About 6th Schedule

The Constitution of India makes special provisions for the administration of the tribal dominated areas in four states namely Assam, Meghalaya, Tripura and Mizoram.

As per article 244 and 6th Schedule, these areas are called “Tribal Areas”, which are technically different from the Scheduled Areas under fifth schedule.
The Governors of these four states are empowered to declare some tribal dominated districts / areas of these states as autonomous districts and autonomous regions.
It provides for the creation of autonomous District and Regional Councils in these tribal areas and they enjoy a certain degree of administrative, legislative, judicial and financial autonomy.
