Abstract
The coming into force of the amendments to the Penal Code and certain other statutes enacted on 20 February 2015 gives rise to the need of an in-depth analysis of the regulations concerning application of security measures. This article constitutes a detailed comparison of the existing regulations with the new solutions, describes the totally different wording of Chapter X of the Penal Code, which allows for a much greater freedom and flexibility as regards using security measures, and notes an attempt of the legislator to systematise criminal law by introducing to the Penal Code the solutions that are regulated in specific acts, such as electronic tagging or handling dangerous persons.
