The Competition Act was enacted by the Indian parliament in December 2002 and received the assent of the president of India in January 2003. The Competition Act prohibits anti-competitive agreements and abuse of a dominant position, and regulates combinations. The Competition Act also promotes competition advocacy. The provisions relating to anti-competitive agreements and abuse of a dominant position and other related provisions of the Competition Act were enforced with effect from 20 May 2009 (see the notification dated 15 May 2009). The provisions relating to regulation of combinations came into force on 1 June 2011 (see the notification dated 4 March 2011).
