Special public prosecutor Anand Grover wrapped up his final arguments contending that the Rs 200 crore transaction between DMK-run Kalaignar TV (KTV) and the DB Group firms was "proceeds of crime" and not genuine.
Special CBI Judge O P Saini has now fixed the case for final arguments by the defence on March 1.
The ED had earlier alleged that Rs 200 crore was paid to Kalaignar TV in lieu of grant of 2G spectrum licences to Swan Telecom Pvt Ltd (STPL) by Raja.
Grover had earlier told the court that there was "inconsistency" in the transaction which reflected that it was not genuine.
