Creditors of Indian wireless provider Aircel, which filed for bankruptcy earlier this month after accruing a debt mounting of roughly INR500 billion (USD7.7 billion), are continuing to mount legal challenges to recover dues, the Economic Times reports. Swedish vendor Ericsson has entered the fray, joining tower firms GTL and American Tower Corp (ATC) in filing a case with the Delhi High Court seeking arrears worth INR2.5 billion from the company. For their part, GTL and ATC have submitted requests for INR9.1 billion and INR2.2 billion, respectively. The Department of Telecommunications (DoT), meanwhile, is attempting to encash bank guarantees totalling around INR12 billion on the grounds that Aircel filed for insolvency without giving advance notice to the DoT and had not provided spectrum usage charge or licence fees for the last quarter. A representative of the DoT claimed that Aircel owed the government at least INR65 billion. The DoT’s move had been stayed by the Telecom Disputes Settlement and Appellate Tribunal (TDSAT), however, until the Supreme Court hears a separate case between Aircel and the DoT.
