- Discuss the main features of the land-boundary agreement between India and Bangladesh. (Answer in 150 words)
Introduction
The land boundary settlement with Bangladesh began as the Indira-Mujib agreement of 16 May 1974, was completed by the 2011 Protocol and took effect on 31 July 2015 under the Constitution (100th Amendment) Act.

Body
1. Constitutional route: because Berubari Union (1960) held that transferring territory needs an amendment, ratification waited four decades until Parliament unanimously amended the First Schedule.
2. Exchange of enclaves: 111 Indian enclaves of 17,160 acres went to Bangladesh and 51 Bangladeshi enclaves of 7,110 acres to India, ending the statelessness of 51,000 chhitmahal residents.
3. Adverse possessions regularised: about 2,777 acres to India and 2,267 acres to Bangladesh, settled by who actually lived there.
4. Stretches demarcated: 6.1 kilometres in three sectors — Daikhata in West Bengal, the Muhuri river in Tripura and Lathitila-Dumabari in Assam.
5. Choice of citizenship: residents elected nationality without displacement, 921 moving to India, with permanent access to Dahagram-Angarpota through the Tin Bigha corridor.

Conclusion
It gave India its only fully demarcated land border, and a template of negotiated settlement. Turbulence in Dhaka since 2024 has not reopened it.
