Electoral Systems: FPTP for Lok Sabha vs Proportional Representation for Rajya Sabha

Electoral system comparison is essential to understanding why India's two Houses of Parliament are constituted so differently: the Lok Sabha is directly elected by the entire adult population through the First-Past-the-Post (FPTP) method, while the Rajya Sabha is indirectly elected using a form of proportional representation. The two methods reflect the different roles the Constitution assigns to each House — one a direct mirror of the electorate, the other a chamber representing the states.

How the Lok Sabha Is Elected: First-Past-the-Post

The Lok Sabha is elected directly by the people through universal adult suffrage. The country is divided into 543 territorial constituencies, each electing a single member, which makes every constituency a single-member constituency. Under FPTP, the candidate who secures the highest number of votes in that constituency wins, regardless of whether that is an outright majority of votes cast. Before every election, an Electoral Roll is prepared to identify all eligible voters, and every citizen aged 18 or above can vote irrespective of caste, religion, or gender. The Lok Sabha's normal term is five years, though it can be dissolved earlier.

How the Rajya Sabha Is Elected: Proportional Representation by Single Transferable Vote

The Rajya Sabha represents the states and is not directly elected by the people at all. Its members are elected by the elected members of the respective State Legislative Assemblies, using the single transferable vote (STV) variant of proportional representation — one of two broad forms of PR, the other being the list system, which India has not adopted for any of its elections. Under STV, each MLA-voter ranks candidates in order of preference, and a candidate must cross a quota calculated from the total votes polled divided by the number of seats to be filled plus one, with one added to that result. For example, if 200 MLAs in a state are electing 4 Rajya Sabha members, the winning quota works out to 41 votes. Rajya Sabha members serve six-year terms, with one-third of the membership retiring every two years, giving the House a permanent, non-dissolvable character unlike the Lok Sabha.

Why the Constituent Assembly Chose FPTP for the Lok Sabha

Some members of the Constituent Assembly had favoured proportional representation for the Lok Sabha as well, but the Constitution ultimately did not adopt it for the directly elected House, for two broad reasons: PR is a comparatively complex system for voters to follow, which was seen as a real obstacle given the country's literacy levels at the time, and it was considered less suited to a parliamentary form of government, where a workable single-party or coalition majority in the House is important for a stable executive. FPTP, by contrast, tends to convert even a modest lead in votes into a clear majority of seats, which suits the requirement of a parliamentary system that the Council of Ministers command a working majority in the Lok Sabha.

The Disproportionality Problem: 1977 and 1984 in Numbers

The trade-off for that stability is that FPTP does not translate vote share into seat share proportionally, and can under-represent smaller or geographically spread-out groups. Two general elections illustrate this sharply. In 1977, the Congress party was defeated in a Lok Sabha election for the first time, winning only 154 seats with less than 35 percent of the vote, while the Janata Party and its allies won 330 of 542 seats (295 of them by the Janata Party alone) on the strength of a wave that swept north India, even though Congress still did comparatively well in the south. In 1984, the pattern ran the other way: Congress won about 48 percent of the vote but close to 80 percent of the seats, while the BJP secured 7.4 percent of the vote but less than 1 percent of the seats — a striking demonstration of how FPTP can turn a moderate vote share into an overwhelming seat majority, or leave a meaningful vote share almost unrepresented.

Reservation of Seats for SC/ST

Within the FPTP framework, the Constitution reserves Lok Sabha seats for Scheduled Castes and Scheduled Tribes in proportion to their population, with 84 seats currently reserved for SCs and 47 for STs out of the House's total strength of 543. The same principle of proportional reservation extends to state legislative assemblies and, for women, to one-third of seats in rural and urban local bodies.

Composition Beyond Election: Nominated Members and Union Territories

The Rajya Sabha's composition includes a further departure from direct, population-based representation: the President nominates twelve members chosen for their special knowledge or experience in literature, art, science, or social service, a category with no equivalent among the Lok Sabha's elected members. Union Territories, unlike states, mostly have no representation in the Rajya Sabha at all — of eight Union Territories, only three (Delhi, Puducherry, and Jammu & Kashmir) send members, because the populations of the remaining five are too small to support a seat. The Lok Sabha's maximum strength is constitutionally fixed at 550 (530 representatives of the states and the rest from Union Territories), though its actual current strength of 543 has remained unchanged since 1971 pending fresh delimitation.

Electoral Method and the Powers Gap Between the Houses

The difference in electoral method is closely tied to the difference in powers between the two Houses. Because the Lok Sabha is directly elected, it alone holds certain powers central to parliamentary accountability, including the exclusive right to pass a no-confidence motion against the Council of Ministers, which is collectively responsible only to the Lok Sabha and not to the Rajya Sabha. Money Bills, governed by the special procedure under Article 109 and defined under Article 110, can be introduced only in the Lok Sabha; the Rajya Sabha may recommend changes but cannot reject or amend a Money Bill on its own authority, and any Rajya Sabha suggestions require the Lok Sabha's acceptance. The Rajya Sabha does retain a distinct set of powers tied to its role as representative of the states, including the ability to authorise Parliament to legislate on a State List subject, to approve the creation of new All-India Services, and to initiate the removal of the Vice-President.

UPSC Relevance

• Prelims: Frequently tested facts include the number of Lok Sabha constituencies (543), the STV quota formula, the SC/ST reserved-seat numbers, and the 1977/1984 election data as illustrations of FPTP outcomes.
• Mains: A recurring GS2 theme is evaluating whether FPTP serves Indian democracy well — its stability benefits versus its disproportionality — and how the indirect, PR-based election of the Rajya Sabha justifies its more limited powers compared to the Lok Sabha.

FAQ

Q1. What electoral system does India use for the Lok Sabha? First-Past-the-Post, in single-member territorial constituencies, where the candidate with the most votes in each constituency wins.

Q2. What electoral system does India use for the Rajya Sabha? Proportional representation by means of the single transferable vote, with MLAs of each state as the electorate.

Q3. Why wasn't proportional representation adopted for the Lok Sabha? The Constituent Assembly considered PR too complex for voters given contemporary literacy levels, and less suited to the stability a parliamentary system needs from its directly elected House.

Q4. How does FPTP cause a mismatch between votes and seats? Because only the top vote-getter in each constituency wins, a party can convert a modest vote share into a large seat majority (Congress in 1984) while another party's spread-out vote share yields very few seats (BJP in 1984).

Q5. How many Rajya Sabha seats do Union Territories get? Only three Union Territories — Delhi, Puducherry, and Jammu & Kashmir — have Rajya Sabha representation; the rest are too small in population.

Quick Revision

• Lok Sabha: FPTP, 543 single-member constituencies, direct universal adult suffrage, 5-year term.
• Rajya Sabha: PR by single transferable vote, elected by state MLAs, 6-year term with 1/3 retiring every 2 years.
• 84 SC + 47 ST seats reserved in the Lok Sabha, out of 543.
• 12 Rajya Sabha members nominated by President (literature, art, science, social service).
• 1977: Congress lost with <35% votes; 1984: Congress won 48% votes but ~80% seats — FPTP disproportionality in action.
• Money Bills: Lok Sabha only (Articles 109-110); no-confidence motion: Lok Sabha only.
