Section 2 defines core terms that determine the Act's scope: consumer (purchasers, hirers, users and heirs, excluding resale/commercial use except livelihood by self employment); complaint (written allegation by a consumer, association, or government alleging defective goods, deficient services, unfair or restrictive trade practices or over charging); defect (fault in quality, quantity, potency, purity or standard) and deficiency (shortcomings in service performance), and detailed definitions of unfair and restrictive trade practices, trader, manufacturer, service, and adjudicatory bodies.
