Illegal immigration poses both demographic and security challenges in India's border regions. Critically examine the need for a permanent institutional mechanism for identification and deportation of illegal immigrants, keeping in view constitutional safeguards.

In his 79th Independence Day address, the Prime Minister called demographic imbalance from infiltration in border areas a national security challenge [2]. In May 2026, the MHA set up a High-Level Committee on Demographic Changes (HLCDC). Its brief is to recommend a permanent, "legal, fair and time-bound" system to identify, detain and deport illegal immigrants [1][4]. Such a mechanism is needed, but it is only legitimate if it is built on constitutional safeguards.

Why a permanent mechanism is needed

• Security: Porous borders in Assam and West Bengal enable infiltration. In Sarbananda Sonowal (2005), the Supreme Court treated large-scale influx as "external aggression" under Article 355.
• Demographic monitoring: The terms of reference cover fertility, economic migration and cross-border movement [1]. The Census Commissioner is a member, so the work can rest on official data [4].
• Rule-based process: A standing body with written procedures replaces ad hoc drives. That makes its actions easier for courts to review.
• Federal coordination: "Aliens" is a Union List subject, but police is a State subject. The HLCDC has prepared a questionnaire for States and plans State/UT visits [3]. Its brief also asks for a Centre–State framework [1].
• Legal base: The Immigration and Foreigners Act, 2025 merged four older laws into one [5].

Constitutional concerns

• Article 21 covers all persons, not only citizens (NHRC v. State of Arunachal Pradesh, 1996). Yet the 2025 Act lowers warrantless arrest power from Sub-Inspector to Head Constable rank [5].
• "Time-bound" vs "fair": Quick proceedings can wrongly catch the poor, landless and migrant workers, who often lack old documents. The Assam NRC exclusions showed this risk.
• Deportation bottleneck: The receiving country must accept the person as its citizen. Without that, a "time-bound" process can end in indefinite detention.
• Profiling risk: The terms of reference ask for analysis by religious or social community and use undefined terms like "abnormal settlement" [1]. This raises concerns under Articles 14, 15 and 19(1)(e).
• Accountability gap: It is an executive committee, and no duty to publish its report has been stated [4]. Public submissions to its portal raise privacy issues under the DPDP Act, 2023 [1].

A permanent mechanism would meet a real security and demographic need, but its legitimacy depends on due process. The way forward:

• define the key terms in law;
• base community-level analysis on Census data;
• require tribunal review before anyone is detained;
• sign readmission agreements with neighbouring countries;
• table the committee's report in Parliament.

Together these steps would balance border security with the Constitution's promise of liberty and equality for every person.
