others similarly situated for the purpose of being specially subjected to discriminating and hostile legislation, it does not insist on an <abstract symmetry= in the sense that every piece of legislation must have universal application. All persons are not, by nature, attainment or circumstances, equal and the varying needs of different classes of persons often require separate treatment and, therefore, the protecting clause has been construed as a guarantee against discrimination amongst equals only and not as taking away from the State the power to classify persons for the purpose of legislation. This classification may be on different bases. It may be geographical or according to objects or occupations or the like. Mere classification, however, is not enough to get over the inhibition of the article. The classification must not be arbitrary but must be rational, that is to say, it must not only be based on some qualities or characteristics which are to be found in all the persons grouped together and not in others who are left out but those qualities or characteristics must have a reasonable relation to the object of the legislation. In order to pass the test, two conditions must be fulfilled, namely, (1) that the classification must be founded on an intelligible differentia which distinguishes those that are grouped together from others, and (2) that that differentia must have a rational relation to the object sought to be achieved by the Act. The differentia which is the basis of the classification and the object of the Act are distinct things and what is necessary is that there must be a nexus between them. In short, while the article forbids class legislation in the sense of making improper discrimination by conferring privileges or imposing liabilities upon persons arbitrarily selected out of a large number of other persons similarly situated in relation to the privileges sought to be conferred or the liability proposed to be imposed, it does not forbid classification for the purpose of legislation, provided such classification is not arbitrary in the sense I have just explained. The doctrine, as expounded by this Court in the two cases I have mentioned, leaves a considerable latitude to the Court in the matter of the application of Article 14 and consequently has the merit of flexibility.
