The Competition Act, 2002 aims to promote fair competition and curb anti-competitive practices in India, replacing the Monopolies and Restrictive Trade Practices Act of 1969. It establishes the Competition Commission of India to oversee and regulate competition, with a focus on consumer welfare and market structure, including provisions against anti-competitive agreements and abuse of dominant positions. The Act outlines penalties for violations and emphasizes the need for a competitive culture among stakeholders and policymakers.
