Insulting remarks made to a person belonging to Scheduled Castes and the Scheduled Tribes within four walls of the house with no witnesses does not amount to offence, the Supreme Court said on Thursday as it quashed the charges under the SC/ST Act against a man who had allegedly abused a woman within her building. SC said that “all insults or intimidations to a person will not be an offence under the SC/ST Act unless such insult or intimidation is on account of victim belonging to Scheduled Caste or Scheduled Tribe”
