The SC/ST (Prevention of Atrocities) Act, 1989, criminalises a range of caste-based atrocities and provides special procedures and protections.
Section 18A, introduced through the 2018 amendment, provides that a preliminary inquiry is not required before registering an FIR.
In the IIT Bombay case, the Act has been invoked alongside an abetment-to-suicide allegation.
