The Election Commission has announced that the voter list in Bihar has been trimmed by 52 lakh voters following an electoral roll revision. The poll body stated that these voters were removed from the list because they were either deceased or had migrated. The Election Commission has assured that "all eligible electors are included in the draft electoral roll to be published on August 1".

This revision, known as the Special Intensive Revision (SIR), is being conducted ahead of the assembly elections in Bihar. The Election Commission has stated that conducting the SIR is its constitutional duty. The commission aims to remove ineligible voters to ensure election purity. According to the commission, multiple reasons, such as rapid urbanization, frequent migration, young citizens becoming eligible to vote, non-reporting of deaths, and the inclusion of names of foreign illegal immigrants, have made this revision necessary.

The Election Commission of India has defended its ongoing Special Intensive Revision (SIR) of electoral rolls in Bihar, stating that it adds to the purity of the election by "weeding out ineligible persons" from the electoral rolls. The poll panel said that an ineligible person has no right to vote.

As of July 18, enumeration forms from 7,11,72,660 electors, constituting 90.12 per cent, had already been collected out of the 7,89,69,844 existing electors in Bihar. The poll panel informed the court that the Form collection phase of the SIR has effectively covered 94.68 per cent of the nearly 7.9 crore-strong electorate in Bihar.

A door-to-door survey, which is part of the Election Commission's Special Intensive Revision (SIR) of Bihar's voter lists, has found many people originally from Nepal, Bangladesh and Myanmar are currently living in the state. Sources said that these people managed to obtain Indian documents such as Aadhaar, domicile certificates and ration cards in their name, apparently through illegal channels.

The opposition has raised questions about the timing of the exercise, arguing that it won't be completed in time for the polls. Allegations have also been made that the Special Intensive Revision was a conspiracy aimed at the willful exclusion of voters. The BJP has countered these claims, questioning why the opposition is concerned if genuine voters are being verified and fake voters are being removed.
