131st Constitutional Amendment

This article is written by Gaurav Jain, a student of University of Rajasthan, Law College. This article analyses the constitutional legal framework surrounding the Bill’s defeat, the major judicial pronouncements determining the constitutionality of amending provisions of the Constitution and the overall implications of the Bill’s failure for Indian democracy.

The Fall of the 131st Constitutional Amendment: Democratic Safeguard or Legislative Deadlock?

On April 17, 2026, the Indian Parliament experienced one of the most important moments in its recent history when the Constitution (One Hundred and Thirty-First Amendment) Bill, 2026 was rejected by the Lok Sabha. 

The Union Government, led by Narendra Modi, introduced this Bill to restructure India’s electoral framework in three major ways: expanding the Lok Sabha from 543 to 850 seats, permitting constituency delimitation on the basis of the 2011 Census instead of the 2021 Census, and implementing the 33% reservation for women promised under the Constitution (One Hundred and Sixth Amendment) Act, 2023, popularly known as the Nari Shakti Vandan Adhiniyam.

The defeat of the Bill has revived one of India’s longest-running legislative debates: whether women’s political representation should depend on the politically contentious process of delimitation.

Since the 106th Amendment of 2023 tied the implementation of women’s reservation to the delimitation process after a post-2027 census, the 131st Amendment aimed to break this deadlock by allowing Parliament to use the 2011 Census for delimitation. 

However, by bundling women’s rights reform with a contentious overhaul of the allocation of seats among states, wherein there is a disproportionate fear that northern states will profit at the expense of southern states, rendered the Bill unsuccessful.  

Case Laws

1. Kesavananda Bharati v. State of Kerala

The relevance of this judgment to the 131st Amendment debate is profound.

Critics — including the leader of the opposition, Rahul Gandhi — argued that the Bill, by drastically altering the composition and seat-distribution of the Lok Sabha through what opponents called a partisan use of delimitation, effectively tampered with the federal structure of the Constitution — a core element of its basic structure.

The opposition’s contention that the Bill was an ‘attack on the Constitution’ finds intellectual grounding in the Kesavananda ruling. Had the Bill passed and been challenged before the Supreme Court, the doctrine would have provided a robust constitutional basis for judicial review.

2. Indira Nehru Gandhi v. Raj Narain

This judgment is particularly instructive in the context of the 131st Amendment, which sought to amend Article 82 of the Constitution to allow Parliament — rather than a constitutionally-independent Delimitation Commission — to determine which census data governs delimitation.

Constitutional scholars warned that granting Parliament such executive-legislative control over delimitation could politicise the process and undermine the independence of electoral boundary-drawing, a concern resonant with the principles articulated in Indira Gandhi’s case.

3. Minerva Mills Ltd. v. Union of India

In the context of the 131st Amendment debate, Minerva Mills reinforces the principle that constitutional amendments bundling multiple structural changes without adequate consensus and judicial safeguards risk validity challenges.

The proposed expansion of Lok Sabha from 543 to 850 seats, combined with a proportional reallocation of seats, would have altered the ratio of Lok Sabha to Rajya Sabha from 2.2:1 to 3.3:1 — fundamentally affecting the power balance in joint sittings of Parliament, a concern that touches the federal structure that Minerva Mills protects.

4. S.R. Bommai v. Union of India

The defeat of the 131st Amendment Bill was, to a significant extent, a reflection of federal anxieties in action. States in southern India—including Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, and Telangana- strongly opposed the Bill because they feared that reallocating seats on the basis of updated population figures would reduce their parliamentary representation and effectively penalise them for successfully controlling population growth over several decades.

This ‘North-South divide’ raised concerns directly engaging the S.R. Bommai principles: a constitutional amendment that disproportionately undermines the representation of specific states strikes at the core of India’s federal compact.

To Sum Up

The defeat of the Constitution (131st Amendment) Bill in 2026 has been a key turning point in the history of the Constitution of India by both illustrating the strength of the amendment process in Article 368 and reminding us (as if needed) of the deep political and federal divisions that continue to hinder India’s legislative process.

The failure of this Bill did not merely reflect a disagreement over numbers; it also exposed deep divisions over the structure of Indian democracy, particularly regarding how the system represents people, on what basis it grants representation, and at what cost.

Indian constitutional jurisprudence provides a well-developed intellectual framework for evaluating both the goals of the Bill and the basis for its failure, as well as evaluating the validity of those goals.

The two-thirds majority requirement of Article 368 is not just a mechanical requirement; it is an intentional buffer to ensure that any changes made to the structure of the Constitution will have the near-consensus of the entire political community in order to resist the power of the majority.

The required course of action is clear; however, political considerations will make implementation difficult. The government can implement women’s reservation immediately, without linking it to delimitation, under the current 543-member Lok Sabha system.

The support from across party lines was evident in the 106th Amendment, which passed by nearly unanimous vote in 2023. An independent commission must conduct delimitation on the basis of a new census and ensure a transparent process that protects states that have successfully achieved population stabilisation.

Therefore, this large constitutional change requires building consensus over time, rather than one political party acting alone, as was evident in the defeat of the 131st Amendment Bill throughout the history of the Indian Parliament.

Frequently Asked Questions

What was the Constitution (131st Amendment) Bill, 2026?
The Constitution (131st Amendment) Bill, 2026, was introduced in the Lok Sabha on April 16, 2026. It sought to expand the Lok Sabha from 543 to 850 seats, allow delimitation based on the 2011 Census (instead of waiting for a post-2027 census), and operationalise the 33% women’s reservation promised under the 106th Constitutional Amendment Act, 2023.

    Why did the 131st Amendment Bill fail?
    The Bill failed because it did not secure the constitutionally mandated special majority under Article 368. With 528 members present and voting, at least 352 votes were required. The government received only 298 votes. The opposition, united under the INDIA bloc, objected primarily to the Bill’s linkage of women’s reservation with delimitation and its perceived threat to southern states’ parliamentary representation.


    What is the Basic Structure Doctrine, and how is it relevant here?
    The Basic Structure Doctrine, established in Kesavananda Bharati v. State of Kerala (1973), holds that Parliament cannot amend those features of the Constitution that constitute its basic identity — including democracy, federalism, judicial review, and the rule of law. Critics argued that the 131st Amendment’s provisions could potentially undermine India’s federal structure by disproportionately affecting the representation of southern states, potentially engaging this doctrine.


    What happens to women’s reservation after the Bill’s defeat?
    The 33% women’s reservation under the 106th Constitutional Amendment (2023) remains in force but is deferred until after delimitation conducted post-census. Without the 131st Amendment, implementation is unlikely before 2034. The opposition has demanded that the government now implement women’s reservation on the existing 543-seat Lok Sabha for the 2029 elections by removing the delimitation conditionality through a fresh, simpler amendment.


    Why did Southern states oppose the Bill?
    Southern states — including Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, and Telangana- feared that seat-allocation proportional to updated population figures would reduce their parliamentary representation, effectively penalising them for successfully controlling the population growth over the past five decades, while rewarding states with higher population growth.
