Antitrust laws foster business competition by guaranteeing that economic power distribution stays stable and economies continue to grow. Antitrust laws significantly influence practically every industry and sector of business, most notably in manufacturing, transportation, distribution, and marketing. There are certain business behaviours that organisations must avoid if they want to flourish. Antitrust laws, for example, prohibit price-fixing schemes, mergers that limit competition, and predatory behaviour aimed at acquiring or retaining a monopoly. When firms like Reliance Industries, the Vedanta Group, and Bajaj Auto, Google were at the top of their market dominance, these operational flaws were abundantly visible. Antitrust laws become useless as a result of this overwhelming domination. The Competition Commission of India (CCI) adopted this rule in 2002 to counteract anti-competitive corporate practices, promote competition, and protect the interests of consumers. In India, competition policy is governed by the 2002 Competition Act. This article aims to analyse the concept, evolution, and anti-competitive practices under antitrust laws, recent case laws and do a comparative study of the legislation of the USA.
