Constitutional Amendment vs Ordinary Law: What Is the Difference? Article 368 & Procedure

In Indian constitutional jurisprudence, a fundamental distinction exists between the constituent power to amend the Constitution and the ordinary legislative power to enact statutory laws. The Constitution of India represents the supreme organic law of the land—the foundational charter establishing the institutional architecture of governance, the separation of powers, and Fundamental Rights. Statutory laws enacted by Parliament or State Legislatures derive their legal validity from this constitutional bedrock. A comprehensive understanding of the procedural, substantive, and judicial boundaries separating an ordinary legislative act from a constitutional amendment is vital for legal scholars and civil service aspirants.

Ordinary laws are enacted by Parliament under Articles 107 and 108 using the legislative powers distributed across the Union, State, and Concurrent Lists of the Seventh Schedule. They require passage by a Simple Majority (a majority of members present and voting) in each House. If a legislative deadlock arises between the Lok Sabha and Rajya Sabha over an ordinary bill, the President can convene a Joint Sitting of both Houses under Article 108. Additionally, under Article 111, the President possesses discretionary options: granting assent, withholding assent, or returning the bill for legislative reconsideration. Most importantly, ordinary laws are subordinate to Article 13(2), which commands that any statutory law inconsistent with or in derogation of Fundamental Rights is void ab initio.

By contrast, a Constitutional Amendment is enacted under Article 368 in Part XX through Parliament's constituent power. A Constitutional Amendment Bill demands a rigorous Special Majority: an absolute majority of the total membership of each House, coupled with a two-thirds majority of members present and voting. Significantly, a Joint Sitting is strictly prohibited under Article 368; each House must pass the amendment independently. Under Article 368(2) (as amended by the 24th Amendment Act, 1971), the President must grant assent and has no power to withhold assent or return the bill. When amending entrenched federal provisions, ratification by at least half of state legislatures is mandatory. Above all, while ordinary laws can be struck down for violating any constitutional provision, constitutional amendments can be struck down only if they violate the "Basic Structure" of the Constitution, a doctrine established by the Supreme Court in the historic Kesavananda Bharati case (1973).

Essential Concepts & Key Facts

High-yield conceptual summaries for competitive exams and rapid revision.

  • An ordinary law is enacted under Parliament's legislative power, while a constitutional amendment is enacted under its constituent power.
  • Ordinary laws are enacted under Articles 107–108; Constitutional amendments are governed by Article 368 in Part XX of the Constitution.
  • An ordinary bill requires only a Simple Majority (more than 50% of members present and voting) to pass each House.
  • A Constitutional Amendment Bill requires a Special Majority: more than 50% of total house membership AND two-thirds of members present and voting.
  • If an amendment affects federal provisions (like judiciary powers or state representation), it must also be ratified by 50% of State Legislatures.
  • State legislative ratification under Article 368 requires only a Simple Majority in each ratifying state legislative assembly.
  • A Joint Sitting of Parliament under Article 108 can resolve deadlocks on ordinary bills, but is strictly prohibited for Constitutional Amendment Bills.
  • Both the Lok Sabha and Rajya Sabha hold equal veto power over Constitutional Amendment Bills; a deadlock permanently defeats the bill.
  • Under Article 111, the President can grant assent, withhold assent, or return an ordinary bill for parliamentary reconsideration.
  • Under Article 368(2), the President has no veto power: the President must grant assent to a duly passed Constitutional Amendment Bill.

  • Article 13(2) declares that ordinary statutory laws violating Fundamental Rights are unconstitutional and void ab initio.

  • In Kesavananda Bharati v. State of Kerala (1973), a 13-judge bench established the landmark Basic Structure Doctrine.
  • The Basic Structure Doctrine holds that Parliament's constituent power under Article 368 cannot alter the core framework of the Constitution.
  • Elements of the Basic Structure include the supremacy of the Constitution, republican democracy, secularism, judicial review, and federalism.
  • Certain constitutional provisions (like creating new states under Article 3 or establishing Legislative Councils under Article 169) are amended by simple majority.
  • Amendments passed by a simple majority outside Article 368 are not deemed to be amendments for the purposes of Article 368.
