The three power discoms in Delhi Wednesday filed a plea in the Delhi High Court challenging the CAG's authority to audit their finances.
On January 1, Lt. Governor Najeeb Jung directed the Comptroller and Auditor General (CAG) to undertake the audit of the discoms.
Chief Minister Arvind Kejriwal, soon after assuming office Dec 28 last year, met CAG Shashi Kant Sharma, and urged him to audit the three private firms that supply power to the city's residents. He alleged that the discoms were over-charging the consumers.
The three companies have now challenged the proposed audit, contending that the CAG's writ does not run over them.
