The power to grant pardon is enshrined in Article 72 of the Constitution of India for the President and Article 161 for the Governor.
This power enables the President or Governor to grant pardons, reprieves, respites, or remissions of punishment, or to suspend, remit, or commute the sentence of any person convicted of any offence.
Though it affects judicial decisions, this is not a judicial function — it is a sovereign and discretionary act performed by the head of the Executive.
Hence, it is classified under Executive powers and is based on principles of justice, humanity, and public welfare.
