The Delhi Police had sought permission for conducting lie detector tests on Mr Chandra, Zee News head Chaudhary and Zee Business Editor Ahluwalia and collecting their voice samples. The court had issued the three notices to know their response.
Mr Chandra and his son Puneet Goenka, who is the managing director of Zee Group, have been questioned twice in the case.
Mr Chaudhary and Mr Ahluwalia were arrested on November 27 for allegedly trying to extort Rs 100 crore from Congress parliamentarian Naveen Jindal's company Jindal Steel Private Limited (JSPL). In return, they allegedly offered to bury news reports linking JSPL to the coal allocation scam.
Mr Chaudhary and Mr Ahluwalia are in judicial custody till December 22 and lodged at the Tihar Jail in Delhi. The charges against them include extortion, cheating and criminal conspiracy.
Mr Chandra has threatened to file a defamation case against Mr Jindal. His Zee Group says the arrests of its editors are politically motivated.
