On December 17, Union Law Minister Arjun Ram Meghwal introduced the Constitutional Amendment Bill in the Lok Sabha for "One Nation, One Election." In response, Congress MP Manish Tewari opposed the bill, arguing that it violates the basic structure of the Indian Constitution. He highlighted that the Constitution's federalism and democratic structure cannot be changed through such amendments, as they are beyond the legislative power of Parliament. Samajwadi Party MP Dharmendra Yadav also opposed the bill, expressing confusion over how the government quickly moved to amend the Constitution after claiming to protect it. He supported Tewari's view and stressed the wisdom of the Constitution's framers, opposing any changes that undermine its core principles.

Union Parliamentary Affairs Minister Kiren Rijiju criticized the opposition, particularly the Congress party, for playing a negative role regarding the One Nation, One Election Bill. He emphasized that this issue is important for the entire country, not just for any party or individual. Rijiju pointed out that India had One Nation, One Election for two decades after independence, and it was only after Congress misused Article 356 that elections became separated between Parliament and states. He questioned whether Congress believed that Pandit Jawaharlal Nehru’s government was illegal because it followed One Nation, One Election. Rijiju argued that frequent elections are not beneficial and that elections should be held to serve the people and the country.
