What began as a technical exercise to “clean” India’s electoral rolls has morphed into one of the most serious institutional controversies of recent years. By the end of 2025, the Special Intensive Revision (SIR) of electoral rolls had triggered mass exclusions, legal challenges, political outrage and a deeper question: is India quietly rewriting the rules of universal suffrage? The issue has triggered a political storm across the country.
Assam
When Assam published its draft electoral rolls after completing its revision, the numbers stunned observers. Despite deleting 10.56 lakh names of voters who had died or permanently migrated, the state added 10.55 lakh new voters. The final tally remained unchanged at 2.52 crore voters – exactly what it was before the revision.
Assam was the only state among 11 undergoing revision where the controversial SIR framework was not applied. Instead, the Election Commission followed a conventional, rigorous method of door-to-door physical verification, without compulsory enumeration forms or demands for documentary proof of citizenship.
In every other SIR state, the outcome was dramatically different.
Across India, 6.56 crore names were provisionally excluded under the SIR. Tamil Nadu lost 97 lakh voters, Gujarat 73 lakh, West Bengal 58 lakh, and even Goa saw nearly 90,000 deletions. The contrast was so stark that Assam became an accidental control group, a natural experiment exposing the design flaws of the SIR itself.
Two New Rules, One Fatal Design Flaw
The SIR introduced two unprecedented requirements including mandatory enumeration forms and proof of citizenship documents.Neither had been required in earlier revisions.
These rules collided head-on with Indian reality. Millions of Indians, especially the poor, migrants, Adivasis, Dalits, women, and informal workers, do not possess birth certificates, domicile papers, or consistent identity records. The SIR assumed a fully documented citizenry that simply does not exist.
Errors followed predictably: spelling mismatches, incorrect years of birth, missing forms, untranslated names, and software-generated “logical discrepancies” that voters neither understood nor could contest.
Bihar
The crisis first erupted in Bihar. The draft rolls initially dropped 65 lakh names, later reduced to 44 lakh after Supreme Court intervention. Yet even this “corrected” figure masked a deeper problem.
Bihar’s adult population in 2025 was estimated at 8.22 crore. Post-SIR, the final electoral roll stood at 7.45 crore – an exclusion of 77 lakh adults. The gender ratio fell sharply, from 916 women per 1,000 men to 894, indicating that women were disproportionately excluded. Independent analysis also suggested higher deletions among Muslim voters.
Even after the exercise, the rolls were riddled with errors:59 lakh duplicate entries, 75,000 voters withoutaddresses or father’s names, andnames written in Kannada and Tamil in a Hindi-speaking state. None of these anomalies was denied or corrected by the Election Commission.
If the goal was accuracy, Bihar failed. If the goal was inclusion, it failed spectacularly.
Uttar Pradesh
The most damning evidence against the SIR came from Uttar Pradesh.While the ECI conducted SIR for Assembly elections, the State Election Commission of UP simultaneously revised voter lists for panchayat elections, using a simpler, older method without enumeration forms or citizenship proof.
The results could not have been clearer.
UP’s adult population in Dec. 2025 stood at 16.1 crore: Pre-SIR ECI rolls: 15.4 crore; Post-SIR ECI rolls: 12.6 crore; SEC-UP panchayat rolls: 16.1 crore. Two constitutional authorities mapped the same electorate at the same time. One excluded nearly 3.5 crore adults. The other excluded virtually none.The only variable was methodology.
The SIR’s deepest injustice lies in its blindness to undocumented India.In Tamil Nadu,official data admits that nearly one million births at home occurred in 2022–23. Migration figures are even murkier: the 2011 Census estimated 4.14 crore inter-state migrants, while later labour surveys put the number at 29 per cent of the population.For these citizens, the SIR is not a safeguard against fraud; it is a machinery of erasure.
West Bengal
Nowhere has the SIR’s human cost been more visible than in West Bengal. Voters began receiving hearing notices over discrepancies dating back to 2002, when rolls prepared in Bengali were later translated into English. Distorted spellings and inconsistent data entries triggered mass summons.
Among those served notices were Amartya Sen, Mohammed Shami, actors, poets, senior police officers and former ministers. If Nobel laureates and national icons could be flagged for “logical discrepancies,” ordinary voters stood little chance.The process was opaque, the rules kept changing, and many elderly voters described the hearings as intimidating.
It was against this backdrop that Trinamool Congress general secretary Abhishek Banerjee launched one of the sharpest political attacks ECI has faced in decades.After leading a TMC delegation to the ECI in Delhi, Banerjee accused CEC Gyanesh Kumar of presiding over “a systematic theft of votes”.
“This is not a clerical error. This is vote chori,” Banerjee said, alleging that the BJP had stolen electoral mandates in Haryana, Delhi, Bihar and Maharashtra with the active or passive help of the election machinery.
“Congress and AAP couldn’t catch it in Maharashtra, Delhi, Haryana. If they had, the BJP would have lost,” Banerjee said, calling on “like-minded parties” to expose what he described as software-driven manipulation of voter rolls.
Banerjee claimed that during the 2.5-hour meeting, the CEC interrupted repeatedly and “lost his temper.”
“I told him: you are nominated, I am elected,” Banerjee said. “You are answerable to your masters. We are answerable to the people.”
Banerjee demanded the release of CCTV footage of the meeting and accused Kumar of being “sent on a mission to destroy this institution.”
He also demanded that the ECI publish the ‘logical discrepancy list’ used in West Bengal’s SIR.
Transparency, Law and Power
Six months after announcing the SIR, the ECI has still not disclosed: which agency identified the discrepancies, why discarded error-prone software was reused, and how “logical inconsistencies” are defined or applied.
By law, only Electoral Registration Officers can delete names, and only after due notice and opportunity for appeal. Yet in states like West Bengal, system-driven deletions were reportedly carried out en masse, bypassing statutory safeguards.
Supporters of the SIR argue that electoral rolls must be accurate. Few disagree. But accuracy cannot come at the cost of exclusion, nor can it be built on assumptions that erase the undocumented poor.
The natural experiments of Assam and UP point to a simple truth that when voter revision does not shift the burden of proof onto citizens, mass disenfranchisement does not occur.
As the country heads into 2026, the question is no longer whether the SIR is flawed. The evidence is overwhelming. The real question is whether India’s democratic institutions will correct course – or allow a deeply exclusionary system to redefine who gets to vote.
