The petroleum ministry has filed a special leave petition in the Supreme Court with the plea that Krishna-Godavari gas was national property.

The Bombay High Court had decided June 15 in favour of the Anil Ambani-led Reliance Natural Resources Ltd (RNRL), with a directive to Reliance Industries to supply 28 million units of gas per day to the Anil Ambani group at $2.34 per unit.

But Reliance Industries has challenged the verdict in the Supreme Court, which has fixed the hearing of the case Sep 1 and asked all parties to the dispute to file their replies by then.
