In a big setback for telecom companies, the Supreme Court has dismissed their plea seeking correction of alleged errors in Adjusted Gross Revenue (AGR) calculation.

A bench headed by Justice L Nageswara Rao said all applications were dismissed. On July 19, the apex court already said it would pass its order on applications filed by -- Vodafone Idea, Bharti Airtel and Tata Tele Services Ltd -- alleging arithmetical errors in the calculation of AGR dues payable by them. The top court, citing an earlier order in the matter, had noted the order clearly point out that no re-assessment of AGR related dues can be done. The telcos submitted that arithmetical errors can be rectified and there are cases of duplication of entries.
