Armed Forces Act (AFSPA), 1958 is an act of the Parliament of India that grants special powers to the Indian Armed Forces to maintain public order in "disturbed areas". According to the Disturbed Areas Act, 1976 once declared 'disturbed', the area has to maintain status quo for a minimum of 3 months. One such act passed on 11 September 1958 was applicable to the Naga Hills, then part of Assam. In the following decades it spread, one by one, to the other Seven Sister States in India's northeast. Another one passed in 1983 and applicable to Punjab and Chandigarh was withdrawn in 1997, roughly 14 years after it came to force. An act passed in 1990 was applied to Jammu and Kashmir and has been in force since.
