INTRODUCTION The past year has become a true test for our country. The Revolution of Dignity, occupation of Crimea, the start of hostilities in Eastern Ukraine, and spread of terrorist threat across the country created new challenges for the national preventive mechanism that had to adapt quickly in rapidly changing environment. For instance, during the Revolution of Dignity, the NPM made it possible to obtain upto-date information about the fate of Maidan activists subjected to mass detentions by law enforcement officials. In close cooperation with the Department of Special Proceedings of the Secretariat of the Ukrainian Parliament Commissioner for Human Rights, representatives of the NPM Department were performing functions of urgent response regularly verifying information on human rights violations in different institution, responding to concrete complaints about torture and ill-treatment. The first chapter of the Report describes identified violations and acts of response of the Commissioner. An in-depth account is presented in the Special Report of the Commissioner for Human Rights titled “Violations of Human Rights in Ukraine during events of November 2013 – February 2014”. Importantly, materials of the Special Report were used in preparation of submission to the International Criminal Court in The Hague by nongovernmental organizations in cooperation with the Secretariat of the Commissioner. The aim of the submission was to call for consideration of initiating proceedings into crimes against humanity committed during the Revolution of Dignity. In fact, the Commissioner’s report was the first official document with a systemized account of all human rights violations that took place during the Revolution of Dignity. In addition, all materials of proceedings, including correspondence of the Commissioner for Human Rights with the Office of the Prosecutor General and the Ministry of Internal Affairs on the matter of investigation of human rights violations, were submitted to the International Advisory Panel (IAP) on Ukraine of the Council of Europe. The International Advisory Panel was constituted by the Secretary General of the Council of Europe to oversee the investigations into the violent incidents which took place in Ukraine during Maidan protests from 30 November 2013 to 21 February 2014. In his letter to the Commissioner for Human Rights, the IAP chairman and the former President of the European Court of Human Rights commended the expert level of materials collected in the framework of the Commissioner’s proceedings, as well as expressed gratitude for support to the investigation of violations during the Revolution of Dignity. 4
