Constitution of India – The concept of equality before the law and equal protection of the laws emerges from the fundamental right expressed in Article 14 of the Constitution. Equality is a definite concept. The concept of equality has an inherent limitation arising from the very nature of the constitutional guarantee. Those who are similarly circumstanced are entitled to an equal treatment. Equality is amongst equals. Classification is therefore to be founded on substantial differences which distinguish persons grouped together from those left out of the groups and such differential attributes must bear in just and rational relation to the object sought to be achieved. In a given case Article 14 of the Constitution may permit a valid classification. However, a classification to be followed must necessarily satisfy two tests. Firstly, the distinguishing rationale has to be based on a just objective and secondly, the choice of differentiating one set of persons from another must have a reasonable nexus to the objects sought to be achieved.
