The Constitution (131st Amendment) Bill, 2026, was introduced in Lok Sabha on April 16, 2026, to overhaul India’s electoral map. It proposes increasing the maximum strength of the Lok Sabha from 550 to 850 members to reflect population changes. Crucially, it seeks to lift the long-standing freeze on seat allocation based on the 1971 Census, shifting the base to the 2011 Census for immediate delimitation. The Bill also decouples women’s reservation from the requirement of a new post-2023 census, potentially fast-tracking its implementation for the 2029 General Elections.
The Union Government introduced a legislative package comprising the Constitution (131st Amendment) Bill, the Delimitation Bill, and the UT Laws (Amendment) Bill. These collectively aim to end the 50-year freeze on parliamentary seat reallocation and expand the Lower House.
The Bills were tabled in the Lok Sabha in New Delhi on April 16, 2026. This move comes ahead of the scheduled 2027 Census to ensure the 2029 elections reflect modern demographic realities.
The Ministry of Law and Justice is the nodal ministry. The process involves the Election Commission of India and a proposed Delimitation Commission chaired by a retired Supreme Court Judge.
The Amendment removes the constitutional block that mandated waiting for a post-2026 census. It allows the government to use the 2011 Census data for redrawing boundaries. Once passed, a Delimitation Commission will be formed to assign the 850 seats across states based on population density, ensuring "one citizen, one vote" parity.
This is vital for democratic representation as the current seat distribution is based on 1971 data. It directly impacts Article 81 (Composition of Lok Sabha) and Article 82 (Readjustment after each census). It also settles the legal hurdle for the 106th Amendment (Women’s Reservation Act).
In 1976, the 42nd Amendment froze seats based on the 1971 Census to encourage population control. In 2001, the 84th Amendment extended this freeze for another 25 years (until 2026) to prevent states with successful population planning from losing political power.
The last Delimitation Commission was set up in 2002 (Kuldeep Singh Commission), which redrew boundaries but did not increase the total number of seats. The Nari Shakti Vandan Adhiniyam (2023) originally linked women's seats to a post-amendment census.
The Bill relates to Article 81, Article 82, and Article 170. It also touches upon the "Proportional Representation" principle and the powers of a Delimitation Commission, whose orders have the force of law and cannot be challenged in any court.
The increase in MPs will lead to a larger Council of Ministers (up to 122 members per Article 75). It may also shift political gravity toward northern states, potentially causing friction with southern states that have lower population growth rates.

2. When the orders are laid before the Lok Sabha, they can be modified by the Parliament.
Which of the statements given above is/are correct?
Answer: 1 only. (Statement 2 is wrong because Parliament has no power to modify the orders).
PYQ 2:
Assertion (A): The number of seats in the Lok Sabha has remained unchanged since the 1970s despite a massive population increase.
Reason (R): The 84th Constitutional Amendment Act, 2001, extended the freeze on seat allocation until 2026 to support population stabilization policies.
Answer: Both A and R are true, and R is the correct explanation of A. (The freeze was a policy tool to ensure states with lower birth rates were not penalized).
Question: "The proposed expansion of the Lok Sabha through the 131st Amendment Bill addresses the crisis of representation but raises concerns regarding federal parity. Discuss."
Examiners frequently focus on the Constitutional Amendments (42nd, 84th, 106th, and now 131st). For Prelims, memorize the specific years and Census dates. For Mains, focus on the Federalism vs. Representation debate, as this is a high-probability topic for GS Paper II.
