The Competition Commission of India (CCI) is issuing a notice to three state-owned oil marketing companies (OMCs) on a probe on whether they form a cartel to fix petrol prices.

The commission is also looking at the coal and fertiliser sectors, where government-owned companies dominate the market. “Law does not distinguish between government and private companies,” said Ashok Chawla, chairman of CCI, addressing the annual global investor conference here of Kotak Institutional Equities. “After the government clarified that it does not have a role to play in petrol pricing after deregulation, we have taken up the issue.”
