In which situation can a pardon not be exercised?

A pardon is a legal forgiveness for an offense, which typically absolves the individual from the consequences of their conviction. It is important to understand the timing of when a pardon can be granted, as this highlights the legal process involved in both trial and sentencing.

The correct answer, which indicates that a pardon cannot be exercised before a trial, is grounded in the nature of legal proceedings. At this stage, the individual has not yet been found guilty of any crime, and therefore there is no conviction or punishment that requires forgiveness. A pardon specifically addresses consequences that arise after a formal legal decision has been made regarding guilt.

This means that, until the trial concludes and a conviction is rendered, the individual is not in a position to receive a pardon, as there is nothing to pardon. The criminal justice system operates on the principle of due process; until the court has made a determination of guilt or innocence, there is no basis for pardon.

In contrast, a pardon can be exercised after a conviction or while an individual is serving their sentence, as in those cases, the legal consequences have been established, and the individual may be deemed eligible for clemency or forgiveness.
