ED, in its charge sheet, had alleged that the accused were involved in a Rs 200-crore money transaction.
Kanimozhi told Special CBI Judge O P Saini that there were no documents to substantiate the allegation against her.
The allegation on Kanimozhi is that she and ex Telecom Minsiter A Raja had arranged the illegal gratification of Rs 200 crore.
Grover also told the court that the complaint filed by ED and documents annexed along with the charge sheet prima facie show that it was not a genuine business transaction.
Special CBI Judge O P Saini, said the order was still incomplete and deferred judgment.
Kanimozhi had moved to the SC seeking quashing of the charges against her in the 2G scam.
The court has fixed the matter for Wednesday for further arguments on the bail pleas and framing of charges.
The court directed ED to supply all the documents to the accused during the day itself and asked the defence counsel to complete the scrutiny by May 30.
The accused, who appeared before the court in pursuance to the summons issued against them, moved their bail pleas.
Recording her statement, Kanimozhi told Special CBI Judge O P Saini that prosecution witnesses had deposed against her under CBI pressure.
Besides these 14 accused, three telecom firms are also facing trial in the case.
