where these persons are accommodated. In this regard, the MNZ explained that brochures and posters concerning the rights of persons deprived of liberty were in these rooms at the time of the NPM visit, but members of the NPM conducting the visit did not notice them. Furthermore, recommendations that police officers insert accurate information about the presence of an expert worker of a social work centre when discussing unaccompanied minors of foreign nationality in the form „Implementation of tasks during detention/custody – official note“ were also not accepted. 2.4 VISITS TO POLICE STATIONS The systemic recommendations (15) dealt with various fields of the police officers’ work. Two systemic recommendations referred to the filling of vacant police officers’ or duty officers’ posts. The recommendation to examine the possibility of re-introducing permanent 24hour service at certain police stations was made particularly because police officers from these police stations (e.g. Gornja Radgona and Dravograd), which have suitable premises for detention of persons deprived of their liberty, must transport detained persons to police stations several tens of kilometres away. Such transportation is not always the most appropriate procedure; furthermore, the presence of police officers in the area of their respective police station diminishes when they carry out transportation of persons. Relating to the foregoing, the MNZ replied that the Police had been experiencing a significant lack of staff which it has been striving to reduce for some time, but this is an ongoing process of many years. Several other systemic recommendations referred to police procedures relating to foreigners and concerning the need for consistent recording of their treatment, e.g. in what way the foreigner was informed about their rights relating to the deprivation of liberty, and especially if they were informed about the possibility of filing an application for international protection/asylum. We assert that the documentation related to police procedures, especially involving persons who reported persecution due to any circumstance as the reason why they have left their country of origin, must be sufficiently precise in all cases so that it eliminates doubt about whether international protection has been adequately presented (for example, with brochures) and been explained to a person, and that it be determined whether or not that person has decided to exercise this right. Since it is difficult, given the mixed migrant flows, to clearly define in the course of the short police procedure the reason why a person has left their country of origin (which the documentation requires), what is also important is the ability of police officers to observe possible signs that the person needs international protection. We reminded the MNZ that, in our opinion, group interviews with foreigners do not enable the recognition of individuals who may need international protection or are victims of human trafficking, and do not enable the establishment of circumstances requiring the observance of the non-refoulement principle. We would like to note that the non-refoulement principle not only protects persons from being returned to their country of origin, but also from chain refoulement.
