Reliance Natural Resources Ltd (RNRL), a firm of Anil Ambani group, has filed an intervention plea in the Supreme Court seeking permission to intervene in the ongoing NTPC-RIL gas dispute.

The RNRL has claimed that the issues raised by the state owned power PSU have a direct effect on its own case against the RIL.

Currently, Mukesh Anbani led RIL and Anil Ambani led RNRL, are in a gas row. The case is in the Supreme Court and RNRL is asking for gas at $2.34 per mmBtu.

RNRL, in its argument for the intervention plea, has said that the issues that have come up during NTPC-RIL case are of direct significance for its own case against Mukesh Ambani led Reliance Industries.

RNRL has said that RIL's arguments for having amendments to its written statements in NTPC suit, is an issue in the SLP (special leave petition) filed by RIL in the Supreme Court in the RIL-RNRL matter.

Earlier, on September 5, NTPC moved the Apex court challenging a verdict by Bombay High Court that had permitted RIL to have amendments in its petition on the gas dispute citing the government's pricing policy.

A Division Bench of the High Court had taken the decision when RIL had requested that the government's gas pricing policy could proof disturbing to its contract with NTPC.

NTPC had moved the Bombay High Court to obtain 12 mmscmd gas from RIL, which had won the global competitive bid by quoting a price of $2.34 per mmBtu.
