casualty (P&C) exam tests these foundations heavily.

First-Party vs. Third-Party

Liability is always third-party coverage — it protects the people the insured has harmed, not the insured's own property.

Trap: If a question describes the insurer paying the named insured's own loss, that is property/first-party coverage — never liability.

The Four Elements of Negligence

Negligence is the failure to exercise the degree of care a reasonably prudent person would exercise under the same circumstances. To recover on a negligence theory, the claimant must prove all four of these elements — missing even one defeats the claim:

1. Duty — a legal obligation to use reasonable care toward the claimant (a driver owes a duty to other motorists).
2. Breach — failure to meet that standard of care (texting while driving).
3. Proximate Cause — an unbroken causal chain linking the breach to the harm, with the harm reasonably foreseeable.
4. Damages — actual, measurable harm (medical bills, lost wages, property repair).

A handy mnemonic is D-B-C-D. If the insured breached a duty but no harm resulted, there is no negligence — and no liability claim.

Categories of Torts

A tort is a civil wrong (other than breach of contract) for which the law provides a remedy. Torts fall into three families:

• Negligence (unintentional torts) — careless conduct causing harm; the basis for the vast majority of liability claims.
• Intentional torts — deliberate acts such as assault, battery, libel, slander, false arrest, and trespass. Standard liability policies exclude expected or intended injury, so intentional torts are generally not covered.
• Absolute (strict) liability — liability imposed without fault because the activity is inherently dangerous (blasting, keeping wild animals) or by product-liability statute. The claimant need not prove negligence at all.

Trap: Strict liability does NOT require proof of negligence. Exam questions describing 'ultrahazardous' or 'inherently dangerous' activities point to absolute liability.

Statutory and Contractual Liability

Legal liability can also arise outside common-law negligence:

• Statutory liability is imposed by law — workers' compensation statutes, dram shop (liquor liability) laws, and financial-responsibility laws all create obligations regardless of fault.
• Contractual liability is liability the insured assumes under a contract, such as a hold-harmless agreement in a lease. The standard ISO Commercial General Liability (CGL) CG 00 01 form covers liability assumed under an 'insured contract' — a defined list including leases of premises, sidetrack agreements, and most written contracts — even though no tort occurred.

Trap: The CGL does NOT cover every contract. Liability assumed in a contract that is not an 'insured contract' falls under the contractual-liability exclusion.

The Standard of Care and the Reasonable Person

Negligence is measured against the 'reasonable person' standard — what an ordinarily prudent person would have done under the same circumstances. The standard adjusts for context: a professional (physician, accountant, attorney) is held to the higher standard of a reasonably competent member of that profession, which is why their failures are litigated as professional negligence (malpractice) rather than ordinary negligence.

Certain conduct establishes breach automatically:

• Negligence per se — violating a safety statute (running a red light) is treated as breach without further proof of unreasonableness.
• Res ipsa loquitur ('the thing speaks for itself') — when the harm could only have happened through someone's negligence and the instrument was in the defendant's exclusive control, breach is inferred (a surgical sponge left inside a patient).

Degrees of Care and Special Relationships

The degree of care owed can vary with the relationship between the parties. A common carrier (airline, bus line) owes its passengers a very high degree of care. A property owner historically owed different duties to invitees (business customers — highest duty), licensees (social guests), and trespassers (lowest duty), although many states have merged these categories into a single reasonable-care standard.

Gross negligence is an extreme departure from reasonable care — reckless disregard for others' safety — and can expose the insured to punitive damages. Willful and wanton conduct sits between gross negligence and an intentional tort. Because liability policies exclude expected or intended injury, the line between gross negligence (covered) and intentional harm (excluded) is heavily litigated.

Trap: Gross negligence is still negligence and is generally covered; an intentional tort is not. Read fact patterns carefully for whether the insured 'expected or intended' the harm.

Proximate Cause and Foreseeability

Proximate cause is the legal link between breach and harm. It is narrower than 'cause in fact': even if the breach was a factual cause, liability fails unless the harm was a reasonably foreseeable consequence. An unforeseeable intervening cause can break the chain and relieve the defendant — but a foreseeable intervening act (a rescuer being hurt) does not. Courts apply the 'but-for' test (would the harm have happened but for the breach?) with foreseeability to fix the boundary.

Trap: A superseding, unforeseeable intervening cause cuts off liability; a foreseeable one does not. Watch for 'an unrelated third party then did X' fact patterns testing this.
