Specifically, the workshop discussed the various roles played by national human rights institutes in the protection and promotion of economic, social and cultural rights from a comparative perspective and the use of indicators as a means for monitoring economic, social and cultural rights, with a particular focus on the framework on human rights indicators developed by the Office. It also examined the specific international norms applicable to the right to health and to labour rights. 25. OHCHR has been active in advocacy for the legal protection of economic, social and cultural rights and the ratification of the Optional Protocol to the International Covenant through capacity-building, awareness-raising events and support to national organizations. Thus, in 2011, workshops were held, for instance, in Burkina Faso, Cape Verde and in Mali for a variety of participants, including judges, high-ranking Government officials, legislators, civil society organisations and lawyers. Cape Verde signed the Optional Protocol on 26 September 2011. 26. In July 2011, OHCHR organized several events in Costa Rica and Panama to promote the ratification of Optional Protocol and to raise awareness of the justiciability of economic, social and cultural rights. The activities included representations before the International Relations Committee of the National Assembly and the Ombudsman’s Office in Costa Rica to discuss the content of the Optional Protocol and the opportunity for ratification, and two events in Panama on the justiciability of economic, social and cultural rights and on the Optional Protocol with the Ministry of Foreign Affairs and the Ombudsman’s Office. 27.
