EC’s expanded logical discrepancy list for third phase of SIR keeps voters on their toes

Why in the News

The Election Commission of India (ECI) has expanded the list of “logical discrepancies” used to flag electors in the third phase of the Special Intensive Revision (SIR) of electoral rolls to up to 11 distinct categories. The categories have been identified and applied across States and Union Territories including Karnataka, Haryana, Delhi and Telangana. The list has grown from the original four categories used when the concept was introduced during West Bengal’s SIR. A flagged elector must prove eligibility to stay on the roll, and the flag is generated by a centralised system rather than by field verification. The contested point is that the term has never been defined in any official communication, so an elector cannot know in advance what will trigger it.

What is a “logical discrepancy” under the SIR?

1. What the term describes: A logical discrepancy is an inconsistency the Commission’s software detects between an elector’s entry and the entries of that elector’s relatives on the base roll.
2. How it is generated: The software attempts “progeny mapping”, linking a voter to their parents’ entries on the base roll, and flags the inconsistencies that result.
3. What a flag does to the elector: A flagged elector receives a notice and must establish eligibility to remain on the roll. A place in the draft list does not prevent the flag.
4. Origin of the category: The category first surfaced during the SIR in West Bengal and was carried into the current phase.

Which categories does the expanded list carry?

1. Sibling age gap: An age gap of less than nine months between siblings is treated as a discrepancy.
2. Parent age gap: An age gap of less than 15 years between a voter and their parent is flagged.
3. Grandparent age gap: An age gap of less than 40 years between a voter and their grandparent is flagged.
4. Sibling count: More than six siblings linked with a single parent is flagged.
5. Parent name variation: A discrepancy or spelling variation in a parent’s name between the current electoral roll and the previous revision is flagged.
6. Relative mapping change: A change in relative mapping between revisions is flagged, such as a father recorded in the previous roll against a mother in the current roll.
7. Marital mapping mismatch: A female voter linked to her father in the previous roll and mapped to her husband in the current roll without cross referencing is flagged.
8. Age progression discrepancy: An implausible age leap, or a mathematical discrepancy between different revision cycles, is flagged.

How does ERONet flag a discrepancy, and who controls it?

1. The flagging system: Discrepancies are flagged under a centralised artificial intelligence system through ERONet, the Electoral Roll Officers’ Network.
2. Centralisation flagged internally: Two Election Commissioners have flagged the ERONet software for having become increasingly centralised.
3. Officers locked out: Electoral Registration Officers (EROs) have complained that they are unable to access the platform from their end in many cases, according to the two Commissioners.

Why has the category never been defined?

1. No definition in any official communication: “Logical discrepancies” has never been clearly defined in any official communication, neither in the Commission’s notice of May 2026 nor in the original SIR order of June 2025.
2. Parameters not documented: The actual parameters and the methodology used to assign an elector to the category were not publicly documented.
3. Effect on the elector: An elector cannot contest a classification whose criteria are unavailable, so the burden of proving eligibility falls on a person who cannot see the test being applied.

What has the Right to Information route produced?

1. A trade secret claim: The Commission was described as “hiding” details of the software on the ground that it was a “trade secret”, by a former Member of Parliament who is a Right to Information (RTI) Act activist.
2. Refusal on commercial grounds: RTI applications seeking details of the software were refused, with the Commission claiming that disclosure would affect “commercial confidence”.
3. The objection recorded: The software was described as an opaque algorithm used to delete voters through a centralised system in Delhi, bypassing the EROs. Software used by a public authority being kept secret for commercial interests was the specific objection raised.

How many electors has the list touched?

1. West Bengal: Approximately 1.36 crore voters received notices when the logical discrepancy category first surfaced during West Bengal’s SIR.
2. Delhi: 19.33 lakh electors have received discrepancy notices in Delhi, where the SIR is being conducted currently.
3. Karnataka: 20.35 lakh electors have received the notices in Karnataka.

Conclusion

The third phase of the SIR is running with an expanded discrepancy list whose criteria the Commission has not published and whose software it has declined to describe. Electors are being asked to rebut a classification they cannot examine, and the officers statutorily responsible for the roll report that they cannot reach the system generating it. The next milestone is whether the Commission publishes the parameters and the methodology behind the category before the phase closes, or whether the classification is settled case by case through the notice and appeal process.
