PATNA — A few days ago, India's Election Commission released updated draft electoral rolls for Bihar state, where key elections are scheduled for November, following a month-long revision of the voters' list.

But opposition parties and election charities say the exercise was rushed through — and many voters in Bihar have told the BBC that the draft rolls have wrong photos and include dead people.

The Special Intensive Revision — better known by its acronym SIR — was held from 25 June to 26 July and the commission said its officials visited each of the state's listed 78.9 million voters to verify their details. It said the last such revision was in 2003 and an update was necessary.

The new draft rolls have 72.4 million names — 6.5 million fewer than before. The commission says deletions include 2.2 million dead, 700,000 enrolled more than once and 3.6 million who have migrated from the state.

Corrections are open until 1 September, with over 165,000 applications received. A similar review will be conducted nationwide to verify nearly a billion voters.

But opposition parties have accused the commission of dropping many voters — especially Muslims who make up a sizeable chunk of the population in four border districts — to aid Prime Minister Narendra Modi's Bharatiya Janata Party (BJP) in the upcoming state election.

The poll body and BJP have denied the allegations. In response to the BBC's questions, the Election Commission shared its 24 June order on conducting the SIR and a 27 July press note outlining efforts to ensure no eligible voter was "left behind".

"Further, [the commission] does not take any responsibility of any other misinformation or unsubstantiated allegations being floated around by some vested interests," it added in the response.

The commission has not released the list of deleted names or given any break-up according to religion, so it's not possible to verify the opposition's concerns.

A review by Hindustan Times newspaper found high voter deletions in Kishanganj, a district with the largest share of Muslims in Bihar, but not in other Muslim-dominated constituencies.

Parliament has faced repeated adjournments as opposition MPs demand a debate on what they call a threat to democracy. Outside, they chanted "Down down Modi", "Take SIR back" and "Stop stealing votes". The Supreme Court is also reviewing the move after watchdog ADR questioned its timing.

"It comes just three months before the assembly elections and there has not been enough time given to the exercise," Jagdeep Chhokar of ADR, told the BBC.

"As reports from the ground showed, there were irregularities when the exercise was being conducted and the process of data collection was massively faulty," he added.

The ADR has argued in court that the exercise "will disenfranchise millions of genuine voters" in a state that's one of India's poorest and is home to "a large number of marginalised communities".

It says the SIR shifts the burden onto people to prove their citizenship, often requiring their own and their parents' documents within a short deadline — an impossible task for millions of poor migrant workers.

While the draft roll was being published, BBC travelled to Patna and nearby villages to hear what voters think of SIR.

In Danara village, home to the poorest of the poor known as Mahadalits, most residents work on farms of upper-castes or are unemployed.

Homes are crumbling, open drains line the narrow lanes and a stagnant puddle near the local temple has turned brackish.

Most residents had little to no idea about SIR or its impact, and many weren't sure if officials had even visited their homes.

But they deeply value their vote. "Losing it would be devastating," says Rekha Devi. "It will push us further into poverty."

In Kharika village, many men said they'd heard of SIR and submitted forms, spending 300 rupees (£3.42; £2.55) on getting new photos taken. But after the draft rolls came out, farmer and retired teacher Tarkeshwar Singh called it "a mess". He shared pages showing his family's details — pointing out errors, including the wrong photo next to his name.

"I have no idea whose photo it is," he says, adding that his wife Suryakala Devi and son Rajeev also have wrong pictures. "But the worst is my other son Ajeev's case — it has an unknown woman's photo."

Singh goes on to list other anomalies — in his daughter-in-law Juhi Kumari's document, he's named as husband in place of his son. Another daughter-in-law, Sangeeta Singh, is listed twice from the same address — only one has her correct photo and date of birth.

Many of his relatives and neighbours, he says, have similar complaints. He points out the name of a cousin who died more than five years back but still figures on the list — and at least two names that appear twice.

"There's obviously been no checking. The list has dead people and duplicates and many who did not even fill the form. This is a misuse of government machinery and billions of rupees that have been spent on this exercise."

Chhokar of ADR says they will raise these issues in the Supreme Court this week. In July, the court said it would stay the exercise if petitioners produce 15 genuine voters missing from the draft rolls.

"But how do we do that since the commission has not provided a list of the 6.5 million names that have been removed?" he asks.

Chhokar says a justice on the two-judge bench suggested delinking the exercise from upcoming elections to allow more time for a proper review.

"I'll be happy with that takeaway," he says.

The SIR and draft rolls have split Bihar's parties: the opposition Rashtriya Janata Dal (RJD) questions them, while the ruling Janata Dal (United) — BJP alliance backs them.

"The complexity of this revision has left many people confused," says Shivanand Tiwari, general secretary of the RJD.

Tiwari questions the Election Commission's "claims that 98.3% electors have filled their forms" and says "in most villages, our voters and workers say the Block Level Officer (BLO) — generally a local schoolteacher appointed by the commission to go door-to-door — did not visit them. Many BLOs are not trained and don't know how to upload forms". (The commission has said the BLOs have worked "very responsibly".)

Tiwari alleges that the "commission is partisan and this is manipulation of elections".

"We believe the target are border areas where a lot of Muslims live who never vote for the BJP," he says.

The BJP and the JD(U) have rejected the criticism, saying "it's entirely political".

"Only Indian citizens have the right to vote and we believe that a lot of Rohingya and Bangladeshis have settled in the border areas in recent years. And they have to be weeded out from the list," said Bhim Singh, a BJP MP from Bihar.

"The SIR has nothing to do with anyone's religion and the opposition is raising it because they know they will lose the upcoming election and need a scapegoat to blame for their loss," he added.

JD(U)'s chief spokesperson and state legislator Neeraj Kumar Singh said "the Election Commission is only doing its job".

"There are lots of voters on the list who figure twice or even three times. So shouldn't that be corrected?" he asks. — BBC
