Practice Relating to Rule 159. Amnesty
Under its Amnesty Law of 1985, Uruguay granted amnesty with respect to all political offences and criminal and military offences related thereto committed after 1 January 1962. “Political offences” are defined as those committed directly or indirectly for political motives. The amnesty extends to all persons accused of committing these offences as authors, co-authors or accomplices and accessories, whether or not they have been convicted or tried. Offences committed by police or military personnel, equiparados, and others who have subjected individuals to inhuman, cruel or degrading treatment or detained individuals who subsequently disappeared are excluded, as are offences committed by persons of these categories who acted as accomplices for or covered up those offences. Penalties and sanctions imposed for the amnestied offences were also declared null and void ab initio.

In 1986, Uruguay adopted an Amnesty Law for offences committed between 1984 and 1985 by military and police personnel for political motives or in the course of discharging their functions, and for offences committed on orders received during the “de facto period” when a situation of internal violence prevailed.
