8.1 Negligence, Torts, and Legal Liability

Why Liability Concepts Dominate the Casualty Exam

Liability insurance pays sums the insured becomes legally obligated to pay as damages because of bodily injury (BI), property damage (PD), or personal and advertising injury suffered by a third party. Every casualty form you study — the ISO Personal Auto Policy (PP 00 01), the Homeowners Section II (HO 00 03), and the Commercial General Liability Coverage Form (CG 00 01) — is built on one legal engine: the law of torts. If you understand how legal liability arises, the policy language stops being arbitrary.

A tort is a civil wrong (other than breach of contract) for which the law allows the injured party to recover damages. Torts fall into three families, and the exam expects you to sort any scenario into the correct box.

The Three Categories of Torts

The key exam trap: standard liability policies cover unintentional harm. The CGL and PAP both exclude "expected or intended" injury. A bar owner who deliberately punches a customer has committed an intentional tort — battery — and the insurer can deny the BI claim.

The Four Elements of Negligence (DBCD)

Nearly every liability claim is a negligence claim, and to recover, the plaintiff must prove all four elements. Memorize them as DBCD:

1. Duty — a legal obligation to exercise a reasonable standard of care toward the claimant. The benchmark is the reasonably prudent person under similar circumstances.
2. Breach — failure to meet that standard of care (an act or an omission).
3. Causation — the breach was the proximate cause of the injury (an unbroken chain, with no superseding event).
4. Damages — actual, measurable harm (medical bills, lost wages, property repair). Without provable damages, there is no negligence claim, no matter how careless the conduct.

Proximate Cause and Standard of Care

Proximate cause is the cause that, in a natural and continuous sequence, produces the injury. A defendant's careless act that is too remote — broken by an unforeseeable intervening cause — does not satisfy this element.

The standard of care can rise above the ordinary prudent-person test. Professionals (physicians, attorneys, agents) are held to the standard of a reasonable practitioner in their field — the basis of professional liability / errors & omissions claims. Property owners owe higher duties to invitees (business customers) than to licensees (social guests), and the lowest duty to trespassers.

Negligence Per Se and Res Ipsa Loquitur

Two doctrines change how a plaintiff proves breach, and both appear on the national exam:

• Negligence per se — when a defendant violates a safety statute (running a red light, ignoring a building code) and the violation causes the harm the statute was designed to prevent, breach of duty is presumed.
• Res ipsa loquitur ("the thing speaks for itself") — applies when the injury would not ordinarily happen without negligence, the instrumentality was in the defendant's exclusive control, and the plaintiff did not contribute. A surgical sponge left inside a patient is the classic example; the burden shifts to the defendant to disprove negligence.

Both doctrines help a plaintiff who cannot directly prove the breach element, and both raise an insurer's exposure because liability is easier to establish.

Absolute (Strict) Liability

Absolute liability — also called strict liability — imposes responsibility without regard to fault or negligence. The plaintiff need only show that the activity occurred and caused harm. It applies to ultra-hazardous activities and certain statutory areas:

• Abnormally dangerous activities: blasting with explosives, storing toxic chemicals, transporting hazardous materials.
• Keeping wild or dangerous animals (and, by statute in many states, dog-bite liability).
• Product liability under strict products doctrine: a manufacturer of a defective and unreasonably dangerous product is liable to the user even with no proof of carelessness. This drives the products-completed operations exposure on the CGL.

Unlike intentional torts, strict liability is insurable — the CGL's products-completed operations hazard exists precisely to fund these claims.

Compensatory vs. Punitive — and Why Fault Matters to Insurers

Liability claims resolve into damages, and the insurer's promise under Coverage A is to pay sums the insured is legally obligated to pay. Two consequences flow from the negligence framework:

1. Fault drives the dollars. Because most awards are reduced by the claimant's own share of fault (the comparative-negligence doctrines covered later), establishing the claimant's contribution directly lowers the insurer's payout.
2. Not all damages are insurable. Compensatory damages (special + general) are the core of coverage, but punitive damages — intended to punish, not compensate — are barred from insurance in many states as a matter of public policy.

The agent's takeaway: the cleaner the liability picture (clear duty, obvious breach, direct causation, documented damages), the more likely the claim is paid in full up to the policy limit, and the harder it is to apply a defense.
