An amnesty is a treaty signed by a sovereign state that grants the forgiveness for all their crimes to all the inhabitants of the land subjected to a trial.
In Nilfgaard, when a Imperator ends his reign, his successor usually grants the amnesty. According to the Nilfgaardians laws though, the men whose crime consists in a treason againts the state, aren't allowed to receive forgiveness, like it happened to Vysogota of Corvo with the amnesty proclaimed by the Usurper.
Emperor Emhyr var Emreis also planned to grant another amnesty after his marriage with Cirilla of Cintra.
