RCom had to pay the amount to Ericsson by September 30 but the company approached SC seeking a 60-day extension. As Ericsson did not agree to the extension, it has now filed a contempt of court petition.
SC will hear the plea of RCom on October 4 whereas a date is not finalised for Ericsson. However, sources say Ericsson's petition can also be taken up on October 4.
Meanwhile, the National Company Law Appellate Tribunal will hear the matter on October 3. The tribunal has asked the two parties to settle the disputes.
Queries sent to the companies remained unanswered.
