New Delhi: After Haryana and Andhra Pradesh, Election Commission (EC) Wednesday extended the schedule for the ongoing Special Intensive Revision (SIR) of electoral rolls in Delhi, with the publication of draft and final rolls also pushed back.Door-to-door visits by booth-level officers (BLOs), which were to end on July 29, will continue until Aug 8. The draft rolls, which will now be published on Aug 17 instead of Aug 5, will reveal how many of the electors have been struck off.The period for filing claims and objections will run from Aug 17 to Sept 16, instead of Aug 5 to Sept 4. The deadline for disposal of claims and objections has also been extended from Oct 3 to Oct 15. The final rolls will be published on Oct 19, instead of Oct 7, the original date.The reason behind the extension of the SIR schedule was not officially revealed by the poll panel. Officials, however, said that the additional time will give the BLOs more time for door-to-door verification, collection of pending enumeration forms and completion of digitisation before the draft rolls are published.It will also give voters more time for filling in the forms, which is required to ensure comprehensive verification and minimise the chances of eligible electors being left out of the rolls.Starting from June 30, around 13,000 BLOs have till Wednesday distributed the forms meant for all 1.45 crore registered voters across 70 assembly constituencies of the capital.Data accessed by TOI reveals that voters changing their registered addresses has emerged as the biggest reason why many completed enumeration forms could not be collected. This may also be the reason behind the highest number of deletions when the draft rolls are published.Out of 1.5 lakh forms that could not be collected till July 13, over 1 lakh were meant for people who have permanently shifted residences and risk having their names struck off the rolls. Other reasons include death (26,712), untraceable/absent voters (11,026), duplicate enrolment (7,221) and miscellaneous cases (1,006).TOI has reported that though the enumeration forms have been distributed across the capital, the back-end digitisation process, which shows how many of them have been filled in and returned by people before being successfully mapped by BLOs, remains at an early stage. Just over 17 lakh forms, or around 12% of the electorate, have been digitised so far.Officials cited apathy among voters behind this slow progress. However, they hoped that it would pick up speed from this week because in the first 15 days after the launch of SIR, the primary target was to distribute the forms among the registered voters. “In the next days, we will focus on collecting them,” said an official, adding, “Many people submit forms close to the deadline.”
