Which apex authority in India issued a mandatory directive in November 2016 ordering all cinema halls across the country to play the National Anthem before movie screenings?

On November 30, 2016, a bench of the Supreme Court of India passed an interim order directing that all cinema halls across the nation must play the National Anthem before the screening of a movie, and that everyone present inside the theater must stand up to show respect. (Note: This order was later modified and made optional by the apex court in January 2018).
