If one person or body could make laws, carry them out and also judge disputes about them, there would be no protection against misuse of power. The idea of separation of powers divides government into three organs - the legislature, the executive and the judiciary - so that each checks the others. India follows this idea, but not in a rigid way. Exams ask about its origin, the Articles that reflect it, checks and balances, and key cases. This post explains them in simple words. It ends with 15 previous year questions.
Key Points (Quick Revision)
- The theory of separation of powers was given by Montesquieu in The Spirit of the Laws (1748).
- India has no rigid separation; the organs work separately but also check each other.
- Article 50 asks the State to separate the judiciary from the executive.
- In the Kesavananda Bharati case (1973), separation of powers was held to be part of the basic structure.
- India's system is better described as checks and balances.
1. The three organs
| Organ | Main function | In India |
|---|---|---|
| Legislature | Makes laws | Parliament and State Legislatures |
| Executive | Carries out laws and runs the government | President, Prime Minister and Council of Ministers; Governors and State governments |
| Judiciary | Interprets laws and settles disputes | Supreme Court, High Courts and lower courts |
2. Origin of the idea
The French thinker Montesquieu, in his book The Spirit of the Laws (1748), argued that liberty is safe only when legislative, executive and judicial powers are held by different bodies. The United States Constitution follows this idea closely, with a President separate from Congress. The British parliamentary system, which India largely follows, has a closer link between the legislature and the executive.
3. Separation in the Indian Constitution
- Article 50 - the State shall separate the judiciary from the executive in public services.
- Articles 121 and 211 - Parliament and State Legislatures cannot discuss the conduct of judges, except in a motion for removal.
- Articles 122 and 212 - courts cannot question the validity of proceedings of Parliament and State Legislatures.
- Articles 53 and 154 - executive power of the Union and States rests with the President and Governors.
- Article 361 - the President and Governors are not answerable to any court for the exercise of their powers.
4. Checks and balances
| Check | By whom, on whom |
|---|---|
| Judicial review (Articles 13, 32, 226) | Judiciary can strike down laws and actions that violate the Constitution |
| No-confidence motion, questions and debates | Legislature keeps the executive answerable |
| Impeachment of the President (Article 61) | Legislature on the executive head |
| Removal of judges (Article 124(4)) | Legislature on the judiciary |
| Ordinances (Article 123) and assent to bills | Executive's role in law-making |
| Appointment of judges | Executive formally appoints, on the collegium's recommendation |
5. Overlaps in India
- Ministers are members of the legislature - the executive comes from the legislature.
- The executive makes rules and regulations under laws (delegated legislation).
- Tribunals run by the executive decide some disputes.
- Courts sometimes give directions on policy issues through PILs.
These overlaps show that India follows a functional separation rather than a strict one.
6. Key cases
| Case | Year | Point |
|---|---|---|
| Ram Jawaya Kapur v. State of Punjab | 1955 | The Constitution does not follow a rigid separation, but functions are broadly divided |
| Kesavananda Bharati v. State of Kerala | 1973 | Separation of powers is part of the basic structure |
| Indira Gandhi v. Raj Narain | 1975 | Parliament cannot take over judicial functions; struck down a clause that put an election beyond court review |
7. Judicial activism and overreach
Judicial activism means courts actively protecting rights, for example through PILs on pollution, prisoners' rights and food security. Critics warn against judicial overreach, when courts step into areas that belong to the legislature or executive. Balancing activism with restraint is a key part of keeping the separation of powers healthy.

9. How to revise this topic
Start with the idea: Montesquieu, The Spirit of the Laws, 1748; three organs.
Next, learn the Articles: 50 (judiciary separate from executive), 121/211, 122/212, 53/154, 361.
Then fix the checks: judicial review (13, 32, 226), impeachment (61), removal of judges (124(4)), no-confidence motion, ordinances (123).
Finally, remember the cases: Ram Jawaya Kapur 1955, Kesavananda 1973, Indira Gandhi v. Raj Narain 1975; and the terms judicial activism and overreach.
10. Frequently Asked Questions
What is separation of powers?
It is the idea that the legislature, executive and judiciary should have separate functions so that no one organ becomes too powerful. It was explained by Montesquieu in 1748.

Which Article deals with separation of the judiciary from the executive?
Article 50, a Directive Principle, asks the State to separate the judiciary from the executive in the public services.
Is separation of powers part of the basic structure?
Yes. In the Kesavananda Bharati case of 1973, the Supreme Court held separation of powers to be part of the basic structure of the Constitution.
