"Hindalco reiterates that none of its officials, including its Chairman Kumar Mangalam Birla, have pursued any unlawful or inappropriate means for securing the allocation of the coal block," the company said in a statement.
It further said that Hindalco would study the order of the court in detail "and would defend its case through legal process."
"The company had represented its case to the concerned authorities in a transparent and lawful manner, following which it was allocated a 15 per cent share in the combined Talabira-II and III coal block in November 2005, in a JV with Mahanadi Coalfields Limited and Neyvili Lignite Corporation, both public sector undertakings with an 85 per cent stake," it said.
The coal block was deallocated in 2014.
"The plant is already operational even though Talabira-II & III coal block could not become operational for want of clearances. Consequently, Hindalco is having to suffer irrecoverable financial stress," the company said.
