Fundamental Rights: A Complete UPSC Guide with Landmark Case Laws 2026

Fundamental Rights: A Complete UPSC Guide with Landmark Case Laws 2026

Introduction

Part III of the Indian Constitution (Articles 12–35) is often called the

“Magna Carta of India.”

It guarantees Fundamental Rights (FRs) that are justiciable — meaning citizens can directly approach the Supreme Court (Article 32) or High Courts (Article 226) if these rights are violated. For UPSC Prelims and Mains (GS Paper II), this is one of the highest-yield topics, and questions frequently test the

interplay between Articles and case law

. This blog covers every FR article along with the landmark judgments that shaped its interpretation.

Article 12: Definition of “State”

Article 12 defines “State” to include the Government and Parliament of India, State governments and legislatures, and all local or other authorities within India or under the control of the Government of India.

Key Case:

Rajasthan Electricity Board v. Mohan Lal (1967)

– Held that “other authorities” includes bodies created under statute, even if not exercising sovereign functions.

Ajay Hasia v. Khalid Mujib (1981)

– Laid down the “instrumentality or agency of the State” test: if a body is financially, functionally, and administratively controlled by the government, it qualifies as “State” under Article 12.

Pradeep Kumar Biswas v. Indian Institute of Chemical Biology (2002)

– Refined the Ajay Hasia test, holding that deep and pervasive control by government is the real test, not just the source of funding.

Article 13: Laws Inconsistent with Fundamental Rights

Article 13 declares that any law inconsistent with FRs is void to the extent of such inconsistency. This gave rise to the

doctrine of judicial review

.

Key Case:

Shankari Prasad v. Union of India (1951)

– Held that Parliament’s power to amend the Constitution under Article 368 includes the power to amend Fundamental Rights, and a Constitutional Amendment is not “law” under Article 13.

Golaknath v. State of Punjab (1967)

– Reversed this position; held that Fundamental Rights are “transcendental” and Parliament

cannot

amend Part III. This led to the 24th Constitutional Amendment (1971), which restored Parliament’s amending power.

Article 14: Right to Equality

Guarantees “equality before law” and “equal protection of laws.” It permits

reasonable classification

but prohibits

class legislation

.Fundamental Rights:

Key Cases:

State of West Bengal v. Anwar Ali Sarkar (1952)

– Struck down a special courts law for lacking a rational basis for classification, establishing the twin test: intelligible differentia + rational nexus with the object.

E.P. Royappa v. State of Tamil Nadu (1974)

– Justice Bhagwati introduced the “new dimension” of Article 14: equality is antithetic to arbitrariness; arbitrariness in State action violates Article 14.

Maneka Gandhi v. Union of India (1978)

– Linked Article 14 with Article 21, holding that any procedure affecting life and liberty must be fair, just, and reasonable — not arbitrary.

Shayara Bano v. Union of India (2017)

– Struck down instant Triple Talaq as arbitrary and violative of Article 14.

Article 15: Prohibition of Discrimination

Prohibits discrimination on grounds of religion, race, caste, sex, or place of birth, while allowing affirmative action (special provisions) for women, children, SC/ST, and OBCs.

Key Cases:

State of Madras v. Champakam Dorairajan (1951)

– Struck down caste-based reservation in college admissions as violative of Article 15(1); led to the

First Constitutional Amendment

, inserting Article 15(4).

Indra Sawhney v. Union of India (1992)

(“Mandal Case”) – Upheld 27% OBC reservation, introduced the concept of “creamy layer” exclusion, and capped total reservation at 50% (with exceptions).

Navtej Singh Johar v. Union of India (2018)

– While primarily an Article 21 case, it also read “sex” in Article 15 to include sexual orientation, decriminalizing consensual homosexual acts by striking down parts of Section 377 IPC.

Article 16: Equality of Opportunity in Public Employment

Guarantees equality of opportunity in matters of public employment, subject to reservation provisions for backward classes.

Key Cases:

M. Nagaraj v. Union of India (2006)

– Upheld reservation in promotions (Article 16(4A)) but required the State to collect quantifiable data on backwardness, inadequacy of representation, and administrative efficiency before granting such reservation.

Jarnail Singh v. Lachhmi Narain Gupta (2018)

– Removed the requirement of collecting quantifiable data specifically on “backwardness” for SC/STs (since they are already recognized as backward), while retaining the need for adequate representation data.

Janhit Abhiyan v. Union of India (2022)

– Upheld the 103rd Amendment providing 10% EWS (Economically Weaker Sections) reservation, holding that economic criteria alone can be a valid basis for reservation and that this does not violate the basic structure.

Article 17: Abolition of Untouchability

Abolishes “untouchability” in any form and forbids its practice, made punishable under the Protection of Civil Rights Act, 1955.

Key Case:

State of Karnataka v. Appa Balu Ingale (1993)

– Supreme Court gave a wide interpretation to “untouchability,” covering all forms of social discrimination arising from caste-based practices.

Article 18: Abolition of Titles

Prohibits the State from conferring titles (except military/academic distinctions) and prohibits citizens from accepting titles from foreign states.

Key Case:

Balaji Raghavan v. Union of India (1996)

– Upheld the constitutional validity of National Awards (Bharat Ratna, Padma awards), holding they are not “titles” under Article 18 as long as they are not used as suffixes/prefixes.

Article 19: Right to Freedom (Six Freedoms)

– Struck down Section 66A of the IT Act, 2000, as unconstitutional for being vague and having a “chilling effect” on free speech.

Indibly Creative Pvt. Ltd. v. State of West Bengal (2019)

and

S. Rangarajan v. P. Jagjivan Ram (1989)

– Reinforced that freedom of speech cannot be curtailed merely due to threat of public disorder from hostile audiences (“heckler’s veto”).

Anuradha Bhasin v. Union of India (2020)

– Held that the right to access the internet is part of the freedom of speech and expression under Article 19(1)(a) and freedom to carry on trade/business under 19(1)(g).

Provides protection against ex-post-facto laws, double jeopardy, and self-incrimination.

Key Cases:

Kalawati v. State of Himachal Pradesh (1953)

– Clarified that protection against double jeopardy applies only when there has been a prior prosecution and punishment for the same offence.

– Held that involuntary administration of narco-analysis, polygraph, and BEAP tests violates Article 20(3) (protection against self-incrimination) and Article 21.

Article 21: Right to Life and Personal Liberty

Key Cases (the backbone of UPSC FR questions):

A.K. Gopalan v. State of Madras (1950)

Maneka Gandhi v. Union of India (1978)

Article 32: Right to Constitutional Remedies

, laying the foundation for

Public Interest Litigation (PIL)

– Further broadened PIL jurisdiction under Article 32, allowing even a letter to the Court to be treated as a writ petition.

UPSC Exam Tips

Prelims:

Focus on matching Articles with correct case names and the

year

of the judgment — a common statement-based question format.

Mains (GS-II):

Always link FRs with

Directive Principles of State Policy (DPSP)

— questions often ask about the “harmonious construction” between Part III and Part IV, especially using Minerva Mills.

Answer writing:

Structure your answer as

Constitutional Provision → Judicial Interpretation → Contemporary Relevance

to maximize value addition.

Current Affairs Link:

Track ongoing cases like the Sabarimala review (9-judge bench) and Uniform Civil Code debates, as these frequently connect to Articles 25, 26, and 44.

Conclusion

Fundamental Rights are not static text — they are a living framework shaped continuously by judicial interpretation. From the narrow reading in

A.K. Gopalan

to the transformative approach in

Maneka Gandhi

and

Puttaswamy

, the judiciary has progressively expanded the scope of Part III to meet the needs of a changing society. For UPSC aspirants, mastering the interplay between constitutional text and landmark case law is essential — not just for Prelims MCQs, but for writing nuanced, example-backed Mains answers.
