Clemency

A pardon is the forgiveness of a crime and the penalty associated with it. It is granted by a sovereign power, such as a monarch or chief of state or a competent church authority. Clemency is an associated term, meaning the lessening of the penalty of the crime without forgiving the crime itself. The act of clemency is a reprieve. Today, pardons and reprieves are granted in many countries when individuals have demonstrated that they have fulfilled their debt to society, or are otherwise deserving (in the opinion of the pardoning official) of a pardon or reprieve. Pardons are sometimes offered to persons who, it is claimed, have been wrongfully convicted. However, accepting such a pardon implicitly constitutes an admission of guilt, so in some cases the offer is refused (cases of wrongful conviction are nowadays more often dealt with by appeal than by pardon).

Clemency is often requested by foreign governments who don't use capital punishment when one of their citizens has been given the death penalty.
