ウィーン宣言及び行動計画
Economic, social and cultural right enshrined in international and regional human rights instruments are legally binding. Member states have a legal obligation to respect, protect and fulfil these rights. The exact nature of states' obligations in this respect has been established principally in relation to the International Covenant on Economic, Social and Cultural Rights (ICESCR), and further Optional Protocol to the International Covenant on Economic, Social and Cultural Rights has been established in accordance with Vienna Declaration and Programme of Action.
