Kolkata: At the stroke of midnight on April 6, the Election Commission of India’s (ECI) publication of the 12th and final supplementary voter list brought the Special Intensive Revision (SIR) process in West Bengal to a hard bureaucratic close.

The rolls now stand frozen for the assembly election scheduled later this month, ending the revision exercise with nearly 89 lakh fewer voters on the list than when the revision process began.

The ECI’s final published district-wise list of voters kept under adjudication is significant not because it settles the controversy, but because it lays bare the brutal math behind this historic shrinkage. For the first time, the public can see the district-level numbers showing how many were reinstated after the judicial review, and how many were summarily purged.

Set against the broader pre-revision numbers, the total electorate has been slashed by 11.61%. As the state heads to the polls, an analysis of the final published list reveals a troubling picture of systemic, administrative disenfranchisement.

Here are five analytical takeaways from the data.

1. The scale of exclusion 

The final figures show that this was not a minor correction of outdated entries or a standard roll purification. More than 60 lakh voters were pushed through a rapid adjudication process, resulting in the direct disqualification of over 27 lakh citizens. The overall roll contracted by nearly 89 lakh names between the pre-SIR stage and the midnight freeze.

That alone makes this one of the most consequential and severe, electoral filtering exercises in recent memory. The concern is not merely the size of the operation, but the timing of the transparency as well. District-level numbers have come into public view only after the process is effectively over. By the time this data was released to the public, the list had been frozen, and the electoral consequences were already locked.

The adjudication guillotine sees a 78% strike rate in Nadia

While the statewide average of deletion during the adjudication phase stands at a severe 45.22% (27,16,393 voters deleted out of 60,06,675 examined), the district-wise strike rate exposes an even harsher administrative reality. In certain districts, being flagged for adjudication has almost a guaranteed ticket to disenfranchisement.

Nadia district experienced an astonishing 77.86% deletion rate under adjudication, where 2,08,626 of the 2,67,940 flagged voters were marked ineligible.

Hooghly was not far behind with a 70.33% deletion rate (1,20,813 deleted out of 1,71,778).

Kolkata North saw 63.96% of its adjudicated voters struck down, while Purba Bardhaman and North 24 Parganas registered deletion rates of 57.40% (2,09,805 deleted) and 55.08% (3,25,666 deleted), respectively.

The purge disproportionately targets Muslim and Matua strongholds

The geographical breakdown of the purged data exposes a stark demographic concentration. This suggests the ECI’s process disproportionately impacted specific communities and border regions.

The highest volume of deletions in the judicial review of the under adjudicated voters occurred in Murshidabad, the district with the highest Muslim population in the state, where an astonishing 4.55 lakh voters were rendered ineligible. This pattern continues across minority-heavy border districts. Maldah saw 3.25 lakh names dropped, followed by South 24 Parganas (2.22 lakh), Nadia (2.08 lakh), and Uttar Dinajpur (1.76 lakh).

Looking at the total roll shrinkage, Murshidabad lost a staggering 7.44 lakh voters, Maldah dropped by 4.53 lakh, and Uttar Dinajpur shrank by 3.63 lakh.

Equally impacted are the core regions of the Matua community, a marginalised group historically vulnerable to citizenship and documentation disputes. North 24 Parganas and Nadia, the primary epicentres of the Matua vote, faced a relentless culling. North 24 Parganas suffered the highest overall district deletion in the state, with a massive 12.38 lakh voters wiped from the pre-SIR rolls. Nadia similarly lost 4.82 lakh overall.

4. Wiping out the transient workforce

While rural and border districts saw the highest absolute numbers of deleted voters, an analysis of the highest percentage deletions reveals a systematic purge of the urban and industrial belts. This exposes how the ECI’s mapping process severely penalised transient populations including urban renters, out-of-state migrant workers, and daily wage labourers who shift residences frequently for employment.

Kolkata North experienced the highest proportional wipeout in the state, losing an astonishing 28.97% of its pre-SIR electorate (4.36 lakh voters). Kolkata South was close behind, shrinking by 27.31% (2.47 lakh voters). In the industrial and mining heartlands, the story is equally grim. Paschim Bardhaman, home to the Asansol-Durgapur industrial belt and a massive migrant workforce, saw a 16.44% reduction (3.82 lakh voters deleted). Howrah, another major industrial hub, lost 14.33% of its voters, amounting to an absolute deletion of 5.93 lakh citizens.

5. The skew of two phases and unequal weights

The concentration of these deletions is both demographic and heavily electoral. 

The 15 districts going to polls in the first phase on April 23, account for 39.57 lakh deletions across 152 seats. Among these Phase 1 districts, the heaviest overall reductions are concentrated in minority dominated Murshidabad (7.44 lakh), Maldah (4.53 lakh), Uttar Dinajpur (3.63 lakh), and Hindi-speaking, migrant worker-dominated industrial Paschim Bardhaman (3.83 lakh).

The eight districts going to the polls in the Phase 2 on April 29, Howrah, Hooghly, Kolkata North, Kolkata South, Nadia, North 24 Parganas, South 24 Parganas, and Purba Bardhaman, account for a massive 49.38 lakh deletions, or 55.5% of the total statewide reduction. Yet, these districts account for 142 of the state’s 294 seats.

One of the most revealing aspects of the final list is that formal adjudication does not entirely explain the scale of voter loss. The ECI is yet to publish assembly-level data. District-level analysis indicates that initial “unmapping” tracks total deletion much more closely than the final adjudication outcome does. In simple terms, districts with high unmapping – a lack of connection of a voter to the 2002 rolls – in the draft phase showed high total deletions by the final freeze. 

Officially, the ECI argues that every name was examined and that the 27 lakh citizens found ineligible can still approach judicial tribunals for reconsideration. Formally, under the Supreme Court’s orders, this is true. Yet, the court has declined to grant interim relief to these voters. Despite the state government’s plea for urgent intervention, the court stated, “We do not want to rush it,” estimating that the 19 appellate tribunals could take up to 60 days to dispose of cases. Currently, none of the 19 tribunals are fully functional. They have yet to hear a single appeal from an ordinary citizen, focusing only on two urgent cases involving candidates.

With the deadline for the 152 first-phase constituencies having expired on April 6, and the second-phase deadline ending on April 9, the right to appeal has been rendered moot for the current election. The ECI’s prioritisation of a “clean” list over meaningful electoral access, and the highest court’s approval in this have resulted in a scenario where administrative delay has achieved the same result as a final legal exclusion.
