I have now been able to get this information relating to the one day ban on NDTV :
A perusal of the same shows that the ban is on ' live coverage ' of anti terrorist operations of the security forces, ( vide para 6 of the Programme Code of the Cable TV Network Rules, 1994 ) and not on reporting of anti terrorist operations. There is a clear distinction between the two. NDTV did not show any live coverage of the anti terrorist operations, but only reported about them.
Thus the ban was clearly illegal
