Separation of Powers in India

The separation of powers distributes legislative, executive and judicial functions among different organs to prevent the concentration or misuse of public power. In India, it is functional rather than watertight: each organ has a primary sphere, while constitutional checks and limited overlaps restrain institutional overreach.

Constitutional allocation of functions

The Constitution creates distinct institutions but does not impose absolute separation. In Ram Jawaya Kapur v. State of Punjab (1955), the Supreme Court observed that India does not follow a rigid separation, although each organ should respect the functions assigned to the others.

• Article 50 directs the State to separate the judiciary from the executive in the public services of the State.
• The executive is accountable to the legislature, while legislation and public expenditure require legislative authority.
• Articles 13, 32 and 226 empower constitutional courts to review state action against constitutional limitations.
• In L. Chandra Kumar v. Union of India (1997), judicial review under Articles 32 and 226 was recognised as part of the Constitution's basic structure.

Checks against institutional overreach

Separation restrains the executive and legislature through judicial review, while judicial power is limited by constitutional text, institutional competence and democratic accountability.

• Courts may invalidate action that violates fundamental rights, exceeds statutory authority, disregards mandatory procedure or is manifestly arbitrary.
• Courts ordinarily examine legality rather than prescribe priorities, allocate resources or replace a lawful policy with one they consider better.
• In BALCO Employees' Union v. Union of India (2002), the Supreme Court emphasised that courts should not interfere with economic policy merely because another policy may appear fairer or wiser.
• Judicial restraint prevents governance through continuing judicial supervision and preserves policy choices for elected, accountable institutions.

Application to policy and constitutional remedies

Policy formulation primarily belongs to the legislature and executive, but separation of powers does not immunise policy from constitutional review.

• Reservation policies remain reviewable under the equality framework of Articles 14, 15 and 16, although their design is primarily a legislative or executive responsibility.
• In exceptional rights-protection situations, courts may frame interim guidelines where legislation is absent, as in Vishaka v. State of Rajasthan (1997), but such directions cannot override enacted law.
• The proper judicial remedy generally corrects the constitutional defect while leaving lawful policy design to the competent political organ.
