Firstly, an attempt was made to determine to what extent it is consistent with the entire system of execution of penalties and penal measures, especially against the background of recent changes in the area of deviations from the principle of continuity of punishment. Secondly, a detailed analysis of the correctness of the regulation of this provision was conducted in terms of its eff ective and ratio legis application to addicted prisoners.
