The Special Intensive Revision (SIR) of electoral rolls, which commenced as a pilot exercise in Bihar on June 24, 2025, has now completed one year and expanded to 19 States and Union Territories across India. Bihar, as the State where the SIR was first implemented ahead of its Assembly elections, occupies a central position in what has become the most contested electoral process reform in India since the introduction of Electronic Voting Machines. Nearly six crore names have been deleted from electoral rolls across the country during the first year of SIR, with Bihar alone seeing approximately 65 lakh voters pruned from its rolls.
The SIR has generated fierce political controversy. Opposition parties — particularly the Samajwadi Party, the Indian National Congress, and the Trinamool Congress — have alleged that the Election Commission of India (ECI) is conducting the SIR in a manner that disproportionately removes Dalit, minority, and economically weaker voters from the rolls, effectively serving as a disenfranchisement tool. The Supreme Court, in March 2026, unanimously upheld the constitutional validity of the ECI’s decision to conduct the SIR. The SIR has now been incorporated into the NCERT’s Social Science textbook, which describes it as ensuring ‘no eligible citizen is left out and no ineligible person is included in the electoral roll’. West Bengal and Bihar governments have linked voter roll purification data to social security benefits, excluding individuals deleted during SIR from State welfare schemes — a development that has raised additional constitutional concerns.

Background: Electoral Roll Revision and the SIR Framework
Five Important Key Points
- The SIR commenced as a pilot in Bihar on June 24, 2025, ahead of its Assembly elections; Bihar’s electoral roll was subsequently pruned by approximately 65 lakh voters, reducing the State’s voter base significantly.
- Across 19 States and Union Territories in the second phase (UP, West Bengal, Tamil Nadu, Rajasthan, Chhattisgarh, Kerala, and others), the combined voters’ list was pruned from 50.99 crore to 45.81 crore — a reduction of over 5.18 crore.
- The Supreme Court unanimously upheld the constitutional validity of the ECI’s SIR exercise in March 2026, rejecting petitions that challenged it as a violation of the fundamental right to vote.
- Bihar and West Bengal governments have linked voter roll purification data to social security benefits, making deletion from the electoral roll a potential trigger for exclusion from State welfare schemes — a policy with significant constitutional implications under Article 21.
- The SIR has been incorporated into NCERT’s Social Science curriculum, reflecting the government’s effort to mainstream the exercise as a civic normalcy rather than a contested political process.
Historical and Legal Background
Electoral roll revision in India is governed by the Representation of the People Act, 1950 (which deals with the preparation and revision of electoral rolls) and the Registration of Electors Rules, 1960. The Election Commission of India, under Article 324 of the Constitution, has superintendence, direction, and control of the preparation, maintenance, and revision of electoral rolls and the conduct of elections. The ECI conducts four types of roll revision: continuous, intensive, special intensive, and summary revision. A Special Intensive Revision involves house-to-house survey, re-enumeration of eligible voters, and deletion of names of deceased, those who have migrated, or those who are otherwise ineligible.
The SIR’s context includes the citizenship controversy that has surrounded the National Register of Citizens (NRC) process in Assam and the broader debates about the National Population Register (NPR). Critics have drawn parallels between the SIR’s roll-purification methodology and Assam’s NRC process, arguing that both place the burden of proving citizenship/eligibility on individuals, potentially excluding genuine voters who lack documentation.
Bihar-Specific Analysis
Bihar’s experience as the SIR’s pilot State is foundational for understanding the exercise’s operational and political dynamics. The State’s 65 lakh voter deletion — representing approximately 9 percent of its voter base — was the largest absolute reduction in any State. The deletions were concentrated in urban areas (where migration is higher) and in districts with significant Muslim populations — particularly Seemanchal (Araria, Purnia, Kishanganj, Katihar) — leading to allegations that the process was being used for discriminatory targeting.
Bihar’s political context amplifies these concerns. The State has a fragile coalition government (NDA), with JD(U) under Chief Minister Nitish Kumar maintaining a delicate balance between the BJP’s Hindutva-inflected electoral strategy and the State’s socially diverse electorate. The SIR, in Bihar’s political landscape, intersects with caste identity, Muslim representation, and the rivalry between the NDA and the Tejashwi Yadav-led Mahagathbandhan (Grand Alliance) which represents backward and minority communities.
The linkage of voter deletion to social security benefits is particularly significant in Bihar. Bihar has some of India’s highest rates of poverty and dependence on government welfare — MGNREGA, PM Awas Yojana, PM Kisan, ration cards, and state pensions. Removing individuals from welfare eligibility based on electoral roll deletion effectively converts electoral disenfranchisement into social exclusion — a compounding form of marginalisation that disproportionately affects Bihar’s most vulnerable communities.
Constitutional Provisions and Supreme Court Judgment
The constitutional framework for electoral rolls is provided by Article 326 (adult suffrage), Article 325 (no voter ineligible on grounds of religion, race, caste, or sex), and Article 324 (ECI’s superintendence over elections). The Representation of the People Act, 1950, Section 15 mandates the preparation of electoral rolls for every constituency, with Section 22-23 dealing with revision and claim/objection processes.
The Supreme Court’s March 2026 judgment upholding the SIR’s constitutional validity relied on the ECI’s constitutional mandate under Article 324 to maintain clean electoral rolls. The Court held that the SIR’s objective — ensuring no eligible citizen is left out and no ineligible person is included — serves the constitutional purpose of free and fair elections. However, the Court did not specifically rule on the due process concerns raised by petitioners regarding the speed of deletions and the adequacy of notice periods given to voters whose names were proposed for deletion.
NCERT and Mainstreaming of SIR
The inclusion of SIR in NCERT’s Social Science textbook is a significant development that deserves scrutiny. Textbooks shape civic consciousness and inform how future generations understand democratic processes. The description of SIR as an exercise to ‘ensure no eligible citizen is left out and no ineligible person is included’ presents the exercise in its most benign form, without acknowledging the contested political and procedural questions it has raised. Critical pedagogy would require students to understand the arguments both for and against the SIR’s methodology, the Supreme Court’s nuanced judgment, and the ongoing debates about due process and minority representation.
Way Forward
Electoral roll accuracy is a genuine democratic necessity — rolls bloated with phantom voters or depleted by systematic exclusion both undermine electoral integrity. A reformed SIR framework should incorporate the following safeguards: First, the notice period for proposed deletions should be extended to at least 45 days (from the current 30 days), with notices issued in local languages and through multiple channels (SMS, gram panchayat announcements, school networks). Second, re-inclusion mechanisms should be simple and accessible, allowing deleted voters to restore their names with minimal documentation burden. Third, the linkage of voter roll deletions to social welfare eligibility should be severed — electoral roll status and welfare eligibility are separate legal matters and should not be conflated. Fourth, the ECI should publish ward-wise and demographic category-wise data on deletions, ensuring transparency that allows civil society to monitor for discriminatory patterns. Fifth, a permanent mechanism for continuous roll updation — using the Aadhaar-voter ID linkage, with appropriate privacy protections — should be developed to replace the periodic intensive revision model.
