Sources in the national capital say that CBI officials are working overtime to file an appeal with the Supreme Court against the 2G verdict of a special CBI Court in Delhi.

Pronounced on 21st December last year by Justice O.P. Saini, the verdict gave a 'clean chit' to former Union Telecom Minister A. Raja of the DMK and the party's high-profile Rajya Sabha M.P. Kanimizhi. In absolving them from the multi-crore 2G scam, the Court also pulled up the CBI for failing to substantiate its allegations against the duo and 11 others with solid evidences.

The scam, reported in the media as worth Rs.1.75 lakh crores, related to allocating frequencies to telecom operators and broke out during the middle of the last decade when the Congress-led UPA, of which the DMK was a staunch ally, was in power at the Centre. Charge-sheets were filed by the CBI against Raja, Kanimozhi, former Telecom Secretary Siddharth Behera and 10 others for their involvement in the scam.

After last December's verdict, both the CBI and the Enforcement Directorate had said that they would be filing appeals with the Supreme Court challenging the verdict. Now that the Union Ministry of Law & Justice has accorded permission to these agencies to challenge the special CBI Court's verdict, both the CBI and the ED officials are working overtime to complete the preparatory work to file appeals with the apex Court.
