This article is about time limitation in international criminal law. It is straightly linked to the repressive function of criminal law. Time represents one of the basic and fundamental dimensions within the framework of which human activity is developing. Any type of person’s behavior takes place inside a period of time. There are established both the beginning, and the end of the action. Nothing can avoid the influence of time. More than it, a period of time can cure sufferings of people whom harm was inflicted. Pain and discords can disappear during a certain period of time. So, we are going to note that criminal events also take place in a period of time. Also, by means of time age of criminal responsibility can be established. So, as a result of outflow of long-lasting period of time, punishment becomes useless. General deterrence cannot achieve its main purposes because social indignation will be sufficiently decreased. All much more simply – people will forget about harm, inflicted by a certain crime. More than that, when time is lost, it is harder to collect proof of guiltiness; sometimes it loses its legal value. Some scientific methods are applied during the explanation and examination of this problem. At the same time, an attempt has been made to solve some legal problems. There were suggested several points of view and useful conclusions which are necessary to be taken into consideration when a penal case of “limitation” is examined.
