Introduction
The Indian Constitution represents a unique synthesis of flexibility and rigidity, carefully structured to balance adaptability with stability. Unlike constitutions that are either entirely flexible or hyper-rigid, it introduces a graded mechanism of amendment depending on the nature and federal significance of the provision.
1. Procedural Framework: Within vs. Outside Article 368
- Outside Article 368 (Flexible Route): Certain provisions can be amended by a simple majority in Parliament, similar to ordinary legislative procedures. Under Articles 4(2) and 169(3), actions like the reorganization of state boundaries or the creation/abolition of State Legislative Councils are expressly excluded from the formal purview of Article 368.
- Under Article 368 (Rigid Route): Most core constitutional provisions, such as Fundamental Rights and Directive Principles of State Policy, require a special majority (a majority of the total membership of each House and a two-thirds majority of members present and voting).
- Proviso to Article 368 (Hyper-Rigid/Federal Route): Matters impacting federal arrangements (e.g., representation of states in Parliament, distribution of legislative powers, or the amendment power itself) require a special majority plus ratification by at least 50% of state legislatures. For instance, the Uttar Pradesh Legislature ratified the 101st Constitutional Amendment (GST Act) via this federal ratification procedure in May 2017.
2. Comparative Analysis with Modern Constitutions
- United Kingdom: Characterized by complete flexibility. Lacking a codified constitution, the British Parliament can alter constitutional arrangements through ordinary legislation passed by a simple majority.
- United States (Article V): Highly rigid. Amending the US Constitution requires a two-thirds vote in both Houses of Congress (or a convention called by two-thirds of the states) followed by ratification by three-fourths of the states, leading to only 27 amendments in over two centuries.
- Australia (Section 128): Demonstrates democratic rigidity through a required referendum. An amendment requires a 'Double Majority'—an overall national popular majority plus a concurrent majority of voters in a majority of states (at least four out of six states).
- Canada (Constitution Act, 1982): Employs a complex tiered formula, predominantly the '7/50 rule', which mandates the consent of the Federal Parliament alongside resolutions from at least seven provincial legislative assemblies representing at least 50% of the aggregate provincial population for major federal changes.
3. Judicial Check: The Basic Structure Doctrine
While the textual provisions offer varying degrees of flexibility, the Indian Supreme Court in Kesavananda Bharati v. State of Kerala (1973) introduced an absolute judicial check through the Basic Structure Doctrine. By ruling that Parliament cannot alter core tenets such as judicial review, secularism, and federalism, the judiciary embedded a layer of non-negotiable rigidity to preserve constitutional identity.
Conclusion
By blending procedural ease for administrative needs with rigorous safeguards for federal and democratic structures, the Indian Constitution strikes a viable middle path. It circumvents both the fossilization seen in the US system and the institutional vulnerability of the UK model, functioning dynamically as a living document.
