The legal provisions against violence and humiliation to Dalits and Adivasis strengthened by:

Scheduled Castes and Tribes Act, 1989

In addition to reservations, there have been a number of laws passed to end, prohibit and punish caste discrimination, specially untouchability. One of the earliest such laws was the Caste Disabilities Removal Act of 1850, which disallowed the curtailment of rights of citizens due solely to change of religion or caste. The most recent such law was the Constitution Amendment (Ninety Third Amendment) Act of 2005, which became law on 23rd January 2006. Coincidentally, both the 1850 law and the 2006 amendment related to education. The 93rd Amendment is for introducing reservation for the Other Backward Classes in institutions of higher education, while the 1850 Act was used to allow entry of Dalits to government schools. In between, there have been numerous laws, of which the important ones are, of course, the Constitution of India itself, passed in 1950; and the Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act of 1989. The Constitution abolished untouchability (Article 17) and introduced the reservation provisions mentioned above. The 1989 Prevention of Atrocities Act revised and strenthened the legal provisions punishing acts of violence or humiliation against Dalits and adivasis.
