More recently, Lyal S. Sunga has argued that unless truth commissions are set up and conducted according to international human rights law, international criminal law and international humanitarian law, they risk conflicting or undermining criminal prosecutions, whether these prosecutions are supposed to be carried out at the national or international levels. He contends that this risk is particularly pronounced where truth commissions employ amnesties, and especially blanket amnesties to pardon perpetrators of serious crimes. On the other hand, criminal prosecutions should be better tailored to focus on victims and to place events in proper perspective. Sunga therefore proposes ten principles for making truth and national reconciliation commissions fully complementary to criminal prosecutions in a way that conforms fully to international law.
