Since International bill of rights divided into two covenants: International covenants on civil and political rights (ICCPR) and International Covenant on Economic, Social and Cultural Rights (ICESCR), human rights are also seemed divided into two categories and two different types of legal natures. While civil and political rights have attracted much attention in the international society, economic, social and cultural rights have very often considered as not legal rights and been ignored under the human rights law system. In 1993, Vienna Declaration and Programme of Action, adopted in the World Conference on Human Rights, reaffirmed the indivisibility and interdependence of all human rights. However, the controversies are still going on. This paper mainly will focus on history and legal nature of ICESCR article 2 under relation with indivisibility of human rights. Also would like to focus on the work of new Committee on Economic, Social and Cultural Rights, especially General comments. Hope this process will be help to understand ICESCR also create legal rights and States parties have legal obligations under the covenants.
