After independence, the constitution was created to protect all the citizens. But the root of the caste system of racism has gone so deeply in India, that inhuman atrocities were not reduced with the exploited class of society. Concerned about these incidents, then Prime Minister Rajiv Gandhi stressed the need to take steps to make the necessary legislation to ban the atrocities on the SC/ST castes.
In a speech given on Independence Day on August 15, 1987, he announced that an Act would be passed if necessary to investigate atrocities. After that, the then Congress government led by Rajiv Gandhi passed the bill of Scheduled Caste and Scheduled Tribe (Prevention of Atrocities) Act, 1989 on September 11, 1989, from both the houses of the Parliament. But before the implementation of this act, the General election for Lok Sabha has started. In that election Congress did not get majority for make government.
Than the new coalition government of National Front and BJP implemented this rule from 30th January 1990. At that time VP Singh was the prime minister.
This act applies to every person who is not a member of Scheduled Castes and Scheduled Tribes and that person harasses members of this class. This Act had 5 chapters and 23 Articles.
So, the main credit of making this SC/ST Act 1989 goes to the Congress, while the credit for the implementation of this SC/ST Act 1989 goes to the “National Front and the BJP Government”.
Later, the amendment was made on 23 June 2014 in this Act. In August 2018, the BJP government of the Center made the act even more rigid. By adding several articles to this Act, this act becomes to non-anticipatory bail act.
