“3. Section 2(f) of the Right to Information Act defines ‘Information’ to mean, inter alia, any information relating to any private body which can be accessed by Public Authority under any law for the time being in force. Section 12(1) of the TRAI Act, 1997 empowers the said Authority, if considered expedient by it to do so, inter alia, to call upon any Service Provider to furnish in writing such information or explanation relating to its affairs as the Authority may require. The functions of the Authority are prescribed in Section 11 of the aforesaid Act. I find merit in the contention of the learned counsel for the petitioner that the power to call for information or explanation from the Service Provider can be exercised by the Authority only if such information or explanation is required for discharge of the functions assigned to it. The aforesaid power, in my view, cannot be exercised for the purposes which are alien to the functions of the Authority specified in Section 11 of the Act. Taking a contrary view will lead to the Authority assuming unbridled power to call for information from a Service Provider irrespective of whether such information is necessary for an efficient discharge of the functions assigned to the Authority or not .”
