The Congress party has accused the Election Commission of India (ECI) of making arbitrary changes to the Special Intensive Revision (SIR) process for electoral rolls in 12 states. Citing the discontinuation and reintroduction of de-duplication software, the party alleged targeted deletion of voters, particularly in West Bengal and Tamil Nadu, where millions of entries were reportedly unmapped or deleted. Congress demands full transparency and clear instructions for Booth-Level Officers conducting the revision.
