Separation of Powers in India

The separation of powers distributes legislative, executive and judicial functions among different organs to prevent concentration or misuse of public power. In India, the separation is functional rather than watertight: institutional overlap and constitutional checks coexist with judicial independence.

Constitutional design and judicial independence

The Constitution creates distinct organs without imposing rigid separation. In Ram Jawaya Kapur v. State of Punjab (1955), the Supreme Court held that 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.
• Judges are appointed under Articles 124 and 217; the collegium system gives the judiciary institutional primacy in recommendations.
• Judges have security of tenure, protected service conditions and a removal process requiring special parliamentary majorities; Articles 121 and 211 restrict legislative discussion of their conduct except during removal.

Judicial review and institutional checks

In L. Chandra Kumar v. Union of India (1997), judicial review under Articles 32 and 226 was recognised as part of the basic structure.

• Courts may invalidate state action that violates fundamental rights, exceeds statutory authority, disregards mandatory procedure or is manifestly arbitrary.
• The executive is accountable to the legislature, while legislation and public expenditure require legislative authority.
• High Courts control district and subordinate courts under Article 235, strengthening judicial independence.

Judicial restraint in policy and criminal law

Courts review legality and constitutionality, but policy formulation and creation of offences primarily belong to the elected branches.

• Courts ordinarily cannot prescribe policy priorities, allocate resources or replace a lawful policy merely because another appears better; BALCO Employees' Union v. Union of India (2002) applied this restraint to economic policy.
• Reservation design primarily belongs to the legislature or executive, but remains reviewable under Articles 14, 15 and 16.
• Under Article 20(1), conviction requires violation of a law in force when the act occurred, and no greater retrospective penalty may be imposed.
• Courts may interpret penal provisions or invalidate unconstitutional ones, but cannot add missing ingredients, create a new offence or prescribe a new punishment; Article 142 cannot supplant substantive criminal law.
• In a legislative vacuum, courts may issue rights-protecting interim guidelines, as in Vishaka v. State of Rajasthan (1997), but these cannot override enacted law or invent criminal liability.
