The Delimitation Bill, 2026

21 May 2026 Source

Exam Summary

The article discusses the proposed Delimitation Bill, 2026, and related constitutional amendment bills (131st Amendment Bill, 2026) which aim to revise the delimitation process in India. Currently, Lok Sabha and State Assembly seats are frozen based on the 1971 census until after 2026 (extended by the 84th Amendment). The proposed bills seek to enable delimitation based on the 2011 census, increase the maximum number of Lok Sabha seats from 550 to 850, and remove the census requirement for the commencement of women's reservation (106th Amendment, 2023). It highlights issues such as the shift in relative seat share among states (benefiting northern states, reducing southern states' representation), changes in the relative power of Lok Sabha vs. Rajya Sabha, and the potential increase in the size of the Council of Ministers. The article also details the proposed composition of the Delimitation Commission and raises concerns about parliamentary control over delimitation timing and census usage.

Prelims Takeaways

  • Delimitation is the process of redrawing boundaries of Lok Sabha and State Assembly constituencies to ensure roughly equal population per constituency.
  • Constitutional provisions (Articles 81, 82, 170) mandate delimitation after each census.
  • The 42nd Amendment (1976) froze seats based on the 1971 census, extended until after 2026 by the 84th Amendment (2001) for population stabilization.
  • The 106th Amendment (2023) introduced 1/3rd women's reservation, contingent on the first census after its commencement and subsequent delimitation.
  • Proposed bills (Delimitation Bill, 2026; 131st Amendment Bill, 2026) aim to use the 2011 census for delimitation, increase Lok Sabha seats to 850, and delink women's reservation from the 2027 census.
  • The proposed Delimitation Commission would comprise a Supreme Court Judge (Chairperson), CEC/EC, and State Election Commissioner.
  • Using the 2011 census would shift Lok Sabha seat allocation, increasing representation for states with higher population growth (e.g., UP, Bihar, Rajasthan) and decreasing for others (e.g., Tamil Nadu, Kerala).
  • Increasing Lok Sabha seats to 850 while Rajya Sabha remains at 250 would alter the Lok Sabha:Rajya Sabha ratio, impacting presidential/vice-presidential elections and joint sittings.
  • The 91st Amendment (2003) limits the Council of Ministers to 15% of Lok Sabha strength; an increased Lok Sabha would allow a larger Council of Ministers.

Elimination Traps

  • Confusing the current constitutional freeze (1971 census) with the proposed basis (2011 census).
  • Misinterpreting the timeline for women's reservation implementation (original vs. proposed changes).
  • Incorrectly recalling the maximum strength of Lok Sabha (current 550 vs. proposed 850).

The Rajya Sabha and the Lok Sabha, the two houses of India's Parliament, have different powers and functions. While the Lok Sabha is the lower house with members directly elected by the people, the Rajya Sabha is the upper house with members indirectly elected by the states. However, when it comes to amending the Constitution, both houses have equal powers. According to Article 368 of the Indian Constitution, any amendment to the Constitution requires the approval of both the Rajya Sabha and the Lok Sabha. Therefore, for a constitutional amendment to be valid, it must be approved by both houses of Parliament, giving them equal powers in the process.

Variation * Parliament has the power to modify or alter existing provisions of the Constitution.

We adopted parliamentary democracy based on the British model, but how does our model differ from that model?
1. As regards legislation, the British Parliament is supreme or sovereign but in India, the power of the Parliament to legislate is limited.
2. In India, matters related to the constitutionality of the Amendment of an Act of the Parliament are referred to the Constitution Bench by the Supreme Court

Select the correct answer using the codes given below.

  1. A. 1 Only
  2. B. 2 Only
  3. C. Both 1 and 2
  4. D. Neither 1 nor 2
Explanation
Correct answer
C. Both 1 and 2

Statement 1 is Correct: The key difference lies in Parliamentary Supremacy. In the British model, Parliament is considered sovereign. This means its legislative powers are supreme, and its laws cannot be challenged by any other body. In India, the Constitution is supreme. Parliament's power to legislate is limited by the Constitution. The judiciary can review laws passed by Parliament and strike them down if they violate the Constitution. Statement 2 is also Correct: This is a specific example of the limitation on Parliament's power in India. The Constitution Bench of the Supreme Court has the authority to review amendments made to existing laws (Acts) and determine if they are constitutional. This power of judicial review ensures the Constitution remains the supreme law.
