"CAG report is meant for Parliament. For the first time in Indian judiciary, the CAG report is being treated as the basis for a criminal investigation by the Supreme Court," said Raja, out on bail after being in jail for 15 months.
"I will seek permission in court to question the CAG myself and I hope the court will permit", he said in an interview to a Tamil TV channel Puthiya Thalaimurai.
Raja, who had to quit in the wake of the scam, said the telecom scam was a 'sham', the channel said in a release.
Raja alleged the case was fabricated against him because he stood in the way of cartels in the telecom industry.
Calling himself a victim, Raja said "I had stood in the way of this cartel and that is probably why I am in trouble now. I brought in new players to create a competitive atmosphere which resulted in increasing tele-density and bringing down call charges from Rupee one per minute to 30 paise per minute."
