The Bihar Assembly witnessed disruptions for the second consecutive day as opposition legislators protested the ongoing Special Intensive Revision (SIR) of electoral rolls across the state. Dressed in black, MLAs from the Rashtriya Janata Dal (RJD), Congress, and Left parties gathered at the main entrance of the Assembly, raising slogans against what they termed "vote theft" by the Nitish Kumar-led NDA government.

The opposition alleges that the SIR is a scheme to wrongfully delete names of voters unlikely to support the ruling NDA coalition. They claim that the names of lakhs of voters, mostly from poor communities, are being removed. Bihar Congress President Rajesh Kumar stated that they cannot allow the government to run the House while it is allegedly taking away the voting rights of the people. Similar concerns were voiced by Shakeel Ahmad Khan, an MLA from Kadwa in Katihar, and other opposition leaders. The All India Majlis-e-Ittehadul Muslimeen (AIMIM) also joined the protest, with its lone MLA and State president Akhtarul Iman declaring that the SIR would be the "nail in the coffin" for the Nitish Kumar government in the upcoming Assembly elections.

The protests led to multiple adjournments of the House. On Tuesday, proceedings were initially adjourned until lunch after the opposition's uproar. Upon reassembling, Leader of the Opposition Tejashwi Yadav demanded an immediate discussion on the SIR, which the Speaker did not agree to. This refusal further infuriated opposition members, leading to more slogans and some members storming the well, attempting to overturn furniture. Speaker Nand Kishore Yadav expressed exasperation, urging members not to cause injury to staff and warning that their behavior was being televised and would not improve their popularity ahead of the elections. Some opposition MLAs were also seen jostling with marshals who attempted to remove their placards.

Outside the Assembly, the opposition staged demonstrations, declaring they would not allow proceedings to continue until a discussion on the SIR was held. Opposition leaders also took their protest to Parliament in New Delhi, raising slogans and holding placards with messages such as "SIR is a death of democracy". Rahul Gandhi and Priyanka Gandhi were among those participating in the demonstrations.

In response to the allegations, the Election Commission of India (ECI) has defended the SIR, asserting that it is an inclusive, pan-India exercise aimed at removing ineligible voters and strengthening the integrity of elections. The ECI clarified that exclusion from the voter list does not impact citizenship. The BJP has also defended the ECI, stating that the commission is adhering to the constitution and acting in the country's interest. The ECI stated that enumeration forms had been collected from 71,172,660 out of 78,969,844 electors in Bihar, marking a 90.12% completion rate as of July 18, 2025. The ECI also noted that Aadhaar numbers may be voluntarily furnished in the enumeration forms distributed under the SIR order.
