"...Many of the leading operators, who were constantly demanding spectrum for meeting QoS (Quality of Service) parameters of TRAI, appeared to form a cartel and declined to take part in the auction in 2012/3," CAG is learned to have communicated to the Telecom Ministry seeking its comments in a draft report.
CAG had earlier calculated that the spectrum allocation to the companies without auction in 2008 caused government presumptive loss of Rs 1,76,000 crore.
The CAG added that declining to participate in auction negated their telecom operators position of seeking additional spectrum.
"If additional spectrum was vital for maintaining TRAI prescribed QoS, then reluctance of the operators to take spectrum at price in the last two auction appeared to be a significant departure from their earlier stand," CAG said.
No comments were received from the companies named in the report.
