CBI drops coal scam case against Kumar Mangalam Birla

The Central Bureau of Investigation (CBI) has closed a coal scam case against billionaire Kumar Mangalam Birla and a former top bureaucrat that emerged in 2012 after an auditor's report on revenue loss to the exchequer from allocations of coal blocks .

The CBI filed the case against Mr Birla and former Coal Secretary P.C. Parakh last year in relation to a block allocated in 2005 to Hindalco Industries, part of the $40 billion Aditya Birla Group led by Kumar Mangalam Birla.

"The evidence collected during investigation did not substantiate the allegations levelled against the persons named in the FIR (first information report filed in the case)," the CBI said in a statement late on Friday.

The CAG had alleged that the government's allocation of coal blocks may have cost the exchequer revenues of about $33 billion, although industry watchers and the previous government have cast doubts on the figure.

Though the CBI has dropped the name of Mr Birla, the Supreme Court this week ruled that allocations of coal blocks since 1993 were illegal. That would include blocks awarded to firms including Hindalco and Jindal Steel and Power Ltd.

The court will hold a further hearing on Monday, after which it will decide whether to cancel the allocations or impose some sort of penalty.
