Reliance Natural Resources said the government had prior knowledge of its gas supply understanding with Reliance Industries and that it was incorrect to maintain that the same came to light only from the Bombay High Court order.

On June 15, the Bombay High Court had decided in favour of Reliance Natural Resources and issued a directive to Reliance Industries to supply 28 million units of gas per day to the Anil Ambani group company at $2.34 per unit.

But Reliance Industries challenged the verdict in the Supreme Court. The apex court fixed next date of hearing of the case for Oct 20, allowing all interested parties to file their file their replies and rejoinders by then.

The Anil Ambani group has already asked the Supreme Court to make the state-run power utility NTPC a party to its dispute with Reliance Industries, since their positions were similar for gas supplies from the Krishna-Godavari basin.
