It is a preface or the introduction to the Constitution. It is not an integral part of constitution. The interpretation of constitution is based on the spirit of Preamble.
The ‘Objective Resolution’, proposed by Pandit Nehru and passed by the Constituent Assembly, ultimately became the Preamble.
The Preamble States :
“We, the People of India, have solemnly resolved to constitute India into a Sovereign Socialist Secular Democratic Republic and to secure to all citizens:
Justice social, economic and political; Liberty of thought, expression, belief, faith and worship; Equality of status and of opportunity; and to promote among them all Fraternity assuring the dignity of the individual and the unity and integrity of the Nation; in Our Constituent Assembly, this twenty – sixth day of November, 1949, do Hereby Adopt, Enact and Give to Ourselves this Constitution.”
The idea of preamble was borrowed from the constitution of USA. The words ‘Socialist’, ‘Secular’ And ‘Integrity’ were added by the 42nd Amendment in 1976.
Sovereign means free to follow internal and external policies. Socialist means no concentration of power and money. Secular means no particular religion.
Democratic means Elected representatives. Republic means no room for hereditary ruler or monarch. Preamble is not justiciable.
