As explained in more detail in chapter II, the Committee may also take urgent action if it receives urgent requests that a disappeared person should be sought and found. It may conduct inquiry procedures into a State party if it receives reliable information about serious violations of the Convention and may bring these to the urgent attention of the General Assembly if they are widespread or systematic. Finally, article 27 foresees that the State parties will assess the functioning of the Committee and may decide to transfer its functions to another monitoring body. J.  Reading the treaties as a whole To understand a State’s obligations under these treaties fully, it is necessary to read all the human rights treaties to which a State has become a party together. Although separate and free-standing, the treaties also complement each other, with a number of principles binding them together. Each lays down, explicitly or implicitly, the basic principles of non-discrimination and equality, effective protection against violations, special protection for the particularly vulnerable, and an understanding of the human being as an active and informed participant in the public life of the State where he or she is located and in decisions affecting him or her, rather than a passive object of the authorities’ decisions. All the treaties based on these common principles are interdependent, interrelated and mutually reinforcing, so that no right can be fully enjoyed in isolation, but depends on the enjoyment of all the other rights. This interdependence is one reason why the human rights treaty bodies are crafting a more coordinated approach to their activities, in particular by encouraging State parties to see implementation of the provisions of all these treaties as a single objective. These treaties do not purport to be a definitive catalogue of a State’s human rights obligations. Many States, beyond their participation in the United Nations human rights treaty system, are also a party to regional human rights instruments, which may further expand the protection offered to persons within their jurisdiction. In addition, other treaties, including the Convention relating to the Status of Refugees and the conventions of the International Labour Organization (ILO), such as ILO Conventions No. 138 concerning Minimum Age for Admission to Employment and No. 182 concerning the Prohibition and Immediate Action for the Elimination of the Worst Forms of Child Labour, or ILO Convention No. 169 concerning Indigenous and Tribal Peoples in Independent Countries, are instruments with obvious and important human rights dimensions. All these international legal obligations should be considered together when evaluating a State’s responsibility to protect human rights. 18
