TNPSC social justice and reservation in Tamil Nadu: practice questions

By the PrepMatic team · Updated 9 Oct 2026 · 4 min read

Tamil Nadu's story of social justice appears in two places in the TNPSC syllabus: as history under the socio-political movements of Tamil Nadu, and as policy under development administration. Both sit in the two largest General Studies units, each worth about 20 of the 75 questions in the indicative split. The five questions below test the dates, the legal milestones and the percentages. For the broader subject, see the TNPSC Development Administration guide.

What this topic covers

• Origins: the Justice Party (South Indian Liberal Federation), founded in 1916, and the first Communal Government Order of 1921.
• Legal milestones: the Champakam Dorairajan case, the First Amendment (1951), the Indra Sawhney judgment (1992) and the Ninth Schedule protection for the 69 per cent quota.
• The present arrangement: how the 69 per cent is divided among communities.

The shares below are the community-wise reservation printed in the Group 4 2026 notification (Notification No. 11/2026, dated 6 October 2026).

These add up to 69 per cent. The remaining 31 per cent is open competition. Women have a separate 30 per cent horizontal share, and persons with benchmark disabilities have 4 per cent.

Sample questions

Question 1

The South Indian Liberal Federation, popularly called the Justice Party, was founded in:

• A. 1885
• B. 1916

• D. Tenth Schedule

Question 3

In the Indra Sawhney case (1992), the Supreme Court generally fixed the upper limit on total reservation at:

• A. 69 per cent
• B. 60 per cent
• C. 33 per cent
• D. 50 per cent

Question 4

The First Constitutional Amendment (1951), which added Article 15(4) for special provisions for backward classes, followed a case from:

• A. Madras
• B. Bombay
• C. Bengal
• D. Punjab

Question 5

In Tamil Nadu's community-wise reservation, the share of Most Backward Classes and Denotified Communities is:

• A. 15 per cent
• B. 20 per cent
• C. 26.5 per cent
• D. 3.5 per cent

Answers and explanations

1. B. The Justice Party was formed in 1916 by T. M. Nair, P. Theagaraya Chetty and others to represent non-Brahmin interests. It formed the first elected ministry in the Madras Presidency after the 1920 elections.
2. C. The 76th Amendment (1994) placed the Tamil Nadu reservation Act in the Ninth Schedule, which is meant to protect laws from challenge. Courts have since held that Ninth Schedule laws can be reviewed if they violate the basic structure.
3. D. Indra Sawhney set a general ceiling of 50 per cent. Tamil Nadu's 69 per cent exceeds it, which is why the state sought Ninth Schedule protection.
4. A. The case was State of Madras v. Champakam Dorairajan. The courts struck down a communal allocation in college admissions, and Parliament responded with the First Amendment, which added Article 15(4).
5. B. MBC and Denotified Communities hold 20 per cent. BC (other than Muslims) hold 26.5 per cent, BC Muslims hold 3.5 per cent and SC hold 15 per cent.

How to prepare social justice and reservation

Treat this topic as a timeline with five dated beats: 1916 (Justice Party), 1921 (Communal G.O.), 1951 (Champakam Dorairajan and the First Amendment), 1992 (Indra Sawhney) and 1993 to 1994 (the 69 per cent Act and its Ninth Schedule listing). Add the leaders for each beat in the margin, since questions often name a person and ask for the movement or the year.

For percentages, memorise the table above as a sum: 26.5 plus 3.5 plus 20 plus 15 plus 3 plus 1 equals 69. If you know the total, you can recover any one figure you forget. Do not mix up the community shares with the 30 per cent for women or the 4 per cent for persons with disabilities, because those are horizontal reservations that cut across communities.

Pair this page with TNPSC social reform movements practice and TNPSC Dravidian movement practice, where the same story is told through reformers. If you plan to apply, read the current notification for the reservation and eligibility rules that apply to your post, because this page explains the principles and not individual claims.
