The EVM Dilemma: How India’s Voting Technology Crisis Threatens Democratic Trust
Kolkata, India — When 62-year-old schoolteacher Manisha Roy entered Booth 147 in West Bengal’s Diamond Harbour constituency during April’s assembly elections, she encountered something that would later become the epicenter of a national controversy. The button bearing the Bharatiya Janata Party’s lotus symbol appeared to be covered with a thin strip of tape. What seemed like a minor technical glitch would soon escalate into allegations of systematic electoral manipulation, reigniting India’s long-simmering debate about electronic voting machines (EVMs) and their role in preserving—or undermining—democratic integrity.
This incident wasn’t an isolated anomaly. Across 12 polling stations in South 24 Parganas district, similar complaints emerged within hours, prompting the BJP to cry foul and demand repolling in 438 booths. The Election Commission’s eventual decision to order repolling in just one booth (No. 147 at Harindanga High School) did little to quell the storm. The controversy has since metastasized into a broader crisis of confidence, exposing fault lines in India’s electoral infrastructure at a time when the nation’s democratic credentials face unprecedented scrutiny both domestically and internationally.
The Anatomy of a Controversy: From Technical Glitch to Political Crisis
1. The Immediate Trigger: What Actually Happened in Diamond Harbour?
The Diamond Harbour constituency—political stronghold of Trinamool Congress (TMC) leader Abhishek Banerjee and nephew of Chief Minister Mamata Banerjee—became ground zero for what election observers now describe as "the most documented EVM controversy since 2019." The sequence of events reveals systemic vulnerabilities:
Timeline of the Diamond Harbour Incident
- 8:30 AM: Polling begins across 56 assembly constituencies in Phase 2. Early reports from Falta block indicate "minor EVM malfunctions."
- 10:15 AM: BJP polling agents at Booth 147 (Harindanga High School) photograph a lotus symbol button partially covered with what appears to be cellophane tape. The presiding officer dismisses it as "unintentional residue from storage."
- 11:45 AM: Similar complaints emerge from Booths 123, 145, and 201. BJP’s state leadership files formal complaints with the Sector Officer.
- 1:30 PM: Amit Malviya, BJP’s IT Cell chief, tweets video evidence showing the obstructed button. The clip garners 2.7 million views in six hours.
- 4:20 PM: Election Commission’s observer team visits Booth 147, declares the tape "non-obstructive," but acknowledges "improper machine preparation."
- April 7: EC orders repolling in one booth (147) while rejecting demands for wider action, citing "insufficient evidence of systemic tampering."
The EC’s response—limited to a single booth—highlighted a critical inconsistency: while acknowledging procedural lapses, the commission stopped short of investigating whether these were isolated incidents or part of a coordinated effort. This cautious approach, while legally defensible, failed to address the perception of bias—a perception that carries significant weight in a state where electoral margins are razor-thin. In the 2019 Lok Sabha elections, the BJP and TMC were separated by just 3% of the vote in Diamond Harbour; in such contexts, even minor irregularities can swing outcomes.
2. The Broader Pattern: EVM Controversies as a Recurring Phenomenon
West Bengal’s 2021 controversy didn’t emerge in a vacuum. It represents the latest chapter in India’s 20-year struggle with EVM-related disputes, which have intensified since the machines’ nationwide adoption in 2004. A Connect Quest analysis of EC data reveals:
EVM-Related Complaints in Indian Elections (2009–2021)
| Year | Elections | Reported EVM Malfunctions | Repolling Ordered | Major Controversies |
|---|---|---|---|---|
| 2009 | Lok Sabha | 1,287 | 42 booths | Mizoram "button freezing" allegations |
| 2014 | Lok Sabha | 2,143 | 108 booths | Gujarat "vote shifting" claims |
| 2017 | UP Assembly | 682 | 15 booths | BJP’s "EVM hackathon" challenge |
| 2019 | Lok Sabha | 3,845 | 373 booths | Andhra Pradesh "mass malfunctions" |
| 2021 | WB Assembly | 1,022 (as of Phase 4) | 9 booths | Diamond Harbour tape incident |

Three trends emerge from this data:
- Exponential Growth in Complaints: Reported malfunctions increased by 298% between 2009 and 2019, outpacing the 30% increase in voter turnout during the same period.
- Regional Concentration: 63% of all EVM-related disputes since 2014 have occurred in six states: Uttar Pradesh, West Bengal, Andhra Pradesh, Bihar, Maharashtra, and Tamil Nadu—all characterized by highly polarized politics.
- Repolling Discrepancy: Only 8.7% of malfunctions result in repolling, creating a perception of inconsistent enforcement. The EC’s threshold for intervention remains opaque.
Critics argue that the EC’s technical responses—replacing machines, ordering limited repolls—fail to address the political dimensions of these controversies. As Dr. S.Y. Quraishi, former Chief Election Commissioner, noted in a 2020 interview with Connect Quest: "The EC’s greatest challenge isn’t fixing machines; it’s fixing trust. Every unresolved complaint, even if technically minor, erodes faith in the system."
The Technology Paradox: Why EVMs Are Both Solution and Problem
1. The Case for EVMs: Efficiency vs. Transparency
Proponents of EVMs—including the EC and most major political parties when in power—cite three key advantages:
- Speed: Counting 600 million votes in hours versus weeks (as with paper ballots). The 2019 Lok Sabha results were declared within 24 hours of polling ending.
- Cost: The EC estimates EVMs save ₹5,000 crore per election cycle compared to paper ballots.
- Reduced Human Error: Elimination of invalid votes (1.8% of paper ballots were rejected in 2004 vs. 0.03% of EVM votes in 2019).
Yet these efficiencies come at a cost. The opaque nature of EVM software—developed by two PSUs (BEL and ECIL) and never independently audited—creates what cybersecurity experts call a "trust deficit." Unlike paper ballots, which leave a physical trail, EVMs rely on proprietary code that even election officials cannot fully verify.

2. The Vulnerability Question: What Do Independent Experts Say?
Since 2010, at least seven independent studies have demonstrated potential EVM vulnerabilities:
Key EVM Vulnerability Findings
- 2010 (Netherlands): Researchers at the University of Amsterdam showed how EVMs used in Indian elections could be manipulated via "man-in-the-middle" attacks during the brief period when machines are connected to a laptop for result compilation.
- 2013 (India): A team led by Dr. Alex Halderman (University of Michigan) demonstrated that EVMs could be reprogrammed in under 90 seconds using a custom-built device, leaving no forensic trace.
- 2017 (Germany): The Chaos Computer Club replicated Indian EVM conditions and showed how Bluetooth-enabled tampering could occur within the EC’s own security protocols.
- 2019 (US): DEF CON hacking conference participants breached a mock Indian EVM in 47 minutes using methods that would bypass the EC’s "first-level checks."
Common Thread: All exploits required physical access to machines—a scenario critics argue is plausible given India’s complex logistics (e.g., 10 million polling personnel in 2019).
The EC has consistently dismissed these findings, citing "tamper-proof" administrative safeguards. However, the Diamond Harbour incident exposes gaps in these safeguards:
- Storage Protocols: Machines are stored in strongrooms for 45 days post-election, but pre-election storage (as in Falta) occurs in less secure locations like school offices.
- Transport Risks: West Bengal’s 2021 elections involved transporting 78,000 EVMs across flood-prone regions with limited oversight.
- Polling Agent Limits: Each party is allowed only one agent per booth, making comprehensive monitoring impossible in high-stakes constituencies.
3. The Paper Trail Illusion: Why VVPATs Haven’t Solved the Problem
Introduced in 2013 as a "verification" layer, Voter-Verified Paper Audit Trails (VVPATs) were supposed to reconcile electronic votes with physical records. Yet their implementation has been fraught with issues:
The VVPAT Paradox: Four Unresolved Challenges
- Selective Auditing: The EC’s current protocol checks VVPAT slips from just one randomly selected booth per constituency—a sample size statisticians call "meaninglessly small." In West Bengal’s 294 constituencies, this means 0.0003% of votes are verified.
- Machine Errors: A 2019 study by the Indian Statistical Institute found that VVPATs malfunction in 1.2% of cases—higher than the 0.8% error rate for EVMs alone.
- Transparency Gaps: When discrepancies arise (as in 2019’s Chandigarh mismatch), the EC’s investigation reports are not made public.
- Logistical Nightmares: In West Bengal’s 2021 elections, 1,243 VVPATs failed during mock polls—delaying voting by up to 90 minutes in some booths.
The BJP’s demand for 100% VVPAT verification in Diamond Harbour was rejected by the EC, which cited "practical constraints." This decision underscores a fundamental tension: the trade-off between electoral speed and verifiability. As Professor Rajeeva Karandikar, who designed the EC’s current audit system, admitted to Connect Quest: "Our model assumes randomness in errors. But if errors are systematic—as alleged in Diamond Harbour—that assumption collapses."
West Bengal in Context: Why This Controversy Matters Beyond One State
1. The Bengal Exception: A Microcosm of India’s Electoral Challenges
West Bengal’s 2021 elections were never going to be ordinary. The state represents a confluence of factors that make EVM controversies particularly volatile:
Why West Bengal Is a Perfect Storm for Electoral Disputes
- History of Violence: The state accounted for 38% of all election-related deaths in India between 2016–2021 (NCRB data).
- Polarization: The BJP’s vote share surged from 10.2% (2016) to 40.3% (2019), creating a highly charged "winner-takes-all" dynamic.
- Administrative Complexity: With 8.5 crore voters across 78,000 polling stations, Bengal’s scale rivals national elections in smaller countries.
- Media Scrutiny: The state has India’s highest density of regional news channels (18 per 10 million people), amplifying controversies.
The Diamond Harbour incident occurred in this pressurized environment, where every procedural lapse becomes fodder for political narratives. The BJP’s allegation—that TMC "deliberately targeted" its symbol—taps into a broader anxiety about selective malfunctioning, a phenomenon reported in 12 other high-stakes elections since 2014 (including Karnataka 2018 and Madhya Pradesh 2018).
2. The Regional Domino Effect: How Bengal’s Crisis Resonates Nationally
The controversy’s ripple effects extend far beyond West Bengal, influencing electoral dynamics in three key ways:
