Beginning Monday, the nearly-canned Tehelka tapes will play again as the CBI initiates a series of steps against those featured in it. The CBI will file either five or six criminal cases in court. For this, different FIRs will be lodged, each dealing with separate segments of the tapes that showed acts of alleged corruption. The FIRs may be lodged as early as Monday.As reported last month, former BJP President Bangaru Laxman will be booked, but the CBI has decided that for now, no FIRs will be filed against senior Army officers currently facing court martial proceedings. Five or six Defence Ministry officials could, however, find themselves named in a separate FIR, with transcripts from the tapes being cited as evidence against them.Despite a meeting that included CBI chief U.S. Mishra, no decision has yet been taken on whether to prosecute Jaya Jaitly. As Samata Party chief, Jaitly featured in a segment of the tapes where Rs 2 lakh exchanged hands at the residence of former Defence minister George Fernandes.CBI has moved into overdrive ever since the Government announced the winding up of the S.N. Phukan Commission in October. The agency took a tactical decision to register regular cases instead of a preliminary inquiry. But FIRs require a formal complaint, so CBI asked the Department of Personnel and Training (DoPT) to file one. The complaint came in last week from S.K. Dasgupta, a DoPT official.
