The main objective and purpose of the Act are found in the Preamble of the statute. It contains the recitals showing the reason for enactment of the Act. If the language of the Act is clear the preamble must be ignored.
Example: The preamble of Indian Penal Code, 1860 reads: Whereas it is expedient to provide a general Penal Code for India.
Like the Long Tile, the Preamble of a statute is a part of the enactment and can legitimately be used for construing it. However, the Preamble does not override the plain provision of the Act but if the wording of the statute gives rise to doubts as to its proper construction, e.g. where the words or phrase has more than one meaning and a doubt arises as to which of the two meanings are intended in the Act, the Preamble can and ought to be referred to in order to arrive at the proper construction.
In short, the Preamble to an Act discloses the primary intention of the legislature but can only be brought in as an aid to construction if the language of the statute is not clear. However, it cannot override the provisions of the enactment.
