If you are studying law in India, there are some Supreme Court judgments that you will encounter again and again. They appear in constitutional law classes, university examinations, moot court propositions, judiciary preparation, internship discussions and even law firm interviews.
The important thing is not simply remembering the names of landmark Supreme Court cases. You need to understand what changed because of each judgment, which constitutional principle emerged from it and why courts continue to refer to it.
Think of these cases as the foundation of your constitutional law knowledge. Once these judgments are clear, concepts such as the Basic Structure Doctrine, Article 21, judicial review, federalism and the right to privacy become considerably easier to understand.
Here are five landmark judgments of the Supreme Court of India that every law student should know.
Why should every law student study landmark Supreme Court judgments?
Reading judgments teaches you something that textbooks alone cannot. A textbook tells you what the law is. A judgment helps you understand how courts reach that law.
When you read important Supreme Court judgments, you begin to see how constitutional provisions are interpreted, how competing rights are balanced and how legal principles develop over time.
This is why learning landmark cases should not become an exercise in memorising case names and years.
As a law student, try asking four questions whenever you study an important judgment:
- What was the main constitutional or legal issue before the Court?
- What did the Supreme Court ultimately decide?
- Which legal principle emerged from the judgment?
- Why does that principle continue to matter today?
If you are just beginning to build this habit, this guide on landmark judgements every law student must read can help you expand your case law reading list beyond the five judgments discussed here.
Which 5 Supreme Court cases should every law student know?
There are hundreds of important Supreme Court judgments in Indian law. However, these five cases provide an excellent starting point because each explains a constitutional principle that continues to influence Indian law.
1. What should you know about Kesavananda Bharati v. State of Kerala?
Kesavananda Bharati v. State of Kerala, 1973 is one of the most important constitutional law cases in India.
The case concerned the extent of Parliament’s power to amend the Constitution under Article 368. A thirteen judge Bench of the Supreme Court considered whether Parliament’s constitutional amendment power was unlimited.
The judgment resulted in what is now known as the Basic Structure Doctrine. Although Parliament has wide powers to amend the Constitution, its amending power cannot be used to destroy the basic structure or identity of the Constitution. The Supreme Court itself describes Kesavananda Bharati as the judgment associated with the Basic Structure Doctrine.
For a law student, the most important point is not simply:
Kesavananda Bharati = Basic Structure Doctrine.
You should understand the larger constitutional conflict behind the case. Parliament has the power to amend the Constitution, but that power exists within a constitutional system. The doctrine prevents the amendment power from becoming a power to replace the Constitution with something fundamentally different.
Later judgments have developed the doctrine further and identified features such as judicial review, constitutional supremacy and other foundational principles within the basic structure framework.
What should you remember?
Parliament can amend the Constitution, but its constituent power is not unlimited.
2. Why is Maneka Gandhi v. Union of India important for Article 21?
If Article 21 appears anywhere in your constitutional law syllabus, Maneka Gandhi v. Union of India, 1978 is a case you should understand properly.
Article 21 states that no person shall be deprived of life or personal liberty except according to procedure established by law.
The significance of Maneka Gandhi lies in the Supreme Court’s broader understanding of this protection. The procedure through which personal liberty is restricted cannot merely exist formally in legislation. It must satisfy standards of fairness and non-arbitrariness.
The judgment became central to the development of the idea that a procedure affecting life or personal liberty must be just, fair and reasonable.
It also strengthened the relationship between Articles 14, 19 and 21. Rather than treating fundamental rights as isolated compartments, constitutional scrutiny increasingly examined how these protections interact.
This becomes particularly important when studying later Article 21 jurisprudence involving dignity, autonomy, privacy and personal liberty.
What should you remember?
Maneka Gandhi transformed Article 21 from a narrow procedural guarantee into one of the most important sources of rights-based constitutional jurisprudence in India.
3. Why should you remember Vishaka v. State of Rajasthan?
Vishaka v. State of Rajasthan, 1997 is essential for understanding fundamental rights, gender justice and the role courts may play when a legislative framework is absent.
At the time of the judgment, India did not have specific legislation comprehensively regulating sexual harassment of women at the workplace.
The Supreme Court framed what became known as the Vishaka Guidelines to address workplace sexual harassment.
These guidelines operated as the governing framework until Parliament enacted legislation dealing specifically with the subject. The eventual statutory framework came through the Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal) Act, 2013.
The importance of Vishaka extends beyond remembering the guidelines themselves.
It demonstrates how constitutional protections relating to equality, dignity and professional participation can operate in real-life situations. It also helps students understand the interaction between constitutional rights, international norms and judicial remedies.
What should you remember?
Vishaka is a key judgment for studying workplace sexual harassment, gender equality and judicial guidelines in the absence of specific legislation.
4. What does S.R. Bommai v. Union of India teach you about federalism?
S.R. Bommai v. Union of India, 1994 should be on your list whenever you study Indian federalism and Article 356.
Article 356 deals with situations involving the failure of constitutional machinery in a State and provides for what is commonly called President’s Rule.
The constitutional question is important because the provision gives the Union significant power affecting an elected State government.
S.R. Bommai placed important constitutional limitations around the exercise of this power. One of its major contributions was establishing that a proclamation under Article 356 is not beyond judicial scrutiny.
The case is therefore closely associated with judicial review, federalism and constitutional limits on central power.
It is also regularly discussed while studying secularism within Indian constitutional law.
You should connect this case with a wider constitutional principle: government power does not automatically become immune from judicial review merely because the Constitution grants that power to a high constitutional authority.
What should you remember?
S.R. Bommai is a foundational case for understanding Article 356, judicial review and Centre-State constitutional relations.
5. Why is Justice K.S. Puttaswamy v. Union of India important today?
Few constitutional judgments feel as relevant to modern life as Justice K.S. Puttaswamy v. Union of India, 2017.
A nine judge Constitution Bench unanimously recognised the right to privacy as a fundamental right.
The judgment connected privacy with life, liberty, dignity and other fundamental freedoms protected by Part III of the Constitution. Subsequent Supreme Court decisions have continued to describe privacy as an intrinsic facet of Article 21.
Why should this case matter to you beyond your constitutional law examination?
Because questions of privacy now arise almost everywhere:
- personal data;
- technology;
- surveillance;
- bodily autonomy;
- informational privacy;
- individual choice;
- digital identity; and
- State access to personal information.
Puttaswamy gives you a constitutional framework through which many of these modern legal questions can be examined.
The judgment also explains that privacy is not absolute. Restrictions interfering with privacy must satisfy constitutional requirements, including legality and proportionality.
What should you remember?
Puttaswamy firmly established privacy within the framework of constitutionally protected fundamental rights.
How should you study these Supreme Court cases instead of simply memorising them?
Knowing the case name and one legal principle is useful for quick revision, but it is not enough for serious legal study.
For every landmark judgment, create a short case brief containing:
- Facts: What happened?
- Issue: What legal question did the Court have to decide?
- Arguments: What were the competing positions?
- Judgment: What did the Court decide?
- Reasoning: Why did the Court reach that conclusion?
- Ratio decidendi: What binding legal principle emerged?
- Significance: How did the judgment change or develop the law?
You can use this step-by-step guide on how to brief a case to develop a consistent method for analysing judgments. A proper case brief focuses particularly on material facts, the legal question, reasoning, ratio and outcome rather than copying the entire judgment.
More importantly, read at least the relevant portions of the original judgment whenever a case is important for an exam, moot, research paper or legal argument. Headnotes and summaries are useful starting points, but they should not replace the judgment itself.
What mistakes should you avoid while studying landmark judgments?
One common mistake is reducing every case to a single sentence.
For example:
“Kesavananda Bharati introduced Basic Structure.”
“Puttaswamy recognised privacy.”
These statements may be useful for last-minute revision, but they do not show that you understand the case.
Another mistake is reading the facts without identifying the actual legal issue. Law students sometimes remember the story of a dispute but struggle to explain why the judgment became a precedent.
You should also avoid treating every observation made by a court as the ratio decidendi. Learning to distinguish the binding principle from additional judicial observations is an essential case-reading skill.
The LawMento guide on common mistakes students make while reading case laws explains why students need to move beyond reading judgments like stories and learn to identify issues, reasoning and binding principles.
How can you quickly revise these five landmark cases?
A simple five-line revision framework can help:
| Supreme Court Case | Principle to Remember |
|---|---|
| Kesavananda Bharati v. State of Kerala | Basic Structure Doctrine |
| Maneka Gandhi v. Union of India | Article 21 and fair, just and reasonable procedure |
| Vishaka v. State of Rajasthan | Workplace sexual harassment and judicial guidelines |
| S.R. Bommai v. Union of India | Article 356, judicial review and federalism |
| Justice K.S. Puttaswamy v. Union of India | Fundamental Right to Privacy |
Use this table for revision, but not as a substitute for understanding the judgments.
A good test is simple: if someone mentions one of these cases, can you explain its issue, holding and significance in about one minute without checking your notes?
If yes, you probably understand the case.
If not, return to the judgment and prepare a short case brief.
Final Thoughts
The best law students do not build their knowledge by memorising hundreds of case names. They build it by understanding a smaller number of foundational judgments deeply and then connecting newer cases to those principles.
Kesavananda Bharati teaches you about constitutional limitations. Maneka Gandhi helps you understand personal liberty. Vishaka shows constitutional rights operating in the workplace. S.R. Bommai explains federalism and judicial review. Puttaswamy brings constitutional liberty into the age of privacy and technology.
Start with these five Supreme Court cases, learn their reasoning rather than just their keywords, and gradually build your own bank of landmark judgments.
