Separation of Powers (India, UK, USA) — Administrative Law Notes

Separation of Powers (India, UK, USA)

In 1748 the French thinker Montesquieu, studying the English constitution, warned in The Spirit of the Laws: “There can be no liberty where the legislative and executive powers are united in the same person… and there would be an end of everything, were the same body to exercise these three powers.” Concentrate all power in one hand, he said, and tyranny follows. The idea crossed the Atlantic and became the backbone of the American Constitution — yet, ironically, the English constitution Montesquieu praised never really separated its powers at all.

What is the doctrine of Separation of Powers?

The State exercises three kinds of power: it makes law (legislative), it executes law (executive), and it decides disputes under law (judicial). The doctrine of separation of powers says these three functions should be kept in three separate organs, so that no single organ becomes all-powerful — power checks power, and liberty survives.

The doctrine has three strict propositions:

The same person should not form part of more than one organ — a minister (executive) should not sit as a judge.
One organ should not control or interfere with another — the executive should not dictate to the courts.
One organ should not exercise the functions of another — the executive should not legislate or adjudicate.

Read strictly, no modern State obeys all three — government would grind to a halt. So the doctrine survives everywhere in a diluted form, as a system of checks and balances: the organs overlap deliberately, each holding a partial check on the others.

A. The doctrine in the UK, USA and India

United Kingdom. Separation is weakest. The executive (the Cabinet) is drawn from and sits in the legislature (Parliament); Parliament is supreme; historically the Lord Chancellor sat in all three branches. The UK relies on conventions and parliamentary responsibility, not on a formal separation.
United States. Separation is strongest and written. The President (executive) is not a member of Congress; judges are independent; each branch checks the others (Presidential veto, Senate confirmation, judicial review from Marbury v Madison (1803)). Even so, absolute separation is impossible — hence “checks and balances”.
India. A middle path. There is no rigid separation, but a broad functional separation with strong checks:
- Article 50 directs the State to separate the judiciary from the executive.
- Articles 121 and 211 bar discussion in the legislatures of a judge’s conduct.
- Articles 122 and 212 bar the courts from questioning parliamentary/legislative proceedings.
- Article 361 gives the President and Governors immunity from court process for official acts.
- Judicial review keeps the other two organs within the Constitution; the judiciary’s independence and the basic-structure doctrine protect the scheme.

The blending is obvious: the executive makes law (delegated legislation), tribunals (executive) decide disputes, and the President has legislative (ordinance, Art. 123) and judicial (pardon, Art. 72) roles. India therefore follows separation of powers in a broad sense — not as a rigid rule but as a working division with checks and balances.

⚠️ Do NOT write that India follows a rigid or complete separation of powers. It does not. The correct line, approved by the Supreme Court, is that there is no strict separation in India, but the doctrine’s core — that no one organ may usurp the essential functions of another — is part of the basic structure.

Article 50: “The State shall take steps to separate the judiciary from the executive in the public services of the State.”

In Simple Terms: Split the three powers of the State among three organs so no one organ turns tyrant. No country does this perfectly — the UK barely tries, the USA does it most strictly, and India takes the middle road: no rigid wall, but a working separation with judicial review and a set of constitutional checks.

🧩 WORKED EXAMPLE — Does this violate separation of powers?

Facts. Parliament passes a law that itself declares a named person guilty and imposes a punishment, and further sets aside a specific court judgment.

Rule. In India the essential functions of one organ cannot be usurped by another — deciding guilt and adjudicating a specific dispute are judicial functions.

Apply. By convicting a named person and reversing a judgment, the legislature has exercised a judicial function. This crosses from law-making into judging — the core the doctrine protects.

Conclusion. The law is bad. As Indira Nehru Gandhi v Raj Narain (1975) held, a legislature cannot decide a specific dispute judicially; that violates the separation of powers, a part of the basic structure.

Case Laws

Ram Jawaya Kapur v State of Punjab (1955) — India does not follow a rigid separation of powers, but the functions are broadly differentiated.
Indira Nehru Gandhi v Raj Narain (1975) — a legislature cannot exercise a judicial function and decide a specific dispute; separation of powers is basic structure.
Kesavananda Bharati v State of Kerala (1973) — separation of powers is part of the basic structure of the Constitution.
I.R. Coelho v State of Tamil Nadu (2007) — reaffirmed judicial review and separation of powers as basic features.
