Examine the tension between the right to privacy under Section 29 of the Aadhaar Act, 2016 and the imperatives of national security and law enforcement.

Section 29 of the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016 restricts disclosure of core biometric and identity information [1], operationalising the privacy guarantee affirmed in K.S. Puttaswamy v. Union of India (2017) [2]. The Bombay High Court's July 2026 order on fraudulently obtained Aadhaar cards shows how this safeguard now collides with investigative needs.

The privacy rationale of Section 29

• Aadhaar's constitutionality was upheld only because of strict confidentiality and purpose limitation; unrestricted disclosure would enable profiling and surveillance of a billion residents [2].
• The bar is on disclosure, not collection — a deliberate design choice reinforced by the Digital Personal Data Protection Act, 2023, which requires lawful purpose and data minimisation [3].

The security and enforcement counter-claim

• In the Bombay HC matter, an alleged Afghan national who overstayed a visa valid till 2018 obtained Aadhaar fraudulently; UIDAI invoked Section 29 to withhold enrolment documents from Mumbai Police [4].
• The Court noted agency reports linking fraudulent identity documents to anti-national activities, and directed UIDAI to share enrolment records and deportation proceedings to begin [4].
• Detection and removal of foreigners is a statutory duty under the Immigration and Foreigners Act, 2025, which penalises forged travel documents and gives the Bureau of Immigration statutory verification powers [5] — a duty frustrated if the identity trail is sealed.

The structural gap

• Aadhaar is not proof of citizenship, yet functions as de facto identity, so enrolment fraud converts a welfare tool into a shield [1].
• Coordination between State police, UIDAI and immigration authorities remains weak, forcing case-by-case judicial intervention rather than a standing legal channel.

The conflict is not privacy versus security but the absence of a calibrated exception. A narrowly drafted amendment permitting disclosure to designated agencies, on judicial or senior-officer authorisation, with audit trails and time limits, would satisfy the Puttaswamy tests of legality, necessity and proportionality [2]. Strengthening enrolment-document verification addresses the problem upstream, securing both the citizen's privacy and the nation's borders.
