Section 3(3)(b) of the Competition Act, 2002, inter-alia, creates a presumption that an agreement, or practice carried on, or decision taken ,which limits or controls production, supply, markets, technical development, investments or provision of services has an appreciable adverse effect on competition and is to be treated as a prohibited agreement in terms of Section 3(1) of the Act. The Supreme Court in the case of Competition Commission of India vs. Co-ordination Committee of Artists and Technicians of W.B. Film and Television and others, had already affirmed that once an agreement falls under Section 3(3)(b) of the Act, appreciable adverse effect on competition is presumed. Therefore, if a particular agreement comes in any of the said categories, it is per se treated as adversely effecting the competition to an appreciable extent and comes within the mischief of sub-section (1).
