Fundamental Rights & Landmark Judgements: The 30-Second Answer

Fundamental Rights Landmark Judgements: UPSC Revision Notes Simplified

Fundamental Rights (Articles 12–35) are justiciable rights guaranteed by Part III of the Constitution, and their scope has been progressively widened by the judiciary — from the strict, textual reading of A.K. Gopalan (1950) to the expansive, substantive due process approach of K.S. Puttaswamy (2017). For UPSC, the story of Fundamental Rights is the story of these landmark judgements: each case added a doctrinal layer — classification, arbitrariness, due process, proportionality — turning Part III into a living charter.

Quick Recap: The Six Fundamental Rights (Articles 12–35)

RightsArticlesOne-line essence
Right to Equality14–18Equality before law, non-discrimination, equal opportunity, abolition of untouchability and titles
Right to Freedom19–22Six freedoms (Art. 19), protection in criminal convictions (Art. 20), life & liberty (Art. 21), safeguards on arrest (Art. 22)
Right against Exploitation23–24Prohibits human trafficking, forced labour, and child labour in hazardous employment
Right to Freedom of Religion25–28Freedom of conscience, practice, propagation; secular character of state institutions
Cultural & Educational Rights29–30Protection of minority language, script, culture; right to establish educational institutions
Right to Constitutional Remedies32Enforcement of FRs through writs — Ambedkar: “the heart and soul of the Constitution”

Article 12 & 13: ‘State’ and Judicial Review Basics

Article 12 defines ‘State’ to include the Government and Parliament of India, state legislatures, and all local or other authorities. In Raj Narain v. State of UP and later R.D. Shetty v. International Airport Authority, courts read “other authorities” expansively — instrumentality or agency of government tests brought public sector undertakings and statutorily-created bodies within Article 12, making them amenable to Fundamental Rights challenges.

Article 13 is the engine of judicial review: pre- and post-Constitution laws inconsistent with FRs are void to the extent of inconsistency. Crucially, the Supreme Court in Kesavananda Bharati and later cases affirmed that a constitutional amendment can also be tested against Part III (subject to the basic structure doctrine), making Article 13 the gateway through which every doctrinal evolution in this article flows.

Article 14: Reasonable Classification to the Maneka Gandhi Leap

  • State of West Bengal v. Anwar Ali Sarkar (1952): codified the reasonable classification doctrine — classification must rest on intelligible differentia with a rational nexus to the object.
  • E.P. Royappa v. State of Tamil Nadu (1974): introduced the arbitrariness doctrine — “equality is antithetic to arbitrariness,” collapsing the twin-test formalism.
  • Maneka Gandhi v. Union of India (1978): linked Articles 14, 19 and 21 into the Golden Triangle; any procedure depriving life or liberty must be fair, just and reasonable — importing substantive due process into Article 14.

Article 19: Free Speech — From Gopalan to Shreya Singhal

Article 19(1) guarantees six freedoms — speech and expression, assembly, association, movement, residence, and profession — subject to the reasonable restrictions of Article 19(2) (sovereignty and integrity of India, security of the State, public order, decency, morality, contempt, defamation, incitement).

In Shreya Singhal v. Union of India (2015), the Supreme Court struck down Section 66A of the Information Technology Act, 2000, as vague and overbroad, holding that “discussion and advocacy” are protected while only “incitement” in relation to the eight subjects of Article 19(2) may be restricted. It also mandated intermediary due process — notice and hearing before content takedowns. In Anuradha Bhasin v. Union of India (2020), the Court held internet access restrictions on speech are subject to the proportionality test, with shutdown orders requiring publication and review.

Article 21: The Golden Triangle and Due Process Evolution

  1. A.K. Gopalan v. State of Madras (1950): Articles 19, 21 and 22 read as mutually exclusive; “procedure established by law” meant any enacted procedure, however unfair — a purely textualist view.
  2. Maneka Gandhi (1978): overruled Gopalan’s silo approach; procedure must be “right, just and fair” — the effective judicial incorporation of due process.
  3. K.S. Puttaswamy v. Union of India (2017): a 9-judge bench unanimously held privacy is a Fundamental Right intrinsic to Article 21 and Part III, protected by a three-fold test: legality, legitimate state aim, and proportionality.
  4. Common Cause v. Union of India (2018): recognised the right to die with dignity (passive euthanasia, living wills).
  5. Navtej Singh Johar v. Union of India (2018): decriminalised consensual same-sex relations by reading down Section 377 IPC, invoking transformative constitutionalism.

Articles 23–24 & 25–28: Exploitation, Religion and Essential Religious Practices

Shayara Bano v. Union of India (2017): instant triple talaq (talaq-e-biddat) was held unconstitutional as arbitrary and manifestly unconstitutional — a striking application of arbitrariness review to personal law practice, later given statutory force by the Muslim Women (Protection of Rights on Marriage) Act, 2019.

Sir Dinshah Muncheshah contract… Shirur Mutt (1954) laid down the essential religious practices test: only those practices essential and integral to a religion get Article 25 protection; secular activities of religious bodies are regulable. Sabarimala (Indian Young Lawyers Association v. Kerala, 2018) applied the test alongside Articles 14 and 25 to allow women’s entry, while Bijoe Emmanuel v. State of Kerala (1986) (“National Anthem case”) held that no person can be compelled to act against genuine religious belief where no public order interest is harmed.

Articles 29–30 & 32–35: Minority Rights and the ‘Heart and Soul’ of the Constitution

St. Stephen’s College v. University of Delhi (1992) and TMA Pai Foundation v. State of Karnataka (2002) clarified Article 30: minorities (religion- or language-based, determined at the state level per Pai) have the right to establish and administer educational institutions, subject to regulation for educational standards and, per Pai, a reasonable reservation obligation for weaker sections.

Article 32 — Dr. Ambedkar called it “the very soul of the Constitution and the very heart of it” — because it converts Fundamental Rights from declarations into enforceable guarantees, empowering the Supreme Court to issue writs (habeas corpus, mandamus, prohibition, certiorari, quo warranto). Kesavananda Bharati v. State of Kerala (1973) held Parliament cannot amend away the Constitution’s basic structure, permanently insulating the FR framework. Article 32 is itself a Fundamental Right; Article 226 gives High Courts wider but discretionary writ powers. Articles 33–35 permit Parliament to restrict FRs for armed forces and to legislate on enforcement.

The Evolving Tests: A.K. Gopalan → Maneka → Puttaswamy (Visual Timeline)

Maneka Gandhi (1978)Golden Triangle; substantive due processFair, just and reasonable procedure
Shreya Singhal (2015)Speech protection onlineVagueness + overbreadth; incitement standard

Mains-Ready Keywords & Case-Quote Bank

  • Due process of law — fairness of substance and procedure (Maneka Gandhi’s substantive due process import).
  • Procedure established by law — Article 21’s literal text; originally any validly enacted procedure (Gopalan).
  • Proportionality — state action must be suitable, necessary, and balanced against the right (Puttaswamy, Anuradha Bhasin).
  • Basic structure doctrine — amendability limited (Kesavananda Bharati).
  • Reasonable restriction — Article 19(2) limits must be proportionate, not arbitrary.
  • Horizontal application — debate on FRs against private actors (relevant post-Puttaswamy discourse).
  • Transformative constitutionalism — Navtej Johar; Constitution as a charter of social transformation.

Frequently Asked Questions

What are the six Fundamental Rights in the Indian Constitution?

Right to Equality (Arts. 14–18); Right to Freedom (Arts. 19–22); Right against Exploitation (Arts. 23–24); Right to Freedom of Religion (Arts. 25–28); Cultural and Educational Rights (Arts. 29–30); and Right to Constitutional Remedies (Art. 32). The Right to Property, once Art. 31, was deleted from Part III by the 44th Amendment (1978).

Which case introduced due process of law in India?

Maneka Gandhi v. Union of India (1978) — the Court held that any procedure under Article 21 must be fair, just and reasonable, effectively judicially incorporating due process without amending the constitutional text.

Is Right to Privacy a Fundamental Right?

Yes. In K.S. Puttaswamy v. Union of India (2017), a nine-judge bench unanimously held privacy is part of Article 21 and Part III, subject to the legality–legitimate aim–proportionality test.

Can Fundamental Rights be amended?

Yes, by constitutional amendment under Article 368 (per the 24th Amendment), but not in a manner that violates the basic structure, as held in Kesavananda Bharati (1973).

What is the difference between Article 32 and Article 226?

Article 32 is itself a Fundamental Right, enforceable in the Supreme Court for FR violations. Article 226 gives High Courts wider writ powers (FRs plus legal rights), but relief there is discretionary.
