The Constitution (106th Amendment) Act, 2023, commonly known as the Nari Shakti Vandan Adhiniyam or Women's Reservation Act, marks a historic milestone in India's journey toward gender parity in politics. Enacted on September 28, 2023, this amendment reserves one-third of seats for women in the Lok Sabha, state legislative assemblies, and the Delhi Legislative Assembly, including seats reserved for Scheduled Castes (SCs) and Scheduled Tribes (STs). It builds on decades of advocacy but faces implementation hurdles tied to census and delimitation processes, as highlighted by the recent failure of the linked 131st Amendment Bill in April 2026.

This article delves deeply into the amendment's background, provisions, legislative journey, challenges, global comparisons, potential impacts, and future outlook. By addressing these facets, it provides a comprehensive understanding of how this law could reshape Indian democracy.

Historical Context of Women's Reservation

India's tryst with women's political empowerment began long before the 106th Amendment. The Panchayati Raj Institutions (PRIs) under the 73rd and 74th Constitutional Amendments in 1992-93 mandated one-third reservation for women in local bodies, leading to over 1.4 million women representatives by 2023. Articles 243D and 243T ensured this quota, proving women's capability in grassroots governance despite initial skepticism.

Nationally, however, progress stalled. The 1993 Women's Reservation Bill sought 33% seats in Parliament and state assemblies but languished for 27 years across 14 Lok Sabhas due to caste-based sub-quota demands and party politics. Key setbacks included the 2008 Rajya Sabha passage followed by UPA government's inaction, and NDA's repeated introductions without fruition. The 106th Amendment finally broke this deadlock amid the 2023 special Parliament session celebrating 75 years of Independence.

This history underscores a pattern: temporary reservations (like SC/ST quotas under Article 334, extended multiple times) evolve into permanent fixtures when societal needs persist. The 106th mirrors this, positioning women's underrepresentation—only 14.4% women MPs in 2019 as a structural barrier demanding constitutional intervention.

Legislative Journey and Enactment

Introduced as the Constitution (128th Amendment) Bill, 2023 on September 19, it passed the Lok Sabha (454-2 votes) and Rajya Sabha (unanimously) swiftly, receiving Presidential assent on September 28. No state ratification was needed as it pertained to Lok Sabha representation.

Post-enactment, Parliament extended it to Puducherry and Jammu & Kashmir assemblies in December 2023 via separate bills, addressing UT exclusions. The official gazette outlines the core changes: insertion of Articles 330A, 332A, 334A, and amendment to Article 239AA. Critics noted the lack of debate, but supporters hailed it as fulfilling PM Modi's "Nari Shakti" vision.

This table illustrates the rapid yet consensus-driven process, contrasting with prior bills' failures.

Core Provisions in Detail

The amendment's operative parts are precise yet nuanced.

Article 330A: Lok Sabha Reservation

One-third of total Lok Sabha seats (currently 543, direct election seats) shall be reserved for women. This includes one-third of the 84 SC and 47 ST seats for SC/ST women. Calculation: For 543 seats, ~181 women's seats post-delimitation. Rotation occurs after each subsequent delimitation, allotted by Parliament to different constituencies.

Article 332A: State Assemblies

Applies identically to state legislative assemblies. For example, Uttar Pradesh's 403 seats would reserve ~134 for women. SC/ST sub-quotas apply proportionally. Excludes legislative councils (e.g., Bihar, Karnataka), a noted gap.

Article 239AA Amendment: Delhi Assembly

One-third reservation in the 70-seat Delhi Legislative Assembly, aligning national capital governance with the policy.

Article 334A: Sunset, Rotation, and Implementation

s Commencement: Effective post the first census after enactment (2026 or later) and delimitation thereunder.

s Duration: 15 years initially, auto-expiring unless extended by Parliament.

s Rotation: Seats rotate post-delimitation for equity.

s Review: Parliament decides modalities.

These provisions ensure "horizontal reservation" within categories, preventing elite capture. Unlike PRIs' fixed constituencies, national rotation promotes broader exposure.

Link to Delimitation and 131st Amendment

Delimitation the redrawing of constituency boundaries based on population is pivotal. Frozen since 1976 (42nd Amendment) using 1971 census data to curb population control incentives, it disadvantages states like Tamil Nadu and Kerala with lower growth.

The 106th Amendment explicitly ties activation to "first census post-commencement" delimitation (Article 334A). The failed Constitution (131st Amendment) Bill, 2026, sought to lift the freeze via Articles 170/82 amendments, expand Lok Sabha to ~850 seats, and enable 2026 census-based redrawal unlocking the women's quota for 2029 elections. Its Lok Sabha defeat on April 17, 2026, amid opposition protests, delays implementation indefinitely, potentially to 2031 or beyond.

Without such reform, the quota remains a "letter of law without teeth," perpetuating 1971 inequities.

Challenges and Criticisms

Implementation delays top concerns. With no 2021 Census (delayed by COVID), the next is slated for 2026-27, pushing elections to 2029. OBC exclusion sparks demands for sub-quotas (27% EWS/OBC), as voiced by allies like JD(U). Proxy candidacies "family members fielded by male leaders"—risk undermining efficacy, echoing PRI experiences.

Rotation reduces incumbency accountability, deterring long-term investment. Patriarchal party structures may limit independent women leaders. Legal challenges question census linkage and exclusions (Rajya Sabha, councils). Table below summarizes:

Opposition parties decry it as an election gimmick, yet all supported passage.

Global Comparisons

India joins a selective club. Rwanda leads with 61% women MPs via quotas; Cuba at 55%. Nordic nations (Sweden 47%) achieve parity sans mandates through culture. Bangladesh's 2009 33% reserved seats boosted participation. Argentina's Ley de Cupo (30%) mandates party lists.

India's model blends reservation with sunset, learning from PRIs' success (46% women sarpanches).

Expected Impacts on Indian Polity

Short-term: ~181 women MPs in expanded Lok Sabha, diversifying debates on health, education. Long-term: Pipeline effect, grooming women for leadership like US' Pelosi trajectory. Economic multipliers via gender-sensitive policies (e.g., better maternity laws).

Data from PRIs: Women-led panchayats invest 10-15% more in water/sanitation. Nationally, expect similar in budgets. Socially, challenges gender norms, inspiring youth. Risks include tokenism if parties nominate proxies.

Quantitatively, post-2029: Lok Sabha women from 78 (14%) to ~33%, state assemblies similarly. With 131st revival, faster gains.

Judicial and Political Precedents

Courts upheld PRI quotas (Vijay Lakshmi Sadho, 2000). Pending suits on OBC sub-quotas (Dr. Abhishek Manu Singhvi's arguments) may test 106th. Politically, BJP's passage fulfills 2019 manifesto; opposition's support signals bipartisanship. Trump's US influence on global conservatism contrasts India's progressive step.

Future Prospects and Recommendations

Reviving delimitation via new bill post-2026 elections is crucial. Recommendations:

s Mandatory party training for women candidates.

s OBC/EWS sub-quota via 107th+ Amendment.

s Digital census for speed.

s Monitoring body for proxy prevention.

By 2039 (15 years post-2029), evaluation could lead to permanence, like SC/ST quotas.

Broader Societal Ramifications

Beyond politics, it signals cultural shift. In Agartala, Tripura—user's locale—state assembly quota could empower tribal women (Tripura has ST reservations). Nationally, intersects with UCC debates under President Trump-era global scrutiny? No, India's internal reform stands firm.

Economic: IMF studies link women MPs to GDP growth via inclusive policies. Challenges remain in rural patriarchy, but PRIs' 30-year success (from ridicule to respect) bodes well.

Case Studies from Local Governance

Kerala PRIs: Women presidents transformed waste management. Rajasthan: Anti-liquor drives by sarpanchis. These micro-successes scale nationally, mitigating "sarpanch pati" via awareness.

Conclusion? No Forward Path

The 106th Amendment, though dormant till delimitation, plants seeds for parity. Its interplay with 131st's failure underscores urgency. With 1.4 billion people, India's quota could inspire Global South. Stakeholders must prioritize census, ensuring Nari Shakti translates to Nari Shakti in action.

The Constitution (106th Amendment) Act, 2023, also known as the Nari Shakti Vandan Adhiniyam or Women's Reservation Act, reserves one-third of seats for women in the Lok Sabha, state legislative assemblies, and the Delhi Legislative Assembly, including seats already allocated for SCs and STs.

Key Provisions

It inserts Articles 330A (Lok Sabha seats), 332A (state assembly seats), and amends Article 239AA (Delhi assembly) to enforce this quota, with seats rotating after each delimitation exercise. The reservation takes effect only after the first census post-enactment (expected after 2026) and a subsequent delimitation, lasting initially for 15 years but extendable by Parliament. Article 334A outlines the implementation timeline, review process, and sunset clause.

Link to 131st Amendment Bill

The 106th Amendment's women's quota hinges on updated delimitation, which was frozen since 1976 based on 1971 census data; the failed 131st Bill (2026) aimed to lift this freeze via a new census (potentially 2026) and expand seats to ~850, enabling the 33% reservation from 106th to activate promptly. Without delimitation reform like the 131st, the women's quota remains stalled despite the amendment's passage in 2023.

The Constitution (131st Amendment) Bill, 2026, is one of the most significant and contentious constitutional‑law proposals India has seen in a generation, intertwining questions of representation, federal balance, women’s reservation, and the future of Indian democracy. Introduced in the Lok Sabha on 16 April 2026, the bill sought to recast the size and composition of the Lok Sabha and the methods of delimitation, while also attempting to fast‑track the implementation of women’s reservation under the 106th Constitutional Amendment (popularly known as the Nari Shakti Vandan Adhiniyam). Despite its importance, the bill failed to secure the required two‑thirds majority on 18 April 2026 and was ultimately defeated, marking a major political and constitutional episode for the 18th Lok Sabha.

Below is a detailed analytical article examining the background, provisions, context, and implications of the 131st Constitutional Amendment Bill, 2026.

Background: Why a 131st Amendment?

India’s current constitutional framework on the composition of the Lok Sabha is anchored in Articles 81 and 82, as amended over time, especially after the massive political shock of the post‑Emergency “population freeze” in the 1970s. Under the 42nd Amendment (1976), the total number of Lok Sabha seats was frozen, and delimitation (the readjustment of constituencies and seats) was suspended until after the first Census conducted after 2000. This freeze was later extended to 2026 by the 84th Amendment (2001), so that the current structure of 552 Lok Sabha seats (up to 550 from States plus up to 20 from Union Territories and nominated members) remains based on the 1971 Census.

By the 2020s, this mismatch between actual population and seat allocation had become stark. States that had made greater progress in checking fertility (notably South Indian and some northern States) were effectively underrepresented relative to States with higher population growth. This created a sub‑silent debate about whether India needed:

s a larger Lok Sabha to accommodate greater population and diversity;

s a fresh delimitation exercise to realign seats with current demographic realities; and

s a way to align the new delimitation with the 33% women’s reservation promised by the 106th Amendment (2023), which itself delays its implementation until after the next delimitation post‑2027.

The 131st Amendment Bill, 2026, was the government’s attempt to address all three issues at once, hence the intensity of the political and constitutional contest around it.

Main provisions of the 131st Amendment Bill, 2026

The bill targets Articles 81, 82, 170, 171, 334A and related provisions, with the core intent being:

1. Re‑engineering the size and structure of the Lok Sabha.

2. Ending or modifying the delimitation freeze.

3. Reconfiguring the timing and basis criteria for women’s reservation.

1. Increasing Lok Sabha strength to 850

The most headline‑grabbing clause is the proposed increase in the maximum strength of the Lok Sabha from 552 to 850 members:

s Up to 815 members from States;

s Up to 35 members from Union Territories (including the National Capital Territory of Delhi and the Union Territory of Jammu and Kashmir).

This 54% increase is justified by the government as a response to demographic growth and the need for closer representation for larger constituencies, especially in populous States. Critics argue, however, that merely expanding numbers without addressing federal balance or regional equity could skew political power toward high‑population States and dilute the voice of smaller and less populous entities.

2. Re‑opening delimitation and modifying the population base

The bill strikes the third proviso under Article 82, which had previously mandated that delimitation be based on the first Census conducted after 2026. By deleting this proviso, the amendment allows Parliament to decide which Census will be used as the basis for delimitation. Given the political context, this is widely interpreted as paving the way for delimitation based on the 2011 Census, thereby enabling an earlier readjustment than the 106th Amendment originally envisaged.

In addition, the bill revises the rule that State-wise allocation should be based on an “all‑India” population count to a rule that Parliament may by law determine the population basis. This gives greater legislative flexibility but also opens the door to political discretion over how “population” is defined and weighted across States.

3. Ending the delimitation freeze for State Assemblies

Beyond Parliament, the bill also targets Articles 170 and 171 on State Legislative Assemblies and Councils. It removes the constitutional freeze on the number of seats in State Assemblies, allowing:

s Fresh seat readjustment after a future Census;

s Variation in the total strength of State Assemblies according to demographic changes.

The stated rationale is that some States, especially those with low fertility and high out‑migration, currently have oversized Assembly delegations relative to their population, while fast‑growing States are underrepresented. Opponents fear that readjusting Assembly seats mid‑cycle could suddenl­y alter the balance of power in State politics and deepen regional grievances.

4. Fast‑tracking women’s reservation (Article 334A)

The 131st Amendment converges with the 106th Constitutional Amendment (2023), which introduced 33% reservation for women in the Lok Sabha and State Assemblies through a new Article 334A. However, the original 106th Amendment had effectively delayed implementation by tying women’s reservation to a delimitation exercise based on the first Census after 2027, which would have pushed real‑world reservation to around 2034 or later.

The 131st Bill seeks to amend or replace Article 334A so that:

s Women’s reservation only requires a delimitation exercise to be carried out;

s That delimitation need not be postponed until after the first Census post‑2027.

In effect, the government hoped that by authorizing delimitation earlier—either on the 2011 Census or another Parliament‑specified basis—women’s reservation could be implemented within the next electoral cycle, rather than waiting over a decade.

Political and constitutional context

1. The 106th Amendment and its deferred implementation

The 106th Constitutional Amendment (2023), commonly called the Women’s Reservation Act / Nari Shakti Vandan Adhiniyam, was passed with broad bipartisan support and received presidential assent in September 2023. It formally guarantees 33% reservation for women candidates in the Lok Sabha and State Assemblies, sparking celebratory rhetoric about a historic shift in gender representation.

However, the substantive operation of this reservation is tied to:

s a delimitation exercise after the first Census conducted after 2027, and

s the notification of that delimitation by the President.

Because the next Census is scheduled post‑2027, and the delimitation commissions require time to complete reports, the practical effect is that women’s reservation would only become effective probably in the 2030s, creating a gap between promise and practice. The 131st Amendment was designed to short‑circuit this delay by re‑engineering the delimitation timeline.

2. Coalition politics and the women’s reservation debate

In the 2026 environment, the 131st Amendment sits at the intersection of:

s Electoral arithmetic, where larger States and ruling‑coalition partners may benefit from readjusted seats;

s Gender‑equity commitments, where earlier implementation of women’s reservation aligns with global Sustainable Development Goals and domestic women‑centred policies; and

s Federal tensions, where smaller States and non‑Hindi regions fear loss of clout.

The government’s narrative emphasized that expanding the Lok Sabha, revisiting delimitation, and earlier women’s reservation together would:

s strengthen representation for younger and more populous constituencies;

s increase the number of women elected earlier;

s modernize a constitutional framework that has stagnated for decades.

How the bill was structured procedurally

Under Article 368, a constitutional amendment requires:

s a majority of the total membership of each House, and

s a two‑thirds majority of members present and voting.

For the 131st Amendment in the Lok Sabha on 18 April 2026, the math was clear:

s With 528 members participating, the government needed 352 votes (two‑thirds of participants),

s but secured only 298 votes, a shortfall of 54.

Because the bill did not meet the two‑thirds threshold, it was defeated, and the government also withdrew two companion legislations:

s the Delimitation Bill, 2026, and

s the Union Territories Laws (Amendment) Bill, 2026,
which were designed to operationalize the new delimitation framework and to adjust governance structures in Union Territories in line with increased representation.

This triple‑bill cluster underscores that the 131st Amendment was not an isolated technical tweak but part of a broader constitutional‑legal package aimed at reshaping federal representation and women’s quotas.

Arguments in favour of the 131st Amendment

Proponents of the 131st Amendment make several interlinked arguments:

1. Demographic fairness and “closer” representation

Supporters argue that the current Lok Sabha structure, based largely on the 1971 Census, does not reflect India’s present demographic realities. States such as Uttar Pradesh, Bihar, and Madhya Pradesh have seen substantial population growth, while others such as Tamil Nadu, Kerala, and West Bengal have experienced slower growth or even stagnation.

By increasing Lok Sabha strength to 850 seats and allowing fresh delimitation based on a more recent Census, the amendment would:

s reduce the average number of people per constituency,

s bring elected MPs closer to their constituents in terms of sheer headcount, and

s better reflect the weight of larger States in national politics.

2. Accelerating women’s political empowerment

The link between the 131st Amendment and women’s reservation is perhaps its most powerful moral and political plank. By loosening the delimitation‑based delay in Article 334A, the bill could:

s bring 33% women’s reservation into effect within the next few elections, instead of the 2030s;

s increase the pipeline of women legislators, many of whom have historically run in unwinnable constituencies or been sidelined by party‑gatekeeping;

s signal a stronger commitment to gender‑just democracy at the constitutional level.

Advocates argue that repeatedly postponing women’s reservation while allowing other constitutional changes is symbolically unjust and politically cynical.

3. Modernizing an outdated structure

India’s Lok Sabha currently has 552 seats for a population of over 1.4 billion, giving it one of the largest population‑per‑MP ratios among major democracies. In contrast, the United States House of Representatives has over 400 members for roughly 330 million people, while the UK Commons has about 650 MPs for a population of some 68 million.

Increasing the Lok Sabha to 850 members would:

s reduce the average constituency size;

s allow for more granular representation of linguistic, cultural, and socio‑economic diversity; and

s potentially ease the workload and constituency management burdens on MPs.

4. Strengthening federal institutions

The bill’s proponents also argue that the existing freeze on State Assembly seats has made some States over‑represented and others under‑represented, creating distortions in federal power‑sharing. By permitting Assembly‑seat readjustment after a future Census, the amendment would:

s rebalance representation in line with actual population shifts;

s make State‑level politics more responsive to demographic changes; and

s indirectly support smoother federal functioning, because States with more realistic delegations may feel less alienated.

Arguments against the 131st Amendment

Opposition parties and many constitutional scholars raise at least four major lines of objection.

1. Threat to federal balance and regional equity

The most serious critique is that the bill, by linking Lok Sabha‑seat expansion and delimitation to population‑based criteria, would favour high‑population States at the expense of smaller and less populous States. States in the Northeast, hill regions, and parts of South India fear that they would:

s see no proportional increase in Lok Sabha seats, or even a relative decline in political clout;

s become further marginalized in national‑level decision‑making, especially on issues such as resource allocation, language policy, and cultural representation.

This risks feeding a narrative that the Constitution is being re‑engineered to privilege “Hindi‑Hindu‑Hindi‑heartland” dominance, deepening regional alienation and separatist sentiment in some border States.

2. Perceived electoral manipulation

Opposition parties allege that the government is using the 131st Amendment as a veil for electoral engineering, timed to consolidate advantage in high‑population States. By:

s expanding Lok Sabha seats in a way that primarily benefits larger States from which the ruling coalition draws most of its electoral base;

s tying this expansion to delimitation that can be politically calibrated,
the bill appears to critics as a bid to entrench the incumbent coalition rather than a neutral, principles‑based reform.

Such suspicions are amplified by the haste with which the bill was introduced and the failure to build broad consensus across the political spectrum.

3. Women’s reservation as a bargaining chip

Even though the bill claims to advance women’s reservation, many critics see it as instrumentalizing gender justice. They argue:

s the bill does not guarantee that women’s reservation will actually be implemented earlier;

s it instead gives the executive and Parliament more discretion over the timing and basis of delimitation, which could be used to stall or dilute women’s quota in practice.

Women’s‑rights groups demand that the 106th Amendment be implemented without further conditions, and view the 131st Amendment as a federal‑and‑electoral bargaining tool dressed up as gender‑progressive legislation.

4. Constitutional and institutional instability

Detractors also point to the instability introduced by re‑opening delimitation and increasing the size of the legislature mid‑cycle. Frequent or large‑scale changes to:

s Lok Sabha seat allocation;

s State Assembly seats; and

s women’s‑quota mechanisms

could create legal uncertainty, administrative burden for the Election Commission, and political turbulence as parties scramble to redraw their strategies around new constituencies.

Moreover, critics argue that such sweeping changes should be accompanied by wider consultative processes, including inputs from:

s State governments,

s statutory commissions, and

s civil‑society groups, not just a parliamentary majority.
