The Preamble is not a part of the Constitution. It does not have any legal force. Still it has special significance.
The significance of the Preamble is as follows :
- Source of Authority. The Preamble expresses in a very clear language that people are the ultimate source of all authority. It is the people who have adopted and enacted the Constitution; It is the people who have given ‘the Constitution to themselves.’ The words, we the people of India, are very significant.
- Nature of Indian Polity. The Preamble emphasises the fact that India is a Sovereign, Socialist, Secular, Democratic, Republic.
- Symbol of Objectives. The Preamble is the symbol of those objectives which the Constitution makers pledged to attain. The Preamble assures the people of India Justice—Social, Economic and Political.
- Key to the Constitution. The Preamble is the soul and spirit of the Constitution. The Preamble is the mirror of the Constitution. It is a jewel set in the Constitution.
- Guide to the Government. The Preamble to the Constitution provides guidelines to the government of the day.
- Guidelines to the Judiciary. Whenever a Court of Justice has to explain some articles of the Constitution then it takes the help of the ideas expressed through the Preamble of the Constitution.
- Yardstick to evaluate the performance of the Government. The Preamble enables the people to assess and evaluate the performance of the government in the light of the objectives laid down in the Preamble. It keeps the government on its toe.
