Article 368: The Amendment Power

Text and Context

Article 368(1):

“Parliament may, in exercise of its constituent power, amend by way of addition, variation or repeal any provision of this Constitution…”

Key words:

  • Parliament” — only Parliament, not state legislatures (except for some provisions)
  • Constituent power” — different from ordinary legislative power
  • Addition, variation or repeal” — any change permitted

Amendment Procedure (Article 368(2))

Step 1: Bill introduced in either House (Lok Sabha or Rajya Sabha) Step 2: Must be passed by 2/3 majority of present and voting Step 3: If Rajya Sabha passes different version → Joint Sitting (not required — but bill must be same) Step 4: President’s assent — President shall give (not “may give”)

  • Cannot withhold — must sign within 3 months
  • If not signed → becomes law automatically (deemed assent after 3 months)

Limitations on Amendment Power

Kesavananda Bharati (1973):

“The power under Article 368 does not extend to altering the basic structure of the Constitution”

What is Basic Structure? The Court identified these as potentially basic (not exhaustive):

  1. Supremacy of Constitution
  2. Republican and democratic form of government
  3. Secularism and freedom of conscience
  4. Federal structure
  5. Separation of powers
  6. Individual freedom and dignity

Post-1973 additions (by later cases):

  • Free and fair elections (SC, 2019)
  • Right to privacy (2017)
  • Independent judicial appointments (collegium system, 2015)
  • Chartered accountancy independence (2019)

Classification of Amendments

Type 1: Simple Majority Amendments

Procedure: Passed by simple majority of Parliament present and voting Examples:

  • New states (Article 2 — e.g., Andhra Pradesh)
  • Creation of new Union Territories (Article 3)
  • Name changes of states (Article 3)

Article 3 (Important for BPSC):

  • Parliament can create new states and alter boundaries by simple majority
  • No state consent required — but must have President’s recommendation
  • Governor consultation required for new states

Type 2: Special Majority + President’s Assent

Procedure: Passed by 2/3 of members present and voting in each House No state ratification required Examples (most amendments):

  • Most provisions including FR (Part III)
  • DPSP (Part IV)
  • Directive Principles
  • Federal structure

42nd Amendment (1976): Added Socialist, Secular, Fundamental Duties — special majority in both Houses

Type 3: Special Majority + State Ratification

Procedure: Passed by 2/3 in Parliament + Ratified by 50% states (assemblies) Examples:

  • Article 54 (President’s election — changes to electoral college)
  • Article 55 (President’s election — value of votes)
  • Article 73 (Executive power of Union)
  • Article 162 (Executive power of states)
  • Third Schedule (Oath of office)
  • Fifth Schedule (Tribal areas)
  • Sixth Schedule (NE regions, tribal self-governance)
  • Eleventh Schedule (Panchayati Raj subjects)
  • Article 368 itself (cannot be amended to remove basic structure doctrine)

Important: State ratification is required for changes affecting federal structure.

Content:

  • Added Ninth Schedule (protected land reform laws from judicial review)
  • Added Article 31A (immunity for laws implementing DPSP)

Significance: Attempt to overturn Golak Nath (1967) decision

The 25th Amendment (1971)

  • Created hierarchy: DPSP > other laws (but FR remained supreme)
  • Challenge: Does this create a “law above Constitution”? — Court later examined in Minerva Mills

Landmark Cases on Amendment Power

Shankari Prasad v. Union of India (1951)

Issue: Can Parliament amend Fundamental Rights under Article 368?

7-judge bench held:

  • Parliament has absolute power to amend any provision including Part III
  • “Amendment” is not “law” under Article 13
  • Upheld 1st Amendment (land reforms in 9th Schedule)

First view supporting unlimited amendment power.

Sajjan Singh v. State of Rajasthan (1965)

5-judge bench upheld Shankari Prasad:

  • Article 368 gives unlimited power to amend any provision
  • Criticism: Too short reasoning — just followed precedent without analysis

Golak Nath v. State of Punjab (1967)

11-judge benchOverruled earlier decisions:

Held:

  • Article 368 does not allow amendment of Fundamental Rights
  • Transcendental immunity” — FR are above parliamentary power
  • Parliament cannot touch Part III (Fundamental Rights)

Reasoning: FR are part of “basic structure” — can’t be amended (anticipating Kesavananda)

Impact:

  • 42nd Amendment (1976) attempted to overturn this — but this came after Kesavananda
  • Unable to implement land ceiling reforms (challenged by states)
  • Created judicial logjam — courts struck down many laws

Kesavananda Bharati v. State of Kerala (1973) — Most Important

Background: 13-judge bench (largest in Indian history)

Facts: State of Kerala imposed ceiling on property — challenged under Article 31C (DPSP laws)

Held (per Justice Sikri, majority):

“The power of amendment under Article 368 is limited — Parliament cannot alter the basic structure of the Constitution”

What is Basic Structure? The majority identified:

  1. Supremacy of Constitution
  2. Republican and democratic form of government
  3. Secularism
  4. Federalism
  5. Separation of powers
  6. Individual freedom

Key reasoning:

  • Constitution is supreme — not Parliament
  • Amendment power is a constituent power — but it’s not unlimited
  • If unlimited, Parliament could destroy FR and democracy — would be self-contradictory
  • Basic structure is like an “immovable essence” — cannot be altered

Justice Shelat (concurring): “Fundamental Rights and DPSP together form the core of the Constitution”

Dissent: Justice Khanna — said amendment power is limited but basic structure is a vague concept

Result:

  • Overruled Golak Nath on unlimited power
  • Upheld Shankari Prasad that some amendments are valid
  • 42nd Amendment later partly struck down in Minerva Mills

Minerva Mills v. Union of India (1980)

Issue: 42nd Amendment tried to give Parliament unlimited amendment power

Article 368(4) added by 42nd Amendment:

“There shall be no limitation on the constituent power of Parliament”

55th Amendment (1974):

  • Added Article 31C (as per 25th Amendment)
  • Extended protection to any law implementing DPSP (not just Article 39(b)/(c))

Held (per Justice Bhagwati):

Limited amending power is itself a basic feature — cannot be removed”

Key holdings:

  1. Article 368(4) is unconstitutional — because unlimited power destroys basic structure
  2. Extended Article 31C is also invalid — because it makes DPSP superior to FR
  3. Concurrence with Kesavananda: Basic Structure Doctrine is correct

Result:

  • 42nd Amendment partially struck down
  • 55th Amendment partially struck down
  • 42nd Amendment other provisions (Socialist, Secular) upheld — considered valid basic features

Waman Rao v. Union of India (1981)

Issue: Are amendments made after Kesavananda (post-1973) valid?

Held:

  • All amendments passed before 24 April 1973 (date of Kesavananda judgment) are valid (including 1st to 17th Amendments)
  • All amendments passed after 24 April 1973 are subject to basic structure review

Importance: 24th Amendment onward — need to check basic structure compliance

Indira Gandhi v. Raj Narain (1975)

42nd Amendment challenged:

  • National Emergency declared (1975-77)
  • 42nd Amendment passed during Emergency

Held: 42nd Amendment is valid — cannot challenge an amendment on basis of it being passed during Emergency

  • Court refused to examine the legislative process — said proper procedure followed

Supreme Court Advocates-on-Record v. Union of India (2015) — NJAC Case

Issue: 99th Amendment (2014) created NJAC to replace Collegium system

Held: NJAC is unconstitutional — because:

  • Collegium system is part of basic structure (judicial independence)
  • Political involvement in judicial appointments violates separation of powers
  • 99th Amendment Act is invalid

Note: 99th Amendment Act would have removed power from judiciary — basic structure violation
