Chapter 8: Amendment and Basic Structure
Chapter TestAmendment and Basic Structure (Article 368)
The Indian Constitution balances rigidity and flexibility. While Parliament has wide powers to amend the Constitution under Article 368, the Supreme Court in Kesavananda Bharati (1973) ruled that the 'Basic Structure' cannot be altered. This ensures adaptability without compromising core constitutional principles.

Amendment Procedure – Criticism and Key Amendments
The Indian Constitution provides flexibility and rigidity through Article 368. While it allows amendments to adapt to changing times, the procedure faces criticism for Parliament’s dominance, limited state role, and similarity to ordinary law-making. Key amendments have addressed retirement age, reservations, defections, Panchayati Raj, and women’s representation.
