The Mizoram government has sought the revision of the boundary with Assam, based on the Bengal Eastern Frontier Regulation (BEFR) of 1873 and the Inner Line of the Lushai Hills Notification of 1993.
The BEFR allows Arunachal Pradesh, Manipur, Mizoram and Nagaland not to let non-resident Indians in without an inner-line permit for a temporary stay.
