The PMO denied any criminality in the allocation of the coal block to a joint venture, including Kumar Mangalam Birla headed Hindalco, while making it clear that Singh was the 'competent authority' who cleared the proposal for Talabira coal block allotment mooted by the Coal Ministry in 2005.
It acknowledged that the final decision of October 1,2005 "differed" from the earlier recommendation of the screening committee and released details of the sequence of events which suggested that the norms set by the Prime Minister were relaxed in view of representations made by Birla and Odisha Chief Minister Naveen Patnaik.
While defending the decision, the PMO referred to Singh's statements earlier that the government has nothing to hide and it will fully cooperate with CBI which is probing the case.
The allocation of Talabira coal block in Odisha is in the eye of a storm with CBI booking Aditya Birla Group Chairman Kumar Mangalam Birla and former Coal Secretary P C Parakh four days back.
Acknowledging that the final decision was taken on an altered recommendation, the PMO said, "This was done following a representation received in the Prime Minister's Office from one of the parties, which was referred to the Ministry of Coal," an apparent reference to Birla's two letters.
The PMO said CBI is free to investigate the case as it may have got hold of some documents post-allocation.
