Abstract
The article concerns the issue of access of the suspect and their counsel to the preparatory files in the course of the pre-trial detention procedure . The author analyzes the legislative changes that have taken place in this area in recent years, comparing the discussed regulations with constitutional and international norms. The study also emphasizes the need to respect fully the provisions of Directive 2012/13 / EU of the European Parliament and of the Council of 22 May 2012 on the right to information in criminal proceedings, and proposed a method of resolving the conflict of national regulations with EU laws in that respect.
