Indian shares slipped on Friday, weighed down by telecom and banking stocks after the Supreme Court rejected pleas from mobile operators for relief on dues owed to the government.
The Supreme Court dismissed petitions by wireless carriers, including Bharti Airtel and Vodafone Idea, seeking a review of its order late last year that they must pay the bulk of nearly $13 billion in dues to the government.
The decision has affected market sentiment, with banks likely to be impacted, said Neeraj Dewan, director at Quantum Securities, adding that weak sentiment may also have some negative impact on foreign direct investment.
The NSE Nifty 50 index was down 0.19 percent to 12,332 by 0406 GMT, while the benchmark S&P BSE Sensex slipped 0.16 percent to 41,866.16.
Vodafone Idea Ltd, whose survival could be threatened after the court's decision, fell a record 40 percent to a two-month low.
Conglomerate Grasim Industries Ltd, a shareholder of Vodafone Idea, dropped 6 percent.
Telecom tower company Bharti Infratel Ltd slumped 13.5 percent in its sharpest intraday drop in nearly three years and was the biggest loser on the Nifty.
