Implementing EU Sanctions Through Criminal Law: Serious Negligence as a New Form of Culpability in the Slovak Republic

The enforcement of European Union restrictive measures increasingly relies on criminal law at national level, particularly in response to serious and systematic violations that cannot be effectively addressed through administrative sanctions alone. Directive (EU) 2024/1226 requires Member States to ensure effective, proportionate, and dissuasive criminal penalties for breaches of EU sanctions, including, in defined cases, conduct committed with serious negligence. This article examines the introduction of serious negligence as a new statutory form of culpability in the Slovak Republic, adopted through Act No. 157/2025 Coll. as part of the transposition of Union law. The analysis is based on a doctrinal examination of Slovak criminal law, legislative materials, and relevant EU legal instruments, complemented by a comparative overview of selected Member States. The article demonstrates that the Slovak legislator introduced serious negligence (Slovak: hrubá nedbanlivosť) as a qualified form of negligence in a cautious and narrowly circumscribed manner, limiting its application to a specific offence relating to the breach of a restrictive measure. While this approach strengthens the effectiveness of EU sanction enforcement, it also raises interpretative and practical challenges, particularly in distinguishing serious negligence from ordinary negligence and indirect intent. The article concludes that the Slovak model reflects a balanced attempt to comply with Union obligations while preserving the internal coherence and fundamental principles of national criminal law, with its long-term impact depending on consistent judicial interpretation and restrained application in practice.
