In Maru Ram v. Union of India reported in (1981) 1 SCC 107 the Court speaking eruditely through the inimitable Krishna Iyer, J., observed that all public power including constitutional powers of pardon, commutation and release under Articles 72 and 161 of the Constitution respectively, cannot run riot or be exercisable irrationally or arbitrarily.

Any action under these provisions must be informed by the finer canons of constitutionalism. In his words, “the rule of law, under our constitutional order, transforms all public power into responsible, responsive, regulated exercise informed by high purposes and geared to people’s welfare”. It held that all the powers entrusted by the Constitution must, in its exercise, eschew any form of arbitrariness and stem from an intelligible and well-reasoned criterion that is predicated on an earnest purpose. It further categorically held that – “while constitutional power is beyond challenge, its actual exercise may still be vulnerable” – to judicial review.

In the last, Krishna Iyer, J., further cautioned that such power ought not to be vulgarized or abused by personal vanity and the notions of those exercising such powers. The relevant observations read as under:

“62. An issue of deeper import demands our consideration at this stage of the discussion. Wide as the power of pardon, commutation and release (Articles 72 and 161) is, it cannot run riot; for no legal power can run unruly like John Gilpin on the horse but must keep sensibly to a steady course. Here, we come upon the second constitutional fundamental which underlies the submissions of counsel. It is that all public power, including constitutional power, shall never be exercisable arbitrarily or mala fide and, ordinarily, guidelines for fair and equal execution are guarantors of the valid play of power. We proceed on the basis that these axioms are valid in our constitutional order.

63. The jurisprudence of constitutionally canalised power as spelt out in the second proposition also did not meet with serious resistance from the learned Solicitor-General and, if we may say so rightly. Article 14 is an expression of the egalitarian spirit of the Constitution and is a clear pointer that arbitrariness is anathema under our system. It necessarily follows that the power to pardon, grant remission and commutation, being of the greatest moment for the liberty of the citizen, cannot be a law unto itself but must be informed by the finer canons of constitutionalism. […] It is the pride of our constitutional order that all power, whatever its source, must, in its exercise, anathematise arbitrariness and obey standards and guidelines intelligible and intelligent and integrated with the manifest purpose of the power. From this angle even the power to pardon, commute or remit is subject to the wholesome creed that guidelines should govern the exercise even of presidential power.

65. Pardon, using this expression in the amplest connotation, ordains fair exercise, as we have indicated above. Political vendetta or party favouritism cannot but be interlopers in this area. The order which is the product of extraneous or mala fide factors will vitiate the exercise. While constitutional power is beyond challenge, its actual exercise may still be vulnerable. Likewise, capricious criteria will void the exercise. For example, if the Chief Minister of a State releases everyone in the prisons in his State on his birthday or because a son has been born to him, it will be an outrage on the Constitution to let such madness survive. […] Push this logic a little further and the absurdity will be obvious.

No constitutional power can be vulgarised by personal vanity of men in authority. Likewise, if an opposition leader is sentenced, but the circumstances cry for remission such as that he is suffering from cancer or that his wife is terminally ill or that he has completely reformed himself, the power of remission under Articles 72/161 may ordinarily be exercised and a refusal may be wrong-headed. If, on the other hand, a brutal murderer, bloodthirsty in his massacre, has been sentenced by a court with strong observations about his bestiality, it may be arrogant and irrelevant abuse of power to remit his entire life sentence the very next day after the conviction merely because he has joined the party in power or is a close relation of a political high-up.
