A Consolidated, Cross-Referenced Digest of the Constitutional Cases Most Frequently Tested in UPSC
How to Use This Chapter
Earlier chapters introduced landmark cases in the context of the specific topic they relate to (Fundamental Rights, Judiciary, Emergency, etc.). This chapter consolidates them into a single chronological reference, adds cases not otherwise covered, and gives each a fuller treatment: facts, holding, and significance. Use this as a revision spine — if you can recall the one-line "significance" of every case below, you can handle the vast majority of case-based Prelims questions and cite them confidently in Mains answers.
Pre-Kesavananda Era (1950s–1973): The Formative Disputes
A.K. Gopalan v. State of Madras (1950)
Facts: Gopalan, detained under the Preventive Detention Act, challenged his detention as violating Articles 19, 21, and 22. Holding: The Supreme Court held that Articles 14, 19, and 21 are mutually exclusive — each must be tested independently against a challenged law; "procedure established by law" (Art. 21) merely requires that some valid procedure exists, not that it be fair or reasonable. Significance: Represents the earliest, most executive-deferential phase of Indian constitutional interpretation — later completely overturned by Maneka Gandhi (1978).
Shankari Prasad v. Union of India (1951)
Facts: Challenged the First Amendment (which added Articles 31A and 31B, protecting land reform laws from Fundamental Rights challenges) as violating Article 13(2) ("the State shall not make any law" abridging Fundamental Rights). Holding: A constitutional amendment under Article 368 is not "law" within the meaning of Article 13(2); therefore, Parliament CAN amend Fundamental Rights. Significance: First major statement on the amendability of Fundamental Rights — later reversed by Golaknath (1967), then partially restored (with the basic structure caveat) by Kesavananda Bharati (1973).
State of Madras v. Champakam Dorairajan (1951)
Facts: Challenged a Madras government order reserving seats in medical/engineering colleges based on caste/religion as violating Article 29(2) (no discrimination in state-aided educational institutions). Holding: DPSP (Art. 46, promoting educational interests of weaker sections) cannot override a Fundamental Right; Fundamental Rights prevail over DPSP in case of conflict. Significance: Directly prompted the First Constitutional Amendment, 1951, which inserted Article 15(4), allowing special provisions for socially/educationally backward classes — illustrating the immediate, direct feedback loop between judicial rulings and constitutional amendments in India's early years.
Berubari Union case (1960) — Presidential Reference under Article 143
Facts: Presidential reference on whether a legislative act (implementing the India-Pakistan agreement to cede Berubari Union territory) required a constitutional amendment. Holding: (i) Cession of Indian territory requires a constitutional amendment (Article 3 alone is insufficient for cession to a foreign country, only for internal reorganization); (ii) the Preamble is NOT part of the Constitution. Significance: The Preamble holding was later overruled by Kesavananda Bharati (1973). This case is a good example of the Supreme Court's advisory jurisdiction (Article 143) in action.
Golaknath v. State of Punjab (1967)
Facts: Challenged Punjab land reform legislation (protected under the Ninth Schedule) as violating Fundamental Rights. Holding: (Reversing Shankari Prasad) — a constitutional amendment IS "law" under Article 13(2); therefore, Parliament CANNOT amend/abridge Fundamental Rights at all. The Court applied the doctrine of "prospective overruling" — the judgment would not invalidate amendments already made, only apply going forward. Significance: The most rights-protective (and most restrictive-on-Parliament) phase of judicial interpretation — directly prompted Parliament to enact the 24th Amendment, 1971, explicitly affirming Parliament's power to amend any part of the Constitution including Fundamental Rights, and making Presidential assent to amendment bills mandatory.
The Basic Structure Era (1973 onward)
Kesavananda Bharati v. State of Kerala (1973)
Facts: The Swami of a religious mutt in Kerala challenged land reform legislation affecting mutt property; the case became a vehicle for the Supreme Court (sitting in an unprecedented 13-judge bench, the largest ever) to resolve the Golaknath-versus-24th Amendment conflict. Holding (by a wafer-thin 7-6 majority): Parliament has wide power to amend any part of the Constitution, including Fundamental Rights, under Article 368 — BUT this power does NOT extend to altering or destroying the Constitution's "basic structure" or "basic features." The judgment did not provide an exhaustive list of basic-structure elements, leaving this to be elaborated case-by-case. Significance: The single most important case in Indian constitutional law — establishes the permanent ceiling on Parliament's amending power. Also overruled the Berubari holding that the Preamble is not part of the Constitution (holding it IS part of the Constitution, though non-justiciable). Elements later identified as part of the "basic structure" (illustrative, non-exhaustive, built up across later cases): supremacy of the Constitution; republican and democratic form of government; secular character; separation of powers; federal character; unity and integrity of the nation; judicial review; free and fair elections; independence of the judiciary; parliamentary system of government; rule of law; harmony between Fundamental Rights and DPSP.
Indira Nehru Gandhi v. Raj Narain (1975)
Facts: Raj Narain challenged Indira Gandhi's election; Parliament, via the 39th Amendment, attempted to place the Prime Minister's election beyond judicial scrutiny (inserting Article 329A). Holding: The Supreme Court struck down this provision as violating the basic structure — specifically the principles of free and fair elections and judicial review. Significance: An early and dramatic demonstration of the Basic Structure Doctrine actually being applied to strike down a constitutional amendment (as opposed to Kesavananda merely establishing the doctrine in the abstract).
Maneka Gandhi v. Union of India (1978)
Facts: Maneka Gandhi's passport was impounded without being given reasons or a hearing; she challenged this under Articles 14, 19, and 21. Holding: (Overruling A.K. Gopalan's "mutually exclusive" approach) Articles 14, 19, and 21 are interconnected, forming a "golden triangle." "Procedure established by law" under Article 21 must be fair, just, and reasonable — not arbitrary. Any law depriving personal liberty must pass the tests of all three articles. Significance: Transformed Article 21 from a narrow procedural safeguard into an expansive substantive due process-like protection — the foundation for later judicial expansion of Article 21 into rights to privacy, livelihood, clean environment, speedy trial, legal aid, etc.
Minerva Mills v. Union of India (1980)
Facts: Challenged provisions of the 42nd Amendment, 1976, which had (i) given DPSP overriding primacy over Fundamental Rights (Articles 14 and 19) when implementing Article 39(b)/(c), and (ii) attempted to place constitutional amendments beyond judicial review. Holding: Struck down both provisions as violating the basic structure. Held that harmony and balance between Fundamental Rights and DPSP is itself part of the basic structure — neither can be given absolute primacy over the other. Also reaffirmed that judicial review is part of the basic structure, and Parliament cannot exclude constitutional amendments from it. Significance: A crucial corrective to the 42nd Amendment's overreach, restoring the FR-DPSP balance and judicial review.
S.R. Bommai v. Union of India (1994)
Facts: Arose from multiple instances of alleged misuse of Article 356 (President's Rule) to dismiss state governments for political reasons. Holding: (i) The imposition of President's Rule is subject to judicial review; (ii) the President's "satisfaction" is not immune from scrutiny if based on mala fide or irrelevant grounds; (iii) the floor of the Legislative Assembly (a formal vote of confidence), not the Governor's subjective assessment, is the proper test of whether a government has lost majority support; (iv) secularism is part of the basic structure — a state government can be dismissed for engaging in anti-secular activities. Significance: Dramatically curbed the arbitrary, politically-motivated use of Article 356, which had been invoked over 100 times before this judgment (invocations dropped sharply afterward).
Federalism, Reservation, and Governance Cases
State of West Bengal v. Union of India (1963)
Facts: West Bengal challenged the Centre's power to acquire state property for a coal-mining project under the Coal Bearing Areas (Acquisition and Development) Act, 1957. Holding: India is not a "true" federation in the classical (American) sense — described as an "indestructible Union of destructible states" — Parliament can alter state boundaries/existence under Articles 3-4 without requiring state consent, and the Centre retains significant residual authority. Significance: Foundational case for characterizing Indian federalism as "quasi-federal" or asymmetric, with a strong unitary bias.
Indra Sawhney v. Union of India (1992) — "Mandal Commission case"
Facts: Challenged the Union government's decision to implement 27% OBC reservation in central government jobs, based on the Mandal Commission's recommendations. Holding: Upheld OBC reservation in public employment (not in promotions, at that stage); capped total reservations at 50% (except in extraordinary circumstances); introduced the "creamy layer" concept — excluding the socially/economically advanced sections within OBCs from reservation benefits; held that reservation should be limited to initial appointment, not extend automatically to promotions (later modified by subsequent amendments — Articles 16(4A), 16(4B)). Significance: The foundational case on the modern reservation framework, still the reference point for the 50% ceiling debate (subsequently complicated by the 103rd Amendment's separate EWS quota).
M. Nagaraj v. Union of India (2006)
Facts: Challenged the constitutional validity of Articles 16(4A) and 16(4B) (reservation in promotion for SC/ST). Holding: Upheld the provisions as constitutionally valid, but held that the state must collect quantifiable data showing backwardness, inadequacy of representation, and impact on administrative efficiency before providing reservation in promotions — the "creamy layer" principle applies to SC/ST promotion-reservation too (a holding later partially revisited in Jarnail Singh, 2018).
Jarnail Singh v. Lachhmi Narain Gupta (2018)
Holding: Held that SC/STs do not need to prove "backwardness" separately (they are presumed backward due to historical discrimination) for promotion reservation, but the "creamy layer" exclusion principle (from M. Nagaraj) still applies even to SC/ST reservation in promotions.
Personal Liberty and Article 21 Expansion Cases (Post-Maneka Gandhi)
Justice K.S. Puttaswamy v. Union of India (2017) — "Right to Privacy case"
Facts: Arose in the context of challenges to the Aadhaar scheme's mandatory linkage requirements. Holding: A 9-judge bench unanimously declared the Right to Privacy a Fundamental Right, protected under Article 21 (and as part of the freedoms guaranteed by Part III more broadly). Significance: One of the most consequential recent expansions of Article 21; directly enabled the subsequent Navtej Singh Johar and Joseph Shine judgments.
Navtej Singh Johar v. Union of India (2018)
Holding: Read down Section 377 of the IPC, decriminalizing consensual homosexual acts between adults, as violating Articles 14, 15, 19, and 21 (dignity, privacy, and equality).
Joseph Shine v. Union of India (2018)
Holding: Struck down Section 497 of the IPC (adultery as a criminal offence), as violating Articles 14 and 21 — held the provision was based on outdated notions of women as property of their husbands.
Shayara Bano v. Union of India (2017) — "Triple Talaq case"
Holding: A 3-2 majority declared the practice of "instant" (talaq-e-biddat) Triple Talaq unconstitutional, as arbitrary and violative of Article 14. Subsequently, Parliament enacted the Muslim Women (Protection of Rights on Marriage) Act, 2019, criminalizing the practice.
Judicial Appointments Cases (The "Judges Cases")
S.P. Gupta v. Union of India (1981) — "First Judges Case"
Holding: "Consultation" under Article 124(2)/217(1) does not mean "concurrence" — gives primacy to the executive's view in judicial appointments/transfers over the judiciary's.
Supreme Court Advocates-on-Record Association v. Union of India (1993) — "Second Judges Case"
Holding: Reverses the First Judges Case — "consultation" effectively means "concurrence"; the CJI's recommendation (formed via consultation with senior colleagues) is binding on the President — establishes the Collegium system.
In re Special Reference 1 of 1998 — "Third Judges Case"
Holding: Expands the Collegium to CJI + 4 senior-most Supreme Court judges; requires the Collegium's opinion to be in writing.
Supreme Court Advocates-on-Record Association v. Union of India (2015) — "NJAC case"/"Fourth Judges Case"
Holding: Strikes down the 99th Constitutional Amendment and the National Judicial Appointments Commission Act, 2014 as unconstitutional — holds that judicial independence (which the executive-dominated NJAC threatened) is part of the basic structure. Restores the Collegium system.
