The power to pardon is an essential sovereign function, allowing the Head of State to grant clemency and show mercy, in the interest of justice, humanity, or public welfare.
Difference
However, there are a few similarities
Preemptive Pardons
Pardons granted before conviction or even before formal charges are filed, protecting from future prosecution.
Eg- President Gerald Ford’s 1974 pardon of Richard Nixon in the Watergate scandal.
While the power to pardon is vital as a safety valve of justice, it must be exercised with restraint, transparency, and caution.
