Agarwal opposed the agency's plea contending that he was "apprehending manipulation" by CBI to implicate him in the case.
CBI had moved the court seeking direction to five arrested accused to record their voice samples for the ongoing probe.
Advocate Vijay Aggarwal, who appeared for Ved Prakash Agarwal, argued that when the accused were in police custody, CBI had sought their consent for giving voice samples but Agarwal had refused.
Apart from Agarwal, CBI has also sought voice samples of accused Jain, Bhushan Steel Limited Vice Chairman and Managing Director Neeraj Singal, Vineet Godha and Puneet Godha.
