It is apposite to refer the relevant Articles which give power to the President of India and the Governor to grant pardons and to suspend, remit or commute sentences in certain cases. They are as follows :

“Article 72. Power of President to grant pardons, etc. and to suspend, remit or commute sentences in certain cases – (1) The President shall have the power to grant pardons, reprieves, respites or remissions of punishment or to suspend, remit or commute the sentence of any person convicted of any offence –

(a) in all cases where the punishment or sentence is by a Court Martial;

(b) in all cases where the punishment or sentence is for an offence against any law relating to a matter to which the executive power of the Union extends;

(c) in all cases where the sentence is a sentence of death.

(2) Nothing in sub-clause (a) of clause (1) shall affect the power conferred by law on any officer of the Armed Forces of the Union to suspend, remit or commute a sentence passed by a Court martial.

(3) Nothing in sub-clause of clause (1) shall affect the power to suspend, remit or commute a sentence of death exercisable by the Governor of a State, under any law for the time being in force.”

Article 161. Power of Governor to grant pardons, etc. and to suspend, remit or commute sentences in certain cases – The Governor of a State shall have the power to grant pardons, reprieves, respites or remissions of punishment or to suspend, remit or commute the sentence of any person convicted of any offence against any law relating to a matter to which the executive power of the State extends.”

The memoir and scope of Article 72/161 of the Constitution was extensively considered in Kehar Singh v. Union of India & Anr., (1989)1 SCC 204 in the following words :

“7. The Constitution of India, in keeping with modern constitutional practice, is a constitutive document, fundamental to the governance of the country, whereby, according to accepted political theory, the people of India have provided a constitutional polity consisting of certain primary organs, institutions and functionaries to exercise the powers provided in the Constitution. All power belongs to the people, and it is entrusted by them to specified institutions and functionaries with the intention of working out, maintaining and operating a constitutional order. The Preambular statement of the Constitution begins with the significant recital :

We, the people of India, having solemnly resolved to constitute India into a Sovereign Socialist Secular Democratic Republic… do hereby adopt, enact and give to ourselves this Constitution.

To any civilised society, there can be no attributes more important than the life and personal liberty of its members. That is evident from the paramount position given by the courts to Article 21 of the Constitution. These twin attributes enjoy a fundamental ascendancy over all other attributes of the political and social order, and consequently, the Legislature, the Executive and the Judiciary are more sensitive to them than to the other attributes of daily existence. The deprivation of personal liberty and the threat of the deprivation of life by the action of the State is in most civilised societies regarded seriously and, recourse, either under express constitutional provision or through legislative enactment is provided to the judicial organ. 

But, the fallibility of human judgment being undeniable even in the most trained mind, a mind resourced by a harvest of experience, it has been considered appropriate that in the matter of life and personal liberty, the protection should be extended by entrusting power further to some high authority to scrutinise the validity of the threatened denial of life or the threatened or continued denial of personal liberty. The power so entrusted is a power belonging to the people and reposed in the highest dignitary of the State. 

In England, the power is regarded as the royal prerogative of pardon exercised by the Sovereign, generally through the Home Secretary. It is a power which is capable of exercise on a variety of grounds, for reasons of State as well as the desire to safeguard against judicial error. It is an act of grace issuing from the Sovereign. In the United States, however, after the founding of the Republic, a pardon by the President has been regarded not as a private act of grace but as a part of the constitutional scheme.

In an opinion, remarkable for its erudition and clarity, Mr Justice Holmes, speaking for the Court in W.I. Biddle v. Vuco Perovich, 71 L Ed 1161) enunciated this view, and it has since been affirmed in other decisions. The power to pardon is a part of the constitutional scheme, and we have no doubt, in our mind, that it should be so treated also in the Indian Republic. It has been reposed by the people through the Constitution in the Head of the State, and enjoys high status. It is a constitutional responsibility of great significance, to be exercised when occasion arises in accordance with the discretion contemplated by the context. It is not denied, and indeed it has been repeatedly affirmed in the course of argument by learned Counsel, Shri Ram Jethmalani and Shri Shanti Bhushan, appearing for the Petitioner that the power to pardon rests on the advice tendered by the Executive to the President, who subject to the provisions of Article 74(1) of the Constitution, must act in accordance with such advice…..” 

In that case, the Constitution Bench also considered whether the President can, in exercise of the power under Article 72 of the Constitution, scrutinise the evidence on record and come to a different conclusion than the one arrived at by the Court and held as under :

“10. We are of the view that it is open to the President in the exercise of the power vested in him by Article 72 of the Constitution to scrutinise the evidence on the record of the criminal case and come to a different conclusion from that recorded by the court in regard to the guilt of, and sentence imposed on, the accused. In doing so, the President does not amend or modify or supersede the judicial record. The judicial record remains intact, and undisturbed. The President acts in a wholly different plane from that in which the Court acted. He acts under a constitutional power, the nature of which is entirely different from the judicial power and cannot be regarded as an extension of it. and this is so, notwithstanding that the practical effect of the Presidential act is to remove the stigma of guilt from the accused or to remit the sentence imposed on him….

The legal effect of a pardon is wholly different from a judicial supersession of the original sentence. It is the nature of the power which is determinative….

It is apparent that the power under Article 72 entitles the President to examine the record of evidence of the criminal case and to determine for himself whether the case is one deserving the grant of the relief falling within that power. We are of opinion that the President is entitled to go into the merits of the case notwithstanding that it has been judicially concluded by the consideration given to it by this Court.

16. …the power under Article 72 is of the widest amplitude, can contemplate a myriad kinds and categories of cases with facts and situations varying from case to case, in which the merits and reasons of State may be profoundly assisted by prevailing occasion and passing time. and it is of great significance that the function itself enjoys high status in the constitutional scheme.”

Both Articles 72 and 161 repose the power of the people in the highest dignitaries, i.e., the President or the Governor of a State, as the case may be, and there are no words of limitation indicated in either of the two Articles. The President or the Governor, as the case may be, in exercise of power under Article 72/161 respectively, may examine the evidence afresh and this exercise of power is clearly independent of the judiciary. The Court, in numerous instances, clarified that the executive is not sitting as a court of appeal rather the power of President/Governor to grant remission of sentence is an act of grace and humanity in appropriate cases, i.e., distinct, absolute and unfettered in its nature.
