For nearly three decades, one idea kept returning to the floor of the Indian Parliament, only to slip away each time before it could become law. It arrived first in 1996, carried into the Lok Sabha by a coalition that would not survive the year. It came back in 1998, in 1999, in 2008, and in 2010 — passed once by the Rajya Sabha, then left to lapse in the lower house. Committees studied it, members walked out over it, and governments of every stripe promised it. Then, in September 2023, in the first bill taken up inside India’s new Parliament building, both houses finally passed the Constitution (106th Amendment) Act — the Nari Shakti Vandan Adhiniyam — reserving one-third of seats in the Lok Sabha and the state assemblies for women. This timeline follows that journey from a 1917 delegation seeking the vote to the delimitation debates of 2026, keeping a careful line between what the Constitution now says and what still has to happen before a single reserved seat exists.
The Women’s Reservation Bill is the popular name for legislation reserving one-third of directly elected seats for women in the Lok Sabha, the state legislative assemblies and the Legislative Assembly of the National Capital Territory of Delhi. After failing to pass on several occasions between 1996 and 2010, it was enacted as the Constitution (106th Amendment) Act, 2023, and christened the Nari Shakti Vandan Adhiniyam.
The amendment inserted Articles 330A, 332A and 334A. It reserves one-third of seats for women, including one-third of the seats already set aside for Scheduled Castes and Scheduled Tribes. Crucially, Article 334A makes the reservation take effect only after a delimitation exercise conducted on the basis of the first census taken after the Act comes into force. The Act was notified into force on 16 April 2026, but the reserved seats themselves await that census-and-delimitation sequence, so no seat is reserved as of mid-2026.
A dated record of the most recent, and most contested, chapter. Reported as parliamentary fact, kept separate from the settled history below.
The most significant recent movement came in April 2026. On 16 April 2026, the Union Ministry of Law and Justice issued a gazette notification bringing the Constitution (106th Amendment) Act, 2023 formally into force. That step is often misread as switching the reservation on. It did not. The Act’s own text, in Article 334A, says the reservation applies only after a delimitation exercise based on the first census taken after commencement. Bringing the Act into force started that clock; it did not fill a single reserved seat.
On the same day, the government introduced three linked bills in the Lok Sabha to try to move faster. The centrepiece was the Constitution (131st Amendment) Bill, 2026, which sought to amend Article 82 so that Parliament could choose which census to use for delimitation — in practice, allowing the existing 2011 Census figures to be used rather than waiting for a fresh count. The same bill proposed raising the maximum size of the Lok Sabha to 850 seats. It was accompanied by the Delimitation Bill, 2026 and the Union Territories Laws (Amendment) Bill, 2026.
A constitutional amendment needs a special majority: at least two-thirds of the members present and voting, and a majority of the total membership of the house. On 17 April 2026, the 131st Amendment Bill fell short. According to the parliamentary record, it received 298 votes in favour and 230 against — below the roughly 352-vote threshold a special majority required that day. With the enabling amendment defeated, the government withdrew the two companion bills, which had been tied to it.
The practical consequence is straightforward and important: as of July 2026, the reservation remains enacted but inoperative, and the constitutional route to switching it on — a census followed by delimitation — is unchanged. Whether and when that census and delimitation happen is a matter of government decision and future legislation, and this page does not assume a timeline that has not been officially announced.
The provisions, the vocabulary and the mechanics, explained plainly.
Start with the core promise. The 106th Amendment reserves one-third of the seats filled by direct election in the Lok Sabha and the state legislative assemblies for women. That is often described as 33 percent, and the two phrasings mean the same thing. The reservation also extends to the assembly of the National Capital Territory of Delhi. It does not touch the Rajya Sabha or the state legislative councils, because those bodies are not filled by direct election in the same way.
The amendment did this by inserting three new articles. Article 330A provides the reservation of one-third of Lok Sabha seats for women. Article 332A does the same for the state assemblies and Delhi. A third provision, Article 334A, sets the timing and the rules for how long the reservation lasts and how reserved seats move around.
India already reserves a share of seats for Scheduled Castes and Scheduled Tribes in proportion to their population. The 106th Amendment layers the women’s quota on top of that structure. One-third of the seats reserved for SC communities, and one-third of those reserved for ST communities, will now go to women from those groups. In other words, the women’s reservation is a slice cut across the whole of the directly elected house, including the seats already earmarked for SC and ST representation, rather than a separate block bolted on beside them.
A reserved seat is not fixed to one place forever. Under the amendment, the specific constituencies reserved for women are to be determined by law and are expected to rotate after each future delimitation exercise. Rotation is meant to spread the reservation across different constituencies over time, so that no single seat is permanently reserved and, in principle, most areas eventually fall within the scheme. It is also one of the features critics have questioned, arguing that frequent rotation can weaken the incentive for a sitting member to nurture a constituency.
The two words that decide when this reform becomes real are census and delimitation. A census is the decennial population count. Delimitation is the redrawing of constituency boundaries and the fixing of the number of seats, carried out by an independent Delimitation Commission on the basis of census data. Article 334A says the women’s reservation shall take effect after a delimitation carried out on the first census taken after the amendment came into force. Because the reserved seats have to be identified constituency by constituency, and rotation depends on that map, the drafters tied the switch-on to a delimitation exercise rather than to a fixed calendar date.
Many readers know that women already hold reserved seats in panchayats and municipalities. That reservation, created by the 73rd and 74th Amendments in 1992, works differently. It applies at the level of local self-government, was implemented directly once states framed the necessary laws, and in many states the quota has since been raised to one-half. The parliamentary reservation, by contrast, applies to the Lok Sabha and the assemblies, and is bound to the census-and-delimitation condition. Both share the same one-third starting point, but they sit at different levels of India’s democracy and follow different implementation paths.
The idea of reserving a third of seats for women did not begin in Parliament. It began in the panchayats. The 73rd and 74th Amendments of 1992 put roughly a million women into local office and, over three decades, normalised the sight of women running village councils and municipal wards. That local experience became one of the strongest arguments made in favour of extending the same principle to the Lok Sabha and the assemblies — a case built not on theory but on lived precedent.

Newest first. Tags mark the nature of each milestone.
Historical background. Two and a half years after enactment, the reservation still had not switched on, because its trigger — census and delimitation — had not been carried out. The government moved to break the deadlock.
What happened. On 16 April 2026, a gazette notification brought the 106th Amendment into force. The same day, the Constitution (131st Amendment) Bill sought to let Parliament use the 2011 Census for delimitation and to raise the Lok Sabha ceiling to 850 seats, alongside a Delimitation Bill and a Union Territories laws bill. On 17 April 2026, the amendment bill was defeated, recording 298 votes for and 230 against, short of the special majority; the companion bills were withdrawn.
Political context. The 2024 general election was the first held after the 106th Amendment was passed, but well before any reservation could apply. It therefore ran entirely on the existing, unreserved seats.
Impact on representation. Voters returned 74 women to the 543-member Lok Sabha, about 13.6 percent — a slight dip from the roughly 14.4 percent elected in 2019. The number underlined the gap the reservation is meant to address, and the fact that, for now, change still depends on parties fielding and voters electing women rather than on any quota.
Parliamentary development. In a special session, and as the first bill taken up in the new Parliament building, the government introduced the Constitution (128th Amendment) Bill, titled the Nari Shakti Vandan Adhiniyam. The Lok Sabha passed it on 20 September 2023 with 454 votes in favour and 2 against; the Rajya Sabha passed it unanimously on 21 September with 214 votes in favour and none against.
Constitutional significance. President Droupadi Murmu gave assent on 28 September 2023, and it was enacted as the Constitution (106th Amendment) Act, 2023. After decades of failed attempts, the reservation was finally written into the Constitution — though with the census-and-delimitation condition built into its text.
Historical background. The UPA government had reintroduced the reservation as the Constitution (108th Amendment) Bill in 2008, placing it in the Rajya Sabha so it would not lapse with the lower house. After a committee examination, it came to a vote.
Parliamentary development. On 9 March 2010, the day after International Women’s Day, the Rajya Sabha passed the bill, with the voting recorded overwhelmingly in favour. But the Lok Sabha never took it up. With the dissolution of the 15th Lok Sabha in 2014, the bill lapsed, its Rajya Sabha passage notwithstanding.
Political context. The reservation had been part of the UPA’s Common Minimum Programme. To protect it from the fate of earlier versions, the government introduced it in the Rajya Sabha, a permanent house that is not dissolved, and referred it to the Parliamentary Standing Committee on Law and Justice for scrutiny.
Constitutional significance. The 2008 draft became the template that would eventually shape the 2023 law, including the one-third figure and the reservation-within-reservation for SC and ST women. Disagreement persisted, however, over demands for a separate sub-quota for OBC and minority women.
Political context. Through the NDA years, the reservation was placed before Parliament more than once, including twice in 2003. Each attempt ran into the same wall: parties that supported reservation in principle split over whether it should carve out a separate quota for women from OBCs and minorities.
Impact on women’s participation. The stalemate meant the promise stayed on paper while women’s share of the Lok Sabha remained low, hovering around a tenth of seats through this period.
Parliamentary development. The newly formed NDA government brought the reservation back before the House. The debates were passionate and, at times, disorderly, reflecting how deeply the sub-quota question divided members even within governing coalitions.
Constitutional significance. Although it did not pass, the 1999 attempt kept the reservation on the national agenda and set up the more structured push that would follow in 2008.
Historical background. The Vajpayee-led government reintroduced the reservation in 1998. The session became notorious for scenes of disruption on the floor as the bill was tabled, a vivid illustration of how contested the measure had become.
Constitutional significance. Like its predecessor, the bill could not secure passage and lapsed. Yet the repeated attempts steadily built a record of parliamentary intent that later governments would cite.
Parliamentary development. The United Front government led by H. D. Deve Gowda introduced the Constitution (81st Amendment) Bill, the first formal attempt to reserve one-third of Lok Sabha and assembly seats for women. It was referred to a Joint Parliamentary Committee chaired by Geeta Mukherjee, whose report shaped later drafts.
Constitutional significance. The bill lapsed with the dissolution of the 11th Lok Sabha in 1997, but it established the template — one-third reservation, applied to the directly elected houses — that every subsequent version would build on.
Historical background. Parliament passed the 73rd and 74th Constitutional Amendments in 1992, giving constitutional status to panchayats and municipalities. They came into force in 1993.
Constitutional significance. Both amendments mandated that at least one-third of seats — and of chairperson positions — in rural and urban local bodies be reserved for women. This was the first time the one-third principle entered the Constitution, and it created the grassroots precedent that advocates would invoke for decades.
Constitutional significance. The Constitution of India granted universal adult suffrage from the outset, giving women the vote on equal terms with men — a rarity among newly independent nations. It guaranteed equality before the law and empowered the state to make special provisions for women and children.
Impact on women’s participation. Equal voting rights were foundational, but they did not translate into equal presence in legislatures. Women made up only a small fraction of the first Lok Sabha, exposing the gap between the right to vote and the reality of being elected.
Historical background. The Constituent Assembly that framed the Constitution included pioneering women members such as Sarojini Naidu, Vijaya Lakshmi Pandit, Hansa Mehta, Rajkumari Amrit Kaur, Durgabai Deshmukh, Renuka Ray and Begum Aizaz Rasul.
Constitutional significance. The Assembly debated whether to reserve seats for women and largely chose equality without quotas, with several women members themselves arguing that reservation could be seen as a mark of weakness rather than empowerment. That founding choice framed the reservation debates that would resurface half a century later.
Historical background. The Government of India Act, 1935 widened the electorate and, for the first time, provided a limited number of reserved seats for women in the provincial legislatures, though the franchise itself remained restricted by property and education qualifications.
Constitutional significance. This was the colonial-era precedent for reserved women’s seats in India, a partial and unequal measure that nonetheless established that reservation was administratively possible.
Historical background. In 1917, the Women’s Indian Association was founded in Madras, and in December a delegation led by Sarojini Naidu met the Secretary of State for India, Edwin Montagu, and the Viceroy to press for women’s franchise.
Constitutional significance. The immediate reforms did not grant the demand, leaving the question of women voting to the provinces. But the delegation marked the organised beginning of the campaign for women’s political rights in India — the first thread in a story that runs all the way to the Nari Shakti Vandan Adhiniyam.
The reservation cannot simply be declared for a third of existing seats, because the law requires specific constituencies to be identified and rotated. That identification is the job of a Delimitation Commission, which works from fresh census figures. By binding the reservation to delimitation, Article 334A ensures the reserved seats are mapped systematically — but it also means the reform waits on two large administrative exercises the government must first set in motion. The condition is legal design, not a mere formality.
The constitutional sequence from enactment to a reserved seat, step by step.
Parliament passes the amendment by special majority and the President gives assent. Completed on 28 September 2023, making it the 106th Amendment.
The government notifies the Act into force through a gazette notification. Completed on 16 April 2026. This starts the clock but reserves no seats on its own.
The first census taken after commencement is conducted and its figures published. This provides the population data on which the next steps depend.
An independent Delimitation Commission redraws constituencies and identifies which seats will be reserved for women, using the census data.
One-third of the directly elected seats, including within SC and ST seats, are reserved for women. Reserved constituencies rotate after each subsequent delimitation.
Steps one and two are done: the Act is enacted and in force. Steps three, four and five are pending and depend on government decisions and, potentially, further legislation. The 2026 attempt to let the 2011 Census substitute for a fresh count was defeated, so the requirement of a census taken after commencement, followed by delimitation, remains the operative route.

India has reserved seats for women in local government for over thirty years. Under the 73rd and 74th Amendments the floor is one-third, but a majority of states have gone further and reserved half of all panchayat and municipal seats for women — putting well over a million women into elected local office at any given time. That grassroots reality is far ahead of the national legislature, where women still hold under one-seventh of Lok Sabha seats.
The institutions and provisions that define the reservation.
The Constitution (106th Amendment) Act, 2023, which reserves one-third of directly elected seats for women in the Lok Sabha and state assemblies.
The three articles inserted by the amendment: reservation in the Lok Sabha, in the assemblies and Delhi, and the timing and rotation rules.
The Lok Sabha and Rajya Sabha, which together passed the amendment in September 2023 with near-unanimous support.
President Droupadi Murmu gave assent to the amendment on 28 September 2023, completing its enactment.
The independent body that redraws constituencies using census data; the reservation takes effect only after a delimitation on the first census after commencement.
The authority that conducts elections to the reserved and general seats once the reservation is operational.
It is tempting to read the 106th Amendment as a single 2023 event. The fuller truth is that it is the accumulation of nearly three decades of parliamentary effort — the 1996 bill, the 1998 and 1999 reintroductions, the 2008 draft, the 2010 Rajya Sabha passage — layered on a century-old campaign for women’s political rights. The law reflects consensus-building over time far more than any one government’s decision.

Thirty-five questions on the law, its history and its implementation.
The Women’s Reservation Bill is often narrated as a single triumphant moment in September 2023. Read across a longer horizon, it is something more interesting: the record of a democracy arguing with itself for a century about who gets to sit in the room where laws are made. The thread runs from a 1917 delegation asking for the vote, through a Constituent Assembly that chose equality over quotas, to the panchayats of 1992 that proved the one-third idea could work, and finally to the near-unanimous votes of 2023 that wrote it into the national legislature.
What the 106th Amendment settles is the principle. One-third of the directly elected seats in the Lok Sabha and the assemblies are now constitutionally promised to women, including within the seats reserved for Scheduled Castes and Scheduled Tribes. That is a genuine constitutional milestone, and it commands a breadth of cross-party agreement that eluded every earlier attempt.
What it does not yet settle is the practice. By tying the reservation to a census and a delimitation exercise, the law defers its own effect, and the events of April 2026 — the Act notified into force, the fast-track amendment defeated — show that the path from promise to reserved seat still runs through decisions Parliament and the government have to make. Scholars and policymakers continue to debate the timing, the proposal for an OBC sub-quota, and what a larger Lok Sabha would mean for the balance between states.
That is why this timeline keeps the enacted law and the pending steps in separate columns. The reservation is real as constitutional text and, for now, deferred as electoral reality. Its long-term impact on India’s democracy will be measured not on the day it was passed, but on the day the first third of seats is actually contested by, and reserved for, women.
