A Delhi special court today asked the CBI to clarify whether rule of law was followed in allocation of coal blocks to top industrialist Kumar Mangalam Birla's Hindalco.

During the hearing on the closure report filed by the CBI in its FIR lodged against Birla, former coal secretary P C Parakh and others, the court asked the agency whether there was an act of omission or commission in the allocation of blocks to Hindalco.

CBI told the court that during their probe, they have not found any criminality in allocation of coal blocks to Hindalco.

CBI said that initially the screening committee had not recommended allocation of coal blocks to Hindalco but later on it reviewed its decision at the request of Birla and said that blocks be given to Hindalco.

The CBI, on August 28, had filed a losure report in thecase in which it had earlier lodged FIR against Birla, Parakhand others in one of the coal blocks allocation scam cases.

The FIR against Birla, Parakh and others was registered in October last year by CBI which had alleged that Parakh had reversed his decision to reject coal block allocation to Hindalco within months what it called without any valid basis or change in circumstances and shown undue favours.

The FIR related to allocation of Talabira II and III coal blocks in 2005 and CBI had booked Birla, Parakh and otherofficials of Hindalco under various IPC sections, including criminal conspiracy and criminal misconduct on the part of government officials.
