NTT DoCoMo holds 26 percent stake in Tata Teleservices and rest of the stake is with Tata Group.
The Supreme Court has cancelled three CDMA licences of Tata Teleservices in its order of February 2, 2012 which quashed 122 2G permits. Later, a section of industry raised question on 19 GSM licences of Tata Teleservices and called for their cancellation.
According to sources, Department of Telecom recently received legal opinion on the matter which said that GSM permits of Tata Teleservices were not included in the licences that Supreme Court found faulty and cancelled.
Kato also denied to be in talks with Russian conglomerate Sistema, which holds majority stake in Indian telecom firm Sistema Shyam Teleservices.
