South-East Europe NPM Network The NPM has participated in the activities of the South-East Europe NPM Network (hereinafter the “SEE Network”), whose members can more efficiently perform the task of preventing ill-treatment in cooperation with each other, as an observer since 2014 and as a full member since April 21, 2016. The participants of the conference entitled “Prevention of suicides and overdoses in detention centres and status of NPM staff in the member states” organised by the South-East Europe NPM Network in Podgorica, Montenegro between 28 and 30, May, 2018 presented how, in the member state that they represent, the admission of the detainees to prisons and police detention facilities, as well as the prevention of self-harming behaviour and suicide attempts take place. The regional round-table discussion entitled “Immigration Detention and Effective Alternatives” organised by the South-East Europe NPM Network in Podgorica, Montenegro between December 12 and 14, 2018, which was supported by the Council of Europe, was about the alternatives of the detention of immigrants. It became clear from the comments made by the participants that the countries of the region that typically fulfil the role of transit states in international migration find it hard to tolerate mass migration and to take care of those foreign nationals who have no personal identification documents. The places of detention are overcrowded, the migrants shortly leave the designated areas serving as alternatives to places of detention for unknown destinations, without notice. 12.2.2. Conferences The participants of the conference entitled “NPM Impact Assessment” organised by the ten-year-old Slovenian National Preventive Mechanism in Ljubljana, Slovenia on April 17-18, 2018 discussed the following topics in four workshops: • Why does the impact of the NPM need to be analysed, who has to do this and when? • What are the criteria of the impact assessment of the NPM? • How can the impact of the NPM be assessed? • How should the causal relation between the detected changes and the NPM’s activity be established?
