Part III of the Indian Constitution (Articles 12–35) incorporates Fundamental Rights, drawing deep philosophical inspiration from England's Magna Carta (1215), the French Declaration of the Rights of Man (1789), the American Bill of Rights (1791), and the Universal Declaration of Human Rights (UDHR, 1948). During the colonial era, the Nehru Report (1928) and the Karachi Resolution (1931) explicitly demanded these guarantees for independent India.
- Article 12 (Definition of 'State'): Defines against whom Fundamental Rights are enforceable. It includes: (1) Government and Parliament of India, (2) Government and Legislature of each State, (3) All local authorities (Municipalities, Panchayats, District Boards), and (4) Other authorities within India or under the control of the Government of India (statutory corporations like LIC, ONGC, SAIL).
- Article 13 (Laws Inconsistent with Fundamental Rights): Operates as the touchstone of Judicial Review. Article 13(1) states that all pre-constitutional laws violating Part III are void to the extent of inconsistency (Doctrine of Eclipse). Article 13(2) mandates that the State shall not make any post-constitutional law that takes away or abridges Fundamental Rights; any law made in contravention shall be void (Doctrine of Severability).
- Basic Structure Doctrine (Kesavananda Bharati Case, 1973): The Supreme Court ruled that while Parliament can amend Fundamental Rights under Article 368, it cannot abrogate or alter the 'Basic Structure' of the Constitution.
