Genesis: UIDAI 2009 → Act 2016

The Unique Identification Authority of India (UIDAI) was set up by an executive notification on 28 January 2009 under the UPA-2 (Nilekani as first Chair). The first Aadhaar number was issued on 29 Sept 2010 (to Ranjana Sonawane, Tembhli village, Nandurbar, Maharashtra). UPA tried to pass the National Identification Authority of India Bill 2010 but a Parliamentary Standing Committee rejected it in Dec 2011. NDA passed the Aadhaar Act 2016 as a Money Bill on 16 March 2016 (controversial — Speaker’s certification challenged).

The two Puttaswamy judgments

Justice K.S. Puttaswamy v. Union of India (24 Aug 2017) — 9-judge Constitution Bench unanimously held that Right to Privacy is a Fundamental Right under Article 21, overruling Kharak Singh and M.P. Sharma. Tests for privacy infringement set out: (a) law must exist; (b) legitimate State aim; (c) proportionality.

Puttaswamy II (26 Sept 2018, 5-judge bench) — reviewed Aadhaar Act under privacy test. 4:1 majority (Justice Sikri authoring, with CJI Misra, Khanwilkar & Bhushan; Justice Chandrachud dissenting) upheld the Act with these restrictions:

  • UPHELD: Section 7 mandatory linking for subsidies. PAN-Aadhaar linking (Sec 139AA Income Tax).
  • STRUCK DOWN: Section 57 (private entity use); Section 47 (only UIDAI complaint); banks and telcos cannot mandate Aadhaar; CBSE/UGC/NEET cannot mandate Aadhaar for exams; minors cannot be denied benefits for lack of Aadhaar.
  • UPHELD AS MONEY BILL: Aadhaar was correctly passed as Money Bill (the Court declined to review the Speaker’s certification — Justice Chandrachud dissented strongly).

Aadhaar Amendment 2019

Post-Puttaswamy II, the Aadhaar and Other Laws (Amendment) Act 2019 reintroduced VOLUNTARY use of Aadhaar by banks and telcos (the offline verification model). Private entities can use Aadhaar with the resident’s consent under specified circumstances. Penalties for breach were strengthened.
