Consumer law covers most of the products we buy today. We presume that what we buy is regulated by certain minimum standards. Furniture must meet some minimum health and safety requirements. Electrical goods must work, must not be a danger to the consumer, and must last a minimum period. Cars must meet mechanical, electrical, design and other minimum standards. Several laws and regulations govern the manufacture, transport and sale of goods. Most of the time, the goods we purchase ‘work’: the chair does not collapse, the kettle boils, and the car stays on the road. However, if faults are discovered, purchasers can, and do, return to the shop with the defective goods and so it is not unusual for kettles, shoes, and even cars to be exchanged.
