Reserved constituencies: from separate electorates to reserved seats

Detail

1. The problem: why FPTP needs a correction

• First-past-the-post (FPTP) means the candidate with the most votes in a constituency wins. They do not need a majority of the votes.
• Under FPTP, a large caste can win almost everywhere.
• In most constituencies, dominant castes have more voters.
• Their candidates win seat after seat.

• Groups that faced discrimination and live thinly spread across many constituencies may never win a seat.

• So India needed a way to make sure SCs and STs get seats in the legislatures, without dividing voters by community.

2. Colonial route: separate electorates

• Separate electorate: a system where only voters of one community vote to elect that community's representative. For example, only Muslims voted for Muslim seats.
• Timeline:
• Indian Councils Act, 1909 (Morley-Minto Reforms): separate electorates for Muslims.
• Government of India Act, 1919: extended to more communities.

• Government of India Act, 1935: extended further.

• Communal Award (1932): the British offered separate electorates to the Depressed Classes (the colonial term for today's Scheduled Castes).

• Poona Pact (1932): Gandhi and Ambedkar agreed to a different system.
• The Depressed Classes got reserved seats in a joint electorate instead of separate electorates.
• In a joint electorate, all communities vote together.

• This became the model for today's system.

• Ambedkar's critique of the Poona Pact: a reserved-seat winner needs votes from other castes. So the winner may be the SC candidate whom the dominant castes accept, not the one SC voters prefer.

3. The Constituent Assembly rejects separate electorates

• Many members felt separate electorates had helped cause Partition.
• Tajamul Husain (26 May 1949): called separate electorates "a curse to India".
• Jaipal Singh (27 August 1947): said Adivasis wanted reserved seats, not separate electorates.

• Under the 1935 Act, only 24 Adivasi MLAs out of 1,585 were elected.

• Draft Article 292 became Article 330. It was debated on 23-24 August 1949 [6].

• The Drafting Committee's amended text dropped seat reservation for Muslims and Christians. It kept reservation only for SCs and STs [6].
• The Assembly adopted this version on 24 August 1949 [6].

4. Single general electoral roll (Article 325)

• Single general electoral roll: one voters' list for each territorial constituency, shared by all voters.
• Art. 325: no person can be left off this roll, or put on a special roll, only because of religion, race, caste or sex.
• Effect: separate electorates are ruled out by the Constitution. Every voter in a reserved constituency votes from the same roll.

5. The reservation scheme

Feature	Lok Sabha	State Legislative Assembly
Article	Art. 330	Art. 332
Who is reserved for	SCs; STs (with a separate clause for STs in the autonomous districts of Assam) [6]	SCs; STs
Basis of numbers	Each state's reserved seats are in proportion to its SC/ST share of the population [6]	Same principle
Who votes	All voters on the general roll	All voters on the general roll
Who can contest	Only SC (or ST) candidates	Only SC (or ST) candidates

• Reserved constituency: a seat where every registered voter votes, but only a member of the SC (or ST) community can stand as a candidate.
• Art. 330(1) reserves Lok Sabha seats for: (a) Scheduled Castes; (b) Scheduled Tribes, except those in the autonomous districts of Assam; (c) Scheduled Tribes in the autonomous districts of Assam [6].
• Art. 330(3): the seats for STs in Assam's autonomous districts must be at least in proportion to their share of the state's population [6].
• Current numbers: 84 SC and 47 ST seats out of 543 Lok Sabha seats, leaving 412 general seats.
• No reservation in the upper houses: the Rajya Sabha and state Legislative Councils have none.
• These houses are elected indirectly: members are chosen by other elected members, not directly by voters.
• In a Lok Sabha reply on 18 July 2002, the government said it did "not think appropriate" to extend SC/ST reservation to the upper houses [5].

6. Time limit and extensions (Article 334)

• Art. 334 set reservation (and Anglo-Indian nomination) for 10 years from the start of the Constitution.
• Parliament has extended it every ten years:

Amendment	Extended up to
8th (1959)	1970
23rd (1969)	1980
45th (1980)	1990
62nd (1989)	2000
79th (1999)	2010
95th (2009)	2020
104th (2019)	25 January 2030

• 104th Amendment, 2019 (passed as the Constitution (126th Amendment) Bill, 2019):
• Introduced in the Lok Sabha on 9 December 2019. Passed by the Lok Sabha on 10 December 2019 and by the Rajya Sabha on 12 December 2019 [2].
• The earlier limit was 25 January 2020. SC/ST reservation now runs to 25 January 2030 [2].
• Anglo-Indian nomination came under Art. 331 (Lok Sabha) and Art. 333 (state assemblies) [2]. The amendment did not extend it, so it ended in January 2020.

7. How reserved seats are chosen (delimitation)

• Delimitation: redrawing the boundaries of constituencies. An independent Delimitation Commission does this work.
• Step 1, each state's quota: the Commission fixes each state's number of SC and ST seats by its SC/ST share of the population.
• Step 2, ST seats: these are placed in the constituencies where the ST share of the population is the largest [4].
• Step 3, SC seats: these go where the SC share is comparatively large, but they are spread across different parts of the state [4]. This is because SCs live dispersed, not grouped in one area.
• Step 4, rotation: the list of reserved seats can change at each delimitation.
• Legal base: s.9(1) of the Delimitation Act, 2002. It also requires seats to be single-member territorial constituencies, meaning each constituency elects one member [4].
• Delimitation Bill, 2026: introduced in the Lok Sabha on 16 April 2026 [3].
• It would repeal the Delimitation Act, 2002 [3].
• It keeps the same rules for placing SC and ST seats [3].
• It would use the latest census whose figures are published when the Commission is set up [3].
• The Commission would also decide which seats are reserved for women [3].
• A Supreme Court judge would chair the Commission [3].

8. Debates

• Dependence on non-SC votes: in a joint electorate, reserved-seat winners need votes from other castes. This continues Ambedkar's critique of the Poona Pact.
• Muslim representation: Muslims have no reserved seats, and their share in the legislatures is often below their share of the population. Some people demand a quota. The Constitution bars reservation on religious grounds, and the Constituent Assembly deliberately dropped it.
• Women's reservation: the 106th Amendment, 2023 reserves one-third of seats for women. It starts only after the next delimitation. Details are in the electoral-reforms and gender-religion-caste notes.
• SC status of converts: this is covered in the vulnerable-sections-safeguards note.

Prelims Hooks

• Art. 325: a single general electoral roll; no exclusion only because of religion, race, caste or sex.
• Art. 330 covers the Lok Sabha and Art. 332 covers state assemblies. Both reserve seats for SCs and STs in proportion to population.
• Art. 334 sets the time limit. The 104th Amendment (2019) extended it to 25 January 2030.
• The 104th Amendment ended Anglo-Indian nomination under Arts. 331 and 333. It was passed as the 126th Amendment Bill.
• 84 SC + 47 ST = 131 reserved seats out of 543 Lok Sabha seats.
• Trap: the Rajya Sabha and Legislative Councils have no SC/ST reservation.
• Delimitation Act 2002, s.9: ST seats go where the ST share is largest. SC seats go where the SC share is comparatively large, spread across the state.
• Communal Award (1932) offered separate electorates. The Poona Pact (1932) replaced them with reserved seats in a joint electorate.
• Separate electorates for Muslims began with the Indian Councils Act, 1909.
• Draft Art. 292 became Art. 330 and was adopted on 24 August 1949. The final text dropped reservation for Muslims and Christians.

Mains Points

• Joint electorate with reserved seats vs. separate electorates: reserved seats guarantee SC/ST presence without splitting voters by community. The Constituent Assembly made this choice after Partition. The cost is Ambedkar's concern: winners must please non-SC voters, which can weaken their role as true representatives.
• "Temporary" reservation, renewed seven times: Art. 334 began with a 10-year limit, but it has been renewed every decade up to 2030. This shows that the political exclusion of SCs and STs persists. It also raises the question of what evidence should decide future extensions.
• Delimitation decides who benefits: placing ST seats where STs are most numerous, and spreading SC seats across the state, affects which communities get representation. Rotation helps balance this but makes it harder for members to build ties with a constituency. The Delimitation Bill 2026 and the 106th Amendment make the next delimitation central to SC/ST and women's representation.
• Gaps in representation: there is no reservation in the Rajya Sabha or Councils, and none for Muslims (barred by Art. 325's principle and Constituent Assembly choices). Possible answers within the Constitution include party-level candidate quotas or a debate on proportional representation (PR), rather than religious quotas.
