A/HRC/23/32 A. Stakeholders 70. The Working Group calls upon all stakeholders: (a) To collect and exchange lessons learned from implementation efforts. Lessons learned from implementation efforts by States and business enterprises should be systematically shared with the Working Group. At the national, regional and sector levels, the exchange of these lessons learned should be facilitated, at both the policy and the working levels, between stakeholders. (b) To enhance guidance on effectiveness of remedy. Stakeholders are encouraged to collaborate in the efforts made by the Working Group to conduct further research and to establish more detailed guidance on effectiveness criteria for non-judicial remedy mechanisms. (c) To provide small- and medium-sized enterprises with guidance. States and business organizations should cooperate to raise awareness of the Guiding Principles among these enterprises, and to elaborate specific tools and guidance on implementation for them. (d) To address the situation of indigenous peoples. Stakeholders are encouraged to collaborate in the efforts of the Working Group to provide States and business enterprises with more detailed guidance on the implementation of the Guiding Principles in relation to indigenous peoples and potential or actual impact on their human rights relating to business activities, with due regard for the United Nations Declaration on the Rights of Indigenous Peoples. (e) To increase capacity to use the Guiding Principles. States, business enterprises, the United Nations system, regional organizations and other stakeholders are encouraged to collaborate to raise the awareness and capacity of all actors to use the Guiding Principles to improve the prevention of adverse impacts on human rights arising from business activities and to ensure accountability and remedy cases of impact when they occur. This should include special efforts to raise awareness and capacity to use the Guiding Principles by civil society organizations, human rights defenders and individuals or groups who are at a heightened risk of vulnerability to negative impact or marginalization. (f) To use the Principles for responsible contracts. States and business enterprises should raise the awareness and capacity of negotiators to use the principles for responsible contracts41 in State-investor negotiations. B. States 71. The Working Group calls upon all States, when implementing the Guiding Principles, to consider the following actions: (a) To designate responsibility for the implementation of the Guiding Principles and focal points in relevant ministries, and establish an interdepartmental group on the issue, or build on an existing mechanism for this purpose. States should avoid the compartmentalization of responsibilities on implementation of the Guiding Principles within single departments. The awareness and capacity of members of the group on the Guiding Principles should be built. The group should ensure collaboration with the national human rights institution. 41 20 A/HRC/17/31/Add.3.
