Tells Supreme Court system was not transparent

The Central Bureau of Investigation (CBI) has widened its probe in the coal block allocation scam to cover the delay in introduction of bidding. The United Progressive Alliance (UPA) government had continued with allocation of blocks through the screening committee route, as the proposal for bidding had been moving back and forth between government departments. CBI had last year limited itself to probing irregularities in the allocation of blocks, without going into the policy issue of bidding.
