Amendments to Indian Constitution: Important List

India’s Constitution has been amended 106 times since it came into force on 26 January 1950. That’s a significant number — the US Constitution has been amended only 27 times in over 230 years. This reflects the framers’ deliberate choice to make the Constitution a living document, adaptable to changing social, economic, and political realities. But the amendment power is not unlimited. The basic structure doctrine — evolved by the Supreme Court — sets the outer boundary of what Parliament can change. Understanding the amendment process, the key amendments, and this boundary is essential for UPSC.

The Amendment Process: Article 368

Article 368 in Part XX of the Constitution governs how it can be amended. The procedure depends on the type of provision being amended.

Three Methods of Amendment

Method 1: Simple Majority (Not Article 368)

Some provisions can be amended by a simple majority of Parliament — meaning the same majority needed to pass an ordinary law. These are not considered constitutional amendments under Article 368. Examples:

Method 2: Special Majority (Article 368)

Most constitutional provisions require a special majority:

Method 3: Special Majority + Ratification by States

Certain provisions additionally require ratification by not less than half of the state legislatures before the President can give assent. These include provisions affecting the federal structure:

There is no provision for a joint sitting of Parliament to resolve a deadlock on a constitutional amendment bill (unlike ordinary bills).

Role of the President

Once passed by Parliament (and ratified by states where required), the bill is presented to the President. The President must give assent — they cannot withhold or return a constitutional amendment bill. This was confirmed after the 24th Amendment (1971), which made it explicit that the President shall give assent.

Article 368 amendment flow: special majority, state ratification and mandatory presidential assent.

The Basic Structure Doctrine

Before diving into individual amendments, you must understand the basic structure doctrine — because it’s the most important constraint on Parliament’s amendment power.

Kesavananda Bharati v. State of Kerala (1973)

In this landmark 13-judge bench ruling, the Supreme Court held by a 7-6 majority that while Parliament has wide power to amend the Constitution under Article 368, it cannot destroy the basic structure or essential features of the Constitution.

The Court did not define basic structure exhaustively, but elements held to be part of it include:

Any constitutional amendment that destroys any of these elements can be struck down by the Supreme Court. This is the final limit on Parliament’s amending power.

The 42nd Amendment: The “Mini-Constitution”

The 42nd Constitutional Amendment Act, 1976 — passed during the Emergency by the Indira Gandhi government — was the most sweeping constitutional change in Indian history. It:

  1. Added “Socialist” and “Secular” to the Preamble
  2. Added “Integrity” alongside “Unity” in the Preamble
  3. Added Fundamental Duties (Part IVA, Article 51A) — 10 duties for citizens
  4. Gave primacy to Directive Principles over Fundamental Rights (Article 31C expanded)
  5. Made constitutional amendments non-justiciable (Parliament’s amending power made absolute)
  6. Extended the life of Lok Sabha and state assemblies from 5 to 6 years
  7. Extended President’s Rule from 1 year to 2 years in a state
  8. Curtailed judicial review of central and state laws
  9. Inserted a chapter on Fundamental Duties
  10. Established the Administrative Tribunals (Article 323A-B)

Many of these changes were reversed by the 44th Amendment (1978) after the Janata government came to power:

The 44th Amendment: Restoring Constitutional Balance

The 44th Constitutional Amendment Act, 1978 was the democratic correction to Emergency-era excesses:

  1. Right to Property removed from Fundamental Rights — made only a legal right under Article 300A (cannot be taken away without authority of law)
  2. Restored pre-Emergency protection against arbitrary detention (Articles 20, 21 cannot be suspended even during Emergency)
  3. Strengthened safeguards before President can proclaim Emergency under Article 352:
Key changes made by the 44th Constitutional Amendment, 1978.

– Written advice of Cabinet (not just PM) required – Lok Sabha approval within one month – Emergency can be revoked by simple majority in Lok Sabha

  1. Restored freedom of the press
  2. Made Presidential satisfaction regarding President’s Rule justiciable

The 73rd and 74th Amendments: Decentralisation

The 73rd Amendment (1992) gave constitutional recognition to Panchayati Raj:

The 74th Amendment (1992) did the same for urban local bodies:

These amendments are among the most significant for local self-governance in India’s post-independence history.

The 101st Amendment: GST

The 101st Constitutional Amendment Act, 2016 transformed India’s indirect tax system:

The GST Council must make decisions with a 3/4th majority — Centre has 1/3rd of voting power; all states together have 2/3rd.

The 103rd Amendment: EWS Reservation

The 103rd Constitutional Amendment Act, 2019 provided for 10% reservation for Economically Weaker Sections (EWS) in educational institutions and public employment:

The 106th Amendment: Women’s Reservation

The 106th Constitutional Amendment Act, 2023 — known as the Nari Shakti Vandan Adhiniyam — reserved one-third of seats in the Lok Sabha and state legislative assemblies for women.

Frequently Asked Questions

Q1. What is the basic structure doctrine and how did it emerge?

The basic structure doctrine holds that Parliament cannot amend the Constitution to destroy its essential features. It emerged from the Supreme Court’s 13-judge bench ruling in

Kesavananda Bharati v. State of Kerala (1973), where the Court held that while Parliament’s amending power is wide, certain features are indestructible. The Court built on an earlier hint in Golak Nath v. State of Punjab (1967), which the 24th Amendment tried to overrule, prompting the definitive Kesavananda ruling.nnQ2. Can Fundamental Rights be amended?

Yes, with a special majority under Article 368. But the core of Fundamental Rights is part of the basic structure and cannot be destroyed — even by amendment. The Court will invalidate amendments that abridge Fundamental Rights to the point of making them meaningless.

Q3. Why is the Ninth Schedule significant?

The Ninth Schedule contains laws that are protected from judicial review on grounds of violation of Fundamental Rights. It was created by the 1st Amendment to protect land reform laws. But the Supreme Court in

I.R. Coelho v. State of Tamil Nadu (2007) held that laws placed in the Ninth Schedule after 24 April 1973 (Kesavananda date) can still be challenged if they violate the basic structure.nnQ4. What does u0022ratification by statesu0022 mean in the amendment process?

For amendments affecting federal provisions, the amendment bill must be ratified by the legislatures of not less than half the states before it is presented to the President. The ratification must happen before Presidential assent. If a state revokes its ratification before the Presidential assent, it’s unclear constitutionally whether that withdrawal is valid — a grey area in practice.

Q5. Is the Preamble part of the Constitution and can it be amended?

Yes to both. The Supreme Court in
