Special Intensive Revision (SIR): Electoral Roll Update Explained

The Special Intensive Revision (SIR) is a door-to-door electoral roll update exercise conducted by the Election Commission of India (ECI) to produce a fresh, error-free voter list. Unlike the routine Summary Revision (where only changes are accepted), SIR requires every existing elector to be re-verified by a Booth Level Officer (BLO) using a new enumeration form supported by documentary evidence.

The ECI launched the first SIR of the decade in Bihar on 24 June 2025 as a pilot, ahead of the Bihar Assembly elections of late 2025. After the Bihar exercise — which drew national debate, opposition protests and a string of Supreme Court hearings — the ECI announced an all-India SIR rollout in 2026, covering all States and Union Territories in phases.

What is Special Intensive Revision (SIR)?

The Election Commission of India prepares and maintains the electoral roll under the Representation of the People Act, 1950. Section 21 of the Act empowers the ECI to direct a revision of the roll “in such manner as it may think fit.” Revisions fall into two broad categories:

SIR is therefore the most comprehensive form of electoral roll update. The last all-India intensive revision was conducted in 2002–2004, making the 2025–26 SIR the first such nationwide exercise in over two decades.

Why ECI Ordered SIR in 2025

The ECI cited four principal reasons:

1. Urban migration and demographic churn — rapid movement of voters between states without deletion from the original roll creating duplicate entries.
2. Inclusion of non-citizens — allegations of foreign nationals, especially in border districts, being enrolled.
3. Deceased voters and "ghost" entries — names of deceased electors not removed by relatives.
4. Shift to address-of-ordinary-residence principle — bringing the roll in line with Section 19 of the RP Act, 1950, which requires the voter to be ordinarily resident in the constituency.

Legal Basis

• Article 324 — ECI's superintendence, direction and control of elections and preparation of electoral rolls
• Article 325 — one general electoral roll per constituency (no discrimination by religion/race/caste/sex)
• Article 326 — universal adult suffrage (age 18+)
• Representation of the People Act, 1950 — Section 21 — ECI's power to direct revision of rolls
• Registration of Electors Rules, 1960 — procedural framework; defines forms (Form 6, 6A, 7, 8)

The SIR Process: Step by Step

Step 1: Pre-Revision Preparation

• Publication of the existing draft roll
• Training of Booth Level Officers (BLOs) (usually schoolteachers or anganwadi workers)
• Appointment of Electoral Registration Officers (EROs) at the constituency level

Step 2: House-to-House Enumeration

BLOs visit every household with a pre-filled Enumeration Form. Each elector must:

• Verify existing entry
• Submit documentary proof of citizenship (one of: passport, birth certificate, matriculation certificate, domicile certificate, Scheduled Caste/Tribe certificate, forest rights record, or — where pre-2003 roll exists — a reference to it)
• Sign the form; BLO attests

Step 3: Filing of Forms

During SIR, every continuing voter effectively re-submits a verification and, where necessary, a corrected Form 8.

Step 4: Draft Roll Publication

The ERO publishes the draft electoral roll in each polling booth area. This is made available physically at BLO offices and online on the ECI voter portal.

Step 5: Claims and Objections Window

A period of 30 days (extendable) is given for:

• Claims for inclusion (Form 6)
• Objections against inclusion of a name (Form 7)
• Corrections (Form 8)

Step 6: Final Publication

After disposal of all claims and objections by the ERO — with appeals available to the District Magistrate and the Chief Electoral Officer — the final electoral roll is published.

SIR in Bihar — The 2025 Pilot

Key facts:

• Order date: 24 June 2025
• Draft roll date: 1 August 2025
• Final publication: 30 September 2025 (ahead of Oct–Nov 2025 polls)
• Pre-SIR roll size: ~7.89 crore electors
• Post-SIR roll size: ~7.24 crore electors
• Net deletions: ~65 lakh names (duplicates, deceased, shifted, non-citizens)

The Bihar SIR accepted the 2003 electoral roll as the baseline — any voter whose name appeared in that roll was presumed to be a citizen and required only residence verification, not citizenship documents.

Controversies and Supreme Court Hearings

The Bihar SIR triggered significant political and legal contestation:

1. Disenfranchisement concerns — opposition parties (RJD, Congress, CPI(ML)) alleged that the citizenship documentation requirement would exclude the poor, migrants, minorities and women who lack formal documents.
2. Aadhaar exclusion — Aadhaar was initially not accepted as proof of citizenship (Aadhaar is proof of residency, not citizenship). After petitions, the Supreme Court directed ECI to consider Aadhaar as one of the acceptable documents in October 2025.
3. Short timeline — 30-day objection window was argued to be insufficient.
4. PILs filed — Association for Democratic Reforms (ADR), Yogendra Yadav, and several political parties approached the Supreme Court. A bench headed by Justice Surya Kant issued multiple directions on:

• Publishing booth-wise lists of deletions
• Giving additional time for claims
• Accepting Aadhaar and ration card as supplementary documents

1. ECI's response — the Commission defended SIR as its constitutional duty under Article 324 to maintain a pure electoral roll, citing precedent of the 2002–04 intensive revision.

All-India SIR Rollout — 2026

On 28 October 2025, following the Bihar experience, the ECI announced SIR across all 28 states and 8 UTs, in three phases ending before the 2026 Assembly polls in West Bengal, Tamil Nadu, Kerala, Assam and Puducherry. Revised safeguards included:

• Baseline roll of 2003 for states with one, or earliest available intensive revision thereafter
• Expanded document list (11 categories, including Aadhaar)
• 45-day claims and objections window
• Automated duplicate detection using ERONET 2.0 software
• Mandatory publication of deletion lists at booth level
• Social audit in sample booths

SIR vs Summary Revision

Significance

• Strengthens Article 326 — ensures only eligible citizens vote
• Plugs inflation in electoral rolls that distorts turnout and seat-share analysis
• Deepens federal cooperation — state administrative machinery is deputed to ECI
• Enables EPIC-Aadhaar linkage data hygiene as part of the 2021 RP (Amendment) Act reforms

Concerns

• Risk of exclusion errors outweighing inclusion errors
• Burden on poor and migrant voters to produce documentation
• Political timing close to elections invites allegations of partisanship
• Digital exclusion where online submission of forms is emphasised
