PP N PM ANNUAL REPORT ON THE PERFORMANCE OF ACTIVITIES OF THE NPM Taking into account that OPCAT, on the basis of which National Preventive Mechanisms are established, was adopted only in 2005, and that these are mechanisms which in many Member States are only in the process of establishment, cooperation has started with the Protector of Human Rights and Freedoms of Montenegro and with the institution of Ombudsperson of Slovenia (within which the National Preventive Mechanisms of these countries operate). Within this cooperation, study visits took place (a visit of the NPM of Montenegro to the NPM of Croatia in September 2012 and a visit of the NPM of Croatia to the NPM of Montenegro in October 2012; a visit to the NPM of Slovenia in November 2012). The goal of the study visits was to exchange present experiences and to become familiar with the method of work of the institutions which operate under the authority of the NPM. 28
