BharatNotes What is VVPAT?
VVPAT (Voter Verifiable Paper Audit Trail) is an independent printer-based unit attached to the ballot unit of an Electronic Voting Machine (EVM). When a voter presses a button, the VVPAT prints a paper slip displaying the serial number, name and symbol of the chosen candidate. The slip stays visible through a transparent window for 7 seconds, after which it is automatically cut and drops into a sealed box — the voter never handles it. This gives the elector visual proof that the vote was cast as intended, while preserving secrecy.
Origin and Legal Basis
The legal framework was created by amending the Conduct of Elections Rules, 1961 through Ministry of Law and Justice notification S.O. 2470(E) dated 14 August 2013 (which added provisos to Rules 49A and 49M and new Rules 49MA and 56D). VVPAT was first deployed at the Noksen Assembly seat in Nagaland in September 2013. In Subramanian Swamy v. ECI (8 October 2013), the Supreme Court declared VVPAT "indispensable for free and fair elections" and directed phased introduction. The Union Cabinet later approved procurement of additional VVPAT units for the 2019 General Election, when they were used universally at all polling stations.

Significance and Recent Jurisprudence
VVPAT addresses the central criticism that EVMs are "black boxes" by adding a verifiable paper trail, strengthening voter confidence and providing an audit mechanism. On 8 April 2019 the Supreme Court increased mandatory physical verification from one to five polling stations per Assembly constituency/segment.
The most significant recent development is the Supreme Court verdict of 26 April 2024 in Association for Democratic Reforms (ADR) v. ECI. The Bench (Justice Sanjiv Khanna, with Justice Dipankar Datta concurring) rejected pleas for a return to ballot papers, voter self-verification of slips, and 100% counting of VVPAT slips. It noted no proven EVM-VVPAT mismatch except one 2019 instance traced to undeleted mock-poll data. The Court directed that Symbol Loading Units (SLUs) be sealed and stored for 45 days post-result, and allowed defeated candidates ranked second or third to seek an engineer-led verification of the EVM microcontroller (on payment).
UPSC Angle
For Prelims, focus on the year, manufacturers, the 2013 rules amendment, and the 7-second display. For Mains GS2, link VVPAT to electoral reforms, the ECI's role under Article 324, judicial oversight of elections, and the balance between transparency and administrative feasibility — using the 2024 ADR judgment as a contemporary illustration.
