Examine the privacy and exclusion concerns raised by linking identity documents across the electoral and welfare domains, in light of the Election Laws (Amendment) Act, 2021.

The Election Laws (Amendment) Act, 2021 allows Electoral Registration Officers to ask for Aadhaar, on a voluntary basis, to establish a voter's identity [1]. In November 2026 the Panchayati Raj Minister proposed using the voter ID plus biometrics as the basis for welfare [2]. That would reverse the link, merging the citizen-as-voter with the citizen-as-beneficiary.

Safeguards under the 2021 framework

• Voluntary linking: the ECI began collecting Aadhaar voluntarily from 1 August 2022 [3].
• "Sufficient cause" clause: no one can be refused enrolment or deleted for being unable to give Aadhaar; other documents may be accepted instead [4].
• In Parliament, members argued the Bill conflicted with Puttaswamy, which limited Aadhaar requirements to state benefits [5].

Privacy concerns

• Purpose creep: Aadhaar is sought only "for establishing identity" on the rolls [1]. No law has been cited for using the voter ID for welfare. That fails Puttaswamy's test of legality, necessity and proportionality.
• Voter profiling: joining benefit data with booth-level voting data makes it possible to map beneficiaries and target patronage.
• Weak consent: once records are linked, they are hard to separate, so consent becomes a one-time formality.

Exclusion concerns

• Narrower base: welfare is for eligible residents, but voter IDs cover only enrolled adult citizens. Children, migrants and people wrongly removed from the rolls would lose out [2].
• One error costs twice: a single deletion from the roll would cut off both the vote and the pension. The vote has a sufficient-cause protection [4]; welfare would not.
• Biometric failure: worn fingerprints shut out manual workers and the elderly.
• MGNREGA precedent: the Centre says job cards cannot be deleted for not being linked under ABPS. Yet it had to issue a January 2025 SOP requiring Gram Sabha verification and a right of appeal [6]. Linking drives clearly create pressure to delete.
• Gatekeeping: some Delhi pensions already need a voter ID and a councillor's or MLA's endorsement [2].

Way forward

• Publish the fraud data behind the claim that Aadhaar is made "at every street corner" [2].
• Pass a law with a sufficient-cause safeguard and alternative documents [4].
• Provide offline, non-biometric fallbacks and a restoration route from the start [6].
• Assess the family cards already running in 10 States before building a third system [2].

Cutting leakage is a fair goal, but identity linking must not turn welfare into something that depends on electoral status. Voluntary linking, legal backing and a safety net against wrongful exclusion would protect Article 21 privacy and the spirit of SDG 16.9 (legal identity for all).
