Besides Raja and Kanimozhi, the special court had on December 21 last year acquitted 17 others, including DMK supremo M Karunanidhi's wife Dayalu Ammal, Shahid Balwa and Vinod Goenka of STPL, Asif Balwa and Rajiv Aggarwal of Kusegaon Fruits and Vegetables Pvt Ltd, film producer Karim Morani, P Amirtham and Sharad Kumar, Director of Kalaignar TV.
ED, in its charge sheet, had alleged that Rs 200 crore was paid by Swan Telecom (P) Ltd (STPL) promoters to DMK-run Kalaignar TV.
On the same day, the trial court had acquitted Raja, Kanimozhi and 15 others, including former Telecom Secretary Siddharth Behura, Raja's erstwhile private secretary R K Chandolia, Swan Telecom promoters Shahid Usman Balwa and Vinod Goenka, Unitech Ltd MD Sanjay Chandra and three top executives of Reliance Anil Dhirubhai Ambani Group (RADAG) -- Gautam Doshi, Surendra Pipara and Hari Nair, in the CBI's 2G case.
The CBI had alleged that there was a loss of Rs 30,984 crore to the exchequer in allocation of licences for the 2G spectrum which were scrapped by the top court on February 2, 2012.
Special Judge O P Saini, however, had then held that the prosecution had "miserably failed" to prove the charges.
The special court, which was set up on March 14, 2011 for hearing 2G cases exclusively, had also acquitted Essar Group promoters Ravi Kant Ruia and Anshuman Ruia and six others in a separate case arising out of the 2G scam probe.
The first case, prosecuted by CBI, had 17 accused, while the second matter, pursued by ED, had 19 undertrials. The third one had eight accused including Essar promoters.
In the CBI case, Raja, Kanimozhi and 15 others were tried under provisions of the IPC and the Prevention of Corruption Act dealing with offences of criminal conspiracy, cheating, forgery, using as genuine fake documents, abusing official position, criminal misconduct by public servant and taking bribe.
