Reserved constituencies

Also called: Reserved seats, Articles 330 and 332, Article 330, Article 332 · Topic: Elections and the Electoral System · NCERT: Class 8, Ch 5 "Universal Franchise and India's Electoral System"; Class 10, Ch 1 "Power-sharing"; Class 11, Ch 3 "Election and Representation"; Class 11, Ch 9 "Constitution as a Living Document"; Class 11, Ch 10 "The Philosophy of the Constitution"

Meaning

A reserved constituency is a Lok Sabha or state Legislative Assembly seat where every voter on the common voters' list can vote, but only a Scheduled Caste (SC) or Scheduled Tribe (ST) person can stand as a candidate (Articles 330 and 332). It guarantees that SCs and STs have members in the legislatures. It does this without splitting voters into separate groups by community.

Explanation

Why reserved seats are needed

• First-past-the-post (FPTP) means the candidate with the most votes in a constituency wins, even without a majority of the votes.
• Under FPTP, a large caste can win almost everywhere.
• Dominant castes have more voters in most constituencies.
• Their candidates win seat after seat.

• SCs and STs faced discrimination and live thinly spread across many constituencies, so they may never win a seat.

• Reserved seats correct this. They give SCs and STs a fixed share of seats.

How a reserved seat works

• Who votes: all voters on the single general electoral roll (one voters' list for each constituency, shared by everyone). This is required by Art. 325.
• Who can contest: only SC candidates in an SC seat, and only ST candidates in an ST seat.
• How many seats: each state's reserved seats are in proportion to its SC/ST share of the population [6].
• Current Lok Sabha numbers: 84 SC and 47 ST seats out of 543, so 131 are reserved and 412 are general.
• Joint electorate: a system where all communities vote together. It is the opposite of a separate electorate, where only voters of one community elect that community's member.

How reserved seats are picked (delimitation)

• Delimitation means redrawing constituency boundaries. An independent Delimitation Commission does this.
• Step 1: 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 go to 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 scattered, 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 single-member territorial constituencies, meaning each constituency elects one member [4].

Limits

• No reservation in the upper houses. The Rajya Sabha and state Legislative Councils have none.
• These houses are elected indirectly: elected members choose them, not voters directly.

• 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].

• Not permanent: Art. 334 puts a time limit on it. Parliament must extend that limit by amendment.

• Only SCs and STs: there is no reservation on the grounds of religion.

In the Constitution and practice

• Colonial background: separate electorates
• Indian Councils Act, 1909 (Morley-Minto Reforms): separate electorates for Muslims.
• The Government of India Acts of 1919 and 1935 extended them to more communities.

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

• Poona Pact (1932): the model for today's system

• Gandhi and Ambedkar agreed on reserved seats in a joint electorate instead of separate electorates.

• Ambedkar's critique: the winner needs votes from other castes. So the winner may be the SC candidate the dominant castes accept, not the one SC voters prefer.

• Constituent Assembly

• Many members felt separate electorates had helped cause Partition. Tajamul Husain (26 May 1949) called them "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 amended text dropped seat reservation for Muslims and Christians and kept it only for SCs and STs. The Assembly adopted it on 24 August 1949 [6].

• The articles today

• Art. 325: no one can be left off the general roll, or put on a special roll, only because of religion, race, caste or sex. This rules out separate electorates.
• Art. 330 (Lok Sabha): reserves seats for (a) SCs; (b) STs, except those in the autonomous districts of Assam; (c) STs in the autonomous districts of Assam [6].
• Art. 330(3): seats for STs in Assam's autonomous districts must be at least in proportion to their share of the state's population [6].

• Art. 332: the same scheme for state Legislative Assemblies.

• Extensions under Art. 334 (the original limit was 10 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].
• It moved the limit from 25 January 2020 to 25 January 2030 [2].

• It did not extend Anglo-Indian nomination under Art. 331 (Lok Sabha) and Art. 333 (state assemblies) [2]. That nomination ended in January 2020.

• 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, and a Supreme Court judge would chair it [3].

• Women's reservation: the 106th Amendment, 2023 reserves one-third of seats for women. It starts only after the next delimitation.

Don't confuse with

• Separate electorate: only voters of one community vote for that community's seat (1909 to 1935 Acts). In a reserved constituency, all voters vote and only the candidate must be SC/ST.
• Anglo-Indian nomination (Arts. 331 and 333): members were nominated, not elected. It ended in January 2020, while SC/ST reservation runs to 2030.
• Rajya Sabha / Legislative Councils: these are elected indirectly and have no SC/ST reservation. Only the Lok Sabha and state assemblies have it.
• Placing ST seats vs. SC seats: ST seats go where the ST share is largest. SC seats go where the SC share is comparatively large but are spread across the state [4].

Prelims Hooks

• Art. 330 covers the Lok Sabha, Art. 332 covers state assemblies, and Art. 334 sets the time limit. Art. 325 requires a single general electoral roll.
• The 104th Amendment (2019), passed as the 126th Amendment Bill, extended SC/ST reservation to 25 January 2030 and ended Anglo-Indian nomination [2].
• 84 SC + 47 ST = 131 reserved seats out of 543 in the Lok Sabha.
• Trap: the Rajya Sabha and Legislative Councils have no SC/ST reservation [5].
• Communal Award (1932) offered separate electorates to the Depressed Classes. The Poona Pact (1932) replaced them with reserved seats in a joint electorate.
• Draft Art. 292 became Art. 330 and was adopted on 24 August 1949. The final text dropped reservation for Muslims and Christians [6].

Mains Points

• Joint electorate with reserved seats vs. separate electorates
• Reserved seats guarantee that SCs and STs are present in the legislatures without splitting voters by community. The Constituent Assembly chose this after Partition.

• The cost is Ambedkar's Poona Pact worry: winners need non-SC votes, so they may not be the true choice of SC voters.

• "Temporary" reservation, renewed seven times

• Art. 334 began with a 10-year limit but has been extended every decade, up to 2030.

• This shows that SCs and STs are still left out of politics. It also raises the question of what evidence should decide future extensions.

• Delimitation decides who benefits

• The rules for placing ST and SC seats, and rotation, decide which communities get representation. Rotation also makes it harder for members to build ties with one constituency.
• The Delimitation Bill 2026 [3] and the 106th Amendment make the next delimitation central to SC/ST and women's representation.
• Gaps remain: there are no reserved seats in the upper houses and none for Muslims. Possible answers within the Constitution include party-level candidate quotas or a debate on proportional representation (PR), rather than religious quotas.
