An Amnesty law is any legislative, constitutional or executive arrangement that retroactively exempts a select group of people, usually military leaders and government leaders, from criminal liability for the crimes that they committed. More specifically, in the 'age of accountability', amnesty laws have come to be considered as granting impunity for the violation of human rights, including institutional measures that preclude the prosecution for such crimes and reprieve those crimes already convicted, avoiding any form of accountability.
