The application to the apex court came after Reliance Natural Resources also accused the Mukesh Ambani-led company of charging an 'illegal and unauthorised' marketing margin on sale of gas from the Krishna-Godavari basin.

The company said this would lead to a loss of Rs.10,000 crore to the government.

'The so-called marketing margin is nothing but a device illegally adopted by Reliance Industries to charge a higher sale price, without even paying the lawful share of such revenues to the government.'
