New Delhi, May 11 (IANS) : The Supreme Court on wednesday struck down a Telecom Regulatory Authority of India (TRAI) notification obligating telecom service providers to compensate consumers for dropped calls.

An apex court bench of Justice Kurian Joseph and Justice Rohinton Fali Nariman struck down the December 16, 2015 notification as it set aside a Delhi High Court judgement upholding the TRAI notification.

Pronouncing the judgement, Justice Nariman said the TRAI notification was unreasonable, arbitrary and non-transparent.

The service providers, during the hearing, had contended that TRAI decision was a "populist" measure to accommodate consumers as call drops were happening for host of external considerations not attributable to them.

However, TRAI had defended its decision to impose the call drop penalty, describing it as a "least invasive way to deal with the issue" and told the apex court that the service providers must enhance their investment in infrastructure as they were earning huge revenues.
