1. Introduction to Electoral Systems: FPTP vs. PR (basic)
To understand how our State Legislative Assemblies are formed, we must first look at the
First-Past-The-Post (FPTP) system. Imagine a race where the runner who crosses the finish line first wins, regardless of how close the others are behind them. In electoral terms, this is known as the
Plurality System. Under this method, the entire state is divided into geographical units called
single-member constituencies. Each area elects exactly one representative. The candidate who secures more votes than any other individual rival is declared the winner, even if they do not secure a majority (more than 50%) of the total votes cast
Indian Constitution at Work, NCERT Class XI (2025 ed.), Chapter 3, p. 57.
The alternative to this is
Proportional Representation (PR). While FPTP is used for direct elections to the Lok Sabha and State Assemblies, our Constitution reserves PR for indirect elections, such as those for the Rajya Sabha or the State Legislative Councils
Indian Polity, M. Laxmikanth(7th ed.), Chapter 23, p. 225. In a PR system, a party usually gets a share of seats in the legislature that is strictly proportional to its share of the total votes. In contrast, FPTP often leads to
voter-seat distortion, where a party might win a landslide victory in terms of seats (say 70%) while only securing a plurality of the popular vote (say 40%).
The table below summarizes the core differences between these two foundational systems:
| Feature | First-Past-The-Post (FPTP) | Proportional Representation (PR) |
|---|
| Winner's Requirement | Highest number of votes (Plurality) | Proportion of total votes received |
| Constituency | Small geographical units (Single-member) | Large areas/Entire country (Multi-member) |
| Voter Choice | Voter chooses a specific candidate | Voter often chooses a party list |
| Representation | May not represent the whole electorate | Provides representation to smaller parties |
Key Takeaway In the FPTP system used for State Assemblies, a candidate wins by securing a plurality of votes (more than anyone else), which often results in a party's seat share being much higher than its actual vote share.

2. Constitutional Framework: Articles 324 to 329 (basic)
To understand how a
State Legislative Assembly is formed, we must look at the 'engine room' of Indian democracy:
Part XV of the Constitution (Articles 324 to 329). This section ensures that the process of choosing representatives is not left to the whims of the government of the day but is governed by a robust, independent framework.
M. Laxmikanth, Salient Features of the Constitution, p.37.
At the heart of this framework is
Article 324, which establishes the
Election Commission of India (ECI). This permanent, independent body is vested with the
superintendence, direction, and control of elections. A crucial distinction for your exams: while the ECI conducts elections for Parliament and
State Legislatures, it does
not handle local body elections (Panchayats and Municipalities); those are managed by a separate State Election Commission.
M. Laxmikanth, Election Commission, p.419.
Key Takeaway The Election Commission of India (ECI) is the sole authority responsible for conducting elections to the State Legislative Assemblies, ensuring the process remains free from executive interference.
The framework also establishes the
principles of representation. Under
Article 325, no person can be excluded from the electoral rolls based on religion, race, caste, or sex—ensuring a secular and inclusive electorate.
Article 326 grants
Universal Adult Suffrage, meaning every citizen above 18 has the right to vote. In our State Assemblies, we follow the
First-Past-The-Post (FPTP) system. In this 'winner-takes-all' model, the candidate with the most votes in a constituency wins, even if they don't secure an absolute majority (50% + 1). This sometimes leads to
voter-seat distortion, where a party's share of seats is much higher than its total share of votes.
NCERT Class XI, Election and Representation, p.57.
| Article | Subject Matter |
|---|
| 324 | Establishment and powers of the Election Commission. |
| 325 | No discrimination in electoral rolls (Secularism). |
| 326 | Universal Adult Suffrage (Right to vote). |
| 327 & 328 | Power of Parliament and State Legislatures to make laws regarding elections. |
| 329 | Bar to interference by courts in electoral matters (e.g., delimitation). |
Remember Article 324 is the "Store" where the power of elections is kept; Article 326 is the "Sixer" — the power of the people to hit a home run by voting!

3. Structure and Composition of State Legislative Assemblies (intermediate)
The
Legislative Assembly (Vidhan Sabha) is the cornerstone of state-level democracy in India. It is the 'Popular House,' meaning its composition is rooted in the direct will of the people. Unlike the Legislative Council, which is indirectly elected, members of the Assembly are chosen through
direct elections based on
universal adult franchise. This ensures that every adult citizen has a direct say in who represents their territorial constituency
Indian Polity, M. Laxmikanth, Chapter 33, p.335.
To maintain a balance between effective governance and fair representation, the Constitution prescribes specific limits on the size of these Assemblies. While the size varies based on the state's population, there are strict boundary conditions:
| Feature |
Constitutional Provision |
| Maximum Strength |
500 Members |
| Minimum Strength |
60 Members (General rule) |
However, the diversity of India's geography and population necessitated certain exceptions. For smaller states, the minimum strength has been lowered to ensure they have a functional legislature without being demographically overwhelmed:
- 30 Members: Arunachal Pradesh, Sikkim, and Goa.
- 40 Members: Mizoram.
- 46 Members: Nagaland.
The method used for these elections is the First-Past-The-Post (FPTP) system. In this plurality system, the state is divided into single-member territorial constituencies. The candidate who secures the highest number of votes in a constituency is declared the winner, even if they do not cross the 50% majority mark. While this system is simple and stable, it often leads to a "seat-vote gap," where a party's percentage of total seats may not perfectly match its percentage of the total popular vote Indian Polity, M. Laxmikanth, Chapter 23, p.225.
Regarding nominated members, there has been a significant legal shift. Previously, the Governor could nominate one member from the Anglo-Indian community. However, the 104th Constitutional Amendment Act (2019) discontinued this provision for both the Lok Sabha and the State Assemblies, effective from January 2020 Indian Polity, M. Laxmikanth, Chapter 33, p.335. Today, the Assembly consists entirely of elected representatives, with specific seats reserved for Scheduled Castes and Scheduled Tribes based on their population proportions.
Remember the "30-Club": Arunachal, Sikkim, and Goa (ASG) all have a minimum of 30 seats.
Key Takeaway The Legislative Assembly is a directly elected body with a population-linked strength (60-500), though smaller states have lower minimums, and nominated seats for Anglo-Indians have now been abolished.

4. Delimitation and Territorial Constituencies (intermediate)
In a healthy democracy, every citizen's vote should carry equal weight. However, as populations grow and move, some areas become more crowded while others thin out. This is where Delimitation comes in. It is the process of redrawing the boundaries of territorial constituencies (both for the Lok Sabha and the State Legislative Assemblies) to ensure that the ratio between the population of each constituency and the number of seats remains, as far as practicable, the same across the state. This is rooted in the principle of 'One Person, One Vote, One Value.'
Under Article 170 of the Constitution, the division of each State into territorial constituencies must be readjusted after every census. While Article 82 governs this for Parliament, Article 170 handles it for State Assemblies M. Laxmikanth, Election Laws, p.580. To carry out this sensitive task, Parliament establishes a Delimitation Commission. This is a high-power body whose orders have the force of law and cannot be challenged in any court of law, ensuring that the election process isn't stalled by endless litigation.
A crucial nuance in the Indian context is the "freeze" on the total number of seats. To ensure that states with successful family planning programs were not "punished" with fewer seats, the 84th Constitutional Amendment Act (2001) froze the total number of seats in the Assemblies based on the 1971 census until the first census after the year 2026 M. Laxmikanth, Delimitation Commission of India, p.530. However, while the total number of seats is frozen, the internal boundaries within a state were redrawn to account for population shifts. Following the 87th Amendment Act (2003), this internal readjustment is now based on the 2001 census figures.
Finally, it is important to understand that while Delimitation ensures geographic fairness, it does not eliminate "voter-seat distortion." In our First-Past-The-Post (FPTP) system, a candidate wins by securing more votes than any rival (a plurality), even if they don't get a majority (50%+). Consequently, a party might win a disproportionately high share of seats compared to its total vote share because of how those votes are concentrated across the redrawn constituencies NCERT Class XI, Election and Representation, p.57.
Key Takeaway Delimitation ensures each MLA represents roughly the same number of people, with total seat counts currently frozen at 1971 levels, while internal boundaries are adjusted based on the 2001 census.

5. Political Parties and the Anti-Defection Law (intermediate)
In the vibrant landscape of Indian democracy, political parties are the lifeblood of the State Legislative Assembly. However, the stability of a government often depends on the loyalty of its members. Before 1985, India witnessed a chaotic era of 'floor-crossing,' where legislators frequently switched parties for personal gain or power, leading to the infamous phrase "Aaya Ram, Gaya Ram." To curb this unethical practice and ensure political stability, the Anti-Defection Law was introduced.
The 52nd Constitutional Amendment Act of 1985 was a landmark reform that added the Tenth Schedule to the Constitution. It provides for the disqualification of members of Parliament and State Legislatures on the grounds of defection from one political party to another Indian Polity, M. Laxmikanth(7th ed.), Anti-Defection Law, p.597. Under this law, a member can be disqualified if they voluntarily give up their party membership or vote against the party's direction (the 'whip') without prior permission. This ensures that the mandate given by the voters to a specific party is respected within the House Indian Constitution at Work, Political Science Class XI (NCERT 2025 ed.), LEGISLATURE, p.120.
Over time, loopholes were identified. Initially, the law allowed a 'split' if one-third of a party's members broke away. This was often misused to facilitate mass defections. To tighten the reigns, the 91st Amendment Act of 2003 was passed. It omitted the exception for splits and mandated that at least two-thirds of the members must agree to a merger with another party to avoid disqualification Indian Polity, M. Laxmikanth(7th ed.), Anti-Defection Law, p.597. Additionally, this amendment limited the size of the Council of Ministers to 15% of the total strength of the House to prevent the practice of inducing defections with the lure of ministerial berths Indian Polity, M. Laxmikanth(7th ed.), Central Council of Ministers, p.213.
| Feature |
52nd Amendment (1985) |
91st Amendment (2003) |
| Core Purpose |
Introduced the Anti-Defection Law (10th Schedule). |
Strengthened the law and limited cabinet size. |
| Split/Merger Rule |
Recognized a 'split' if 1/3rd members left. |
Removed 'split' provision; only 'merger' (2/3rd) allowed. |
| Ministerial Limit |
No specific limit on cabinet size. |
Restricted ministers to 15% of House strength. |
The authority to decide on disqualification rests with the Presiding Officer (Speaker or Chairman) of the House Indian Constitution at Work, Political Science Class XI (NCERT 2025 ed.), LEGISLATURE, p.120. While their decision was originally intended to be final, the judiciary has since ruled that such decisions are subject to judicial review to prevent any partisan bias.
Remember
52nd = Started the law (1985); 91st = Refined the law (2003). 1/3rd was too easy to break, so they shifted to 2/3rd for mergers!
Key Takeaway
The Anti-Defection Law (Tenth Schedule) protects the stability of the State Assembly by penalizing individual floor-crossing, ensuring that legislators remain accountable to the party mandate under which they were elected.

6. Electoral Reform Committees and Recommendations (exam-level)
In any vibrant democracy, the electoral process must evolve to remain fair and representative. In India, the First-Past-The-Post (FPTP) system, while simple, often leads to voter-seat distortion—a situation where a party’s share of seats is much higher or lower than its actual share of popular votes Indian Constitution at Work, Chapter 3, p. 57. To address these systemic flaws and prevent the criminalization of politics, various governments have appointed specialized committees over the decades.
One of the most foundational groups was the Dinesh Goswami Committee (1990). Appointed by the National Front government, it tackled the "drawbacks" of the electoral system head-on. A key outcome was the classification of candidates into three categories for ballot listing: candidates of recognized political parties, candidates of registered-unrecognized parties, and independents. This was intended to provide clarity to voters and streamline the election machinery M. Laxmikanth, Electoral Reforms, p.583. Subsequent committees, such as the Indrajit Gupta Committee (1998), focused on the state funding of elections to curb the influence of "black money," while the Justice J.S. Verma Committee (2013) sought to tighten criminal laws to ensure cleaner candidacy M. Laxmikanth, Electoral Reforms, p.582.
Beyond committee reports, legislative changes in 2003 significantly altered how the Rajya Sabha (and by extension, the nature of federal representation) operates. Two major shifts occurred: first, the domicile requirement was removed, meaning a candidate no longer needs to be a resident of the specific state they wish to represent. Second, the Open Ballot System was introduced for Rajya Sabha elections to prevent "cross-voting" and ensure party discipline M. Laxmikanth, Electoral Reforms, p.585. These reforms illustrate a continuous effort to move from a system of mere "plurality" (winning with more votes than others) to one of deeper accountability and integrity.
1990 — Dinesh Goswami Committee: Proposed EVMs and state funding in kind.
1998 — Indrajit Gupta Committee: Specifically explored state funding of elections.
2003 — Rajya Sabha Reforms: Domicile requirement removed; Open Ballot introduced.
2007 — 2nd Administrative Reforms Commission: Report on Ethics in Governance (Moily Committee).
Remember
Goswami = General Reforms (EVMs, Candidate categories)
Gupta = Gold (State Funding/Money)
Verma = Violence/Crime (Criminal law amendments)

7. Alternative Voting Methods: Hare, Cumulative, and Plural Systems (intermediate)
To understand how our representatives are chosen, we must look at the mechanics of the ballot. The most common method in India is the
Plurality System, also known as
First-Past-The-Post (FPTP). In this system, the candidate who secures more votes than any other individual rival is declared the winner, regardless of whether they have a majority (50% + 1). As noted in
Indian Constitution at Work, Chapter 3: Election and Representation, p. 57, this often leads to a 'seat-vote distortion' where a party’s share of seats in the legislature is much higher than its actual share of the total popular vote. This is the primary method used for electing members to the Lok Sabha and State Legislative Assemblies.
To remedy the 'winner-takes-all' defect of FPTP, alternative systems like Proportional Representation (PR) are used. The most prominent variant in India is the Hare System, better known as the Single Transferable Vote (STV). In this system, instead of voting for just one person, voters rank candidates in order of preference. A candidate must reach a specific 'quota' of votes to be elected. If a candidate has surplus votes or if the lowest-ranking candidates are eliminated, those votes are 'transferred' to the next preference on the ballot. This system ensures that even smaller groups get their due share of representation Indian Polity, Chapter 23: Parliament, p. 225. In the context of State Legislatures, the Hare System (STV) is used by MLAs to elect members to the Rajya Sabha and the State Legislative Council.
Other specialized methods include Cumulative Voting and Plural Voting. In a Cumulative system, a voter is given multiple votes (usually equal to the number of seats available) and can 'stack' or concentrate all those votes on a single candidate. This is designed to help minority groups secure at least one representative in a multi-member district. Conversely, Plural Voting (not to be confused with Plurality) is a system where certain individuals (based on education or property) are granted more than one vote. While largely abandoned in modern democracies in favor of 'one person, one vote,' it remains a theoretical alternative in political science studies.
| System |
Core Mechanic |
Typical Outcome |
| Plurality (FPTP) |
Highest vote-getter wins; no majority needed. |
Stable majorities but high seat-vote distortion. |
| Hare (STV) |
Preferential ranking and transfer of surplus votes. |
Highly proportional; protects minority interests. |
| Cumulative |
Voters can stack multiple votes on one candidate. |
Allows small groups to win a seat via concentration. |
Key Takeaway While FPTP (Plurality) favors simplicity and stable governments, the Hare System (STV) prioritizes fairness and proportional representation, ensuring that the legislature reflects the diverse preferences of the electorate.

8. The Mechanics of Voter-Seat Distortion in FPTP (exam-level)
In the First-Past-The-Post (FPTP) system, the relationship between the percentage of votes a party receives and the number of seats it wins is rarely 1:1. This phenomenon is known as voter-seat distortion. The root of this distortion lies in the plurality principle: to win a seat in a constituency, a candidate does not need a majority (50% + 1); they simply need more votes than any other single opponent. This means that in a multi-cornered contest, a candidate can win with as little as 25% or 30% of the total votes cast in that area Indian Constitution at Work, Chapter 3, p. 57.
The mechanics of this distortion operate through two primary levers:
- The "Wasted Vote" Effect: Every vote cast for a losing candidate, as well as every vote cast for the winner beyond what they needed to beat the runner-up, does not contribute to the party's seat tally. Because only the winner takes the seat, the preferences of the remaining voters (which could be the majority) are not reflected in the assembly's composition Indian Constitution at Work, Chapter 3, p. 57.
- Geographic Concentration: If a party's support is spread thinly across the entire state, it may get a high total vote share but win zero seats because it never finishes first in any single constituency. Conversely, a party with concentrated support in specific regions can win a disproportionately high number of seats Indian Constitution at Work, Chapter 3, p. 62.
To see this in action, consider the 2016 Tamil Nadu Assembly elections. The AIADMK secured roughly 40.8% of the total votes but walked away with 135 seats (a clear majority). Meanwhile, the PMK secured over 5% of the total votes across the state—a significant number—but won zero seats because their candidates did not come first in any individual constituency Indian Constitution at Work, Chapter 3, p. 62. This "bonus" for the largest party and the "penalty" for smaller, spread-out parties is a defining characteristic of our electoral mechanics.
Key Takeaway Voter-seat distortion occurs because FPTP rewards the candidate with a relative plurality in a single-member district, effectively "discarding" the votes cast for all losing candidates.

9. Solving the Original PYQ (exam-level)
This question tests your ability to apply the foundational concept of electoral systems to real-world data. You have just learned that the hallmark of the First-Past-The-Post (FPTP) system—used in India’s Lok Sabha and State Legislative Assembly elections—is its 'winner-takes-all' nature. As highlighted in Indian Constitution at Work, this system often leads to a significant disproportionality between the percentage of votes a party receives and the number of seats it actually wins. The table provided is a textbook illustration of this: when a party's seat share is significantly higher or lower than its popular vote share, you are looking at voter-seat distortion.
To arrive at the correct answer, (C) First-past-the-post system, you must recognize that in a single-member constituency, a candidate only needs one more vote than their closest rival to win the entire seat. This means that millions of votes cast for losing candidates do not translate into representation, allowing a party with a relatively small lead in popular votes across many constituencies to sweep a massive majority of seats. This specific phenomenon is a defining characteristic of FPTP, as explained in Indian Polity by M. Laxmikanth, where the 'bonus' seats awarded to the leading party create the distortion shown in the Karnataka election data.
UPSC often uses technical-sounding alternatives to distract you. The Hare system and Cumulative vote system are actually forms of Proportional Representation designed specifically to eliminate or minimize the very distortion mentioned in the question. Similarly, a Plural vote system (where one person has multiple votes) is a historical anomaly not used in the Indian context. Therefore, by understanding that only FPTP allows for such a 'seat-vote gap,' you can confidently eliminate the other options and identify the First-past-the-post system as the causal mechanism.
