As of 2008 the Ombudsman is the only national human rights institution (NHRI) in the Republic of Croatia with the “A” status according to the Paris Principles. It is the highest status conferred by the UN on national human rights institutions. In order to be eligible for such a status an institution needs to be completely independent in the performance of its work and have a broad mandate in both the protection and promotion of human rights as well as reliable and sustainable institutional capacities in order to be able to perform such a prominent role adequately.
As of 2009, the Ombudsman is the central equality body according to the Anti-discrimination Act. According to the Act on National Preventive Mechanism against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (ANPM) brought in 2011, the Ombudsman is also the National Preventive Mechanism Against Torture and Other Cruel, Inhuman and Degrading Treatment or Punishment.
It was the obligation of the Republic of Croatia to introduce the requirements connected to status “A” into its legal system. Therefore, following the Constitutional changes in 2010, a new Ombudsman Act was passed in July 2012. With this Act, the institution's mandate was defined and extended in the field of promotion of human rights, outreach, research, institutional cooperation with the specialized ombudspersons as well as in the field of cooperation with civil society organizations. The Act also stipulated the institutional merger of the Human Rights Center with the Office of the Ombudsman in order to enhance the Ombudsman's capacity for human rights promotion.
