What is the common examiner trap about Polity in UPSC exams?

Do not confuse the 42nd Amendment (freeze till 2000) with the 84th Amendment (extended till 2026). Also, note that the 106th Amendment (women reservation) is linked to delimitation after the 2027 census, not the current freeze. Another trap: the 131st Amendment Bill was defeated, not passed.

What should UPSC aspirants remember about Polity for Prelims?

1. Target this Data: 543 Lok Sabha seats frozen as per 1971 census; 42nd Amendment till 2000; 84th Amendment till 2026; 131st Amendment Bill proposed 850 seats. 2. Target this Nodal Body: Delimitation Commission (set up under an Act of Parliament). 3. Target this Legal Point: Article 81(2) – uniform seat-population ratio; 42nd, 84th, 106th Amendments; 131st Amendment Bill.

Delimitation Row: Tamil Nadu Seeks Freeze on 543 Lok Sabha Seats; 131st Amendment Bill to Raise to 850 Defeated

Q: Which constitutional amendment froze the allocation of Lok Sabha seats based on the 1971 census until the year 2000?

42nd Amendment (1976), The 42nd Constitutional Amendment (1976) froze Lok Sabha seats based on the 1971 census until 2000 to encourage population control. The 84th Amendment later extended this freeze until 2026.

Q: Consider the following statements regarding delimitation: 1. The Delimitation Commission is set up under an Act of Parliament. 2. The last delimitation of Lok Sabha constituencies was based on the 2001 census. 3. The 106th Constitutional Amendment provides for one-third reservation of seats for women in the Lok Sabha through delimitation after the 2027 census. Which of the statements given above is/are correct?

Both 1 and 3, Statement 1 is correct as per the article: Delimitation Commission is set up under an Act of Parliament. Statement 2 is incorrect – the last delimitation was based on the 1971 census, not 2001. Statement 3 is correct: the 106th Amendment provides for women reservation through delimitation after the first census post-2026 (i.e., 2027). Hence option C is correct.

Q: According to the article, what was the proposed maximum number of Lok Sabha seats in the 131st Amendment Bill introduced in April 2026?

850, The 131st Amendment Bill proposed to increase the maximum number of Lok Sabha seats from the existing 550 to 850. The bill was defeated in the Lok Sabha. Option A (543) is the current frozen number, B (550) is the current maximum, C (816) is the approximate number after 50% increase on 543 but the bill proposed 850.

Q: What is the primary federal concern raised in the article regarding delimitation based on current population?

Southern states will lose political significance due to lower population growth compared to northern states., The article highlights that states like Kerala, Tamil Nadu, Karnataka, and Andhra Pradesh have controlled population growth better than northern states. A fresh delimitation based on current population would reduce their seat share, violating the federal principle. Options B, C, and D are additional implications but not the primary federal concern.

What This Article Covers

1.Tamil Nadu Legislative Assembly passes resolution to permanently freeze Lok Sabha seats at 543, maintain state-wise distribution, and implement women's reservation from 2029 without linking to delimitation.

2.The Union government's 131st Amendment Bill (April 2026) to raise Lok Sabha seats to 850 was defeated; may be reintroduced with explicit 50% pro-rata increase for all states.

3.Uneven population growth (north vs south) means post-2026 delimitation will reduce southern states' political significance, challenging federal principles.

The Big Picture

Prelims · HighMains · High

Delimitation after the 2026 census threatens to redraw Lok Sabha representation, triggering a federal vs democratic conflict. Tamil Nadu's resolution to freeze seats at 543 and the defeated 131st Amendment Bill (proposing 850 seats) highlight the core tension between population-based representation and protecting states that controlled population growth. This is a high-stakes polity issue for UPSC Mains and Prelims.

Delimitation Process

Delimitation is the process of fixing the number of seats and boundaries of constituencies for Lok Sabha and Legislative Assemblies, performed by a Delimitation Commission set up under an Act of Parliament.

🗳️

Tamil Nadu's Resolution

The TN Assembly urged a permanent freeze on 543 Lok Sabha seats, preservation of current state-wise distribution, and implementation of women's reservation from 2029 without linking to census or delimitation.

📜

131st Amendment Bill

Introduced in April 2026 to increase Lok Sabha seats to 850 with 50% pro-rata increase; defeated in Lok Sabha but may be reintroduced with explicit provisions.

Detailed Analysis & Strategic Depth

Context / Background

Article 81(2) of the Constitution mandates that the ratio of seats to population should be uniform across states. The last delimitation based on the 1971 census fixed 543 Lok Sabha seats. To encourage population control, the 42nd Amendment (1976) froze this allocation until 2000, and the 84th Amendment (2001) extended the freeze until 2026. The 106th Amendment (2023) provides for one-third reservation of women in Lok Sabha and state assemblies, to be implemented through delimitation after the first census post-2026 (i.e., 2027 census).

Core Analysis & Implications

Uneven population growth over five decades (north Indian states like UP, Bihar, MP, Rajasthan grew faster than southern states like Kerala, Tamil Nadu, Karnataka) means a fresh delimitation based on current population would significantly increase seats for northern states while southern states lose political weight. This pits the democratic principle of 'one person-one vote-one value' against the federal principle of equal state representation. The 131st Amendment Bill's proposed 50% pro-rata increase (to 850 seats) would maintain current proportions but does not address the underlying federal imbalance. Additionally, an enlarged Lok Sabha could diminish the Rajya Sabha's role as a check, especially if joint sittings become more frequent to resolve deadlocks.

Future Outlook / Way Forward

The government may reintroduce the 131st Amendment Bill with explicit provisions for a 50% pro-rata increase. However, the author suggests an alternative: freeze Lok Sabha seats at 543 (preserving federal balance), implement women's reservation within existing seats, and increase the number of MLAs in state assemblies to satisfy democratic representation. This approach harmonises federal and democratic principles. The next census (2027) will trigger the delimitation exercise, making this a critical issue for the upcoming parliamentary debates.

Additional Dimension: Cost and Efficiency

Increasing the number of MPs to 850 would raise costs (salaries, MPLADS funds) and reduce parliamentary efficiency. With Lok Sabha sitting only about 60 days a year, more MPs would have less time to raise issues, reducing the house to mere numerical representation rather than meaningful deliberation.
