This article is about time limitation in criminal law. It is straightly linked to the repressive function of the criminal law. So, as a result of outflow of long-lasting periods of time, punishment becomes useless. General deterrence cannot achieve its main purposes because social indignation will be sufficiently decreased. Everything is much more simpler – people will forget about the harm, inflicted by a certain crime. More than that, when time is lost, it is harder to collect proof of guiltiness; sometimes it looses its legal value. Some scientific methods are applied during the explanation and examination of this problem. At the same time, attempts ar made to solve some legal problems. Thus, there have been analyzed the actual and former penal legislation of Romania in order to establish the notion and importance of limitation of criminal liability in the Criminal law. There have been suggested several points of view and useful conclusions which are necessary to be taken into consideration when a penal case of “limitation” is examined.
