The right to Social Security is one of the rights which appears in two important instruments of human rights—that is, the Universal Declaration of Human Rights and the Covenant on Economic, Social and Cultural Rights. The devotion of a separate article to right of Social Security in these two universal instruments indicates that this right is essential in the views the framers of the Declaration as well as international convention. Despite the emphasis put by the Declaration on international cooperation for implementing this right, unfortunately the appropriate action has not been taken yet in international scale. The low tendency to Social Security must be related to the economic problems surrounding this right. The low tendency to Social Security can also be seen in the regional instruments of human rights. These instruments have not mentioned the term “social security” independently; just there are general indications in some famous conventions of International Labor Origination (ILO). Of course in some special protocols prepared on specific issues by regional originations, Social Security has been discussed which is not convincing at all. If regional originations had been serious about implementation of Social Security as a human right, they should have referred to it in the original and mother text.
