I.R. Coelho (dead) by LRs v. State of Tamil Nadu AIR 2007 SC 861,

The State is to deny no one equality before the law.... Economic growth and social equity are the two pillars of our Constitution which are linked to the right of an individual (right to equal opportunity), rather than in the abstract.... Equality, rule of law, judicial review and separation of powers form parts of the basic structure of the Constitution. Each of these concepts are intimately connected. There can be no rule of law, if there is no equality before the law. These would be meaningless if the violation was not subject to the judicial review.
