The question of whether the Preamble could be amended arose in the Kesavananda Bharati Case (1973):
- Amendable with Limitations: The Court held that while the Preamble can be amended under Article 368, such amendments must not alter the Constitution’s “basic structure.”
- 42nd Amendment (1976):
- The only amendment to the Preamble added the terms “Socialist,” “Secular,” and “Integrity.”
- This change reflected the evolving socio-political ideals of the time while adhering to the Constitution’s fundamental principles.
