new delhi, Oct. 19 -- At the Delhi Technological University (DTU)'s east Delhi campus on Sunday afternoon, 48-year-old Ram Dev Prasad sat with a bundle of documents, waiting his turn at a Special Intensive Revision (SIR) camp. His name had been dropped from the electoral rolls after a Booth Level Officer (BLO) visited his brother's address -- the address on all his documents. Prasad is among the 4.7 million people whose names were removed from the draft rolls and are now lining up at camps on two back-to-back Sundays (October 18 and 25) to help eligible voters check their names in the draft electoral roll and submit claims or objections before the October 30 deadline. "All my documents have my brother's address on them, however, due to a rift in the family we don't live together. So, when the BLO visited his house, my elder brother simply said that I don't reside there. That's how my name was dropped," said Prasad. On Sunday, HT visited three camps - two in east Delhi and one in south Delhi - where hundreds of people described difficulties ranging from rejected online applications to names being deleted because officials could not verify their addresses. In Ambedkar Camp, an authorised colony with a predominantly migrant-worker population, around 431 notices were issued in the area, officials said. Munesh Kumar, 36, a government schoolteacher and BLO, said many residents were migrant workers, mostly men whose families lived in villages in Bihar and Uttar Pradesh. They were often away at work when verification visits took place, he said. "I am in school between 12.30pm to 6.30pm so managing the SIR work is challenging," Kumar added. While the east Delhi camps saw relatively low turnout, around 30 people visited the camp in Pillanji Village, Sarojini Nagar, over two hours. According to the Delhi chief electoral officer's October 18 bulletin, 235,351 Form 6 applications seeking inclusion were received between August 31 and October 17, taking the cumulative total to 447,751. During the same period, authorities received 13,773 Form 7 applications seeking deletion of names and 89,577 Form 8 applications for corrections....
