India’s Lok Sabha currently has 543 elected members, but the number of seats allocated to states has remained frozen for decades despite major population changes.
This has led to differences in the number of voters represented by each MP across constituencies.
In April 2026, the government introduced the Delimitation Bill, 2026 along with constitutional amendment proposals to restart the process of redrawing parliamentary and assembly constituencies.
The government said the proposals would help update representation based on demographic changes. Opposition parties and several state governments argued they could alter the political balance between states.
So what did the bill propose, how many seats could change, and why did it become controversial?
What Is Delimitation?
Delimitation means redrawing the boundaries of electoral constituencies.
Its purpose is to ensure that constituencies have a similar population size and that representation reflects demographic changes.
Articles 81 and 82 of the Constitution provide for the allocation of Lok Sabha seats among states and allow constituencies to be redrawn after every Census through a delimitation exercise.
However, this process was frozen through constitutional amendments.
The 42nd Constitutional Amendment Act, 1976 froze the allocation of Lok Sabha seats among states based on the 1971 Census.
The 84th Constitutional Amendment Act, 2001 extended this freeze until the first Census after 2026. The aim was to ensure that states which controlled population growth were not politically disadvantaged.
What Did The Delimitation Bill 2026 Propose?
The Delimitation Bill, 2026 aimed to create a framework for a fresh delimitation exercise.
It proposed:
Redrawing Lok Sabha constituencies
Redrawing state assembly constituencies
Readjusting allocation of seats
Repealing the Delimitation Act, 2002
The bill proposed creating a Delimitation Commission.
The Commission would include:
A Chairperson who is or has been a Supreme Court judge
The Chief Election Commissioner or an Election Commissioner nominated by the CEC
The State Election Commissioner of the concerned state
Under the proposed law, the Central government would appoint the Chairperson and determine the Commission's term.
Each state would also have 10 associate members to assist the Commission.
How Many Lok Sabha Seats Could Increase?
The current Lok Sabha has 543 elected members.
The Constitution currently allows a maximum strength of 550 members:
Up to 530 members from states
Up to 20 members from Union Territories
The linked Constitution (131st Amendment) Bill, 2026 proposed increasing the Constitution's ceiling on Lok Sabha membership from 550 to 850 members.
Up to 815 members from states
Up to 35 members from Union Territories
However, 850 was only the maximum limit. The final number of seats would depend on the actual delimitation exercise.
Numbers like 815 or 816 seats were discussed as possible outcomes, but they were not fixed in the bill.
Which States Could Gain Or Lose Representation?
The biggest debate around delimitation was about how seat redistribution could affect states.
According to PRS India’s analysis, if Lok Sabha’s current strength of 543 seats remained unchanged and seats were redistributed based on population:
Uttar Pradesh could increase from 80 to 89 seats
Bihar could increase from 40 to 46 seats
Rajasthan could increase from 25 to 30 seats
Meanwhile:
Tamil Nadu could decrease from 39 to 32 seats
Kerala could decrease from 20 to 15 seats
Southern states argued that population-based redistribution could reduce their relative influence because they had lower population growth compared with several northern states.
Why Was Women’s Reservation Linked To Delimitation?
The debate also involved the 106th Constitutional Amendment Act, 2023, also known as the women’s reservation law.
The law provides for one-third reservation for women in the Lok Sabha and state assemblies.
However, its implementation was linked to a future delimitation exercise based on the first Census conducted after the Act came into effect.
The proposed constitutional amendment removed this condition, allowing Parliament to decide the Census and timing framework for delimitation.
The government said the amendment was intended to enable implementation before the 2029 Lok Sabha elections.
Opposition parties argued that women’s reservation should not be tied to delimitation.
Why Did The Bill Not Pass In April 2026?
The Delimitation Bill was introduced in Lok Sabha on 16 April 2026.
The Constitution (131st Amendment) Bill, 2026 failed to secure the special majority required under Article 368. Since the Delimitation Bill depended on the constitutional amendment, the government subsequently withdrew it.
A Constitution Amendment Bill requires:
Majority of the total membership of the House
Two-thirds majority of members present and voting
After the constitutional amendment failed, the government withdrew the related Delimitation Bill and Union Territories Laws Amendment Bill.
What Would Delimitation Mean For Voters?
If implemented, delimitation could directly change voter representation.
Your Lok Sabha or assembly constituency boundaries could be redrawn.
Some states could receive a larger or smaller share of Lok Sabha seats., while others could see changes in their share of seats.
The number and location of reserved constituencies for Scheduled Castes and Scheduled Tribes could also change.
In simple terms, delimitation could decide who represents you and how political power is distributed across states.
The Bigger Debate: Representation Vs Federal Balance
The delimitation debate is about two competing ideas.
One argument says representation should match population because every voter deserves equal weight.
The other says states that controlled population growth should not lose political influence because of demographic changes.
The final decision on delimitation could shape India’s electoral system and federal balance for decades.
