EVM-VVPAT verification case
Also called: Association for Democratic Reforms v. Election Commission of India (2024) · Topic: Electoral Reforms: Money, Criminalisation and Simultaneous Elections · NCERT: Beyond NCERT
Meaning
The EVM-VVPAT verification case, Association for Democratic Reforms (ADR) v. Election Commission of India (26 April 2024), is the Supreme Court judgment that refused to bring back paper ballots or count 100% of VVPAT slips. Instead, it gave two new checks: symbol loading units must be sealed and stored for 45 days after results, and the 2nd- or 3rd-placed candidate can ask for a check of the burnt memory of 5% of EVMs in each assembly segment [1]. It matters because it is the latest step in India's answer to one question: how can voters trust a machine they cannot see inside? The Court's answer was more checks inside the EVM system, not a return to paper.
Explanation
What the Court rejected
- The bench of Justices Sanjiv Khanna and Dipankar Datta wrote separate judgments that agreed with each other [1].
- It said no to three demands [1]:
- a return to paper ballots, which the Court called "a folly"
- counting 100% of VVPAT slips
-
handing the slip to the voter to keep or drop in a box
-
Why:
- Article 19(1)(a) (freedom of speech and expression) includes the voter's right to know that the vote was counted as cast [1].
- The voter already gets this right by seeing the slip for 7 seconds behind the glass window [1].
-
There is no fundamental right to 100% VVPAT tallying [1].
-
Justice Datta warned that "blindly distrusting any aspect of the system can breed unwarranted scepticism and impede progress" [1].
Direction (a): seal the symbol loading units (SLUs)
- SLU: a small device that loads the candidates' serial numbers, names and symbols into the VVPAT. It cannot change the program burnt into the chip [1].
-
The steps: 1. It applies to symbol loading done on or after 1 May 2024 [1]. 2. After loading, SLUs are sealed in containers, and candidates sign the seals [1]. 3. They are kept in the strong room with the EVMs for at least 45 days after results [1].
-
Why 45 days:
- An election petition (a case filed in a High Court to challenge a result) must be filed within 45 days of the result [1][2].
- So the SLUs stay safe for as long as a court challenge can still be started.
Direction (b): check the burnt memory
- Burnt memory: the microcontroller, which is the chip holding the machine's fixed program. The program is "burnt" in once and cannot be rewritten.
- The steps, in order: 1. Who can ask: only candidates placed 2nd or 3rd [1]. 2. Time limit: a written request within 7 days of the result [1]. 3. What is checked: 5% of EVMs in each assembly segment. This covers the control unit, ballot unit and VVPAT. The candidate picks the machines by polling station or serial number [1]. 4. Who checks: engineers from the manufacturers (BEL and ECIL) [1]. 5. Who certifies: the District Election Officer confirms whether the memory is intact [1]. 6. Cost: the candidate pays. The money is refunded if tampering is found [1].
Limits: what the Court only suggested
- The Court left two ideas to the ECI and did not order them [1]:
- counting slips by machine
-
printing barcodes on slips so that machines can count them
-
The burnt-memory check happens after the result. It does not change how votes are counted on counting day.
In the Constitution and practice
- Legal base of EVMs: Section 61A, Representation of the People Act, 1951, was inserted by Act 1 of 1989 after EVM use without a law was challenged in court [1]. The detailed rules are in the Conduct of Election Rules, 1961 (rr. 49A–49X on machine voting, r. 56D on counting VVPAT slips).
- Constitutional anchors:
- Article 19(1)(a): the voter's right to know the vote was recorded correctly [1].
-
Article 324: gives the ECI superintendence, direction and control of elections. The Court did not second-guess the ECI's technical choices without evidence.
-
How the case law built up, in three steps:
- Subramanian Swamy v. ECI (2013): a paper trail is an "indispensable requirement of free and fair elections". VVPAT could come in phases, paid for by the Union [1]. VVPAT was in use everywhere by 2019.
- N. Chandrababu Naidu v. Union of India (2019): slip counting rose from 1 to 5 random EVMs per assembly segment. Opposition parties had asked for 50% [1].
-
ADR v. ECI (2024), 2024 INSC 341: no 100% count, but SLU sealing and burnt-memory checks were added [1].
-
Record placed before the Court:
- VVPAT slips from 41,629 EVM-VVPATs, more than 4 crore slips in all, had been matched with the electronic counts.
- Only one mismatch was found, and it was explained [1].
- Of 26 Rule 49MA complaints (a voter saying the slip showed the wrong candidate), none was found true [1].
-
The ECI also said EVM totals had matched Form 17C data [1].
-
Safeguards the Court relied on:
- only two public sector firms make EVMs (BEL and ECIL)
- one-time-programmable chips
- machines that are not networked
- UADM in M3 EVMs, which permanently disables a machine if anyone tries to open it
- a First-Level Check of every machine
- two-stage random allocation of machines
- mock polls
- sealed strong rooms [1][2]
Don't confuse with
- N. Chandrababu Naidu (2019) raised the number of VVPAT slips counted (from 1 to 5 EVMs per segment). ADR (2024) did not change the slip count. It added a burnt-memory check of 5% of EVMs, and only when a losing candidate asks [1].
- Subramanian Swamy (2013) made the paper trail itself compulsory. ADR (2024) dealt with how much checking of that trail and of the machines is needed [1].
- A Rule 56D slip recount is a request to the Returning Officer to count VVPAT slips, and the Returning Officer decides. The ADR burnt-memory check is an engineer's check of the chip, asked for within 7 days of the result and certified by the DEO [1].
- Germany's Federal Constitutional Court (2009) struck down EVMs because ordinary citizens could not check them without expert knowledge (the "public nature of elections"). India's Supreme Court (2024) kept EVMs and added expert-led checks instead.
Prelims Hooks
- ADR v. ECI (26 Apr 2024), bench of Justices Sanjiv Khanna and Dipankar Datta: rejected paper ballots, a 100% VVPAT count and handing slips to voters [1].
- Burnt-memory check: 5% of EVMs per assembly segment, asked for by the 2nd or 3rd-placed candidate within 7 days, at the candidate's own cost and refunded if tampering is found [1].
- Trap: the check is done by manufacturers' engineers (BEL/ECIL), not ECI staff or independent auditors. The District Election Officer certifies the result [1].
- SLUs are sealed for at least 45 days after results, for symbol loading on or after 1 May 2024. The 45 days match the deadline for filing an election petition [1][2].
- The voter sees the VVPAT slip for 7 seconds (Rule 49M(3)). The Court held this satisfies the right to know under Article 19(1)(a) [1].
- Barcoded slips and machine counting were only suggested to the ECI, not ordered [1].
Mains Points
- Trust vs proof:
- More than 4 crore matched slips show the EVM is accurate [1].
- But a democracy needs voters to see fairness, not just be told about it.
-
The ADR checks are triggered after the result and paid for by the candidate. Further steps could build more trust: barcoded slips that machines can count, larger VVPAT samples in close contests, and public release of First-Level Check and randomisation records.
-
Judicial restraint and ECI autonomy (Article 324):
- The Court refused to replace the ECI's technical judgment without evidence of tampering.
- It still added checks after the result.
-
This is a "trust but verify" model of oversight that keeps the EVM system and opens it to challenge.
-
Independence of the audit:
- The machines are checked by engineers of the same firms that made them.
- Critics can therefore ask whether the check is truly independent.
- Following Germany's 2009 public-verifiability test, India could add independent technical audits and publish its source-code review process. This would make the ECI's credibility depend less on court rulings.
