Practice Relating to Rule 160. Statutes of Limitation
Uruguay’s Law on Cooperation with the ICC (2006) states: “The crimes and punishments set out in Titles I to III of Part II of the present law [i.e. genocide, crimes against humanity and war crimes] are not subject to statutes of limitation.” 
Uruguay, Law on Cooperation with the ICC, 2006, Article 7.
In 1967, during a debate in the Third Committee of the UN General Assembly on the question of the punishment of war criminals and of persons who have committed crimes against humanity, the representative of Uruguay stated:
Under Uruguayan legislation, statutory limitation would be applied to all crimes, the period of limitation depending on the severity of the punishment. He recognized, however, that in the present instance, since international law prevailed over domestic law, war crimes and crimes against humanity could be excluded from the range of applicability of the rules regarding statutory limitation, or at least that the periods of limitation could be prolonged in the case of such crimes.
