Advancing his arguments opposing framing of charges against him, Chandolia said he was only an official to assist Raja in day-to-day work.
"A Raja was the (telecom) minister and my master. I merely carried out his instructions," advocate Vijay Agarwal, appearing for Chandolia, told Special CBI judge O P Saini.
"I was his (Raja`s) sophisticated helper. I am only an extra assisting hand to carry out instructions of my master. Can I question my master? How can an assisting staff be roped in by the CBI?" he asked.
He submitted he is not a person associated with the DMK, Kalaignar TV or any other telecom company.
Chandolia, who began his arguments today opposing framing of charges against him, also challenged the CBI to show a single document as evidence on which he has put his signature.
Before he began his arguments, the court dismissed his plea seeking interim bail on the ground that the CBI lacks proper sanction to prosecute him in the case.
