A more thorough explanation: The prerogative of mercy refers to the discretionary power or authority vested in a head of state or government to grant clemency, pardon, or reprieve to individuals who have been convicted of a crime. This power is typically exercised in cases where there are compelling humanitarian or public interest reasons to mitigate the severity of a sentence or to grant forgiveness.
Example: The prerogative of mercy allows the President to pardon individuals convicted of federal crimes.
