How can a tribe or tribal community be included in or excluded from the list of Scheduled Tribes?
A tribe or tribal community can be included in or excluded from the list of Scheduled Tribes by an act of Parliament. The President may issue a public notification specifying the tribes or tribal communities that shall be deemed as Scheduled Tribes for a particular State or Union territory, after consulting with the Governor if it is a State. However, this notification can only be varied by subsequent legislation passed by Parliament.
