Terrorist and Disruptive Activities (Prevention) Act, commonly known as TADA, was an anti-terrorism law which was in force between 1985 and 1995 (modified in 1987) under the background of Punjab insurgency and was applied to whole of India. It came into effect on 23 May 1985. It was renewed in 1989, 1991 and 1993 before being allowed to lapse in 1995 due to increasing unpopularity due to widespread allegations of abuse. It was the first anti-terrorism law legislated by the government to define and counter terrorist activities.The Act's third paragraph gives a very thorough definition of "terrorism":"Whoever with intent to overawe the Government as by law established or to strike terror in the people or any section of the people or to alienate any section of the people or to adversely affect the harmony amongst different sections of the people does any act or thing by using bombs, dynamite or other explosive substances or inflammable substances or lethal weapons or poisons or noxious gases or other chemicals or by any other substances (whether biological or otherwise) of a hazardous nature in such a manner as to cause, or as is likely to cause, death of, or injuries to, any person or persons or loss of, or damage to, or destruction of, property or disruption of any supplies or services essential to the life of the community, or detains any person and threatens to kill or injure such person in order to compel the Government or any other person to do or abstain from doing any act, commits a terrorist act."
