The Concept of EqualityÂ
From a positivistic point of view, equality is antithetic to arbitrariness. In fact equality and arbitrariness are sworn enemies; one belongs to the rule of law in a republic while the other, to the whim and caprice of an absolute monarch. Where an act is arbitrary it is implicit in it that it is unequal both according to political logic and constitutional law and is therefore violative of ARTICLE 14, and if it affects any matter relating to public employment, it is also violative of ARTICLE 16. Arts. 14 and 16 strike at arbitrariness in State action an( ensure fairness and equality of treatment. They require that State action must be based on valent relevant principles applicable alike to all similarly situate and it must not be guided by any extraneous or irrelevant considerations because that would be denial of equality. Where the operative reason for State action, as distinguished from motive inducing from the antechamber of the mind, is not legitimate and relevant but is extraneous and outside the area of permissible considerations, it would: amount to mala fide exercise of power and that is hit by Arts. 14 and 16. Mala fide exercise of Power and arbitrariness are different lethal radiations emanating from the same vice: in fact the matter comprehends the former. Both are inhibited by Arts. 14 and 16 It is also necessary to point out that the ambit and reach of Arts. 14 and 16 are not limited to cases where the public servant affected has a right to a post. Even if a public servant is in an officiating position, he can complain of violation of Arts. 14 and 16 if he has been. arbitrarily or unfairly treated or subjected to mala fide exercise of. power by the State machine.  Art 16 embodies the fundamental guarantee that Arts. 14 as there shall be equality of opportunity for all citizens in matters relating to employment or appointment to any office under the State. Though enacted as a distinct and independent fundamental right because of its great importance as a principle ensuring equality of opportunity in public employment which is so vital to the building up of the new classless egalitarian society envisaged in the Constitution, Art 16 is only an instance of the application of the concept of equality enshrined in Art 14. In other words, Art 14 is the genus while Art 16 is a species, Art 16 gives effect to the doctrine of equality in all matters relating to public employment. The basic principle which, therefore, informs both Arts. 14 and 16 is equality and inhibition against discrimination( E. P.
