It was established by the Supreme Court in:

Kesavananda Bharati v. State of Kerala, 1973

The doctrine means:

Parliament can amend the Constitution, but cannot destroy its Basic Structure.

Basic Structure → Limit on Amending Power

Judicial Review → Enforcement

Constitution → Supreme


1. Meaning of Basic Structure

2. Constitutional Basis

The doctrine is primarily connected with:

The Court reaffirmed:

Limited Amending Power + Judicial Review

6. What Parliament Can Do

Parliament can:

  • Amend constitutional provisions
  • Modify institutional arrangements

The list is:

9. Supremacy of the Constitution

The Constitution is the:

Supreme Law

All organs of government derive their authority from it.

Therefore:

Parliament is subject to the Constitution

Memory

Constitution → Supreme

Parliament → Constitutionally Limited


10. Rule of Law

Rule of Law means:

Government Power Is Subject to Law

The Basic Structure Doctrine prevents Parliament from using constitutional amendment power to create:

Unlimited Government Power


11. Democracy

Democracy is part of the:

Basic Structure

A temporary parliamentary majority cannot use constitutional amendment to permanently eliminate:

Democratic Government

Core Principle

Majority Rule + Constitutional Limits = Constitutional Democracy

An amendment cannot fundamentally transform India into a:

The constitutional identity of India cannot be fundamentally altered to destroy:

Secularism

Memory

Secularism → Basic Structure

Basic Structure

The Constitution distributes powers between:

Union + States

This federal character cannot be completely destroyed through constitutional amendment.

Important Case

S.R. Bommai v. Union of India, 1994


15. Separation of Powers

The Constitution distributes power among:

  • Legislature
  • Executive
  • Judiciary

This institutional division forms an important part of constitutionalism.

Core Principle

No Single Institution Should Become Constitutionally Unlimited


16. Judicial Review

Judicial Review means:

Courts Can Examine Constitutional Validity

Judicial Review is part of:

Basic Structure

Therefore Parliament cannot completely eliminate Judicial Review through constitutional amendment.

Important Case

Minerva Mills, 1980


17. Judicial Independence

An independent Judiciary is necessary for:

  • Constitutional interpretation

Therefore:

Democratic Government

In:

Indira Gandhi v. Raj Narain, 1975

Parliament's power to amend the Constitution is itself:

Limited

In:

Minerva Mills, 1980

the Court held that:

Limited Amending Power

forms part of the Basic Structure.

Important Principle

Parliament Cannot Use Article 368 to Make Article 368 Unlimited


20. Basic Structure and Fundamental Rights

The constitutional position is:

Fundamental Rights Can Be Amended

but:

Basic Structure Cannot Be Destroyed

The doctrine therefore protects the essential constitutional framework within which Fundamental Rights operate.

Historical Evolution

Golaknath → Fundamental Rights Amendment Restricted

Kesavananda → Amendment Permitted Subject to Basic Structure


21. Basic Structure and Directive Principles

The Constitution contains:

Fundamental Rights

and:

Directive Principles of State Policy

The Supreme Court has emphasised:

between them.

  • Liberty
  • Equality
  • Fraternity
  • Democracy
  • Republic
  • Secularism

The Preamble helps identify:

and:

Article 368(5)

to restrict judicial review and assert broad amending power.

These provisions were struck down in:

Minerva Mills, 1980

Memory

42nd Amendment → Attempted Expansion

Minerva Mills → Limited Amending Power


27. 24th Constitutional Amendment

The:

The Ninth Schedule continues to exist.

Article 31B continues to operate.

However, relevant post-24 April 1973 laws are not automatically immune from:

The Constitution Is Supreme

Essential Constitutional Features Cannot Be Destroyed

Relationship

Constitutional Supremacy → Broad Principle

Basic Structure → Judicially Enforced Limitation


34. Basic Structure and Parliamentary Sovereignty

India follows:

rather than:

Absolute Parliamentary Sovereignty

Parliament has extensive power but remains:

Constitutionally Limited

Memory

Parliament → Powerful

Constitution → Supreme


35. Basic Structure and Judicial Supremacy

Judicial Supremacy

The Judiciary acts as:

Guardian and Interpreter of the Constitution

The ultimate authority remains:

The Constitution


36. Basic Structure and Constitutional Flexibility

The doctrine does not make the Constitution:

Completely Rigid

Parliament can still make:

Formula

Flexibility → Adaptation

Formula

↓

Change

↓

Basic Structure Boundary

↓

40. Criticism of the Doctrine

The doctrine has attracted several criticisms.

Judicial Overreach

Critics argue that the Judiciary exercises excessive power by invalidating amendments passed by elected representatives.

Lack of Explicit Text

The Constitution does not expressly mention:

Basic Structure

No Exhaustive Definition

There is no complete list of Basic Structure features.

Judicial Discretion

Different benches may identify different features.

Democratic Deficit

Unelected judges can invalidate constitutional amendments passed by elected representatives.

Potential Judicial Supremacy

Excessive use of the doctrine may raise concerns about:

Judicial Supremacy


41. Defence of the Doctrine

The doctrine can be defended because:

Democracy Is More Than Majority Rule

A temporary majority should not be able to destroy:

  • Elections
  • Rights
  • Rule of Law
  • Judicial Review
  • Federalism
  • Constitutional accountability

Core Argument

Constitutional Procedures Should Not Be Used to Destroy Constitutional Democracy.


42. Balanced Evaluation

along with:

rather than merely because judges disagree with:

Government Policy

Ideal Balance

Parliamentary Power + Judicial Restraint + Constitutional Supremacy

"The Basic Structure Doctrine, evolved by the Supreme Court in Kesavananda Bharati v.

Use:

"Constitutional change without constitutional destruction."
