In a statement, that almost coincided with RCOM's charge that RIL issued a fourth letter threatening legal action on MTN discussions, the Mukesh group's flagship company said, "RCOM has refused to participate in the conciliation meetings under the alternate dispute resolutions provisions contained in the Non-Competition Agreement. RIL has commenced arbitration proceedings by nominating Justice B P Jeevan Reddy, a former judge of the Supreme Court of India as an arbitrator for the resolution of the disputes."

RCOM spokesperson, on the other hand, said that "RIL's notice for arbitration proceedings is legally and factually unwarranted".

The RCOM spokesperson accused the elder Ambani's group of ‘successfully destroying’ India's image in foreign eyes and said RIL's malafide design to derail discussions with MTN has been clearly exposed.

In the middle of the discussions between RCOM and MTN for a possible deal that could create a USD 70-billion entity, RIL had written to the two companies that it had the right of first refusal for a majority holding in the ADA group company and threatened legal action in case its rights were violated.

The letter, written in June, had led to eruption of the bitter battle between the two Ambani brothers once again, nearly three years after the two had reached a family settlement for division of the Reliance Empire.

The two sides continued to clash after the June 18, 2005 settlement every once in a while both inside and outside the courts on various issues relating to the family pact.

RCOM officials had not reached for conciliation talks on July 7, proposed by RIL.
