The government is silent on the action taken against TV channels in a case linked to media reporting on the Tablighi Jamaat gathering at a Delhi mosque in violation of virus restrictions, the Supreme Court said today, stressing on the need of a "regulatory mechanism". "The government is silent on the action that has been taken and the power it has to regulate the TV channels. If there is no regulatory mechanism, create one or else we will hand it over to outside agency. Regulation cannot be left to the NBA (News Broadcasters Association)," Chief Justice SA Bobde said today, adding that the top court is not satisfied with the centre's affidavit which was shared in the top court, the second in the last few weeks.
