  • The Preamble is based on Jawaharlal Nehru’s "Objectives Resolution", introduced on December 13, 1946, and adopted on January 22, 1947.
  • The Preamble has been amended ONLY ONCE till date by the 42nd Constitutional Amendment Act, 1976, which added three new words: SOCIALIST, SECULAR, and INTEGRITY.
  • In Kesavananda Bharati (1973), the Supreme Court ruled that the Preamble IS part of the Constitution and can be amended under Article 368 without altering the Basic Structure.
  • The Preamble is non-justiciable (not enforceable in courts of law) and is neither a source of power to the legislature nor a prohibition upon legislative powers.

1. The 4 Core Ingredients of the Preamble

The Preamble reveals four essential dimensions of the Indian Polity: 1. **Source of Authority:** Derives its authority directly from the people of India (*"We, the People of India"*). 2. **Nature of Indian State:** Sovereign, Socialist, Secular, Democratic, Republic. 3. **Objectives of the Constitution:** Justice (Social, Economic, Political), Liberty (Thought, Expression, Belief, Faith, Worship), Equality (Status and Opportunity), and Fraternity (Assuring the dignity of the individual and unity & integrity of the nation). 4. **Date of Adoption:** 26th November 1949.

2. Breakdown of Key Keywords in Sequence

• **Sovereign:** India is neither a dependency nor a dominion of any other nation. It is completely free to conduct its own internal and external affairs. • **Socialist (Added by 42nd CAA 1976):** Indian socialism is 'Democratic Socialism' (mixed economy), not 'Communist Socialism' (state nationalization). • **Secular (Added by 42nd CAA 1976):** India embodies 'Positive Secularism' — giving equal respect and protection to all religions, unlike Western negative secularism. • **Democratic:** Parliamentary democracy with universal adult franchise, rule of law, and independent judiciary. • **Republic:** The head of state (President of India) is always elected indirectly for a fixed term of 5 years; there is no hereditary monarch.

3. Supreme Court Judgments on Preamble Status

• **Berubari Union Case (1960):** The Supreme Court held that the Preamble is NOT a part of the Constitution. • **Kesavananda Bharati Case (1973):** Overruled Berubari Union. The Court held that the Preamble **IS part of the Constitution** and contains the basic elements of the constitutional philosophy. • **LIC of India Case (1995):** Reaffirmed that the Preamble is an integral part of the Constitution.
