President of India Pranab Mukherjee on 28 May 2015 gave his assent to the Constitution (119th Amendment) Bill, 2013 that related to the Land Boundary Agreement (LBA) between India and Bangladesh.
Earlier, the bill was unanimously passed by both the houses of the Parliament in May 2015.
It is the 100th amendment to the Indian Constitution and amends its first schedule.


The Constitution (100th Amendment ) Act, 2015, as it is called now, is intended to operationalise the May 1974 LBA that pertains to exchange of certain enclaves of land between both the countries.

Background
The exchange will see Bangladesh take over 111 enclaves (17160 acres) from India’s possession and India, in turn, receive 51 enclaves (7110 acres) from Bangladesh.
In Assam, India will get 470 acres of land from Bangladesh, while 268 acres will go to Bangladesh. Enclaves are tiny landlocked territories that each country has within the borders of the other nation. The enclaves in Assam, West Bengal, Tripura and Meghalaya come under the bill’s ambit.
