"I urge the telecom minister to investigate whether the officials in DoT were colluding with the operators during 2006-10, why there is lack of oversight on the CsCA by DoT and recommend steps that can be taken to address this lack of oversight," Chandrasekhar said in a letter written to Telecom Minister Manoj Sinha dated August 24, 2016.
The Comptroller and Auditor General of India (CAG) report tabled in Parliament in March said the government has suffered a loss Rs 12,488.93 crore as six private telecom operators, including RCom, Bharti Airtel, Vodafone and Idea Cellular, understated gross revenue by Rs 46,045.75 crore from 2006-07 to 2009-10.
"During the course of audit of records maintained by CsCA for verification of deduction claims, discrepancies on various issues were noticed among different CsCAs. Also, within the same CsCA, different yardsticks were adopted for different operators due to lack of co-ordination within the CsCA," the CAG said.
The MP said the observations made by the CAG raise some serious questions on the functioning of the DoT and point to the possibility that the CsCA is "either inept to carry out its duty or some officials within the CsCA were colluding with the telecom companies".
"This means there is a difference of Rs 373.29 in the calculations of shortfall as pointed out by the DoT and the CAG reports. This difference has not been explained," he said.
The financial impact due to understatement of gross revenue stood at Rs 1,507.25 crore for RCom, Rs 1,357.68 crore (Tata Teleservices), Rs 1,066.95 crore (Airtel), Rs 749.85 crore (Vodafone), Rs 423.26 crore (Idea) and Rs 107.61 crore (Aircel), the CAG had said.
