A/HRC/9/9 page 18 General Assembly with the solemn proclamation of the International Year of the World’s Indigenous People in 1993,33 and subsequently, with the proclamation of the First Decade of the World’s Indigenous Peoples (1994-2004)34 and the Second Decade and plan of action.35 61. In view of this special role, the Declaration in article 41 explicitly calls upon the organs and specialized agencies of the United Nations system “to contribute to the full realization” of the Declaration, including, inter alia, through the mobilization of “financial cooperation and technical assistance”. Article 42 further underlines the role of United Nations bodies and specialized agencies, calling on them to “promote respect for and full applications of the provisions” of the Declaration and provide “follow-up” for its effective application. This is a joint task that pertains specially to United Nations human rights bodies and mechanisms, including but not limited to those with a particular mandate regarding the rights of indigenous peoples, as well as to the various United Nations programmes which in some way touch upon indigenous issues. Human rights bodies and mechanisms 62. As seen, United Nations human rights mechanisms and bodies have played a crucial role in promoting and protecting the rights of indigenous peoples, while contributing to the development of a common normative understanding concerning the minimum content of these rights. Currently the most authoritative expression of this common understanding, the Declaration on the Rights of Indigenous Peoples constitutes an important tool in the regular promotional and protective activities of these bodies within their respective mandates and normative frames of reference. 63. The recently inaugurated mechanism of the Universal Periodic Review (UPR) of the Human Rights Council is an important tool in promoting the rights affirmed in the Declaration. Given the complementary and interrelated character of international human rights law, as well as the existing and developing jurisprudence on various human rights treaties by international bodies and mechanisms, it is clear that the provisions of the Declaration should factor into the interpretation of States’ international human rights obligations and the evaluation of the positive developments and challenges faced when implementing them. It is foreseeable that, as the Declaration is gradually mainstreamed and operationalized in the practice of both States and human rights bodies and mechanisms, it will become entrenched in the UPR process, contributing to defining the human rights obligations of the States under review and guiding the recommendations of the Human Rights Council’s Working Group on the Universal Periodic Review with regard to indigenous peoples. 33 General Assembly resolution 45/164. 34 General Assembly resolution 48/163. 35 General Assembly resolution 59/174.
