The Bangladesh Border Crisis

The Supreme Court has repeatedly recognised large-scale illegal immigration from Bangladesh as a matter akin to 'external aggression' under Article 355, which enjoins the Union to protect states against such threats.

The argument isn't about compassion; it's about control. India is a rules-based democracy with a finite capacity for jobs, housing, and welfare. When cross-border movement takes place outside the law and at scale, it erodes security, distorts local labour markets, and diverts benefits meant for Indian citizens. Nowhere is this more evident than on the India-Bangladesh frontier.

Start with the basics. India shares a 4,096.7-km land border with Bangladesh, the longest of any neighbour. As of early February 2025, the government told Parliament that roughly 3,232 km had been fenced and about 864 km remained (including ~175 km of "non-feasible" riverine or difficult terrain). The unfenced gaps are precisely where infiltration, smuggling, and human trafficking concentrate.

The affected states, West Bengal (2,216.7 km), Assam (263 km), Meghalaya (443 km), Tripura (856 km) and Mizoram (318 km) carry the brunt of these pressures. Apprehensions data underscores the persistence of illegal crossings. In a written reply to the Rajya Sabha on March 12, 2025, the government reported 2,601 Bangladeshi nationals apprehended along the border between January 1, 2024 and January 31, 2025, a month-by-month ledger that shows steady attempts through the year. In West Bengal, which hosts more than half of the land boundary, fencing still lags; as late as August 20, 2025, the Centre detailed that only 1,647.7 km of the state's 2,216.7-km stretch was fenced, with land acquisition delays holding up much of the rest. Those delays are not a technicality; they translate directly into law-and-order stress in border districts.
