Denotified Tribes are the tribes in India that were listed originally under the Criminal Tribes Act of 1871, as Criminal Tribes and "addicted to the systematic commission of non-bailable offences." Once a tribe became "notified" as criminal, all its members were required to register with the local magistrate, failing which they would be charged with a crime under the Indian Penal Code.
The Criminal Tribes Act was repealed in 1949 and thus 'de-notified' the tribal communities. This Act, however, was replaced by a series of Habitual Offenders Acts, that asked police to investigate a suspect's "criminal tendencies" and whether their occupation is "conducive to settled way of life." The denotified tribes were reclassified as "habitual offenders" in 1959.
