The consumer protection act was enacted in 1986 to protect consumer interests in India. It established a 3-tier system for consumer dispute redressal - district forums for disputes less than 20 lakh rupees, state commissions for 20 lakh to 1 crore disputes, and the national commission above 1 crore. The act defines key terms like complaints, consumers, defects and deficiencies. It also lays out the various consumer rights and remedies available under the act such as removal of defects, replacement of goods, refunds and compensation. A case example is provided where a doctor was ordered to pay 2 lakh rupees in damages for providing wrong treatment to a patient suffering from meningitis.
