The study focuses on several issues concerning the penalty of restriction of liberty. On the one hand, changes in the scope of the penalty may have a positive impact on the process of carrying it out, e.g. simplifying it, streamlining the work of individual bodies involved in the executive process, reducing the number of tasks or the burden of cases. On the other hand, individual changes may adversely aff ect the process of carrying out this penalty, complicating it, causing unnecessary burdening of executive bodies with
cases or tasks within the enforcement process. There is also a third possibility, namely — partly positive and partly negative impact of the changes.
