97 10. Dialogue on the measures taken by the NPM Pursuant to Article 22 of OPCAT, “the competent authorities of the State Party concerned shall examine the recommendations of the national preventive mechanism and enter into a dialogue with it on possible implementation measures”. In lack of OPCAT requirements regarding the dialogue between the NPM and the competent authorities, it is the fundamental principles defined by the Subcommittee on Prevention that have governing effect in the question mentioned above.183 The NPM • should maintain a dialogue with “both governmental authorities and institution directors/managers regarding the implementation of recommendations”,184 • “should establish sustainable lines of communication” and “a mechanism for communicating and cooperating with relevant national authorities on the implementation of recommendations”;185 • should maintain a dialogue that involves “both written and oral exchanges”.186 Although the implementation of the measures recommended by the NPM is not mandatory, the Ombudsman Act compels the measures’ addressees to respond on the substance of the recommendations aimed at eliminating the improprieties, or the threat thereof, uncovered during the inspection. Maintaining continuing and constructive dialogue serving the monitoring of the implementation of these measures is a statutory obligation of not only the NPM but also the management of the places of detention, authorities, and other organs concerned. The dialogue between the NPM and the addressees of the recommendations is conducted on the basis of the report used as a platform. The Ombudsman Act regulates in detail the method of monitoring, including the deadlines for responding.187 183 184 185 186 187 Point 1, Section (iii) of Article 11 of OPCAT.
