Amendment of the Constitution (Article 368)

Introduction

The Constitution of India is a living and dynamic document. The framers recognised that society, economy, technology and governance would change over time. Therefore, they provided a constitutional mechanism to amend the Constitution while preserving its democratic values and fundamental principles.

The power to amend the Constitution is provided mainly under Article 368 in Part XX of the Constitution. This Article prescribes the procedure for constitutional amendments and enables Parliament to modify constitutional provisions according to the nation's changing needs.

Meaning of Constitutional Amendment

A Constitutional Amendment means a formal change, addition or repeal of one or more provisions of the Constitution through the procedure prescribed by the Constitution itself. It ensures that the Constitution remains relevant while maintaining constitutional stability.

Why are Constitutional Amendments Necessary?

• To meet changing social, political and economic needs.
• To strengthen democracy and good governance.
• To remove constitutional ambiguities.
• To implement judicial decisions.
• To protect Fundamental Rights and constitutional values.
• To accommodate administrative and federal changes.
• To address emerging national and global challenges.

Historical Background

The makers of the Constitution carefully studied the amendment procedures of several countries, including the United Kingdom, the United States, Canada, Australia and South Africa. They adopted a balanced approach by making the Indian Constitution neither too rigid nor too flexible.

Dr. B. R. Ambedkar described the Indian Constitution as a document capable of adapting to changing circumstances without losing its core democratic character.

Constitutional Framework

Objectives of Article 368

• Maintain constitutional stability.
• Allow peaceful constitutional evolution.

Constituent Power of Parliament

While exercising powers under Article 368, Parliament acts in its constituent capacity rather than its ordinary legislative capacity. This means Parliament follows a special constitutional procedure while amending the Constitution.

Learning Objectives

• Understand the meaning of Constitutional Amendment.
• Study Article 368 in detail.
• Know why constitutional amendments are necessary.
• Understand Parliament's constituent power.
• Prepare for UPSC Prelims, Mains and Interview.

UPSC Focus

Questions on Article 368, the amendment procedure and the Basic Structure Doctrine are among the most important topics in Indian Polity. UPSC frequently asks both conceptual and analytical questions on constitutional amendments.

Procedure for Constitutional Amendment (Article 368)

Article 368 provides the constitutional procedure for amending the Constitution of India. Depending on the subject matter, amendments may require a Simple Majority, a Special Majority of Parliament, or a Special Majority along with ratification by at least one-half of the State Legislatures.

Step-by-Step Amendment Procedure

1. A Constitution Amendment Bill may be introduced in either the Lok Sabha or the Rajya Sabha.
2. The Bill can be introduced only in Parliament; State Legislatures cannot introduce a Constitutional Amendment Bill.
3. No prior permission of the President is required to introduce the Bill.
4. The Bill must be passed by the required majority depending on the nature of the amendment.
5. For matters affecting the federal structure, ratification by at least one-half of the State Legislatures is also required.
6. After Parliament passes the Bill (and State ratification where required), it is presented to the President.
7. The President shall give assent to the Bill, after which it becomes a Constitutional Amendment Act.

Three Types of Constitutional Amendments

Type	Majority Required	Examples
Simple Majority	Simple majority of members present and voting	Creation of new States, change in State boundaries, admission of new States and matters outside Article 368.
Special Majority	Majority of the total membership of each House and not less than two-thirds of members present and voting	Fundamental Rights, Directive Principles, Union Judiciary and most constitutional provisions.
Special Majority + State Ratification	Special Majority in Parliament plus approval by at least one-half of the State Legislatures	Election of the President, distribution of legislative powers, Supreme Court and High Courts, Seventh Schedule, Article 368.

Subjects Requiring State Ratification

• Election of the President (Articles 54 and 55).
• Extent of executive powers of the Union and States.
• Supreme Court and High Courts.
• Distribution of legislative powers between the Union and the States.
• Seventh Schedule (Union, State and Concurrent Lists).
• Representation of States in Parliament.
• Article 368 itself.

Comparison of the Three Types

Feature	Simple Majority	Special Majority	Special Majority + State Ratification
Article 368 Applicable	No	Yes	Yes
State Approval Required	No	No	Yes
Difficulty Level	Easy	Moderate	Highest

Important Facts for UPSC

• A Constitutional Amendment Bill cannot be introduced in a State Legislature.
• There is no provision for a joint sitting of Parliament if the two Houses disagree on a Constitutional Amendment Bill.
• The President cannot return a Constitution Amendment Bill for reconsideration after it has been duly passed by Parliament.
• Article 368 provides the procedure, but not every constitutional amendment is made under Article 368; some provisions are amended by a simple majority.

UPSC Examination Tip

Candidates should clearly distinguish between amendments requiring a Simple Majority, a Special Majority, and a Special Majority with State Ratification. This is one of the most frequently tested areas in UPSC Prelims and Mains.

Basic Structure Doctrine

The Basic Structure Doctrine is one of the most important constitutional principles in India. It states that although Parliament has wide powers to amend the Constitution under Article 368, it cannot alter or destroy the Constitution's basic structure or essential features.

This doctrine preserves the identity of the Constitution and ensures that constitutional amendments do not undermine democracy, the rule of law or the rights of citizens.

Why was the Doctrine Developed?

• To prevent unlimited amendment powers.
• To protect constitutional supremacy.
• To preserve democracy and federalism.
• To safeguard Fundamental Rights.
• To maintain judicial independence.
• To uphold the rule of law.

Major Elements of the Basic Structure

Basic Feature	Explanation
Supremacy of the Constitution	The Constitution is the supreme law of the land.
Rule of Law	Everyone is equal before the law.
Judicial Review	Courts can examine the constitutional validity of laws.
Separation of Powers	Legislature, Executive and Judiciary perform separate constitutional functions.
Federalism	Division of powers between the Union and the States.
Secularism	Equal respect for all religions.
Democracy	Government based on the will of the people.
Free and Fair Elections	Essential for representative democracy.
Parliamentary System	Executive is accountable to Parliament.
Unity and Integrity of India	Protection of national sovereignty and cohesion.

Landmark Supreme Court Judgments

Case	Year	Importance
Shankari Prasad v. Union of India	1951	Held that Parliament could amend Fundamental Rights under Article 368.
Sajjan Singh v. State of Rajasthan	1965	Reaffirmed Parliament's power to amend Fundamental Rights.
I.C. Golaknath v. State of Punjab	1967	Held that Parliament could not amend Fundamental Rights.
Kesavananda Bharati v. State of Kerala	1973	Established the Basic Structure Doctrine. Parliament can amend the Constitution but cannot destroy its basic structure.
Indira Nehru Gandhi v. Raj Narain	1975	Declared free and fair elections to be part of the Basic Structure.
Minerva Mills v. Union of India	1980	Held that limited amending power itself is part of the Basic Structure and emphasised harmony between Fundamental Rights and Directive Principles.

I.R. Coelho v. State of Tamil Nadu	2007	Held that laws placed in the Ninth Schedule after 24 April 1973 are subject to judicial review if they violate the Basic Structure.

Flexibility vs Rigidity of the Indian Constitution

The Constitution of India is neither completely rigid nor completely flexible. It combines both features to ensure stability while allowing reforms whenever required.

Rigid Features	Flexible Features
Special majority required for major amendments.	Several provisions can be amended by a simple majority.
Some amendments require State ratification.	Parliament can amend many provisions without State approval.
Basic Structure cannot be altered.	Administrative and procedural provisions can be changed more easily.

Advantages of the Amendment Process

• Allows peaceful constitutional evolution.
• Responds to changing social and economic conditions.
• Protects democratic governance.
• Maintains balance between continuity and reform.
• Strengthens cooperative federalism.
• Ensures constitutional adaptability without replacing the Constitution.

Criticisms

• Federal concerns may arise in amendments affecting State powers.

Contemporary Relevance

• Electoral reforms.
• Judicial reforms.
• Strengthening local self-government.

Q. Why can't Parliament amend the Basic Structure of the Constitution?

Model Answer: The Supreme Court, in the Kesavananda Bharati case (1973), held that although Parliament has broad powers under Article 368, it cannot alter or destroy the Constitution's Basic Structure. This doctrine preserves constitutional supremacy, democracy, the rule of law, judicial review and other essential features.
