The Supreme Court has explicitly held that Constitutional Morality is part of the 'Basic Structure' of the Constitution that cannot be amended even by Parliament.

Constitutional Morality and basic structure: (a) While Constitutional Morality is a guiding principle in judicial interpretation (Navtej Singh Johar, Puttaswamy), the Supreme Court has NOT explicitly declared it part of 'Basic Structure' (Kesavananda Bharati doctrine), (b) Basic Structure includes: supremacy of Constitution, republican/democratic form, secularism, federalism, separation of powers, judicial review, rule of law, individual dignity — many derived from Constitutional Morality values, (c) Practical effect: Constitutional Morality operationalizes basic structure values; guides interpretation but remains judicial interpretive tool, not formally enumerated basic feature, (d) Implication: Parliament cannot amend Constitution to destroy basic structure values (which include dignity, equality, secularism); Constitutional Morality helps identify these values. Illustrates nuanced constitutional doctrine: interpretive principles vs. formally enumerated limits.
