In a surprising judgment, a special CBI court had last year acquitted all key accused, including A Raja, in the Rs 30,000 crore 2G spectrum allocation case.
Special CBI judge O.P. Saini had cleared the 19 accused of all charges, rejecting the case presented by the agency, citing lack of "prosecutable evidence".
The ED had after the CBI court's decision made clear its intention of challenging the verdict. (ANI)
