New Delhi: The Delhi high court today refused to grant early hearing on the CBI's appeal challenging the acquittal of former Union telecom minister A Raja and others in the 2G spectrum allocation scam case.

The court was hearing the CBI's plea seeking to advance the date of hearing from October 24 in its appeal against the acquittal of all the accused.

Justice AK Chawla said the matter would be heard on the date already fixed and added that it would be expected of all parties to join the hearing.

Additional solicitor general Sanjay Jain, representing the Central Bureau of Investigation (CBI), submitted that early hearing was needed as the country was on the verge of facing a huge amount of arbitration under bilateral investment treaties. The application was opposed by the counsel for the accused.

A special court had on December 21, 2017 acquitted A Raja, DMK lawmaker Kanimozhi and others in CBI and Enforcement Directorate (ED) cases related to the scam.

It had acquitted 17 others, including DMK chief M Karunanidhi's wife Dayalu Ammal, Vinod Goenka, Asif Balwa, film producer Karim Morani, P Amirtham and Sharad Kumar, director of Kalaignar TV in the ED case.

On the same day, the trial court had also acquitted former telecom secretary Siddharth Behura, A Raja's erstwhile private secretary R K Chandolia, Unitech Ltd MD Sanjay Chandra, three top executives of Reliance Anil Dhirubhai Ambani Group (RADAG) -- Gautam Doshi, Surendra Pipara and Hari Nair, in the CBI's 2G case.

Swan Telecom promoter Shahid Usman Balwa and Vinod Goenka and directors of Kusegaon Fruits and Vegetables Pvt Ltd Asif Balwa and Rajiv Agarwal were also acquitted in the CBI case.

 On March 19 last year, the ED had approached the high court challenging the special court's order acquitting all the accused.

A day later, CBI too had challenged in the high court the acquittal of the accused in the case.

The ED, in its charge sheet, had alleged that Rs 200 crore was paid by STPL promoters to DMK-run Kalaignar TV.

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 OP Saini, however, had 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.

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.
