As per the Sixth Schedule, the four states viz. Assam, Meghalaya, Tripura and Mizoram contain the Tribal Areas which are technically different from the Scheduled Areas.
Provision has been made for the creation of the District Councils and regional councils for the exercise of the certain legislative and judicial powers.
Each district is an autonomous district and Governor can modify / divide the boundaries of the said Tribal areas by notification.
