What Article 15 says
Article 15 prohibits the State from discriminating against any citizen on grounds only of religion, race, caste, sex or place of birth. Five grounds. Not descent, not residence, not language, not disability, and that omission is where half the prelims questions live. It is available only to citizens, unlike Article 14 which protects all persons including foreigners and companies.
The Article as originally drafted had three clauses. Three more were added by amendment, in 1951, 2005 and 2019, each one a response to a court judgment or a political demand. Here is the full structure.
| Clause | What it does | Source |
|---|---|---|
| 15(1) | Bars the State from discriminating against a citizen on grounds only of religion, race, caste, sex or place of birth | Original |
| 15(2) | Bars discrimination on the same grounds in access to shops, restaurants, hotels, places of public entertainment, and use of wells, tanks, bathing ghats, roads and places of public resort maintained out of State funds or dedicated to the public. Binds private persons too | Original |
| 15(3) | Allows the State to make special provisions for women and children | Original |
| 15(4) | Allows special provisions for socially and educationally backward classes, SCs and STs | 1st Amendment, 1951 |
| 15(5) | Allows reservation in admissions to educational institutions, including private aided and unaided ones, except minority institutions under Article 30(1) | 93rd Amendment, 2005 |
| 15(6) | Allows special provisions and up to 10 percent reservation for economically weaker sections not already covered by 15(4) and 15(5) | 103rd Amendment, 2019 |
The word "only" does most of the work
Read 15(1) again. It says on grounds only of religion, race, caste, sex or place of birth. That single word is why the State can discriminate on a mix of grounds, or on grounds not in the list, and still survive Article 15.
A rule that says women get free bus travel is not struck down, because 15(3) rescues it. A rule that reserves seats in a state medical college for candidates domiciled in that state is a residence classification, not a place of birth classification, and place of birth means where you were born, not where you live. Aspirants collapse these two constantly. Domicile-based admission quotas are tested under Article 14 and 15 has almost nothing to say about them.
Clause 2 is the sleeper. Most Fundamental Rights operate against the State. Article 15(2) operates horizontally, against private individuals as well, which is why a private restaurant refusing entry on caste grounds is directly unconstitutional and not merely illegal under some statute. Article 17 and Article 23 share this quality. Remember the set of three.
The three amendments, and why each happened
Clause 4 came out of a defeat. In State of Madras v. Champakam Dorairajan (1951), the Supreme Court struck down a communal government order allotting medical and engineering seats by community, because Article 15 as it then stood had no enabling provision for caste-based reservation. Parliament responded within months with the First Constitutional Amendment, inserting 15(4). That amendment also created Article 31A and the Ninth Schedule, so it is a high-value amendment overall.
Clause 5 came out of P.A. Inamdar (2005), where the Court held that the State cannot impose reservation on private unaided institutions. Parliament inserted 15(5) the same year through the 93rd Amendment. Ashoka Kumar Thakur (2008) upheld it for state and aided institutions and imported the creamy layer exclusion for OBCs, and Pramati Educational Trust (2014) upheld it for private unaided institutions while confirming that minority institutions stay outside it.
Clause 6 is the newest. The 103rd Amendment of 2019 added 15(6) and 16(6), creating up to 10 percent reservation for economically weaker sections outside the SC, ST and OBC categories. Janhit Abhiyan v. Union of India, decided in November 2022 by a 3:2 majority, upheld it and held that reservation purely on economic criteria does not violate the basic structure, and that breaching the fifty percent ceiling for EWS does not either. The two dissenting judges objected mainly to the exclusion of SC, ST and OBC candidates from the EWS pool. Know the split. That is exactly the level of detail a well-set prelims question probes.
Article 14 vs 15 vs 16, the confusion that costs marks
Aspirants read these three in one sitting and merge them in memory. Separate them by scope, by who can claim them, and by the list of grounds.
- Article 14 covers all persons, including foreigners and companies. Articles 15 and 16 cover citizens only.
- Article 15 lists five grounds. Article 16(2) lists seven, adding descent and residence to the same five.
- Article 15 operates in the general field of State action plus, through 15(2), certain private spaces. Article 16 is confined to public employment.
- Reservation in educational institutions flows from 15(4), 15(5) and 15(6). Reservation in jobs flows from 16(4), 16(4A), 16(4B) and 16(6).
- Promotion reservation with consequential seniority sits in 16(4A), added by the 77th and 85th Amendments. Article 15 has no promotion clause at all.
How this is actually tested, and what to do about it
UPSC does not ask you to recite Article 15. It asks which article permits special provision for women, or whether reservation in private unaided institutions is constitutionally backed, or whether a given right is available to non-citizens. The question is always one layer removed from the bare text.
So build the article as a small map, not a paragraph. Clause number, what it allows, which amendment brought it, which case triggered that amendment. Four columns in your notebook. When you revise, cover the middle two and rebuild them from the clause number. Ten minutes, and it holds for months.
Then do the thing most people skip. Go pull every prelims question from the last fifteen years on Fundamental Rights and sort them by which article they were really testing. You will notice something uncomfortable: the questions repeat their logic even when they change their wording, and the same three or four traps come back. Domicile versus place of birth. Citizens versus persons. Which rights bind private parties. If you want that sorting done systematically instead of on a rainy Sunday, the PYQ Mastery Course works through past papers by pattern rather than by year, which is the only way this particular blind spot gets fixed.
One last thing worth carrying. Article 15 is not a reservation provision that grew accidental exceptions. It is an equality provision, and clauses 4, 5 and 6 exist because formal equality alone kept producing unequal results. Answer writing in Mains rewards that framing far more than a clause list does.
FAQs
1. Is Article 15 available to foreigners?
No. Article 15 protects citizens only. Article 14, which guarantees equality before the law and equal protection of the laws, is the one available to all persons including foreigners and juristic persons like companies.
2. Which amendment added Article 15(6) for EWS reservation?
The 103rd Constitutional Amendment Act, 2019, inserted Article 15(6) and Article 16(6), allowing up to 10 percent reservation for economically weaker sections. The Supreme Court upheld it in Janhit Abhiyan v. Union of India in November 2022 by a 3:2 majority.
3. Can Article 15 be enforced against private individuals?
Only through clause 2. Article 15(2) bars discrimination by anyone, including private persons, in access to shops, restaurants, hotels, places of public entertainment, and public wells, tanks, roads and bathing ghats. The rest of Article 15 binds the State.
4. Are minority educational institutions covered by Article 15(5)?
No. Article 15(5) expressly excludes minority educational institutions referred to in Article 30(1), so reservation in admissions cannot be imposed on them. The Supreme Court confirmed this position in Pramati Educational Trust (2014).
5. What is the difference between Article 15 and Article 16 grounds?
Article 15 lists five grounds: religion, race, caste, sex and place of birth. Article 16(2) lists the same five plus descent and residence, making seven, and applies specifically to matters of public employment.
6. Does a state quota for local students violate Article 15?
Generally no, because such quotas are based on residence or domicile, and residence is not a prohibited ground under Article 15. These provisions are usually tested for reasonableness under Article 14 instead.
