8. Recommendations of the National Preventive Mechanism.   As a result of the activities carried out during 80 preventive visits in 2010, the National Preventive Mechanism has issued recommendations aimed at the proper implementation of the standards contained in the acts of international and internal law.

Furthermore, in the rooms intended for inmates posing a serious social threat or a serious threat to the safety of the establishment also those prisoners who have not been included in that group and due to the special rigour and securities in such sections should not be housed here, were placed.
