Chapter 5: Fundamentals of Tort Law – Civil Wrongs in a Business Context

Tort law provides remedies for civil wrongs, distinct from contract and criminal law.

🎯 Learning Objectives

• Define a tort and distinguish it from a crime and a breach of contract.
• Identify the three main categories of torts: intentional torts, negligence, and strict liability.
• Understand the purpose of tort law: compensation, deterrence, and fairness.
• Analyze landmark cases that shaped tort law, including Donoghue v. Stevenson (negligence) and Rylands v. Fletcher (strict liability).
• Apply tort principles to common business scenarios (slip‑and‑fall, product liability, defamation).

📖 Introduction

While contract law governs voluntarily assumed obligations, tort law imposes duties that arise by operation of law. A tort is a civil wrong that causes harm to another, for which the law provides a remedy (usually monetary damages). Unlike crimes, which are prosecuted by the state, torts are private wrongs that the injured party pursues. Unlike breach of contract, tort duties are imposed regardless of any agreement. This chapter explores the foundations of tort liability, focusing on the three broad categories: intentional torts, negligence, and strict liability. Landmark cases like Donoghue v. Stevenson established the modern law of negligence, while Rylands v. Fletcher laid the groundwork for strict liability. Understanding tort law is essential for businesses to manage risk, from premises liability to product safety.

5.1 What is a Tort?

A tort is conduct that causes harm to another and gives rise to civil liability. The word comes from the Latin tortus, meaning twisted or wrong. Tort law aims to:

• Compensate victims for their losses (e.g., medical bills, lost wages, pain and suffering).
• Deter harmful behavior by imposing liability.
• Promote fairness and social order by holding wrongdoers accountable.

Tort vs. Crime vs. Contract

• Crime: A public wrong prosecuted by the government; punishment can include imprisonment. A tort is a private wrong; the remedy is damages.
• Contract: Duties are created by agreement; tort duties are imposed by law regardless of consent. The same act can be both a tort and a crime (e.g., assault).

5.2 Categories of Torts

Torts are generally divided into three categories:

• Intentional Torts: Harm caused by deliberate conduct (e.g., assault, battery, defamation, trespass).
• Negligence: Harm caused by careless conduct that falls below the standard of care (e.g., a driver running a red light).
• Strict Liability: Liability without fault for ultrahazardous activities or defective products (e.g., blasting operations, product defects).

5.3 The Birth of Modern Negligence: Donoghue v. Stevenson

Before 1932, liability for negligence was limited. The landmark case Donoghue v. Stevenson changed that. A friend bought Mrs. Donoghue a ginger beer in a cafe. The bottle contained a decomposed snail, which made her ill. She could not sue the cafe (no contract) and could not sue the manufacturer (no privity). The House of Lords held that manufacturers owe a duty of care to consumers. Lord Atkin formulated the “neighbor principle”: you must take reasonable care to avoid acts or omissions that you can reasonably foresee would likely injure your neighbor.

Impact: This case established the modern law of negligence and the duty of care owed by manufacturers to end users. It opened the door to product liability and expanded tort liability dramatically.

5.4 Strict Liability: Rylands v. Fletcher

In Rylands v. Fletcher (1868), the defendant built a reservoir on his land. Water broke through and flooded the plaintiff’s mine. The court held that a person who brings something onto their land that is likely to cause mischief if it escapes is strictly liable for the resulting damage, regardless of fault. This principle was later extended to ultrahazardous activities (e.g., blasting, storing toxic chemicals). Strict liability also applies to defective products under product liability law.

5.5 Tort Law in Business

Tort law affects virtually every business activity:

• Premises Liability: Businesses owe a duty to keep their premises safe for customers and invitees. A slip‑and‑fall case can result in substantial damages.
• Product Liability: Manufacturers, distributors, and retailers can be held strictly liable for defective products that cause injury.
• Defamation: False statements about a business or its products can lead to liability for libel or slander.
• Negligent Hiring/Retention: Employers may be liable if they hire or keep an employee they know or should know poses a risk of harm to others.

📊 Real-World Example: Negligence in Retail

Scenario: A grocery store fails to clean up spilled liquid in an aisle for over an hour. A customer slips and breaks her wrist. She sues for negligence.

Application: The store owes a duty of care to maintain safe premises. The long delay suggests constructive notice (should have known). Breach is clear, causation is direct, and damages are medical bills and pain. The store may be liable.

🧠 Summary

Tort law provides remedies for civil wrongs that cause harm. It is divided into intentional torts, negligence, and strict liability. Donoghue v. Stevenson established the modern duty of care, while Rylands v. Fletcher laid the foundation for strict liability. Businesses face tort exposure in many areas, including premises liability, product liability, defamation, and negligent hiring. Understanding tort principles helps businesses manage risk, implement safety protocols, and respond effectively when accidents occur.
