The Telecom Regulatory Authority of India has approached a Delhi court against Loop Mobiles (India) Ltd for rejecting its subscribers'' requests to switch over to other service providers.

"Regulation 12 (Telecom Portability Regulations) does not provide for rejection of porting requests on ground of Act of God and rejection under the category are not in consonance with the provisions of the said regulation," TRAI said in its complaint.

Seeking Chief Metropolitan Magistrate Vinod Yadav's direction to summon and prosecute Loop Mobiles, its Managing Director Sandip Basu and Chief Regulatory Officer Harish Kapoor for rejecting subscribers' requests for number portability, Trai said Loop Mobiles rejected some requests for number portability in Mumbai circle as it was "not in consonance with the provisions of the Telecom Mobile Number Portability Regulations".

Trai had  issued a draft of regulations for introduction of mobile number portability (MNP) in the country in January  2011.  MNP allows subscribers to retain their existing telephone number when they switch from one access service provider to another access service provider irrespective of mobile technology or from one technology to another technology on the same or any other access service provider.

It said to ascertain correctness of compliance given by Loop, TRAI obtained data pertaining to rejections of porting requests by the company in Mumbai circle and observed that it had rejected a number of such requests under the category of "act of God" and certain on ground of "contractual obligations" and "outstanding payment dues".
