Tamil Nadu has officially commenced the Special Intensive Revision (SIR) of the electoral rolls as a critical part of preparations for the upcoming Assembly elections scheduled for April 2026.
The door-to-door voter list revision exercise started on November 4, 2025, covering all 234 Assembly constituencies with nearly 77,000 election officials including Booth Level Officers (BLOs) participating.
The process involves four stages: From November 4 to December 4, BLOs will distribute and collect partially pre-filled enumeration forms during house visits. The draft voter list will be published on December 9, allowing citizens to file claims and objections until January 8, 2026.
Following investigations and verifications, the final electoral roll is set for release on February 7, 2026. This extensive revision aims to add new voters eligible as of January 1, 2026, remove ineligible or duplicate entries, and maintain an accurate voter database.
However, the revision is facing opposition from the ruling DMK party. Chief Minister M.K. Stalin convened an all-party meeting to discuss his concerns about the SIR process.
The DMK has also filed a petition in the Supreme Court challenging the Election Commission of India’s (ECI) order for the state-wide voter roll revision. The party argues that Tamil Nadu recently completed a Special Summary Revision (SSR) between October 2024 and January 2025, making another exhaustive verification unnecessary.
The petition claims the SIR exercise may lead to mass disenfranchisement and violates constitutional provisions, further questioning the ECIās authority in this matter.The Election Commission maintains that the revision is essential for ensuring the quality and integrity of the voter lists before the 2026 polls, aligning with nationwide efforts in multiple states to update electoral rolls.
Citizens are encouraged to actively participate in the revision process by verifying their voter details, submitting corrections, and providing necessary proofs during the claims period to uphold the democratic process.
