In Argentina, the term "impunity laws" (Spanish: Leyes de impunidad) refers to two laws and a series of presidential decrees enacted between 1986 and 1990, which prevented the prosecution or execution of convictions against perpetrators of crimes against humanity during the state terrorism carried out by the Military Junta in the 1976 civil-military coup d'état, which governed from 1976 to 1983. On May 3, 2017, the Supreme Court issued a ruling that allows the sentences of persons found guilty of crimes against humanity to be significantly reduced, by application of the so-called "two for one".
