The law of India is not just a static set of rules; it is a living, breathing entity that evolves with our society. The Supreme Court of India plays a pivotal role in this evolution, and its landmark judgments have fundamentally shaped our rights, governance, and daily lives.
For an MH CET Law aspirant, knowing these key judgments is not about memorizing case names and dates. It is about understanding the core legal principles that form the bedrock of our democracy. These cases are frequently referenced in the Legal Knowledge and even the Reading Comprehension sections. Let’s dive into some of the most influential judgments every law student must know. ๐๏ธ
1. Kesavananda Bharati v. State of Kerala (1973)
- The Core Issue: Can the Parliament amend any part of the Constitution, including Fundamental Rights?
- The Landmark Judgment: The Supreme Court, in a historic 7-6 decision, held that while the Parliament has the power to amend the Constitution, it cannot alter its “basic structure” or fundamental framework.
- Why it Matters: This case is arguably the most important in Indian constitutional history. It established the “Basic Structure Doctrine,” which acts as a shield protecting the core identity of our Constitution (e.g., democracy, federalism, secularism) from being destroyed by legislative amendments. It secured the supremacy of the Constitution.
2. Maneka Gandhi v. Union of India (1978)
- The Core Issue: Does the “procedure established by law” under Article 21 (Right to Life and Personal Liberty) have to be fair, just, and reasonable?
- The Landmark Judgment: The Court dramatically expanded the scope of Article 21. It ruled that the “procedure established by law” must not be arbitrary or unfair. The right to life is not merely about physical existence but includes the right to live with human dignity.
- Why it Matters: This judgment revolutionized constitutional law. It infused fairness and justice into legal procedures and made Article 21 a repository of many other rights, such as the right to a clean environment, the right to speedy trial, and more.
3. K.S. Puttaswamy v. Union of India (2017)
- The Core Issue: Is the right to privacy a Fundamental Right under the Indian Constitution?
- The Landmark Judgment: A nine-judge bench of the Supreme Court unanimously declared that the Right to Privacy is a Fundamental Right, intrinsic to the Right to Life and Personal Liberty under Article 21.
- Why it Matters: This is a watershed moment for individual liberty in the digital age. It provides a constitutional safeguard against arbitrary surveillance and intrusion into the personal lives of citizens by the state and private entities.
4. Navtej Singh Johar v. Union of India (2018)
- The Core Issue: Was Section 377 of the Indian Penal Code, which criminalized consensual homosexual acts between adults, constitutionally valid?
- The Landmark Judgment: The Supreme Court struck down the part of Section 377 that criminalized consensual adult gay sex, declaring it unconstitutional. The Court held that sexual orientation is a natural phenomenon and discrimination on this basis is a violation of the fundamental rights to equality, dignity, and privacy.
- Why it Matters: This judgment was a major victory for the LGBTQ+ community in India. It affirmed the rights of individuals to love whomever they choose and marked a significant step towards a more inclusive and equal society.

5. Shreya Singhal v. Union of India (2015)
- The Core Issue: Was Section 66A of the Information Technology Act, 2000, which allowed for the arrest of people for posting “offensive” content online, a violation of the freedom of speech?
- The Landmark Judgment: The Supreme Court struck down Section 66A in its entirety, calling it vague, overbroad, and a violation of the Fundamental Right to Freedom of Speech and Expression under Article 19(1)(a).
- Why it Matters: This judgment is a cornerstone of online free speech in India. It protects citizens from arbitrary arrests for expressing their views on the internet and draws a clear line between advocacy and incitement.
6. Vishakha v. State of Rajasthan (1997)
- The Core Issue: What legal recourse is available against sexual harassment of women at the workplace in the absence of any specific law?
- The Landmark Judgment: In the absence of a law, the Supreme Court laid down a set of guidelines, known as the “Vishakha Guidelines,” to prevent and address sexual harassment at the workplace. These guidelines were legally binding until a formal law was enacted.
- Why it Matters: This is a powerful example of judicial activism. The Court stepped in to fill a legislative vacuum and protect the fundamental rights of working women. These guidelines formed the basis for the Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal) Act of 2013.
7. Indra Sawhney v. Union of India (1992)
- The Core Issue: What is the constitutional validity of reservations for Other Backward Classes (OBCs) as recommended by the Mandal Commission?
- The Landmark Judgment: The Court upheld the provision of 27% reservation for OBCs in government jobs. However, it also laid down two crucial conditions: it introduced the concept of the “creamy layer” (excluding the affluent among OBCs from availing reservation) and ruled that the total reservation for all categories combined cannot exceed 50%.
- Why it Matters: This judgment continues to be the defining legal framework for reservation policy in India. It sought to balance the objective of social justice with the need for efficiency in administration.
8. Minerva Mills v. Union of India (1980)
- The Core Issue: Can Parliament, through constitutional amendments, give its amending power unlimited authority and remove judicial review?
- The Landmark Judgment: The Court struck down parts of the 42nd Amendment Act, 1976. It firmly established that the power of judicial review is a part of the “basic structure” of the Constitution and cannot be taken away by Parliament.
- Why it Matters: This case reinforced the supremacy of the Constitution and the role of the judiciary as its ultimate interpreter and guardian, strengthening the principles laid down in the Kesavananda Bharati case.
