The constitution of India begins with a preamble which specifies the nature of the Indian state and the objectives it is committed to secure.
The preamble categorically accepts the principle of popular sovereignty. The Preamble begins with the words “we the people” and ends by recording that it is a “self-made adopted and enacted constitution of India.”
The words ‘socialist’, ‘secular’ and ‘Integrity’ were initially not there in the preamble and were added to it by the 42nd Amendment (1976) to the constitution.
The preamble refers to the five cardinal features of India as a state. It declares India to be a sovereign, socialist, secular, democratic republic.
Indian constitution seeks to secure Justice- social, economic and political for all the citizens.
The preamble declares liberty to be the second cardinal objective to be secured by the Indian state. It lists liberty of thought, expression, belief, faith and worship as the objective to be secured to all the people.
The preamble makes equality the third major objective of the constitution. It has been described in terms of two variables: equality of status and equality of opportunity.
Another major objective is to promote among all the people fraternity i.e. a feeling of spiritual, psychological unity and brotherhood. It is designed to secure dignity of the individual and unity and integrity of the nation.
The constitution of India is an adopted, enacted and self-made constitution. It was adopted and enacted by the constituent assembly as the elected representative body acting on behalf of the people of India.
Supreme Court in its judgement in keshvanandabharati case held that preamble is a part of the constitution. Though it is not enforceable yet it forms a part of the constitution.
