Practice Relating to Rule 160. Statutes of Limitation
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, Honduras stated:
War criminals should have the benefit of statutory limitation for humanitarian reasons. Many countries’ constitutions established that principle and made it part of their law … It was … reasonable that when the period of statutory limitation expired [a war criminal] should gain a certain degree of relief. 
Honduras, Statement before the Third Committee of the UN General Assembly, UN Doc. A/C.3/SR.1547, 12 December 1967, § 7.
