TY - JOUR AU - Rosin, Kaie PY - 2021/10/13 Y2 - 2024/03/28 TI - The Relationship between EU Law and Fundamental Principles of Estonian Substantive Criminal Law JF - Juridica International JA - JI VL - 30 IS - SE - Articles DO - 10.12697/JI.2021.30.19 UR - https://ojs.utlib.ee/index.php/juridica/article/view/18284 SP - 174-182 AB - Although the EU lacks explicit competence to harmonise national principles of criminal law, there are many ways in which EU law and national criminal law are interconnected on a level deeper than mere minimum standards adopted from directives. The article analyses these intersections between EU law and fundamental principles of Estonian substantive criminal law, explaining how the principles of criminal law recognised and interpreted in the case law of the Court of Justice of the EU and covered by the Charter of Fundamental Rights of the European Union exhibit the capacity to affect fundamental principles of Estonian substantive criminal law. The article focuses on five principles specific to substantive criminal law, which are derived from the fundamental principles of the Estonian Constitution and have equivalents in human-rights law: the principle of legality of criminal law, the principle of retroactive application of the more lenient criminal law, proportionality, <i>ultima ratio</i>, and the principle of individual guilt. The analysis demonstrates that the relationship between EU law and the various principles of substantive criminal law is not uniform because the principles of substantive criminal law are not developed evenly at European Union level.
