what is the importance of Preamble
The Preamble to a Constitution embodies the fundamental values and the philosophy, on which the Constitution is based, and the aims and objectives, which the founding fathers of the Constitution enjoined the polity to strive to achieve. The importance and utility of the Preamble has been pointed out in several decisions of the Supreme Court of India.
Though, by itself, it is not enforceable in Court of Law , the Preamble to a written Constitution states the objects which the constitution seeks to establish and promote and also aids the legal interpretation of the Constitution where the language is found to be ambiguous . The Preamble to our Constitution serves, two purposes:
(a) It indicates the source from which the constitution derives its authority:
(b) It also states the objects which the constitution seeks to establish and promote.
