Articles 15 and 16 for CLAT: Reservation Explained

📑 On this page

⚡ The short answer

Article 15 bars the State from discriminating against citizens on grounds only of religion, race, caste, sex or place of birth; Article 16 guarantees equal opportunity in government jobs. Both allow special provisions for women, backward classes, SCs, STs and the economically weaker. Reservation is part of equality, within limits: the 50% rule, the creamy layer and data.

🎬 The 30-second story

The two-column merit list

“Two columns on the State law college list?”

📋

Meher

Meher checks results.

“A lower scorer got a reserved seat. Caste discrimination!”

📝

Aarav

Aarav missed by two marks.

“I'm reserved category and ranked 3rd. I'm in the open column.”

🏆

Zoya

Zoya finds her row.

“Municipal job ad: 'Only men born in this district.'”

🏢

Rohan

Rohan was born in Pune.

Tara's ruling: Aarav loses: a backward-class quota is a special provision the Constitution allows. Zoya is right: a reserved candidate selected on merit takes an open seat. Rohan wins: no public job can be closed only for sex or birthplace.

What do Articles 15 and 16 actually forbid?

Both are Article 14 zoomed in. Article 15 names five lines the State may never draw by themselves. Article 16 repeats the idea for government jobs and adds two more.

🧩 At a glance

The forbidden grounds

🛕Religion

No benefit or burden only for your faith.

🧬Race

No line drawn on racial origin.

🪔Caste

Can't exclude you, though it may mark backwardness.

⚧️Sex

Includes rules built on stereotypes about sex.

📍Place of birth

Where you were born, not where you live.

👪Descent

Jobs only: no post because of your parents.

🏠Residence

Jobs only: Parliament alone may require it.

The word only matters. A rule resting on a banned ground plus a genuine other reason escapes Article 15, though Article 14 may bite. But in Navtej Johar, Chandrachud J rejected 'sex-plus' excuses: judge a rule by its effect.

Who is bound, and who is protected?

Only citizens can claim these Articles; foreigners fall back on Article 14. They mostly bind the State, but one clause reaches private owners: no citizen can be kept out of shops, public restaurants, hotels and places of entertainment on these grounds. A private café refusing a customer for his caste breaks the Constitution.

📌 What CLAT actually expects

The passage states the ground and the exception. Ask: is it the State (or a shop or hotel)? Is the banned ground the only reason? Does a special-provision clause save it?

How is Article 16 different from Article 15?

⚔️ Side by side

Two Articles, two arenas

🚪Article 15

all State action: admissions, schemes, access

•Five forbidden grounds
•Special provisions: women, children, backward classes, SCs, STs, EWS

💼Article 16

only public employment

•Seven grounds: adds descent and residence
•Reserved posts; SC/ST promotion quotas; EWS

Test	Article 15	Article 16
Covers	Seats, schemes, public places	Jobs and offices under the State
Residence	Not a forbidden ground	Forbidden, unless Parliament legislates
Women's quotas	Expressly allowed	Allowed too: the women clause reaches jobs

Is it about a job under the State? Then Article 16 is your rule.

Residence trips people up. 'Born in Bihar' is place of birth; 'lived in Bihar ten years' is residence. Article 15 bans only the first, so in 1955 a State college could charge non-residents a capitation fee. For public jobs, a residence condition needs a law by Parliament.

Residence quotas still face Article 14. In Tanvi Behl (2025) the Court struck down residence-based reservation in postgraduate medical seats, where merit must decide.

Why is reservation not a violation of equality?

Treating unequal people identically freezes inequality: a runner starting 200 metres behind doesn't get a fair race from a shared finish line. So the Constitution aims at substantive equality.

In 1951, Champakam Dorairajan struck down caste-wise medical seats, because Article 15 then had no backward-class clause; Parliament added one within months. Since Indra Sawhney, job reservation is read as part of equal opportunity, not an exception.

What limits did the courts put on reservation?

The 50% ceiling

Balaji (1962) struck down a 68% college quota. Indra Sawhney settled the rule: backward-class reservation should not exceed half, counted year by year. Only an extraordinary situation, like a remote population cut off from the mainstream, justifies crossing it.

Item	Counts toward 50%?	Why
SC, ST and OBC quotas	Yes	That's what the ceiling is for
Reserved candidates selected on merit	No	They take open seats
Carried-forward reserved posts	No	A separate class of vacancies
EWS quota (up to 10%)	No	Ceiling covers only backward-class quotas
Horizontal quotas: women, disabled	No	Adjusted within the slices

The creamy layer

If a backward class's best-off families scoop up every seat, its truly backward members stay behind. So Indra Sawhney held that the creamy layer, members who have moved well ahead, must be excluded from OBC quotas.

ℹ️ Still debated: a creamy layer for SCs and STs?

Jarnail Singh (2018) applied it to SC/ST promotions. In 2024, four of seven judges in Davinder Singh urged it for all SC/ST quotas, but that wasn't the question referred, so it isn't binding yet.

Vertical and horizontal quotas

⚔️ Side by side

Slices vs stripes

📊Vertical

quotas for social groups: SC, ST, OBC, EWS

•Each is its own slice of seats

↔️Horizontal

quotas that cut across: women, persons with disabilities

•Filled inside each vertical slice

Test	Vertical	Horizontal
Example	15% for SCs	3% for disabled candidates
Adds to the total?	Yes	No, it's adjusted within

A disabled SC candidate picked in the disability quota sits in the SC slice.

Remember Zoya: a reserved candidate on the open merit list counts as open. A quota is a floor, not a ceiling.

Can the State reserve for the poor alone?

In 1992, no: backwardness meant social backwardness, so a 10% quota for poorer 'forward' citizens fell. Parliament then amended the Constitution to allow up to 10% for economically weaker sections, excluding SCs, STs and OBCs.

A quota within a quota

Some castes on the SC list have moved ahead; others haven't. Davinder Singh lets a State prefer the least represented within the SC quota, if data backs it and no sub-group gets all the seats.

Women and children

This clause covers jobs too, so posts may be reserved for women. But it exists to advance women; 'protecting' them out of a job on stereotypes is discrimination.

Which reservation cases should you know?

⚖️

Landmark case · 1992 · Supreme Court (nine judges)

Indra Sawhney v Union of India

📋

What happened

On the Mandal Commission report, the Union reserved 27% of central vacancies for backward classes, plus 10% for poorer sections outside any quota.

❓

The question

Can caste mark a backward class, and how far can quotas go?

🔨

What the court held

27% upheld, minus the creamy layer. Caste can be a social class. Quotas shouldn't cross 50% save in extraordinary cases, nor reach promotions. The purely economic 10% fell.

What CLAT takes from it: Backwardness is social, the advanced are out, half is the line.

💰

Landmark case · 2022 · Supreme Court (five judges)

Janhit Abhiyan v Union of India

📋

What happened

A 2019 amendment allowed up to 10% reservation for economically weaker sections, excluding SCs, STs and OBCs.

❓

The question

Does excluding backward classes and crossing 50% damage the basic structure?

🔨

What the court held

Upheld 3:2. Economic criteria are valid; the exclusion is a fair balance; the 50% ceiling isn't rigid and binds only backward-class quotas. The dissent called the exclusion discriminatory.

What CLAT takes from it: The 50% rule binds backward-class quotas, not every quota.

🧩

Landmark case · 2024 · Supreme Court (seven judges)

State of Punjab v Davinder Singh

📋

What happened

Punjab offered half its SC job quota first to Balmikis and Mazhabi Sikhs. Chinnaiah (2005) had treated SCs as one indivisible class.

❓

The question

Can a State sub-classify SCs to help the least represented?

🔨

What the court held

Yes, 6:1, overruling Chinnaiah. Sub-classification is valid on data about inadequate representation, but no sub-group may get every SC seat. Trivedi J dissented.

What CLAT takes from it: Unequals within a beneficiary class may be treated differently.

How has CLAT tested this?

No past CLAT passage was built on Articles 15 and 16 themselves. One real question sits next door, on special provisions for women; two CLAT-style practice questions follow.

📝 Asked in CLAT 2018 · Q190 Overlap: special provisions for women

Statement: It is a fundamental duty, which is unenforceable in a Court of Law that every citizen shall renounce practices derogatory to the dignity of women.

Examine the Statement and Conclusions given below and choose a suitable answer. Conclusions: 1. Reservation of seats for women in employment is violative of the principle stated. 2. Asking a lady inappropriate questions about her personal life is violative of the principle stated.

AOnly Conclusion 1 follows.

BOnly Conclusion 2 follows.

CConclusions 1 and 2 follow.

DNeither Conclusion 1 nor 2 follows.

Reveal answer + reasoning

Answer: B

The principle targets practices that demean women. Reserving jobs for women advances them and is expressly permitted. Intrusive personal questions do demean, so only Conclusion 2 follows.

Why the others fail

A — Reservation for women isn't derogatory.
C — Conclusion 1 fails.
D — Conclusion 2 plainly fits.

🧪 CLAT-style practice (not a past question) CLAT-style: merit and the creamy layer

Reservations for backward classes shall not, save in extraordinary situations, exceed fifty per cent of the appointments in any year. Backward-class candidates selected on their own merit are treated as open-category candidates. Members of a backward class who have advanced socially and economically, the 'creamy layer', are excluded from the benefit of reservation.

A State advertises 100 posts: 27 OBC, 15 SC, 7 ST and 51 open. Zoya, an OBC candidate whose parents are senior civil servants, ranks 4th on the open merit list. Which is correct?

AShe must be adjusted against the OBC quota.

BShe gets an open post; her creamy-layer status is irrelevant.

CShe can't be appointed, being creamy layer.

DThe scheme is invalid for exceeding fifty per cent.

Reveal answer + reasoning

Answer: B

The creamy-layer rule removes Zoya only from the reserved benefit. She ranked 4th on merit, so she takes an open post. And 27 + 15 + 7 = 49%.

Why the others fail

A — Merit candidates aren't counted against the quota.
C — Exclusion is only from the quota.
D — 49% is within the limit.

🧪 CLAT-style practice (not a past question) CLAT-style: sub-classification

The State may sub-classify a beneficiary class and give preference to its least represented groups, provided the preference rests on empirical data showing inadequate representation. Sub-classification cannot be used to give one sub-group all the seats reserved for the class.

Without any survey, State X gives Caste P first claim on half the SC quota because a minister calls P 'the most deprived'. Caste Q challenges it. Which is correct?

AValid, as States may now sub-classify SCs.

BInvalid, as no data backs the preference.

CInvalid, as SCs can never be sub-classified.

DValid, as P gets half, not all, of the seats.

Reveal answer + reasoning

Answer: B

Sub-classification is allowed, but only on data. A minister's say-so is not a survey, so the preference fails the passage's first condition.

Why the others fail

A — Permission comes with a condition.
C — The passage allows it.
D — Meets only the second condition.

Frequently asked questions

What is the difference between Article 15 and Article 16?

Article 15 covers all State action, like admissions and schemes, and bans discrimination only on religion, race, caste, sex or place of birth. Article 16 covers government jobs and adds descent and residence. Both allow special provisions such as reservation.

Is reservation against the right to equality?

No. In Indra Sawhney the Supreme Court held that job reservation is a facet of equal opportunity, not an exception. Treating unequal groups identically freezes old disadvantage, so the State may help socially backward, under-represented groups, within limits.

What is the creamy layer?

Members of a backward class who have moved well ahead socially and economically, through high income or senior posts. They must be excluded from OBC reservation so the benefit reaches the truly backward. Whether this extends to all SC and ST quotas is debated.

Can reservation ever cross 50%?

Only in extraordinary situations, such as a remote population far from the mainstream, with a special case made out; the Maratha quota fell in 2021 for lacking one. The ceiling covers backward-class quotas only, so EWS sits outside it.

What did the Supreme Court decide on the EWS quota?

In Janhit Abhiyan (2022) a five-judge bench upheld the 10% EWS quota by 3:2. The majority held economic criteria valid and the exclusion of SCs, STs and OBCs, who have their own quotas, permissible. The dissent found that exclusion discriminatory.
