In exercise of powers under section 11(2) of the TRAI Act, TRAI notified the Telecommunication Tariff (11th Amendments) Order, 2001, This order provided that the revised pulse rates shall be applicable to inter network calls. No hearing was given to BSNL before passing these orders by the Telecom Regulatory Authority of India Act, 1997 (as amended).

There is no dispute that BSNL was not given any hearing before a decision was arrived at by TRAI and the direction and or orders on 25th January and 7th February, 2001 were passed by TRAI.

The principles of natural justice have been grossly violated in this case. Even the post decisional
