The High Court had termed as "populist" the decision of the AAP government to have CAG audit of discoms -- Tata Power Delhi Distribution Ltd (TPDDL), BSES Rajdhani Power Ltd and BSES Yamuna Power Ltd, which supply power in Delhi.
There can be no other audit by CAG at the instance of the state government when regulatory body, Delhi Electric Regulatory Commission, is already there to audit the accounts of the discoms, it had said.
The court had made the observations while quashing the Delhi government's January 7, 2014 directive to carry out an audit of the three discoms by the CAG.
It had also not agreed with the government's contention that the audit was ordered in public interest for determining the tariff, saying "determination of tariff is in sole domain of DERC which is well empowered to itself conduct the same or have the same conducted and the report of CAG audit of discoms has no place in the Regulatory Regime brought about by the Electricity Act and the Reforms Act".
