Defect
Also called: Defective goods, Manufacturing defect
Under Section 2(10) of the Consumer Protection Act, 2019, any fault, imperfection or shortcoming in the quality, quantity, potency, purity or standard of goods required by law, contract or the trader's claim.
Explained
The word defect is used loosely in many statutes, such as a formal defect in a plaint under the CPC. Its defined meaning is in Section 2(10) of the Consumer Protection Act, 2019: any fault, imperfection or shortcoming in the quality, quantity, potency, purity or standard which is required to be maintained by or under any law for the time being in force, or under any contract, express or implied, or as is claimed by the trader in any manner whatsoever, in relation to any goods or product. The expression defective is construed accordingly.
The standard is measured against three benchmarks: the law, the contract, and the trader's own claim. A product may therefore be defective even if it meets legal standards, when it falls short of what the label or advertisement promised. Defect relates to goods. For services, the Act uses deficiency, defined in Section 2(11) as a fault, imperfection, shortcoming or inadequacy in the quality, nature and manner of performance. Confusing the two is a common error.
A complaint may allege that goods bought or agreed to be bought suffer from one or more defects (Section 2(6)(ii)). Where the defect cannot be determined without analysis, the District Commission sends a sample to an appropriate laboratory under Section 38(2). If satisfied, it may direct the opposite party under Section 39 to remove the defect pointed out by the laboratory, replace the goods, refund the price or pay compensation.
Defect is also the foundation of product liability, defined in Section 2(34). Under Section 84, a product manufacturer is liable if the product has a manufacturing defect, is defective in design, deviates from manufacturing specifications, does not conform to an express warranty, or lacks adequate instructions or warnings. Section 84(2) makes him liable even if he proves he was not negligent or fraudulent in making the express warranty.
