A/HRC/4/47 page 10 the principle of sustainable development, given the link between development and the environment. 36. Another delegate underlined the importance of engaging civil society and ensuring the participation of the most marginalized in partnerships under review. Some delegates also underlined the importance of clarifying that the criteria equally applied to all parties to a partnership. 37. On the recommendations for a continued dialogue with the partnerships that were reviewed by the task force, and the addition of new partnerships, some delegates reiterated the fact that all the previous partnerships reviewed by the task force were related to Africa and requested that the review in the next phase of the task force activities be limited to the Cotonou partnership, without excluding the possibility of reviewing other partnerships at a later stage. 38. Several delegates and groups reiterated their position that the work of the task force contribute to an eventual elaboration of a convention on the right to development. However, other delegations and groups opposed any reference to starting work on drafting such a convention or an automatic link between the work of the task force and a convention. The Chairperson of the Working Group called upon the delegates to focus on common ground, such as the importance of the right to development and the primary objective of its implementation and realization. The Chairperson pointed out that the work of the task force was focused on precision of the content of the right to development, which would be a prerequisite for any move towards an international legal instrument on the right to development. 39. Concerning the recommendation that the task force undertake technical missions to continue the dialogue with the partnerships hitherto considered, as well as to continue the work on refining the criteria, Japan stated that it reserved its position on the possibility of undertaking such missions in the context of negotiations concerning a resolution on the right to development at the fourth session of the Human Rights Council. 40. Finally the proposal to add two days to the next meeting of the task force was supported by the Working Group, as well as the recommendation to request the Human Rights Council to renew the mandate of the Working Group and the task force for a period of two years. B. Consideration of the reports of the United Nations High Commissioner for Human Rights 41. The Working Group considered the reports of the United Nations High Commissioner for Human Rights on the right to development (E/CN.4/2006/26 and A/HRC/4/55), which were presented by the secretariat, and discussed the type of support that the Working Group and the task force would need from OHCHR for the work ahead. Both the Chairperson of the task force and the Chairperson of the Working Group expressed their deep appreciation for the high-quality level of substantive and material support and assistance provided by the Secretariat on this mandate and stated that the support of the Secretariat in continuing reviews of the previous partnerships, as well as in reviewing new partnerships, would be essential.
