A/HRC/12/28 page 8 25. With respect to the Intergovernmental Working Group on Public Health, Innovation and Intellectual Property, a delegation emphasized the importance of the Global Strategy and Plan of Action, urging the task force to synthesize into the criteria the affordability and access dimensions of health care and medicines, as well as flexibilities envisaged in the Trade-Related Aspects of Intellectual Property Rights Agreement. A civil society representative underlined the importance of the United Nations Declaration on the Rights of Indigenous Peoples for the realization of their right to development, including for the protection of indigenous knowledge. 26. In relation to the recommendation of the task force relating to a dialogue with MERCOSUR, the representative of Paraguay, speaking on behalf of MERCOSUR and associated States, informed the Working Group that the issue had been discussed at the last meeting of high officials responsible for human rights and ministries of foreign affairs, and a response to the invitation would be communicated to the task force as soon as an official position had been received from the capitals. 27. With reference to the issue of debt relief, some delegations proposed that the task force should interact with the independent expert on the effects of foreign debt and other related international financial obligations of States on the full enjoyment of all human rights, particularly economic, social and cultural rights, the independent expert on the question of human rights and extreme poverty and the Special Representative of the Secretary-General on human rights and transnational corporations and other business enterprises with a view to reviewing the impact of debt burdens and related issues on the right to development. 28. The Chairperson of the task force made a presentation on a informal chart he had prepared at the request of various delegations showing the linkages between each of the revised criteria, the relevant article of the Declaration, the previously endorsed criterion and the specific development partnerships which had been assessed from the perspective of the right to development and had contributed to the development or refinement of the criterion concerned. Also at the request of delegations, the Chairperson distributed informal lists of illustrative sub-criteria accompanying the revised criteria which had resulted from the work undertaken by a consultant to the task force, as well as from the expert meeting on methodological issues relating to the measurement of compliance with the right to development. It was noted that those lists were not considered by the task force as sufficiently developed to be shared with the Working Group but were distributed as a non-paper with the sole objective of providing some idea on the nature of the sub-criteria to be developed by the task force. Such lists were not discussed nor officially considered by delegations. 2. Right-to-development criteria 29. The Chairperson of the task force explained how the task force had approached the elaboration of criteria and operational sub-criteria or indicators for the implementation of the right to development. The methodology used in the formulation of criteria had evolved in light of the evaluation of partnerships the task force had examined. However, the primary sources of the interim draft list of criteria (as listed in annex IV to the task force report) were the Declaration on the Right to Development and the criteria as endorsed by the Working Group in 2006. The task force also considered as secondary sources the commissioned expert studies and recommendations of an expert meeting on methodological issues held in January 2009.
