Manipur
The ‘Inner Line Permit’ (ILP) is currently in force only in Arunachal Pradesh, Nagaland and Mizoram. This is a British era regulation which was designed to segregate the ‘Hill People’ of the northeast from British economic interests in tea, oil and gaming in the Brahmaputra Valley. It came into existence from Bengal Eastern Frontier Regulations of 1873, and after independence, has been kept in force by Indian governments to protect tribal society and culture from getting swamped by the mainland.
