CHAPTER 2. Territorial Application of the Criminal Law and Question of its Retroactivity
Article 13. Retroactive Effect of the Criminal Law
(1) The criminal law eliminating criminality of an act, mitigating a sentence or improving condition of a person who committed a crime, is retroactive, i.e. it affects persons who committed a crime before such law came into legal force, including persons who are serving sentence or have already served but have criminal record. From the moment the law eliminating criminality of an act came into legal force, the act committed before its coming into force, is not considered to be criminal.
(2) If a new criminal law mitigates punishability of an act, for which a person is serving his sentence, this sentence is liable to reducing in accordance with the high limit of the sanction of the newly issued criminal law.
(3) The criminal law establishing criminality of an act, aggravating a sentence or adversely affecting a person who committed this act is not retroactive.
