Constitutional Landmark Judgments in Indian Law
1. Kesavananda Bharati v. State of Kerala (1973)
Citation: AIR 1973 SC 1461; (1973) 4 SCC 225
Bench: 13-Judge Constitution Bench | Date: April 24, 1973
Facts
Sri Kesavananda Bharati, head of the Edneer Mutt in Kerala, challenged the 24th, 25th, and 29th Constitutional Amendments that sought to restrict fundamental rights. The Kerala Land Reforms Act threatened the Mutt’s land holdings, prompting the petition under Article 32.
Issues
Whether Parliament has unlimited power to amend the Constitution, including abolishing fundamental rights, or whether there are inherent constitutional limits.
Judgment
By a 7:6 majority, the Court held that Parliament’s amending power is limited by the basic structure doctrine. While Parliament can amend any provision, it cannot alter the Constitution’s basic features: judicial review, democracy, secularism, federalism, rule of law, and the balance between fundamental rights and directive principles.
Significance: This judgment established the foundational principle that certain constitutional features are unamendable and protect the Constitution from authoritarian assault.
2. Maneka Gandhi v. Union of India (1978)
Citation: AIR 1978 SC 597; (1978) 1 SCC 248
Bench: 7-Judge Constitution Bench | Date: January 25, 1978
Facts
Maneka Gandhi’s passport was impounded without providing reasons or opportunity to be heard under the Passports Act, 1967. The government declined to explain its action, citing public interest.
Issues
Whether the right to travel abroad is fundamental; whether “procedure established by law” under Article 21 merely requires any statutory procedure or a fair, reasonable procedure; and whether Articles 14, 19, and 21 are interconnected.
Judgment
In a unanimous landmark decision, the Court held that:
- “Procedure established by law” must be just, fair, and reasonable, not merely procedurally correct
- Articles 14, 19, and 21 form the “Golden Triangle” and must be read together
- Any law depriving personal liberty must satisfy all three provisions
- The right to travel abroad is fundamental under Article 21
- Principles of natural justice, particularly the right to be heard, are mandatory
The Court rejected the narrow interpretation from A.K. Gopalan (1950) that fundamental rights were mutually exclusive.
Significance: This judgment revolutionized fundamental rights jurisprudence, making them dynamic and expansive, enabling subsequent recognition of numerous unenumerated rights including privacy, clean water, speedy trial, and dignity.
3. D.K. Basu v. State of West Bengal (1997)
Citation: AIR 1997 SC 610; (1997) 1 SCC 416
Bench: Justice A.S. Anand and Justice Kuldip Singh | Date: December 18, 1996
Facts
D.K. Basu, Executive Chairman of Legal Aid Services, filed a Public Interest Litigation alleging custodial deaths and torture in police lock-ups across states. He urged the Court to formulate custody guidelines and compensation mechanisms.
Issues
Whether custodial violence violates Article 21; whether arrested persons retain fundamental rights in custody; and what procedural safeguards are necessary to prevent custodial abuse.
Judgment
The Court held that persons in custody retain fundamental rights under Articles 21 and 22(1). Custodial violence constitutes grave constitutional violation. The Court mandated 11 binding procedural safeguards:
- Visible identification name tags for all police personnel
- Arrest memo signed by witness and provided to arrestee
- Right to inform a friend or relative of arrest
- Notification to magistrate within 8-12 hours if informant is outside the district
- Medical examination every 48 hours with memo signed by both parties
- Copies of documents sent to magistrate
- Access to legal counsel during interrogation
- Information board at police stations listing rights
- Regular magistrate inspections of lock-ups
- Police control rooms recording arrest information
- State vicariously liable for custodial violations; violations attract contempt consequences
Significance: This judgment created India’s “custodial jurisprudence,” providing enforceable protections against state abuse and serving as a powerful deterrent against police brutality.
4. Minerva Mills Ltd. v. Union of India (1980)
Citation: AIR 1980 SC 1789; (1980) 2 SCC 591
Bench: 5-Judge Constitution Bench | Date: July 31, 1980
Facts
Minerva Mills challenged the 42nd Amendment (passed during the Emergency) and the nationalization of the textile undertaking. The amendment sought to place constitutional amendments beyond judicial review and give all Directive Principles primacy over Fundamental Rights.
Issues
Whether Sections 4 and 55 of the 42nd Amendment damage the basic structure; whether removing judicial review violates the Constitution’s core; and whether Directive Principles can completely override Fundamental Rights.
Judgment
By 4:1 majority, the Court held that:
- Parliament’s amending power itself is limited and cannot be used to expand into unlimited power
- Sections 55 (inserting Article 368 clauses 4 and 5) are unconstitutional because they exclude judicial review, which is a basic structural feature
- Section 4 (expanded Article 31C) is unconstitutional because it destroys the harmonious balance between Fundamental Rights and Directive Principles
- Neither can have absolute primacy over the other
- Judicial review is inviolable and cannot be placed beyond constitutional scrutiny
The Court reaffirmed that India has a “controlled constitution” where all organs, including Parliament, must function within constitutional boundaries.
Significance: This judgment protected judicial independence post-Emergency and prevented authoritarian consolidation of power, reestablishing that constitutional limits on amendment power are non-negotiable.
5. Justice K.S. Puttaswamy v. Union of India (2017)
Citation: (2017) 10 SCC 1
Bench: 9-Judge Constitution Bench | Date: August 24, 2017
Facts
Justice Puttaswamy challenged the Aadhaar biometric identification scheme, arguing that mandatory data collection violated privacy. The challenge directly confronted two earlier 6 and 8-judge bench decisions denying constitutional privacy protection.
Issues
Whether privacy is a fundamental right; if so, whether it derives from existing provisions or is independent; and what is its scope in the digital age.
Judgment
In a historic unanimous judgment, all nine judges recognized privacy as fundamental:
- Privacy is an intrinsic part of Article 21 (right to life and personal liberty) and Part III fundamental rights
- M.P. Sharma (1954) and Kharak Singh (1962) are overruled to the extent they denied privacy protection
- Privacy encompasses: personal autonomy, bodily integrity, informational privacy, choice in personal matters, and sexual orientation
- Not an absolute right—State can limit privacy if it meets three conditions: (1) legality (must be law-based), (2) necessity (legitimate aim like national security), and (3) proportionality (rational nexus and reasonable restriction)
- Sexual orientation is core to privacy; discrimination based on it violates dignity
Significance: This watershed judgment recognized privacy as fundamental after decades of uncertainty, protected individual autonomy from surveillance, advanced LGBTQ+ rights, and laid the constitutional foundation for data protection in the digital age.
6. Indra Sawhney v. Union of India (1992) [Mandal Commission Case]
Citation: AIR 1993 SC 477; (1992) Supp. 3 SCC 217
Bench: 9-Judge Constitution Bench | Date: November 16, 1992
Facts
The Mandal Commission (1979) recommended 27% OBC reservation in central government jobs, in addition to 15% SC and 7.5% ST reservations. The Government of India implemented these recommendations in 1990, sparking widespread protests and leading to constitutional challenge by upper-caste groups.
Issues
Whether caste is valid criterion for identifying backwardness; whether 27% OBC reservation exceeds permissible limits; what is the maximum permissible total reservation; and whether economically advanced backward class members should be excluded.
Judgment
By 6:3 majority, the Court held:
- 27% OBC reservation is constitutionally valid
- Total reservations cannot exceed 50%—this is a constitutional ceiling, not exception
- Caste is valid criterion for identifying social and educational backwardness in Indian context, though not sole criterion
- “Creamy layer” within backward classes must be excluded to ensure benefits reach genuinely disadvantaged
- Article 16(4) is not exception to Article 16(1) but instance of equality of opportunity
- Reservations in promotions not allowed under Article 16(4) (subsequently modified by 77th Amendment allowing SC/ST promotion reservations)
Creamy Layer Concept: The most significant innovation was excluding affluent and advanced members of OBC from reservation benefits using income criteria (initially Rs. 1 lakh, later revised).
Significance: This judgment established modern affirmative action jurisprudence, balancing social justice with merit, and defining equitable reservation policy that has governed India’s approach to social equity for three decades.
Conclusion
These six constitutional landmarks form the backbone of Indian constitutional law. Kesavananda Bharati and Minerva Mills established immutable constitutional limits protecting democracy against authoritarian assault. Maneka Gandhi transformed fundamental rights into dynamic protections of human dignity and personal liberty. D.K. Basu created enforceable safeguards against state violence. Puttaswamy recognized privacy as fundamental in the digital age. Indra Sawhney defined equitable affirmative action balancing social justice with merit. Together, they demonstrate the Supreme Court’s role as the Constitution’s guardian, ensuring India remains a vibrant constitutional democracy governed by rule of law.
