India's opposition took its fight over voter lists to the doors of the Election Commission on Tuesday. Police stopped the march and briefly detained some of its leaders.

Lawmakers marched from parliament toward the commission's headquarters in New Delhi. They demanded that Chief Election Commissioner Gyanesh Kumar resign. Police blocked roads with barricades and hundreds of officers, some in riot gear, Reuters reported.

Police put Rahul Gandhi, the opposition leader in the lower house, his sister Priyanka Vadra and other lawmakers on buses and took them to police stations. They were later released, Congress said. The lawmakers also held a sit-in near the commission, which police ended in the evening, Reuters said. Delhi Police said the detentions were lawful and meant to keep the peace.

"We will sit as long as we have to," Gandhi said. Congress party president Mallikarjun Kharge called the commission "a puppet in the hands of the government." He listed three demands: Kumar's resignation, an end to the voter-list review and a return to paper ballots, the BBC reported.

The fight is over the Special Intensive Revision of voter rolls. It began in Bihar state in June 2025 and has spread nationwide. The commission says it removes duplicate and ineligible voters. More than 130 million names have been cut from draft lists so far, the BBC reported. Critics say many eligible voters were wrongly dropped.

Anger grew after the Indian Express reported that Kumar's two fellow commissioners had objected at least 14 times to orders issued without their knowledge. The commission says decisions were in the end unanimous. Reuters said it could not verify the newspaper's report.

The ruling Bharatiya Janata Party denies the claims. BJP lawmaker Sambit Patra called the protest a "sponsored attempt" to change the government through "anarchy." Kumar has not commented.

The Supreme Court has asked the government and the commission to answer a petition that says Kumar acted without his colleagues. It declined to suspend him for now.

Youth protests are also building. An online satirical movement called the Cockroach Janta Party has held rallies and called for more protests on Oct. 10.

What we know: Opposition leaders were briefly detained, and the court case is moving.
What we don't: Whether the commission will meet the lawmakers or change the review.
