1. Composition and Election of State Legislative Assemblies (basic)
The
Legislative Assembly (also known as the
Vidhan Sabha) is the popular house of the State Legislature, much like the Lok Sabha is to the Parliament. It is composed of representatives who are
directly elected by the people of the state on the basis of
universal adult franchise. This means every citizen aged 18 or older has the right to vote, ensuring the assembly truly reflects the will of the people
Indian Polity, M. Laxmikanth, State Legislature, p.335.
The Constitution sets specific boundaries for the size of these assemblies to balance effective governance with fair representation. Generally, the maximum strength is fixed at 500 and the minimum strength at 60. However, because India is a land of diverse geography and population density, there are several exceptions for smaller states to ensure they have functional legislatures. For example, while the floor is usually 60, states like Arunachal Pradesh, Sikkim, and Goa have a minimum limit of 30 seats Indian Polity, M. Laxmikanth, State Legislature, p.335.
| State Category |

| General States |
60 |
| Mizoram |
40 |
| Nagaland |
46 |
| Arunachal Pradesh, Sikkim, Goa |
30 |
An important procedural detail in these elections involves the security deposit. To discourage non-serious candidates, every person contesting an election must deposit a certain sum. Under the Representation of the People Act, if a candidate fails to secure at least one-sixth (1/6th) of the total valid votes polled, their deposit is forfeited to the treasury. Interestingly, in a highly fragmented multi-cornered contest, it is mathematically possible for a winner to be declared even if they fail to reach this 1/6th threshold, though they would still lose their deposit!
Key Takeaway The Legislative Assembly's strength ranges from 60 to 500 (with specific exceptions for small states), and members are chosen through direct elections where winning requires a plurality of votes.

2. The First Past the Post (FPTP) Electoral System (basic)
The
First Past the Post (FPTP) system, also known as the
Plurality System, is the bedrock of direct elections in India, including those for the State Legislative Assembly. In this system, the entire state is divided into smaller geographical units called
constituencies. Each constituency elects one representative. The beauty of FPTP lies in its simplicity: the candidate who secures even a single vote more than their closest rival is declared the winner. As noted in
Indian Constitution at Work, Chapter 3, p.57, the winning candidate does
not need to secure a majority (more than 50%) of the total votes; they simply need to be ahead of everyone else in the race.
Because of this 'winner-takes-all' approach, FPTP often creates a gap between a party's share of votes and its share of seats. For instance, a party might win a seat with only 25% of the total votes if the remaining 75% is split among many other candidates. This simplicity is why India chose it over more complex systems like
Proportional Representation (PR), which is used for indirect elections like the Rajya Sabha
Indian Constitution at Work, Chapter 3, p.60. FPTP is designed to be easily understood by every voter, requiring no specialized knowledge of complex calculations.
| Feature |
First Past the Post (FPTP) |
Proportional Representation (PR) |
| Constituency |
Small geographical units (Single-member) |
Large areas or the whole country |
| Winner Criteria |

Candidates win in proportion to votes polled |
| Majority |
Not required (e.g., can win with 30% votes) |

While FPTP generally encourages a
two-party system globally, India's experience has been unique. Initially, it facilitated one-party dominance, but since 1989, it has evolved to accommodate multi-party coalitions
Indian Constitution at Work, Chapter 3, p.63. One interesting technicality is the
security deposit: under the Representation of the People Act, a candidate must secure at least
one-sixth (1/6th) of the total valid votes polled. If they fail to do so, their deposit is forfeited. In a heavily fragmented (multi-cornered) contest, it is theoretically possible for a winner to be declared even if they secure less than this 1/6th threshold, though they would lose their deposit in the process!
Key Takeaway Under FPTP, victory is determined by plurality (having the most votes) rather than an absolute majority (50% + 1).

3. The Representation of the People Act (RPA), 1951 (intermediate)
While the Constitution of India provides the fundamental framework for elections, it leaves the granular details of how an election is actually 'run' to Parliament. This led to the creation of two vital pieces of legislation. Think of the
Representation of the People Act (RPA), 1950 as the 'Setup Phase'—it deals with the allocation of seats and the preparation of electoral rolls. In contrast, the
Representation of the People Act, 1951 is the 'Action Phase.' It provides the actual machinery for conducting elections to the Houses of Parliament and the State Legislatures
Indian Polity, M. Laxmikanth(7th ed.), Election Laws, p.579.
The RPA 1951 is essentially the rulebook for candidates and political parties. It details the qualifications and disqualifications for membership (such as being found guilty of certain crimes), the procedure for the registration of political parties, and the definition of corrupt practices (like bribery or appealing to communal sentiments). Most importantly for a functioning democracy, it outlines the legal process for resolving election disputes through election petitions Indian Polity, M. Laxmikanth(7th ed.), Election Laws, p.579.
One fascinating aspect of the RPA 1951 is the Security Deposit. To ensure that only serious contenders enter the fray, every candidate must deposit a specific sum of money. If a candidate fails to secure at least one-sixth (1/6) of the total valid votes polled in the constituency, their deposit is 'forfeited' or lost to the government Indian Constitution at Work, Political Science Class XI (NCERT 2025 ed.), Chapter 3, p.62. Interestingly, in a multi-cornered contest where many candidates split the vote, it is statistically possible (though rare) for a winner to be declared even if they secured less than one-sixth of the total votes—meaning the winner themselves could technically lose their deposit!
| Feature | RPA 1950 (The Foundation) | RPA 1951 (The Conduct) |
|---|
| Focus | Voters and Constituencies | Candidates and Procedures |
| Key Tasks | Delimitation, Electoral Rolls | Voting, Counting, Disqualifications |
| Purpose | Who can vote and where? | How is the winner decided fairly? |
Remember RPA 1950 = Preparation (Mapping & Rolls); RPA 1951 = Performance (Candidates & Conduct).
Key Takeaway The RPA 1951 is the primary law governing the actual conduct of elections, setting the rules for candidate eligibility, ethical campaigning, and the 1/6th vote threshold for security deposits.

4. Candidate Qualifications and Disqualifications (intermediate)
To serve in a State Legislative Assembly, a person must navigate two sets of criteria: Constitutional requirements and Statutory (legal) requirements. Think of these as the 'eligibility' and the 'conduct' hurdles. Under Article 173 of the Constitution, a candidate must be a citizen of India, take an oath of allegiance, and meet the minimum age requirement—25 years for the Legislative Assembly and 30 years for the Legislative Council D. D. Basu, Introduction to the Constitution of India, The State Legislature, p.283.
Beyond these basics, the Parliament has the power to add more conditions via law. The most critical law here is the Representation of the People Act (RPA), 1951. This Act introduces rigorous disqualifications, such as being convicted of an offense resulting in two or more years of imprisonment, failing to lodge election expenses on time, or having a personal interest in government contracts or works M. Laxmikanth, Indian Polity, State Legislature, p.338. Interestingly, while the Governor decides on disqualifications under the Constitution (in consultation with the Election Commission), the High Court handles disputes regarding the validity of an actual election.
A unique financial aspect of candidacy is the Security Deposit. Every candidate must deposit a specific sum (currently ₹10,000 for the Assembly, with concessions for SC/ST candidates) to ensure only serious contenders participate. A candidate forfeits this deposit if they fail to secure at least one-sixth (1/6th) of the total valid votes polled in the constituency. Usually, the winner easily clears this bar. However, in a multi-cornered contest where many strong candidates split the vote significantly, it is mathematically possible for a winner to be elected with a very small plurality—potentially even less than 16.67% of the total vote. In such a rare case, the individual would become an MLA but still lose their deposit!
Key Takeaway Qualifications are set by both the Constitution and the RPA 1951; a candidate must secure more than 1/6th of the valid votes to save their security deposit, a rule designed to discourage non-serious candidates.

5. Powers and Role of the Election Commission of India (intermediate)
To understand the functioning of a State Legislative Assembly, we must first look at the 'referee' that makes the game possible: the
Election Commission of India (ECI). Under
Article 324 of the Constitution, the ECI is granted the power of
superintendence, direction, and control of the entire process of conducting elections. This isn't just a administrative duty; it is a constitutional mandate to ensure that the will of the people is recorded fairly and without interference from the government in power.
Indian Constitution at Work, Chapter 3, p.68. In the context of the State Legislature, while the assembly is a state body, the ECI is a centralized, independent authority that ensures uniform standards across the country.
The powers of the Commission are remarkably broad and are generally classified into three functional pillars:
| Category |
Core Responsibility |
Example |
| Administrative |
Managing the logistics and machinery of the election. |
Determining territorial constituencies based on Delimitation Commission Acts and enforcing the Model Code of Conduct. |
| Advisory |
Guiding constitutional heads on legal entanglements. |
Advising the Governor on matters relating to the disqualifications of members of the State Legislature. |
| Quasi-Judicial |
Acting as a court for specific electoral disputes. |
Settling disputes regarding the recognition of political parties and the assignment of election symbols. |
Laxmikanth, Chapter 42, p.421
It is a common misconception that the ECI works alone. At the state level, the election work is supervised by the Chief Electoral Officer (CEO), who is an officer of the state government nominated by the ECI. However, the CEO remains under the direct 'superintendence and control' of the ECI, ensuring that the local administration remains neutral during the heat of an assembly election. Laxmikanth, Chapter 66, p.573. This structure creates a system of checks and balances, where the independent judiciary and the commission can prevent the executive from overstepping its bounds during the democratic process. Exploring Society, Chapter 10, p.154.
Key Takeaway The Election Commission of India is an independent constitutional body that manages elections for Parliament, State Legislatures, and the President/Vice-President, using administrative, advisory, and quasi-judicial powers to ensure fairness.

6. Nomination Process and Security Deposits (exam-level)
To ensure that elections are contested by serious contenders, the law requires every candidate to undergo a formal
nomination process. A candidate must file their nomination papers with the
Returning Officer (RO). For a candidate to be validly nominated for the State Legislative Assembly, their name must be proposed by registered electors of the constituency. In a recognized political party, one proposer is enough; however, independent candidates or those from unrecognized parties usually require ten proposers
Indian Polity, M. Laxmikanth(7th ed.), Electoral Reforms, p.587.
Along with the nomination papers, candidates must pay a
security deposit. This serves as a 'seriousness' fee to prevent a multiplicity of non-serious candidates from cluttering the ballot. Currently, for the State Legislative Assembly, a general candidate must deposit
₹10,000, while candidates belonging to
Scheduled Castes (SC) or Scheduled Tribes (ST) pay a concessional amount of
₹5,000 Indian Polity, M. Laxmikanth(7th ed.), Electoral Reforms, p.587.
The most critical rule regarding this deposit is its
forfeiture. A candidate's deposit is returned if they are elected or if they poll more than
one-sixth (1/6th) of the total valid votes polled in the constituency. If they fail to reach this 1/6th threshold, the money is forfeited to the government treasury. Interestingly, in a
multi-cornered contest where many candidates divide the vote share, it is mathematically possible for a winner to be declared even if they secured less than 1/6th of the total votes. In such a rare case, even the winner would lose their security deposit!
Key Takeaway The security deposit (₹10,000 for Assembly) is forfeited if a candidate fails to secure more than 1/6th of the total valid votes polled, a mechanism designed to discourage non-serious candidates.

7. The 'One-Sixth' Rule and Forfeiture of Deposit (exam-level)
In the vibrant democracy of India, elections often see a high number of candidates. To ensure that only 'serious' contenders participate and to prevent the ballot from being cluttered by non-serious individuals, the law mandates a
Security Deposit. According to the
Representation of the People Act, 1951, every candidate contesting an election to the State Legislative Assembly or Parliament must deposit a specific sum of money with the Election Commission. For the
State Legislative Assembly, this amount is currently ₹10,000 for general candidates and ₹5,000 for SC/ST candidates
Indian Polity, M. Laxmikanth, Electoral Reforms, p.586.
The most critical aspect of this deposit is the
'One-Sixth' Rule. A candidate is entitled to a refund of their deposit only if they manage to secure
more than one-sixth (approx. 16.67%) of the total
valid votes polled in the constituency. If a candidate fails to reach this threshold, their deposit is 'forfeited'—meaning it is credited to the government treasury and not returned. This rule serves as a mathematical benchmark for political relevance in a specific contest
Indian Polity, M. Laxmikanth, President, p.189.
Interestingly, it is statistically possible (though rare) for a candidate to
win the election but still lose their deposit. This happens in a
multi-cornered contest where the vote share is so heavily split among dozens of candidates that even the person with the highest number of votes (the winner) fails to cross the 16.67% mark. Since India follows the 'First-Past-The-Post' system, the person with the most votes wins, regardless of whether they met the one-sixth threshold required to save their deposit
Indian Polity, M. Laxmikanth, Elections, p.576.
Key Takeaway The security deposit is forfeited if a candidate fails to secure more than 1/6th of the total valid votes polled, a rule designed to discourage non-serious candidates from contesting.

8. Solving the Original PYQ (exam-level)
To solve this question, you must synthesize two fundamental concepts: the First-Past-The-Post (FPTP) system used in State Legislative Assemblies and the statutory rule regarding the security deposit. As you have learned, according to the Representation of the People Act (and as noted in Indian Polity, M. Laxmikanth), a candidate must secure more than one-sixth (16.67%) of the total valid votes polled to avoid forfeiting their deposit. In an FPTP system, a candidate only needs to secure more votes than any other individual contestant to win; there is no requirement to secure a majority or even a specific minimum percentage of the total vote.
The logic follows that if an elected candidate loses their deposit, their total vote share must be less than 16.67%. For a winner to have such a low percentage, the total pool of votes must be incredibly fragmented across a multitude of contestants. Therefore, the only plausible scenario is that (D) a very large number of candidates contested the election, causing the vote share to split so significantly that even the person at the top of the list failed to reach the one-sixth threshold. This highlights a quirk of our electoral system where "representation" can sometimes occur with very low mandates if the field is overcrowded.
As a UPSC aspirant, you must avoid common traps found in the distractors. Option (A) is a trap because the 1/6th rule is a ratio of total votes cast, not an absolute number; if only 100 people vote, you still need 17 votes to save your deposit. Option (C) is a frequent point of confusion—a victory can be "marginal" (won by only a few votes) even if both candidates secure 40% of the vote, which is well above the deposit threshold. Finally, as discussed in Indian Constitution at Work (NCERT), India moved away from multi-member constituencies (Option B) shortly after the first general elections, making it irrelevant to modern Assembly contests.
