Impact of the European Union on Criminal Law of EU Member States

Reviewed collection of papers of the international scientific conference is the output of the international scientific conference held on 7^th October 2022 within the framework of the project APVV-18-0421 „European Public Prosecutor's Office in Connections of the Constitutional Order of the Slovak Republic as Strengthening of the European Integration through Law“. Unlike other areas of activities of the European Union, the European Union did not begin to enter the area of criminal law and criminal policy until much later. The reason is that the sphere of criminal law has traditionally been associated with the sovereignty of the state, which is why the Member States of the European Union are very slow to allow the European Union into it. The issue of the European Union's influence on the criminal law of its Member States is therefore becoming actual and raises many questions and application problems. In their  papers, the authors address the various problems posed by the European Union's influence in the area of criminal law. Among the scientific problems and issues that the authors paid attention to in their works are the following: reasons for competence of the European Union within the field of criminal law; Impact of the EU legislation on criminal law of EU Member States; proposals to improve existing legislation, whether at European Union or national level, cooperation of the Court of Justice of the European Union and national judges via preliminary proceedings within the field of criminal law; as well as the issue of the European Public Prosecutor's Office.
