Supreme Court Judgment on EVM & VVPAT: Overview
India's transition from paper ballots to Electronic Voting Machines has been accompanied by periodic legal and political challenges questioning the system's transparency and tamper-resistance. These concerns intensified around the addition of VVPAT slips, which let voters visually confirm their vote before it is recorded, and led to sustained litigation over exactly how much of the paper trail should be manually counted and cross-checked against the electronic tally.
That question reached its most significant resolution in Association for Democratic Reforms & Ors. v. Election Commission of India, decided by the Supreme Court on 26 April 2024, amid the 2024 Lok Sabha election cycle. The Court declined to mandate 100% VVPAT-EVM cross-verification or a return to paper ballots, but strengthened the existing framework in specific, practical ways. This page explains the judgment, the legal and technical framework behind it, and the compliance litigation that has continued in 2025-26.
What Was the Case About?
The Association for Democratic Reforms (ADR) and other petitioners approached the Supreme Court seeking two principal reliefs: first, that all VVPAT paper slips generated during an election be manually counted and cross-verified against the electronic EVM count, rather than only a limited sample; and second, that voters be permitted to directly verify and physically deposit their VVPAT slip into a ballot box, or alternatively that India revert entirely to the traditional paper ballot system. The petitioners argued that the existing practice — counting VVPAT slips from only five randomly selected polling stations per Assembly constituency — was an inadequate sample size incapable of genuinely assuring the accuracy of results.
The Main Legal Questions
The Court had to assess, based on detailed technical submissions from the Election Commission about how EVMs and VVPATs are manufactured, sealed, and secured, whether the existing verification framework provided adequate assurance of electoral integrity, or whether the Constitution's guarantee of free and fair elections required either full VVPAT counting or direct voter verification of paper slips. The Court also had to weigh the practical feasibility — time, cost and logistics — of 100% manual counting against the stated benefits of the current EVM-based system.
Key Directions (26 April 2024 Judgment)
The following is a structured, plain-English summary of what the Court actually decided.
100% VVPAT-EVM Cross-Verification Rejected
The Court declined to direct that all VVPAT slips be manually counted and cross-verified against the EVM tally, holding that the existing sample-based verification — counting VVPAT slips from five randomly selected polling stations per Assembly constituency — provides adequate assurance, given the technical safeguards already built into the EVM-VVPAT system.
Return to Paper Ballots and Direct Voter Verification Also Rejected
The Court declined to direct reversion to the paper ballot system, observing that EVMs have curtailed booth capturing, eliminated invalid votes, and improved administrative efficiency. It similarly rejected the demand that voters be allowed to physically handle and deposit their own VVPAT slip into a ballot box.
Symbol Loading Units Must Be Sealed and Stored for 45 Days
The Court directed that, after symbols are loaded into VVPAT units, the Symbol Loading Units (SLUs) be sealed and secured in a container in the presence of candidates or their representatives, with these containers stored in a strong room along with the EVMs for a minimum of 45 days following the declaration of results.
Candidates Can Seek Post-Result Verification of EVM Microcontrollers
The Court created a new mechanism: candidates who secure the second or third highest votes in a constituency can, on written request within a specified period and upon payment of a prescribed fee, seek verification of the burnt-memory/microcontroller chips of a defined percentage of EVMs by a team of engineers — with the fee refundable if tampering is found.
Relevant Legal Framework
EVM and VVPAT litigation sits at the intersection of constitutional guarantees on free and fair elections, the core electoral statute, and the technical rules governing how machines are manufactured, sealed and audited.
| Constitution of India, Article 324 | Vests superintendence, direction and control of elections in the Election Commission of India, the constitutional basis for the ECI's authority over how EVMs and VVPATs are deployed and verified. |
|---|---|
| Representation of the People Act, 1951 | Governs the conduct of elections, including provisions on counting of votes and the framework within which VVPAT verification procedures operate. |
| Conduct of Election Rules, 1961 | Sets out detailed procedural rules for polling and counting, including the specific mechanics of VVPAT slip counting that were at issue in this litigation. |
| Election Commission's Technical & Standing Committee Guidelines | Govern manufacturing standards, one-time-programmable microcontrollers, sealing procedures, and random sample verification protocols for EVMs — extensively examined by the Court in this case. |
| Article 141 of the Constitution | Makes the Supreme Court's ruling binding on all courts, meaning the settled position rejecting 100% VVPAT counting governs subsequent litigation on the same core question, subject to review or a future larger bench reconsidering it. |
Timeline of Important Court Proceedings
VVPAT Introduced and Progressively Expanded
Following an earlier Supreme Court direction, VVPAT units begin to be introduced alongside EVMs, reaching 100% coverage across all constituencies by the 2019 general elections.
Sample Verification Expanded to 5 Polling Stations
Following an earlier Supreme Court order, the Election Commission expands VVPAT slip counting from one to five randomly selected polling stations per Assembly constituency, the sample size later challenged as inadequate in the present case.
Hearings Resume Ahead of the 2024 Lok Sabha Elections
A Bench of Justices Sanjiv Khanna and Dipankar Datta resumes hearing the petitions filed by ADR and others, questioning the Election Commission in detail on the technical workings and security features of EVMs and VVPATs.
Verdict Reserved, Technical Clarifications Sought
The Bench reserves its verdict, but relists the matter to seek further technical clarifications from the Election Commission, which confirms 41,629 instances of random verification with over four crore VVPAT slips matched without a single mismatch.
Final Judgment Delivered
The Court delivers its verdict, rejecting 100% VVPAT-EVM cross-verification, direct voter handling of slips, and a return to paper ballots, while directing SLU sealing and creating the candidate verification mechanism.
Review Petition Filed
Petitioner Arun Kumar Agrawal files a review petition challenging the 26 April judgment, raising concerns about the feasibility of full VVPAT counting and the vulnerability of Symbol Loading Units.
Review Petition Dismissed
The same Bench dismisses the review petition, finding no case for review of the 26 April 2024 judgment made out.
Compliance and Verification-Protocol Litigation
Candidates who placed second or third in various constituencies approach the Court seeking a clear, enforceable protocol for the verification mechanism created in 2024; the Court directs the Election Commission to respond and to preserve EVM data pending verification.
What Does This Judgment Mean in Practice?
For Voters
Voting continues to be conducted using EVMs with VVPAT, with no change to how you cast your vote. You can see your vote reflected on the VVPAT screen for a few seconds as before, but you cannot handle or deposit the paper slip yourself — that remains a mechanical, automated process.
For Candidates
If you place second or third in your constituency and have genuine concerns about specific EVMs, you now have a defined, though fee-based, route to request technical verification of the machines' microcontroller chips after results are declared — but this is a post-result verification tool, not a mechanism to seek 100% recounting.
For Political Parties
Parties' representatives are entitled to be present when Symbol Loading Units are sealed after symbol loading, adding a layer of transparency to a part of the process that had previously drawn scrutiny; parties should ensure their booth-level and counting agents are aware of and exercise this right.
For Election Petitioners
Separate from this constitutional ruling, individual election petitions alleging specific instances of EVM tampering or irregularities in a particular constituency continue to be litigated on their own facts before the relevant High Court, and are not foreclosed by this judgment's rejection of the general, system-wide reliefs sought.
Guidance for Candidates and for Voters / Civil Society
This judgment affects different groups differently — from candidates seeking to verify a close result, to voters and civil society organisations concerned about electoral transparency generally. What is useful to you depends on which situation applies.
If You Are a Candidate Seeking EVM Verification
- Confirm whether you placed second or third in your constituency's results, since the Court's verification mechanism is specifically available to candidates in these positions.
- Submit your written request for microcontroller/burnt-memory verification to the Election Commission within the prescribed time window after results are declared, along with the required fee.
- Keep detailed records of any specific irregularities you observed during polling or counting, since these can support both an EVM verification request and, if warranted, a separate election petition.
- If the Election Commission does not respond to your verification request in a timely or transparent manner, consult a lawyer about seeking judicial directions to enforce compliance with the 2024 judgment.
- Understand that this mechanism verifies the integrity of the machine's microcontroller — it is not, by itself, a full recount, and a favourable verification result does not automatically entitle you to challenge the declared result.
If You Are a Voter, NGO or Civil Society Organisation
- Understand that the core legal position — rejecting 100% VVPAT counting and a return to paper ballots — is settled law following the Supreme Court's dismissal of the review petition, and further litigation on this exact question is unlikely to succeed without new grounds.
- If you have concerns about a specific election's conduct, focus on gathering concrete, constituency-specific evidence rather than general system-wide objections, since courts have shown limited patience for repetitive, unsubstantiated tampering claims.
- Engage with the Election Commission's public disclosures on VVPAT verification statistics and SLU sealing compliance to understand how the safeguards are functioning in practice.
- If you believe the candidate verification mechanism itself is not being implemented transparently by the Election Commission, consider whether a public interest litigation on implementation (rather than reopening the settled core question) may be an appropriate route, and consult a lawyer.
Does This Judgment Apply to Your Situation?
The Court's ruling settles the general constitutional question on EVM-VVPAT verification; how it interacts with your specific situation can depend on your role (candidate, voter, party) and whether your concern is about the system generally or a specific election's conduct.
