Both the President (under Article 72) and the Governor (under Article 161) of India possess the power to grant pardons, reprieves, respites, remissions, suspend, or commute sentences. However, there are crucial differences in the scope and application of these powers, reflecting the distinct jurisdictions of the Union and State governments.

Firstly, the scope of the President's pardoning power is significantly wider than that of the Governor. The President can grant pardon in all cases where the punishment or sentence is for an offense against any law relating to a matter to which the Union's executive power extends. Crucially, the President's power extends to sentences awarded by court-martial (military courts), a power not available to the Governor. Furthermore, the President is the only authority who can pardon a death sentence in all cases. While a Governor can suspend, remit, or commute a death sentence, they cannot grant a full pardon that completely absolves the convict of the death penalty. The power to pardon a death sentence rests exclusively with the President.

Secondly, the jurisdictional reach differs. The President's power under Article 72 applies to offenses against laws made by the Union Parliament, whereas the Governor's power under Article 161 applies to offenses against laws relating to a matter to which the executive power of the state extends, i.e., state laws. This means that if an offense falls under the Union List or Concurrent List (where Parliament has legislated), the President's power is applicable. If it falls under the State List, the Governor's power is applicable. In cases where both Union and State laws apply, the President's power generally takes precedence, especially concerning death sentences or military justice.

In essence, while both function as a 'mercy' power, the President's authority is more comprehensive, encompassing military justice and the ultimate power over death sentences, reflecting the President's position as the head of the Union and the supreme commander of the armed forces, whereas the Governor's power is limited to offenses against state laws and does not extend to military courts or the final pardon of capital punishment.
