27 In order to concurrently satisfy both the requirement of confidentiality and transparency in work, the NPM Report made upon the visits to institutions, containing all the personal data on that have been redacted, are published after the competent authorities express their opinion about the recommendations presented in the reports. All reports and answers of the competent authorities are published on the web page of the Protector of Citizens and subpage of the NPM. The concept of the NPM Methodology is to dedicate special attention to the protection of persons deprived of their liberty, of detention centre employees and any other persons who have had contacts with NPM, that notified NPM about the treatment of persons deprived of their liberty or reported the cases of mistreatment. The NPM of Serbia is particularly focused on the prevention of retaliation in a way to protect all sources of information and/or details about individuals who provided these information. In case their identity is disclosed, as a prevention, NPM makes subsequent visits to these persons and oversees their situation, specifically, the way they are being treated by the staff in the detention centres. In addition, the responsible persons are being cautioned that any retaliation against the persons who cooperated with NPM would represent the worst form of abuse. The NPM Methodology envisages intensive activities aimed at fighting against impunity of torture, or any other form of mistreatment. Such activities, or any other behaviour representing torture are being signalled to all the competent authorities, with the expectation that in such cases, they will take any available measures and actions under their jurisdiction to investigate the accountability of their employees. The NPM of Serbia takes note of activities of competent authorities in order to fight the impunity of torture and establish both the individual and objective accountability. 4.2. Material resources and financial independence of the NPM In order for NPM to be able to successfully perform its tasks in line with its term of office set forth by the Law on Ratification of Optional Protocol, it is necessary to ensure the required material resources for its work and achieve its financial independence. The total amount of RSD 10,871,057.00 (around € 87,600.00) have been provided within the adopted budget of the Protector of Citizens, allocated for the provision of the NPM activities in 2016. In 2016, two offices in the office building of the Protector of Citizens were used by the NPM staff, including the van used for the transportation of the team members to the locations where they made visits. The NPM staff were able to use all the required office and other equipment and material (PCs, printers, laptops, photocopiers, humidity and distance meters etc.).
