UAPA (unlawful activities prevention act,1967)
Context:

The Tripura police have filed criminal cases against more than 70 persons, including Supreme Court lawyers, activists, journalists and religious leaders. under UAPA act,1967.

Key information about the act:

Originally enacted in 1967, the UAPA was amended to be modelled as an anti-terror law in 2004 and 2008.
In August 2019, Parliament cleared the Unlawful Activities (Prevention) Amendment Bill, 2019 to designate individuals as terrorists on certain grounds provided in the Act.
In order to deal with the terrorism related crimes, it deviates from ordinary legal procedures and creates an exceptional regime where constitutional safeguards of the accused are curtailed.
Between 2016 and 2019, the period for which UAPA figures have been published by the National Crime Records Bureau (NCRB), a total of 4,231 FIRs were filed under various sections of the UAPA, of which 112 cases have resulted in convictions.
This frequent application of UAPA indicates that it is often misused and abused like other anti-terror laws in the past in India such as POTA (Prevention of Terrorism Act) and TADA (Terrorist and Disruptive Activities (Prevention) Act).
