Discuss the constitutional and administrative challenges in addressing demographic change caused by illegal immigration in India. Examine the mandate of the High-Level Committee on Demographic Change in this context.

Demographic shifts along India's borders, framed by the government as a threat to sovereignty and social harmony, prompted PM Modi's "High-powered Demography Mission" (15 Aug 2025) and a High-Level Committee to study "abnormal" change from illegal infiltration [1]. Addressing it, however, tests both the Constitution and the administrative machinery.

Constitutional challenges

• Federal friction: population, migration and public order straddle the Union and State lists, so any Centre-led assessment needs State cooperation (Article 256/257) yet risks resistance in non-aligned States [2].
• Rights safeguards: profiling by religious and social community invites Article 14/15 (equality, non-discrimination) and Article 21 (life, due process) scrutiny [1].
• No statutory basis: constituted by Cabinet approval (11 Sep 2025), not an Act; its recommendations need separate legislation—amendments to the Foreigners Act, 1946 or Citizenship Act—to bind [1].

Administrative challenges

• Detection and deportation: identifying illegal immigrants demands reliable data, functioning Foreigners Tribunals and diplomatic uptake by source states [1].
• Data gaps: absence of a current Census/NPR baseline weakens credible measurement.
• Inter-ministerial coordination and State field visits via a detailed questionnaire strain capacity [2].

Mandate of the Committee (examine)

• Chaired by Justice P.P. Navlekar (Retd.), with the Census Commissioner ex-officio, it must scientifically assess change from illegal immigration, analyse community-level patterns, and recommend policy, legislative and administrative remedies, including a permanent identification-deportation mechanism [1].
• Reports within one year, extendable by six months [1].

If the Committee anchors its recommendations in due-process safeguards and cooperative federalism, it can reconcile national security with constitutional guarantees, converting a contested exercise into credible migration governance.
