Why this matters now
Separation of powers is a foundational GS-2 concept that underlies debates on judicial overreach, ordinances and executive accountability — tested for the doctrine and how India applies it.
The doctrine
Classically articulated by Montesquieu, the doctrine holds that the three functions of government should rest in separate organs so that power checks power. A rigid version exists in the US; the UK has a fusion of powers. India follows a balanced model with functional separation and overlaps.
Separation of powers in India
India does not follow a rigid separation. There are deliberate overlaps — the executive (Council of Ministers) is drawn from and accountable to the legislature; the judiciary makes rules and can review actions; the legislature exercises some judicial functions (privileges, impeachment). The Supreme Court has held separation of powers to be part of the basic structure (Kesavananda, Indira Gandhi v. Raj Narain).
Checks, balances and tensions
Checks and balances include judicial review (over laws and executive action), legislative oversight (questions, committees, no-confidence), and the executive’s role in appointments and ordinances. Tensions surface as judicial overreach, executive aggrandisement (ordinance route) and legislative excess — making the balance a live constitutional question.

Frequently asked questions
What is the separation of powers?
The division of government authority among the legislature, executive and judiciary, with checks and balances to prevent concentration of power.
