The study on “The Teeter-Totter of Regulation and Competition: Why Indian Competition Authority Must Trump Sectoral Regulators” was commissioned to National Law School of India University (NLSIU), Bangalore. The overall objective of the study was to analyze the relationship between sector specific regulators and competition authority in India. The study suggests that as per the present legislative framework, sectoral regulators and competition authority may co-exist, competition authority ought to trump sector specific regulators since, unlike Competition Authority, sectoral regulators lack any mechanism (e.g. private enforcement and damages) to ensure consumer welfare.
