The duration of a specific visit depends on the size of the visited establishment and lasts 1 to 3 days. Every visit of the NMPT comprises the following stages: • conversation with the establishment’s managers, • inspection of all rooms used by persons deprived of their liberty, • individual and group conversations with detainees, • conversations with the personnel, • analysis of documents and video surveillance footage, • formulation of preliminary post-visit recommendations, • listening to the establishment managers’ opinions on the presented recommendations. If a person deprived of his/her liberty reports an unlawful event during the visit and expresses the desire to have it investigated, he/she has the opportunity to lodge an official complaint. The complaint is then forwarded to the competent team within the Office of the Commissioner for Human Rights. Yet, if the person does not consent to addressing the issue officially, the visiting team shall only use the information for the purposes of analyzing the operation of mechanisms intended to protect persons deprived of their liberty against degrading, inhuman treatment or punishment as well as against torture and for the purpose of presenting relevant recommendations. Pursuant to Article 21 (1) OPCAT No person (e.g. inmate, establishment’s employee, family member, another individual) or organization that provided the NMPT with information shall be subject to any sanctions or harm for that reason, regardless of whether the information in question was true or false. When the visit is completed, a report is drawn up which describes all the findings and conclusions, as well as recommendations for the body managing the visited establishment and for its supervisory authorities. If the establishment’s management does not agree with the recommendations, the NMPT representatives request the supervisory bodies to issue their opinion and position on the matter. Such a dialogue is conducted to indicate the merits of the NMPT’s recommendations whose implementation may strengthen the protection of the rights of persons deprived of their liberty at the visited place. During the visits, NMPT employees use the following measuring and recording devices: CEM DT-8820 multimeters, Makita LD060P laser rangefinders and digital cameras.
